Many retirees assume that Social Security benefits are completely tax-free.
While that is true for some seniors, others may have to pay federal income tax on a portion of their Social Security benefits depending on their total income.
Understanding the 2026 federal tax brackets, Social Security taxation rules, and income thresholds can help retirees estimate their tax liability and make better retirement income decisions.
Do Seniors Pay Taxes on Social Security Benefits?
Age alone does not determine whether your Social Security benefits are taxable.
Instead, the IRS looks at your combined income, which includes:

- One-half of your Social Security benefits
- Adjusted gross income
- Tax-exempt interest income
If your combined income exceeds certain thresholds, up to 85% of your Social Security benefits may become taxable.
It is important to understand that this does not mean you pay an 85% tax. It means that up to 85% of your benefits may be included as taxable income when calculating your federal income tax.
2026 Social Security Tax Thresholds
The IRS uses the following income thresholds to determine whether benefits become taxable.
Single Filers
| Combined Income | Taxable Portion of Benefits |
|---|---|
| Less than $25,000 | None |
| $25,000–$34,000 | Up to 50% |
| Over $34,000 | Up to 85% |
Married Filing Jointly
| Combined Income | Taxable Portion of Benefits |
|---|---|
| Less than $32,000 | None |
| $32,000–$44,000 | Up to 50% |
| Over $44,000 | Up to 85% |
These income thresholds have remained unchanged for many years, meaning more retirees may owe taxes on Social Security benefits as retirement income increases.
How Combined Income Is Calculated
Combined income is calculated using this formula:
- Adjusted Gross Income
- Plus tax-exempt interest
- Plus one-half of your Social Security benefits
This total determines whether any portion of your benefits becomes taxable.
2026 Federal Tax Brackets for Seniors
Seniors use the same federal income tax brackets as all other taxpayers. There is no separate tax table based solely on age.
For many retirees, the most common federal tax rates are:
| Tax Rate | Applies to Taxable Income* |
|---|---|
| 10% | Lowest taxable income levels |
| 12% | Lower-middle income |
| 22% | Moderate income |
| 24% | Higher income |
| 32% | Upper-middle income |
| 35% | High income |
| 37% | Highest income |
*The income ranges depend on your filing status and are adjusted annually.
Additional Deduction for Seniors
For the 2026 tax year, many taxpayers age 65 and older may qualify for an additional federal deduction if they meet the eligibility requirements.
Potential benefits include:
- Additional deduction for eligible seniors
- Additional deduction for each qualifying spouse
- Available even if you claim the standard deduction
- Subject to income limitations
This deduction may reduce taxable income and lower your overall federal tax bill.
Standard Deduction Still Matters
Many retirees do not itemize deductions.
Instead, they claim the standard deduction, which often eliminates federal income tax for seniors with modest retirement income.
If your itemized deductions exceed the standard deduction, itemizing may produce greater tax savings.
Social Security COLA and Taxes
Each year, many retirees receive a Cost-of-Living Adjustment (COLA).
Although larger benefit checks help offset inflation, they can also increase combined income.
As a result, some seniors who previously paid no federal tax on Social Security may find that a portion of their benefits becomes taxable.
Retirement Income That May Affect Social Security Taxes
Several income sources can increase the taxable portion of your Social Security benefits.
These include:
- Traditional IRA withdrawals
- Traditional 401(k) withdrawals
- Pension income
- Part-time employment
- Interest income
- Dividend income
- Capital gains
- Rental income
The more taxable income you receive, the more likely it is that part of your Social Security benefits will become taxable.
Income That May Not Increase Social Security Taxes
Some income sources may have less impact on Social Security taxation.
Examples include:
- Qualified Roth IRA withdrawals
- Qualified Roth 401(k) withdrawals
- Return of principal
- Certain life insurance proceeds
These sources may help retirees manage taxable income during retirement.
Example
Example: Susan receives:
- Social Security benefits: $30,000
- Pension income: $15,000
- Interest income: $2,000
Combined income equals:
- $15,000 (half of Social Security)
- Plus $15,000 pension
- Plus $2,000 interest
Combined income:
$32,000
Depending on her filing status, part of her Social Security benefits may become taxable.
Married Couple Example
Example: Robert and Linda receive:
- Combined Social Security benefits: $48,000
- IRA withdrawals: $24,000
Combined income equals:
- $24,000 (half of Social Security)
- Plus $24,000 IRA withdrawals
Combined income:
$48,000
Since this exceeds the married filing jointly threshold, up to 85% of their Social Security benefits may become taxable.
Tips to Reduce Taxes on Social Security Benefits
Retirees may be able to lower taxes by carefully managing retirement income.
Strategies may include:
- Spreading IRA withdrawals over multiple years.
- Using Roth retirement accounts for qualified withdrawals.
- Timing capital gains.
- Limiting taxable investment income when possible.
- Working with a tax professional before taking large retirement distributions.
Every taxpayer’s situation is unique, so retirement tax planning can have a significant impact on long-term savings.
