Quick test: half of your Social Security plus all your other taxable income. If that number is over $32,000 (married) or $25,000 (single), part of your SS gets taxed (up to 50%). Over $44,000 (married) or $34,000 (single), up to 85% can be taxed.

What you're looking at, in plain English
The number above is how much of your Social Security check the IRS treats as taxable income this year, based on your other income.
The weird-but-true fact
Social Security can be taxed up to 85%, but only sometimes. If you have very little other income, none of your SS is taxed. If you have a lot, up to 85% of your benefit gets pulled into your taxable income (not 85% in tax, but 85% of the benefit is taxable, then taxed at your regular bracket).
The "provisional income" formula
The IRS adds: your other income + your tax-exempt interest + half of your SS benefit. That total is your "provisional income." Then:
Under $32k (married) / $25k (single) → none of your SS is taxed.
$32k to $44k (married) / $25k to $34k (single) → up to 50% of your SS is taxable.
Over $44k (married) / $34k (single) → up to 85% of your SS is taxable.
These thresholds have been frozen since 1983. They don't adjust for inflation. That's why more retirees pay tax on their SS every year.
Why people get blindsided
You can be in a fine tax position, take a one-time IRA withdrawal (Roth conversion, RMD, home repair), and suddenly $20,000 of SS that was tax-free flips to taxable. The "tax bomb" is real, and it shows up in the year of the extra income.
Nine states still tax Social Security at the state level on top of federal. The numbers above are federal-only.

How the 2026 SS Tax Math Works
What's "provisional income" and why does it matter?
It's the IRS's threshold test for whether your Social Security gets taxed: all your taxable income, plus tax-exempt muni interest, plus 50% of your Social Security. Roth withdrawals don't count. If your provisional income is over $32,000 married ($25,000 single), up to 50% of your SS gets taxed at the federal level. Over $44,000 married ($34,000 single), up to 85% can be taxed.
Why does the calculator say zero tax at $70k retired?
Because the new OBBBA "senior bonus" deduction adds $6,000 per spouse 65+ on top of the standard deduction and the existing senior add-on. For a couple at $70k of mixed retirement income, total deductions reach $47,500 in 2026 ($32,200 standard + $1,650 x 2 for age 65+ + $6,000 x 2 senior deduction), which usually wipes out federal tax entirely. The OBBBA bonus expires after tax year 2028 unless Congress extends it.
When does the OBBBA bonus phase out?
It reduces by 6 cents per dollar of MAGI over $150,000 (joint) or $75,000 (single). Couples are fully phased out at $250,000 MAGI; singles at $175,000. The phase-out applies to each qualifying spouse separately.
Is California tax included?
No. This calculator is federal only. California does not tax Social Security but does tax IRA/401(k) withdrawals, pensions, interest, dividends, and capital gains. Add 4-9% of your taxable non-SS income for a CA estimate.
How accurate is this?
Built on the official 2026 IRS inflation adjustments and OBBBA rules. Provisional income, taxable Social Security, deductions, and bracket math all use current statutory formulas. It does not model itemized deductions, AMT, NIIT, IRMAA Medicare surcharges, RMD interactions, or QBI. Treat it as a planning estimate, not a tax return.
