Form W-2 for 2026: Box-by-Box Guide, Box 12 Codes and What Changed

Your 2026 Form W-2 is due from your employer by February 1, 2027. New for 2026: box 12 codes TP (cash tips reported) and TT (qualified overtime), which feed the new tips and overtime deductions, code TA (Trump account contributions), and box 14b for the tipped-occupation code (IRS W-2 instructions (2026)). Box 1 is your taxable wages for income tax; boxes 3 and 5 are your Social Security and Medicare wages, which still include 401(k) deferrals.

Box 1 vs box 3 vs box 5: a worked example

A single employee earns $70,000 in 2026, defers $6,000 to a traditional 401(k) and pays $5,000 of health premiums and HSA contributions through the employer’s cafeteria plan. The 401(k) money leaves box 1 but stays in boxes 3 and 5; the cafeteria-plan money leaves all three, which is why it also saves Social Security and Medicare tax ($4,973 instead of $5,355 on $70,000) (W-2 instructions, box 3; Publication 15).

Computed by the federal engine (boxes 4 and 6: its payroll rule; tax: the 2026 return, standard deduction).

Common questions

When will I get my 2026 W-2?
Employers must furnish 2026 Forms W-2 to employees by February 1, 2027, the same date they file them with the Social Security Administration (IRS W-2 instructions (2026)). If yours has not arrived, ask the employer for it; if a box is wrong, ask for a corrected Form W-2c.
What is a statutory employee?
A worker who is an independent contractor under the common-law rules but is treated as an employee by statute for Social Security and Medicare tax: certain commission drivers, full-time life insurance sales agents, home workers and full-time traveling or city salespeople. Their employer checks box 13 “Statutory employee”, withholds Social Security and Medicare tax but not income tax, and they report the income and expenses on Schedule C (IRS: Statutory employees).
What is the difference between a W-2 and a 1099-NEC?
A W-2 reports an employee’s wages, with income tax and FICA withheld. A 1099-NEC reports nonemployee compensation paid to an independent contractor, with nothing withheld: the contractor pays income tax and 15.3% self-employment tax, usually through quarterly estimated payments (IRS: Form 1099-NEC).
Why is box 1 lower than boxes 3 and 5?
Box 1 leaves out pre-tax 401(k), 403(b) and 457(b) deferrals; boxes 3 and 5 include them, because those deferrals are still subject to Social Security and Medicare tax. Cafeteria-plan (section 125) health premiums, health FSA and HSA payroll contributions come out of all three (W-2 instructions). In the example, box 1 is $59,000 and boxes 3 and 5 are $65,000.
What changed on the 2026 W-2?
New box 12 codes TP (cash tips reported to the employer), TT (qualified overtime compensation) and TA (employer contributions to a Trump account), and box 14 split into 14a (other) and 14b (Treasury tipped occupation code), so workers can claim the new tips and overtime deductions (IRS W-2 instructions (2026)).
