TL;DR
Yes, most private long-term disability policies require you to apply for SSDI benefits. The reason is simple: if you win SSDI, your insurer pays you less. That reduction is called an offset clause, and it's standard in group LTD plans. Refusing to apply can let your insurer cut your benefit by the SSDI amount it estimates you would have received.
Why do most LTD policies require applying for SSDI?
The short answer is money. Your LTD insurer has a direct financial stake in whether you get SSDI, because almost every group LTD policy contains a provision that lets the insurer subtract your SSDI payment from the monthly LTD benefit it owes you. That subtraction is called a Social Security offset or coordination-of-benefits clause.
Here is how the math works. Suppose your LTD policy pays 60% of your pre-disability income and that comes to $3,000 a month. You then win SSDI and receive $1,500 a month from Social Security. Your insurer typically reduces its payment to $1,500, so your total stays at $3,000 but the insurer is now only writing you a check for half that amount. The insurer's cost dropped by $1,500 every month. Over a multi-year claim, that is a very large number.
Because of that incentive, LTD insurers don't just encourage you to apply for SSDI. Most group policies make it a contractual obligation. Failing to apply, or abandoning the process before a final SSA decision, gives the insurer grounds to treat your benefit as if you had already been awarded the Social Security amount it estimates you would have received. Insurance professionals call this an "estimated offset" or "phantom offset," and it can reduce your monthly check even though no SSDI money is actually coming in.
Do most private LTD policies require applying for SSDI? The answer is yes for employer-sponsored group plans. The requirement is less universal in individually purchased policies, where the language varies widely by insurer and plan design. If you bought your own policy outside of work, read the coordination-of-benefits section carefully before assuming an obligation exists.
What is an SSDI offset clause and how does it actually work?
An offset clause is contract language that reduces what your LTD insurer pays you by any amount you receive from Social Security Disability Insurance. Most clauses also extend to Social Security dependents' benefits paid on your record, so if your minor child receives an auxiliary SSDI benefit, that amount can come off your LTD check too.
Offset clauses generally come in two forms. A direct offset reduces your monthly LTD payment dollar-for-dollar by your actual SSDI award. An estimated offset (sometimes called a constructive offset) lets the insurer reduce your payment by what it calculates you should receive from SSDI, regardless of whether you applied or won. The estimated offset is the tool that lets the insurer require you to apply in the first place.
Some policies include a minimum benefit floor, often $100 per month, so the offset cannot eliminate your LTD payment entirely. Others do not. Read your Summary Plan Description or individual policy carefully; the offset section is usually labeled "Other Income Benefits" or "Deductible Sources of Income."
One nuance trips people up: lump-sum SSDI back pay. When you win SSDI after a long wait, SSA pays you retroactive benefits going back to your established onset date (up to 12 months before your application) [1]. Most LTD policies require you to repay the insurer for the months it paid you in full before your SSDI award, because during those months you got LTD without any offset applied. That repayment obligation is real and can arrive as a demand letter for tens of thousands of dollars. Budget for it.
What happens if you refuse to apply for SSDI when your LTD policy requires it?
Refusal triggers the estimated offset in nearly every policy that has one. Your insurer calculates what it believes SSA would have paid you, and it starts deducting that figure from your LTD benefit immediately. You end up with a reduced check and no actual SSDI income to make up the difference.
Beyond the financial hit, some policies go further. Repeated non-compliance can give the insurer grounds to terminate your claim entirely, on the theory that you have breached a material term of the contract. Whether that termination would survive a legal challenge depends on the specific policy language and the law of your state. Fighting it is expensive and slow.
Say you have a legitimate reason for not wanting to apply. Maybe you are close to retirement age and the SSDI benefit calculation would be a bad deal, or you have pending immigration considerations. Talk to a disability attorney before you simply ignore the requirement. There are documented situations where claimants negotiated a waiver of the SSDI application requirement with their insurer, but those are exceptions, not the rule.

Does the offset apply to SSI as well as SSDI?
No. SSI (Supplemental Security Income) is a needs-based program, not an earnings-based one, and the great majority of LTD policies specify that the offset applies to Social Security Disability Insurance benefits, not to SSI. If you receive only SSI because you lack the work credits required for SSDI, your LTD insurer typically cannot offset your SSI payment.
That said, read your specific policy. Some older or individually drafted policies use broader language like "any Social Security benefit," which an insurer might argue covers SSI. Courts have generally rejected that reading when the policy language is specific, but it has been litigated.
If you are unclear on the difference between the two programs, SSDI vs SSI: What's the Difference and Which Do You Qualify For? walks through the key distinctions. The short version: SSDI is funded by payroll taxes and requires work credits; SSI is funded by general revenue and is based on financial need. For LTD offset purposes, they are treated very differently.
How long do you have to apply for SSDI after your LTD insurer asks?
Most LTD policies give you a specific window, often 30 to 90 days from the date the insurer sends a written request, to submit an SSDI application. After that deadline, the estimated offset typically kicks in automatically.
The request usually comes early in your claim, sometimes within the first few months of receiving LTD payments. Insurers know that SSDI takes a long time. The Social Security Administration's average processing time for an initial SSDI decision runs roughly three to six months, and that assumes you do not get denied and have to appeal. More than half of initial applications are denied [2]. If you ultimately need a hearing before an Administrative Law Judge, the national average wait has historically run from 12 to 24 months depending on your hearing office backlog [3].
Apply quickly after your insurer requests it. That is almost always the right move, because the date you apply affects your potential back-pay period. SSA pays retroactive benefits going back up to 12 months before your application date (after a five-month waiting period) [1]. The longer you wait to apply, the more back pay you leave on the table and the longer before the estimated offset is replaced by a real, accurate offset based on your actual award.
For a full picture of how the SSDI application works from the SSA side, the SSDI application guide covers the forms, evidence, and timeline.
What does the SSDI application process involve?
Applying for SSDI means submitting an application to the Social Security Administration, either online at ssa.gov, by phone at 1-800-772-1213, or in person at a local SSA field office. The application asks for your medical history, work history, education, and daily functional limitations [4].
SSA then sends your claim to your state's Disability Determination Services (DDS) agency, which reviews your medical records and applies SSA's five-step sequential evaluation process to decide whether you meet the definition of disability. SSA's definition requires that you have a medically determinable impairment expected to last at least 12 months or result in death, and that the impairment prevents you from doing any substantial gainful activity (SGA) [5]. The SGA threshold in 2025 is $1,620 per month for non-blind individuals [6].
For a detailed walkthrough of the eligibility rules, How to Qualify for SSDI: The Complete Eligibility Guide covers the five-step test, the work credit requirements, and what medical evidence SSA actually weighs.
One thing your LTD insurer may do that SSA does not: your insurer might hire a firm to help you apply for SSDI. Some large carriers, including Unum, Lincoln Financial, and MetLife, contract with Social Security advocacy vendors (companies like Allsup or Genex) to guide their claimants through the SSDI process. This is not entirely altruistic. Getting you approved faster means the insurer can start offsetting sooner. You are allowed to decline the insurer's vendor and hire your own representative instead, which is often the wiser choice since a vendor paid by your insurer has a structural conflict of interest.
What is the SSDI five-month waiting period and does it affect your LTD offset?
SSA imposes a five-month waiting period before SSDI benefits begin. Even if your disability onset date is established as January 1, your first SSDI payment covers June (the sixth month) [1]. You cannot receive SSDI for those first five months.
For your LTD offset, most policies offset only the SSDI benefits you actually receive. During the five-month waiting period, you have no SSDI income, so there should be nothing to offset. Watch for policies that define the deductible amount based on when you become entitled to SSDI rather than when you actually receive it. That is less common, but it exists.
The five-month waiting period also matters for back pay calculations. SSA cannot pay you for those five months even retroactively, so the lump sum you eventually receive will not cover them. When your insurer calculates how much of your prior LTD payments to recoup, a well-written policy should exclude those five months from the reimbursement calculation. If yours does not, that is worth challenging with an attorney's help.
For more on the timing rules around disability benefit eligibility, social security disability 5-year rule explains the related five-year rule that applies if you previously received SSDI and want to reopen a claim.
How does the SSDI back-pay repayment to your insurer actually work?
When you win SSDI after months or years on LTD, SSA pays you a lump sum covering the months from your established onset date (minus the five-month waiting period and minus any months more than 12 before your application date). That lump sum can easily be $20,000 to $60,000 or more for a long claim.
Your LTD insurer will send you a reimbursement demand. The insurer's logic: during the period covered by your SSDI back pay, it paid you the full LTD amount without any offset. Now that you have the SSDI money for those months, the insurer wants back the portion it overpaid relative to what it would have paid under the offset clause.
Example: if your monthly LTD benefit was $3,000 and your monthly SSDI award is $1,500, the insurer paid you $1,500 more per month than it was contractually required to pay (once the offset is applied). If you receive 18 months of SSDI back pay, the insurer can demand $27,000.
Many people sign away their entire SSDI lump sum to their LTD insurer and are left with little or nothing. There are protections worth knowing. SSA's fee agreement rules mean your SSDI attorney's fee (up to 25% of back pay, capped at $7,200 in 2024) comes out before the insurer's recoupment, not after [7]. Some courts have also held that the insurer cannot collect more than the actual SSDI back pay received, and certain policy language creates additional limits. An SSDI attorney or disability benefits attorney who understands both sides of this transaction is worth consulting before you sign anything the insurer sends you.

Can you negotiate the SSDI offset or the repayment demand?
Sometimes, yes. Negotiating the offset itself is rare, because it is written into the policy contract. There is more room to move on the back-pay recoupment demand than most claimants realize.
On recoupment, the insurer is generally entitled to what the policy says it is entitled to. But the insurer also does not want to spend money litigating a reimbursement. If you have legal arguments that the insurer's calculation is wrong (wrong onset date, wrong monthly SSDI figure, failure to exclude the five-month waiting period, failure to account for attorney fees paid), you have a real bargaining position.
Some claimants also negotiate a lump-sum settlement of their entire LTD claim, sometimes called a "buyout," at the same time as the SSDI back-pay repayment is being resolved. In a buyout, the insurer pays you a one-time lump sum in exchange for releasing all future LTD claims. Whether a buyout is good for you depends on your age, your health trajectory, how much future LTD benefit you would have received, and tax considerations. Buyouts are not inherently bad or good. Get independent advice before signing one.
If you do pursue a buyout, understand that SSDI and LTD are separate. Settling your LTD claim does not affect your SSDI benefit. SSA does not care about your private insurance settlement. But LTD insurers sometimes try to condition a buyout on you withdrawing or not continuing your SSDI appeal, which could hurt you. Do not agree to that without legal advice.
Are there LTD policies that do not require applying for SSDI?
Yes, though they are the minority. Individually purchased (non-group) disability policies, particularly "own-occupation" policies sold to physicians and other professionals, often contain no Social Security offset clause at all. No offset clause means no incentive for the insurer to require you to apply for SSDI, and most such policies do not.
Even among group plans, a small number of high-end executive benefit plans or carve-out policies are built without Social Security offsets as a feature to attract talent. Some government and union plans also have different structures.
The only way to know what your policy requires is to read it. Ask your employer's HR department for the Summary Plan Description (SPD) and the actual group insurance certificate. For individually purchased policies, your declarations page and policy form are the controlling documents. Look for the section titled "Other Income Benefits," "Deductible Sources of Income," "Reductions," or "Coordination of Benefits."
If you cannot locate your policy documents and your claim is active, your insurer must provide them. Under ERISA (the Employee Retirement Income Security Act, 29 U.S.C. § 1024), which governs most employer-sponsored benefit plans, you have the right to request plan documents and the insurer must produce them within 30 days [8].
How does applying for SSDI affect your LTD insurer's review of your claim?
Here is something most claimants do not expect: an SSDI approval can cut both ways with your LTD insurer. On one hand, if SSA finds you disabled, that is independent expert corroboration of your condition. It can make it harder for the insurer to later deny or terminate your LTD claim on the ground that you are not disabled.
On the other hand, LTD insurers are not bound by SSA's disability determination. ERISA-governed group plans use their own definition of disability and their own review process. An insurer can deny or terminate your LTD claim even after you win SSDI. The U.S. Supreme Court addressed the weight of SSA decisions in the context of ERISA plan reviews in Metro. Life Ins. Co. v. Glenn, 554 U.S. 105 (2008), holding that a prior SSDI award is a relevant factor, but insurers under certain plan structures retain discretion to reach different conclusions [9].
The SSA's own definition of disability differs from many LTD policy definitions. SSA uses a strict "any occupation" standard: can you do any job that exists in significant numbers in the national economy? Many LTD policies use an "own occupation" standard for the first 24 months, then shift to "any occupation." If your policy is still in the own-occupation phase, you might qualify for LTD but not yet for SSDI, or vice versa depending on the facts.
For readers trying to understand the SSDI definition in depth, What Counts as a Disability? The SSA's Definition Explained covers SSA's five-step process and the medical evidence standards.
Should you hire an SSDI attorney separate from your LTD attorney?
Often yes, and the two representatives should at minimum know about each other. The SSDI process and the LTD process are legally distinct. SSDI is governed by the Social Security Act and SSA regulations. LTD claims (when employer-sponsored) are governed by ERISA. Those are different bodies of law, different courts if litigation happens, and different strategic considerations.
An SSDI attorney works on contingency: they collect 25% of your back pay, capped at $7,200 in 2024, paid directly by SSA from your back-pay lump sum [7]. You pay nothing unless you win. That makes hiring one essentially risk-free. An LTD attorney (or the SSDI vendor your insurer sends) is a different matter, and fee arrangements vary.
The conflict of interest with the insurer's vendor bears repeating. If an advocacy company is paid by your LTD insurer to help you get SSDI, its financial alignment is with the insurer. It wants you to win SSDI quickly so the insurer can start offsetting. That objective may or may not match your goal of maximizing your total income across both benefit streams. Your own attorney represents only you.
DisabilityFiled's guided intake tool can help you organize your medical history, work history, and functional limitations into a structured summary before you meet with any representative. Having that information ready makes both your SSDI application and your LTD claim review go faster.

Key numbers every LTD claimant applying for SSDI should know
A few concrete figures put the financial stakes in context.
The average monthly SSDI benefit in 2025 is approximately $1,580 [6]. At that figure, a standard LTD offset saves your insurer roughly $18,960 per year on your claim alone.
The SGA threshold for 2025 is $1,620 per month for non-blind individuals [6]. Earning above that amount while claiming SSDI generally disqualifies you.
SSA's attorney fee cap for SSDI representation is $7,200 (as of November 2024) or 25% of your back pay, whichever is less [7].
The maximum retroactive SSDI benefit period is 12 months before your application date, minus the five-month waiting period, so effectively 7 months of retroactive pay at most [1].
Under ERISA, your insurer must provide plan documents within 30 days of your written request, or face a penalty of up to $110 per day [8].

Frequently asked questions
Do all long-term disability policies require applying for SSDI?
No, but most group (employer-sponsored) LTD policies do. They require it because of offset clauses that let them reduce your LTD payment by your SSDI award. Individually purchased own-occupation policies, especially those sold to professionals, often have no Social Security offset and therefore no application requirement. Check your policy's 'Deductible Sources of Income' or 'Reductions' section to be sure.
What happens if I apply for SSDI and get denied?
If you apply and SSA denies you, most LTD policies require you to appeal through at least the Reconsideration and Administrative Law Judge stages. Some require you to exhaust all administrative appeals before the insurer will waive the estimated offset. Check your specific policy. If you win on appeal, your back pay period extends back to your original application date, which matters both for SSDI income and for calculating what you owe the insurer.
Can my LTD insurer reduce my check before I actually receive any SSDI money?
Yes. This is the estimated offset. If your policy allows it, the insurer calculates what it thinks SSA would pay you and starts deducting that amount from your LTD check, even before you have applied or won. The insurer typically adjusts the offset (up or down) once an actual SSDI award is made. Until then, you may receive less than your full LTD benefit with no SSDI income to fill the gap.
Does winning SSDI guarantee my LTD claim stays approved?
No. LTD insurers are not bound by SSA's disability determination. Under the ERISA framework governing most group plans, your insurer uses its own definition of disability and its own review process. The Supreme Court held in Metro. Life Ins. Co. v. Glenn (2008) that an SSDI award is a relevant factor but not binding. Your insurer can still terminate your LTD claim independently.
How much SSDI back pay will my LTD insurer demand back?
It depends on your monthly SSDI award and how many months the insurer paid you without applying the offset. The formula is generally: (monthly SSDI amount) x (number of overlapping months). On a $1,500 monthly SSDI award with 24 months of overlap, the demand could be $36,000. Your SSDI attorney's fee is subtracted first. Some policy language and state court decisions also limit how much the insurer can recoup.
Can I use my SSDI approval to fight an LTD denial or termination?
You can raise it as evidence and courts have considered it relevant, but it is not a slam dunk. Under ERISA, if your plan gives the insurer discretionary authority to interpret plan terms, courts apply a deferential 'abuse of discretion' standard rather than reviewing the decision from scratch. An SSDI approval strengthens your case but does not automatically reverse an LTD denial.
Does my LTD insurer offset my children's SSDI auxiliary benefits too?
Most policies say yes. When you are approved for SSDI, your minor children may receive auxiliary benefits on your record, typically 50% of your SSDI amount per child, up to a family maximum. Standard LTD offset clauses include these dependent benefits as 'deductible income.' Some policies exclude them, so read your specific language carefully.
What if I am close to Social Security retirement age and applying for SSDI seems pointless?
SSDI converts to retirement benefits at full retirement age automatically, so there may still be value in applying even close to retirement. However, your insurer's requirement to apply may be practically waivable if the economics don't work out. Talk to an attorney. Some insurers agree in writing to waive the SSDI application requirement for claimants within 12 to 24 months of full retirement age, but you must request that waiver.
Is the SSDI offset taxable differently than the LTD benefit?
SSDI and LTD are taxed differently. Employer-sponsored LTD benefits are generally taxable as ordinary income if your employer paid the premiums. SSDI is taxable only if your combined income exceeds $25,000 (single) or $32,000 (married filing jointly). The offset itself is not separately taxable; it just determines how much of each type of benefit you receive. For a full breakdown, see is SSDI taxable on this site.
Can I decline the SSDI application vendor my LTD insurer sends me?
Yes. You have no obligation to use the insurer's preferred vendor. You can hire your own SSDI attorney or representative. Given that the insurer's vendor is paid by the insurer, its interests may not fully align with yours. Your own attorney represents only you and is paid on contingency from your SSDI back pay, so the cost to you is the same either way.
Does applying for SSDI affect my LTD claim timeline?
Indirectly. SSDI decisions can take 12 to 24 months or more if you appeal to the ALJ level. During that time your LTD claim continues under its own review cycle. If SSA approves you, the insurer then adjusts the offset and potentially sends a recoupment demand. Applying early shortens the total window and maximizes potential back pay, which benefits both you and (via offset recovery) your insurer.
What SSDI work credit requirements do I need to meet before I can even apply?
Most workers need 40 credits total, with 20 earned in the last 10 years before disability. Younger workers need fewer. In 2025, you earn one credit for each $1,810 in earnings, up to four credits per year. If you lack sufficient credits, you do not qualify for SSDI at all, only potentially for SSI. Your LTD insurer's offset clause may be moot if you are ineligible. For a full explanation, see the SSDI work credits guide on this site.
If I settle my LTD claim in a lump sum, does that eliminate my obligation to continue with SSDI?
No. SSDI is a federal program independent of your private insurance. Settling your LTD claim does not affect your SSA application or award. However, some insurers try to condition a buyout on you abandoning SSDI appeals. Do not agree to that without legal advice. Continuing your SSDI claim after an LTD settlement is generally both permitted and financially worthwhile.
How do I find out if my specific LTD policy has a Social Security offset clause?
Request your Summary Plan Description and group insurance certificate from your HR department or directly from your insurer. Under ERISA, the insurer must provide these within 30 days of a written request. Search for sections titled 'Deductible Sources of Income,' 'Other Income Benefits,' 'Reductions,' or 'Coordination of Benefits.' If the clause exists, it will specify which Social Security benefits count and how the offset is calculated.
