My USC spouse used TaxAct for tax year 2020 -- it did NOT allow e-filing MFS with spouse listed as NRA. While it did allow typing "NRA" on the 1040, when it was time to submit, TaxAct said the 1040 was not eligible for e-filing. My spouse is a W2 employee, no complications about taxes other than NRA spouse at that time. No idea if it's the same with their 2022 tax software. We never used TaxAct after that experience. Felt scammed after paying around $100 for the federal+state bundle, then having to paper-file everything anyway.
