Do You Have to Pay Taxes on Short Term Disability?

Whether you owe taxes on short term disability benefits comes down to one question: who paid for the insurance policy. If your employer paid the premiums, your benefits are taxable as ordinary income. If you paid the premiums yourself with after-tax dollars, the benefits arrive tax-free. When the cost is split, the tax treatment splits along the same lines.¹

Who Paid the Premium Controls the Tax

When your employer covers 100% of the disability insurance cost, every dollar you receive while on leave is taxable income, treated the same as a regular paycheck.¹ The logic: your employer’s premium contributions were excluded from your income at the time they were made, so the IRS collects when the benefits are paid out.

Pay the full premium yourself with after-tax dollars, and the benefits are completely tax-free.² You already paid tax on the money that bought the coverage, and the IRS doesn’t tax it twice.

If you and your employer share the cost, the benefits split proportionally. Say your employer pays 60% of the premium and you pay 40% with after-tax money: 60% of any benefit you receive is taxable, and 40% is tax-free.¹ Your HR department or the insurance carrier can tell you the split if your enrollment paperwork doesn’t spell it out.

The Pre-Tax Paycheck Deduction Trap

This is where people get caught off guard. If your disability premium comes out of your paycheck through a cafeteria plan (a Section 125 plan) before taxes, the IRS treats it as if your employer paid. The premium was never included in your taxable income, so the benefits are fully taxable when you collect them.¹

The reverse also holds. If your cafeteria plan included the premium amount in your taxable wages, you’re treated as having paid with after-tax dollars, and the benefits come back tax-free.² Look at a pay stub. See whether the disability premium deduction appears before or after tax withholding. That single line determines whether your benefits will be taxed.

If You Are Self-Employed

Bought your own disability policy as a self-employed person? The benefits are tax-free.¹ You paid the premiums with after-tax money, and the same rule that protects employees who pay their own premiums applies to you.

You cannot deduct those disability insurance premiums as a business expense. Unlike health insurance premiums, disability premiums don’t come off on Schedule C. That’s the trade-off: because you don’t get a deduction going in, the benefits arrive tax-free coming out.

Workers’ Compensation Follows a Different Rule

Don’t confuse short-term disability with workers’ compensation. Workers’ comp benefits are always tax-free, regardless of who paid the premiums, because federal law specifically excludes them from gross income.³ Workers’ comp only covers injuries and illnesses that arise out of your job. Short-term disability covers non-work conditions too. If both are paying you at once, each stream follows its own rules.

Social Security and Medicare Taxes

Income tax isn’t the only tax that can hit your benefits. Short-term disability payments are subject to Social Security and Medicare (FICA) taxes for six calendar months after the last month you actually worked. After that window, the payments stop being wages for FICA purposes.⁴

One trap worth knowing: if you briefly return to work and then go back on disability, the six-month clock resets. Even a single day back on the job starts the count over.⁵

How the Benefits Get Reported

The form you receive depends on who paid. When your employer pays the benefits directly or funds them through a company plan, the taxable amount shows up on your Form W-2 in Box 1, right alongside your regular wages.⁶

When a third-party insurance carrier pays, your employer may still issue the W-2 if the carrier notifies them in time; otherwise the carrier prepares the W-2 itself.⁶ Some third-party payments are reported on Form 1099-MISC in Box 3 instead.

If you paid part of the premium with after-tax money and some of your benefit is nontaxable, the nontaxable portion should show up in Box 12 of your W-2 with Code J.⁶ Hang on to your pay stubs and benefit statements. Errors here are common, because the premium-split calculation depends on records your employer and the carrier don’t always reconcile.

Avoiding a Tax Bill You Didn’t Plan For

When a third-party insurer pays your taxable benefits, federal income tax usually isn’t withheld automatically. A few months of untaxed disability payments can produce a real bill at filing time. You have two ways to stay ahead of it.

File Form W-4S with your insurance carrier to request federal income tax withholding from each payment. The withheld amount has to be at least $4 per day, $20 per week, or $88 per month, and it can’t drop your net payment below $10. You can change or revoke it any time by submitting a new form.⁷

The other option is making quarterly estimated tax payments to the IRS. For 2026, you generally need to pay estimated tax if you expect to owe $1,000 or more after subtracting withholding and credits. To avoid an underpayment penalty, pay at least 90% of your current year’s tax or 100% of last year’s tax (110% if your prior-year adjusted gross income was over $150,000).⁸

Most short-term disability policies replace somewhere between 40% and 70% of your regular income. If that money is taxable and nothing is being withheld, set up withholding or estimated payments early in your leave. It’s much easier than sorting it out in April.

State Taxes Don’t Always Match

State rules don’t always mirror federal treatment. Some states fully exempt disability benefits. Others follow the federal premium-payer approach. A handful of states run mandatory state disability programs funded by employee payroll deductions, and the federal treatment of those benefits still depends on whether the employer also contributes. In states where the employer shares the cost, the employer-paid portion of benefits can be taxable federally even when the state exempts it. Check with your state’s tax authority, or a tax professional, if you’re unsure how your state handles disability income.
