Hello - I am a permanent Massachusetts resident. I am about to take a job with an Illinois based company. I will remain a permanent Masachusetts resident and work fully remote from home in Massachusetts for my new employer based in Illinois. Which state would I have to pay income taxes to and would I have to pay taxes to both states? I understand Massachusetts has a "convience of the employer" rule but I don't know if that would apply to me.
Thank you for any insight as I may have to back out of my new job for financial reasons if I'm forced to pay double state taxes.
