35 Miss. Code. R. 4-01-01-402
The Commissioner requires any entity wishing to take advantage of the sales tax exemptions provided for under Miss. Code Ann. Sections 57-10-1 et seq., 57-61-1 et. seq. and 57-71-1 et seq. to obtain a direct pay permit. The direct pay permit holder must present the permit to its vendors in order to purchase tangible personal property and services exempt from tax. This direct pay permit is applicable only for purchases made for the specified project. The direct pay permit holder must accrue and pay the applicable sales and use tax on any purchases that are not made with or reimbursed with bond proceeds. The exemption does not apply to any contractor's tax levied under Miss. Code Ann. Section 27-65-21 or vehicles tagged for highway use. The direct pay permit for this exemption will stand rescinded when the bond money is depleted and tax will once again be due to the vendor if the applicant is not a qualified industry.
