The start of the 2011 filing season will begin in January for the majority of taxpayers. However, the last and late changes in the law mean that the IRS will need to reprogram its processing systems for three provisions that were extended in the Tax Relief, Unemployment Insurance Re-authorization and Job Creation Act of 2010 that became law on Dec. 17. 2010.

People claiming any of these three items – involving the state and local sales tax deduction, higher education tuition and fees deduction and educator expenses deduction as well as those taxpayers who itemize deductions on Form 1040 Schedule A — will need to wait to file their tax returns until tax processing systems are ready, which the IRS estimates will be in mid- to late February.

“The majority of taxpayers will be able to fill out their tax returns and file them as they normally do,” said IRS Commissioner Doug Shulman. “We will do everything we can to minimize the impact of recent tax law changes on other taxpayers. The IRS has worked through the holidays and into the New Year to get our systems reprogrammed and ensure taxpayers have a smooth tax season.”
