Track the overtime you can deduct
For tax years 2025 through 2028, the extra half in time-and-a-half pay is deductible on your federal return, up to $12,500 a year ($25,000 on a joint return). Halfback finds it on the pay stubs you enter and keeps a running total for the year.
iPhone app. Free for one employer, with no time limit. No account and no ads.
What Halfback does
- Add a pay stub in seconds. Enter the pay date, your regular rate, overtime hours and overtime pay. Only the extra half counts, so Halfback shows the qualified part of each pay stub. If the overtime pay doesn't match time and a half, it asks you why instead of guessing.
- Your year at a glance. Qualified overtime for each pay stub and each tax year. A reminder on payday evening to add the pay stub while it's in front of you, and one in January when W-2s arrive. A Home Screen widget with your year's total and your next payday.
- Check your W-2. From 2026, employers report qualified overtime in box 12 of Form W-2, code TT. Halfback compares it with your pay stubs and shows the difference. If they differ, it prepares a request for a corrected W-2 (Form W-2c) for you to send to your employer.
- No account and no ads. Your pay data stays on your iPhone.

Halfback is an iPhone app for hourly employees in the United States. You enter your pay stubs, and it estimates your qualified overtime and your deduction for qualified overtime compensation (the "No Tax on Overtime" deduction) for tax years 2025 through 2028.

Is this tax advice?
No. Halfback's figures are estimates based on what you enter. Your Form W-2, your employer's payroll records and your tax return determine what you can deduct. Check important figures with a tax professional or the IRS before you file. Halfback is not affiliated with the IRS or any government agency.
Why is my estimate different from my W-2?
Halfback estimates from the pay stubs you enter. Check that every pay stub of the year is in, and that the overtime hours and overtime pay match your pay stubs. From 2026, your employer reports qualified overtime in box 12 of your W-2, code TT. With Pro, the W-2 check compares it with your pay stubs and can prepare a W-2c request for your employer.
