If you get both long-term disability (LTD) benefits and Social Security Disability Insurance (SSDI), you may be concerned about how the payments affect each other, especially when you get back pay.
This article explains how an LTD SSDI offset works, why SSDI back pay can create an LTD overpayment, and what to do if you receive a repayment notice. It also includes timelines, examples, and practical next steps. It also includes timelines, examples, and practical next steps.
Read on to learn about LTD with SSDI.
When you have LTD and are approved for SSDI, a long-term disability offset usually affects your LTD payments, not your SSDI. That’s because many LTD policies include an SSDI offset, which allows the insurer to reduce LTD payments after SSDI begins.
Once SSDI begins, the insurer adjusts your monthly LTD payment based on the SSDI amount. When you get SSDI back pay, you may have an LTD overpayment for the months you were eligible for both.
If you get an overpayment letter, it means your disability insurer updated your claim after SSDI approval and is applying the policy rules, not that you did anything wrong.
Overpayments are common because SSDI claims take months to process, so most cases include back pay.
Before we discuss these programs more, these are key terms you need to know.
An SSDI offset means your LTD benefit may be reduced by your SSDI amount.
For example, if your LTD benefit is $2,500 per month and your SSDI is $1,200 per month, your LTD payment may drop to $1,300 after the offset is applied.
SSDI back pay is money the SSA pays for past months after your claim is approved. You can be eligible for SSDI for up to 12 months before the month you applied if the SSA finds you were disabled during that time.
When the SSA pays for overlapping months your insurer is already covered with LTD, the insurer may treat that overlap as an LTD overpayment and ask for repayment.
This part can be the most confusing. Private LTD usually does not reduce SSDI. Instead, LTD policies often pay less after SSDI approval.
The SSA has separate offset rules for some public benefits, but those are different from private LTD offsets. In most cases, LTD changes and SSDI does not.
The long-term disability offset usually applies to the months SSDI is payable for, not just the date you were approved
That distinction matters because the SSA may approve your claim today and pay you for earlier months. The insurer looks at those earlier months when applying the offset.
Some insurers estimate the SSDI amount while your claim is pending and reduce LTD early. If that happens, ask what estimate they used and how it will be updated.
It helps to think in months, not in approval letters. The SSA can approve your claim and then pay for earlier months. The insurer compares those payable months to the months it paid LTD. When those months overlap, it creates an overpayment.

Get EvaluationMost overpayments come from overlapping payments because it takes five to eight months for the SSA to process a disability application, without appeal steps.
Most LTD policies state that payments are reduced by SSDI benefits. Since you weren’t approved yet, that offset was unknown. Once you are approved, the insurer adjusts those past payments and claims the difference.
Overlap simply means the same months were paid twice. LTD paid first. SSDI paid later for those same months. The insurer then applies the offset to those months and calculates what should have been paid instead.
This is why a month-by-month breakdown is so important. It lets you see exactly where the overlap occurred and how the offset calculation was made.
Assume LTD pays $2,500 per month for six months, for a total of $15,000. Later, SSDI is approved for those same six months at $1,200 per month, resulting in $7,200 in back pay.
If the policy applies a dollar-for-dollar offset, the insurer may claim about $7,200 as an overpayment because LTD should have been reduced during those months.
Assume LTD pays $2,000 per month for 10 months. SSDI is later approved for eight of those months at $900 per month. That results in $7,200 SSDI back pay.
The insurer may claim an overpayment for those eight overlapping months. Going forward, your LTD benefits most likely drop to reflect the SSDI amount, but your total monthly income may stay similar.
Most LTD policies require repayment after SSDI back pay. This is usually outlined in the policy or in a reimbursement agreement you signed. This isn’t a penalty. It’s just how the policy applies the SSDI offset.
Insurers typically recover overpayments in one of three ways:
If you choose a repayment plan, ask for the terms in writing and keep records of each payment.
Before you agree to repay, review the calculation carefully. Ask for a written, month-by-month breakdown. Then compare it to your SSDI award details.
You should confirm that the overlapping months match, that the SSDI amount is correct, and that any prior offsets or credits were applied. If dependents are involved, check how those benefits were handled.
Keep copies of all communication. If something looks off, respond in writing and ask for a corrected calculation.
Gather these documents before you contact your disability insurer about your SSDI approval or an overpayment notice. The insurer will use them to calculate the offset and any repayment amount.
You will likely need:
Send these to your LTD insurer when you report your SSDI approval or when you respond to an overpayment notice. This helps the insurer complete or correct its calculation.
When sending documents, label them clearly, include your claim number, and track when you sent them.
When you contact your insurer, be clear and direct. State that your SSDI claim was approved, include your approval date, monthly benefit, and back pay period, and request a month-by-month calculation.
Ask them to confirm the overlap months and the SSDI amount used in the offset calculation before you agree to repayment.
Not all LTD policies handle offsets the same way. Some apply a dependent benefits offset, while others do not. Some use estimated SSDI amounts before approval. Others include minimum benefit amounts that limit how much LTD can be reduced.
The policy language controls how your claim is handled, so ask the insurer to point out the exact section used in the calculation.
If you are waiting on SSDI, stay organized and keep track of your LTD payments and key dates. Ask your insurer how it handles offsets and what documents it will need after approval.
If you are approved with SSDI back pay, gather your documents, notify the insurer, request the calculation, and verify the numbers before choosing a repayment option. Keep a clear record of everything.
