IANAL, but I believe you are wrong going by the very same link.
Connecticut was your domicile (permanent legal residence) for the entire 2016 taxable year; or • You maintained a permanent place of abode in Connecticut during the entire 2016 taxable year and spent a total of more than 183 days in Connecticut during the 2016 taxable year.
Further:
Who Must File Form CT-1040NR/PY You must fi le Form CT-1040NR/PY, Connecticut Nonresident and Part-Year Resident Income Tax Return, if you were a nonresident or part-year resident of Connecticut in 2016 and any of the following is true for the 2016 taxable year: You had Connecticut income tax withheld; • You made estimated tax payments to Connecticut or made a payment with Form CT-1040 EXT, Application for Extension of Time to File Connecticut Income Tax Return for Individuals; General Information QRCs for websites, DRS publications, telephone numbers, and email addresses referenced on this page. DRS Website 8003829463 DRS Telephone 8602975962 DRS Telephone Page 6 • You were a part-year resident who meets the Gross Income Test or who had a federal alternative minimum tax liability; or • You were a nonresident with Connecticut-sourced income who meets the Gross Income Test or had a federal alternative minimum tax liability. See Connecticut-Sourced Income of a Nonresident, on Page 8. If none of the above apply, do not fi le Form CT-1040NR/PY
And what is a part-year resident?
You are a part-year resident for the 2016 taxable year if you changed your permanent legal residence by moving into or out of Connecticut during the 2016 taxable year. If you are a part-year resident, you may not elect to be treated as a resident individual. If you are a part-year resident and you meet the requirements of Who Must File Form CT-1040NR/PY for the 2016 taxable year, you must fi le Form CT-1040NR/PY.
You are only considered a resident if you spend 183 days or more in the state. I don't see anything else that applies to this particular situation.
IF you are a resident with taxable income, then you must pay CT income taxes. But if you can claim primary residency in Florida, you don't have to. At least that's what I am reading.
