SSDI and workers' compensation (the offset)

Getting hurt at work sets off two systems at once. Your state's workers' compensation starts replacing part of your wage, and if the injury keeps you from working long-term, SSDI — Social Security Disability Insurance, the benefit you earned by paying into Social Security (L56) — can start too. And right at the moment you finally have two checks coming, somebody at physical therapy or in a Facebook group says the frightening thing: *they'll take one away. You can't have both. And if you signed a settlement — oh, you've really done it now.* If that's the dread you walked in with, set it down. Nobody loses both checks. The real rule is a cap, not a cancellation: SSDI is trimmed only so that workers' comp and SSDI together don't exceed 80% of your old average earnings — and the combined total is never allowed to fall below what your SSDI alone would have been.

But the second half of the whisper has a true core, and this lesson takes it seriously: a lump-sum settlement of your workers'-comp case is prorated into a monthly amount using the settlement's own wording, and a well-drafted paragraph versus a silent one can swing your SSDI by hundreds of dollars a month for years. That's not a reason to panic — it's a reason to have a workers'-comp lawyer draft the settlement, and we'll show you exactly why, in dollars, on a real picker from a real warehouse floor. All figures in this lesson use the 2026 rules.

Marisol Ortega is 47, from Allentown, Pennsylvania, in the Lehigh Valley — a stretch of I-78 so dense with fulfillment centers that half her neighborhood works in one. For eleven years she was an order picker: scanner on her hip, twelve miles of concrete a shift, totes coming down the line. In March 2025, a mis-stacked pallet came down instead, and the crush injury to her lower spine ended the work she knew. Two surgeries later she can walk her dog around the block, slowly. She cannot lift, twist, or stand a shift, and her medical team doesn't expect that to change.

Because the injury happened on the job, Pennsylvania's workers' compensation system began paying her a wage-loss benefit. And because the disability is total and long-term, she applied for SSDI and was approved on her strong work record. So Marisol now sits exactly where this lesson's fear lives: two checks, one federal and one state, and a letter from Social Security with the word "offset" in it. She is not doing anything wrong by receiving both — the two programs are *designed* to coexist. The rest of this lesson is the math of how.

Here is the whole rule, plainly. When you receive both SSDI and workers' compensation, Social Security adds them together and compares the total to a ceiling — the applicable limit. If the combined total is over the ceiling, SSDI is reduced by the excess — just enough to bring the total down to the ceiling, and no further. The ceiling is 80% of your "average current earnings" — roughly, most of what you were earning before the injury — or, if it's higher, the total family benefit on your record (everything payable to you and any family members before the offset). For most workers, 80% of earnings is the higher one, so that's the cap that governs. This is Section 224 of the Social Security Act, on the books since 1965, and SSA's staff manual for it is POMS DI 52101.

Notice what the rule is *not*. It is not "pick one benefit." It is not dollar-for-dollar confiscation. And it has a floor written into it: the reduction can never leave your combined income below your original SSDI amount — receiving workers' comp can never make you worse off than SSDI alone. The logic Congress wrote in 1965 is almost humble: two disability programs shouldn't, together, pay a person more than they earned while working — because that would make recovery and return-to-work the money-losing option. So the cap sits at 80%, high enough to live on, low enough to keep work worth it.

One more scope line before the math: the offset applies to your SSDI before Full Retirement Age. At FRA, SSDI converts to a retirement benefit (L72) and the workers'-comp offset ends for good. This is a working-years rule, not a forever rule.

Everything turns on one number, so let's build it properly. Your average current earnings (ACE) is SSA's measure of what you were earning before the disability — and SSA computes it three ways and keeps the highest, which is a rule that quietly works in your favor. The three candidates, per POMS DI 52150.010:

• The "high-1" — your single best calendar year of earnings from the window made of the year your disability began plus the 5 years before it, divided by 12. For most people this is the winner, because it captures your peak recent year.
• The "high-5" — your best 5 consecutive years of earnings after 1950, averaged per month. This can win for someone whose best years came earlier in their career.
• The average monthly wage — the unindexed average underlying your benefit computation. It's almost never the highest; it exists as a floor.

Two professional details hide in that list. First, ACE uses your raw, unindexed earnings — no wage indexing (that's a different machine, from L23). Second — and this surprises people — ACE counts your earnings even above the Social Security taxable maximum. If you earned $200,000 in your best year, your ACE is built on $200,000, not on the capped amount that appears on your earnings record for benefit purposes. For a high earner, that makes the cap generous.

Now Marisol. Her best year in the window — the onset year, 2025, plus the five before — was 2024, when overtime pushed her to $54,000. Divide by 12: her ACE is $4,500 a month (the high-1 beats her other two formulas, as it usually does). Her cap is 80% of that: $3,600 a month. Hold that number — it's the ceiling every other figure in this lesson bounces against. And one comparison to keep the fairness of it visible: $3,600 is 80% of her gross pick-line pay, at a time when she no longer pays payroll taxes on it or commuting costs to earn it.

Now the full computation, the way SSA's own examiners run it. Three inputs, then one subtraction. Input one — her SSDI. Marisol's earnings record gives an AIME of $4,300 (the 35-year average machine from L24), and the 2026 formula turns that into a PIA of $2,121.80 — SSA rounding law trims the raw $2,121.88 down to the next lower dime — which pays $2,121 a month (payable amounts round down to the whole dollar, L25). Input two — her workers' comp. Pennsylvania pays her $690.00 a week (about two-thirds of her pre-injury average weekly wage, per the state schedule — illustrative). SSA converts weekly checks to a monthly figure by multiplying by 13 and dividing by 3 — thirteen weeks to a quarter, three months to a quarter — so her WC counts as $2,990.00 a month. Input three — the cap we just built: $3,600.

Read the result the way Marisol eventually did, with relief instead of dread. She does not lose a benefit. She receives $3,600 every month — her full workers' comp plus $610 of SSDI — which is 80% of her old gross earnings. The offset took $1,511 a month off the SSDI check, but the floor held: her combined income stayed far above the $2,121 her SSDI alone would have paid. And the months of SSDI she's *not* receiving still do quiet work for her — she stays fully entitled to SSDI the whole time, which keeps her in the 24-month clock toward Medicare (L66) and keeps every other door that entitlement opens.

A cap set from your old earnings sounds like it should rot with inflation — ten years of rising prices against a ceiling stuck at your 2024 pay. The law anticipated that with two escalators and an exit, and they're worth knowing because each one puts money back.

• COLAs after the offset starts are protected. Once the offset is in place, each January's cost-of-living raise (L29) is added on top of what you receive — the offset doesn't swallow it (POMS calls these protected increases, DI 52150.055). Marisol's $610 SSDI share rises with each COLA even while her WC and cap stand still.
• Every three years, SSA re-figures your ACE — the triennial redetermination — updating it for national wage growth since the offset began. If the refigured cap is higher, the offset shrinks and your SSDI goes up automatically; it's applied only if it helps you, never to cut you.
• The offset ends — completely — when the earlier of two things happens: your workers' comp stops (or a prorated lump sum is used up), or you reach Full Retirement Age, when SSDI converts to a retirement benefit (L72) and §224 no longer applies.

The practical takeaway: an offset notice is a snapshot, not a sentence. Marisol's $610 is the floor of her SSDI story, not the whole of it — COLAs lift it yearly, the 2029 redetermination may lift it again, and the day her WC ends or she reaches 67, the full $2,121 (plus every COLA since) is back.

Now the part of this lesson that most needs to reach people before they sign. Workers'-comp cases very often end in a lump-sum settlement — in Pennsylvania it's called a compromise and release — where the insurer pays one final sum and the weekly checks stop. Eighteen months in, Marisol's insurer offers exactly that: $150,000 to close her wage-loss claim. Her first thought is the right one for this lesson: *the offset compares monthly amounts — what does Social Security do with one big check?* The answer: SSA prorates it — converts it into a pretend monthly rate and keeps the offset running until the lump sum is "used up" at that rate. And the rate SSA uses follows a strict priority order, from POMS DI 52150.060:

1. The rate the settlement document itself specifies — including language spreading the sum over your remaining life expectancy. If the award states a rate, SSA follows the award.
2. If the award is silent: the periodic rate you were being paid before the settlement — for Marisol, her $690/week.
3. If there were never periodic payments: the state's maximum WC rate at the date of injury.

Sit with what that priority order means: the wording of the settlement controls the offset. Before the math, one deduction in Marisol's favor — not everything in the $150,000 counts. Excludable expenses come out first: her state-approved attorney fee ($30,000 here — PA fees are a court-approved percentage) and documented medical amounts are excluded from the offset, leaving $120,000 subject to proration. Now watch the same $120,000 land two completely different ways.

If the settlement is silent about a rate, SSA reaches for priority two — her old $2,990 monthly rate — and the offset simply continues as if the weekly checks never stopped: SSDI stays at $610 for the 40 months it takes to exhaust $120,000 at $2,990 a month ($120,000 ÷ $2,990 ≈ 40.1). If the settlement instead states that the $120,000 is paid in consideration of her remaining life expectancy — 420 months, about 35 years, per the actuarial tables — then the prorated rate is $120,000 ÷ 420 = $285.71 a month. Add that to her $2,121.80 SSDI: $2,407.51 — under the $3,600 cap. The offset ends entirely, and her full $2,121 SSDI is restored from the first month after the settlement.

Every other lesson in this course offers a human; this one practically requires it. A workers'-compensation attorney is who drafts the settlement — the proration language, the allocation of medical amounts, the fee documentation that becomes your excludable expenses — and their pay in a WC case is a percentage set or approved under your state's system (in Pennsylvania, capped at 20% and approved by a judge), taken from the settlement itself, not an extra bill you find later. Before you sign anything: ask the attorney directly, *"how will this settlement's wording affect my Social Security disability offset?"* — the question itself signals what you need drafted, and a competent WC lawyer knows exactly what it means.

Two neighbors of that advice. If your question is about the SSA side — appealing the offset math, representation before Social Security — that's a different representative with a different, federally-capped fee, and L154 walks the whole honest ladder, including the free options. And whatever gets signed, send Social Security a copy of the full settlement document promptly — the proration only helps if SSA has the language in the file (reporting duties in the next-to-last section). SSA itself will answer offset questions free at 1-800-772-1213; what it won't do is draft your state paperwork.

Everything so far assumed the federal side does the trimming. In a minority of states, it runs the other way around: the state's law reduces the workers'-comp benefit when you also get SSDI, and Social Security — to avoid a double cut — pays SSDI in full. These are reverse-offset plans, and SSA honors only the ones already in effect on February 18, 1981, the day Congress froze the list; no state can add one now. Per POMS DI 52105.001, the recognized workers'-comp reverse-offset jurisdictions are fifteen: Alaska, California, Colorado, Florida, Louisiana, Minnesota, Montana, Nevada, New Jersey, New York, North Dakota, Ohio, Oregon, Washington, and Wisconsin.

The geography is almost cinematic for Marisol: the warehouses across the Delaware River hire from the same labor pool she came from — and New Jersey is a reverse-offset state while Pennsylvania is not. Same injury, same pallet, twenty miles east: her SSDI would arrive in full at $2,121, and it would be her New Jersey WC check that got reduced under the state's own formula. Which check shrinks — and whose rules do the shrinking — depends on where the workers'-comp claim is, something almost nobody knows until it happens to them. Two honest cautions: reverse offset often applies to a particular benefit type or period within a state's system rather than every WC dollar (each state's plan has its own scope), and workers' comp itself is state law throughout — rates, caps, settlement names all vary. Your state's rule is a one-question call to your WC attorney or to SSA at 1-800-772-1213.

Two practical edges close out the mechanics. First, the reporting duty. SSA computes your offset from what it knows about your workers' comp — so you must report every WC event: payments starting, the amount changing, payments stopping, and any lump-sum settlement, with the full document. Report promptly (the general duty is L112) and the offset stays correct in real time. Let a change slide — say, WC ends and you don't mention it — and SSA under- or over-pays you until the records catch up, which is precisely how overpayment letters (L114) get born. Every offset dollar is eventually reconciled; reporting just decides whether it happens smoothly now or painfully later. And keep every offset notice — if SSA's math uses a wrong WC amount or a wrong ACE, you can appeal within 60 days (+5 mailing days) like any determination.

Second, the tax wrinkle. Workers' comp itself is famously not taxable. But here's the twist, straight from IRS Publication 915: the part of your workers' comp that caused an SSDI reduction is treated as a Social Security benefit for tax purposes — it lands in box 5 of your SSA-1099 (L89) as if SSA had paid it. Marisol's SSA-1099 will show roughly her full $2,121.80-a-month benefit level, not the $610 she cashed — because the $1,511.80 offset portion of her WC is counted as Social Security income under the L88 provisional-income rules. Whether any of it is actually taxed depends on her total income exactly as L88–L89 teach — for many people the answer is still little or nothing — but the 1099 surprise is real, and now it won't be a surprise.

Half the panic around this topic comes from people applying the offset to benefits it never touches. The short list of non-triggers, each with its home lesson:

• VA benefits — never. VA disability compensation and Social Security stack in full, with no offset in either direction (L126, on Ray).
• A non-work injury or illness — never. No workers'-comp claim means nothing to offset: Terrence's full $2,217 was never touched (his disc disease wasn't a workplace injury).
• SSI is a different machine. For SSI, workers' comp isn't "offset" — it's simply counted as unearned income under the L75 rules (concurrent SSDI+SSI cases: L84).
• Private long-term-disability insurance. SSA does not reduce SSDI for a private LTD policy. The reduction you may have heard of runs the other way: most LTD policies cut *their own* payment by your SSDI — that's the insurer's contract, not Social Security's doing.
• Certain other PUBLIC disability benefits DO trigger it — a state temporary-disability check, some government disability pensions from non-covered work. Same §224 machinery, its own edge cases: L125, next door.

One sentence to carry: this offset lives only where a workers'-comp or public-disability check and SSDI overlap before FRA — everywhere else, your benefits simply stack.

An injured worker with a pending settlement is carrying the most money they've ever had on paper and the least certainty they've ever felt — which makes this exact topic a hunting ground. The pitches: a "benefits-maximization advisor" who'll "structure your comp and SSDI to beat the offset" for an up-front fee; a settlement mill promising a "government-approved offset waiver"; a caller who "needs your SSN and bank login to re-file your offset paperwork."

The tell that unmasks every version: the offset is a public formula — 80% of ACE, printed in the law, computed by SSA for free — and there is nothing to unlock. The one legitimate lever is the settlement's proration language, and the professional who drafts it — a workers'-comp lawyer — is paid a state-approved percentage of the settlement, disclosed in the settlement documents themselves, never a separate up-front "maximization fee." Anyone selling secret access to a formula you can read yourself is lying. If it happens to you, being targeted is never your fault: report it to SSA's Office of the Inspector General at oig.ssa.gov, call SSA at 1-800-772-1213 (TTY 1-800-325-0778), and file with the FTC at reportfraud.ftc.gov.

Maybe you're reading this lesson too late in one sense: the settlement is signed, it never mentioned proration, and the last section felt like a description of money you already lost. Set the self-blame down first. Nobody hands an injured worker a guide to §224 at the settlement table; you signed what was in front of you, like everyone does.

Now the honest inventory of what's still true. The offset ends — at your workers'-comp exhaustion or at FRA, whichever comes first, your full SSDI returns, with every COLA since preserved. The cap self-corrects — protected COLA increases and the triennial ACE redetermination push your payable amount up over time without you lifting a finger. The math can be checked — offset determinations carry the same 60-day (+5 mailing) appeal rights as anything else SSA decides, and wrong WC amounts and wrong ACEs do get fixed. Even the wording isn't always final — some states allow an amended award, and SSA reads a genuine amendment under your state's law; a workers'-comp attorney can tell you in one consultation whether that door exists for you (no one, including us, should promise what's behind it). And if the offset ever produced an overpayment, the waiver-and-appeal routes of L115 apply in full. The route that helps: your award notices + 1-800-772-1213 for the federal math, a WC attorney for the state paperwork, and L154 for finding representation whose fees are capped and honest.

The questions injured workers actually ask when workers' comp and SSDI land in the same mailbox.

• "Can I really get workers' comp and SSDI at the same time?" Yes — plenty of people do. The only rule is the cap: together they can't exceed 80% of your average current earnings (or your family's total benefit, if higher). Under the cap, both pay in full; over it, SSDI is trimmed to the cap.
• "Which check gets reduced?" Usually SSDI — the federal side yields. In the 15 reverse-offset states (frozen since 1981 — including New Jersey, California, New York, Ohio…), it flips: the state cuts the workers'-comp check and SSDI arrives in full.
• "How is the cap actually figured?" 80% of your ACE — and ACE is the highest of three formulas, usually your single best earnings year from the onset year plus the five before, divided by 12. It uses raw earnings, even above the taxable maximum.
• "Does a lump-sum settlement end the offset?" No — SSA prorates it into a monthly rate and keeps the offset running until the sum is used up at that rate. The rate follows the settlement's own wording first, which is exactly why the wording matters.
• "Should I get a lawyer before signing the settlement?" The proration paragraph, the medical allocation, and the excludable-fee documentation are drafting work — a WC attorney's job, paid a state-approved percentage of the settlement. Ask them directly how the wording affects your Social Security offset. (SSA-side representation and its capped fees: L154.)
• "My disability isn't from a work injury — does any of this hit me?" No. No workers'-comp claim, no offset — your SSDI is untouched, like Terrence's $2,217. (Other *public* disability benefits can trigger the same machinery — L125.)
• "Is the offset forever?" No. It ends when your WC stops (or the prorated lump sum runs out) or at Full Retirement Age, when SSDI converts to retirement (L72). Meanwhile COLAs are protected and the ACE is re-figured every 3 years — the squeeze loosens over time.
• "Why does my SSA-1099 show more than SSA paid me?" Because the offset portion of your workers' comp is treated as a Social Security benefit for taxes (IRS Pub 915). It lands in box 5 even though the state paid it. Whether any is actually taxed follows the ordinary L88–L89 rules.

Run the machine you just learned. The calculator starts loaded with Marisol — ACE $4,500, workers' comp $2,990 a month, SSDI $2,121.80 — and shows the cap, the excess, and the SSDI that survives. Then flip the lump-sum switch and watch the same $150,000 settlement land under silent wording versus life-expectancy wording; the gap between those two panels is this lesson's entire warning, in dollars. Change any input and the offset re-runs live.

As always: this illustrates the rules on our named person's teaching figures — it never computes your benefit and never predicts what any settlement will do. Your real numbers are on your SSA notices and your *my Social Security* account (L11); your settlement questions belong with a workers'-comp attorney before you sign; and the federal math is a free call to SSA at 1-800-772-1213.

• Workers' compensation (WC): your state's insurance for on-the-job injury and illness — wage-loss checks and medical care, run under state law with state rates. Not an SSA program.
• The WC/PDB offset (§224): the federal rule (since 1965) that trims SSDI when SSDI plus workers' comp (or certain public disability benefits — L125) would exceed the applicable limit. A cap, not a cancellation.
• Average current earnings (ACE): SSA's measure of your pre-disability earnings — the highest of three formulas, computed on raw unindexed earnings, even above the taxable maximum.
• High-1 / high-5: the two ACE formulas that usually compete — your best single year from the onset year plus the 5 before (÷12), or your best 5 consecutive years after 1950 (averaged monthly). High-1 usually wins.
• The applicable limit: the offset ceiling — the higher of 80% of your ACE or the total family benefit on your record. Combined WC + benefits get trimmed down to this line, never below your original SSDI.
• Lump-sum settlement (compromise and release): the one-time payment that ends a WC case. SSA prorates it into a monthly rate and continues the offset until it's used up.
• Proration / settlement language: how the settlement document states the sum is paid (a stated rate, a life-expectancy spread…). SSA follows the award's own wording first — the reason drafting matters.
• Excludable expenses: amounts inside a WC payment that don't count toward the offset — approved attorney fees and documented medical/legal costs.
• Reverse offset: a state plan (15 recognized WC plans, frozen at February 18, 1981) where the state cuts the WC check instead, and SSDI pays in full.
• Triennial redetermination: SSA's every-3-years re-figuring of your ACE for wage growth — applied only when it raises your payable SSDI.
• Protected increases: COLA raises arriving after the offset begins — added on top of your payable amount, never absorbed by the offset.
• SSDI *(re-gloss; deep home L56):* Social Security Disability Insurance — the benefit your work credits earned, equal to your PIA, convertible to retirement at FRA (L72).
