Combined Income Calculation
How SSDI Taxation Works in 2026
Social Security Disability Insurance (SSDI) is taxed using the same rules as Social Security retirement benefits. The IRS uses "combined income" (also called provisional income) to determine how much of your SSDI is taxable.
2026 Thresholds
Important: VA Disability vs SSDI
VA disability compensation is 100% federal tax-exempt and does NOT count toward combined income. This means veterans receiving both VA disability and SSDI have a significant tax advantage β the VA income does not push SSDI into the taxable zone.
Workers Compensation Offset
Workers compensation can reduce your actual SSDI check via the "workers comp offset" if combined workers comp + SSDI exceeds 80% of your pre-disability earnings. The offset applies to SSDI, not to workers comp itself. This reduces your net SSDI benefit but does not change the taxation rules on the SSDI you do receive.

Strategy Comparison: Traditional IRA vs Roth Withdrawals
Assuming $10,000 needed from retirement savings. Traditional IRA adds to AGI (increases combined income). Roth IRA does not count toward combined income at all.
