2020 Tax Calculator for Individuals

The 2020 tax year introduced a few changes to brackets, standard deductions, and credits. This page explains how to calculate your federal income tax liability using a simple stepbystep method and provides an interactive calculator for quick results.

Key Changes for 2020

• Standard deduction increased to $12,400 for single filers, $24,800 for married filing jointly, and $18,650 for heads of household.
• Tax brackets were widened slightly, reducing the number of taxpayers pushed into higher brackets.
• The child tax credit rose to $2,000 per qualifying child (with up to $1,400 refundable).
• The earned income tax credit (EITC) thresholds were adjusted for inflation.
• Mortgage interest deduction limit remained at $750,000 of acquisition debt for new loans.

StepbyStep Calculation

1. Determine Gross Income Add wages, salaries, tips, interest, dividends, capital gains, and any other taxable income.
2. Subtract Adjustments Contributions to traditional IRAs, student loan interest (up to $2,500), educator expenses, and certain selfemployment deductions reduce gross income to arrive at Adjusted Gross Income (AGI).
3. Apply Deductions Choose the larger of the standard deduction or itemized deductions (medical expenses, state/local taxes, mortgage interest, charitable gifts, etc.). Subtract this from AGI to get Taxable Income.
4. Calculate Base Tax Apply the 2020 tax brackets to the taxable income. The rates are:
   • 10% on the first $9,875 (single) or $19,750 (married filing jointly)
   • 12% on income over that up to $40,125 (single) or $80,250 (joint)
   • 22% up to $85,525 (single) or $171,050 (joint)
   • 24% up to $163,300 (single) or $326,600 (joint)
   • 32% up to $207,350 (single) or $414,700 (joint)
   • 35% up to $518,400 (single) or $622,050 (joint)
   • 37% on anything above those limits
5. Subtract Tax Credits Credits directly reduce tax liability. Common credits for 2020 include:
   • Child Tax Credit
   • Earned Income Tax Credit
   • American Opportunity Credit (education)
   • Savers Credit
6. Add Other Taxes If applicable, add selfemployment tax, additional Medicare tax, or net investment income tax.
7. Account for Withholdings & Estimated Payments Subtract the total tax already paid through payroll withholdings or quarterly estimated payments. The result is either the amount you owe or your refund.
