A pronouncement by the New York State Department of Taxation and Finance explains a regulation amendment raising the MTA surcharge rate under Article 9-A from 28.3% to 28.6% for tax years beginning in 2018. Technical Memorandum, "MTA Surcharge Rate and Deriving Receipts Thresholds for 2018," TSB-M-17(4)C (N.Y.S. Dep't of Taxation & Fin., Dec. 4, 2017). Under the Tax Law, the Department must annually set the surcharge rate to ensure that receipts from the surcharge will meet, but not exceed, the projected surcharge revenues for the State's current fiscal year that began last April 1. The Department has not, however, adjusted the annual threshold for deriving receipts from activities in the Metropolitan Commuter Transportation District (generally at $1 million or more of receipts from activities within the district) that subjects a corporation to the surcharge.
