Social Security does not become tax-free simply because you reach age 70. Whether your benefits are subject to federal income tax depends primarily on your combined income and filing status, not your age. Other retirement income, including 401(k) or individual retirement account (IRA) withdrawals and pensions, can increase how much of your Social Security is taxable. For retirees over 70, newer deductions may also affect the final tax bill.
A financial advisor can help you figure out how Social Security fits into your retirement plan.
What Is Social Security?
Social Security is a government program created in 1935 as a part of President Franklin Delano Roosevelt’s New Deal, a series of programs designed to fight the Great Depression. It’s considered by most people to be the cornerstone of America’s social safety net. Social Security sends monthly checks to Americans who have reached retirement age, with retirement benefits available as early as age 62 and full retirement age ranging from 66 to 67, depending on birth year.
The monthly payment depends on how much money you earned during your career, and your retirement age. The program is funded by Social Security taxes taken out of each American worker’s paychecks. The average monthly benefit for retired workers in September 2026 was $2,088. 1 Meanwhile, the maximum monthly benefit for a person retiring in 2026 at age 70 is $5,181. 2
Social Security and Federal Taxes

Even though Social Security money comes from the government, some of it may face federal income taxes. How much you owe depends on your income and filing status.
The IRS uses a formula to determine the tax rate for your Social Security check. Essentially, the IRS counts half as combined income, along with other forms of retirement income and any tax-exempt interest. Depending on your total combined income, the IRS could tax up to 85% of your benefits.
Is Social Security Taxable After Age 70?
Some believe Social Security payments become tax-free once you reach a certain age, such as 70. However, this is not true. Social Security payments can remain taxable throughout retirement, regardless of when you began collecting them.
As we explained in the previous section, the key to understanding Social Security taxation is based on your total income and not your age.
So, a single tax filer with a combined income of $25,000 or less avoids taxes. But, if your combined income is between $25,000 and $34,000, up to 50% of your benefits will be taxable. And, for combined income above $34,000, up to 85% of your benefits may be taxable.
For married couples filing jointly, the tax-free limit is $32,000. For those with a combined income between $32,000 and $44,000, up to half of your benefit will be taxable. And, for combined income above $44,000, up to 85% of your benefits may be taxable.
These rules apply even after age 70.

Social Security and State Taxes
Some of the confusion over the tax status of Social Security payments likely comes from the fact that each state treats Social Security differently. In 2026, most states do not impose income taxes on Social Security benefits. A smaller number tax some benefits, often with exemptions based on age or income.
Other states only partially tax Social Security. The amount subject to tax depends on each state’s tax rules, which may differ from the federal calculation.
Finally, some states don’t tax Social Security at all. For some of these states it is a special carveout. For others, it’s simply because there is no state income tax. In that case, none of your retirement income will be subject to any state tax.
How the 2026 Senior Deduction Can Affect Taxes After Age 70
A taxpayer who is 70 or older may qualify for a deduction of up to $6,000 on a 2026 federal return. This provision applies through 2028. Married couples filing jointly may claim up to $12,000 if both spouses qualify. The amount available begins to decrease when modified adjusted gross income exceeds $75,000 for an individual or $150,000 for joint filers. 3
Consider a single retiree, age 72, who receives $30,000 from Social Security and withdraws $25,000 from a traditional IRA during 2026. Assume there is no other income, tax-exempt interest or adjustment to income. The following calculation shows how much of the retiree’s income remains taxable after the available deductions.
| Calculation | Amount |
|---|---|
| Social Security received | $30,000 |
| Traditional IRA withdrawal | $25,000 |
| Combined income ($25,000 + half of $30,000) | $40,000 |
| Social Security included in federal income | $9,600 |
| Adjusted gross income ($25,000 + $9,600) | $34,600 |
| 2026 standard deduction for single filers | −$16,100 |
| Additional standard deduction for age 65 or older | −$2,050 |
| 2026 senior deduction | −$6,000 |
| Federal taxable income | $10,450 |
The $9,600 Social Security figure comes from applying the federal benefit-inclusion formula to $40,000 in combined income. Without the $6,000 senior deduction, the retiree would have $16,450 in taxable income. With it, taxable income is $10,450.
Under the 2026 federal tax brackets for single filers, that difference would lower the retiree’s calculated income tax from $1,702 to $1,045 before credits, a reduction of $657. The figures assume the retiree is eligible for the full deduction and has no other relevant tax items.
Bottom Line

Social Security benefits can still be subject to federal income tax after age 70. The amount included in taxable income depends on your combined income and filing status, while state treatment varies depending on where you live. Other retirement income, such as IRA withdrawals, can increase the taxable portion of your benefits, while deductions available to older taxpayers may reduce your overall federal tax bill.
