Federal tax on $20,000: about $390 in 2026
A single filer earning $20,000 with no pre-tax deductions owes approximately $390 of federal income tax for 2026 — an effective rate of 1.9%, with a marginal bracket of 10%. Add $1,530 of FICA (Social Security + Medicare) and take-home pay lands near $18,080 before state tax. For tax year 2025 (filed in early 2026), the federal income tax is about $425. At this income, refundable credits matter more than brackets: the EITC and the refundable portion of the child tax credit can outweigh the entire federal liability for many households.
