Connecticut’s Tax Gambit: Connecticut Considers Convenient Position on “Convenience of the Employer” Rule

The Connecticut House of Representatives is considering multiple proposals that would permit Connecticut residents and part-year residents to take creditsct-150x150 for tax paid to other states while working from Connecticut during the pandemic.  Connecticut law currently allows credits for tax paid to another state only if: (1) the individual was physically located in such other state while working; or (2) the individual is a resident of a state that applies the “convenience of the employer” sourcing rule.  Two bills have been introduced, both of which would expand the allowable credits only for Connecticut residents and part-year residents for the tax year beginning January 1, 2020.  H.B. 6183; S.B. 873.

The bills have been proposed as Connecticut legislators decide how to use a projected budget surplus for the fiscal year ending June 30, 2021.  The unexpected surplus may be due partly to Connecticut’s unique personal income tax sourcing regime, which under the circumstances of the pandemic operates to produce a windfall.  Connecticut employs a standard residency-source personal income tax regime that permits residents to take credits for tax paid to another state only if the resident physically worked from that state.  However, Connecticut alters the sourcing rule for residents of states that apply the “convenience of the employer” sourcing rule.  Under this rule, an individual’s work from outside of her employer’s state is sourced to the employer’s location unless the employee’s work location is for the employer’s convenience.  Connecticut applies this rule only to individuals that are residents of a state—like neighboring New York—that also applies the rule.  Conn. Gen. Stat. § 12-711(b)(2)(C).  Thus, while work from home continues, Connecticut law: (a) taxes New York residents working for Connecticut employers; but (b) denies credits to Connecticut residents working for New York employers.

The legislation would alter these rules to permit credits to Connecticut residents, but the ultimate impact of doing so is tied to the outcome of New Hampshire’s pending request in the U.S. Supreme Court.  New Hampshire v. Commonwealth of Massachusetts, Case No. 22O154 (Dkt. Oct. 23, 2020).  New Hampshire requests that the Court invalidate a Massachusetts regulation with similar effect to the convenience of the employer rule.  The Connecticut legislation would provide credits for tax paid to states like New York and Massachusetts only if such states can continue to source employees’ working days to their employer’s locations.  If the U.S. Supreme Court accepts the case and grants New Hampshire relief, the Court may invalidate the convenience of the employer sourcing rule.  That outcome would both eliminate the need to expand Connecticut’s credit regime and preclude Connecticut from taxing nonresidents working outside the state for Connecticut employers.  However, if the Court denies New Hampshire relief, Connecticut’s legislation would allow it to continue taxing New York residents while providing credits to Connecticut residents.
