SSDI and Workers' Compensation Offset in 2026

By Anthony Albert, Benefits Research Director at Disability Exchange · Published 2026-08-08 · 13-minute read

If you're getting workers' compensation and you also qualify for SSDI, the two benefits don't stack cleanly. Federal law caps your combined public disability income at 80% of what you were earning before you got hurt. Anything over that cap comes out of your SSDI check. This is the workers' comp offset, and it can cut your SSDI in half or more if you don't structure things carefully.

This article breaks down how the 80% cap works, which states flip the offset onto workers' comp instead, how to write lump-sum settlement language that limits the SSDI hit, and the carveouts that most people miss.

Where the offset comes from

Section 224 of the Social Security Act (42 U.S.C. 424a) says that if you receive both SSDI and workers' compensation or a public disability benefit (PDB), your combined monthly payment cannot exceed 80% of your Average Current Earnings (ACE). If the combined benefits exceed 80% of ACE, SSA reduces your SSDI to bring the total back down to the 80% line.

The regulation implementing this is 20 CFR 404.408. The offset applies until you reach full retirement age (67 for anyone born in 1960 or later). At FRA, SSDI converts to retirement benefits and the offset stops.

What counts as workers' compensation for offset purposes

Workers' comp offset covers:

Public Disability Benefits (PDB) that also trigger offset

Under 20 CFR 404.408(a)(2), the offset also applies to state and local government disability benefits that are not based on Social Security taxes. These are called Public Disability Benefits (PDB). Common examples:

Important: If you were covered by Social Security while earning the pension, PDB offset does NOT apply. This is why teachers in some states (California, Ohio, Texas) get hit hard while teachers in states with dual coverage don't.

What does NOT count for offset

How Average Current Earnings (ACE) is calculated

ACE is the higher of three formulas under 20 CFR 404.408(c):

  1. Highest Year of Earnings method: The highest year of earnings in the 5 years before the year of disability onset. Divided by 12 for the monthly ACE.
  2. Average Monthly Wage method: The same average monthly wage SSA uses to compute your PIA (Primary Insurance Amount).
  3. High Five method: The average of your 5 highest consecutive years of earnings out of any period. Divided by 12.

SSA picks whichever method gives you the highest ACE. That's the number to base the 80% cap on. This works in your favor.

Worked example

You got hurt at work in June 2024. Your onset date is June 1, 2024. Your earnings for the 5 years before disability:

Highest year: $76,500 / 12 = $6,375/month ACE (method 1).

80% of ACE: $6,375 x 0.80 = $5,100/month.

If your SSDI is $2,400/month and your workers' comp is $3,200/month, combined = $5,600. That's $500 over the cap. SSA offsets $500/month from SSDI. Your SSDI drops to $1,900/month.

Total combined income: $1,900 SSDI + $3,200 WC = $5,100 (right at the 80% cap).

Reverse offset states

Fifteen states run the offset in reverse. Instead of SSDI being reduced, the state's workers' comp benefit is reduced by the SSDI amount. Under 42 U.S.C. 424a(d), reverse offset applies in states whose laws had a WC/SSDI coordination rule in place by February 18, 1981.

Reverse offset states:

In reverse offset states, your SSDI comes through at the full amount. Your workers' comp benefit gets reduced instead. Practical outcome: same total income (still capped at 80% of ACE), but the reduction hits a different source. Reverse offset states are often better for claimants because SSDI cannot be reduced below the auxiliary family maximum.

See state pages for local rules: California, New York, Ohio, Washington, Wisconsin.

Lump-sum workers' comp settlements

Most workers' comp cases end in a lump-sum settlement, not ongoing monthly payments. When this happens, SSA has to allocate the lump sum over time to figure out the monthly offset. Under 20 CFR 404.408(g), SSA looks at the settlement agreement language first.

The three settlement scenarios

Scenario A: Silent settlement. The settlement agreement doesn't specify how the money is allocated. SSA divides the entire lump sum by the workers' comp state's maximum weekly rate to compute a monthly equivalent. This usually creates a large monthly offset that runs for years.

Scenario B: Prorated by expected duration. The settlement agreement says the lump sum represents payments at $X/week for Y years. SSA generally accepts this allocation. Lower monthly offset. Shorter offset period.

Scenario C: Life expectancy proration. The settlement agreement says the lump sum represents payments over the claimant's life expectancy. SSA uses actuarial tables to compute the monthly equivalent. Usually creates the smallest monthly offset. This is often the best language to use.

Sample proration language that works

"The parties agree that this lump-sum settlement of $150,000 represents commutation of benefits at the rate of $250 per week for a period of 600 weeks, commencing on [date]. This allocation reflects the claimant's remaining work life expectancy per the [state] mortality tables."

This language forces SSA to divide $150,000 by 600 weeks, giving $250/week or about $1,083/month. If ACE-based cap is $5,100, and SSDI is $2,400, and WC allocation is $1,083, the total is $3,483. Under the cap. No offset.

Attorney fee carveout

Under SSA policy (POMS DI 52150.050), the portion of a workers' comp settlement used to pay attorney fees is NOT included in the offset calculation. Same for medical expenses paid to providers as part of the settlement.

Example: $150,000 total settlement. $30,000 to attorney (20%). $10,000 to unpaid medical bills. The offset amount is $150,000 - $30,000 - $10,000 = $110,000. Then prorate over the expected weeks. This reduces monthly offset materially.

Push your workers' comp attorney to itemize:

Medicare Set-Aside (MSA) considerations

If you're on Medicare (or approaching Medicare eligibility) and settling a workers' comp claim, you probably need a Medicare Set-Aside (MSA). The MSA funds future medical care that would otherwise fall on Medicare. Under CMS policy, MSA amounts are excluded from the workers' comp offset if properly documented.

MSA rules apply when you're already on Medicare and the settlement exceeds $25,000, or you're within 30 months of Medicare eligibility and the settlement exceeds $250,000.

How the offset changes at age 62 and full retirement age

At age 62, some workers' comp benefits terminate under state law. SSDI stays. Once WC ends, no more offset. Your SSDI check goes back up to its pre-offset amount.

At full retirement age (67 for anyone born in 1960 or later), SSDI automatically converts to Social Security retirement benefits. The workers' comp offset ends completely. This is written into the statute. See 42 U.S.C. 424a(a).

What happens when you also have LTD insurance

Private LTD (Long-Term Disability) insurance doesn't trigger federal offset. But LTD policies typically have their own SSDI offset clauses in the contract. The LTD carrier reduces its payment by the amount of your SSDI. Read the LTD policy for details.

Common LTD offset patterns:

If you have SSDI, WC, and LTD, the interaction gets complex. LTD reduces first based on the SSDI offset amount. Then WC offsets SSDI. Then FRA lifts the WC offset. Talk to a rep who understands all three systems.

How SSA calculates and applies the offset

The mechanics:

  1. Determine your monthly SSDI benefit (before offset).
  2. Determine your monthly workers' comp or PDB (or the prorated monthly value of a lump-sum settlement).
  3. Add them together.
  4. Compare to 80% of ACE.
  5. If combined benefits exceed 80% of ACE, SSA reduces SSDI by the excess.
  6. The offset cannot reduce SSDI below your family maximum benefit (auxiliary benefits still get paid).

Recalculation triggers:

ACE inflation adjustment

Under 20 CFR 404.408(f), SSA can redetermine ACE every 3 years if the general wage level has increased. This typically raises the 80% cap and reduces the offset. Not automatic. You may need to request the redetermination if SSA doesn't do it on its own.

Common workers' comp offset mistakes

  1. Silent settlement language. The biggest and most expensive mistake. Force explicit proration.
  2. Not itemizing attorney fees, medical expenses, and MSA. This inflates the offset base unnecessarily.
  3. Prorating over too few weeks. Life expectancy proration is often better than a short-term proration.
  4. Not reporting SSDI to the WC carrier in reverse offset states. The carrier may not know about SSDI unless you tell them, and they miss reducing WC. But when SSA finds out, you owe.
  5. Ignoring the ACE redetermination. Every 3 years, request an ACE update.
  6. Forgetting to notify SSA when WC ends. You lose out on months of full SSDI payment while SSA still thinks the offset applies.

Filing sequence when both claims are pending

General rule: File SSDI first, or at least concurrently. Delayed SSDI filings after WC settlement can lock in a bad offset structure. SSA will look at whatever WC was in place at the SSDI onset date.

See our PFD article for how to lock in an early SSDI filing date.

The 5-year auxiliary offset rule for children on the record

The WC offset applies to your primary SSDI benefit but generally doesn't cut into auxiliary benefits paid to your children or spouse below the family maximum. Under 20 CFR 404.408(b), the offset amount is calculated on total family benefits, but the reduction is applied only to the wage earner's SSDI. Auxiliary payments continue.

Example: You get $2,400 SSDI. Your two minor children get $600 each in auxiliary benefits ($1,200 total family aux). Family maximum is $3,600. Combined SSDI + aux = $3,600. Workers' comp is $2,400. Combined SSDI + WC = $4,800. If 80% ACE cap is $4,200, the offset is $600. That $600 comes off your SSDI, dropping it to $1,800. Children's benefits stay at $600 each. Family total drops from $6,000 to $5,400.

Special rule for Black Lung and FECA

Federal Black Lung benefits under 30 U.S.C. 921 have their own offset framework. Coordination with SSDI happens under a separate statutory scheme. If you're on Black Lung Part B, no SSDI offset. If you're on Black Lung Part C, offset math is different and typically less severe than state WC offset.

FECA benefits for federal employees follow the general workers' comp offset rules. But FECA lump sums are usually structured with clear proration language because federal counsel understands the offset math. This is one context where lump-sum settlements often produce optimal outcomes without special drafting.

Reporting requirements

You must report to SSA within 30 days if:

Failure to report can create overpayments. Overpayments must be repaid. Under 20 CFR 404.502, SSA can recover overpayments by withholding future benefits, filing federal tax refund offsets, or civil recovery actions.

The special SGA rule for statutorily blind claimants

Statutorily blind SSDI recipients have a higher SGA threshold ($2,830/month in 2026 vs $1,690 for non-blind). Blind SSDI recipients over age 55 who take work that doesn't use their prior skills can pause TWP counting under special rules. This doesn't affect WC offset directly but changes how work interacts with SSDI eligibility.

Related: closed period and offset

If you file a closed period SSDI claim after returning to work, and you also received workers' comp during the closed period, offset math still applies for the closed period. See our closed period article.

Coordinating with SSI

If you're on concurrent SSDI/SSI, workers' comp affects both. WC counts as unearned income for SSI (after the $20 general exclusion). SSI is reduced dollar-for-dollar by the WC amount above $20. SSI can zero out entirely if WC is large enough. Meanwhile, SSDI is reduced by the standard 80% ACE offset. Double whammy.

See our SSI income exclusions article for the SSI side of the math.

FAQ

What is the SSDI workers' comp offset?

Under Section 224 of the Social Security Act, if you receive both SSDI and workers' compensation, your combined benefits are capped at 80% of your Average Current Earnings. SSDI is reduced to keep you under that cap.

What is Average Current Earnings?

ACE is the higher of three formulas: highest year of earnings in the 5 years before onset, your average monthly wage used for PIA, or the average of your 5 highest consecutive years. SSA picks the highest result.

Which states use reverse offset?

Fifteen states: Alaska, California, Colorado, Florida (limited), Louisiana, Minnesota, Montana, Nevada, New Jersey, New York, North Dakota, Ohio, Oregon, Washington, Wisconsin. In these states, workers' comp is reduced instead of SSDI.

Does VA disability compensation trigger the offset?

No. VA disability, private LTD, private STD, SSI, and third-party tort settlements do not trigger federal offset.

How do I prorate a lump-sum workers' comp settlement?

Write settlement language that specifies weekly rate and number of weeks, or life expectancy. Life expectancy proration usually creates the smallest monthly offset.

Are attorney fees excluded from the offset?

Yes. Under SSA policy (POMS DI 52150.050), attorney fees, medical expenses paid to providers, and Medicare Set-Aside amounts are excluded from the offset base.

When does the offset end?

The offset ends when workers' comp ends, or automatically at full retirement age (67 for anyone born in 1960 or later) when SSDI converts to retirement benefits.
