The Internal Revenue Service is now processing five tax forms affected by legislation involving the Alternative Minimum Tax (AMT).

On Monday, IRS systems began to accept and process returns that include the five affected forms. After several days of processing, the IRS has confirmed all systems are working properly.

In late December, the IRS announced it would delay processing of several tax forms. For the vast majority of taxpayers, the filing season this year began on time. But for any taxpayer whose return included any of the five affected forms, filing opened on Feb. 11.

Taxpayers who use the five forms can now file their tax returns as normal.

The affected forms are:

Form 8863, Education Credits

Form 5695, Residential Energy Credits

Schedule 2, Form 1040A, Child and Dependent Care Expenses for Form 1040A Filers

Form 8396, Mortgage Interest Credit

Form 8859, District of Columbia First-Time Homebuyer Credit

Approximately 13.5 million taxpayers are expected to use these forms this year. Altogether, the IRS expects to receive nearly 140 million individual tax return submissions this year.

The IRS has worked closely with the software industry and tax practitioners during the reprogramming process to minimize disruptions for taxpayers and the tax community.
