About

Bracket & Basis is an educational project for U.S. employees, freelancers and sole proprietors who want to understand a federal tax estimate before preparing a return. We explain the connection between ordinary income tax, self-employment tax and payments made during the year. Our worksheets show formulas and exclusions so that a number has context.

The site is not the IRS, a tax preparation service or a professional adviser. No licensed tax professional has reviewed these pages. Content is prepared with AI assistance and checked against the official sources linked on each page; that is a source check, not an individual tax opinion. We do not promise refunds, approve deductions or recommend an entity election based on a calculator result.

The examples use invented scenarios labeled illustrative. They are not customer cases or statements of market prices. Federal rules are the focus; state, local, international and specialized business issues need separate guidance. Use our checklists to organize questions and records, then use current IRS instructions or qualified professional help to resolve your own facts. Advertising and paid services are not active in this local implementation. The operator has not yet supplied a public contact channel.
