About SelfEmployLab
Free, IRS-checked tax calculators for US freelancers and 1099 contractors
Seven free calculators for freelancers and 1099 contractors: self-employment tax, quarterly estimated taxes (with the safe-harbor minimum and due dates), how much of each payment to set aside, S corp vs LLC savings, 1099 vs W-2 offers, the hourly rate you need for a target take-home pay, and the home office deduction. Every calculator uses the current IRS figures, shows the math step by step, and works without an account. Any site can embed them for free. There is also a tax guide for each state and a 50-state study of freelancer take-home pay. Built for people who redo this math in a spreadsheet every quarter. Not tax advice: the numbers are checked against IRS publications, but your situation may differ.
