Trade or business income apportionment provision and foreign sales factors in the apportionment percentage of certain taxpayers requirement provision

This bill updates Minnesota's tax rules for businesses that sell goods across state lines and operate foreign subsidiaries. Starting in the 2026 tax year, it changes how certain companies calculate their state tax liability by gradually shifting the weight of their sales, property, and payroll factors toward 100% sales and 0% for property and payroll. Additionally, it requires specific manufacturers with foreign income to include that income in their sales calculations when determining their tax share. The law applies to businesses required to apportion income under current state statutes and does not affect those already using alternative methods.
