UNDATED -- Tax season is officially underway.
Today marks the beginning of tax season, when most Americans can submit their returns to Uncle Sam.
The I-R-S had originally planned to kick things off on January 22, but the fiscal cliff debate forced the agency to push the official start date back eight days.
Certain people will still need to wait.
Tax returns claiming the American Opportunity Tax Credit or the Lifetime Learning Credit, two popular education credits, won't be processed until mid-February.
This means the roughly three million people who typically file returns claiming these credits before mid-February will likely have to wait longer for refunds this year.
Other filers with more complex returns, will need to wait until late February or March for their returns to be processed.
The full list of forms being accepted in late February or March can be found on the I-R-S website.
