This Federal Income Tax Estimator helps you calculate how much federal tax you might owe or get refunded based on your income, filing status, and deductions for the 2025 tax year. After entering your gross income, pre-tax deductions, and tax withholding, the calculator determines your taxable income and applies simplified IRS tax brackets to estimate your total liability. It then compares your actual withholding to your estimated tax to show whether you can expect a refund or need to pay more. This tool is ideal for planning or preparing to file your taxes early.
