Is Long-Term Disability Insurance Taxable? Section 125 Rules for Employers

Long-term disability benefits follow the same pre-tax versus after-tax rule as short-term disability, but a claim that pays out for years changes how FICA tax, SSDI offsets, and plan design interact.

Quick Answer (as of 2026): Long-term disability benefits are taxable income when the premium was paid pre-tax, including through a Section 125 salary reduction, under IRC Section 105(a). Because LTD claims often run for years while FICA wage treatment on disability pay ends after six calendar months under IRC Section 3121(a)(4), most of a long claim's payments escape Social Security and Medicare tax even when the benefit itself stays fully taxable for income tax.

Long-term disability insurance replaces part of an employee's paycheck if a serious illness or injury keeps them out of work for months or years, and whether that replacement paycheck is taxable depends entirely on how the premium was paid. Employers that already offer short-term disability coverage through a Section 125 cafeteria plan often assume long-term disability works the same way. It mostly does, with one major practical difference: because a long-term claim can run for years while a short-term claim resolves in weeks, the FICA tax treatment of the benefit changes partway through a long claim in a way short-term disability rarely encounters.

Long-term disability insurance should not be confused with <a href="/blog/long-term-care-insurance-section-125">long-term care insurance</a>, which IRC Section 125(f) bars from cafeteria plans entirely. Long-term disability, unlike long-term care, can run through Section 125 pre-tax, which is exactly why the mechanics below matter to an employer building an enrollment menu.

Is Long-Term Disability Insurance Taxable?

Long-term disability insurance benefits are taxable to the extent the premium was paid with pre-tax dollars, and tax-free to the extent the employee paid the premium with after-tax dollars. This is the same rule under IRC Section 105(a) that governs <a href="/blog/short-term-disability-insurance-taxable">whether short-term disability insurance is taxable</a>, and it applies to long-term disability whether the premium was paid entirely by the employer or by the employee through a pre-tax payroll deduction.

The rule looks at who bore the economic cost of the premium, not at the label on the policy. A long-term disability premium paid with money the employee never paid income tax on produces a taxable benefit check if that employee later becomes disabled, regardless of how the coverage was marketed at open enrollment.

How Does Section 125 Affect Long-Term Disability Benefit Taxation?

Running a long-term disability premium through a Section 125 cafeteria plan makes the future benefit fully taxable, the same as it does for short-term disability. A pre-tax salary reduction under Section 125 counts as an employer-paid premium under IRC Section 105(a), because the employee never paid federal income tax or FICA tax on that premium dollar.

This tradeoff carries more weight for long-term disability than for short-term disability because of how long the benefit can run. A short-term disability claim usually resolves within weeks. A long-term disability claim can pay out for two years, five years, or until the employee reaches age 65, depending on the policy. Every one of those monthly checks is taxable income if the premium was paid pre-tax, which adds up to a meaningfully larger lifetime tax bill than a short claim ever would. Our <a href="/blog/section-125-cafeteria-plan-2026-guide">Section 125 cafeteria plan guide</a> explains how salary reduction elections work across the rest of a benefits menu.

How Does the FICA Six-Month Rule Apply to a Long-Term Disability Claim?

Long-term disability payments stop counting as FICA wages six calendar months after the last month the employee worked, even though the benefit itself can keep paying out for years. This rule comes from IRC Section 3121(a)(4), which excludes sickness and accident disability payments from Social Security and Medicare wages once six calendar months have passed following the last month of work, regardless of how long the disability payments continue after that point.

This produces a genuinely different outcome than short-term disability. A short-term disability claim that resolves in eight or twelve weeks stays inside the six-month FICA window for its entire duration, so Social Security and Medicare tax applies to the whole benefit period. A long-term disability claim that pays out for two or three years is subject to FICA tax for only the first six calendar months. After that point, the remaining months of payments are still subject to federal income tax if the premium was pre-tax, but they are no longer subject to Social Security and Medicare tax. Employers administering payroll for a long LTD claim need to track that six-month cutoff to stop withholding and remitting FICA tax on payments made after it passes.

How Does the SSDI Offset Affect a Long-Term Disability Benefit?

Many long-term disability policies reduce the monthly LTD benefit dollar-for-dollar by any Social Security Disability Insurance award the employee receives for the same disability. An employee approved for $1,000 a month in SSDI under a policy that pays $1,500 a month in LTD benefits collects a combined $1,500, not $2,500, with the insurer paying only the $500 difference.

The SSDI offset does not change how the LTD benefit is taxed, but it changes who is paying which piece of it and how each piece gets reported. The portion paid by the LTD insurer follows the same pre-tax versus after-tax rule under IRC Section 105(a) as the rest of the benefit. The SSDI portion is a separate federal benefit with its own tax treatment, and up to 85% of Social Security disability benefits can be taxable depending on the employee's combined income under IRS rules for Social Security benefit taxation. Employers should make sure employees understand that an SSDI award often shrinks the actual LTD check even though the total household benefit before tax stays close to what the policy originally promised.

What Is the Difference Between "Own Occupation" and "Any Occupation" Coverage?

Most group long-term disability policies define disability one way for the first 24 months of a claim and a stricter way after that. This is a plan-design detail, not a tax rule, but it directly affects how long an employee can expect to receive the taxable or tax-free benefit HR already explained at enrollment.

During the initial period, usually 24 months, most policies use an "own occupation" standard, meaning the employee qualifies for benefits if they cannot perform the material duties of their specific job, even if they could work in a different field. After that period, most policies switch to an "any occupation" standard, under which the employee must be unable to perform any job reasonably suited to their education and experience to keep receiving benefits. Employers should communicate this switch clearly during enrollment, since it is a common point where employees lose benefits they assumed would continue, and it is unrelated to whether the benefit is taxable.

How Common Is Employer-Sponsored Long-Term Disability Coverage?

Access to employer-sponsored long-term disability coverage, like short-term disability coverage, varies by company size. The Bureau of Labor Statistics tracks long-term disability plan access alongside short-term disability and life insurance in its National Compensation Survey, released September 25, 2025 with March 2025 reference data, and consistently finds that access to every disability benefit category rises sharply with employer size.

For short-term disability specifically, the same BLS survey found 31% of private industry workers at establishments with fewer than 100 employees had access, compared with 68% at establishments with 500 or more employees. Long-term disability coverage follows the same size pattern in BLS data, which makes a small or midsize employer that offers LTD coverage at all worth highlighting to prospective and current employees. See our post on <a href="/blog/maximizing-fica-tax-savings">maximizing FICA tax savings</a> for how the same employer-size pattern shows up across other pre-tax benefits.

Does IRS Form 8922 Apply to Long-Term Disability Benefits?

Yes. Form 8922 applies to long-term disability benefits the same way it applies to short-term disability benefits, whenever a third-party insurer pays the benefit and the liability for the employer's share of FICA tax is transferred between the employer and the insurer. The form reconciles the wages and taxes reported on Form W-2 with what the third-party payer actually withheld and remitted.

Because a long-term disability claim can span multiple calendar years, an employer may need to coordinate Form 8922 reporting with its insurer across more than one filing cycle for a single claim, which is not usually an issue with a short-term disability claim that resolves within one plan year. Employers should confirm with their insurer or third-party administrator which entity is responsible for filing Form 8922 each year a long-term disability claim stays open.

What Should Employers Consider Before Running LTD Premiums Through Section 125?

An employer should decide upfront whether long-term disability premiums will run through the Section 125 plan pre-tax, be paid entirely by the employer, or be offered as a voluntary after-tax payroll deduction outside the cafeteria plan. Because a long-term disability benefit can pay out for years, the tax consequences of that choice compound over a much longer period than they would for short-term disability.

Employers that want to preserve a tax-free benefit for employees who eventually file a long-term claim can structure the premium as an after-tax voluntary deduction, which still runs through payroll but is not a Section 125 qualified benefit. Employers that prioritize simplicity and lower payroll deductions today should make sure open enrollment materials explain, in plain language, that a future long-term disability benefit will be taxable, will lose FICA tax status after six calendar months, and may be reduced by an SSDI offset if the employee also qualifies for Social Security disability.

Frequently Asked Questions

Is long-term disability insurance taxable if my employer pays the premium?
Yes. Under IRC Section 105(a), long-term disability benefits are included in taxable income whenever the premium was paid by the employer, since the employee never paid tax on that premium dollar. This is true whether the employer pays the premium directly or the employee pays it through a pre-tax Section 125 payroll deduction, because both are treated as employer-paid for this rule.
Are long-term disability benefits tax-free if I pay the premium myself?
Yes, if the premium is paid with after-tax dollars. An employee who pays long-term disability premiums with money that has already been taxed receives any resulting benefit tax-free under IRC Section 105(a). This applies whether the employee pays through a voluntary after-tax payroll deduction or pays the insurer directly outside of payroll.
Does running long-term disability premiums through Section 125 always make the benefit taxable?
Yes. A Section 125 salary reduction is a pre-tax election, so the employee never pays income tax or FICA tax on that premium dollar. The IRS treats a pre-tax Section 125 election the same as an employer-paid premium under IRC Section 105(a), which means the resulting long-term disability benefit is fully taxable for income tax purposes if the employee later files a claim.
How does Social Security Disability Insurance affect a long-term disability benefit check?
Many long-term disability policies reduce the monthly LTD benefit dollar-for-dollar by any Social Security Disability Insurance award for the same disability. An employee who is approved for SSDI receives that amount from Social Security, with the LTD insurer paying only the remaining difference up to the policy's stated benefit amount. This offset changes who pays which part of the benefit, but it does not change the underlying pre-tax versus after-tax taxation rule for the LTD portion.
Are long-term disability benefits subject to Social Security and Medicare tax for the entire time a claim is open?
No. Under IRC Section 3121(a)(4), disability payments stop counting as FICA wages six calendar months after the last month the employee worked, even if the benefit itself keeps paying out for years. A long-term disability claim is subject to Social Security and Medicare tax for only its first six calendar months, while a short-term disability claim that resolves within that window stays subject to FICA tax for its full duration.
What is the difference between "own occupation" and "any occupation" in a long-term disability policy?
Most group long-term disability policies pay benefits under an own occupation standard for the first 24 months, meaning the employee qualifies if they cannot perform their specific job. After 24 months, most policies switch to an any occupation standard, requiring the employee to be unable to perform any job suited to their education and experience to keep receiving benefits. This is a plan-design detail separate from the tax rules and is a common point where employees lose benefits they expected to continue.
Does Form 8922 third-party sick pay reporting apply to long-term disability benefits?
Yes. Form 8922 applies to long-term disability benefits the same way it applies to short-term disability benefits, whenever a third-party insurer pays the benefit and FICA tax liability is transferred between the employer and the insurer. Because a long-term disability claim can span more than one calendar year, employers may need to coordinate this reporting with their insurer across multiple filing cycles for a single claim.
Should a small business run long-term disability premiums through its Section 125 plan?
It depends on what the employer wants to accomplish. Running the premium pre-tax through Section 125 lowers the payroll deduction and is simpler to administer, but it makes every future LTD benefit check taxable for as long as the claim runs, which can span years. An employer that wants employees to receive a tax-free benefit during a long-term claim should structure the premium as an after-tax deduction instead, even if that deduction still runs through payroll outside the cafeteria plan.
