SALEM – The Oregon Department of Revenue is extending its telephone hours through April 17 to help last-minute tax filers. Because April 15 falls on a Saturday, people have until midnight, April 17 to file.

If you have questions about income taxes and can’t find the answers in the tax booklet or online, customer service representatives are available by phone. The agency’s tax help phone lines will be staffed 7 a.m. to 8 p.m. Monday through Friday through April 17.

Revenue will staff customer service phones from 9 a.m. to 4 p.m. April 15.

The tax help line is (503) 378-4988 (Salem area or outside Oregon), or (800) 356-4222 (toll-free from an Oregon prefix). Because of the high volume of calls the department receives during tax season, people may experience extended wait times or get a busy signal. Tax questions may be e-mailed to (questions.dor@state.or.us). E-mails are usually answered within two business days.
