Formula Used
The calculator applies the progressive tax rates for 2015 based on your filing status. The formula is:
Taxable Income = Total Income - Deductions
Tax = Sum of (Taxable Income × Rate for each bracket)
The tax is calculated by applying each tax bracket's rate to the portion of income that falls within that bracket.
Worked Example
For a single filer with $50,000 taxable income in 2015:
- First $9,275 at 10% = $927.50
- $9,275 to $37,450 at 15% = $4,316.25
- $37,450 to $50,000 at 25% = $646.25
Total estimated tax = $927.50 + $4,316.25 + $646.25 = $5,890.00
This is an estimate. Actual tax may vary based on your specific situation and other factors not included in this calculation.
