No Tax on Overtime for Home Care Agencies: W-2 Box 12 Code TT for 2026
From 2026 W-2s, agencies must report each caregiver's qualified overtime (the half-time premium only) in box 12, code TT. How to calculate it and what to check before January.
By Caregiver Scheduling Team ·
Short answer. For tax year 2026, every home care agency must report each caregiver’s qualified overtime compensation on Form W-2, box 12, code TT. Qualified overtime is only the half-time premium the FLSA requires, not the full overtime check. Caregivers can deduct only what you report, so a wrong or missing box 12 costs them money.
General information, not tax advice. Rules change and depend on your facts. Confirm with the official source linked in each section or a CPA or enrolled agent before acting.
What changed for 2026?
The 2025 tax law (the IRS now calls it the Working Families Tax Cuts) created a deduction for qualified overtime for tax years 2025 through 2028. For 2025, employers had transition relief. For 2026, the IRS requires separate reporting on the W-2 in box 12 with code TT (FS-2026-13, updated August 6, 2026 per IR-2026-88).
Nothing changes in withholding. Overtime stays subject to federal income tax withholding, Social Security, Medicare and FUTA (FS-2026-13).
How do you calculate qualified overtime?
The IRS formula works week by week (FS-2026-13):
FLSA hours over 40 in the workweek × 0.5 × the caregiver’s FLSA regular rate
| Example week | Amount |
|---|---|
| Hours worked across all clients | 50 |
| Regular rate (including shift differentials that count toward the regular rate) | $18.00 |
| Overtime paid (10 × $27.00) | $270.00 |
| Qualified overtime for box 12 (10 × 0.5 × $18.00) | $90.00 |
Add the weekly amounts for the year. That total goes in box 12, code TT.
What doesn’t count?
- Overtime the FLSA doesn’t require. If you pay daily overtime under state law, or double time, only the amount needed to satisfy federal overtime counts (FS-2026-13). California daily overtime after 8 hours, for example, is not qualified unless the hours are also over 40 in the week.
- Exempt employees. Office staff paid on a salary under an FLSA exemption don’t generate qualified overtime, even if you pay them extra.
- Premium pay that isn’t overtime, such as holiday pay or a weekend differential, unless it is part of the regular rate calculation.
Does the companionship exemption matter here?
Yes. Today, federal rules bar home care agencies from claiming the companionship and live-in exemptions, so caregiver overtime over 40 hours is FLSA-required (DOL Home Care). DOL has proposed restoring those exemptions for agencies, and since July 2025 it has not been enforcing the bar (Field Assistance Bulletin 2025-4), but the rule itself is still in effect. If a final rule takes effect and an agency stops paying overtime under it, those hours would no longer produce qualified overtime. Overtime still owed under state law would not be qualified either. Track the status on the rule tracker.
Checklist before January 2027
- Ask your payroll provider whether its 2026 W-2 fills box 12, code TT from the premium only, not total overtime pay.
- Confirm overtime is calculated per workweek across all clients, including travel time between clients.
- Confirm the regular rate includes nondiscretionary bonuses and differentials.
- Separate state-only overtime (daily, seventh-day) from FLSA overtime in your pay codes.
- Spot-check five caregivers’ year-to-date figures against their timesheets in December.
- Tell caregivers where to find the number (see our caregiver explainer).
What if a W-2 is wrong?
If you under-report box 12, the caregiver generally needs a corrected W-2 (Form W-2c) to claim the full deduction (FS-2026-13). Fixing it early is cheaper than fielding calls in April.
How Caregiver Scheduling helps
Every visit, across all of a caregiver’s clients, has GPS-verified check-in and check-out times, which is the raw record behind any overtime figure. Timesheets that calculate weekly overtime with overnight shifts split at the week boundary, and a QuickBooks export that carries those hours to payroll, are coming soon. Your payroll provider produces box 12 and files the W-2.
FAQ
Do we stop withholding tax on overtime? No. Withholding is unchanged.
Is the deduction capped? Yes, for the caregiver: $12,500 per return, $25,000 for joint filers, with an income phase-out (IRS). Report the full qualified amount anyway.
Does this apply to 1099 contractors? Rarely, and caregivers who are controlled like employees should be W-2 employees anyway. See W-2 vs. 1099 caregivers.
When are W-2s due? January 31 (February 1, 2027, because January 31 falls on a Sunday). Confirm on the IRS W-2 instructions.
