Is back pay taxable income?

The rule

The Back pay awards entry in Publication 525 is three sentences long. You must include in income amounts you are awarded in a settlement or judgment for back pay. These include payments made to you for damages, unpaid life insurance premiums and unpaid health insurance premiums. And they should be reported to you by your employer on Form W-2. The idea behind the rule is straightforward: back pay replaces wages you should have received earlier, so it has the same character as the wages. If the money would have been taxable when paid on time, it stays taxable when it arrives late.

Everything in the award, not just the wage line

People often split a settlement into a wage amount and everything else, hoping the rest is tax free. The publication does not draw that line for back-pay awards. It names damages, unpaid life insurance premiums and unpaid health insurance premiums as parts of the amount you include. When the employer pays a back-pay judgment, ask for the breakdown on the W-2 and make sure the total on your return matches. The general rule is that you include all your pay on Form 1040 or 1040-SR line 1a, even if you do not receive a Form W-2 or the one you receive does not include everything.

Back-pay awards also bring up related employer issues. If an employer did not withhold social security and Medicare taxes from pay for work you performed as an employee, the publication describes filing Form 8919 with your return.

A different kind of award

Back pay should not be confused with other settlement payments the publication lists separately under Court awards and damages. For example, it says payments received for personal physical injuries or physical sickness are not taxable, including emotional distress attributable to those injuries, while payments for emotional distress that are not attributable to a physical injury or sickness are taxable. It also lists back pay and damages for emotional distress received to satisfy a claim under title VII of the Civil Rights Act of 1964 among the items to include. How an award is allocated between wages and other types of damages therefore matters, and the settlement agreement or judgment is the place where that allocation will be found.

Worked example

A judgment awards an employee $18,000 of back pay, $2,500 in damages and $1,200 of unpaid health insurance premiums, plus $300 of unpaid life insurance premiums. All four amounts are included, a total of $22,000, and the employer reports them on Form W-2. The calculator above adds up whatever parts your award contains. Note that the total is the amount received in the tax year of the payment, which may be later than the years the pay was due; the publication does not give a special averaging method, so do not assume one applies. If you receive a settlement spread over more than one year, each year’s payments are reported when you receive them.

Limits and next steps

Keep the settlement paperwork. The judgment or agreement shows what the award replaces, and the publication says that to decide whether a settlement is included you must consider the item it replaces, because the character of the income depends on the nature of the underlying claim. A payment that replaces wages looks different from one that replaces a physical injury, so the allocation in the document is the first thing a preparer will ask for. This page covers only what Publication 525 says about back pay awards. It does not address attorney fees, legal-fee deductions or the treatment of lawsuits that are not employment matters. For a rough sense of how a big one-time amount stacks on top of your regular income, check the federal tax brackets and the bonus tax calculator for the withholding side. If tax is not withheld on a large payment, you may owe estimated tax, so see the estimated tax due dates.
