Frequently Asked Questions

What is the standard deduction for 2026?

For 2026, the standard deduction is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for head of household. These amounts are adjusted annually for inflation.

What is the difference between marginal and effective tax rate?

Your marginal rate is the tax rate on your last dollar of income (your highest bracket). Your effective rate is the average rate across all income, which is always lower than the marginal rate.

What are the 2027 tax brackets for married filing jointly?

The IRS publishes official tax-year-2027 brackets around October 2026. Until then, the latest confirmed schedule is tax year 2026 (IRS Rev. Proc. 2025-32) — the brackets that apply to the return filed in 2027. For married filing jointly: 10% up to $24,800, 12% up to $100,800, 22% up to $211,400, 24% up to $403,550, 32% up to $512,450, 35% up to $768,700, and 37% above that.

How much wider are married filing jointly brackets than single brackets?

Through the 32% bracket, married filing jointly thresholds are almost exactly double the single-filer thresholds. For example, the 22% bracket starts at $50,400 for single filers and $100,800 for married filing jointly. Above the 32% bracket, the thresholds are not fully double, which is one source of the so-called marriage penalty for high-earning couples.
