Ohio Tax Preparer Requirements 2025-2026

Ohio is one of the most accessible states in the country for independent tax preparers: no state license, no exam, no state-mandated continuing education, and no bond requirement. Any individual with a federal PTIN ($18.75 per year) may legally prepare Ohio income tax returns for compensation. What Ohio does require is a working command of three things that most competing guides barely cover: the Business Income Deduction (Ohio's most powerful tax provision for self-employed clients, with the first $250,000 of qualifying business income effectively exempt from Ohio income tax), the Ohio individual income tax rate structure transitioning toward a flat tax, and the state's fragmented municipal income tax system spanning more than 600 local jurisdictions administered through RITA, CCA, and dozens of independent city departments. The preparer who understands Ohio's municipal mechanics well is far more valuable to Ohio clients than one who only knows the state return. This guide covers every requirement a non-credentialed Ohio paid preparer needs for TY2025 returns filed in 2026.

Does Ohio Require a State Tax Preparer License?

Ohio does NOT require non-credentialed paid tax preparers to obtain a state license, pass an exam, register with any state agency, or complete state-mandated continuing education. The Ohio State Board of Accountancy has no authority over non-credentialed tax preparers. Ohio imposes no surety bond requirement and no state registration fee. An individual may begin preparing Ohio or federal returns for compensation the moment they hold a valid federal PTIN.

Compare this to regulated states: California requires CTEC registration with 20 hours of annual CE, Oregon requires a Licensed Tax Consultant or Tax Preparer credential, and Maryland and New York impose their own state-level requirements. Ohio imposes none of these. It is a fully open market.

What Non-Credentialed Preparers Cannot Do

Non-credentialed preparers may NOT use the title "CPA" or hold themselves out as licensed public accountants. They may not perform audits, reviews, or compilations, and they may not represent clients before the IRS unless they hold an active AFSP Record of Completion (limited representation rights for returns personally prepared) or a credential such as an Enrolled Agent designation. Without AFSP, a non-credentialed preparer's authority ends once the return is filed.

PTIN: The One Mandatory Federal Requirement

Every paid preparer of federal tax returns must hold a Preparer Tax Identification Number (PTIN). The 2026 fee is $18.75 per year, paid at irs.gov/ptin. Renewal opens each October 16 for the following calendar year and takes approximately 15 minutes online. The PTIN must appear on every federal return you sign. Ohio does not require a separate state preparer identification number; the federal PTIN covers Ohio returns.

EFIN: Required at 11 or More Returns Per Year

An Electronic Filing Identification Number (EFIN) is required for any preparer who e-files 11 or more federal returns in a calendar year. EFIN applications are submitted through IRS e-Services; the approval process typically takes four to six weeks and includes a suitability check. Ohio participates in the IRS Fed/State e-file program, so a single EFIN covers Ohio state returns. There is no Ohio-specific e-file mandate threshold; the federal 11-return rule applies.

AFSP: The Voluntary Credential That Matters in Ohio

Because Ohio has no state credential for non-credentialed preparers, the IRS Annual Filing Season Program (AFSP) Record of Completion is the most meaningful differentiation available. AFSP requires 18 hours of continuing education each year (including a 6-hour federal tax law refresher with a proctored test), earns you a listing in the IRS public directory, and grants limited representation rights before the IRS on returns you personally prepared. In a state where most competitors hold nothing, an AFSP Record of Completion is a concrete credential you can show clients and display on your website. America's Tax Professionals (ATP) is an IRS-authorized CE provider (provider number P619F) that offers AFSP-qualifying courses.

FTC Safeguards Rule (WISP): Required for Every Preparer

Every paid tax preparer, including solo practitioners in Ohio, must maintain a Written Information Security Plan (WISP) under the Gramm-Leach-Bliley Act. Required elements include a designated responsible individual, multi-factor authentication on all systems containing client data, a documented risk assessment, and a written incident response plan. FTC civil penalties reach up to $46,517 per violation per day. A free WISP template is available in IRS Publication 5708.

Ohio also requires notification to affected individuals and the Ohio Attorney General within a reasonable time after discovering a security breach involving personal information under Ohio Revised Code 1349.19.

Ohio Individual Income Tax for TY2025

Income Tax Rate Structure

Ohio has been on a multi-year path of rate reduction. For Tax Year 2025 (returns filed by April 15, 2026), Ohio uses a three-tier structure on nonbusiness income:

The $26,050 zero-rate threshold functions as Ohio's low-income relief mechanism. Taxpayers at or below this threshold owe no Ohio income tax. Ohio has NO standard deduction; it uses personal exemptions instead (see below).

TY2026: Ohio Moves to a True Flat Tax

Starting Tax Year 2026, Ohio eliminates the 3.125% bracket and moves to a single flat rate of 2.75% on all income above the $26,050 zero-rate threshold. Brief clients now on this change: higher-income W-2 earners will see a modest rate reduction in 2026, while the $26,050 floor remains in place. Ohio cut its top rate from 4.997% in 2021 to 3.125% in 2025 to a flat 2.75% in 2026, representing a substantial multi-year reform.

Personal Exemptions (TY2025)

Ohio provides personal exemptions (one per filer, one per dependent) that phase down based on Modified Adjusted Gross Income (MAGI):

Ohio MAGI is calculated as Ohio AGI (IT 1040, line 3) plus the Business Income Deduction claimed. This prevents the BID from artificially lowering MAGI for exemption-tier purposes. The $750,000 MAGI cap tightens to $500,000 in TY2026. A married couple with three dependents at the $40,000-or-less tier can claim five exemptions at $2,400 each ($12,000 in total reductions) before the 0% bracket itself.

Social Security and Retirement Income

Ohio does not tax Social Security benefits or Railroad Retirement benefits. Both are fully subtracted when computing Ohio AGI. Military retirement pay is also fully exempt starting TY2024 (see the military section below). Ohio Public Employees Retirement System (OPERS) distributions and private pension income, however, are subject to Ohio income tax, though they are not subject to Ohio municipal income tax or school district income tax.

Joint Filing Credit

Married couples filing jointly in Ohio where both spouses have qualifying income may claim the Joint Filing Credit, a nonrefundable credit that rewards two-income households. The credit rate scales based on the ratio of the lesser-earning spouse's income to combined Ohio income. The Joint Filing Credit is not available to taxpayers with MAGI above $750,000 (tightening to $500,000 in TY2026). Always calculate this credit on joint returns; it can meaningfully reduce liability for two-income Ohio households.

The Ohio Business Income Deduction: Ohio's Biggest Preparer Differentiator

No other provision in Ohio tax law creates more immediate, measurable client value than the Business Income Deduction. Preparers who understand and correctly apply it deliver results that self-filing clients consistently miss. The mechanics are specific enough that even clients who use a major national chain often leave this deduction on the table.

What Income Qualifies for the BID

Ohio business income is income from a sole proprietorship or pass-through entity. The qualifying sources are:

• Schedule C: Net profit from self-employment
• Schedule E (partnerships and S-corps): Net income from K-1s where the entity operates a business
• Schedule F: Net profit from farming operations
• Rental income that rises to the level of a trade or business (material participation; document carefully)

W-2 wages, interest, dividends, and capital gains from investment portfolios do NOT qualify. The distinction between business income and investment income is a core preparedness question for every self-employed client.

How the BID Works: Schedule IT-BUS

The deduction operates in two tiers, calculated on Schedule IT-BUS:

• First $250,000 of qualifying business income (single filers; $125,000 for married filing separately): 100% deducted from Ohio AGI. This income is exempt from Ohio individual income tax.
• Business income above $250,000: taxed at a flat 3% on Schedule IT-BUS, separate from and instead of the regular 2.75%/3.125% brackets.

Worked example 1 (solo preparer with $180,000 net profit): A self-employed tax preparer earns $180,000 net from their Schedule C practice. The full $180,000 is deducted via BID. Ohio income tax on that business income: $0. The preparer's remaining W-2 income (if any) is taxed at the regular bracket rates. Result: a solo practitioner at typical Ohio prep-firm revenue pays effectively zero Ohio income tax on practice earnings.

Worked example 2 (small S-corp owner with $350,000 pass-through): A business owner receives $350,000 in Schedule E pass-through income from an S-corp. The first $250,000 is deducted via BID (Ohio tax: $0). The remaining $100,000 is taxed at the flat 3% rate on IT-BUS ($3,000 Ohio tax). Without BID, the full $350,000 would have been taxed at up to 3.125%, producing roughly $10,000 or more in Ohio tax. The BID saves this client approximately $7,000.

Worked example 3 (northwest Ohio farmer with $200,000 Schedule F): A corn and soybean farmer nets $200,000 from Schedule F. The full $200,000 is deducted via BID. Ohio income tax on farm income: $0. Combined with 100% bonus depreciation on equipment purchases (available through Ohio's SB 9 conformity to OBBBA, described below), a capital-intensive farm year can produce zero Ohio income tax on substantial gross income.

Pass-Through Entity Tax (PTET) Election and BID Interplay

For TY2025, Ohio pass-through entities may elect to pay Ohio income tax at the entity level (Form IT 4738), a SALT workaround allowing the entity-level tax to be fully deductible for federal purposes. Starting TY2025, upper-tier PTEs can directly claim credits for PTET paid by lower-tier entities, solving a prior multi-level stacking problem. Important: the Business Income Deduction is only claimable at the individual IT 1040 level, not on the PTE return. Preparers with PTE-electing clients should analyze whether the combined federal deduction benefit of PTET outweighs the lost BID before recommending the election.

Ohio Municipal Income Tax: The Most Complex Element in Ohio Returns

Ohio's local income tax system is one of the most fragmented in the United States. More than 600 municipalities levy their own income tax, with rates, filing deadlines, forms, and collection agencies that vary by city. No other aspect of Ohio tax practice differentiates a knowledgeable preparer from a careless one more than this section. The preparer who can navigate RITA, CCA, independent city filings, the 20-day rule, the dual-obligation framework, and the post-COVID remote work rules is providing a service that most consumer tax software cannot fully replicate.

The Three Administrative Channels

Ohio municipal tax is collected through three separate systems. Determining which channel governs each city in a client's return is the first step in every Ohio municipal analysis.

Channel 1: RITA (Regional Income Tax Agency)

RITA administers income tax for more than 390 Ohio municipalities, covering more than 450 taxing jurisdictions as of 2025. It is the largest single administrator. Notable RITA members include Akron (2.5%), Youngstown (2.75%), Parma, and hundreds of suburban communities across northeast and central Ohio. RITA does NOT administer tax for Cleveland, Columbus, or Cincinnati.

Key RITA facts for preparers: Individual returns use Form 37 (one form covers all RITA member cities). The filing deadline is April 15. Online filing is through RITA's MyAccount portal at ritaohio.com. RITA publishes a public Tax Rates Table showing the tax rate and the credit rate for each member city. Always check this table to confirm credit rates before calculating net municipal liability.

Channel 2: CCA (Central Collection Agency)

CCA administers tax for approximately 40 municipalities. Its most important member is Cleveland (2.5%). CCA is located at 205 W. Saint Clair Ave., Cleveland, OH 44113. Individual filers use the CCA eFile system or paper forms. One critical operational difference: refund claims for CCA member cities require paper filing at the CCA Main Office. The online eFile system does not process refunds as of 2025. Preparers with Cleveland-area clients who are due refunds (particularly remote workers over-withheld for Cleveland) must mail the paper return to the CCA address. Employer withholding is due monthly if more than $200 per month is withheld, or quarterly for smaller amounts.

Channel 3: Independent City Departments

About 50 Ohio cities collect their own municipal income tax entirely independently of RITA or CCA. Key examples:

• Columbus (2.5%): Columbus City Auditor, Income Tax Division; online filing portal at columbus.gov
• Cincinnati (1.8%): City of Cincinnati Finance Department (rate effective October 2, 2020; the lowest rate among Ohio's major cities)
• Toledo: City of Toledo Taxation and Treasury Division; verify the current 2025 rate at toledo.oh.gov before completing any Toledo return
• Canton (2.5%): Stark County area; verify the administering agency at the city's official site before filing

The Dual-Obligation Rule: Work City and Home City

Every Ohio resident with earned income potentially owes municipal income tax to TWO jurisdictions simultaneously: (1) the city where they work, withheld by the employer; and (2) the city where they live, paid directly or as a balance due. This dual-obligation framework is the foundation of every Ohio municipal return.

How the credit prevents double taxation: Most Ohio municipalities allow a resident credit against their home-city tax for municipal tax paid to the work city, capped at the home-city rate. The practical result: a worker generally pays whichever rate is higher (work city or home city), not both combined.

Critical verification rule: always confirm the specific credit rate for each home city before calculating. RITA publishes its Tax Rates Table at ritaohio.com. Some municipalities cap the credit below their full tax rate, meaning a worker could owe partial tax to both cities.

Principal Place of Work (PPOW): The Core Withholding Concept

Ohio employer withholding is based on the employee's Principal Place of Work (PPOW), ordinarily the employer's physical office address. The employer withholds to that municipality. This matters enormously for hybrid and multi-location workers: if a client's employer address is in Columbus but the client works two days per week from home in a Dublin suburb, there are potentially two different municipal tax obligations depending on day counts and the remote work rules.

The 20-Day Rule: Critical for Multi-Location Workers

If an employee works in a municipality other than their PPOW for 20 or fewer days in a calendar year, the employer does NOT need to withhold for that other municipality. All withholding continues to the PPOW city. Once the employee works 21 or more days in the non-PPOW city during the year, the employer must begin withholding for that city starting with day 21.

The count is per-municipality per-calendar-year. A day counts as being in only one municipality even if the worker travels between cities during the day (the dominant location applies). Self-employed individuals: the 20-day rule is an employer withholding rule. Self-employed workers who perform services in multiple cities must allocate and file directly with each city regardless of day count.

Post-COVID Remote Work and Municipal Tax: The High-Stakes Compliance Trap

This is the most consequential unresolved compliance issue in Ohio municipal tax, and it affects a substantial portion of W-2 employees in any hybrid arrangement.

Pandemic rules (March 9, 2020 through December 31, 2021): Ohio enacted a temporary convenience-of-employer rule allowing employers to continue treating remote workers as if present at the PPOW. Work-city withholding continued even for employees working entirely from home. The Ohio Supreme Court ruled in 2024 that municipalities were constitutionally permitted to collect this tax during 2020 and 2021 even if the employee never physically worked in that city. Retroactive refund claims for those two years are effectively foreclosed for most workers.

Starting January 1, 2022: traditional rules restored. Remote workers now owe municipal tax to their HOME city for every day worked from home, not to the employer's city. If a worker's employer is in Columbus (2.5%) but the worker works from home in a Westerville suburb (RITA, 2.0%) three days per week, the worker owes Westerville tax on three-fifths of their wages and Columbus tax on two-fifths. If the employer continued withholding 100% to Columbus, the worker may be entitled to a partial Columbus refund for 2022 and forward, with a corresponding Westerville obligation.

Refund documentation requirement: To claim a refund for work-city over-withholding, the worker needs a signed letter from the employer on company letterhead from a direct supervisor confirming the number of days worked outside the PPOW during the calendar year. The refund is not self-evident from the W-2; preparers must ask the right questions and collect this documentation before filing.

Questions to ask every W-2 client in a hybrid or remote arrangement:

1. What city is your employer's office located in (your PPOW)?
2. How many days did you work from home versus the office this calendar year?
3. What city do you live in? Is it the same as your employer's city?
4. What do Box 18, 19, and 20 on your W-2 show (local wages, local tax withheld, locality name)?
5. Does your employer also withhold for your home city (courtesy withholding)?

School District Income Tax (SDIT): The Fourth Tax Layer

Separate from state income tax and municipal income tax, many Ohio school districts levy a School District Income Tax (SDIT), approved by local voter referendum. SDIT applies only to residents of the school district, not to workers who commute there. It is filed on Form SD 100 with the Ohio Department of Taxation. Rates range from 0.25% to 2.00% depending on the district.

Two SDIT types exist: traditional districts (tax based on Ohio taxable income) and earned-income-only districts (tax only earned income and self-employment income, not retirement income or investment income). Employers must withhold SDIT based on each employee's resident school district.

Many Ohio residents do not know they owe SDIT. The Ohio Department of Taxation's "The Finder" tool at tax.ohio.gov identifies the school district for any Ohio address. Run every client's home address through The Finder to confirm whether they owe SDIT before finalizing their return. Franklin County (Columbus area) and Cuyahoga County (Cleveland area) each contain dozens of school districts; many clients in these areas owe SDIT.

Self-Employed Clients and Municipal Tax

Self-employed individuals (Schedule C, Schedule F, freelancers) have no employer to handle withholding. They must file directly with each municipality where they perform work AND with their resident municipality. Quarterly estimated payments are generally required if annual municipal tax liability will exceed $200 (the threshold varies by city; verify locally).

A home-based preparer owes municipal net profit tax to their HOME city on their Schedule C net profit, not to the cities where their clients are located. This is an important distinction many solo preparers miss about their own business returns.

Ohio Business Gateway (OBG) centralized filing: Businesses and sole proprietors can elect to file all Ohio municipal net profit tax through a single return at gateway.ohio.gov, administered by the Ohio Department of Taxation. This replaces filing individually with each city and is a major simplification for preparers or clients who work across multiple Ohio municipalities. Registration for centralized filing is due by April 15 of the applicable tax year.

Major Ohio City Municipal Tax Rates (2025)

Note: Always verify rates and administrators at each city's official site or the RITA Tax Rates Table before completing any municipal return. Rates and administrators can change by city ordinance.

Ohio's Conformity to OBBBA: Senate Bill 9 (Signed March 2026)

Ohio is a static-conformity state, meaning it does not automatically adopt federal tax law changes. Ohio's prior conformity date was March 7, 2025. Governor DeWine signed Senate Bill 9 with an emergency clause in early March 2026, immediately updating Ohio's conformity to include the federal OBBBA (One Big Beautiful Bill Act) provisions enacted in 2025.

What Ohio Conformed to via SB 9

• Section 174 R&D expensing: Immediate deduction of research and experimental costs restored for Ohio returns (previously required 5-year amortization)
• 100% bonus depreciation: Full first-year expensing of qualifying property restored for Ohio purposes
• Qualified production property (IRC 168(n)): 100% depreciation for new domestic manufacturing facility components
• Section 163(j) business interest limitation: EBITDA-based calculation restored (more favorable than prior EBIT-based limit)
• Opportunity Zones: Capital gains deferral and exclusion provisions conformed
• Qualified Small Business Stock (QSBS): Expanded eligibility conformed
• Child and Dependent Care Credit: Ohio credit, calculated as a percentage of the federal credit, benefits from the enhanced federal base
• Dependent Care FSA exclusion: Increased from $5,000 to $7,500 conformed to Ohio
• 529 plan expanded withdrawals: Broader qualifying expenses conformed

OBBBA Tips and Overtime at the Ohio Level

Ohio's SB 9 updated conformity to OBBBA generally. For the specific treatment of the OBBBA tips deduction and overtime deduction on Ohio returns, consult the Ohio Department of Taxation's official guidance and the TY2025 IT 1040 instructions directly, as line-specific instructions for Ohio may differ from the federal treatment. Do not assume federal treatment applies at the state level without confirming from the Ohio Department of Taxation.

Practical Impact: Equipment-Heavy Clients

Manufacturing clients, farmers, and construction businesses with significant equipment purchases in 2025 can now immediately deduct those costs on Ohio returns under 100% bonus depreciation. Combined with the Business Income Deduction, a capital-intensive year for a sole proprietor or S-corp owner can produce very low or zero Ohio income tax. Proactively discuss TY2025 equipment purchases with any business client before the return is filed. Note: verify the specific Ohio treatment for bonus depreciation against Ohio Department of Taxation guidance for TY2025, as some Ohio conformity language has created uncertainty in past years about whether an Ohio add-back is required for a portion of bonus depreciation.

Ohio Commercial Activity Tax (CAT): What Preparers Need to Know

Ohio replaced its corporate income tax with the Commercial Activity Tax (CAT), a gross receipts tax assessed on the privilege of doing business in Ohio. Ohio has no traditional corporate income tax; the CAT is the primary business activity tax for most Ohio entities (sole proprietorships, LLCs, partnerships, S-corps, and C-corps).

2025 Exemption Threshold and Rate

For 2025 and beyond, the CAT exemption threshold is $6,000,000 in Ohio taxable gross receipts (raised from $3,000,000 in 2024). The rate above the threshold is 0.26%. The prior annual minimum tax structure ($150 to $2,600 based on receipt tiers) was completely eliminated starting in 2024. An entity with Ohio gross receipts under $6,000,000 owes no CAT, has no CAT filing obligation, and does not need to register for CAT.

For independent non-credentialed tax preparers: a solo practice generating $75,000 to $300,000 in annual gross revenue has zero CAT obligation. The $6,000,000 threshold makes CAT irrelevant for virtually every independent preparer's own business.

Preparers must still understand the CAT for business clients. Manufacturing firms, healthcare organizations, retailers, trucking companies, and large agricultural operations may exceed the $6,000,000 threshold and owe CAT at 0.26%.

Ohio Sales Tax and Tax Preparation Services

Tax preparation services are NOT subject to Ohio sales tax. Ohio sales tax applies to tangible personal property and certain specifically enumerated services; professional services including legal, medical, accounting, and tax preparation are generally exempt. Preparers do not need to collect or remit Ohio sales tax on service fees charged to clients.

Ohio's state sales tax base rate is 5.75%. Combined county rates (state plus county) range from approximately 6.75% (Summit County / Akron) to 8.0% (Cuyahoga County / Cleveland). This is relevant to preparer business operations (supplies, equipment, office space) but does not affect the billing of preparation services to clients.

Preparers who sell tangible items (printed publications, software on physical media) should verify Ohio sales tax treatment for those specific products. Digital and SaaS products have complex and evolving treatment; consult the Ohio Department of Taxation or a licensed Ohio CPA for definitive guidance before collecting or not collecting tax on digital products.

Starting a Tax Preparation Business in Ohio

Ohio LLC Formation

An Ohio LLC is formed through the Ohio Secretary of State.

• Articles of Organization filing fee: $99 (one-time)
• Annual report fee: None. Ohio does not require LLCs to file annual reports or pay renewal fees.
• Name reservation (optional): $39 for a 180-day hold
• Registered agent: Required; self-service is permitted; professional agent services range from $50 to $200 per year
• Processing time: 3 to 7 business days standard; expedited available for an additional $100 to $300

No annual LLC renewal fee is a meaningful advantage for Ohio-based practices. Formation at $99 and no recurring state entity fee makes Ohio an operationally low-cost state for independent preparer businesses.

City Business Registration

Ohio cities may require local business registration separate from the state LLC filing. Columbus requires a business registration for entities operating in the city. CCA member cities (including Cleveland) require registration through CCA if a business has taxable activity in those cities. Other cities vary; typical local registration costs range from $25 to $350. Check your specific home city's requirements before opening for business.

Recommended Formation Checklist for Ohio Independent Preparers

1. File Ohio Articles of Organization: $99 at ohiosos.gov
2. Obtain federal EIN at IRS.gov (free)
3. Obtain federal PTIN: $18.75 at irs.gov/ptin
4. Apply for EFIN through IRS e-Services if you plan to e-file 11 or more returns
5. Check your home city's business registration requirements
6. CAT registration: not required if gross receipts will remain under $6,000,000
7. Consider Ohio Business Gateway registration for centralized municipal net profit tax filing
8. Open a separate business bank account
9. Draft and implement your WISP (data security plan)
10. Enroll in AFSP if you want to differentiate with an IRS credential and representation rights

High-Value Ohio Client Niches

Manufacturing Workers: Toledo, Akron, Youngstown, Canton

Ohio is among the top U.S. states for manufacturing employment. Workers in Toledo (auto-adjacent, glass, logistics), Akron (Goodyear, polymer industry), Youngstown (steel legacy), and Canton (Timken, distribution) often live in suburbs administered by different agencies than their work city. Akron-area workers commonly file both an Akron RITA return and a suburb RITA return via consolidated Form 37. Youngstown's 2.75% rate (the highest among Ohio major cities) means the suburb credit analysis is especially important for workers living outside Youngstown proper. Toledo workers and their employer city rate should always be confirmed at toledo.oh.gov. Ohio-Indiana and Ohio-Pennsylvania reciprocity also applies: an Ohio resident working in Indiana or Pennsylvania owes only Ohio tax on those wages (and vice versa), eliminating dual filing in most reciprocity situations.

Cleveland Healthcare: Cleveland Clinic, University Hospitals

Cleveland hosts one of the highest concentrations of healthcare workers in the country. Cleveland Clinic employs more than 80,000 people system-wide; University Hospitals is a second major employer. Most clinical staff work in Cleveland (2.5%, CCA) while living in Cuyahoga County suburbs with rates typically between 2.0% and 2.5%. Every Cleveland healthcare worker return involves CCA filing, the suburb-credit analysis, and potentially SDIT. Hybrid administrative staff who shifted to home-office arrangements after COVID need a full PPOW analysis.

Medical residents and fellows are a specific underserved niche. First-year residents at Cleveland Clinic or University Hospitals typically earn $60,000 to $80,000 with training at multiple hospital locations, potential stipend income, and four separate returns: federal, Ohio state, Cleveland (CCA), and school district (SDIT). This is complex enough that most self-file incorrectly.

Columbus State Government Workers and OPERS

Ohio employs approximately 50,000 workers in Franklin County. State employees typically participate in OPERS (Ohio Public Employees Retirement System). OPERS employee contributions are deferred for federal income tax but ARE subject to Ohio municipal income tax. Box 20 on the W-2 for a state worker should show local taxable wages inclusive of OPERS deferrals; verify this before completing the Columbus city return.

Many state workers live in Franklin County suburbs (Dublin, Westerville, Hilliard, Grove City) administered by RITA at rates typically between 1.5% and 2.5%. A full-time in-office worker's Columbus 2.5% credit generally offsets the suburb obligation entirely. Remote and hybrid workers owe a prorated suburb obligation for home-office days. OPERS retirees: distributions are subject to Ohio income tax but NOT subject to municipal income tax or SDIT (retirement income, not earned income). This is a frequent confusion point.

Northwest Ohio Agriculture: Corn, Soybeans, and the BID

Ohio is a top-five U.S. producer of corn and soybeans. The primary agricultural counties (Putnam, Defiance, Henry, Paulding, Wood, Hancock, Allen, and others in northwest and western Ohio) contain thousands of family farm operations. Schedule F net profit qualifies for the Ohio Business Income Deduction in full up to $250,000. A farmer netting $200,000 from corn and soybeans owes zero Ohio income tax on that income. With SB 9 bonus depreciation conformity, a capital equipment purchase year compounds the advantage further.

CAUV (Current Agricultural Use Value) is Ohio's property tax relief program for farmland: land devoted exclusively to commercial agricultural use is assessed at CAUV rather than market value, producing substantially lower property tax bills. Qualification requires 10 or more acres of commercial ag use, or under 10 acres with average gross income of at least $2,500 per year. Farmers routinely ask preparers about CAUV; knowing its eligibility criteria is expected.

Military: Wright-Patterson AFB and the Full Military Retirement Exemption

Starting TY2024, Ohio fully exempts 100% of military retirement pay from state income tax, regardless of age or retirement amount. This is a significant recent change (previously Ohio taxed military retirement). Preparers with retired military clients must claim this subtraction on the IT 1040 or the client pays unnecessary Ohio tax.

Active duty pay is also exempt from Ohio income tax for Ohio residents stationed anywhere. Non-Ohio residents stationed in Ohio are exempt from Ohio tax on military pay under the Servicemembers Civil Relief Act.

WPAFB-specific carve-out: Ohio law provides that employees working at an Air Force base (including Wright-Patterson) are exempt from municipal income taxation by the city where the base is physically located. A civilian contractor or federal civil servant working at WPAFB owes municipal tax only to their HOME city, not to the city of the base location. This is frequently misunderstood and benefits WPAFB workers who live in lower-rate municipalities or municipalities with no income tax.

Military spouses: Under the Military Spouses Residency Relief Act, a spouse of a servicemember may maintain domicile in their home state even when living in Ohio due to PCS orders. A spouse domiciled in Florida living near WPAFB due to military orders may not owe Ohio income tax on wages if Florida domicile is properly maintained and documented. This is a high-value, rarely-served niche for preparers near military installations.

Ohio Income Tax Reciprocity Agreements

Ohio maintains income tax reciprocity agreements with five states: Indiana, Michigan, Kentucky, Pennsylvania, and West Virginia. Under these agreements, an Ohio resident who works in one of these states owes Ohio income tax on those wages (not the work state's income tax). An Indiana, Michigan, Kentucky, Pennsylvania, or West Virginia resident working in Ohio owes their home state tax only (not Ohio income tax).

Practical applications: A Covington, Kentucky resident working in Cincinnati owes only Kentucky income tax (not Ohio or Cincinnati municipal). A Youngstown-area resident who works across the Pennsylvania border in Mercer County, PA, owes only Ohio income tax on those wages. Municipal income tax is NOT covered by reciprocity agreements; municipal tax obligations for Ohio residents are determined by Ohio municipal rules regardless of where the work is performed within Ohio.
