State Income Tax Returns vary from state to state. Some states do not have income taxes at all, while some are more automated than others.
Below is a state income tax navigation chart that allows you to easily pick the right route to either:
State Income Tax Deadlines
Most states have the April 15, 2021 due date for 2020 tax returns, just like the IRS. Some states the deadline is May 1, 2021. However, since most states can only be eFiled together with an IRS return - this is IRS/State policy, not eFile.com - consequently all your state income tax returns should be prepared and e-Filed by that same April 15 date.

When to File a State Resident Return?
Generally, if the state you resided in during a tax year, you will need to file a tax return. If you were a part-year resident of such a state you will need to file one or more part-year resident return(s): if
- You moved from one state to another state - file a part-year resident tax return for both states- OR
- You lived in multiple states - file a part-year resident return for each state
You generally need to file a nonresident tax return for each state in which you worked but did not reside. For example, if you lived in one state and worked in another, you will usually need to file a resident return for the state in which you lived and a nonresident return for the state in which you worked.
Here are other situations where you may need to file a nonresident state return:
- You earned income in a state that is not your resident state.
- Your employer incorrectly withheld taxes for a state that is not your resident state.
- You had gambling winnings in a state that is not your resident state.
- You owned rental property in a state that is not your resident state.
- You are a partner in a partnership, or a shareholder in an S-Corporation, that is based in a state that is not your resident state.
- You received income from an estate or trust that has interest in a state that is not your resident state.
You do not generally have to file a return for the state where your employer is located unless you also work there. What matters is where you earned the income, not where your employer is based.
