Federal extensions are allowed, but the extension must be filed with the city by the original due date of the return. There is one exception. If the taxpayer is delinquent in filing city taxes, the extension is disallowed.
If an extension is granted, only the time to file the return is extended. Taxes are due on or before April 15th or, if it falls on a weekend, the first business day after April 15th. Statutory interest will be charged on payments made after the original due date.
W-2 & W-3 filing:
The Oregon income tax office now allows employers to file their W-2's on diskette. The city requires the same information and format that is required by the federal government. Please use OREG as the local entity code.
We ask that you utilize your client's pre-printed returns as it makes processing at our end more accurate and efficient. Forms are also located on our web page. If you use a generic return, please make sure the filing year of the return, taxpayers' names, social security numbers or alternate ID's, address changes and dates moved in or out are on the return. Returns for part-year residents should not be pro-rated according to the percentage of the year they lived in Oregon. Refer to (12) Other Frequent Questions of the General Instructions page for directions on the correct preparation method. Please remember Oregon city income tax returns are due April 15th or, if it falls on a weekend, the first business day after April 15th. There is a $25.00 late filing fee and penalty and interest charges are 2% per month. If credit is taken for tax paid to another city, you must include a copy of that city's return.
NOTE: To assist in processing returns, please use minimal staples and one-sided copies.
