MTC Uniformity Committee to Reevaluate Sourcing Rules

May 12 — The Multistate Tax Commission's draft market sourcing rules are returning to the Uniformity Committee for reexamination of provisions that elicited concerns among practitioners during an Executive Committee meeting.

During a May 12 session, the Executive Committee voted to direct further study and consideration by the Uniformity Committee of proposed regulations that track the MTC's 2014 adoption of legislation shifting from a cost-of-performance (COP) regime to market sourcing under Article IV, Section 17 of the Multistate Tax Compact (incorporating the Uniform Division of Income for Tax Purposes Act (UDITPA)).

The Uniformity Committee had approved and advanced the rules and related regulatory definitions to the Executive Committee during the December 2015 committee meetings.

Practitioners raised issues relating to the Section 1 definition of “receipts,” including its scope and exceptions, which excludes receipts from hedging and lending of cash or security transactions.

Other concerns arose from Hearing Officer Brian Hamer's May 1 report, rejecting some practitioner recommendations and proposing language to incorporate others or clarify regulatory provisions after a March 9 hearing (2016 Weekly State Tax Report 17, 5/6/16).

The Uniformity Committee is now charged with digesting the public commentary and Hamer's report, and reporting back to the Executive Committee during the July meeting.

‘Receipts' Carve-Out

A primary target of the public comments was the regulatory scope of “receipts,” including specific remarks documented and discussed by the Council On State Taxation (COST) and the Financial Institutions State Tax Coalition (FISTC).

Voicing similar concerns regarding the definition's removal of receipts from hedging and lending transactions, Joe Huddleston highlighted how excluding prevalent transactions from the sales factor, but treating themas apportionable income, runs counter to both MTC and constitutional principles.

“Derivatives and hedging markets play a vital role in today's economy, and also businesses engage in various types of lending transactions, including security lending or overall lending,” said Huddleston, an executive director for Ernst & Young LLP’s Indirect Tax group in the National Tax office and former MTC executive director.

“Today's business activities actively engage in products in the regular course of business to manage risk and increase profit.”

Areas of Concern

While acknowledging the complexities and concerns with such transactions, he identified four primary areas of concern relating to an exclusion:

  •  distortion of a taxpayer's corporate income in determining the sales factor, which deviates from the purpose of UDITPA;
  •  inconsistencies with federal treatment of hedging transactions;
  •  inconsistencies with existing state definitions, including recently enacted provisions in Illinois, California, Montana and Florida; and
  •  inconsistencies with the treatment of hedging and lending transactions for financial institution receipts, which may cause differing apportionment formulas for similarly situated taxpayers.


Recognizing the MTC's Section 18 work group, which is addressing potential income distortion from the exclusion of functional receipts from the receipts factor, Huddleston, COST and FISTC suggested that a resolution incorporated in Section 17 may be more appropriate.

Other Observations

Speaking on behalf of the American Bar Association Section of Taxation, Shirley Sicilian responded to Hamer's reasons for rejecting a dispute resolution tool to resolve potential duplicate taxation.

Originally recommended in a March 1 letter, the tax section's proposal suggested nonbinding mediation as a mechanism to address multiple taxation arising from varying apportionment methodologies, all the while respecting states' sovereign authority to adopt individual sourcing regimes (2016 Weekly State Tax Report 16, 3/4/16).

Sicilian observed that “states are nearing the halfway point in the transition” from COP to market-based sourcing, arriving at the “apex” for potential multiple taxation. While Hamer encouraged uniform adoption of sourcing rules among states, Sicilian noted that significant time will pass before that could happen – notwithstanding whether people consider it a good or bad solution. And mediation facilitates the Compact's objective of avoiding duplicate taxation and aligns with the MTC’s current internal program to assist in resolving controversies.

Michael Fatale, deputy general counsel with the Massachusetts Department of Revenue, also raised issue with Hamer's suggested removal of language that requires a taxpayer to determine a modified approximation method on a prospective basis improves accuracy. Noting that another provision imposes such a burden on states, Fatale urged inclusion of the language to foster an “even-handed approach.”

Other Uniformity Projects

Helen Hecht, MTC general counsel,, and Wood Miller, chair of the Uniformity Committee, updated the group on other uniformity projects:

  •  The proposed statute on sales and use tax nexus, otherwise known as the “Engaging in Business” model, garnered support from a majority of affected states in a Bylaw 7 survey and will be placed on the MTC's July annual meeting agenda (2016 Weekly State Tax Report 23, 5/6/16).
  •  The model sales and use tax notice and reporting statute remains tabled, pending a resolution in DMA v. Brohl, 814 F.3d 1129(2016). As the 10th Circuit found the Colorado reporting statute was not unconstitutional, practitioners are awaiting DMA to file a potential petition for certiorari with the U.S. Supreme Court.
  •   A partnership informational project, initiated to address the state impact of a new federal partnership audit regime enacted as part of the Bipartisan Budget Act of 2015, has held and is likely to hold additional informational sessions to determine the issues that may need to be taken up. Several states have volunteered to participate in the work group, including Alabama, Montana, New Hampshire, North Carolina, Oregon and Texas.
