Iowa sits in an unusual position among states: it imposes no license or registration requirement on paid tax preparers, yet it does mandate continuing education and PTIN reporting for preparers who handle 10 or more Iowa returns per year. The state also completed a major tax reform cycle with a 3.8% flat rate taking effect in TY2025, a full repeal of the Iowa Inheritance Tax beginning January 1, 2025, and a significant standard deduction shift in TY2026. For preparers working in Iowa, the practical complexity is concentrated in three areas: the unique CE reporting obligation under Iowa Code sections 421.62 through 421.64, the farmland capital gains deduction available to agricultural clients, and the broad retirement income exemptions that create significant planning value for Iowa retirees. This guide covers every requirement Iowa paid preparers need to know for TY2025 returns filed in 2026.
Does Iowa Require a State Tax Preparer License?
Iowa has NO state license or registration requirement for non-credentialed paid tax preparers. There is no exam to pass, no surety bond to post, and no registration with the Iowa Department of Revenue before you can begin preparing returns for pay.
However, Iowa is unique among states without formal licensure. Under Iowa Code sections 421.62 through 421.64 (effective January 1, 2020), any paid preparer who completes 10 or more Iowa individual income tax returns for compensation in a calendar year is subject to a mandatory compliance framework. CPAs, attorneys, and Enrolled Agents are fully exempt from these obligations.
PTIN Requirement: Required on All Iowa Returns
A valid federal PTIN is required on every Iowa return you prepare for compensation. This includes IA 1040, IA 1041, IA 1120, IA 1120S, and IA 1065. The PTIN must be current for the filing year.
Penalty for PTIN omission: $50 per return, capped at $25,000 per calendar year. The Iowa Department of Revenue enforces this independently of IRS penalties.
Continuing Education: 15 Hours Per Year
Preparers subject to Iowa Code sections 421.62 through 421.64 must complete a minimum of 15 hours of continuing education annually from IRS-approved CE providers. At least 2 of those 15 hours must be devoted to ethics.
This is a standalone Iowa requirement, separate from the 18-hour Annual Filing Season Program (AFSP). Completing the AFSP satisfies the 15-hour Iowa requirement (18 hours exceeds the 15-hour floor), but the Iowa CE obligation does not confer AFSP status on its own.
Form 78-012: Annual CE Reporting Obligation
After completing the required CE, Iowa preparers must file Form 78-012 with the Iowa Department of Revenue via GovConnectIowa. This form reports CE completion for the prior calendar year and is due by February 15 of the following year.
- Filing portal: GovConnectIowa (govconnect.iowa.gov)
- Deadline: February 15 of the year following the CE completion year
- CE records must be retained for 5 years
- First violation: written warning from Iowa DOR
- Repeated violations: suspension from preparing Iowa returns
Who Is Exempt
CPAs licensed under Iowa Code chapter 542, attorneys admitted to the Iowa bar, and Enrolled Agents licensed by the IRS are fully exempt from Iowa Code sections 421.62 through 421.64. Their professional licensing and CE requirements are governed separately.
PTIN and EFIN: Federal Requirements Apply
PTIN 2026 renewal fee: $18.75 ($10.00 IRS base fee plus $8.75 third-party contractor fee). Renew annually by December 31 at irs.gov/ptin. EFIN is required if you plan to e-file Iowa returns. Iowa participates in the IRS Fed/State e-File program; no separate state EFIN is issued.
FTC Safeguards Rule (WISP)
Every paid tax preparer, including solo practitioners, must maintain a Written Information Security Plan (WISP) under the Gramm-Leach-Bliley Act (15 U.S.C. 6801(b)). Required elements include a designated responsible individual, multi-factor authentication for all systems containing client data, a written risk assessment, and an incident response plan. FTC penalties reach up to $46,517 per violation per day. Free WISP template available at IRS Publication 5708.
Iowa Individual Income Tax for TY2025 and TY2026
Flat Rate: 3.8% for TY2025
Iowa taxes all net income at a flat 3.8% for Tax Year 2025. Iowa uses federal taxable income (not federal AGI) as the starting point, then applies Iowa-specific additions and subtractions via Iowa Schedule 1. No further enacted rate reduction below 3.8% has been signed into law as of this writing.
Standard Deduction: Significant Change in TY2026
Iowa uses its own standard deduction amounts for TY2025, then transitions to conformity with federal standard deduction amounts beginning TY2026. This is a substantial change that will affect virtually every non-itemizing Iowa filer.
| Filing Status | TY2025 (Iowa-specific) | TY2026 (Federal conformity) |
|---|---|---|
| Single | $2,130 | $16,100 |
| Married Filing Jointly | $5,240 | $32,200 |
The jump from Iowa's own standard deduction to the federal amounts is dramatic, particularly for married filers ($5,240 to $32,200). For TY2026 returns, many Iowa filers who previously itemized will find the higher standard deduction eliminates their Iowa itemized deduction advantage.
Federal Income Tax Deductibility: Eliminated
Iowa no longer allows a subtraction for federal income taxes paid. This deduction was phased out as part of Iowa's tax reform package. Do not claim federal taxes paid as a deduction on the Iowa return.
Social Security: Fully Exempt
Social Security benefits are fully exempt from Iowa income tax at all income levels. There is no income threshold or phase-out. A retiree with $200,000 in other income and $40,000 in Social Security pays zero Iowa tax on the Social Security portion.
Military Retirement: Fully Exempt
All military retirement pay is fully exempt from Iowa income tax under Iowa Admin Code 701-302.80. This applies to retirement pay from all military branches regardless of the retiree's age or total income.
Retirement Income: Fully Exempt at Age 55 and Older
Iowa House File 2317 (effective TY2023) provides a full exemption for qualifying retirement income for taxpayers age 55 and older. Qualifying plans include 401(k) and 403(b) distributions, IRA distributions, pension income, and annuity income from qualified retirement plans.
Combined with the full Social Security exemption and the full military retirement exemption, Iowa retirees age 55 and older commonly owe little or no Iowa income tax. Positioning clients correctly in their first retirement year is a high-value planning service.
Iowa Earned Income Tax Credit: 15% of Federal, Fully Refundable
Iowa offers a state EITC equal to 15% of the federal Earned Income Tax Credit, and it is fully refundable. A taxpayer who qualifies for the federal EITC automatically qualifies for the Iowa credit. Because it is refundable, the Iowa EITC can generate a refund even when Iowa tax liability is zero. Federal EITC eligibility requires a valid Social Security number; the same SSN requirement applies to the Iowa credit.
Capital Gains: Flat Rate with Farmland Deduction Exception
Capital gains are taxed at the standard 3.8% flat rate in Iowa. However, Iowa provides the Iowa Capital Gain Deduction for qualifying gains on the sale of farmland and certain other assets. Qualifying gains may be fully excluded from Iowa taxable income.
Farmland qualifying criteria:
- The property must have been held for 10 or more years
- The seller must have materially participated in farming operations during the holding period
- A retired farmer exception applies at age 55 and older, relaxing the material participation requirement
- IA 100 series forms (IA 100A through IA 100J) are required to document the deduction
Iowa State University's Center for Agricultural Law and Taxation (CALT) at calt.iastate.edu is the authoritative resource for practitioners navigating farmland capital gain deduction eligibility. This is the single most complex and high-value area of Iowa individual income tax practice.
Iowa Inheritance Tax: Fully Repealed as of January 1, 2025
Iowa's inheritance tax was fully repealed effective January 1, 2025. Estates of decedents who died on or after that date owe no Iowa inheritance tax. This significantly simplifies estate planning and elder planning work for Iowa clients. Estates of decedents who died before January 1, 2025 may still require Iowa inheritance tax filings under prior law.
Iowa Federal Conformity and OBBBA Provisions
Iowa conforms to the Internal Revenue Code on a rolling basis, meaning it automatically adopts federal law changes as they are enacted unless Iowa specifically decouples. Iowa conforms to the One Big Beautiful Budget Act (OBBBA) provisions for TY2025 through TY2028.
OBBBA Provisions Applicable in Iowa
- Tips deduction: Up to $25,000 of tip income may be deducted
- Overtime compensation deduction: Up to $12,500 (single) or $25,000 (MFJ)
- Car loan interest deduction: Interest on qualifying vehicle loans is deductible
- Section 179 expensing and bonus depreciation: Full conformity for TY2020 forward
Unlike South Carolina, which decoupled from OBBBA and requires add-backs, Iowa preparers apply these deductions on both the federal and Iowa return without adjustment. No Iowa-specific add-back is required for OBBBA items.
Local Taxes in Iowa: No City or County Income Tax
Iowa cities and counties do NOT impose local income taxes. All Iowa income taxation is at the state level. This simplifies return preparation compared to states like Ohio and Pennsylvania that layer local earned income taxes on top of state returns.
However, Iowa clients may be subject to school district surtaxes and emergency medical services (EMS) surtaxes. These are assessed as a percentage of Iowa income tax liability (not of income directly) and vary by county. They appear on IA 1040 Lines 20 and 22. To calculate them correctly, you must look up the client's school district code. Rates and applicable districts are published by the Iowa Department of Revenue each year.
These surtaxes are often overlooked by preparers new to Iowa returns. Always verify the client's school district code, particularly when they have moved during the year or own property in a different county than their residence.
Iowa E-File Requirement
Iowa has NO state-level mandatory e-file requirement for individual return preparers. There is no Iowa threshold (such as a 100-return rule) that triggers an obligation to e-file Iowa individual income tax returns.
The federal IRS e-file mandate applies independently: preparers who file 11 or more federal individual income tax returns per year must e-file all federal returns. Iowa participates in the IRS Fed/State e-File program, so e-filing the federal return simultaneously transmits the Iowa return. No separate Iowa EFIN is required.
While e-filing is not mandated at the state level, the Iowa Department of Revenue strongly encourages it. Iowa e-file acceptance is immediate; paper return processing can take 8 to 12 weeks during peak season.
Starting a Tax Preparation Business in Iowa
LLC Formation
Iowa LLCs are registered with the Iowa Secretary of State. Formation is straightforward and inexpensive.
- Articles of Organization filing fee: $50
- Biennial report: $30 online / $45 paper (filed in odd-numbered years)
- Franchise tax: None
Iowa's low formation cost and absence of a franchise tax make it an economical state in which to form a business entity. The biennial report is due in odd years (2025, 2027, etc.) and keeps the LLC in good standing with the Secretary of State.
Sales Tax on Tax Preparation Services
Tax preparation services are NOT taxable services in Iowa. Preparers do not collect or remit Iowa sales tax on their preparation fees. This is a clear-cut exemption, unlike some other states where the treatment of professional services is ambiguous.
Local Business Licenses
Iowa has no statewide business license requirement. Certain cities may require a local business license; check with your specific city or county. Des Moines, Cedar Rapids, and Davenport each have their own business registration processes. Confirm requirements with the relevant city before opening a physical office location.
High-Value Client Niches in Iowa
Agricultural Clients and Farmland Capital Gains
The Iowa Capital Gain Deduction on qualifying farmland sales is the most complex and highest-value area of Iowa individual income tax practice. A qualifying sale can entirely eliminate Iowa tax liability on what might be a seven-figure gain. The 10-year hold requirement, material participation documentation, and the retired farmer exception at age 55 require careful analysis. Errors here carry significant consequences for clients.
Iowa State University's Center for Agricultural Law and Taxation (CALT at calt.iastate.edu) publishes practitioner guides, webinars, and analysis on farmland tax issues. If you serve agricultural clients, CALT resources are essential. The IA 100A through 100J form series documents each qualification test for the deduction.
Retirement Income Planning
The combination of full retirement income exemption (age 55 and older), full Social Security exemption (all income levels), and full military retirement exemption means many Iowa retirees owe minimal or zero state income tax. Positioning clients correctly in their first year of retirement is high-value work: the year a client turns 55 or retires, correctly applying these exemptions can eliminate the entire Iowa tax bill. Retirees relocating to Iowa from higher-tax states benefit significantly.
Estate and Elder Planning After the Inheritance Tax Repeal
The full repeal of Iowa's inheritance tax effective January 1, 2025 simplifies estate planning for Iowa clients considerably. Estates of decedents dying after that date owe no Iowa inheritance tax regardless of relationship or estate size. For preparers handling estate returns or advising clients on elder planning, this eliminates a significant compliance burden and makes Iowa among the most favorable states for wealth transfer. Clients who had old estate plans structured partly around the Iowa inheritance tax may benefit from a review.
Military Community (Camp Dodge Area)
Camp Dodge, located in Johnston near Des Moines, is the headquarters of the Iowa Army National Guard and a major training installation. Military retirees in this community benefit from full exemption of military retirement pay, full Social Security exemption, and MSRRA (Military Spouses Residency Relief Act) protection for qualifying spouses who work in Iowa while maintaining residency in another state. These clients have significant tax planning value.
Insurance Industry (Des Moines)
Des Moines is one of the largest insurance hubs in the United States, home to Principal Financial Group, Nationwide, EMC Insurance, and dozens of regional carriers. Employees of these firms often have complex returns: RSU vesting events, non-qualified stock option exercises, deferred compensation plans, and multi-state returns for employees who work remotely or maintain licenses in multiple states. This is a higher-revenue client segment with above-average return complexity.
Immigrant and ITIN-Filer Communities
Iowa's meatpacking industry has created substantial immigrant communities in cities including Waterloo, Storm Lake, and Columbus Junction. ITIN filers do not qualify for the state or federal EITC (SSN required for both), but they may still owe or receive Iowa refunds from withholding on Iowa-source wages. Bilingual preparation services (English/Spanish, English/Burmese, English/Arabic depending on local community composition) represent a significant and underserved market in these areas.
Iowa CE Requirement: Practical Checklist
Iowa's CE and reporting requirement (Iowa Code sections 421.62 through 421.64) applies to any preparer who completes 10 or more Iowa returns for pay in a calendar year. The following checklist covers all compliance steps for a typical Iowa preparer.
Compliance Checklist
- Count your Iowa returns: If you prepare 10 or more Iowa individual income tax returns for compensation in a calendar year, this requirement applies to you
- Earn 15 CE hours: Complete a minimum of 15 hours from an IRS-approved CE provider during the calendar year
- Satisfy the ethics requirement: At least 2 of the 15 hours must be ethics
- Use IRS-approved providers: All 15 hours must come from providers approved by the IRS Office of Professional Responsibility
- AFSP qualifies: Completing the 18-hour AFSP satisfies the Iowa 15-hour requirement and earns the AFSP Record of Completion
- File Form 78-012 by February 15: Report CE completion via GovConnectIowa before February 15 of the year following the CE year
- Retain CE records for 5 years: Keep certificates of completion and provider documentation
Iowa CE Resources
Several organizations offer CE that qualifies for Iowa's requirement:
- Americas Tax Professionals (americastax.com): IRS-approved CE provider (P619F), including AFSP-qualifying courses that satisfy Iowa's 15-hour requirement
- NATP Iowa Chapter (natptax.com): National Association of Tax Professionals; active Iowa chapter with state-specific CE calendar
- AAI (aaiiowa.com): Accountants and Tax Advisors of Iowa; local CE events and resources
- Iowa State University CALT (calt.iastate.edu): Agricultural tax CE, highly recommended for preparers with farming clients
Sanctions for Non-Compliance
The Iowa Department of Revenue applies a progressive sanction structure:
- First violation: written warning
- Repeated violations: suspension from preparing Iowa returns
- PTIN omission: $50 per return, capped at $25,000 per calendar year

Frequently Asked Questions
Does Iowa require a tax preparer license?
No state license is required. However, preparers completing 10 or more Iowa returns for pay must hold a valid federal PTIN, complete 15 hours of CE annually from an IRS-approved provider (at least 2 hours ethics), and file Form 78-012 with the Iowa Department of Revenue via GovConnectIowa by February 15 of the following year. CPAs, attorneys, and Enrolled Agents are exempt from these requirements.
What is Iowa's income tax rate for 2025?
Iowa taxes income at a flat 3.8% for tax year 2025. This applies to all taxable income after Iowa-specific deductions. Iowa starts the calculation from federal taxable income, then applies Iowa Schedule 1 modifications for additions and subtractions specific to Iowa law.
How many returns trigger Iowa's e-file requirement?
Iowa has no state-level e-file mandate for individual return preparers. There is no Iowa return-count threshold that requires state e-filing. The federal IRS e-file mandate (11 or more federal returns per year) still applies, and Iowa participates in the Fed/State e-File program so those returns are transmitted simultaneously.
Is Social Security income taxable in Iowa?
No. Social Security benefits are fully exempt from Iowa income tax at all income levels. There is no income phase-out or threshold. This exemption applies in addition to the full retirement income exemption for taxpayers age 55 and older, and the full military retirement exemption.
How much does it cost to start a tax prep LLC in Iowa?
LLC formation with the Iowa Secretary of State costs $50. There is no franchise tax in Iowa. A biennial report costs $30 online (due in odd-numbered years). Tax preparation services are not subject to Iowa sales tax, so no sales tax collection or remittance is required on preparation fees.
What is Iowa's capital gains tax rate on farmland?
Iowa farmland gains that meet the qualifying criteria may be entirely excluded under the Iowa Capital Gain Deduction. Requirements include a 10-year hold and material participation in farming operations; a retired farmer exception applies at age 55 and older. Gains that do not qualify for the deduction are taxed at the standard 3.8% flat rate. The IA 100 series forms document the deduction. Iowa State University's Center for Agricultural Law and Taxation (calt.iastate.edu) is the authoritative practitioner resource for farmland capital gain issues.
For 2025 returns, verify how this state responds to the One Big Beautiful Bill Act provisions before filing. The state OBBBA conformity practitioner guide covers the conformity analysis workflow for tip and overtime income add-backs, bonus depreciation decoupling, and QBI adjustments in major nonconforming states.
