GoSystem Rs and ProSystem FX are the Rolls Royce of international returns but they also cost the most.

I was told UltraTax is also very capable but ATX, which costs about the same but handles international returns much better than Lacerte/ProConnect, would be my go-to if I am to leave Intuit.

It's a shame Intuit does only a half-baked job with international returns and not put in enough effort to make them fully functional.
