How to use it

Use this planning calculator to estimate how much of expected self-employment profit you may want to reserve for taxes.

Calculation method

The calculator subtracts entered expenses from expected revenue and applies your selected tax set-aside percentage.

Important limitation

This is a planning shortcut only. It does not calculate actual federal tax, state tax, local tax, deductions, credits, or self-employment tax rules.

Example scenario

If expected 1099 revenue is $85,000 and expected business expenses are $15,000, a 25% reserve would estimate an annual, quarterly, and monthly amount to set aside.

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.
