This in-depth guide compares key tax aspects for freelancers in the United Kingdom (UK), Ireland (IE), Australia (AU), New Zealand (NZ), and Canada (CA), focusing on income tax bands, personal allowances, and social contributions.

The Foundation: Personal Allowances and Income Tax Bands
One of the first things to understand is how your personal income is taxed. Most countries offer a 'Personal Allowance' or a similar tax-free threshold, meaning you don't pay income tax on the first portion of your earnings. Beyond this, income tax is typically levied in progressive bands, meaning higher earnings are taxed at higher rates.

These help spread the tax burden throughout the year.
