Bought first home in another state while renting and working in another state ( bought in New York while renting in Connecticut)

[kushanperera]

I bought a house with my father in New York City while I live and work in Hartford Connecticut and I'm not sure where I need to file taxes as considering my primary residence. I appreciate your advice!

• Last year I filed my taxes in Connecticut as a part-year resident since I moved to Connecticut in June for work
• Bought in the house in December 2019
• Work full-time in Connecticut 
• I do not own a car but still, I got my New York drivers ID
• No rental income from New York home since my father and brothers live there
• There is around 150 miles from work/my apartment to home I purchased with my father

It seems that you are a Connecticut full year resident for 2019.  moving forward  if you use the New York apartment as an abode (place where you live), you would have to pay both New York and Connecticut if you keep your CT apartment and reside there more than 183.  Just because you purchased the apartment in New York, if it is not your living quarters (visits to your family are fine) you do not establish New York domicile so you would not have to file New York state tax as resident.

this is really useful and I found below in the New York state site. 

If your domicile is New York but you meet all three of the conditions in either Group A or Group B, you are not a New York State resident.

Group A

1. You did not maintain any permanent place of abode in New York State during the tax year; and
2. You maintained a permanent place of abode outside New York State during the entire tax year; and
3. You spent 30 days or less (a part of a day is a day for this purpose) in New York State during the tax year.

Group B

1. You were in a foreign country for at least 450 days during any period of 548 consecutive days; and
2. You, your spouse (unless legally separated), and minor children spent 90 days or less in New York State during this 548-day period; and
3. During the nonresident portion of the tax year in which the 548-day period begins, and during the nonresident portion of the tax year in which the 548-day period ends, you were present in New York State for no more than the number of days which bears the same ratio to 90 as the number of days in such portion of the tax year bears to 548. The following formula illustrates this condition

The question is of DOMICILE= do you intend for the house you purchased in New York to be your home- the place you go back to after absences?  If so, you can establish New York as your domicile and use the above exception so you do not have to file the New York state tax return.  

A person can only have one DOMICILE, so if this is the case, because of the number of days you stayed in Connecticut you would still be a Connecticut "tax resident" so you would file as a CT resident.

Thank again! To be more clear:

Apartment in Connecticut (Renting) -> I live the whole year and working full-time from this address.

Home in New York (Own since December 2019) -> My parents live here and no income from NY.

Please review this Turbo tax link, for further guidance on owning a home with your parents. Basically though, since it sounds like you co-own the house with your parents, you can claim the part of your ownership interest in the property.  Assuming that it is a 50/50 split in ownership, you can claim 50% of the mortgage payments, property taxes and all of the deductible expenses for owning the house. If all three of you have their names on the deed, then it would be a 1/3 split.

it doesn't matter if you lived in one state and owned the house in another.
