Is Social Security Taxable in 2026? How Much, the 85% Rule, and the States That Tax It

Yes, Social Security can be taxable, but often only part of it, and sometimes none. The federal rule depends on your "provisional income": your other income plus half your benefits. Below $25,000 for a single filer ($32,000 married filing jointly), none of your benefits are taxed. Above that, up to 50% and then up to 85% can be. No more than 85% of benefits is ever taxable. Below: how the IRS formula works, examples, a calculator for your 2026 numbers, what the 2025 tax law did and did not change, and the eight states that still tax benefits in 2026.


The Short Answer

  • Provisional income = your adjusted gross income without Social Security, plus tax-exempt interest, plus half of your benefits.
  • Single, head of household: nothing taxable up to $25,000; up to 50% taxable between $25,000 and $34,000; up to 85% above $34,000.
  • Married filing jointly: nothing taxable up to $32,000; up to 50% between $32,000 and $44,000; up to 85% above $44,000.
  • Married filing separately and living together: up to 85% can be taxable from the first dollar.
  • These thresholds have never been adjusted for inflation. They are written into IRC section 86, so a larger share of retirees crosses them every year.
  • "Taxable" does not mean "taxed at 85%". It means up to 85% of your benefits is added to your income and taxed at your normal rate, after deductions.

How the IRS Decides: Provisional Income

The IRS formula is Worksheet 1 in Publication 915. Start with the total in box 5 of your Form SSA-1099, your net benefits for the year. Medicare premiums deducted from your check are still part of that figure. Then:

  1. Take half of your benefits.
  2. Add all your other income that goes into AGI (pensions, IRA and 401(k) withdrawals, wages, interest, dividends, capital gains), minus adjustments such as deductible IRA contributions.
  3. Add tax-exempt interest, such as municipal bond interest. It is not taxed itself, but it counts here.
  4. Compare the total with the base amount ($25,000 or $32,000) and the adjusted base amount ($34,000 or $44,000).

Between the two amounts, the taxable part is the smaller of half your benefits and half the income above the base amount. Above the adjusted base amount, it is 85% of the income above that line plus a capped piece from the 50% zone, up to the limit of 85% of benefits.

The practical effect is a "tax torpedo". While you are in the 50% or 85% zone, each extra dollar of other income also makes 50 or 85 cents of benefits taxable. In the 12% bracket, that turns 12% into 18% or 22.2% on each extra dollar of IRA withdrawals, until 85% of your benefits are taxable.

Hypothetical. Taxable benefits per IRC section 86 / Pub 915 Worksheet 1; tax per 2026 brackets and deductions (Rev. Proc. 2025-32, P.L. 119-21). "Federal tax caused by benefits" is the tax with the benefits minus the tax without them. Our arithmetic.

Notice the second and fifth rows: part of the benefits is taxable, yet no tax is due, because the 2026 deductions for people 65 and older cover it. Taxable benefits and actual tax are two different questions.

Did the 2025 Law End Tax on Social Security?

No. The One Big Beautiful Bill Act (Public Law 119-21) did not change section 86, so the rules above still decide how much of your benefits is taxable. What it added is a new $6,000 deduction for each person 65 or older, for tax years 2025 through 2028. The deduction shrinks by 6% of modified AGI above $75,000 ($150,000 joint), married couples must file jointly to claim it, and it applies whether or not you receive Social Security.

The Social Security Administration said in a July 3, 2025 press release that the law "ensures that nearly 90% of Social Security beneficiaries will no longer pay federal income taxes on their benefits." That is an estimate of the deduction's effect, not a change to how benefits are taxed. Whether you owe tax still depends on your own income: in the examples above, people with modest other income owe nothing, while the couple with $60,000 of other income still owes $4,344 because of their benefits.


States That Tax Social Security in 2026

Most states with an income tax exempt Social Security. For tax year 2026, eight states tax at least some benefits for some residents:

State2026 rule
ColoradoAge 65 and older: benefits fully exempt. Age 55 to 64: fully exempt if AGI is $75,000 or less ($95,000 joint), otherwise up to $20,000 can be subtracted. Under 55: taxed.
ConnecticutFully exempt if federal AGI is under $75,000 ($100,000 joint or head of household). Above that, at most 25% of benefits is taxed.
MinnesotaSubtraction phases out above AGI of $110,780 (joint), $86,410 (single, head of household) or $55,390 (married filing separately), shrinking 10% for each $4,000 over ($2,000 if married filing separately).
MontanaTaxed to the extent it is federally taxable. Residents 65 and older get a general subtraction ($5,660 for 2025, indexed each year).
New MexicoFully exempt if AGI is $100,000 or less ($150,000 joint, $75,000 married filing separately). Above the limit, no exemption.
Rhode IslandExempt if you have reached full retirement age and AGI is under an indexed limit ($107,000 single, $133,750 joint for 2025; 2026 limits not yet published).
UtahTaxed, with a credit that shrinks by 2.5 cents per dollar of income above $54,000 single, $90,000 joint or head of household, $45,000 married filing separately.
VermontFully exempt up to AGI of $55,000 single, phasing out to $65,000; $70,000 joint, phasing out to $80,000.

Stat. 290.0132 and MN DOR 2026 inflation-adjusted amounts, Montana DOR 2025 instructions, NMSA 7-2-5.14, RI Division of Taxation, Utah Code 59-10-1042, 32 V.S.A. 5830e). Vermont's tax department web page still shows older thresholds; the figures above are from the statute as amended in 2025.

Recent repeals: West Virginia exempts 100% of benefits from tax year 2026. Kansas, Missouri and Nebraska stopped taxing benefits from tax year 2024 (in Missouri, the law covers retirement benefits from age 62 and disability benefits at any age). States without a broad income tax do not tax benefits at all. State rules change often, so check your state's 2026 instructions before you file.


Paying the Tax: Withholding and Estimates

Social Security does not withhold federal tax unless you ask. To start, file IRS Form W-4V with the Social Security Administration and choose 7%, 10%, 12% or 22% of each payment; the form allows no other percentages or dollar amounts. The alternative is quarterly estimated tax payments. If too little is paid during the year, you can owe an underpayment penalty; the safe harbors are explained in our Roth conversion guide.


Ways to Keep More of Your Benefits Untaxed

  • Give to charity from your IRA. From 70½, a qualified charitable distribution leaves your income entirely, which lowers provisional income too.
  • Time IRA withdrawals and Roth conversions. Years before you claim Social Security, when benefits cannot be taxed, are often the cheapest time to draw down or convert traditional IRAs. Our Roth conversion calculator shows the torpedo effect.
  • Use Roth money. Qualified Roth IRA withdrawals are not part of AGI, so they do not count toward provisional income.
  • Remember that municipal bond interest counts. It is tax-free itself but raises provisional income.
  • Watch one-time income. A large capital gain or IRA withdrawal in one year can push benefits into the 85% zone for that year only.

Special Cases

  • Back payments for earlier years. If a lump sum includes benefits for prior years, you can refigure the taxable part using each earlier year's income and use the lower result, without amending the old returns. Pub 915 has the worksheets; you check the box on Form 1040 line 6c.
  • Railroad Retirement. The Social Security equivalent part of Tier 1 benefits (Form RRB-1099) is treated the same way.
  • Nonresident aliens. 85% of benefits is taxed at a flat 30% unless a tax treaty exempts them or sets a lower rate.
  • Disability and survivor benefits follow the same rules as retirement benefits, based on the recipient's income. Benefits a child receives are counted for the child, not the parent.

Sources & Methodology

  • IRS Publication 915 (2025) and IRC section 86 (govinfo): Worksheet 1, base amounts, lump-sum election, railroad and nonresident rules.
  • IRS Form W-4V (January 2026): withholding percentages.
  • Public Law 119-21, section 70103: the senior deduction; Rev. Proc. 2025-32: 2026 brackets and standard deduction.
  • Social Security Administration press release of July 3, 2025, on the One Big Beautiful Bill (Wayback Machine copy).
  • State statutes and revenue department publications listed under the state table; West Virginia Code 11-21-12, K.S.A. 79-32,117, RSMo 143.125 and Neb. Rev. Stat. 77-2716 for the repeals.

Method notes. The examples and calculator are our arithmetic: we compute the 2026 federal return with and without the benefits, using the same engine as our Roth conversion calculator. State rules were checked against each state's law or revenue department on October 12, 2026; Rhode Island's and Montana's 2026 inflation-adjusted amounts had not been published, so 2025 figures are shown.

FAQ

At what age is Social Security no longer taxable?
There is none. The rules depend on income, not age. The senior deduction from age 65 can reduce or remove the tax, but it does not make benefits non-taxable.

Is Social Security taxed at 85%?
No. At most 85% of your benefits is counted as taxable income, and that amount is taxed at your normal bracket rate after deductions.

How much can I earn before Social Security is taxed?
Federal tax can start once your provisional income (other income plus tax-exempt interest plus half your benefits) passes $25,000 single or $32,000 joint. Even then, the standard deduction often means little or no tax is due.

Do Medicare premiums reduce taxable Social Security?
No. Box 5 of Form SSA-1099 includes the Medicare premiums withheld from your benefits.

Is Social Security disability (SSDI) taxable?
Under the same rules as retirement benefits. Many SSDI recipients owe nothing because their other income is low.
