The Internal Revenue Service reported today it will start the 2013 tax filing season on Jan. 30 instead of the originally-planned Jan. 22 kickoff date.

The late tax law changes made by the U.S. Congress to resolve the "fiscal cliff" crisis resulted in the delay. The Oregon Department of Revenue will start filing the same day.

"The amount of time it takes us to process each return will be the same," said Theresa Schuh, the state Department of Revenue's Personal Income Tax Program manager. "We typically don't receive very many returns in January, so we should catch up quickly."

Taxpayers should wait until they have their W-2s before filing, as filing a return without the form causes delays.
