Chicago post office open late for last-minute tax filers

There's still a way to get your federal tax returns in on time in Chicago if you don't quite make it to your local post office before it closes.

A U.S. Postal Service statement says the Cardiss Collins facility downtown will remain open until midnight Monday for last-minute filers. There will be collections at the street level. A second floor retail area will be open inside for those who want certified mail and other services. 

No other Chicago postal stations will offer extended hours on April 15. 

Post office officials say a common problem is that people don't use the proper postage when mailing in their returns or don't address it to the right IRS office.
