This is a rough estimate to help you save, not tax advice and not a filing. State tax, credits, deductions, filing status, an S-corp election and a dozen other things change it. Talk to a CPA before you file.

What this assumed

  • A flat planning rate, not a tax return. It ignores deductions, credits, filing status and state tax.
  • Self-employment tax is applied on top of the income rate you choose.

Not tax advice

Tax rules change and vary by state, county and situation. This tool does not know your filing status, deductions or local rates. Confirm anything you plan to file with a tax professional or the current official guidance.

What this tool actually does for you

Who it is for

The problem it points at

The self-employment tax is the one that ruins people. You budget for income tax and forget the 15.3 percent underneath it.

What you walk away with

A percent of every deposit to move to savings the day it lands.

How to use it

Takes about two minutes. Be honest with the numbers, the tool is not going to tell anybody.

  1. Enter what you expect to bring in and what you can deduct.
  2. Pick a rough income tax bracket.
  3. Move that percent of every payment into a separate account. Do it the day it hits.
