Two lines on a tax return decide whether a waiter, a nurse working extra shifts or a delivery driver keeps a new deduction. One is a Social Security number. The other is a filing status, and for married workers only one choice works.
The Internal Revenue Service (IRS) attaches both conditions to the “no tax on tips” and “no tax on overtime” deductions created by the 2025 budget law. A worker who leaves the number off, or a married couple that files separately, can lose a deduction worth up to $25,000 on tips or $12,500 on overtime.
For anyone with tip or overtime pay on a 2025 W-2, the question is what the return has to show, and what a married worker has to do, before the deduction counts.

The Social Security number on the return
The IRS says taxpayers must “include their Social Security Number on the return” to claim either deduction. The IRS fact sheet is the free official route for the rules, and it applies the requirement to tips and overtime alike. The agency published it as FS-2025-03 in July 2025.
A later IRS explainer on the new Schedule 1-A, issued as FS-2026-04 in March 2026, adds detail. It says the taxpayer or spouse who received the tips “must have a Social Security number valid for employment to claim the deduction.” The overtime language is the same. In plain terms, a number that does not authorize work does not qualify.
Married workers and the joint return
The fact sheet’s wording on filing status is short: taxpayers must “file jointly if married, to claim the deduction.” The Schedule 1-A explainer repeats it for each deduction: “If married, they must file jointly to claim this deduction.”
Neither IRS page offers a separate-return route for a married tipped or overtime worker. Single filers and heads of household are not asked to change anything. The condition applies only to married filers, and for them the joint return is the only way to the deduction.
What the two deductions cover
Both deductions are effective for 2025 through 2028. The tips deduction has a maximum of $25,000 a year. The overtime deduction tops out at $12,500, or $25,000 for joint filers. The IRS says each one phases out for taxpayers with modified adjusted gross income, which is income after certain adjustments, above $150,000, or $300,000 for joint filers.
Pay has to be reported on a Form W-2, a Form 1099 or another specified statement given to the worker. Self-employed filers may also report tips on Form 4137. Self-employed people in a specified service trade or business under section 199A are not eligible for the tips deduction.
Which jobs count as tipped work
Only tips earned in an occupation that “customarily and regularly” received tips on or before December 31, 2024, count. The IRS keeps a list of occupations that received tips on its site, last updated June 28, 2026. It names 71 occupations in 8 categories, from beverage and food service to transportation and delivery.
Bartenders and wait staff are on it, and so are musicians and singers and tutors. A worker whose job is not on the list cannot claim the tips deduction, even if customers leave money. Overtime is judged differently: the IRS ties it to qualified overtime pay reported on the worker’s pay statements.
Where the deductions go on the return
The IRS overview of Schedule 1-A, the new form for these extra deductions, shows tips in Part II and overtime in Part III. Part VI totals the deductions, and that total goes on line 13b of Form 1040. The schedule is used with a 2025 tax return.
The same schedule carries the enhanced deduction for seniors, $6,000 per person aged 65 or older. Older workers who earn tips or overtime may therefore have several lines on one form, each with its own Social Security number and joint-filing condition. The IRS says all four deductions on the form are subject to income phaseouts.
That matters for retirees who kept working part-time. A 66-year-old server married to a retired spouse, for instance, faces the joint-filing rule for the tips deduction and the senior deduction at once.
Will a missing number or a separate return cost an older worker’s deductions?
A worker over 65 who earns tips or overtime and files without a valid-for-employment Social Security number, or files separately while married, can lose the tips or overtime deduction. The senior deduction is also tied to joint filing, so one wrong filing status can remove several deductions in a single move.
