Frequently Asked Questions

What is the standard deduction for 2026 (the return filed in 2027)?

For tax year 2026 — the return most people file in 2027 — the standard deduction is $16,100 for single filers, $32,200 for married filing jointly, $16,100 for married filing separately, and $24,150 for head of household. Source: IRS Rev. Proc. 2025-32.

Why is the standard deduction the same for single and married filing separately?

The IRS sets the married-filing-separately standard deduction equal to the single filer amount ($16,100 for 2026) because each spouse files their own return and reports their own income. Splitting a joint deduction between two separate filers would otherwise double-count the benefit.

What are the 2027 federal tax brackets?

The IRS publishes official 2027 brackets around October 2026. Until then, this calculator uses the latest confirmed schedule — the 2026 IRS brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. For single filers, the 22% bracket starts at $50,400 of taxable income. Thresholds shift up modestly each year for inflation, so 2027 figures will be slightly higher.

What is the difference between marginal and effective tax rate?

Your marginal rate is the rate on your last dollar of income — your highest bracket. Your effective rate is the average rate across all income. With progressive taxation, your effective rate is always lower than your marginal rate.
