- Retirement, SSDI, and Survivors benefits — All follow the same combined-income rules.
- SSI (Supplemental Security Income) — Never taxable.
The 2.8% COLA for 2026 raises benefit amounts. Higher benefits increase your combined income and can move you into a taxable tier even if your other income stays the same.

Combined income = Adjusted Gross Income (AGI) + nontaxable interest + one-half of your Social Security benefits.
These thresholds have not changed in many years:
| Filing Status | Combined Income | Taxable Portion |
|---|---|---|
| Single / Head of Household | Under $25,000 | 0% |
| Single / Head of Household | $25,000 – $34,000 | Up to 50% |
| Single / Head of Household | Over $34,000 | Up to 85% |
| Married Filing Jointly | Under $32,000 | 0% |
| Married Filing Jointly | $32,000 – $44,000 | Up to 50% |
| Married Filing Jointly | Over $44,000 | Up to 85% |
How the Taxable Amount Is Calculated
The IRS does not simply tax 50% or 85% of your benefits. You use the Social Security Benefits Worksheet in the Form 1040 instructions. Here is the clear process:
- Calculate your combined income (AGI + nontaxable interest + half of benefits).
- See which tier you fall into using the table above.
- Apply the official “lesser of” formulas:
- 50% tier: Taxable amount is the lesser of (50% of benefits) or (50% of the amount your combined income exceeds the lower threshold).
- 85% tier: A two-step calculation is used. The final result is limited to 85% of your total benefits.
The taxable portion is added to your other income and taxed at ordinary rates. It is never taxed at a flat 50% or 85% rate.
Senior Deduction Tip (2025–2028): If you are 65 or older, you may claim an extra $6,000 deduction ($12,000 if both spouses qualify). This deduction phases out above $75,000 / $150,000 of income and can significantly reduce or eliminate the tax you ultimately pay on your benefits.
Real-World Examples (2026)
| Situation | Benefits | Other Income | Combined Income | Taxable Portion |
|---|---|---|---|---|
| Single, modest income | $18,000 | $16,000 | $25,000 | $0 |
| Single, middle income | $22,000 | $24,000 | $35,000 | Up to $11,000 (50% tier) |
| Married, moderate | $32,000 | $26,000 | $42,000 | Up to $10,000 (50% tier) |
| Married, higher income | $40,000 | $45,000 | $65,000 | Up to $34,000 (85% tier) |
| Single, higher benefits | $30,000 | $38,000 | $53,000 | Up to $25,500 (85% tier) |
Special Case: Missing Earnings or Worked Under an ITIN
Some people worked for years using an Individual Taxpayer Identification Number (ITIN) or have gaps in their earnings record. Those missing years can lower your benefit amount.
What to do: Schedule an appointment with your local Social Security office. Bring proof of the missing earnings (W-2 forms, pay stubs, tax returns, or employer letters). SSA can review the documents and add the earnings to your record, which may increase your future benefits.

Voluntary Tax Withholding (Form W-4V)
You can have federal tax withheld from your monthly benefit so you do not face a large bill in April.
- Available rates: 7%, 10%, 12%, or 22%
- Submit Form W-4V to SSA or manage it online through your my Social Security account.
- To stop withholding, submit a new form and select “Do not withhold.”
Example: $2,400 monthly benefit with 10% withholding → $240 withheld, $2,160 deposited each month.
Filing Your Taxes & Form SSA-1099
SSA issues Form SSA-1099 every January. You can also download it from your my Social Security account (usually ready in early February).
- Total benefits go on Form 1040, Line 6a
- Taxable amount (from the worksheet) goes on Line 6b
Most tax software completes the worksheet for you automatically.
