SSSDI vs. Long Term Disability Insurance

When comparing SSDI vs. long term disability, Social Security Disability Insurance (SSDI) and long-term disability insurance (LTD) both provide monthly income when you can’t work, but they’re distinctly different programs through different providers. 

This article explains SSDI vs long term disability, including the differences, when you might get both, and how offsets work when benefits overlap. It also provides a checklist of important sections to review in your LTD policy.

SSDI vs. Long Term Disability: Key Differences 

SSDI is a federal disability benefit through the Social Security Administration (SSA). The Social Security taxes you paid on your earnings fund your SSA retirement and SSDI if you are unable to work because of a medical condition. You must meet strict SSA disability rules and have enough work credits from taxes to qualify for SSDI.

LTD insurance is private disability insurance that you or your employer buys. It pays a portion of your wage when you can’t work because you’re hurt or sick. LTD insurance policies vary in how they define a disability, how much they pay, and how long they pay. Policies are either paid when a disabling condition keeps you from doing your “own occupation” or when you can’t do “any occupation.”

Category SSDI Long-Term Disability
Type Federal benefit Private insurance
Who manages Social Security Administration Insurance company
Based on Work history and SSA rule Policy terms
Disability standard Federal disability rules “Own occupation” or “any occupation” policy type
Benefit amount Based on earnings record Usually 50% to 70% of prior income

Can You Receive SSDI and LTD at the Same Time?

You can get both SSDI and LTD at the same time. Typically, you get LTD first and then apply for SSDI. Most policies require that you apply for SSDI if your condition is expected to last at least 12 months or result in death (a basic SSDI requirement).

Getting approved for SSDI can take months, a year, or longer. If you get approved, you get back pay for the months between your application date and approval date. You may also get up to 12 months of retroactive benefits if the SSA finds that you met disability rules in those months. That leads to a lump sum of back pay.

While you can get SSDI and LTD at the same time, most LTD policies include an LTD offset for SSDI, meaning the insurer pays you less.

Why LTD Insurers Require You to Apply for SSDI

LTD companies require you to apply for SSDI to reduce their financial burden. If you get approved for SSDI, the insurer typically applies an LTD offset and reduces your LTD payment amount by your SSDI amount. 

Some insurers refer claimants to a disability representative to help you apply. Ask how that service works, what they do, and if there is a fee. 

You’re also allowed to get your own disability representative. See what a representative can do for you. Keep a copy of your insurer’s letters and representative agreement if you sign one.

How SSDI Offsets Reduce LTD Benefits

With an offset, your monthly income from SSDI and long term disability benefits may not change; it will just come from both programs. 

Example: How SSDI Changes an LTD Payment 

Before SSDI starts:

Benefit Source Monthly Amount
LTD $3,000
SSDI $0
Total $3,000

‍

After SSDI starts:

Benefit Source Monthly Amount
LTD $1,600
SSDI $1,400
Total $3,000

‍

In this example, when SSDI pays $1,400 per month, the LTD insurer reduces its payment by the SSDI payment amount. The total remains $3,000, but the insurer pays less each month. Your exact SSDI amount and long term disability benefits depend on your LTD policy and SSDI award. 

How LTD Offsets Affect Your SSDI Back Pay

Most SSDI awards come with back pay because it takes so long to get approved and you may have retroactive benefits. If you got LTD benefits for those same months, the insurer would say it overpaid you and ask for reimbursement of benefits from overlapping months.

Example: LTD paid $3,000 per month for 10 months. SSDI later awards $1,400 per month for those same 10 months. The insurer can claim a $14,000 overpayment and ask for SSDI back pay reimbursement from the lump sum. 

Some policies also count dependent SSDI benefits when calculating an offset. That means the dependent’s benefit amount will also be deducted.

Ask the insurer for the SSDI back pay reimbursement calculation in writing before agreeing that the number is right. Review the dates of coverage and monthly benefits for both SSDI and LTD. If you’ve had LTD and get approved for SSDI, don’t spend the back pay until you get the offset calculation. Save copies of all notices and letters on awards and offsets.

What to Check in Your LTD Policy

To see how SSDI affects your LTD insurance benefit, read your policy closely. Look for terms about other income, repayment, and claim cooperation.

Policy terms to look for:

  • Social Security disability
  • Other income benefits
  • Offset
  • Reimbursement
  • Overpayment
  • Estimated benefits
  • Dependent benefits
  • Required cooperation
  • Own occupation
  • Any occupation

If you have employer-provided LTD, ask your human resources department or plan administrator for the full policy or plan summary. A benefits portal or short brochure might leave out details about offsets and repayment.

What to Do When Your LTD Insurer Tells You to Apply For SSDI

When you get a letter from the LTD insurer stating you must file for SSDI, don’t stress. Mark the deadline for applying on your calendar.

Your letter should explain possible offsets, but you may want to contact your insurer and get specifics. Use these questions to guide the conversation:

  • Where does the SSDI requirement appear in my LTD policy?
  • Will SSDI reduce my LTD payment?
  • How will SSDI back pay reimbursement be calculated?
  • Are dependent SSDI benefits included in my policy offsets?
  • Do you provide help with the SSDI application?

Take notes and record the date and the name of the person you talk to.

If you’re ready, this guide will help you apply online. You can also file in person at your local SSA office or call the SSA at 1-800-772-1213.

FAQs About SSDI and Long-Term Disability

Can I collect SSDI and LTD at the same time?

Yes, you can receive both SSDI and LTD, but usually the LTD insurer will reduce the amount it pays when you get SSDI.

Will SSDI reduce my LTD check?

Probably. Most LTD policies have an offset clause that reduces your LTD benefit by the amount of the SSDI benefit.

Can my LTD insurer take my SSDI back pay?

Your insurer can require a reimbursement from your SSDI back pay if your LTD insurance has an offset policy. Ask for the repayment calculation in writing.

Why does my LTD insurer want me to apply for SSDI?

LTD policies require that you apply for SSDI to reduce the insurer’s monthly payment. Your combined monthly benefit amount is usually the same as your previous LTD payment.

Does LTD approval mean I will be approved for SSDI?

No. LTD insurance policies and SSDI use different rules. Learn about the SSA’s disability rules.
