Federal income tax on $30,000 (2026)

How the $30,000 tax is calculated (single filer)

Start with $30,000 of gross wages and subtract the 2026 standard deduction of $16,100. That leaves $13,900 of taxable income, which is taxed in layers:

Because only the top slice is taxed at 12%, your effective federal rate is 4.7%. Each additional $1,000 of salary adds about $120 of federal income tax plus $76.50 of FICA.

Federal tax on $30,000 if you’re married

Married couples filing jointly get double the standard deduction ($32,200) and brackets twice as wide, so $30,000 of combined income produces only $0 of federal income tax (0.0% effective). Filing separately, each spouse’s tax is figured on their own income using the single-width brackets — on $30,000 that’s $1,420. A head of household filer with $30,000 owes about $585.

How to pay less tax on $30,000

• Contribute to a traditional 401(k). Putting $3,000 (10% of pay) into a pre-tax 401(k) cuts a single filer’s federal tax from $1,420 to about $1,090 — saving $330.
• Use an HSA if you have a high-deductible health plan ($4,400 self-only limit for 2026).
• Claim credits. Each qualifying child under 17 is worth up to $2,200 through the Child Tax Credit.
• Check the new deductions for qualified tips (up to $25,000) and overtime premium pay (up to $12,500).
