New York Court Denies Sunoco's Tax Refund Request

In a recent ruling, the Appellate Division of the Supreme Court of the State of New York denied Sunoco, Inc. (R & M) Combined Affiliates' request for a refund of approximately $2.6 million in corporate franchise taxes. This decision affects not only Sunoco but also sets important precedents for how corporations calculate their tax obligations in New York.

The case, officially titled Matter of Sunoco, Inc. (R & M) Combined Affiliates v. Tax Appeals Tribunal of the State of N.Y., was filed under docket number CV-25-0480 on July 23, 2026. The ruling emphasizes the complexities of corporate tax law and the importance of accurately reporting business transactions.

Sunoco, which is primarily engaged in petroleum refining and chemical manufacturing, had sought to amend its tax returns for the years 2007 through 2010. The company argued that it should be able to include certain transactions in its calculation of business receipts, which would lower its tax obligation. However, the Tax Appeals Tribunal and subsequently the Appellate Division found that these transactions did not qualify as business receipts under New York tax law.

The dispute arose from Sunoco's buy/sell transactions, where the company bought oil from a third-party dealer and simultaneously sold the same volume to its customers. Sunoco initially excluded the amounts from the sell side of these transactions when calculating its business allocation percentage (BAP) for tax purposes. After filing amended returns, which included these amounts, the New York Department of Taxation and Finance denied the refund requests.

Sunoco's argument was that including the sell side of the transactions would accurately reflect its business activity. However, the Administrative Law Judge (ALJ) and the Tax Appeals Tribunal determined that these transactions were essentially exchanges of inventory rather than sales. The ALJ concluded that the amounts from the sell side could not be included in Sunoco's BAP calculations.

The court ruled that the Tax Appeals Tribunal's decision was rational and supported by substantial evidence. The opinion stated, "the Tribunal's determination that petitioner had failed to meet its burden of proving entitlement to the claimed refunds is rational and supported by substantial evidence in the record." This ruling confirms the importance of accurately reporting business transactions and adhering to tax regulations.

The impact of this ruling extends beyond Sunoco. Corporations operating in New York must carefully consider how they report their business receipts and understand the implications of their transaction structures on their tax obligations. The court's decision reinforces the notion that tax authorities have discretion in determining what constitutes business receipts and can exclude certain transactions from tax calculations.

Going forward, businesses may need to reassess their tax strategies and ensure compliance with New York tax laws. This ruling may also encourage other companies to closely examine their transaction structures to avoid similar disputes with tax authorities.

As for what’s next, Sunoco has the option to appeal the decision. However, details regarding any potential appeal were not available in the court filing. The outcome of this case could influence future tax disputes involving corporate transactions in New York.
