How much should an Arizona 1099 contractor set aside for taxes?↓
Arizona freelancers can typically set aside 28–35% of net income thanks to the state's low 2.5% flat income tax rate. This covers federal self-employment tax (15.3%), federal income tax at your marginal rate, and Arizona's 2.5% state tax. The low state rate is a significant advantage compared to states like California (up to 13.3%) or New York (up to 10.9%).
When did Arizona switch to a flat income tax rate?↓
Arizona implemented its flat 2.5% income tax rate starting with the 2023 tax year. Previously, Arizona had a multi-bracket system with rates ranging from 2.59% to 4.5%. The flat rate replaced all prior brackets. This change benefited higher-income earners the most while simplifying tax calculation for everyone.
How do I pay Arizona estimated taxes as a freelancer?↓
Arizona estimated tax payments are made using Form 140ES (Individual Estimated Income Tax Payment). Payments are due on April 15, June 15, September 15, and January 15.
