About the Bonus Tax Calculator
The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
Federal withholding: 22% flat rate (IRS percentage method for bonuses under $1M). Add Social Security (6.2%) + Medicare (1.45%) + state tax.
Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.
Formula & How It Works
The calculation applies the following relations exactly as recorded in the metadata: Federal withholding: 22% flat rate (IRS percentage method for bonuses under $1M). Add Social Security (6.2%) + Medicare (1.45%) + state tax. Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.
