W-2 Extractor Publishes a Free Box 12 Decoder Covering the Three Codes New for 2026

Codes TA, TP and TT appear on the Form W-2 furnished in January 2027 and are the substantiation for two new Schedule 1-A deductions.

FOLSOM, Calif., August 21, 2026 — W-2 Extractor has published a free decoder for all 33 Form W-2 Box 12 codes, including the three added for tax year 2026 (TA, TP and TT), two of which are already inside Box 1 taxable wages and identify a deductible slice rather than extra income.

TA, TP, TT (33 codes total): Tax year 2026 adds three Box 12 codes to Form W-2.; Source: 2026 General Instructions for Forms W-2 and W-3
included in Box 1: Code TP reports total cash tips reported to the employer and is the substantiation for the Schedule 1-A tips deduction. It is already included in Box 1.; Source: 2026 General Instructions for Forms W-2 and W-3
premium half only: Code TT reports total qualified overtime compensation: the FLSA-required premium only, not the full overtime paycheck. It is also already inside Box 1.; Source: 2026 General Instructions for Forms W-2 and W-3; IRC §225
excluded from Box 1: Code TA reports employer contributions to a Trump account and is EXCLUDED from Box 1, so it is not deducted a second time.; Source: IRC §128; 2026 General Instructions for Forms W-2 and W-3
up to 2 codes; 71 eligible occupations: A new Box 14b carries the Treasury Tipped Occupation Code. A tipped worker whose Box 14b is blank has no substantiation for the tips deduction.; Source: 2026 General Instructions for Forms W-2 and W-3; Treasury Tipped Occupation Codes, final regulations

Box 12 of Form W-2 is a lettered code list, and the codes are not self-explanatory on the form itself. For tax year 2026 the list grows by three entries that exist because of the One Big Beautiful Bill Act, and two of them are easy to double-count.

TP (total cash tips reported to the employer) and TT (total qualified overtime compensation) are informational splits of wages that are already inside Box 1. They exist so a taxpayer can compute the Schedule 1-A tips and overtime deductions, which subtract the deductible portion. Treating either as income to add on top of Box 1 overstates wages; treating either as a deduction already taken understates the Schedule 1-A entry.

TA is the opposite case. Section 128 employer contributions to a Trump account for an eligible dependent were never taxed and are excluded from Box 1, so there is nothing further to deduct.

The decoder at w2extractor.com lists every Box 12 code with what it means, whether it is already inside Box 1, and what, if anything, the taxpayer does with it. It is free, requires no account, and is labelled an estimate and reference rather than tax advice.

“Two of the three new codes describe money that is already in Box 1. The failure mode is not missing the deduction, it is counting the same dollars twice in opposite directions.”
