MO SB612

Extends the nonresident entertainer and professional athlete income tax allocation program from December 31, 2015 to December 31, 2020, continuing 60% allocation to Missouri Arts Council and 10% each to Missouri Humanities Council, State Library Networking Fund, Public Television Broadcasting Corporation, and Historic Preservation Revolving Fund.

Requires 2% withholding tax on compensation paid to nonresident entertainers and professional athletes when compensation exceeds $300, with quarterly remittance to the Director of Revenue.

Establishes definitions for "nonresident entertainer," "nonresident member of a professional athletic team," and "personal service income" including salaries, wages, bonuses, and strike benefits, but excluding competition prizes from livestock and rodeo events.

Modifies sales tax provisions requiring sellers to be notified by the Department of Revenue before tax modifications take effect; failure to notify relieves sellers of tax liability until notification occurs.

Expands sales tax exemptions to include materials and equipment used by commercial or industrial laundries processing at least 500 pounds of textiles per hour and 60,000 pounds per week.
