Schedule 1-A: How to Use the New IRS Form for Tips, Overtime, Car Loans, Seniors

Tax information is for educational purposes only and does not constitute tax advice. Consult a licensed tax professional for your specific situation.

The One Big Beautiful Bill introduced several new above-the-line deductions and exclusions that did not fit neatly onto existing IRS forms. In response, the IRS created Schedule 1-A, a new attachment to Form 1040 designed specifically to capture the no-tax-on-tips exclusion, the no-tax-on-overtime exclusion, the car loan interest deduction, and the enhanced senior standard deduction. If you qualify for any of these provisions, you will need to complete Schedule 1-A and attach it to your federal return starting with the 2026 tax year.

This guide provides a line-by-line walkthrough of the form, explains who needs to file it, and shows how the numbers flow to your Form 1040.

Who Needs to File Schedule 1-A?

Schedule 1-A is required if you claim any of the following new provisions for the 2026 tax year or later:

No Tax on Tips — You received tip income and want to exclude qualifying tips from federal income tax
No Tax on Overtime — You earned overtime pay and want to exclude qualifying overtime compensation from federal income tax
Car Loan Interest Deduction — You paid interest on a qualifying auto loan and want to deduct it
Senior Standard Deduction Enhancement ($6,000) — You are age 65 or older and want to claim the additional ~$6,000 standard deduction created by the OBBB

If none of these apply to you, you do not need to file Schedule 1-A. Your return will follow the traditional form flow using Schedule 1 (if applicable) and the standard Form 1040.

How Schedule 1-A Connects to Form 1040

Schedule 1-A feeds into Form 1040 at two key points:

Income Exclusions (Tips and Overtime): The excluded amounts from Part I of Schedule 1-A reduce your adjusted gross income (AGI) on Form 1040, Line 8 (Other Income adjustments). These function as above-the-line deductions, meaning they reduce AGI regardless of whether you itemize.
Below-the-Line Deductions (Car Loan Interest and Senior Enhancement): The amounts from Part II flow to Form 1040 as additional adjustments that reduce taxable income. The car loan interest deduction and the senior standard deduction enhancement are reported separately and do not require you to itemize.

The form is structured so that you complete only the parts relevant to your situation. Each part is independent.

Schedule 1-A: Line-by-Line Walkthrough

Header Section

Your name(s) as shown on Form 1040 — Enter exactly as it appears on your 1040
Your Social Security number — Primary taxpayer SSN
Tax year — Calendar year (2026 for the first year this form is available)

Part I: Income Exclusions

Part I covers the two major income exclusions introduced by the OBBB.

Section A: No Tax on Tips Exclusion

Line 1 — Total tip income reported on Form W-2 (Box 7) or Schedule C

Enter the total amount of tip income you received during the tax year. This includes:

Tips reported on your W-2 in Box 7 (Social Security tips) and Box 1 (included in wages)
Tips reported as self-employment income on Schedule C

For most employees, your W-2 will break out tip income separately. If you have multiple W-2s with tip income, add them together.

Line 2 — Qualifying tip income eligible for exclusion

Not all tip income qualifies. The exclusion applies to cash tips and charged tips received in occupations where tipping is customary (food service, hospitality, personal care, transportation). Tips earned in non-tipping occupations or tips that are actually service charges set by the employer may not qualify.

Enter the portion of Line 1 that meets the qualifying criteria. The IRS instructions will include a worksheet to determine the qualifying amount.

Line 3 — Tip exclusion limitation

The exclusion is capped at ~$25,000 per year for single filers and ~$50,000 for married-filing-jointly filers. Enter the applicable limitation.

Line 4 — Allowable tip exclusion (lesser of Line 2 or Line 3)

Enter the smaller of Line 2 or Line 3. This is the amount of tip income excluded from your federal income tax. Note that tips remain subject to Social Security and Medicare taxes (FICA) — only the income tax is eliminated.

Section B: No Tax on Overtime Exclusion

Line 5 — Total overtime compensation reported on Form W-2

Enter the total overtime pay you received. Your employer should report overtime compensation separately on your W-2, or you can calculate it from your pay stubs (hours worked over 40 per week multiplied by your overtime rate).

Line 6 — Qualifying overtime compensation

Enter the portion of Line 5 that qualifies. The exclusion covers overtime pay for hours worked beyond 40 in a workweek by non-exempt employees as defined under the Fair Labor Standards Act. Salaried exempt employees generally do not earn qualifying overtime. The exclusion does not apply to self-employment income.

Line 7 — Overtime exclusion limitation

The overtime exclusion is also subject to an annual cap of ~$25,000 for single filers and ~$50,000 for married-filing-jointly filers. Enter the applicable limitation.

Line 8 — Allowable overtime exclusion (lesser of Line 6 or Line 7)

Enter the smaller of Line 6 or Line 7. Like the tips exclusion, overtime remains subject to FICA taxes.

Section C: Total Part I Exclusions

Line 9 — Total income exclusions (Line 4 + Line 8)

Add your tip exclusion and overtime exclusion together. This total flows to Form 1040 as an adjustment to income, reducing your AGI.

Line 10 — Transfer Line 9 to Form 1040, Line 8, Column B

Write the amount from Line 9 on Form 1040, Line 8 in the designated column. The IRS will update Form 1040 instructions to include a reference to Schedule 1-A amounts in this section.

Part II: Additional Deductions

Part II covers deductions that reduce taxable income but do not require itemizing on Schedule A.

Section D: Car Loan Interest Deduction

Line 11 — Total interest paid on qualifying auto loans

Enter the total interest you paid during the tax year on loans used to purchase a qualifying vehicle. You should receive Form 1098 or a year-end statement from your lender showing the interest paid.

Line 12 — Vehicle qualification checklist (Yes/No)

Answer each of the following:

(a) Was the vehicle purchased new or used after the OBBB enactment date? Yes / No
(b) Is the vehicle registered in the taxpayer’s name? Yes / No
(c) Was the loan used exclusively to purchase the vehicle (not a cash-out refinance)? Yes / No
(d) Is the vehicle used primarily for personal transportation (not business)? Yes / No

You must answer Yes to all four to proceed. If any answer is No, enter $0 on Line 14 and skip to Section E. Business-use vehicles may qualify for other deductions on Schedule C instead.

Line 13 — Car loan interest deduction limitation

The deduction is capped at ~$10,000 per year for interest on auto loans for vehicles with a purchase price not exceeding ~$100,000. Enter the applicable limitation.

Line 14 — Allowable car loan interest deduction (lesser of Line 11 or Line 13)

Enter the smaller of Line 11 or Line 13. This deduction applies whether you take the standard deduction or itemize.

Section E: Senior Standard Deduction Enhancement

Line 15 — Age qualification

Check the box if you (or your spouse, if filing jointly) were age 65 or older by December 31 of the tax year.

Line 16 — Enhanced senior deduction amount

If you checked the box on Line 15, enter ~$6,000 per qualifying taxpayer. If both spouses on a joint return are 65 or older, enter ~$12,000.

This amount is in addition to the regular standard deduction and the existing additional standard deduction for taxpayers age 65 and over. It stacks on top of both.

Line 17 — Itemizer limitation

If you are itemizing deductions on Schedule A instead of taking the standard deduction, the senior enhancement may not apply. Check the box indicating your deduction method. If you are itemizing, enter $0 on Line 18.

Line 18 — Allowable senior deduction enhancement

Enter the amount from Line 16, unless you are itemizing (in which case enter $0).

Section F: Total Part II Deductions

Line 19 — Total additional deductions (Line 14 + Line 18)

Add the car loan interest deduction and the senior deduction enhancement. This total flows to Form 1040 as a further reduction to taxable income.

Line 20 — Transfer Line 19 to Form 1040, Line 12b

Write the amount on Form 1040 in the designated area. The IRS instructions will reference Schedule 1-A for this line.

Common Questions About Which Deductions Go Where

One of the most confusing aspects of Schedule 1-A is understanding how it interacts with other schedules you may already file.

Schedule 1-A vs. Schedule 1

Schedule 1 (Additional Income and Adjustments to Income) has existed for years and covers items like alimony, student loan interest, educator expenses, and self-employment tax deductions. Schedule 1-A is entirely new and separate. You may need to file both if you have, for example, student loan interest (Schedule 1) and qualifying tip income (Schedule 1-A).

Schedule 1-A vs. Schedule A

Schedule A covers itemized deductions like mortgage interest, state and local taxes (SALT), and charitable contributions. The car loan interest deduction on Schedule 1-A does not go on Schedule A. It is a standalone deduction that applies even if you take the standard deduction. Do not double-count car loan interest on both forms.

Schedule 1-A vs. Schedule C

If you are self-employed and receive tip income through your business, you still report that income on Schedule C for self-employment tax purposes. However, the income tax exclusion is claimed on Schedule 1-A. The tip income remains on Schedule C for calculating self-employment tax (Social Security and Medicare), but the exclusion on Schedule 1-A prevents it from being taxed as income tax.

Examples: Who Files Schedule 1-A?

Example 1: Restaurant Server

Maria works as a server and earned ~$38,000 in total wages, of which ~$22,000 was tip income reported on her W-2. She completes Section A of Part I, entering ~$22,000 on Line 2. Since the amount is below the ~$25,000 single-filer cap, she excludes the full ~$22,000 from income tax. Her AGI drops from ~$38,000 to ~$16,000, significantly reducing her tax bill. She still owes FICA on the full ~$38,000.

Example 2: Factory Worker with Overtime

James works in manufacturing and earned ~$55,000 in base pay plus ~$18,000 in overtime. He completes Section B of Part I, entering ~$18,000 on Line 6. This is below the ~$25,000 cap, so he excludes the full ~$18,000 from income tax. His income tax is calculated on ~$55,000 instead of ~$73,000.

Example 3: Retiree Age 68

Patricia is 68, retired, and takes the standard deduction. She completes Section E of Part II, entering ~$6,000 on Line 16. This adds to her existing standard deduction of ~$16,100 (single) plus the existing ~$1,950 additional amount for age 65+, giving her a total deduction of approximately ~$24,050.

Example 4: Multiple Provisions

David is a 66-year-old rideshare driver who also works part-time as a bartender. He has ~$8,000 in tip income, ~$5,000 in car loan interest, and qualifies for the senior enhancement. He completes Sections A, D, and E, claiming all three on a single Schedule 1-A.

Filing Tips and Common Mistakes

Do not forget FICA. The tips and overtime exclusions only eliminate income tax, not Social Security or Medicare tax. Your W-2 will still show these amounts for FICA purposes.
Keep documentation. For the car loan interest deduction, retain your loan statements showing interest paid. For tips, keep a daily tip log if your employer does not track tips accurately.
Check the caps. The exclusion caps for tips and overtime are per-person, not per-household. Each spouse on a joint return can claim up to the single-filer cap individually, effectively doubling the benefit.
Senior enhancement stacks. The ~$6,000 OBBB senior deduction is in addition to the existing additional standard deduction for age 65+. Do not confuse the two or assume one replaces the other.
E-file compatibility. Major tax software providers (TurboTax, H&R Block, FreeTaxUSA) are expected to support Schedule 1-A for the 2026 filing season. The software will generate the form automatically based on your answers during the interview process.

When Schedule 1-A Takes Effect

Schedule 1-A applies starting with the 2026 tax year (returns filed in early 2027). It does not apply retroactively to 2025 returns. If you are filing your 2025 return in April 2026, you will not use this form.

The IRS is expected to publish the final version of Schedule 1-A and its instructions by late 2026, ahead of the 2027 filing season. Draft versions may be available earlier for tax professional review.

Frequently Asked Questions

Can I claim both the tips exclusion and the overtime exclusion?

Yes. The exclusions are independent. If you earned both qualifying tips and qualifying overtime in the same tax year, you can claim both on a single Schedule 1-A. Each has its own cap.

Does the car loan interest deduction replace the mortgage interest deduction?

No. The car loan interest deduction is a new, separate provision. Mortgage interest is still deducted on Schedule A if you itemize. The car loan interest deduction applies even if you take the standard deduction.

I am 65 and I itemize. Can I still claim the senior enhancement?

No. The ~$6,000 senior standard deduction enhancement is only available to taxpayers who take the standard deduction. If you itemize on Schedule A, you cannot claim it. However, you should compare your total itemized deductions to the standard deduction plus the senior enhancement to see which method gives you a larger deduction.

My employer did not separate overtime on my W-2. What do I do?

You can use your pay stubs or payroll records to calculate overtime compensation. The IRS instructions for Schedule 1-A include a worksheet for computing overtime when it is not broken out on the W-2. Keep supporting documentation in case of an audit.

Is Schedule 1-A required even if I use tax software?

If you use tax software, the program will generate Schedule 1-A automatically when applicable. You will answer questions during the interview about tips, overtime, car loans, and your age, and the software will populate the form. If you file on paper, you must complete and attach Schedule 1-A yourself.

How does Schedule 1-A interact with state taxes?

Schedule 1-A is a federal form. States may or may not conform to the OBBB provisions. Some states will adopt the tips and overtime exclusions; others will not. Check your state’s conformity rules or consult a tax professional. For more on federal filing requirements, see the tax filing deadlines for 2026.
