Is Social Security taxed if it is my only income?

Usually not. If Social Security is your only income, your combined income stays below the thresholds and none of your benefit is taxed. You may not even need to file a federal return.

Does North Carolina tax Social Security benefits?

No. North Carolina does not tax Social Security retirement or disability benefits. You subtract the federally taxed amount on Schedule S of your NC return. Other retirement income, like 401(k) and IRA withdrawals, is taxed at the 3.99 percent flat rate.

What does up to 85 percent taxable actually mean?

It means up to 85 percent of your benefit is added to your taxable income. It is not an 85 percent tax rate. That added amount is then taxed at your normal bracket, such as 12 or 22 percent.

What is the new $6,000 senior deduction?

For tax years 2025 through 2028, people 65 or older can claim an extra $6,000 deduction per person, whether they itemize or take the standard deduction. It phases out above $75,000 of MAGI single or $150,000 joint.

Do the Social Security tax thresholds change each year?

No. The $25,000, $34,000, $32,000, and $44,000 thresholds have been frozen since the 1980s and 1990s. Benefits rise with cost-of-living adjustments, so more retirees cross the thresholds every year.

No. Supplemental Security Income is a needs-based program, not an earned benefit. SSI payments are not taxable at the federal level.

In short

The IRS uses a number called combined income: your adjusted gross income, plus tax-exempt interest, plus half of your Social Security benefits. Cross the threshold for your filing status and part of your benefit becomes taxable. Stay under it and none of it is.

The 2026 thresholds

Federal Social Security taxation thresholds for 2026
Filing status	Combined income	Share of benefit taxable
Single, head of household	Under $25,000	0 percent
Single, head of household	$25,000 to $34,000	Up to 50 percent
Single, head of household	Over $34,000	Up to 85 percent
Married filing jointly	Under $32,000	0 percent
Married filing jointly	$32,000 to $44,000	Up to 50 percent
Married filing jointly	Over $44,000	Up to 85 percent

Example: a single retiree with $20,000 of pension income and $18,000 of Social Security has combined income of $29,000 ($20,000 plus half of $18,000). That falls in the 50 percent band, so part of the benefit is taxable.

The 85 percent cap, explained

When people hear 85 percent, they picture an 85 percent tax rate. That is not how it works. At most 85 percent of your benefit is added to your taxable income. That amount is then taxed at your normal bracket. In the 12 percent bracket, you pay 12 percent on that slice. At least 15 percent of your benefit stays untaxed no matter what.

The new $6,000 senior deduction

For tax years 2025 through 2028, taxpayers 65 or older can claim an extra $6,000 deduction per person. It works whether you itemize or take the standard deduction. It phases out when modified adjusted gross income passes $75,000 single or $150,000 joint. It does not change how benefits are taxed, but it can shrink the income your benefits are measured against.

North Carolina's rule

North Carolina does not tax Social Security benefits. On your NC return you subtract the federally taxed amount on Schedule S. Other retirement income, such as 401(k) and IRA withdrawals and pensions, is taxed at the flat 3.99 percent rate. Here is the full picture of taxes in retirement.
