How PTO Cash-Outs Are Taxed

The IRS treats vacation and PTO payouts as supplemental wages. Under IRS Publication 15 (Circular E), Section 7, employers withhold federal income tax on supplemental wages using one of two methods: flat or aggregate. The flat method applies a single 22% rate to the payout when it's paid as a separate check, with a higher 37% rate on any portion above $1,000,000 in a calendar year.

FICA always applies. Social Security is 6.2% (up to the 2026 wage base of $176,100) and Medicare is 1.45%, totaling 7.65% per IRS Publication 15, Section 9. Higher earners owe an Additional Medicare Tax of 0.9% on wages above $200,000 for single filers; employers withhold it once year-to-date wages cross that threshold. State income tax stacks on top wherever a state imposes it.

Here's the common surprise: 22% feels high, but it's only withholding. Your final tax bill gets settled when you file your federal return. Filers whose marginal bracket falls below 22% recover the difference as a refund. Filers above 22% may owe more.

State PTO Cash-Out Mandates

Federal law does not require employers to pay out accrued vacation. States set the rule. Eight states treat accrued vacation as earned wages and require payout at separation: California, Colorado, Illinois, Louisiana, Massachusetts, Montana, Nebraska, and North Dakota. In these states, your employer cannot withhold accrued PTO from your final paycheck, no matter the reason for separation.

Four states (California, Colorado, Montana, Nebraska) go further and ban use-it-or-lose-it forfeiture outright. Illinois allows the policy but still mandates payout at separation. Everywhere else, payout depends on what your employer's written policy says. Indiana, Maine, Maryland, New Mexico, New York, and West Virginia all make payout conditional on the handbook or offer letter.

State supplemental withholding rates vary too. California uses 6.6% for vacation and bonus payouts (10.23% for stock options). Colorado uses 4.4%, Illinois 4.95%, Montana 5.0%. Nine states (Texas, Florida, Washington, Nevada, Tennessee, South Dakota, Wyoming, Alaska, New Hampshire) have no state income tax on wages, so the state field defaults to 0%.

When PTO Is Paid Out: Separation, Year-End, and Buy-Back Programs

Most cash-outs happen at separation, but that's not the only trigger. Year-end mandatory cash-outs keep balances from piling up past a cap. Buy-back or sell-back programs let employees voluntarily convert a fraction of unused PTO to cash, often at a discount (commonly 50-80% of face value). Tax treatment is identical in all three cases: supplemental wages, 22% federal flat plus FICA plus state.

Timing affects how much actually hits your bank account. A separate-check payout uses the flat 22% method by default. A payout combined with your regular paycheck (aggregate method) uses your W-4 tables, which can produce higher withholding if the combined check pushes the period's income into a higher bracket. Ask your payroll department which method they use before the payout if you'd rather avoid a withholding surprise.

Strategies to Reduce Withholding Shock

Time the payout. Cashing out in a year when your other income is lower (a sabbatical, parental leave, or partial-year work) can mean a refund at filing time because your marginal bracket sits below 22%. Cashing out in a high-bonus year may compound withholding, though it doesn't change your underlying tax liability.

Adjust your W-4. If you know a large cash-out is coming, file a new W-4 with reduced withholding on your regular paycheck so cumulative withholding for the year matches your expected liability. The IRS Tax Withholding Estimator helps with the math.

Consider a 401(k) deferral if your plan allows it. Some employers permit deferring part of a PTO payout into a retirement account, which reduces current taxable wages. Not every plan permits this, so check the summary plan description before relying on it. Tracking your accruals throughout the year with a tool like Timeclock44 makes any of these strategies easier because you always know what the payout will be worth.
