The Multistate Tax Compact (MTC) is a cooperative agreement created in 1967 among certain U.S. states to coordinate and simplify the complex tax obligations faced by businesses operating across multiple states. By establishing uniform guidelines on income sourcing, allocation, and dispute resolution, the MTC reduces the risk of double taxation and conflicting state tax requirements.
Background and History of the MTC
In the United States, individual states have the sovereign authority to impose taxes within their jurisdiction, including income and franchise taxes. For businesses with operations spanning several states, this leads to challenges such as potentially being taxed multiple times on the same income and navigating differing state tax rules. To address these issues, a group of states formed the Multistate Tax Compact in 1967 to harmonize tax administration and ease the burden on taxpayers.
Currently, about 20 states plus the District of Columbia are members of the MTC. Joining is voluntary, and states choose whether to participate. Member states agree to use standard definitions, filing forms, and procedures that make tax compliance more predictable and fairer for multistate businesses.
How Does the Multistate Tax Compact Work?
The MTC provides a framework for member states to:
- Use uniform rules for determining how much income is taxable by each state, including agreed-upon methods for allocation and apportionment of income.
- Administer tax audits more efficiently by coordinating among states to minimize duplicative examinations.
- Exchange tax information confidentially to ensure compliance while protecting taxpayer data.
- Resolve disputes through a formal, often arbitration-based process involving the Multistate Tax Commission before matters escalate to litigation.
For example, a company that earns income in three MTC member states will apply the compact’s uniform rules to calculate the taxable income attributable to each state. If a disagreement arises, the MTC’s dispute resolution process provides a structured approach to settle the issue without costly court battles.
Real-World Examples
Consider an e-commerce company selling products in various states. Without the MTC, it would navigate different tax rules for each state, increasing complexity and risk of overpayment. With member states adhering to the MTC, the company benefits from consistent rules, simplified reporting, and fairer taxation.
Another example is a trucking firm operating interstate routes. The MTC allows member states to agree on income apportionment so that the company is not subject to redundant or unfair taxation by multiple states along its routes.
Who Does the MTC Affect?
The MTC primarily impacts:
- Businesses with multistate operations, particularly those with taxable income or business activity in several member states.
- State tax agencies in member states that adopt the compact to standardize and streamline their tax systems.
Individual taxpayers are typically not affected by the MTC since it focuses on corporate income and franchise taxes.
Tips for Businesses Operating in Member States
- Verify if the states where your business operates are members of the MTC by visiting the official MTC website.
- Understand the uniform rules for income sourcing and apportionment to properly allocate your taxable income.
- Maintain detailed records of income and business activity by state to comply with MTC requirements.
- Use the compact’s dispute resolution procedures to resolve tax conflicts efficiently before pursuing litigation.
Common Misconceptions
- The MTC is not federal law but a state-level agreement among member states.
- Not all states participate; many operate independent tax systems outside the compact.
- While the MTC reduces tax conflicts, it does not eliminate all multistate tax challenges because states retain sovereignty over their tax systems.
Frequently Asked Questions
Is participation in the MTC mandatory for businesses?

Can states withdraw from the MTC?
Yes, since the compact is voluntary, states can join or leave at their discretion.
Does the MTC cover all state taxes?
Primarily, it covers corporate income and franchise taxes, but not sales taxes or other state levies.
