Is Social Security taxed in 2026?

Yes, up to 85% of your Social Security benefit can be federally taxable depending on your 'provisional income' (AGI + tax-exempt interest + 50% of SS benefits). The 50% and 85% thresholds were set in 1983 and 1993 and have never been adjusted for inflation, so more retirees hit them every year.

What is the provisional income formula for Social Security?

Provisional income = your AGI (excluding SS) + tax-exempt municipal bond interest + 50% of your Social Security benefits. For MFJ, the thresholds are $32K (50% taxable) and $44K (85% taxable). For Single, $25K and $34K. The calculator does this math automatically.

Does California tax Social Security?

No, California does not tax Social Security benefits at the state level. Neither do most retirement-friendly states. But the federal tax on up to 85% of your benefit still applies.

How can I reduce my Social Security tax?

Lower your provisional income. The big levers: Roth withdrawals (don't count toward provisional income), QCDs from your IRA at age 70½+ (count as RMDs but excluded from AGI), strategic Roth conversions BEFORE you start SS, and tax-loss harvesting to reduce ordinary AGI. Our Roth Conversion Calculator models the SS-tax effect of each conversion strategy.

Does the new senior deduction change SS taxation?

Yes. Starting in 2025, taxpayers 65+ get a new $6,000 senior deduction ($12,000 for a couple, phasing out above $75,000 single / $150,000 joint MAGI) on top of the existing extra standard deduction for 65+ ($2,050 single / $1,650 each married for 2026), and the calculator includes both. They reduce taxable income, not provisional income, so they do not change how much of your Social Security is taxable, but they can shrink or erase the tax on it.

Will Social Security ever stop being taxed?

Despite political proposals, there's no current law repealing SS taxation. Planning should assume the current rules continue. Until repeal happens, the provisional-income math is what determines what you keep.

Short answerUp to 85% of your Social Security benefit can be taxable in 2026, depending on combined income: your adjusted gross income plus tax-exempt interest plus half your benefit. Below $25,000 single or $32,000 married filing jointly, none is taxed. Above $34,000 single or $44,000 joint, up to 85% is. Source: IRS Publication 915, checked October 18, 2026.

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.

Eight states still tax Social Security at the state level in 2026, on top of federal: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah and Vermont. See the state-by-state list. 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 modified adjusted gross income over $150,000 (joint) or $75,000 (single). For this deduction that means your adjusted gross income; tax-exempt interest is not added. 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.
