A hundred years ago it was rare for a person to travel more than 30 miles from where they were born. In the 21st century, we have become a mobile, multi-location society. Today I have clients that work in as many as 5 different states during one year and often have income tax reporting requirements for each state where they work. Then there are my clients who do not even live in the US permanently, but work for clients in various state over the internet.
I am a Certified Public Accountant and Chartered Global Management Accountant and I wrote this guide to help you navigate what are the tax reporting requirements to the various states where you may work? Although there may be similarities between income tax requirements between states, the fact is no two states have the exact same income tax structure and laws.
