I'm Jordan Keller, and I built SelfEmploymentTaxEstimator.com as a free educational tool for freelancers, independent contractors, gig workers, and anyone with self-employment income. I'm a self-employed consultant, and I went through the exact same experience most freelancers face: realizing that taxes work completely differently when no employer is handling withholding for you.
When you transition from traditional employment to self-employment (or start picking up freelance work on the side), the tax landscape changes significantly. You're suddenly responsible for self-employment tax, quarterly estimated payments, and tracking your own deductions. The IRS resources are thorough but dense, and most online calculators either oversimplify the math or bury important details behind a paywall.
I built this site to fill that gap: a free, no-signup, no-paywall calculator that handles the real complexity of self-employment taxes, including combined W-2 and 1099 income, the Social Security wage base offset, the 50% SE tax deduction, and quarterly payment estimates. The guides section provides plain-language educational content explaining the concepts behind the numbers, so you understand what the calculator is doing and why.
This is an educational estimation tool, not a tax preparation service. It does not file taxes, generate official IRS forms, or account for every possible deduction, credit, or individual circumstance. It does not calculate state taxes. The estimates here are a starting point for planning, not a substitute for working with a qualified tax professional.
If your tax situation is complex (business entity structures, depreciation, retirement contributions, multiple state obligations), I encourage you to work with a qualified CPA or enrolled agent who understands self-employment. This calculator helps you build the intuition and ballpark numbers you need to have an informed conversation with that professional.
My name is Jordan Keller. I write under a pen name to keep my personal and professional lives separate, but the experience is real: I run a small consulting business and have dealt with every aspect of self-employment taxes firsthand. Quarterly payments, estimated tax calculations, combined W-2 and 1099 income, the learning curve that comes with managing your own tax responsibilities: I've navigated all of it. I originally built this tool to solve my own problem, and I share it freely because I believe this educational information should be accessible to anyone who needs it.
