On Saturday, the IRS announced that it will begin accepting tax returns with Form 8863 for education credits on Thursday, Feb. 14.
Also, beginning today, the IRS is beginning to process returns that include Form 4562 for depreciation and amortization.
With this, most taxpayers can file their federal income tax returns for the 2013 tax season. Most of the remaining forms will be available for processing by the first week in March.
Any of the remaining forms affected by the January legislation will be accepted during the first week of March.
Originally, the IRS said the "vast majority" of taxpayers could start filing Jan. 30, but millions couldn't because the IRS said it needed more time to adjust its return-processing apparatus to reflect a law enacted Jan. 2. That new law included many provisions affecting returns for 2012.
Earned Income Tax Credit: File even if you don't ow taxes
One out of five eligible workers and families miss out on the Earned Income Tax Credit, or EITC, which is designed to help the working poor, because they don't file for taxes when they don't owe. This is a "refundable" credit, meaning people can get refunds even if they don't owe any taxes.
