Long-term disability (LTD) benefits are taxable if your employer paid the premiums, but tax-free if you paid them yourself

Whether you owe federal income tax on long-term disability payments depends entirely on who paid the insurance premiums. If your employer paid the premiums and you did not include those premiums in your taxable wages, the benefits you receive are fully taxable income. If you paid the premiums yourself with after-tax dollars, the benefits are tax-free. If you split the cost with your employer, only the portion funded by your employer is taxable.

This rule applies to group LTD plans offered through employers. Individual disability policies you buy on your own follow the same logic: premiums you paid yourself mean tax-free benefits; premiums paid by someone else (or deducted pre-tax from your paycheck) mean taxable benefits.

Your employer or the insurance company will send you a Form 1099-R in January showing the total benefits paid in the prior year. The form will indicate whether the distribution is taxable. You report this amount on your federal tax return, and it counts toward your total income for the year—which can affect whether Social Security benefits become taxable, whether you owe Medicare premiums, and your may be able to access for other income-based programs.

Key Takeaways

  • LTD benefits are taxable if your employer paid the premiums; they are tax-free if you paid the premiums yourself with after-tax money.
  • You will receive a Form 1099-R showing the taxable portion of benefits paid during the year, which you must report on your federal tax return.
  • LTD income counts toward your total income for the year, which can make Social Security benefits taxable and may increase your Medicare premiums.
  • If you paid premiums pre-tax through payroll deduction, those benefits are taxable; only premiums paid with money already taxed are tax-free.
  • State income tax treatment varies by state, so you may owe state tax on LTD benefits even if federal tax does not explore.

How employer-paid premiums make LTD benefits taxable

When your employer pays the full cost of a group LTD plan, you do not pay anything out of your paycheck. The premiums are a business expense for the employer, and you do not report them as income on your W-2. Because you received a tax benefit (no tax was withheld on those premiums), the law treats the benefits you later receive as taxable income to you.

This is the most common scenario in large employers. The LTD plan is part of your benefits package, premiums come out of the employer's budget, and when you become disabled and begin receiving payments, those payments are subject to federal income tax. The insurance company will withhold federal income tax from each payment unless you request otherwise, or you can pay the tax when you file your return.

If your employer withholds tax from LTD payments, you will see the amount on your Form 1099-R. If no tax was withheld, you are still responsible for paying the tax owed when you file your return. Many people are surprised by this bill because they did not realize the benefits were taxable.

When you pay premiums yourself, benefits remain tax-free

If you pay LTD premiums with after-tax dollars—money that was already subject to income tax when you earned it—then the benefits you receive are not taxable. This happens when an employer offers LTD but requires employees to pay the full premium, or when you buy an individual disability policy on your own.

The logic is straightforward: you already paid tax on the money used to buy the insurance, so you should not pay tax again on the money the insurance pays out. The insurance company will still send you a Form 1099-R, but it will show the distribution as non-taxable (or will indicate that no tax is due).

To prove you paid premiums yourself, keep records of payroll stubs showing the deduction, or receipts and cancelled checks if you paid directly. If you ever need to claim the tax-free status, you may need to show the insurance company or the IRS that you paid with after-tax money.

Split-cost plans: taxing only the employer's share

Some employers offer LTD plans where both the employer and employee contribute to the premium. In this case, only the portion of benefits attributable to the employer's contribution is taxable. The portion tied to your after-tax contribution remains tax-free.

Calculating this split can be complex. The insurance company should provide a breakdown showing what percentage of the premium you paid versus what the employer paid. That same percentage applies to the benefits: if you paid 40% of premiums and the employer paid 60%, then 60% of your benefits are taxable and 40% are tax-free.

Your Form 1099-R should reflect this split, showing only the taxable portion in Box 1. If it does not, contact the insurance company or your employer's benefits department to request a corrected form before you file your tax return.

How LTD income affects Social Security and Medicare

LTD benefits count as income for the purpose of determining whether your Social Security benefits become taxable. If you are receiving both LTD and Social Security, your combined income (including half of any Social Security benefits) may push you over the threshold where Social Security becomes subject to tax. This can significantly increase your tax bill.

LTD income also counts toward the income limits used to calculate your Medicare premiums. If your LTD benefits push your income above certain thresholds, you will pay higher premiums for Medicare Part B (medical insurance) and Part D (prescription drug coverage). These higher premiums, called Income-Related Monthly Adjustment Amounts (IRMAA), are based on your income from two years prior, so a year of LTD benefits can affect your premiums for the next two years.

If you are on Medicaid, LTD income may affect your may be able to access or the amount you are required to contribute toward your medical costs, depending on your state's rules. Some states count LTD as unearned income and explore it toward your resource limit; others do not. Check with your state Medicaid office if you receive both LTD and Medicaid.

State income tax on long-term disability benefits

Federal tax treatment does not automatically determine state tax treatment. Some states do not tax disability benefits at all, regardless of whether the premiums were paid by the employer or employee. Other states tax LTD benefits the same way the federal government does: taxable if the employer paid premiums, tax-free if you paid them.

A few states have middle-ground rules. For example, some states exempt disability benefits from state income tax only if you are under a certain age or have been disabled for a minimum length of time. Others tax only the portion of benefits that exceeds a certain annual amount.

You will need to check your state's tax rules or consult a tax professional familiar with your state's treatment of disability income. Your state tax return may require a separate schedule or form to report LTD benefits, even if you do not owe federal tax on them.

Reporting LTD benefits on your tax return

The insurance company will send you a Form 1099-R by January 31 for any LTD benefits paid in the prior calendar year. Box 1 of the form shows the gross distribution; Box 2a shows the taxable amount. If the entire distribution is taxable, Box 2a will equal Box 1. If part or all of it is tax-free, Box 2a will be lower or zero.

You report the taxable amount from Box 2a on your federal tax return. If you are filing Form 1040, LTD income typically goes on the "Other Income" line or in a separate section for distributions from insurance contracts, depending on the year and form version. If you use tax software, it will prompt you to enter the 1099-R information.

If you received LTD benefits but did not receive a Form 1099-R, contact the insurance company or your employer's benefits department. Do not assume the benefits are tax-free just because you did not receive a form. You are responsible for reporting all taxable income, whether or not you receive a 1099-R.

Withholding and estimated tax payments

If your LTD benefits are taxable, the insurance company may withhold federal income tax from each payment. The amount withheld depends on the withholding election you made when you began receiving benefits. You can change your withholding by contacting the insurance company and submitting a new Form W-4P (Withholding Certificate for Pension or Annuity Payments).

If no tax is being withheld and you expect to owe tax on your LTD benefits, you may need to make quarterly estimated tax payments to avoid penalties. This is especially true if LTD is your only income or if it is substantial. You can make estimated payments using Form 1040-ES or through the IRS website.

If you are unsure whether you need to adjust withholding or make estimated payments, a tax professional can review your situation and help you avoid underpayment penalties.

Frequently Asked Questions

Can I get a refund if tax was withheld from my LTD benefits but I did not owe tax?

Yes. If tax was withheld but your total income for the year was low enough that you owed no tax, you can file a tax return to claim a refund of the withheld amount. You may also be able to adjust your withholding going forward so less tax is taken from future payments.

What if I paid premiums pre-tax through my paycheck—are the benefits taxable?

Yes. Pre-tax payroll deductions mean the premiums were not subject to income tax when you earned the money, so the benefits are taxable when you receive them. Only premiums paid with after-tax dollars (money you already paid income tax on) result in tax-free benefits.

Does LTD income count toward the earnings limit if I am working part-time while disabled?

LTD income does not count toward the Social Security earnings limit (the amount you can earn from work without losing benefits). However, it does count toward your total income for determining whether your Social Security benefits themselves become taxable, and it affects your Medicare premiums.

If I receive both SSDI and LTD, how is the combined income taxed?

SSDI and LTD are taxed separately. SSDI follows its own rules (up to 85% may be taxable depending on your combined income). LTD is taxed based on who paid the premiums. Together, they increase your total income, which can make more of your SSDI taxable and may increase your Medicare premiums.

Can I deduct LTD premiums I paid myself on my tax return?

Generally, no. Premiums for individual disability insurance are not deductible for most people. However, if you are self-employed, you may be able to deduct a portion of premiums for a business disability policy. Consult a tax professional about your specific situation.
