You file taxes in any state where you are a resident for tax purposes. The term "resident" has a different meaning for tax purposes than it does for other purposes such as in-state tuition or unemployment compensation. Each state has its own definition of a resident.
If you lived in several states during the year, you would file in all of them. If you have very complicated affairs, it is even possible to simultaneously be a resident of two or more states.
You also file in any state where you have what is known as "state source income." For example, if you worked in a state, owned income-producing property in a state, sold property located in a state, owned a business that operated in a state, won money in a casino operated in a state, then you need to file in that state.
Each state can tax all income earned by its residents no matter where in the world it is earned. Each state can also tax state source income from non-residents.
When two states tax the same income, generally the state of residence will allow its residents to claim a whole or partial credit for taxes paid to another state. Sometimes it is the reverse (for example California residents claim a credit on Arizona non-resident taxes for taxes paid to California). Sometimes two states have an agreement to exempt each other's residents from some taxes (for example, Ohio and Kentucky have an agreement not to tax each other's residents on wages only).
Many numbers on your State return are going to be based on your Federal return, so you should probably prepare your Federal return first.
Yes when you have taxable income you would file a federal and state income tax return.
There is no exact date for either the State or Federal Income tax refund to get to you. If you file electronically, they will usually get to you at about the same time but there will not be a significant difference.
Anyone with any income, or even without an income can file. You are required to file Federal taxes if you made more than $1,800. Illinois requires anyone that earns or receives income in the state to file state taxes.
I think you are asking what must you file first. My state requires that you file federal taxes first because information from the federal forms is transferred to the state forms.
yes you do
FEDERAL income tax is governed by FEDERAL law and regulations- same everywhere. Different STATES may have different STATEtaxes.
Your income must be 58000 or less to file your federal income taxes for free. If your income is higher then you cannot file them for free from e-file.
For the state of Arizona it is 4 years, but since it is based on Federal Taxable income, one must complete that first even though Federal statute of limitations is only 3 years to file.
Yes on your federal 1040 income tax return ALL of your gross worldwide income is REPORTED on the only1 federal income tax return that would be ALLOWED to file for the tax year.
If that was their only income, then they probably do not have to file a federal return. But remember both earned and unearned income counts. State tax requirements vary by state. But if they had any income tax withheld, they should file in order to get a refund.
Yes you can still file a 1040 federal income tax return but you would not have any reason to file one.
Yes, as long as you file the extension for your Federal return.
