Long-term disability benefits typically last until you reach full retirement age, return to work, or no longer meet the medical criteria for disability — whichever comes first.

Unlike short-term disability, which covers weeks or a few months, long-term disability (LTD) is designed to replace income for years. But "long-term" does not mean permanent or unlimited. The actual length depends on three things: your policy terms, your medical condition, and whether you continue to meet Social Security's definition of disability.

If you receive SSDI (Social Security Disability Insurance), your benefits continue as long as your condition prevents substantial work and you do not earn more than the monthly earnings limit. The program does not have a set end date — some people receive SSDI for decades, others for a few years. What matters is whether your condition improves enough that you can work again, or whether you reach full retirement age, at which point SSDI converts to retirement benefits at the same payment amount.

If your LTD comes through an employer plan or private insurance, the policy itself sets the duration. Some plans pay until age 65, others until age 67 or 70. Some have a fixed term — five years, ten years — regardless of age. You need to read your actual policy document to know which applies to you.

Key Takeaways

  • SSDI has no set expiration date but continues only while you cannot work due to your medical condition and meet Social Security's strict definition of disability.
  • Employer and private LTD plans typically end at a specific age (usually 65 or 67) or after a fixed number of years, depending on what your policy states.
  • Your benefits can end before the policy term if your condition improves enough that you can return to work, as determined by a medical review.
  • Reaching full retirement age converts SSDI to retirement benefits; the payment amount stays the same but the program name changes.
  • Work incentives like the Trial Work Period allow you to test your ability to work without when ready losing benefits.

How SSDI Duration Works

SSDI has no expiration date written into the law. You can receive it for two years, twenty years, or your entire life — the program does not cut you off at a predetermined time. What determines how long you receive it is whether your condition continues to prevent you from doing substantial work.

Social Security conducts medical reviews to check whether your condition has improved. The timing depends on how likely your condition is to improve. If you have a condition expected to improve (like a broken back that may heal), Social Security reviews you sooner — sometimes within six to eighteen months. If you have a condition unlikely to improve (like advanced Parkinson's disease), reviews happen less often, sometimes every five to seven years. If your condition is expected to improve but has not, you may receive a "medical improvement not expected" notice, which extends the time between reviews.

If a review finds that your condition has improved enough that you can work, Social Security will end your benefits. But you have protections: the Trial Work Period lets you work and earn any amount for nine months without losing benefits. After that, you enter the Extended Period of may be able to access, which lasts thirty-six months and lets you keep benefits in any month you earn less than the current substantial gainful activity (SGA) limit — roughly $1,550 per month in 2024, though this amount changes yearly.

When SSDI Converts to Retirement Benefits

When you reach your full retirement age — which is 66, 67, or somewhere in between depending on your birth year — your SSDI automatically converts to Social Security retirement benefits. You do not have to do anything; the conversion happens on its own. Your monthly payment amount stays exactly the same.

This matters because it changes which program you are on, but not your income. You remain on Social Security for life. The only difference is that the program is now called retirement rather than disability, and the rules around work change slightly. After full retirement age, you can earn unlimited income without any reduction to your benefits.

How Employer and Private LTD Plans Set Duration

If your long-term disability comes through your employer or a private insurance policy, the policy document itself states when benefits end. There is no federal rule — each plan is different. Some common structures are:

  • Age-based: Benefits end when you reach age 65, 67, or 70. This is the most common structure in employer plans.
  • Term-based: Benefits last for a fixed period — two years, five years, ten years — from the date you became disabled, regardless of your age.
  • To retirement: Benefits continue until you are old enough to claim Social Security retirement benefits, then stop.
  • Lifetime: Rare, but some policies pay until death if you remain disabled. These are expensive and uncommon in new plans.

You can find this information in your Summary Plan Description (SPD), which your employer or plan administrator must provide. If you do not have it, request it in writing — they are required to send it within thirty days. If you have a private LTD policy you purchased yourself, check your policy document or contact your insurance company.

What Happens When Your Benefits End

When your LTD benefits end — whether because you reached the age limit, completed the term, or your condition improved — you lose that income. If you are on SSDI and reach full retirement age, you do not lose income; you straightforward move to the retirement program. But if your employer LTD ends at age 65 and you have not yet reached full retirement age for Social Security, there is a gap.

Some people bridge this gap by claiming Social Security retirement benefits early (as early as age 62), though the payment is permanently reduced. Others return to work if their condition allows. Some have savings or other income sources. There is no automatic transition — you have to plan for it or explore for retirement benefits before your LTD ends.

If your LTD ends because your condition improved, you may be able to return to work. If you cannot work and your condition is still severe, you can explore for SSDI if you have not already, though the process takes months and has strict medical criteria.

Medical Reviews and Continuing Disability

Both SSDI and most employer LTD plans require periodic medical reviews to confirm you still cannot work. For SSDI, Social Security sends you a form asking about your condition, work attempts, and medical treatment. You fill it out and return it with medical evidence. Social Security then decides whether your condition still meets the disability standard.

For employer LTD, your plan administrator may request updated medical records from your doctor. They use these to decide whether you remain disabled under the policy's definition. Some policies define disability narrowly — you cannot do your own job — while others use a broader definition — you cannot do any job you are reasonably suited for. The stricter the definition, the more likely benefits will end.

If you disagree with a decision to end your benefits, you have the right to appeal. For SSDI, you can request reconsideration, then a hearing before an administrative law judge. For employer LTD, your plan document outlines the appeal process, which usually involves submitting additional medical evidence and requesting a review by someone other than the person who made the initial decision.

Work Incentives That Extend Your Ability to Test Work

If you are on SSDI and want to return to work gradually, several programs let you do this without when ready losing benefits. The Trial Work Period is the most important: you can work and earn any amount for nine consecutive months (not necessarily calendar months) without affecting your benefits. This is a true test period — you keep full benefits regardless of earnings.

After the Trial Work Period ends, you enter the Extended Period of may be able to access. For thirty-six months, you keep benefits in any month you earn less than the SGA limit. This gives you time to see whether you can sustain work. If you stop working, you can return to full benefits without reapplying.

There is also the Plan to Achieve Self-Support (PASS), which lets you set aside income and resources for a work goal without affecting your benefits. And the Impairment Related Work Expenses (IRWE) program lets you deduct disability-related costs from your earnings when calculating whether you have exceeded the SGA limit.

Frequently Asked Questions

Can my SSDI benefits be cut off if my condition improves slightly?

No. Social Security must find that your condition has improved enough that you can do substantial work — earning roughly $1,550 per month or more in 2024. A small improvement does not trigger termination. You also have the Trial Work Period and Extended Period of may be able to access to test work without losing benefits when ready.

What happens to my benefits if I reach full retirement age while on SSDI?

Your SSDI automatically converts to Social Security retirement benefits on the same day you reach full retirement age. Your monthly payment stays the same. You remain on Social Security for life, and after full retirement age you can earn unlimited income without any reduction.

If my employer LTD ends at 65 but I am not old enough for Social Security retirement, what do I do?

You can explore for Social Security retirement benefits as early as age 62, though the payment will be permanently reduced. Or you can explore for SSDI if you have not already and meet the medical criteria. Some people return to work if their condition allows, or rely on savings or other income until they reach retirement age.

How often does Social Security review my case to see if I still may have access to?

It depends on how likely your condition is to improve. Conditions expected to improve are reviewed within six to eighteen months. Conditions unlikely to improve are reviewed every five to seven years or longer. If your condition is expected to improve but has not, you may receive a "medical improvement not expected" notice that extends the time between reviews.

Can I appeal if my LTD benefits are terminated?

Yes. For SSDI, you can request reconsideration and then a hearing before an administrative law judge. For employer LTD, your plan document outlines the appeal process, which typically involves submitting additional medical evidence and requesting review by someone other than the original decision-maker.
