2026 W-2 Codes TP, TT and TA: A Quick Guide for Tax Pros

When clients bring in their 2026 W-2s during the 2027 filing season, your team will see some new codes. And this is one update worth training on before January, because code TP does not automatically mean deductible tips.

Here’s the quick breakdown.

What the new codes mean

Start with the code itself, then ask whether the payment meets the eligibility rules.

Put another way, the W-2 is giving you two related but separate pieces of information. Code TP reports a total; the occupation code helps you decide whether the employee’s work falls into the qualified category. A preparer who enters TP as the deduction without reviewing 14b could overstate the amount even when every number on the W-2 was typed correctly.

An employee who worked as a server and also in a nonqualifying position may have tips from both roles. The W-2 may show the combined tips plus occupation codes, but the preparer still needs the split if only part qualifies. That’s a follow-up for the employer or client records—not a reason to guess at an allocation.

Why Box 14b matters so much

If Box 12 shows $18,000 under code TP, don’t immediately enter $18,000 as qualified tips. Verify the occupation and the remaining eligibility requirements.

A code of 000 identifies nonqualifying tipped work. If a W-2 includes both 000 and a qualifying occupation code, you’ll need to determine how much of the tips came from each role. A single TP total may not give you that answer.

This is one of those details that looks minor on the form and can create a major issue on the return.

Try a quick training example. Employer A reports $16,400 in code TP for a qualifying tipped occupation. Employer B reports $5,200 in code TP but lists only occupation code 000. You don’t automatically combine the amounts into $21,600 of qualified tips. Start with the qualifying amount and then apply the applicable limits and income phase-out. Using both reported totals could overstate the deduction by $5,200 before any calculation begins.

The same careful reading applies to code TA. It identifies certain employer contributions under the Trump account program; it isn’t an amount the employee paid and can simply deduct on Form 1040.

Don’t double-count the overtime amount

Code TT already reports the qualified premium. If the amount is $3,000, you generally start with $3,000—not one-third of it again.

If the amount is missing or appears too low, ask for payroll records and determine whether the employer needs to issue Form W-2c. Under the IRS’s post-2025 guidance, Form 4852 cannot be used to substitute a higher qualified-overtime amount.

One more detail that matters when comparing years: employers had transitional relief in reporting tips and overtime for 2025. The 2026 W-2 has its own designated boxes and codes. Don’t take a 2025 workpaper method and paste it into a 2026 return just because the new form looks unfamiliar.

If code TT appears unusually small, compare it with the pay records, taking into account the fact that only the qualifying premium counts. A $3,000 TT amount can be consistent with $9,000 of ordinary time-and-a-half overtime compensation. First check the math; request a W-2c only when the underlying reported amount really is wrong.

Make this a review checkpoint

Before your team e-files a return with a new deduction, ask:

• Did we read Box 14b before treating code TP as qualified tips?
• Did we use code TT only once and apply the correct limits?
• Did we check filing status, valid SSNs and income phase-outs?
• Is a corrected W-2 needed before the return can be completed?

Before filing season opens, show your preparers an example W-2 with TP, TT, TA, 14a and 14b circled. Ask them to explain what each code means and which amounts still require an eligibility decision. Then test the software’s Schedule 1-A output. A five-minute training exercise now can prevent the same error from being repeated all season.

The takeaway: Teach the new W-2 codes, then make them a consistent review checkpoint. Our Forms and Schedules Cheat Sheet 2026 puts reporting connections and common errors in one quick reference; the 1040 Practice Returns pack offers broader W-2 and individual-return practice scenarios.
