35 Miss. Code R. § 4-04-09-101
Items permanently attached to and becoming a component part of the manufactured home at the time of the sale are included in the purchase price that is taxable at 3%. Examples would be a built-in dishwasher and central heating and air conditioning. Appliances sold and shipped by the manufacturer with the home and included in the overall price of the home from the manufacturer are also considered part of the manufactured home taxable at the reduced rate of 3%. Other furniture and freestanding appliances purchased and resold by the manufactured home dealer are taxable at the 7% rate of tax. The sales price of the additional freestanding furniture and appliances should be separately stated from the sales price of the manufactured home. Likewise, the 7% sales tax should also be separately stated from the 3% sales tax.
