A Pulp Mill Injury Leaves Him on Workers’ Comp. He’ll Lose $7,200 a Year in Combined Benefits When Social Security Disability and Workers’ Comp Overlap
Qualifying for both workers' compensation and Social Security Disability sounds like a financial lifeline, but a federal rule can quietly drain hundreds of dollars from those combined checks every single month before the first payment ever arrives.

A deadly tank collapse at a Washington State pulp mill killed 11 workers in May 2026. The tragedy came amid a troubling workplace safety record: 169 employees had filed injury-related workers’ compensation claims since 2015. For workers whose injuries end their careers, the financial consequences can stretch well beyond the workplace. Even qualifying for both workers’ compensation and Social Security Disability Insurance (SSDI) doesn’t guarantee two full checks.
Consider a hypothetical mill worker whose average current earnings, as calculated by Social Security, were $6,000 a month before his injury. Workers’ comp pays him $3,000 monthly, and he’s approved for another $2,400 in SSDI.
Together, that’s $5,400. Assuming the 80% limit applies, his combined payments would be reduced by $600 a month, or $7,200 a year. In the state of Washington, which check gets cut depends on his age and the type of workers’ compensation he receives.
The surprise is that qualifying for two benefits doesn’t guarantee two full checks. A worker who has already lost the income from a physically demanding job can face another financial setback just when disability benefits begin.
An 80% Ceiling Decides How Much of Your Disability Check Survives
Federal rules generally limit combined workers’ compensation and SSDI payments to 80% of a worker’s average current earnings, or the total family Social Security benefit if that’s higher. Average current earnings are calculated under Social Security’s rules and don’t necessarily match someone’s last paycheck. For our worker, assume the ceiling is $4,800.
His two benefits total $5,400, putting him $600 over the limit. In a state where Social Security applies the offset, his SSDI check would fall from $2,400 to $1,800. In Washington, the state may instead reduce his workers’ compensation.
If that $600 monthly reduction continues for 10 years, it adds up to $72,000. The offset can end when workers’ compensation stops or a lump-sum settlement has been fully accounted for. Social Security’s disability offset also ends at full retirement age, when SSDI converts to retirement benefits.
Washington State Workers May See the Cut on a Different Check
Washington State has a different arrangement. For workers receiving certain Time Loss or Pension benefits, the state generally reduces its workers’ compensation payments when SSDI begins. This is called a reverse offset, and it can leave the Social Security check intact.
There are exceptions. Social Security may reduce SSDI during the retroactive period of a disability award, beginning at age 62, or when a worker receives a permanent partial disability lump sum. The type of payment and timing determine which agency makes the cut.
Settlement Wording Can Shrink or Stretch the Cut
Many workers’ comp cases end in a lump-sum settlement, which Social Security converts into a monthly amount when calculating an offset. The payment period matters. A settlement spread over a longer period, potentially including the worker’s life expectancy, can produce a smaller monthly offset. But Social Security has rules for determining that period and won’t necessarily accept whatever the settlement says.
Some money is left out of the calculation. Liens for unpaid medical bills and attorney fees incurred to win the benefits are treated as excludable expenses. Settlement papers that list those costs clearly lower the amount Social Security counts.
A Tax Quirk Turns Some Tax-Free Comp Into Benefit Income
Workers’ comp is normally tax-free, but a Social Security offset creates a tax wrinkle. When SSDI is reduced because of workers’ compensation, the amount withheld can still count as Social Security income for federal tax purposes. In our example, that could mean another $7,200 a year entering the calculation of taxable benefits. The result differs when Washington State reduces workers’ compensation instead.
That test starts above a base amount of $25,000 for single filers and $32,000 for joint filers. A working spouse’s paycheck can push a couple past it faster than they’d expect. Once Medicare begins, the standard Part B premium, $202.90 in 2026, may also come out of the Social Security payment.
What to Pin Down Before You Sign a Settlement
The hardest mistake to undo is a lump-sum settlement written without the offset in mind. Before signing, ask the attorney to show the monthly proration figure in writing and confirm that medical and legal costs are listed as excluded. A few sentences in that document can shape your income for years.
The second step is easy to skip: find out which agency is applying the cap. In Washington State, a call to the Department of Labor & Industries and a review of your Social Security award letter will show whether your comp or your disability check is the one being reduced. That tells you where to look if the numbers ever seem off.
Every claim has its own details, including injury dates, family benefits and state rules. Before planning around the example above, calculate your own numbers.
