For 2026, employers report the overtime premium required by the Fair Labor Standards Act (FLSA) in W-2 Box 12, code TT, and cash tips in code TP. Penalty relief covered 2025 only. Check your payroll setup before January.
TL;DR: For 2026, employers report the overtime premium required by federal wage law in W-2 Box 12, code TT, and cash tips in code TP. If payroll runs in Dynamics GP, Microsoft’s own guidance says you need a process that tracks only the premium portion. Test one on a copy of live data this quarter. Then ask your CPA or payroll provider to confirm the result before January.
Your 2026 W-2 qualified overtime reporting has to be right the first time, and the payroll year is already winding down. So, the practical question. Which slice of an overtime check goes in Box 12?
Not the whole check. Only the premium, the extra half in time-and-a-half.
Sounds simple. Then you open the pay code list. Daily overtime, double time, holiday premiums, and shift differentials all stack on the base rate in different ways, and a payroll setup built years ago to pay people, not to feed a tax form, may not separate the premium at all. The 2025 penalty relief doesn’t carry over, and the IRS draft instructions list February 1, 2027 as the date for both the SSA copy and the employee statements. Waiting on a software update to sort it out is a gamble worth avoiding.
None of this is tax advice. Your CPA or payroll provider makes the final call.
What changed on the 2026 W-2?
The 2026 W-2 adds Box 12 code TT for qualified overtime, code TP for cash tips, and code TA for employer contributions to Trump accounts. Box 14 also splits into 14a and 14b. Easy to miss.
Box 14b holds the Treasury Tipped Occupation Code, and the old Box 14 entries move to 14a. Those details come from the IRS 2026 W-2 and W-3 instructions, which carry a January 29, 2026 date and a draft stamp. Experian says the final version followed on January 30.
| Item | 2026 W-2 treatment |
|---|---|
| Qualified overtime | Box 12, code TT |
| Cash tips reported to the employer | Box 12, code TP |
| Employer contributions to Trump accounts | Box 12, code TA |
| Treasury Tipped Occupation Codes | Box 14b |
| Copy A filing and employee statements | February 1, 2027 |
Overtime stays subject to income tax withholding and to Social Security and Medicare taxes. Box 12 is a reporting change. Withholding doesn’t move. Report the full qualified amount even when an employee can’t deduct all of it, according to the Journal of Accountancy’s August 2026 summary of the updated IRS FAQs. The provision sunsets December 31, 2028 unless Congress extends it, per BBK Law.
What counts as qualified overtime?
Only the premium that the FLSA requires counts. For time-and-a-half, that’s the extra half, not the full overtime pay. Anything paid above the FLSA amount stays out of Box 12.
BBK calls it the premium portion of FLSA-required overtime, not total overtime earnings. Overtime paid above the federal requirement, whether it comes from state law, a union agreement, or company policy, is nonqualified, and Bonadio makes the same point about double-time policies, which pay more than the FLSA asks for.
Round numbers, our own arithmetic, not a payroll rule. Say someone earns $20 an hour and works 45 hours in a week, so 5 hours are overtime.
| Pay rule on the 5 overtime hours | Overtime pay | Premium over the $20 rate | Reportable in code TT |
|---|---|---|---|
| Time-and-a-half ($30 an hour) | $150 | $50 | $50 |
| Double time ($40 an hour) | $200 | $100 | $50 |
Double time is the trap. You paid $100 of premium, but the FLSA only required $50. The other $50 stays out. The regular rate can also include more than base pay, so ask your payroll provider how yours is figured.
Daily overtime is another animal. BBK notes some employers pay overtime after 8 hours in a day, which doesn’t follow the federal formula. Whether those hours count? A CPA question.
Does the 2025 penalty relief still apply?
It doesn’t. Notice 2025-62 waived penalties for leaving the new tip and overtime information off 2025 forms, and BDO’s summary describes the relief as covering the 2025 tax year only. For 2026, BBK puts the standard penalty for an incorrect return at $680, with a second $680 possible for the employee’s copy, and says intentional disregard costs the greater of $680 per return or 10% of the qualified overtime that should have been reported, with no annual cap, so this isn’t a line item to leave to chance. Ask your CPA what applies to you.
How does Dynamics GP payroll handle the overtime premium?
Microsoft’s Dynamics GP post on the overtime premium is the best starting point. It says reporting was optional for 2025 and becomes mandatory for 2026, then describes two ways to isolate the premium. One is a SmartList view that filters by overtime pay code. The other is a non-taxable benefit built on those pay codes.
What it doesn’t settle is the year-end update. The Microsoft Learn year-end page, last updated December 5, 2025, covers the 2025 update and says there were no updates related to the W-2 overtime premium, which leaves the 2026 handling an open question. We found no 2026 write-up as of October 28, 2026.
One more wrinkle. The same post says Greenshades filers should enter TT in the Other line of Box 14, not Box 12, while the IRS draft puts TT in Box 12. Settle that with whoever files your W-2s. Early.
Argus is a Dynamics GP partner, so we’d be glad to help, but this isn’t a reason to change platforms, because the same pay code tangle follows you into any other system. If an outside provider runs your payroll, this section matters less, since the provider owns the mapping. And if nobody on staff knows how your overtime pay codes are built, a GP support partner can map them.
Where does the 33.33% shortcut break?
Microsoft’s post suggests a non-taxable benefit at 33.33% of the overtime pay codes, which it says should calculate just the premium. That works for a flat 1.5 times the rate, where the 0.5 premium is a third of the pay.
Double time breaks it. The FLSA premium on pay of two times the rate is 0.5, or 25% of the pay, so a 33.33% benefit on a $200 double-time code reports about $66.67 against the $50 above. A daily overtime code that isn’t FLSA overtime at all gets reported anyway. One percentage can’t fit every pay rule. Not even close. Test the benefit method and each percentage on a copy of your company data before relying on it.
What about tips?
If you have tipped employees, the IRS draft calls for code TP for cash tips reported to the employer and the Treasury Tipped Occupation Code in Box 14b. Microsoft’s overtime post gives no GP setup for tips. Same gap. No tipped staff? Skip this one.
What belongs on a pre-W-2 checklist?
Before the last 2026 payroll posts, list every overtime pay code, sort which are FLSA-required with your CPA, test the premium on a copy of live data, and settle where TT prints with your filer.
- Pull every pay code that pays more than straight time. Weekly overtime, daily overtime, double time, holiday pay, and any differentials riding on top.
- Sort them. Which are required by the FLSA, and which come from state law, a union contract, or company policy? Your CPA decides that.
- Copy the company. Run one pay period through the new setup and compare the premium to a hand calculation for three employees.
- Where does TT print? Ask your W-2 vendor. Today.
- Check your GP build, because each year-end update has a minimum release (the 2025 one required 18.8 or higher). Your version history is the place to start.
- One name on the task.
- Put February 1, 2027 on the calendar and work backward.
Pay codes that have grown by accretion over the years are a good example of why optimizing the setup you already have comes before any talk of a new system. Year-end isn’t the only payroll deadline on the horizon, either. See what happens to payroll tax updates after Dynamics GP end of life.
What if a W-2 is wrong?
File a W-2c and give the employee the corrected form, per the IRS overtime FAQs as summarized by the Journal of Accountancy. Employees can’t use Form 4852 to claim overtime that never made it onto a W-2, so an understated Box 12 sends them straight back to you. Fixable, but it’s extra work in January.

Questions That Come Up Before W-2 Season
Do tips and overtime change what we withhold?
Not automatically. Overtime stays subject to income tax withholding and to Social Security and Medicare taxes, and employers don’t reduce withholding on their own. An employee who wants less withheld submits a new W-4. Microsoft’s post says GP doesn’t support new W-4 field 4(b) and suggests a negative additional withholding amount as a workaround. Test that first.
Does a salaried employee’s overtime count?
Think FLSA first, tax second. Only FLSA-required overtime counts, so an employee who is exempt from FLSA overtime has no qualified overtime to report. The IRS FAQs, as summarized by the Journal of Accountancy, note that an employee who owns at least a bona fide 20% equity interest and actively manages the business is generally exempt and therefore ineligible. Exempt status is a legal call, so ask your CPA or employment counsel.
When is the W-2 due?
February 1, 2027. The IRS draft instructions list that date for both Copy A to the SSA and the employee statements, and extensions aren’t automatic.
Why does Microsoft’s post mention Box 14TT?
The post refers to a Greenshades filing quirk, and the IRS draft instructions put code TT in Box 12 instead. If a vendor maps it differently, ask them why, and get the answer in writing before the file goes out. When sources disagree, the final IRS instructions win.
Does this rule expire?
Eventually. BBK Law says the provision sunsets December 31, 2028 unless Congress extends it.
