@rjs Do you have a reference? The last list I saw only had New York , Pennsylvania, Nebraska, Delaware and Arkansas as directly taxing telecommuters.
This references says "Connecticut applies it (the CT convenience of the employer rule) only if the taxpayer’s resident state applies a similar rule for work performed for a Connecticut employer"...."Connecticut applies the rule to nonresident employees of a Connecticut employer who work from a remote location and reside in one of the five states listed above".

This 2nd reference says "If a nonresident of Connecticut works in Connecticut and in another state, the employer should withhold Connecticut income tax on that portion of the employee's wages related to services performed in Connecticut".
