How Mississippi sales tax is worked out
Mississippi: 5% on the sales price after the trade-in. The state's rule counts additions to the selling price, so the document fee and other charges are included here (confirm with the DOR); a service contract is not taxed. The buyer pays ad valorem tax, privilege tax and registration at the county tax collector. Title fee starts at $9. The Mississippi Motor Vehicle Commission caps the document fee at $425 and requires its notice beside the fee.
Required wording beside the dealer fee
Mississippi requires this wording where the dealer fee appears. The Buyer's Order prints it.
A DOCUMENT/SERVICE FEE IS NOT AN OFFICIAL FEE AND IS NOT REQUIRED BY LAW, HOWEVER, IT MAY BE CHARGED TO A BUYER/LESSEE FOR THE PREPARATION, HANDLING AND PROCESSING OF DOCUMENTS AND THE PERFORMANCE OF SERVICES RELATED TO THE SALE OR LEASE OF A MOTOR VEHICLE AND MAY INCLUDE DEALER PROFIT. THIS NOTICE IS REQUIRED BY REGULATION OF THE MISSISSIPPI MOTOR VEHICLE COMMISSION.
