Question 1

Is Social Security taxable?

Accepted Answer

It can be. Whether any of your benefits are taxable depends on your "provisional income": your other income plus tax-exempt interest plus half of your benefits. Below the base amount none is taxable, and at most 85% of benefits is ever taxable.

Question 2

What are the income thresholds?

Accepted Answer

For single filers, benefits become taxable when provisional income is above $25,000, and up to 85% is taxable above $34,000. For married couples filing jointly the thresholds are $32,000 and $44,000. These amounts are set by law and are not adjusted for inflation.

Question 3

Does 85% mean I pay 85% tax?

Accepted Answer

No. It means up to 85% of your benefits is added to your taxable income. You then pay your normal tax rates on it, after the standard deduction.

Question 4

Does the new senior deduction help?

Accepted Answer

Yes. For 2025 through 2028 people 65 and older can deduct an extra $6,000 each, subject to an income phase-out. It lowers taxable income but does not change how much of your benefits is taxable, because that is based on income before deductions.

Question 5

Do states tax Social Security?

Question 6
