Frequently Asked Questions

Do I need to pay both federal and state SE taxes?

Self-employment tax (SE tax) is a federal tax — there is no state-level self-employment tax. However, most states tax your self-employment income as ordinary income under their regular income tax. Nine states have no income tax at all. The total tax burden shown in this calculator includes both federal SE tax and your state's income tax on self-employment income.

Do state deductions work the same as federal?

Many states follow federal treatment for common deductions like business expenses and SE tax deductions, but not all. Some states don't allow the home office deduction, and state retirement contribution limits or health insurance deduction rules may differ from federal. This calculator applies federal deduction rules, which are a good approximation for most states — consult a local tax professional for state-specific deduction limits.
