Besides taxes on gaming…

The tax on net gaming receipts is 13% on the first $150,000,000 and 20% on everything over that.

Each casino licensee shall be subject to the same income, property, sales, gross receipts, use, employment, and other taxation as any for-profit business located in the county and city or town  in which the casino is located, except that no sales or gross receipts tax shall apply to casino gaming receipts or net casino gaming receipts.
