Misc Non-Taxable Comp on a W-2 is a label your employer chose for one or more benefits that are already excluded from your taxable wages. You’ll find it in Box 14, a freeform space where employers can describe payments and benefits that don’t add to the income you owe federal tax on. Because the amount is already left out of Box 1, you generally don’t have to do anything with it when you file.
Why the Label Looks Vague
Box 14 has no required format. The IRS lets employers use it to report “nontaxable income” and a range of other items such as state disability insurance withholdings, union dues, uniform payments, and educational assistance payments, and it lets them pick their own labels for each entry.1IRS. 2026 General Instructions for Forms W-2 and W-3 That’s why the wording varies so much from one W-2 to the next. One company writes “Misc Non-Taxable Comp,” another writes “NT Benefits” or “Other Nontaxable,” and none of those phrases has an official IRS definition behind it.
Contrast that with Box 12, where the IRS assigns standardized letter codes for specific items. Box 14 is deliberately flexible, which is useful for employers and confusing for employees.
What’s Usually Bundled Under the Label
What sits behind the number depends on your employer. Common excluded benefits that get grouped into a Box 14 “non-taxable” line include employer contributions toward parking or transit passes, educational assistance, wellness program reimbursements, and various other fringe benefits that qualify for statutory tax exclusions.
A few of those have specific dollar limits worth knowing. Qualified transportation benefits are excludable up to $340 per month for 2026 for transit passes and commuter vehicle transportation, and qualified parking has the same $340 monthly cap.2Internal Revenue Service. Publication 15-B Employer’s Tax Guide to Fringe Benefits Educational assistance under a qualifying program is excludable up to $5,250 per calendar year for 2026, covering tuition, fees, books, and similar expenses.3Office of the Law Revision Counsel. 26 USC 127 – Educational Assistance Programs Some employers report these in Box 14 for your reference; others don’t report them anywhere on the W-2 because the exclusion is complete.
Dependent care assistance can also end up in Box 14 as an informational reference, though its official home on the form is Box 10.
How to Find Out Exactly What’s In It
The fastest way to identify what your employer stacked into the “misc non-taxable” figure is to ask your payroll department or HR office. They can break the number down by benefit. That detail matters in two situations: when you’re reconciling your pay stubs against your W-2, and when you file in a state that treats a particular benefit differently from the federal government. Some states don’t follow the federal exclusion rules for every fringe benefit, so a line that’s non-taxable federally could still be taxable at the state level.
Why the Amount Doesn’t Change Your Taxable Wages
Federal tax law defines gross income broadly, covering compensation for services, fringe benefits, and similar items “from whatever source derived.”4Office of the Law Revision Counsel. 26 USC 61 – Gross Income Defined Non-taxable compensation exists because Congress carved out statutory exclusions for specific benefits. When a benefit qualifies, your employer removes its value from Box 1 before the W-2 is generated. The Box 14 entry is a description of something that has already been subtracted; it isn’t a second amount you need to subtract yourself.
One nuance worth knowing: not every excluded benefit is excluded from every wage box. A fully excluded benefit like an employer HSA contribution or dependent care assistance within the annual cap comes out of Boxes 1, 3, and 5. A pre-tax retirement deferral like a traditional 401(k) contribution comes out of Box 1 but stays in Boxes 3 and 5, because Social Security and Medicare taxes still apply.5Internal Revenue Service. Retirement Plan FAQs Regarding Contributions – Are Retirement Plan Contributions Subject to Withholding for FICA, Medicare or Federal Income Tax? For a Box 14 line labeled as non-taxable, though, the FICA question usually only matters if you’re trying to match your pay stubs number by number.
Don’t Confuse Box 14 With Box 10 or Box 12
Two other places on the W-2 also report amounts that aren’t part of your taxable wages, and it’s worth keeping them straight so you don’t double-count anything.
Box 10 reports employer-provided dependent care assistance. For 2026, you can exclude up to $7,500 ($3,750 if married filing separately) from gross income, an increase from the $5,000 cap that applied in prior years.6Office of the Law Revision Counsel. 26 USC 129 – Dependent Care Assistance Programs Amounts within the limit are excluded from Boxes 1, 3, and 5, and any excess is added back into Box 1. If dependent care also appears in Box 14, the Box 10 figure is the one that matters for your return.
Box 12 uses standardized IRS letter codes for specific excluded items such as HSA contributions (Code W), employer health coverage cost (Code DD), retirement plan deferrals (Codes D, E, F, G), adoption assistance (Code T), and non-taxable combat pay (Code Q).1IRS. 2026 General Instructions for Forms W-2 and W-3 These amounts, like Box 14 entries, are already excluded from Box 1 where applicable. Adding them on top of Box 1 is the single most common mistake with non-taxable compensation on the W-2.
If the Number Looks Wrong
If you think a benefit was mislabeled or the dollar amount doesn’t match what you actually received, contact your payroll department before you file. Errors sometimes happen the other way too: an excluded benefit gets accidentally rolled into Box 1, which overstates your taxable income. Either way, your employer needs to issue a corrected Form W-2c along with a Form W-3c transmittal. The Social Security Administration instructs employers to file corrections as soon as possible after discovering the mistake and to give you a copy promptly.7Social Security Administration. Helpful Hints to Forms W-2c/W-3c Filing Don’t file a return using a W-2 you know is wrong. Catching the problem before you file saves you from paying tax you don’t owe and then having to amend later.
What to Do at Filing Time
For most people, the answer is: nothing. Enter your W-2 as it appears. Box 1 already reflects the exclusion, and your tax software will handle any Box 10 or Box 12 entries automatically. Box 14 amounts are informational for federal purposes, though your state return may need a specific entry from Box 14 for items like state disability insurance withholdings or paid family leave contributions.
If you prepare your return by hand, the rule to remember is that you don’t add Box 14 non-taxable compensation to your Box 1 wages. It’s already out. Treat the label as a note from your employer explaining what’s not there, not a number you owe tax on.
