State revenue officials are busy looking through the returns of 260,000 Minnesotans who might qualify for extra tax rebates.
The Minnesota Department of Revenue has already manually reviewed about 52,000 of the tax filings and plans to finish the rest by June 27.
Between now and then, Minnesotans who qualify will receive an additional refund automatically or be asked for additional information or be told they need to file an amended return.
"We are making progress," said state Revenue Commissioner Myron Frans.
Minnesota revenue officials are scrambling to review individual income taxes that were filed before Gov. Mark Dayton and legislators passed about $444 million in tax relief, including millions in retroactive tax breaks for the 2013 tax year. Legislators approved the retroactive tax relief in the middle of tax season, creating a frantic race by revenue officials to get the changes on the books even as completed tax returns were streaming in.
More than 1.1 million Minnesotans filed their income taxes after the new tax law took effect April 1, which means their filings would have come in under the new laws and would not require manual review.
The tax measure better aligns Minnesota's tax code to federal deductions, and was passed with overwhelming bipartisan support.
Those eligible for retroactive relief include college graduates paying off student loans and Minnesotans receiving tuition assistance from employers. Consumers who lost their home to foreclosure or sold them at a steep loss through a short sale will get some of the largest immediate relief.
