Is Short-Term Disability Taxable? It Depends on Who Paid the Premium

Whether short-term disability is taxable depends on who paid the insurance premium. If your employer paid it, the benefits are taxable income. If you paid it yourself with after-tax money, the benefits are not. If you paid it through a pre-tax payroll deduction, the IRS treats the benefits as taxable. Here is how to tell which situation you are in, and what it means for your check.

Is short-term disability taxable? The three premium scenarios

The IRS looks at who paid for the coverage, and whether tax was already paid on the money used to pay for it. The logic is simple: if you were never taxed on the premium, you are taxed on the benefit. If you were taxed on the premium, the benefit comes to you tax-free. That produces three scenarios.

1. Your employer paid the premium

Per the IRS, you must report as income any amount you receive for your disability through an accident or health insurance plan paid for by your employer. Many employers provide short-term disability as a free benefit. In that case every benefit payment is taxable, the same as wages you earned.

2. You paid through a pre-tax cafeteria plan

This is the case that surprises people. If your premium comes out of your paycheck before taxes through a cafeteria plan and you did not include it in taxable income, the IRS considers the premiums paid by your employer. The disability benefits are then fully taxable. You got the tax break on the way in, so the benefit is taxed on the way out. For background on how that deduction works, see our guide to pre-tax vs post-tax deductions.

3. You paid the premium with after-tax money

If you pay the entire cost on an after-tax basis, you do not include any amounts you receive for your disability as income. IRS Publication 525 says the same thing: if you paid the premiums on an accident or health insurance policy, the benefits you receive under the policy are not taxable.

The split case: employer and employee both pay

Many plans are shared. If both you and your employer paid the premiums and you pay your share on an after-tax basis, only the part of the benefit that is due to your employer’s payments is reported as income. The rest is tax-free. If your share is paid pre-tax, that share counts as employer-paid and the whole benefit is taxable.

A worked example of short-term disability tax treatment

Say a plan pays 60% of a $1,000 weekly salary, so the gross benefit is $600 a week. Here is how much of that is taxable in each scenario.

Who paid the premium	Taxable part of the $600 weekly benefit	Tax-free part
Employer paid all of it	$600	$0
Employee paid all of it pre-tax (cafeteria plan)	$600	$0
Employee paid all of it after-tax	$0	$600
Split: employer paid 70%, employee paid 30% after-tax	$420 (70% of $600)	$180

This example only shows what portion is taxable. It does not calculate any tax, because that depends on your other income and filing details. Plans and insurers determine the exact allocation method for split premiums, so confirm the numbers with your plan.

What it means for the benefit check you receive

As with the gap between gross pay and net pay on a regular check, the amount you receive is not the whole story. A disability payment can arrive with taxes already taken out, with nothing taken out, or with only part of the benefit treated as taxable. A check with no withholding does not mean the money is tax-free. Taxable benefits still belong on your return, and a gap between what was withheld and what you owe shows up when you file.

If nontaxable sick pay was paid to you, it can appear in box 12 of your Form W-2 with code J. That code marks the tax-free portion, so check it against your own records.

Social Security and Medicare on sick pay, and the six-month rule

Income tax is only one piece. The IRS defines sick pay as any amount paid under a plan because of an employee’s temporary absence from work, and sick pay is usually subject to Social Security, Medicare and FUTA taxes. Two exceptions matter:

• Payments, or parts of payments, attributable to your own contributions to the sick pay plan made with after-tax dollars are not subject to those taxes.
• Sick pay paid more than six calendar months after the last calendar month in which you worked for the employer is not subject to those taxes.

Here is how the six-month rule works. Suppose your last day worked was in March. The six calendar months after March are April, May, June, July, August and September. Sick pay paid after September 30 is no longer subject to Social Security and Medicare taxes. Sick pay paid on or before that date still is.

If you go back to work, even briefly, the clock starts over. Working one day in a later month means the six months are counted from that month instead.

Withholding: employer-paid vs third-party insurer, and Form W-4S

Whether tax is taken out of your benefit depends on who is paying it.

• Sick pay paid by your employer, or by an agent acting for the employer, is subject to mandatory federal income tax withholding. A third party that pays as the employer’s agent is not considered the employer, but the withholding rule still applies to the payments.
• For sick pay paid by a third party that is not acting as your employer’s agent, such as many insurance companies, you are not required to have federal income tax withheld. You can choose to have it withheld.

How Form W-4S works

To request withholding from a third-party payer, give it Form W-4S (2026), Request for Federal Income Tax Withholding From Sick Pay. Do not use it if your employer or its agent makes the payments. Key points:

• You request a flat dollar amount per payment, not a percentage.
• The amount must be at least $4 per day, $20 per week or $88 per month, based on your payroll period.
• It must not reduce the net amount of each payment below $10.
• It stays in effect until you change or revoke it. To revoke it, complete a new Form W-4S and write “Revoked” in the money amount box.

If you decline withholding, plan ahead. To avoid a penalty, have enough tax withheld or make estimated tax payments using Form 1040-ES. Our guide to estimated taxes and who needs to pay quarterly covers the process, and the underpayment penalty explains what happens if you fall short. Another option is to raise withholding at a job you or your spouse still hold, using the steps in our guide on how to fill out a W-4.

Is workers comp taxable? And long-term disability?

Short-term disability from a private plan is a different animal from other kinds of disability income, so the answer to “is disability income taxable” changes with the source.

Workers’ compensation

The answer to “is workers comp taxable” is generally no. Workers’ compensation for an occupational sickness or injury paid under a workers’ compensation act or similar law is not taxable. Payments for a work-related injury or sickness under a workers’ compensation law are not sick pay, and they are not subject to employment taxes.

Long-term disability pensions

A disability pension from an employer-funded plan is included in income and reported as wages until you reach minimum retirement age, generally the age at which you could first receive a pension if you were not disabled. After that point it is reported as pension or annuity income.

Social Security and state programs

Social Security benefits may be partly taxable depending on your other income. SSI is not taxable. State disability programs, such as those in California, New York and New Jersey, have their own tax treatment, so check your state program’s guidance.

Checklist: how to find out how your premium is paid

Do not guess. Confirm it before you file a claim, or at least before you file your return.

• Check your pay stub. Look for a short-term disability deduction and see whether it is labeled pre-tax or post-tax. If there is no deduction at all, your employer likely pays. Our guide on how to read your pay stub shows where to look.
• Open your benefits portal. Enrollment records often show the cost to you and whether it is deducted pre-tax or after-tax.
• Read the plan summary. The summary plan description or certificate of coverage usually states who pays the premium and how.
• Ask HR or the insurer. For a split plan, ask how the taxable share is figured and how withholding will be handled.
• Check prior years. If the deduction was pre-tax in some years and after-tax in others, the answer can differ by claim.

The open enrollment decision: paying the premium after-tax

If your employer offers a choice, the pre-tax or after-tax election is one of the more consequential small choices at open enrollment. Paying the premium after-tax means a slightly smaller paycheck now, but the benefit is not taxed if you ever need it. Paying pre-tax means a slightly larger paycheck now, but the benefit is fully taxable later.

There is no universal right answer. Some people prefer the larger paycheck today. Others would rather protect the full benefit during a period when income is already reduced. The same trade-off shows up across your benefits, as in which election saves more. Your plan documents control what is actually available to you.
