Not tax advice
Everything on GigTax — calculators, articles, examples — is general educational information about US self-employment taxes. It is not tax, legal, accounting or financial advice, and it is not a substitute for the IRS instructions that apply to your return.
No professional relationship
GigTax is not a CPA firm or an enrolled-agent practice. Reading this site or using a calculator does not make you a client, and we cannot prepare returns, sign filings or represent you before the IRS.
Estimates only
Calculator output depends entirely on the numbers you enter and on published IRS rates and thresholds current at the time of writing. Rates, mileage amounts, brackets and reporting thresholds change. Your actual liability can differ because of credits, other household income, filing status, state and local rules, or deductions we don’t model.
Verify before you file or pay
Before making a quarterly payment or filing a return, confirm figures against the relevant IRS publication or with a qualified professional. You remain responsible for what you report and for any tax, penalty or interest assessed.
External links and corrections
We link to IRS and other third-party resources for verification and don’t control their content. Spotted an error? Email niamatjaved2@gmail.com with the source and we’ll correct it.
