Illinois final local Retail Occupation Tax sourcing rules

Multistate tax alert | October 1, 2014

​In this tax alert, we provide a brief overview of the Illinois Supreme Court's decision in in Hartney Fuel Oil Co. v. Hamer and then summarize the final local ROT sourcing rules.

Retail Occupation Tax sourcing rules

In late June 2014 the Illinois Department of Revenue (“DOR”) submitted final local Retail Occupation Tax (“ROT”) sourcing rules to the Secretary of State for publication in response to the Illinois Supreme Court’s decision in Hartney Fuel Oil Co. v. Hamer, 2013 IL 115130 (Nov. 21, 2013).1 The sourcing rules provide guidance for determining which local ROT applies to multi-jurisdictional retailers.

In Hartney the Illinois Supreme Court invalidated the DOR’s prior local ROT sourcing rules.2 The court found fault with two aspects of the rules. First, the rules did not “amply prescribe the fact-intensive inquiry contemplated by” previous case law.3 Second, the rules “impermissibly constrict[ed] the scope of” the statute by “allowing for only one potentially minor step in the business of selling to conclusively govern tax situs.”4

The final sourcing rules (submitted to the Illinois Secretary of State on Jun. 25, 2014) are available on the DOR’s website at:
Hartney Fuel Oil Co. v. Hamer, 2013 IL 115130 at ¶ 61-67 (Nov. 21, 2013).
Id., at ¶ 61.
