Hypothetical question
English isn't my first language so bear with me. I am a fully remote software developer. My employer is based in New York. I lived in New Jersey from January to April, moved to Florida from May to September, and have been in Texas since October. I did not step foot in my employer's NY office all year.
My employer has been withholding NY state income tax all year. My accountant says I may owe taxes to NJ and possibly NY under the "convenience of the employer" rule, but not to FL or TX (no state income tax). This seems insane — I could owe taxes to a state I never worked in?
Has anyone dealt with multi-state tax issues as a remote worker? Do I need to file in all three states plus NY?
