ST. PAUL, Minn. (AP) — Gov. Mark Dayton has signed a bill providing hundreds of thousands of Minnesota taxpayers with extra deductions and exemptions they can claim on this year's tax forms.

Dayton signed the $434 million relief package Friday, soon after both the House and Senate approved it by lopsided margins.

In a statement, Dayton says the tax cuts will put "more money in the pockets of Minnesota families and businesses" and "make taxes simpler for Minnesotans."

The Minnesota Department of Revenue is working with tax preparers and online tax preparation services to update tax filing software for the estimated 1.4 million Minnesotans who have not yet filed their taxes.

For Minnesotans who have already filed their taxes, the department will review each tax return and determine whether adjustments and refunds can be made automatically. The department will contact any taxpayer who needs to file an amended return to receive the new tax benefits.
