Yes - However, you may feel more comfortable with actually filing a CT non-resident state return for 2017 and report ($0) for the income. You must mail in this nonresident state income tax return (cannot efile a $0 state return) and include your state W-2 information. You will want to include an explanatory statement (a .pdf attachment) with your return stating your situation (that your employer incorrectly allocated a portion of your bonus income to CT and was not willing to correct the error).
This way you have proof that you actually did submit a CT nonresident state income tax return (mail certified) so as to avoid the CT DoR saying you had CT income but did not file.
