2026 Standard Deduction

Most filers take the standard deduction rather than itemizing. The 2026 figures rose modestly from 2025 due to inflation indexing.

Looking ahead to 2027

2027 federal brackets and the standard deduction can already be computed from the inflation data published in September 2026, about a month before the IRS confirms them. See our projected 2027 tax brackets — clearly labeled as projections, and replaced with official figures the day they publish.

What changed for 2026

Most 2026 changes are routine inflation indexing — bracket thresholds, the standard deduction, and the Social Security wage base all rose by a few percent. The One Big Beautiful Bill Act, signed in 2025, made several Tax Cuts and Jobs Act provisions permanent and adjusted certain credits and deductions; the calculators here reflect those provisions where they affect 2026 withholding or liability calculations.

Calculators that use 2026 data

The Income Tax Calculator, Paycheck Calculator, Capital Gains Tax Calculator, and Self-Employment Tax Calculator all default to 2026 brackets and let you toggle to 2025 for prior-year comparisons. Per-state pages — for both paycheck and income tax — pull from the same 2026 federal data and layer in state-specific brackets and deductions.

State income tax for 2026

Several states changed rates for 2026: Georgia, Indiana, Kentucky, Mississippi, Montana, Nebraska, North Carolina, Ohio, and Oklahoma all have adjustments effective January 1, 2026. Each state's per-state page reflects the 2026 structure. See Tax Calculators for the full state-by-state directory.

Sources and updates

Federal brackets and standard deductions come from IRS Revenue Procedure 2025-32. The Social Security wage base comes from the SSA contribution and benefit base table. State changes are sourced from each state's department of revenue. We re-review every January for inflation adjustments and mid-year for any retroactive changes.

Frequently asked questions

When do 2026 tax brackets take effect?

2026 brackets apply to income earned in tax year 2026 (January 1 through December 31, 2026), filed in early 2027. They do not retroactively change 2025 returns.

What is the 2026 standard deduction?

The 2026 federal standard deduction is $16,100 for single filers and married filing separately, $32,200 for married filing jointly, and $24,150 for head of household.

What is the 2026 Social Security wage base?

The 2026 Social Security taxable wage base is $184,500. Wages above that limit are not subject to the 6.2% Social Security tax (Medicare still applies).

Which tax year applies to me right now?

The year you earned the income, not the year you file. Income earned during 2026 uses 2026 brackets and is reported on the return you file in early 2027. If you are preparing a return for income earned in 2025, use the 2025 figures instead — most calculators here let you switch years.

Did federal tax rates change for 2026?

The rates themselves did not change — the seven brackets remain 10%, 12%, 22%, 24%, 32%, 35%, and 37%. What changed are the income thresholds where each bracket begins, along with the standard deduction, both adjusted upward for inflation. That means a modest raise does not automatically push you into a higher effective tax position.

How are the 2026 brackets calculated?

The IRS indexes bracket thresholds using chained CPI-U measured over the twelve months ending August 31 of the prior year. Because the formula is fixed, the figures are computable before the IRS publishes them, which is why projections circulate in September and the official revenue procedure follows in October.

When is the 2026 tax filing deadline?

Returns for tax year 2026 are generally due April 15, 2027. When that date falls on a weekend or holiday, the deadline shifts to the next business day. An extension gives you more time to file but not more time to pay — any balance owed is still due on the original deadline.
