Starting with 2026 wages, employers must report each employee's qualified overtime premium on Form W-2. Payroll tools often miss bonuses, multiple pay rates and early-year paychecks. TT Check recalculates it week by week from the FLSA regular rate.
Nondiscretionary bonuses raise the regular rate. The "overtime pay ÷ 3" shortcut ignores them and understates code TT.
Prevailing wage, different job rates or shift rates require a weighted-average regular rate. Many setups can't calculate it automatically.
If tracking started late or was set up wrong, year-to-date totals are off and need a per-paycheck correction before W-2s go out.

Per week: regular rate = (Σ rate × hours + nondiscretionary bonus) ÷ total hours; qualified OT = 0.5 × regular rate × hours over 40. Each workweek stands alone. Amounts rounded to cents per week.

Buy 1 client Buy 10-packTODO: replace with Stripe Payment Links ($99 and $499)Starting in tax year 2026, employers must report qualified overtime compensation on Form W-2, box 12, code TT (IRS FS-2026-13, Q10). It's the premium portion of FLSA-required overtime, not total overtime pay.
Each workweek: FLSA hours over 40 × one-half × the employee's FLSA regular rate (IRS FS-2026-13, Q12). The regular rate is total includable pay for the week divided by total hours worked (Q15; DOL Fact Sheet #56A).
Nondiscretionary bonuses (attendance, production, safety, promised bonuses) are included in the regular rate. Truly discretionary bonuses, gifts and other statutory exclusions are not (DOL Fact Sheet #56A). Enter only includable amounts.
Only FLSA overtime (over 40 hours in a workweek) counts toward code TT. This calculator uses the weekly 40-hour rule only, so daily or contractual overtime doesn't add to the result.
The IRS says errors in code TT must be corrected with Form W-2c (FS-2026-13, Q11). Fixing it before W-2s go out is far easier.

Not tax or legal advice. TT Check is a calculation tool for educational and informational purposes. Results depend on the data you enter and on simplifying assumptions (weighted-average regular rate, bonuses allocated to the week they were earned, 40-hour weekly FLSA overtime only). Confirm amounts with your payroll provider or a qualified tax professional before filing.
