Long-term disability is usually not taxable, but the tax depends on who paid the premiums

Whether you owe federal income tax on long-term disability (LTD) payments depends entirely on who paid the insurance premiums. If you paid the premiums with after-tax dollars, the benefits are tax-free. If your employer paid the premiums and did not include them in your taxable wages, the benefits are fully taxable income. If you and your employer split the cost, part of the benefit is taxable and part is not.

This rule applies to all long-term disability insurance, whether it is through your job, a union, a professional association, or a policy you bought on your own. The IRS does not care whether the disability is work-related or not — only who paid for the coverage matters.

Long-term disability is separate from Social Security Disability Insurance (SSDI). SSDI has its own tax rules based on your total income, not on who paid premiums. If you receive both LTD and SSDI at the same time, each is taxed under its own rules.

Key Takeaways

  • If you paid the premiums yourself with after-tax money, your long-term disability payments are not taxable.
  • If your employer paid the premiums and you did not report them as income on your W-2, the full benefit amount is taxable.
  • When premiums are split between you and your employer, you owe tax only on the portion your employer paid.
  • You will receive a Form 1099-R from the insurance company showing the total benefit paid; you must report the taxable portion on your federal return.
  • State income tax rules vary — some states do not tax disability benefits at all, while others follow the federal rule.

How to tell whether your premiums were paid with after-tax or pre-tax dollars

Check your most recent pay stub or benefits summary from your employer. If the long-term disability premium appears as a deduction after federal income tax is calculated, it was paid with after-tax dollars and your benefits will be tax-free. If it appears before income tax is calculated, or if it is listed under "pre-tax deductions" or "Section 125 plan deductions," it was paid with pre-tax dollars and your benefits will be taxable.

If you no longer have access to old pay stubs, contact your employer's human resources or benefits department and ask whether your long-term disability premium was deducted before or after taxes. They can tell you definitively. If you bought the policy yourself outside of work, you paid with after-tax dollars and owe no tax on the benefit.

Keep this information. When you file your tax return, you will need to know the breakdown so you can report only the taxable portion. If the insurance company sends you a Form 1099-R that shows the entire benefit as taxable, you may need to attach a letter to your return explaining that part of it was paid with after-tax premiums.

What happens when your employer paid the premiums

If your employer paid the full cost of the long-term disability insurance and did not include the premium in your taxable wages, the entire benefit you receive is taxable income. You must report it on your federal tax return for the year you receive it, even if you receive it over multiple years.

The insurance company will send you a Form 1099-R showing the total amount paid. Report this amount on line 5b of your Form 1040 (or the equivalent line on your state return). You may owe federal income tax, and depending on your state, state income tax as well.

This can create a large tax bill in the year you start receiving benefits, because the first payment often includes back pay covering the months between when your disability began and when the benefit was approved. If you expect a big payment, ask the insurance company whether you can spread it over two calendar years, or ask your tax preparer about estimated tax payments to avoid a surprise bill.

Split-cost premiums and the pro-rata rule

When you and your employer both contributed to the premium, the IRS applies a pro-rata rule: the taxable portion of your benefit equals the employer's share of the total premiums paid over the life of the policy.

For example, if your employer paid 60 percent of all premiums and you paid 40 percent, then 60 percent of every benefit payment is taxable and 40 percent is tax-free. This calculation is done by the insurance company or your employer, not by you — ask them for the exact percentage before you file your return.

If you cannot find this information, the insurance company must provide it when you request a Form 1099-R. The form itself may not break out the split, so you may need to write a note with your tax return explaining the calculation, or work with a tax preparer who can document it.

Reporting the benefit on your tax return

The insurance company will send you a Form 1099-R by January 31 of the year after you receive the benefit. Box 1 shows the total amount paid. Box 2a shows the taxable amount (if the company has that information). If Box 2a is blank or incorrect, you are responsible for calculating and reporting the correct taxable portion.

Report the taxable amount on your Form 1040. The line number depends on your situation: if the benefit is a periodic payment (monthly or regular installments), it goes on line 5b as "other income." If it is a lump sum, it may go on line 5b or line 21, depending on the form year. Your tax software or preparer can direct you to the right line.

Keep records of your premium payments and any documentation from your employer or the insurance company showing the split between your contribution and the employer's contribution. If the IRS questions your return, you will need to show that you paid part of the premium with after-tax dollars.

State income tax on long-term disability

Federal tax rules explore in every state, but state income tax rules vary widely. Some states — including California, New York, and New Jersey — do not tax disability benefits at all, regardless of who paid the premiums. Other states follow the federal rule exactly. A few states have rules in between.

Check your state's tax authority website or ask a tax preparer familiar with your state. If you moved to a different state after you started receiving benefits, you may owe tax to one state but not the other, depending on when the payment was made and where you lived when you received it.

Long-term disability versus SSDI: different tax rules

If you receive both long-term disability and SSDI, each is taxed separately. Your LTD is taxed under the premium-payment rule described above. Your SSDI is taxed only if your "combined income" (SSDI plus half of SSDI plus other income) exceeds a threshold — $25,000 for a single filer, $32,000 for married filing jointly. Below that threshold, SSDI is tax-free.

Many people who receive LTD also receive SSDI because they applied for both when they became disabled. The two benefits often overlap for a period, and some insurance policies reduce the LTD payment by the amount of SSDI received. Ask your LTD insurance company and your Social Security representative to explain how the two interact in your case.

When you file your tax return, you will report the taxable portion of your LTD on one line and your SSDI on another. They do not reduce each other for tax purposes — you calculate the tax on each separately and add them together.

Frequently Asked Questions

Do I owe taxes on long-term disability if I paid the premiums myself?

No. If you paid the premiums with after-tax dollars — either through payroll deduction after taxes were withheld, or by buying a policy on your own — the benefits are not taxable. You do not report them on your federal return.

What if I don't know whether my employer paid the premium?

Contact your employer's benefits or payroll department and ask whether the long-term disability premium was deducted before or after federal income tax. They have records going back years. If you cannot reach them, the insurance company can tell you based on the policy records.

Will I receive a tax form for my long-term disability benefit?

Yes. The insurance company will send you a Form 1099-R by January 31 showing the total benefit paid. Box 2a may show the taxable amount, but if it is blank or wrong, you must calculate and report the correct amount yourself.

Can I reduce my tax bill by spreading the long-term disability payment over two years?

Not automatically. The benefit is taxable in the year you receive it. However, some insurance companies allow you to request that a lump-sum payment be split across two calendar years. Ask your insurance company before the payment is made. If you receive a large back-pay amount, talk to a tax preparer about whether estimated tax payments would help.

Is long-term disability taxable in my state?

It depends on your state. Some states (California, New York, New Jersey, and others) do not tax disability benefits at all. Others follow the federal rule. Check your state tax authority's website or ask a tax preparer in your state.
