SB1377

Modifies tax deficiency refund provisions in Missouri, allowing erroneous tax deficiency refunds regardless of protest filing.

Missouri SB1377 modifies tax deficiency refund provisions by allowing taxpayers who have paid erroneous tax deficiencies, including interest, additions to tax, or penalties, to receive a refund regardless of whether they filed a timely protest. The bill repeals and replaces section 143.621 of the Revised Statutes of Missouri, extending the notice of deficiency period to 60 days for in-state taxpayers and 150 days for those outside the United States.
