Filing Requirements

Determination as to who must file an Oregon state income tax return depends largely on where you live and where they income you earn comes from.

Resident

If you lived in Oregon for 200 or more days during a calendar year or you otherwise maintain a home in Oregon, you are considered a resident of Oregon for that calendar year and you must pay Oregon state income tax on all income earned during that calendar year from all sources, even those based outside of Oregon.

If you are a resident of Oregon based on the above requirement, you must file an Oregon state income tax return if your gross income is more than the amount noted in the table below:

Filing status is:	Age:	Gross income is more than:

Due Date

Your Oregon state income tax return must be filed by April 15 each year, or if April 15 falls on a weekend or holiday, the first non-holiday business day after April 15.  If you need additional time to file your state income tax return, you can file an automatic six-month extension so long as you request it before April 15.

Even if you receive an extension, remember that the extension only applies to the filing date of your return.  If you owe a tax liability, you must still make an estimated payment of tax owed by the original April 15 filing date.  Oregon will charge a penalty and interest on any unpaid tax liability.
