This comprehensive guide will provide step-by-step instructions on calculating federal, state, and local income taxes.
Federal Income Tax
Federal income tax is levied on all taxable income earned by individuals and businesses. The Internal Revenue Service (IRS) uses a progressive tax system, meaning that higher earners pay a higher percentage of their income in taxes. The current federal income tax brackets for 2023 are as follows:
| Taxable Income | Marginal Tax Rate |
|---|---|
| $0 – $10,275 | 10% |
| $10,275 – $41,775 | 12% |
| $41,775 – $89,075 | 22% |
| $89,075 – $170,050 | 24% |
| $170,050 – $215,950 | 32% |
| $215,950 – $539,900 | 35% |
| $539,900+ | 37% |

Estimated Taxes
If you are self-employed or do not receive a regular paycheck, you are expected to pay estimated taxes throughout the year. Estimated taxes cover both federal and state income taxes. You can calculate your estimated tax liability by dividing your expected taxable income by 12 and multiplying the result by the applicable tax rates. Estimated tax payments are due on April 15, June 15, September 15, and January 15 of the following year.
