My question is do I just log into Turbo Tax and do my taxes as normal? I know I should file married but separate as my British husband doesn't have a SSN. Also, I usually filed Federal and State taxes. How do I file state taxes if I no longer live in a state? Is that fact not applicable this year as my employment for 2018 WAS in a state? Are there any special forms I need to print or mail or do anything this year?
I won't be able to answer all your questions, but can answer at least one.
"How do I file state taxes if I no longer live in a state? Is that fact not applicable this year as my employment for 2018 WAS in a state?" -
If the State or States you resided in have taxes and you met residency requirements, then yes, taxes must be filed. Very few states have no taxes. (How I miss Nevada and no taxes!)
BTW, you can submit as Married Jointly, but your husband would need to go to US Embassy get passport verified, and file for a ITIN. Annoying and time consuming but the tax return is very nice! But only do this if you want additional stress, I had this problem. (US Customs and USPS wanted to keep the US Embassy notarized document for two weeks. They kept blaming the other.) But if you choose Married Jointly Filed, the foreign income exclusion comes into play assuming husband makes less than approx $90k a year. (I do my taxes yearly through TurboTax.)
Good luck with taxes!
