Time limit to file a claim for tax refund modified.

HF 3697 modifies Minnesota's tax refund filing deadline, shortening the standard window from 3.5 years to 2 years for most taxpayers. The bill requires claims for overpaid state taxes to be filed within two years of when the tax, penalties, or interest was paid, instead of the previous 3.5-year period. This change directly affects individual and business taxpayers seeking refunds for overpaid Minnesota state taxes, limiting the refund amount to taxes paid within the two-year period preceding the claim. The amendment applies to all refund claims filed on or after the bill's effective date.
