W-2 Box 14 Explained for 2026: What the Other Box Actually Reports

Overview

What Is Box 14 on Form W-2?

Box 14 is the free form section of Form W-2. Unlike Box 12, which uses a fixed set of IRS letter codes, Box 14 has no required list. The employer decides what goes in, writes a short label, and enters an amount. The IRS asks employers to label each item so the employee (and any tax preparer) can identify it. Typical entries include state disability insurance withheld, union dues, uniform payments, health insurance premiums deducted from pay, nontaxable income, educational assistance, and a minister parsonage allowance.

Because the labels are employer defined, two workers at different companies can see very different Box 14 lines even when they have the same underlying benefit. That is normal. It is also why every explanation of Box 14 begins with the same warning: check with your payroll office before assuming what a line means.

2026 change

What Changed About Box 14 for 2026?

Box 14 was revised on the 2026 Forms W-2, W-2AS, W-2GU, W-2VI, and W-2c. The IRS split the single Box 14 into two labeled halves.

• Box 14a, Other: everything that used to appear in the old single Box 14 goes here. The rule and the examples are unchanged.
• Box 14b, Treasury Tipped Occupation Codes: a brand new field, created to work alongside the new Box 12 code TP for cash tips. Employers of tipped workers now report the IRS Tipped Occupation Code that describes the job.

Box 9 on the same form was reduced in width so that Box 14a has more room. That means the printed W-2 in January 2027 for tax year 2026 will look a little different than earlier years, even for employees whose actual pay picture has not changed.

What appears in 14a

What Types of Items Appear in Box 14a?

The IRS gives employers a running list of items that fit in Box 14a. Some are required (a railroad employer must use 14a for RRTA amounts). Most are optional. Common Box 14a entries include:

If your employer included 100 percent of a company car annual lease value in your income, the IRS says that amount must appear in Box 14a (or on a separate statement). This is general information, not tax advice; use the calculator above to see how a pretax item like union dues or health insurance changes take home pay.

Impact on return

Do Box 14 Items Affect Your Tax Return?

Box 14 amounts do not, by themselves, change Box 1, Box 3, or Box 5 wages. Those wage boxes are already computed by the employer before Box 14 is filled in. Whether a Box 14 line affects your return depends on the specific item.

• Already reflected in Box 1: Pretax deductions like a section 125 cafeteria plan health premium reduce Box 1 wages when they are withheld. If the employer also lists them in Box 14a, do not subtract them a second time.
• Deductible on the state return: State disability insurance (SDI) contributions and some state Paid Family Leave amounts may be deductible as state taxes on Schedule A for taxpayers who itemize. Rules vary by state.
• Adds a follow up form: If Box 14a shows a railroad Tier 1 or Tier 2 amount, the taxpayer may need to attach a related schedule when claiming credits.

When in doubt, enter every Box 14 label into your tax software; most programs recognize common employer labels and route them correctly.

New 14b

What Is Box 14b Used For?

Box 14b is new for 2026 and carries the Treasury Tipped Occupation Code that describes the tipped worker occupation. It ties directly to Box 12 code TP, which reports the total cash tips the employee reported to the employer. Public Law 119-21 (the One Big Beautiful Bill Act) added both fields.

Employer rules for Box 14b:

• Enter up to two occupation codes.
• If tips were received in more than two occupations, pick any two of the three or more.
• If any tips were received in a nonqualifying occupation, one of the codes must be 000.
• The IRS publishes the code list at IRS.gov TippedOccupations.

The link between codes matters at filing time. The individual deduction for qualified tips (up to $25,000 for tax years 2025 through 2028 under P.L. 119-21) applies only to tips received in customarily and regularly tipped occupations on the IRS list. Box 14b tells the IRS which occupation was used to determine that eligibility.

Reading labels

How Do You Read Common Box 14a Labels?

Because each employer picks its own abbreviation, Box 14a is where readers most often get stuck. Here are patterns that repeat across US employers.

• State tax abbreviations: CA SDI (California disability), NY DBL (New York disability), NJ SDI, PA UC, WA PFML. These map to state programs.
• Overtime and tips (2026): Some employers add a companion 14a label such as OT or Tips OT so that federal and state agents can trace the amount in Box 12 code TT or code TP back to a pay line. This is optional; the required code is still in Box 12.
• Retirement side notes: USERRA make up contributions for a prior year and nonelective employer pension amounts are reported in Box 14a per the IRS instructions, not in Box 12.
• Payroll fringe items: LEASE, AUTO, PERS USE (personal use of employer car), BUSMILE (business mileage reimbursement not substantiated), and MOVING (nonqualified moving reimbursements) all show up in 14a.

If a label is not on this list, ask your employer or search the IRS Instructions for Forms W-2 and W-3 for the phrase before you file.

Fixes

What Should You Do If Box 14 Looks Wrong?

Compare each Box 14 line against the year to date columns on your final pay stub. If a line is missing, if an amount is off, or if a label is unclear, ask payroll to explain or correct it. Box 14 errors are less common than Box 1 or Box 12 errors because Box 14 does not change withholding, but a corrected W-2c can still be issued when an employer needs to fix the entry.

Do not file with an unclear Box 14 line unresolved if that line is a state SDI or state PFML entry, because those may affect your state return. For informational lines like union dues or educational assistance, most filers can proceed once they know the label. Keep a copy of any employer explanation in your tax file so that a future audit or amended return has a clean paper trail.

Small typographic differences (an extra space in a label, a shortened code) rarely rise to a W-2c correction. Ask for a W-2c when the amount, the label direction (pretax vs after tax), or the presence of a full item is wrong. Most employers process a corrected W-2 within two weeks of a written request.

Official source

Where Is the Official Box 14 Reference?

The rules for Box 14a and Box 14b are set out each year in the IRS General Instructions for Forms W-2 and W-3. The 2026 edition is posted as iw2w3.pdf on IRS.gov and carries a Jan 29, 2026 revision date. The Treasury Tipped Occupation Code list lives at IRS.gov TippedOccupations. State disability and Paid Family Leave rules come from each state agency, not the IRS; California uses edd.ca.gov, New York uses paidfamilyleave.ny.gov, and New Jersey uses myleavebenefits.nj.gov. Railroad specific reporting rules are covered in the same IRS instructions under Railroad employers.

Bookmark the IRS instructions page. It is updated each January and is the only authoritative source for what an employer must or may report in Box 14a and Box 14b. If a payroll provider or third party guide disagrees with the current iw2w3.pdf, follow the IRS text; the SSA rejects W-2 wage reports that do not follow the current instructions.
