Common questions

Frequently asked questions

Is this an exact self-employment tax calculator?

No. This is a simple planning reserve calculator. Actual tax can depend on filing status, deductions, credits, state taxes, local taxes, and self-employment tax rules.

What tax set-aside percentage should I use?

The percentage is a planning assumption. Many people use a conservative estimate and later adjust it with help from a qualified tax professional.

Why does the calculator use profit instead of revenue?

Self-employment planning often starts with expected business profit, which is revenue minus business expenses. Actual tax rules may treat items differently.
