The Multistate Tax Commission (or MTC) is a United States intergovernmental state tax agency[1] created by the Multistate Tax Compact in 1967.[2] As of 2011, 47 states are members of the Commission in some capacity.[3] Commission members, acting together, attempt to promote uniformity in state tax laws. Its actions do not have the force of law, and member states may opt not to follow its recommendations.

States require purchasers of goods who claim exemption from sales tax to provide certification to the seller of such exemption. The Commission has developed a Uniform Sales and Use Tax Exemption Certificate used by most states.

The Multistate Tax Compact[4] provides that the MTC may conduct audits of taxpayers on behalf of those states specifically authorizing such action. The Compact also provides definitions of terms that may be used by states in writing their tax laws.

National Nexus Program[edit]

The National Nexus Program was created by the Commission in 1990 to facilitate nexus laws for companies engaged in interstate commerce. [5] One of its activities is a multistate voluntary disclosure program, which allows taxpayers with prior year liabilities to anonymously disclose those liabilities to program member States in exchange for the States limiting the number of years that back taxes are due.[6]
