Quick Answer: How Are Social Security Benefits Taxed?
Social Security benefits may be partially taxable depending on your provisional income, which combines your adjusted gross income, nontaxable interest, and 50% of your Social Security benefits. With recent tax changes like the One Big Beautiful Bill (OBBB) Act, retirees 65 and older can now claim additional deductions, potentially lowering the taxable portion of their benefits.
Introduction: Understanding the Taxation of Social Security Benefits
For many retirees, Social Security provides a reliable income stream. However, understanding the taxation of Social Security benefits is critical to preserving your retirement income. The IRS determines taxability based on provisional income, which may include your wages, investment income, and half of your Social Security benefits. Recent legislation, such as the OBBB Act, has added deductions that can reduce your overall taxable income for 2026, making planning more important than ever.
What Is Provisional Income?
Provisional income is the IRS’s method for determining whether your Social Security benefits are taxable. Instead of only looking at your benefit payments, the formula calculates a “combined income” to measure your tax exposure:
Provisional Income Formula:
Adjusted Gross Income (AGI) + Nontaxable Interest (e.g., municipal bonds) + 50% of Social Security benefits = Provisional Income
This number determines the percentage of your Social Security benefits that may be subject to federal income tax.
How Much of Your Benefits Are Taxable?
The IRS uses provisional income thresholds to decide whether 0%, 50%, or 85% of your Social Security benefits are taxable:
| Filing Status | 0% Taxable | Up to 50% Taxable | Up to 85% Taxable |
|---|---|---|---|
| Individual (Single, HOH) | <$25,000 | $25,000 – $34,000 | $34,000+ |
| Married Filing Jointly | <$32,000 | $32,000 – $44,000 | $44,000+ |
It’s important to note that these thresholds are not adjusted for inflation. As your benefits increase due to COLA, you may cross into a higher taxable bracket.
The Senior Deduction Under OBBB
The One Big Beautiful Bill (OBBB) Act introduced an additional tax deduction for seniors in 2026:
- Benefit: Individuals 65+ can deduct $6,000; married couples 65+ can deduct $12,000.
- Impact: This reduces overall taxable income but does not change the percentage of Social Security benefits subject to tax.
- Phase-out: The deduction phases out for MAGI over $75,000 (single) or $150,000 (joint).

Practical Ways to Lower Your Tax Bill
Utilize Qualified Charitable Distributions (QCDs)
If you are 70½ or older, you can transfer up to $111,000 (2026 limit) directly from your IRA to charity. QCDs satisfy your RMD requirement without increasing AGI or provisional income, potentially reducing taxable Social Security benefits.
Strategic Withdrawal Sequencing
By withdrawing from taxable brokerage accounts before traditional IRAs, you can maintain a lower AGI. This strategy helps you stay below Social Security tax thresholds and minimize the “tax torpedo.”
Manage the Earnings Test
For retirees working before reaching Full Retirement Age (FRA), the 2026 earnings limit is $24,480. Exceeding this amount results in $1 withheld for every $2 earned, temporarily reducing benefits. Staying under the limit protects your current Social Security income.
Take Control of Your Retirement Tax Bill
Retirement taxation is complex, but proactive planning allows you to maximize your Social Security benefits. By modeling your provisional income and adjusting withdrawal strategies, you can reduce your federal tax liability and ensure more of your retirement income stays in your pocket.
