MO HB1801

Creates the "Facilitating Business Rapid Response to State Declared Disasters Act" (sections 190.270-190.285) to exempt out-of-state businesses and employees from Missouri registration, income tax, and withholding requirements during declared disaster periods.

Defines "disaster period" as beginning ten days before a governor's emergency proclamation or federal disaster declaration and extending 60 calendar days after the declared period ends, with potential extension by the governor.

Out-of-state businesses responding to disasters must notify the secretary of state within ten days of entering Missouri, providing name, domicile, business address, federal employer ID, entry date, and contact information.

Exempts out-of-state businesses and employees from income tax withholding, state registration, and use tax on temporary equipment during the disaster period; exemptions end upon conclusion of the disaster period.

Excludes out-of-state disaster-response businesses and employees from existing tax requirements in sections 143.041, 143.071, 143.191, 144.610, and transient employer provisions in sections 285.230-285.234.
