Long-term disability and SSDI are separate programs that can pay at the same time

Long-term disability (LTD) is insurance you get through your employer or buy privately. Social Security Disability Insurance (SSDI) is a federal program run by the Social Security Administration. They operate independently — you can receive both, but the way they work together affects how much money you actually take home each month.

The key difference: your employer's LTD plan pays you based on your salary and the terms of your policy. SSDI pays you based on your work history and how much you earned over your lifetime. One does not replace the other, but if you receive both, your LTD payment may be reduced by a formula called an offset.

Understanding how these two programs interact matters because it changes what you will actually receive and when you need to notify each program about the other.

Key Takeaways

  • Long-term disability and SSDI are separate insurance systems — one through your employer, one through Social Security — and you can receive payments from both at the same time.
  • Many employer LTD plans reduce your payment by the amount you receive from SSDI, a practice called an offset, so your total monthly income may not increase even after SSDI approval.
  • You must report your SSDI approval to your LTD plan administrator, and you must report your LTD payments to Social Security when you explore for SSDI.
  • The Social Security Administration will not approve you for SSDI based on a condition your LTD plan already rejected, so LTD denials do not automatically lead to SSDI approval.
  • If your LTD plan ends before you reach retirement age, SSDI becomes your only income source unless you return to work.

How the offset works and what it means for your income

An offset is a reduction to your LTD payment that occurs when you also receive SSDI. The most common offset formula subtracts your SSDI payment from your LTD payment dollar-for-dollar. This means if your LTD plan would pay you $2,000 per month and you then receive $1,200 per month from SSDI, your LTD payment drops to $800 per month — your total remains $2,000.

Not all LTD plans use offsets. Some plans pay the full amount regardless of SSDI. You can find out whether your plan has an offset by reading your plan documents (usually called a Summary Plan Description or SPD) or asking your employer's benefits department directly. The offset language is typically in a section titled "Coordination of Benefits" or "Offsets."

A few plans use a partial offset, reducing your LTD by only a percentage of your SSDI payment rather than the full amount. Others offset only after you reach a certain age, such as 65. The exact terms depend entirely on what your employer negotiated with the insurance company.

When you must tell each program about the other

When you explore for SSDI, the Social Security Administration will ask whether you receive long-term disability payments. You must report this truthfully. Social Security uses this information to verify your income and to coordinate with your LTD plan if needed.

After you are approved for SSDI, you must notify your LTD plan administrator in writing. Send them a copy of your SSDI award letter (the official document from Social Security stating your monthly benefit amount). Your LTD plan needs this to calculate any offset and adjust your payment accordingly.

If your LTD payments change — for example, if your plan ends or your benefit amount increases — you must report this to Social Security within 30 days. Similarly, if your SSDI payment changes, notify your LTD administrator. Failing to report changes can result in overpayments that you may be required to repay.

Whether an LTD denial affects your SSDI chances

A denial from your LTD plan does not automatically mean Social Security will deny you. The two programs use different standards to decide who qualifies. Your LTD plan may deny you because your condition does not meet their specific definition of disability, or because they believe you can still work in some capacity. Social Security uses its own medical criteria and work history rules.

However, if your LTD plan approved you, that can strengthen your SSDI process. An LTD approval shows that an independent insurance company reviewed your medical evidence and agreed you cannot work. Social Security may request your LTD file as part of their review.

The reverse is also true: if Social Security denies you for SSDI, your LTD plan is not automatically affected. Each program makes its own decision based on its own rules.

What happens to SSDI if your long-term disability ends

LTD plans typically end at a specific age, most commonly 65, though some end at 62 or 67. When your LTD payments stop, your SSDI does not automatically stop — it continues as long as you remain disabled according to Social Security's standards and you do not return to substantial work.

At age 65 or 66 (depending on your birth year), your SSDI converts to retirement benefits at the same payment amount. This is not a new process; it happens automatically. Your monthly payment stays the same, but the program name changes from SSDI to Social Security Retirement Insurance.

If you return to work before your LTD ends, you may lose both programs. Returning to work that Social Security considers "substantial" (currently more than $1,550 per month in earnings, though this amount changes yearly) can end your SSDI. Your LTD plan may also have a "return to work" clause that stops payments if you earn above a certain threshold.

How to coordinate benefits if you have both programs

Start by gathering your plan documents. Request your LTD plan's Summary Plan Description from your employer's human resources or benefits department. This document explains your offset policy, when payments end, and what you must report.

Next, contact your LTD plan administrator and ask three specific questions: Does your plan offset SSDI payments? At what age do LTD payments end? What documentation do they need when you are approved for SSDI? Write down the answers and keep them with your records.

When you explore for SSDI, have your LTD award letter and most recent benefit statement ready. Social Security will ask for these. After you are approved for SSDI, send your SSDI award letter to your LTD administrator when ready — do not wait for them to ask. Keep copies of everything you send.

If your LTD plan reduces your payment after SSDI approval, ask for a written explanation of the offset calculation. Verify the math is correct. If you believe the offset was applied incorrectly, contact your plan administrator in writing and request a review.

Tax implications of receiving both programs

SSDI payments may be taxable depending on your total income. If you also receive LTD payments, your combined income could push you into a tax bracket where SSDI becomes taxable. This is complex and depends on your filing status, other income sources, and the specific amounts you receive.

LTD payments are generally not taxable if you paid the premiums with after-tax dollars (money from your paycheck after taxes were already taken out). However, if your employer paid the premiums, your LTD payments are taxable as income.

Because the tax treatment varies widely, consult a tax professional or contact the IRS directly before filing your taxes. Social Security will send you a form showing your SSDI income, and your LTD plan will send you a form showing your LTD income. You will need both to file accurately.

Frequently Asked Questions

Can I receive both LTD and SSDI at the same time?

Yes. Both programs can pay you simultaneously. However, if your LTD plan has an offset clause, your LTD payment will be reduced by the amount you receive from SSDI, so your total monthly income may not increase after SSDI approval.

What if my LTD plan denied me but I think I may have access to for SSDI?

An LTD denial does not prevent you from explore for SSDI. The two programs use different standards. You can explore to Social Security independently. However, if your LTD plan approved you, that strengthens your SSDI case because it shows another insurer agreed you cannot work.

Do I have to tell Social Security about my LTD payments?

Yes. When you explore for SSDI, you must report any long-term disability income you receive. Social Security uses this information to verify your income and coordinate benefits. After approval, notify your LTD plan in writing so they can adjust your payment if they have an offset clause.

What happens to my SSDI when my LTD payments end?

Your SSDI continues as long as you remain disabled and do not return to substantial work. At age 65 or 66, your SSDI automatically converts to retirement benefits at the same payment amount. LTD ending does not affect your SSDI status.

Will I owe money back if my LTD plan offset my payment incorrectly?

If you received more money than you were may have access to to because of an offset error, Social Security or your LTD plan may ask you to repay the overpayment. Request a written explanation of any offset calculation and verify the math. If you believe an error occurred, contact your plan administrator in writing and ask for a review.
