Schedule 1-A and the OBBBA New Individual Deductions: A Practitioner Guide

Schedule 1-A is a new supplemental form attached to Form 1040. It reports the above-the-line deductions created by the OBBBA that were not previously part of the Form 1040 architecture: the qualified tip income deduction, the qualified overtime compensation deduction, the auto loan interest deduction, and the senior bonus deduction for taxpayers age 65 or older. None of these deductions existed under prior law. Each is a statutory creature of the OBBBA, each has its own eligibility criteria and phase-out structure, and each requires documentation that practitioners must collect before the October 15, 2026 extended return deadline.

This guide is written for enrolled agents, CPAs, and tax attorneys preparing individual returns for the 2025 and 2026 tax years. It covers the legal structure of each deduction, the documents needed to substantiate each, the W-2 coding changes that apply to 2026 wages, the 2025-vs.-2026 procedural differences that require separate client workflows, and the interactions with other tax provisions that create planning and compliance risk. All OBBBA provisions are recently enacted; verify all amounts, thresholds, and statutory citations at IRS.gov before use in client engagements. For the OBBBA changes to the Section 199A qualified business income deduction for pass-through entities, see the companion Section 199A QBI Deduction OBBBA Practitioner Guide.

All dollar amounts, thresholds, and statutory citations in this guide must be verified at IRS.gov before use in client engagements. OBBBA provisions are recently enacted; final regulations and form instructions govern. This guide is informational and does not constitute legal or tax advice.

Section 1: What Schedule 1-A Is and Where It Fits

Schedule 1-A is a new supplemental schedule attached to Form 1040. It is not a standalone form and is not filed independently. Its function is to aggregate and report the four new above-the-line deductions created by the OBBBA, which are then carried to Form 1040 and reduce adjusted gross income (AGI) in the same way as traditional above-the-line deductions such as the student loan interest deduction or the self-employed health insurance deduction.

Above-the-line treatment: benefits and limits

Because all four Schedule 1-A deductions are above-the-line, they are available to every eligible taxpayer regardless of whether the taxpayer itemizes or takes the standard deduction. A taxpayer who takes the standard deduction can still claim all four Schedule 1-A deductions for which they qualify. This is a significant structural difference from itemized deductions and is a key client communication point, particularly for the senior deduction and the auto loan interest deduction, where clients may assume they must itemize.

The above-the-line benefit has a corresponding limit: all four deductions phase out as modified adjusted gross income (MAGI) rises above the IRS.gov-published thresholds. The phase-out is not a cliff; it is a gradual reduction. Each provision has its own phase-out range, and the four ranges do not run together. A taxpayer with high MAGI may retain a partial deduction for one provision while losing another entirely. Verify all current phase-out thresholds and ranges at IRS.gov; recently enacted.

Section 2: Qualified Tip Income Deduction (OBBBA Section 70201 / Notice 2025-71)

Who qualifies

The deduction is available to employees and self-employed workers who receive tips in a qualifying occupation. The IRS published the list of qualifying occupations in Notice 2025-71. Practitioners must verify each client's occupation against that list before claiming the deduction. The Notice list is the controlling authority; a client's subjective belief that their occupation qualifies is not sufficient. Occupations that commonly appear in a tipping context but are not on the Notice 2025-71 list do not qualify.

Monitor IRS.gov for any updates to Notice 2025-71 or supplementary guidance on occupation eligibility. The Notice was published in 2025; additional occupations or clarifications may be added before the October 15, 2026 production deadline.

What counts as a qualifying tip

A qualifying tip is a discretionary amount given by a customer directly to the employee or self-employed worker. The critical qualifier is "discretionary." A service charge added by the employer and distributed to employees is not a tip under this provision; it is a wage. Service charges are wages regardless of whether the employer labels them as tips or gratuities on the receipt. The deduction applies to the gross tip amount; it is not reduced by the FICA tax paid on those tips (the employer FICA credit under IRC Section 45B is a separate provision discussed in Section 8 of this guide).

Phase-out by MAGI

The qualified tip income deduction phases out as MAGI rises above the IRS.gov-published threshold. The specific phase-out starting point and phase-out range: verify current figures at IRS.gov before computing the deduction for any client. The phase-out applies separately from the phase-outs for the other three Schedule 1-A provisions. A taxpayer with MAGI above the tip deduction phase-out threshold may still have partial or full deductions available under the other provisions.

2025 vs. 2026 documentation: the W-2 Code TP difference

The documentation requirement for the qualified tip income deduction differs between the 2025 and 2026 tax years. W-2 Box 12 Code TP applies only to wages paid on or after January 1, 2026. It does not exist on 2025 W-2s.

For 2025 returns: the deduction is self-reported. Practitioners must rely on client records, including Form 4070 (Employee's Report of Tips to Employer) and Form 4070-A (Employee's Daily Record of Tips), pay stubs showing reported tip amounts, employer tip reporting statements, and any other contemporaneous documentation. IRS substantiation guidance for 2025 tip deductions is pending as of July 2026. Monitor IRS.gov for that guidance before finalizing any 2025 return claiming this deduction.

For 2026 returns: employers are required to report qualifying tip amounts in W-2 Box 12 using Code TP. The IRS is expected to match Schedule 1-A reported tip deductions against Code TP W-2 amounts. The W-2 Code TP amount becomes the primary verification mechanism, and discrepancies between the Schedule 1-A deduction and the Code TP amount will likely generate IRS matching inquiries.

Self-employed tip recipients

Self-employed workers in qualifying occupations (for example, a self-employed hairstylist or massage therapist in an occupation on the Notice 2025-71 list) may also claim the qualified tip income deduction. For self-employed workers, qualifying tip income is reflected in Schedule C gross receipts from the tipping environment. The practitioner should advise these clients to maintain a contemporaneous tip log segregating tip receipts from non-tip service revenue. The gross tip amount reported on Schedule 1-A reduces income tax but does not reduce the self-employment tax base; see Section 8 of this guide for that interaction.

Section 3: Qualified Overtime Compensation Deduction (OBBBA Section 70202 / Notice 2025-69)

The qualified overtime compensation deduction is available to employees who receive overtime pay that meets the definition of "qualified overtime" under the Fair Labor Standards Act (FLSA) as interpreted by IRS Notice 2025-69. The FLSA definition is the controlling standard. Not all overtime pay is qualified overtime under this provision, and the exclusions are significant.

What constitutes "qualified overtime" under the FLSA

Under the FLSA, an employer is required to pay a non-exempt employee at a rate of at least one and one-half times the employee's regular rate for all hours worked in excess of 40 in a workweek. "Qualified overtime" for purposes of the OBBBA deduction is overtime pay meeting this FLSA standard: hours worked beyond 40 per workweek, in an FLSA-covered employer-employee relationship, paid at the legally required overtime rate.

What does NOT qualify: the four exclusions practitioners must communicate

Phase-out by MAGI

The qualified overtime compensation deduction phases out as MAGI rises above the IRS.gov-published threshold. Verify the specific phase-out starting point and range at IRS.gov. The overtime phase-out and the tip income phase-out operate separately; the thresholds may differ, and each is calculated independently.

2025 vs. 2026 documentation: W-2 Code TT

W-2 Box 12 Code TT (qualified overtime) applies only to wages paid on or after January 1, 2026. It does not exist on 2025 W-2s. For 2025 returns, the deduction is self-reported. Practitioners must collect pay stubs identifying overtime hours and overtime pay, and the IRS may require an employer certification confirming that the overtime was FLSA-triggered. IRS substantiation guidance for 2025 overtime deductions is pending as of July 2026; monitor IRS.gov.

For 2026 returns, employers report qualifying overtime compensation in W-2 Box 12 using Code TT. As with Code TP, the IRS is expected to match Schedule 1-A reported overtime deductions against Code TT W-2 amounts. Alert clients that pay stubs alone are not sufficient for 2026 returns if the W-2 Code TT amount is present; the Code TT amount controls.

Self-employed: no overtime deduction available

The qualified overtime compensation deduction is not available to self-employed individuals, independent contractors, or sole proprietors. The FLSA definition requires an employer-employee relationship. A self-employed person has no employer and therefore cannot receive FLSA-qualified overtime. There is no self-employed equivalent of this deduction. Do not attempt to claim overtime deductions on Schedule 1-A for clients filing Schedule C.

Dual-income households: no pooling between spouses

For married filing jointly (MFJ) returns, each spouse's qualified overtime compensation is calculated separately. The deduction is not pooled across spouses. If one spouse has qualifying overtime and the other does not, only the qualifying spouse's overtime amount goes on Schedule 1-A. The MFJ filing status does not permit one spouse's overtime to flow through to the other, and it does not change the MAGI phase-out thresholds for individual provisions.

Section 4: Auto Loan Interest Deduction

The OBBBA created an above-the-line deduction for interest paid on loans used to purchase a new vehicle after the OBBBA effective date. All dollar limits on the deductible interest amount per year: verify current figures at IRS.gov. The provision is subject to a MAGI-based phase-out; verify the phase-out threshold and range at IRS.gov before computing any client's deduction.

Three hard eligibility gates

Before reaching the phase-out analysis, the vehicle and the financing arrangement must clear three eligibility gates. All three must be satisfied; failing any one of them means the interest is not deductible on Schedule 1-A.

1. New vehicle, not a lease. The deduction applies to a new vehicle purchased outright (via a loan). Lease payments are not loan interest and do not qualify. The vehicle must be new; used vehicles do not qualify regardless of when they were purchased or when the loan was originated.
2. Purchased after the OBBBA effective date. Vehicles purchased before the OBBBA effective date do not qualify, even if the loan was still outstanding when the OBBBA was enacted. Verify the controlling effective date at IRS.gov; recently enacted.
3. Primarily personal use. The deduction on Schedule 1-A applies to the personal-use portion of the vehicle. If the vehicle is used for both personal and business purposes, the interest must be allocated between personal use (Schedule 1-A) and business use (Schedule C, Schedule E, or the applicable business form). The business-use portion does not go on Schedule 1-A; it follows the applicable business deduction rules on the other schedule.

Documentation: Form 1098 equivalent

IRS guidance on the specific form or statement lenders must provide for auto loan interest under this provision is forthcoming as of July 2026. Advise clients to retain all loan origination documents, monthly loan statements showing interest paid, and any IRS-prescribed form the lender issues. Do not finalize a return claiming this deduction without confirming the substantiation standard at IRS.gov; recently enacted, and lender reporting requirements have not yet been finalized.

Section 5: Senior Bonus Deduction (Age 65 or Older)

The OBBBA created a fixed-dollar above-the-line deduction for taxpayers who are age 65 or older as of the last day of the tax year. The specific dollar amount per qualifying taxpayer: verify current figures at IRS.gov. The deduction is per qualifying person, not per return. On an MFJ return where both spouses are 65 or older, both spouses may each claim the deduction separately, subject to each spouse satisfying the eligibility criteria.

Eligibility criteria

• Age 65 or older as of the last day of the tax year. A taxpayer who turns 65 on January 1 of the following year does not qualify for the prior tax year.
• Not a dependent of another taxpayer. A taxpayer who can be claimed as a dependent on another person's return (even if not actually claimed) does not qualify for the senior deduction.

Phase-out by MAGI

The senior deduction phases out as MAGI rises above the IRS.gov-published threshold. The phase-out applies per qualifying taxpayer. Verify the threshold and phase-out range at IRS.gov; recently enacted. The senior deduction phase-out operates independently from the phase-outs for the other three Schedule 1-A provisions.

Interaction with the additional standard deduction for age 65

The senior deduction on Schedule 1-A is entirely separate from and additive with the additional standard deduction for age 65 that is already built into Form 1040. A taxpayer who is 65 or older and takes the standard deduction can claim both: the additional standard deduction amount built into their standard deduction calculation and the separate Schedule 1-A senior bonus deduction. These are not alternatives to each other; both can be claimed in the same tax year by an eligible taxpayer. This is an important client communication point because many clients and some practitioners incorrectly assume the two provisions offset or replace each other.

Section 6: Phase-Out Mechanics and Stacking

All four Schedule 1-A deductions phase out as MAGI rises above the IRS.gov-published thresholds. Three structural rules govern how the phase-outs interact.

Each provision has its own phase-out range

The four provisions do not share a single unified phase-out. Each has its own threshold and phase-out range, which may differ from the others. A practitioner cannot assume that a taxpayer's MAGI relative to one provision's threshold predicts the result for another provision. Every provision must be evaluated separately against its own IRS.gov-published threshold. Verify all four phase-out ranges independently at IRS.gov before completing any Schedule 1-A calculation.

IRS worksheets and updated software are required

Practitioners cannot accurately compute the total Schedule 1-A deduction without either the IRS worksheets included in the final Schedule 1-A instructions or tax software that has been updated to reflect published IRS.gov guidance on the phase-out thresholds and ranges. The March 2026 draft form does not include finalized worksheets. Before completing any Schedule 1-A, confirm that the software version in use has been updated with the final IRS.gov guidance. Confirm this with the software vendor, not by visual inspection of the software.

MAGI for Schedule 1-A may differ from MAGI for other provisions

MAGI is not a single universal figure. Different Code provisions define MAGI differently, by specifying which items are added back to or subtracted from AGI in the calculation. The MAGI definition for Schedule 1-A phase-out purposes may differ from MAGI as defined for the Roth IRA contribution limit, the premium tax credit, the student loan interest deduction, or other provisions. Do not cross-apply MAGI computed for one provision to the Schedule 1-A phase-out without verifying that the definitions are identical. Await IRS.gov guidance on the specific MAGI definition applicable to each of the four Schedule 1-A provisions; recently enacted, and the definition may vary by provision.

Section 7: 2025 vs. 2026 Return Differences

The procedural requirements for Schedule 1-A differ materially between 2025 and 2026 tax year returns. The critical difference is the W-2 coding system: Code TP and Code TT do not exist on 2025 W-2s. This creates a two-track documentation requirement that practitioners must manage simultaneously if they are completing both 2025 extended returns and early 2026 returns in the same production window.

2025 returns: self-reported deductions, no W-2 code verification

For the 2025 tax year, the W-2 Box 12 codes TP and TT did not exist. Employers were not required to separately identify qualifying tip and overtime amounts in W-2 Box 12. All Schedule 1-A deductions on 2025 returns must be substantiated entirely by client records. The burden of proof is on the practitioner and client to document the qualifying nature of the amounts claimed.

Required records for 2025 tip deductions: Form 4070, Form 4070-A, pay stubs showing allocated tips, and contemporaneous tip logs. Required records for 2025 overtime deductions: pay stubs identifying overtime hours and pay; the IRS may require employer certification confirming FLSA qualification. IRS guidance on 2025 substantiation requirements is pending as of July 2026. Do not file 2025 returns with Schedule 1-A deductions without confirming the current substantiation standard at IRS.gov.

2026 returns: W-2 Box 12 Codes TP and TT are the verification mechanism

For wages paid on or after January 1, 2026, employers are required to report qualifying tip amounts in W-2 Box 12 using Code TP and qualifying overtime amounts using Code TT. For 2026 returns, the IRS is expected to match Schedule 1-A reported amounts against the employer-reported W-2 Box 12 codes. A discrepancy between a Schedule 1-A claimed deduction and the corresponding W-2 Box 12 code amount will likely generate IRS matching inquiries or adjustments.

Practitioners completing 2026 returns should pull the W-2 Box 12 amounts for Codes TP and TT from every employer W-2 before completing Schedule 1-A, and should not accept client-stated amounts that exceed the Code TP or Code TT amounts on the employer W-2 without IRS-published guidance authorizing supplemental documentation. Alert clients that if their employer did not use Code TP or TT when it was required, the client may need to pursue a corrected W-2 (Form W-2c) before the return can be completed accurately.

October 15, 2026: the production deadline for extended returns

October 15, 2026 is the extended individual return deadline. For practitioners with extended 2025 returns that include Schedule 1-A deductions, this date is the hard production deadline. IRS guidance on 2025 substantiation, final Schedule 1-A instructions, and confirmed phase-out thresholds are all expected to be published by IRS.gov before this date. Build the client file now: collect tip logs, overtime records, pay stubs, and employer certification letters. Do not wait for final IRS guidance before collecting documentation; IRS guidance will tell you what the standard is, but the documentation itself must come from the client's contemporaneous records.

Section 8: Interaction with Other Provisions

Tips and FICA employer credit (IRC Section 45B)

The IRC Section 45B employer credit for FICA taxes paid on employee tips is a separate provision from the employee's qualified tip income deduction on Schedule 1-A. The two provisions can coexist. The employer claims the Section 45B credit on the employer's return. The employee claims the tip income deduction on Schedule 1-A. The employee deduction is not reduced by the amount of FICA taxes paid on those tips, and the employer credit is not affected by whether the employee claims the deduction. Practitioners representing food and beverage employers should maintain this distinction clearly: the employer-side credit and the employee-side deduction are separate; each is claimed on a different return by a different party. For payroll tax compliance and employer-side FICA reporting obligations, see our Payroll Tax Compliance: Form 941, Deposit Schedule, and IRC Section 6656 Guide.

Overtime and qualified business income (QBI): S-corp owner-employee considerations

For an S-corp owner who is also a W-2 employee of the corporation, overtime pay received from the S-corp that meets the FLSA definition is deductible on Schedule 1-A. However, the amount and characterization of compensation paid by an S-corp to its shareholder-employee directly affects the reasonable compensation analysis and the Section 199A QBI calculation. A large overtime payment to an owner-employee increases the W-2 wage pool (affecting the Section 199A W-2 wage limitation) while reducing entity-level income and therefore QBI. Practitioners must model both effects simultaneously and should flag S-corp owner-employee overtime situations for the reasonable compensation analysis. For a full treatment of the QBI and reasonable compensation interaction, see our Section 199A QBI Deduction OBBBA Practitioner Guide.

Tips and self-employment tax

For self-employed tip recipients (for example, a self-employed aesthetician or independent hair stylist in a qualifying occupation), the qualified tip income deduction on Schedule 1-A reduces income tax liability but does NOT reduce the self-employment (SE) tax base. SE tax is computed on net self-employment income before the above-the-line deductions on Schedule 1-A are applied. This means that a self-employed client whose entire qualifying tip income is deducted on Schedule 1-A still owes SE tax on the underlying tip income. Communicate this result clearly: the deduction is not "tax-free" for SE tax purposes, only for income tax purposes.

Senior deduction and the additional standard deduction: additive, not alternative

As noted in Section 5, the Schedule 1-A senior bonus deduction and the additional standard deduction available to taxpayers age 65 or older are two separate provisions that can both be claimed in the same year by an eligible taxpayer. The additional standard deduction is a fixed add-on to the standard deduction figure for taxpayers who do not itemize (and also factors into the itemized deduction analysis for those who do). The Schedule 1-A senior bonus deduction is an above-the-line deduction that reduces AGI. Both can be claimed simultaneously; they are additive.

Section 9: Practitioner Workflow and Client Checklist

Use this checklist on every individual return before closing the Schedule 1-A analysis. Each item should be confirmed and documented in the client file. The October 15, 2026 extended deadline is the production deadline for all 2025 extended returns with Schedule 1-A deductions.

Step 1: Identify applicable provisions

• Did the client receive tips in 2025 or 2026 in a qualifying occupation? Pull the Notice 2025-71 occupation list and verify. If yes: qualified tip income deduction may apply (Schedule 1-A line 1, per March 2026 draft).
• Did the client receive overtime pay as a non-exempt employee from an employer in 2025 or 2026? Was the overtime FLSA-triggered (more than 40 hours in a workweek)? If yes: qualified overtime compensation deduction may apply (Schedule 1-A line 2, per March 2026 draft).
• Did the client purchase a new vehicle (not a lease) after the OBBBA effective date and finance it with a loan? If yes: auto loan interest deduction may apply (Schedule 1-A line 3, per March 2026 draft).
• Was the client age 65 or older as of December 31 of the tax year? Is the client not a dependent of another taxpayer? If yes: senior bonus deduction may apply (Schedule 1-A line 4, per March 2026 draft).

Step 2: Pull Notice 2025-71 for tip clients

• Obtain the current Notice 2025-71 occupation eligibility list from IRS.gov. Do not rely on memory or prior-year materials; confirm the current list directly from IRS.gov.
• Match the client's specific occupation (by job title and industry, not just self-description) against the Notice 2025-71 list. Document the match in the client file.
• If the client worked in a qualifying occupation for only part of the year, identify the qualifying and non-qualifying periods and apportion tip income accordingly.
• Confirm that the amounts claimed are discretionary customer tips, not employer-added service charges classified as wages.

Step 3: Document tip and overtime amounts for 2025 (pre-W-2-code era)

• For tips: collect Form 4070, Form 4070-A, and any employer tip reporting statements. Obtain the client's contemporaneous tip log if available.
• For overtime: collect pay stubs or payroll summaries identifying FLSA-triggered overtime hours and pay amounts. Obtain employer certification of FLSA status if required per IRS.gov guidance (forthcoming).
• Monitor IRS.gov for 2025 substantiation guidance before finalizing any 2025 return. Do not file without confirming the current substantiation standard.

Step 4: Alert clients about the October 15, 2026 deadline and software readiness

• Communicate to every client with extended 2025 returns that October 15, 2026 is the hard deadline. Schedule 1-A deductions cannot be finalized without confirmed IRS.gov thresholds and final instructions; build the documentation file now so the return can be completed quickly once final guidance is published.
• Confirm with your tax software vendor that the software has been updated to reflect final IRS.gov guidance on Schedule 1-A, including the phase-out worksheets and the current threshold figures. Do not use software that reflects only the March 2026 draft without vendor confirmation of updates for final IRS guidance.
• For 2026 returns (early filers): collect W-2 Box 12 Codes TP and TT from every employer W-2 before completing Schedule 1-A. If a Code is missing where expected, advise the client to obtain a corrected W-2 (Form W-2c) from the employer.
