What the result means

The result compares your current federal tax rate with an alternative rate and shows how the rate change may affect tax and net income. Federal results are estimates only.

Federal Tax = Federal Taxable Income × Federal Rate - Tax Credits

Federal tax results may vary by tax year, filing status, deductions, credits, and individual circumstances.

Example calculation

For $85,000 taxable income, a 22% current rate, a 24% alternative rate, and $2,000 credits, the current tax is $16,700 and the alternative tax is $18,400.

Tips for better results

  • Keep source records for income, payments, deductions, and credits.
  • Use conservative rates when planning cash reserves.
  • Compare the estimate with related federal and state calculators.
  • Review assumptions before using the result for budgeting.
