1099 Tax Set-Aside Calculator

Know exactly how much to save from every 1099 payment. Stop guessing and start saving the right amount for taxes.

A 1099 tax savings calculator eliminates the guesswork from the most stressful part of freelance finances — knowing how much to set aside from every payment. The widely-cited 25-30% rule of thumb is a decent starting point, but your actual savings rate depends on your total income, filing status, state of residence, and whether you also have W2 income.

The best practice is to transfer your set-aside amount to a separate high-yield savings account immediately upon receiving each client payment. This mental separation prevents you from accidentally spending tax money and allows your tax savings to earn 4-5% APY while waiting for quarterly payment deadlines.

How to Use This Calculator

  1. Step 1 — Enter your monthly 1099 income — or average it out if your income fluctuates.
  2. Step 2 — Add any W2 income you receive, which may offset some self-employment tax obligations.
  3. Step 3 — Select your state to get an accurate combined tax savings recommendation.
  4. Step 4 — Start transferring the recommended percentage to a dedicated tax savings account with every payment you receive.
