The New IRS Schedule 1-A: Your Guide to the Four New Deductions for Tips, Overtime, Car Loans, and Seniors

You worked the extra shift, reported every cash tip, financed a new car for your commute, or celebrated a 65th birthday in your household last year. You did the work, earned the money, and paid the interest — and the tax return you file in early 2026 is the first one with a brand-new form built specifically to reward those four experiences.

That form is Schedule 1-A, Additional Deductions, and if you qualify for even one of the four new deductions it holds, you can claim the benefit whether you take the standard deduction or itemize. But the IRS gave taxpayers only a four-year window — 2025 through 2028 — and tied every dollar to modified adjusted gross income, occupation lists, VINs, and filing-status rules that will quietly disqualify an otherwise valid claim if you miss a checkbox.

This guide walks you through what Schedule 1-A is, who each deduction is actually for, how the phaseouts work, and the bookkeeping you need in place now so the number you write on the form is the number you can defend later.

What Is Schedule 1-A and Why Did the IRS Create It?​

Schedule 1-A was created for tax year 2025 by the One, Big, Beautiful Bill (P.L. 119-21, signed July 4, 2025) and published by the IRS on March 2, 2026 (IR-2026-28) with instructions folded into the Form 1040 packet. It exists for one reason: to consolidate four brand-new below-the-line deductions in a single place so taxpayers can calculate a total additional deduction and reduce taxable income on Form 1040, Form 1040-SR, or Form 1040-NR.

Before this law, none of these deductions existed. Now they do, but only for tax years 2025 through 2028 unless Congress extends them.

Three details catch people the first time:

It is not Schedule A. Schedule A is where you itemize mortgage interest, state and local taxes, and charitable gifts. Schedule 1-A is entirely different. You attach it in addition to your regular return, and you can use it even if you claim the standard deduction. The IRS is explicit that these new deductions are not reported on Schedule A.

It goes to Form 1040 as an additional deduction. The total from Schedule 1-A flows to your 1040 as a reduction of taxable income — not as a credit and not as an adjustment to AGI. That means it lowers federal income tax, but it does not reduce Social Security, Medicare, or most state and local taxes on the same dollars.

All four phase out with income. Each deduction has its own MAGI threshold, and the calculation for MAGI is done in Part I of Schedule 1-A itself: your AGI plus any excluded foreign earned income, foreign housing exclusion or deduction, and excluded income from bona fide residents of American Samoa and Puerto Rico. If you live and work entirely in the United States and do not exclude foreign income, MAGI equals AGI for this purpose — but the form still makes you work through Part I so the math is consistent.

The Four Deductions at a Glance​

Keep that table handy — the rest of the guide explains how to know which row is yours and what to save to prove it.

Deduction 1: No Tax on Tips — Up to $25,000​

Who qualifies​

You do not qualify simply because you received tips. Three filters apply:

1. Your occupation must be on the IRS list. The IRS maintains a published list at IRS.gov/TippedOccupations of occupations that customarily and regularly receive tips — servers, bartenders, barbers, taxi drivers, and similar tipped roles. If your job is not on that list, the tips are still taxable income, but they are not deductible on Schedule 1-A.

2. The tips must be reported. Qualified tips must appear on a Form W-2, Form 1099, another statement furnished to you, or on Form 4137 if you directly report tips that were not reported by an employer. Cash tips you never reported anywhere do not create a deduction; they create an exposure.

3. You must have a Social Security number valid for employment, and if married, you must file jointly. This rule applies to both the taxpayer and spouse if both claim the deduction. Married filing separately does not qualify.

Both employees and self-employed individuals can qualify if the occupation and reporting tests are met. The deduction covers tax years 2025–2028 and is capped at $25,000 per return, not per person.

How the phaseout works​

The deduction begins to shrink once MAGI exceeds $150,000 for single, head of household, and married filing separately filers ($300,000 for married filing jointly). Above that threshold the allowable deduction is reduced proportionally until it phases out completely. If you are near the boundary, accelerating or deferring income by even $1,000 can change the result by hundreds of dollars, which is why Part I of Schedule 1-A asks for MAGI before it lets you claim anything in Part II.

What still gets taxed​

No-tax-on-tips is a federal income tax deduction only. Tips remain subject to Social Security and Medicare taxes, and most states still tax them as ordinary income. Do not adjust your payroll withholding to zero on the assumption that tips are tax-free; the deduction is taken at filing time on Schedule 1-A.

Practical tip: Keep a daily tip log — date, amount, and whether cash, card, or pooled — and reconcile it monthly to your W-2 Box 7 and pay stubs. If you file Form 4137, keep the supporting log for at least three years; the IRS matches reported tips across information returns before allowing the deduction.

Deduction 2: No Tax on Overtime — Up to $12,500 ($25,000 Joint)​

It is not all overtime dollars — it is the premium half​

This is the single most misunderstood point. The OBBBA allows a deduction for qualified overtime compensation required under the Fair Labor Standards Act. In practice that means only the extra half-time premium — the half above your regular rate that makes time-and-a-half — not the full gross overtime payment.

Example: If your regular rate is $24 per hour and you work 10 overtime hours in a week, your employer pays you $360 for those hours ($36 × 10). Only $120 of that — the $12-per-hour premium — is potentially deductible as qualified overtime. If your employer pays overtime that is not FLSA-required (for example, daily overtime under a union contract or state law that exceeds the federal 40-hour weekly threshold), that amount does not qualify.

Who qualifies and what to save​

• The overtime must be reported on a Form W-2, Form 1099, or other statement furnished to you, or reported directly by you with supporting records. Employers are adapting payroll reporting for 2025 to isolate qualified overtime, often in Box 14 or a supplemental statement — keep that statement.
• The same SSN and joint-filing rules as the tips deduction apply.
• The cap is $12,500 per return for most filers and $25,000 for married filing jointly. The cap applies to the deductible premium amount, not to total overtime hours.
• The deduction is available 2025–2028 and phases out on the same MAGI thresholds as the tips deduction: $150,000 single / $300,000 joint.

Example​

A single ICU nurse with a $68,000 salary earns $9,000 in FLSA-qualified overtime premium during 2025 and has MAGI of $77,000. The full $9,000 is deductible on Schedule 1-A Part III. A colleague with the same overtime but MAGI of $152,000 sees the deduction begin to phase down, even though the hours are identical.

Practical tip: Save every pay stub that shows regular hours, overtime hours, and overtime rate separately, plus any employer year-end statement that breaks out qualified overtime. Timecards alone are not enough if the stub does not distinguish the premium.

Deduction 3: No Tax on Car Loan Interest — Up to $10,000​

What counts as qualified passenger vehicle loan interest (QPVLI)​

Part IV of Schedule 1-A uses a precise definition. All of these must be true:

• The vehicle is new and is a qualified passenger vehicle for personal use. Used vehicles do not qualify, and vehicles purchased for business-only use with 100% business deduction do not qualify here either. Personal use is required.
• You bought it, you did not lease it. Lease payments, even if they embed an interest component, are not deductible here.
• The loan was originated after December 31, 2024. A refinance of an older purchase or a loan that predates 2025 does not become qualified because you are paying interest in 2025.
• The proceeds were used to purchase the vehicle and the loan is secured by a first lien on that vehicle. Personal loans, credit-card purchases, or loans secured by other property do not qualify.
• You report the vehicle identification number (VIN) on Schedule 1-A. The IRS will match VINs to titling records. A missing or incorrect VIN can delay or deny the deduction.

You may deduct only interest paid during the tax year, up to $10,000. Principal is never deductible, and late fees are not interest.

The phaseout with a visible dollar example​

This deduction has the lowest entry point: MAGI over $100,000 for single filers ($200,000 for joint filers) begins the phaseout. The IRS reduces the allowable deduction by $200 for each $1,000 of MAGI above the threshold. At $150,000 single ($250,000 joint) the deduction is fully gone.

Worked example: You are single, paid $7,800 in qualified car-loan interest in 2025, and have MAGI of $120,000. You are $20,000 over the $100,000 threshold — 20 increments of $1,000 — so the reduction is 20 × $200 = $4,000. Your maximum before phaseout would have been $7,800 (capped at $10,000), and after phaseout it becomes $3,800. If you had paid only $3,900 in interest, the same $4,000 reduction would wipe the deduction to zero, which surprises borrowers who assume any interest under $10,000 is automatically deductible.

Married filing separately is not eligible at all for this deduction, regardless of income.

What to save​

Keep the loan origination disclosure showing the date, the purchase agreement showing the vehicle is new, the title or lien filing showing the first lien, and the lender's year-end interest statement. Many lenders did not issue a dedicated QPVLI statement for 2025; a Form 1098 or annual interest statement plus the origination packet is what examiners ask for.

Deduction 4: Enhanced Deduction for Seniors — $6,000 Per Person ($12,000 Joint)​

Who qualifies​

• You are age 65 or older on the last day of the tax year. For 2025, that means born before January 2, 1961.
• If married, both spouses can each claim $6,000 for a total of $12,000, but only if you file jointly.
• The deduction is a flat additional amount, not tied to actual expenses. You do not need to show medical bills or senior-care costs to claim it.

The phaseout​

Part V phases out on a lower threshold than the other three: MAGI over $75,000 for single filers and $150,000 for married filing jointly begins the reduction, calculated as 6% of the excess MAGI above the threshold. That makes this deduction sensitive for retirees whose MAGI includes Social Security, required minimum distributions, and investment income together.

Example: A single filer age 67 with MAGI of $85,000 is $10,000 over the $75,000 threshold. The reduction is 6% × $10,000 = $600, so the $6,000 deduction becomes $5,400. A married couple both 68 with MAGI of $170,000 is $20,000 over the $150,000 joint threshold; reduction is $1,200, so their $12,000 becomes $10,800.

Like the other three, you claim this whether you itemize or take the standard deduction, and you claim it on Schedule 1-A Part V, not on the old line for the additional standard deduction for age 65+ — that separate amount continues to exist and can stack.

Part I: How MAGI Controls All Four​

Do not skip Part I. The IRS orders Schedule 1-A so Part I must be completed first because every deduction in Parts II–V references the number you calculate there.

For most individual filers, Schedule 1-A MAGI is simply AGI from Form 1040 line 11. You add back only if you excluded foreign earned income, foreign housing amounts, or income from American Samoa or Puerto Rico. If none of those apply, your MAGI for Schedule 1-A is your AGI — but you still enter it in Part I so the phaseout worksheets can point to it.

Why this matters for planning: MAGI for Schedule 1-A is not the same as MAGI for other phaseouts like Roth IRA or premium tax credits, which add back different items. Use the Schedule 1-A worksheet, not a remembered number from another form. Near a threshold, actions that lower AGI — a larger pre-tax 401(k) contribution, an HSA contribution, or timing a Roth conversion into the following year — can preserve a deduction worth up to $25,000 of taxable income. The time to model that is November, not April.

How to Complete Schedule 1-A Step by Step​

1. Complete Form 1040 through AGI. You need line 11 before you can start Schedule 1-A.
2. Fill Part I (MAGI). Transfer AGI and add back any applicable foreign exclusions.
3. Work Parts II–V only if you qualify. Leave a part blank if you do not have that type of income or interest. Do not enter zero in a part that does not apply — blank is the IRS signal that you are not claiming it.
4. Apply the caps and phaseouts inside each part. Each part has its own worksheet. The forms are designed so the phaseout math happens inside the part; you carry only the allowed amount forward.
5. Sum the allowed amounts and transfer the total to Form 1040. For 2025 the total additional deduction from Schedule 1-A is reported as an adjustment to taxable income on Form 1040. Keep the schedule attached; it is the support for the number on the front page.

Before you file, run this checklist:

• Every dollar of tips or overtime you deduct appears on an information return or Form 4137 and matches your tip log or pay stubs.
• Your occupation is on the IRS tipped-occupations list if you claimed the tips deduction.
• You have the supplemental employer statement that isolates qualified overtime premium, not just gross overtime.
• Your car-loan packet shows a post-2024 origination date, first lien, personal-use purchase of a new vehicle, and you entered the correct 17-character VIN.
• If married, you filed jointly for any part you claimed.
• You entered an SSN valid for employment for each person claiming tips or overtime.

Common Mistakes That Cost the Deduction​

Mixing up gross overtime with the deductible premium. Entering the full $360 from the earlier example instead of the $120 premium is the most common error on early 2025 drafts. Software will not catch it if you give it the wrong starting number.

Assuming a used car qualifies. The statute says new. A one-year-old demonstrator or a certified pre-owned vehicle purchased in 2025 does not meet the definition even if the loan is new.

Forgetting that married filing separately kills two of the four. For car-loan interest, married filing separately is ineligible outright. For tips, overtime, and seniors, filing separately caps you at the lower threshold and, for tips and seniors, can eliminate the claim entirely if you would otherwise have qualified jointly.

Leaving the VIN blank or transposed. A single-character VIN error can trigger a notice and a full disallowance of Part IV until corrected.

Claiming the deduction without the SSN rule satisfied. An ITIN-only filer who received qualified tips may report the tips correctly and still be ineligible for the deduction. The SSN must be valid for employment.

Thinking the deductions are permanent. They expire after 2028. If you are planning a vehicle purchase or budgeting tip income, do not assume the same form will exist for 2029.

Keep Your Records Ready So the Deduction Sticks​

Each of these deductions turns on paper you already handle in your business or household, but the IRS now asks for it in a more connected way:

• Tipped workers and employers: Daily tip reports, point-of-sale tip summaries, and W-2 Box 7 reconciliations. Employers should keep the tipped-occupation determination and employee tip agreements on file.
• Hourly workers and payroll administrators: Time-and-attendance records that show regular versus overtime hours, FLSA workweek definitions, and payroll registers that break out the half-time premium. If you are self-employed and hire hourly help, keep the same records for your own qualified overtime.
• Vehicle buyers: The closed loan disclosure, purchase agreement, title/lien filing, VIN, and the lender's annual interest statement. Track interest versus principal in your bookkeeping so the Schedule 1-A number ties to an amortization schedule, not a guess.
• Seniors: A copy of the birth-date evidence and the joint return itself. If MAGI is near $75,000/$150,000, retain the worksheets that show the 6% reduction — you will be asked for them.

Good bookkeeping is not just about closing the books each month; it is the difference between confidently claiming $10,000 on Part IV and leaving it on the table because you cannot find the lien date or the VIN by April 10. A simple year-end folder — pay stubs, W-2s, 1099s, tip logs, overtime statements, loan packet, lender interest statement, and birth-date verification — covers all four deductions.
