Data sources

The rates and standards used in each calculator are based on the following official sources. Rates may change each year and are updated to the latest values when they do.

A note on accuracy

All FreelancerTax results are reference estimates based on your inputs and published formulas. In particular, the income tax / refund calculation does not reflect tax credits or additional income deductions, so it may differ from your actual tax. Actual figures vary with the expense-recognition method (books vs. expense rates), dependents, other combined income, and tax credits, so confirm the final figure with an official authority or a tax professional.
