Our calculator provides estimates based on current tax brackets and standard deductions. For precise figures, especially with complex tax situations, we recommend consulting a tax professional. The calculator uses 2023 tax rates and is updated annually.

Yes, the calculator includes estimates for state income taxes based on average state tax rates. If you live in a state with no income tax (like Florida or Texas), your state tax will show as zero. For more precise state tax calculations, please select your specific state in the advanced options.

The calculator includes federal income tax, state income tax, Social Security (6.2%), Medicare (1.45%), retirement contributions, and health insurance premiums. You can add additional deductions like HSA contributions, flexible spending accounts, or other pre-tax benefits in the advanced options.

We recommend recalculating whenever you have a significant life change (marriage, new child, relocation), receive a raise or bonus, or when tax laws change. For most people, reviewing your salary breakdown annually or when tax season approaches is sufficient.
