TaxSoloist is a set of free calculators and plain-English guides for one problem: understanding what you owe, which form you need, and how to file or pay without wading through jargon.
We cover U.S. federal and state taxes: income tax and withholding forms, sales tax, credits and deductions, and payment and filing steps. We started with the self-employed, so 1099 contractors, freelancers, rideshare and delivery drivers, platform sellers and content creators remain a core part of what we write about. Every guide links to the official IRS or state source it is based on.
What you’ll find here
Start with the calculators — self-employment tax and quarterly estimated payments today, with more being added over time — for the numbers you need right now. Around them sits a growing set of plain-English guides: tax forms explained line by line, what you can actually write off and who qualifies for it, state-by-state rules, platform-specific breakdowns for gig work, and timely coverage whenever a rule actually changes — a new IRS instruction, a shifted deduction — explained as what changed and what to do about it, not just that it happened.
What we don’t do
We don’t file forms on your behalf, we don’t charge you for anything the IRS or SSA gives out for free, and we don’t claim to be your accountant. Every calculator and guide here is general information based on published IRS rules — it’s a starting point for understanding your numbers, not a replacement for a tax professional when your situation gets complicated.
