Tax Calculation
- Broadridge Content
Tax calculation is the process by which you figure out how much you owe in income tax. If you file federal income tax Form 1040, you must compute your adjusted gross income (AGI) and your taxable income before you can calculate your tax. Essentially, your AGI is your total income minus certain adjustments. Your taxable income is your AGI minus your itemized deductions (or your standard deduction) and your exemptions. (Personal exemptions have been permanently suspended.)
