In the US, there are different tax rules and laws in each individual state, as well as at a federal level.
Depending on where you live, you may be required to file a state tax return. In this article we will outline what you need to know about each state’s tax filing requirement.
So, let’s start with the easy part.
States with no income tax
Nine US states don’t impose any income tax on income.
This means that, if you live and work in one of the states below, only federal tax will be deducted from your income. You will not have to pay any state income tax.
- Alaska
- Florida
- Nevada
- New Hampshire (taxes only investment income, not earned income)
- South Dakota
- Tennessee (taxes only investment income, not earned income)
- Texas
- Washington
- Wyoming
While the states above don’t deduct individual income tax, they may still deduct taxes such as corporate tax, among others.
What to do if you have a state filing requirement
Meanwhile, if you work or invest in a state that has an income tax, it’s likely that you must file a state tax return. This is a separate document to your federal tax return. States are independent from one another in their taxing authority, and all state tax forms differ in some respects. In other words, the type of document you must file – as well as the deadline to file – differs from state-to-state. You can find a full list of everything you need to know below.
