Connecticut has passed a bill that provides tax relief for 2020 only for employees working remotely who would have potentially had their wages taxed by two states (H.B. 6516) The bill provides particular relief to Connecticut residents who are required to pay income taxes for the 2020 tax year to other states that use some version of the "convenience of the employer" rule, for example, providing relief to Connecticut residents who telecommuted to Massachusetts and New York-based employers.

Currently six states formally impose some version of the convenience of the employer rule: Arkansas, New York, Connecticut,1 Delaware, Nebraska and Pennsylvania. Additionally, in response to the COVID-19 pandemic, Massachusetts published an emergency regulation declaring that income earned by a nonresident working outside of Massachusetts would be considered Massachusetts source income if, prior to the COVID19 state of emergency, the employee performed such services in Massachusetts.

Generally, states using the convenience of the employer rule treat wages paid to nonresident telecommuting employees as wages sourced to that state, if the employee telecommutes for his or her own personal convenience. Formulations may differ slightly, but Nebraska imposes a fairly standard version of the convenience of the employer rule that may be considered a representative example. Generally, Nebraska may only tax nonresidents if they perform services in Nebraska. However, "if the nonresident's service is performed without Nebraska for his or her convenience, but the service is directly related to a business, trade, or profession carried on within Nebraska and, except for the nonresident's convenience, the service could have been performed within Nebraska, the compensation for such services shall be Nebraska source income."2 In other words, Nebraska-and other convenience of the employer states-may tax a nonresident for work conducted outside of the state, if such work was conducted outside the state for the employee's convenience.

Specific Provisions of the Connecticut Bill

The bill provides Connecticut residents with a full credit for income taxes paid to another state, if the Connecticut resident worked in Connecticut but paid income taxes to another state due to that other state's convenience of the employer rule. This relief was not provided under prior Connecticut law.

Specifically, the bill provides that for the taxable year commencing on January 1, 2020, "any resident who paid income tax to any other state that uses a convenience of the employer rule shall be allowed a credit against such resident's Connecticut income tax, for the tax paid to such other state on income earned by such resident while working remotely" from Connecticut.

The bill also provides that a full credit will be allowed in the 2020 tax year for "any resident who paid income tax to any other state that has enacted a law or rule requiring a nonresident employee to pay nonresident income tax to such other state on income earned while such nonresident employee was working remotely from this state due to COVID-19 if, immediately prior to March 11, 2020, such nonresident employee was performing such work within such other state.." This provision of the bill appears to be a clear response to the emergency regulation adopted by Massachusetts.

Finally, the bill also establishes that Connecticut will not consider the activities of any employees who worked remotely in Connecticut due to COVID-19 during the 2020 tax year in determining whether an employer has nexus with Connecticut (and thus may be subject to entity-level state taxation).


It should be noted that the scope of relief provided by the bill is limited to 2020 only: the Connecticut income tax credits are only allowed for taxes paid to another state that imposes a convenience of the employer rule (or something similar) for the 2020 tax year. This was emphasized in a bulletin issued by the Commissioner of the Connecticut Department of Revenue.3 The bill thus represents a temporary measure intended to provide relief to Connecticut residents who otherwise could face a burden of double taxation during the COVID-19 pandemic in 2020. Although the relief provided by the bill is temporary, however, it is not insignificant-the Connecticut Office of Fiscal Analysis estimated that if the credit did not apply, Connecticut residents would owe approximately $300 million more in personal income tax payments for the 2020 tax year.

The convenience of the employer doctrine and the rights of states to impose taxes on nonresident telecommuters will continue to be an issue moving forward. New Hampshire filed suit in the U.S. Supreme Court, challenging the tax imposed by Massachusetts on nonresidents who prior to the COVID-19 pandemic had performed such services in Massachusetts. As the Supreme Court determines whether to hear the case, several states, including Connecticut, have filed an amicus brief supporting New Hampshire's position. In the amicus brief, the amici summarize the persistent importance of the issue: "to avoid problems of double taxation, many States that levy income taxes grant credits in whole or in part to their residents for taxes paid to other States. Whether Massachusetts or other States can levy taxes directly on the income of nonresidents working from home affects billions of dollars in state tax revenue."4
