2026 federal tax brackets for married filing jointly

How marginal brackets actually work

The single most common tax misconception is "I crossed into a new bracket so all my income is taxed higher." That's wrong. Federal income tax is marginal — only the income above each threshold is taxed at the higher rate.

Example: A married couple with $200,000 of taxable income doesn't pay 24% on all $200,000. They pay:

• 10% on the first chunk
• 12% on the next chunk
• 22% on the next chunk
• 24% only on the portion above the 24% threshold

The blended (effective) rate ends up much lower than 24%.

The 2026 brackets (married filing jointly)

These are the inflation-adjusted brackets for income earned in 2026. Confirm exact dollar thresholds with the IRS Revenue Procedure for 2026, as the figures move slightly each year:

The 2026 standard deduction for married filing jointly is $32,200 (single $16,100; head of household $24,150). Subtract that from your gross income to get taxable income before applying the brackets. Taxpayers age 65+ get an additional standard deduction of $1,650 per qualifying spouse, plus the new $6,000 senior deduction (phasing out at 6% over $150,000 MFJ MAGI) created by OBBBA.

A worked example

Married couple, both age 60, gross income of $250,000. Standard deduction $32,200. Taxable income $217,800.

• 10% bracket: $24,800 × 10% = $2,480
• 12% bracket: ($100,800 − $24,800) × 12% = $76,000 × 12% = $9,120
• 22% bracket: ($211,400 − $100,800) × 22% = $110,600 × 22% = $24,332
• 24% bracket: ($217,800 − $211,400) × 24% = $6,400 × 24% = $1,536

Total federal tax: ~$37,468 Marginal rate: 24% (the bracket their top dollar is in) Effective rate: $37,468 ÷ $250,000 = 15.0%

Notice the effective rate is far below the marginal rate. That's the marginal-vs-effective distinction.

Why this matters for planning

Almost every tax planning move comes down to the difference between current marginal rate and future marginal rate. Roth conversions make sense if your future marginal rate will be higher than your current one. Tax-loss harvesting makes sense if your current capital gain rate is high relative to your future rate. Capital gain harvesting in 0% bracket years makes sense if you're temporarily in a very low income year.

Bottom line

2026 brackets for MFJ are 10/12/22/24/32/35/37, applied marginally above the $32,200 standard deduction, made permanent by OBBBA. Your effective rate is almost always meaningfully lower than your marginal rate. Plan around marginal because that's the rate the next dollar of income or deduction actually moves.
