I used for tax year 2018 for my two companies... no problem (or at least I thought so then).
Fast forward to tax year 2019 and it is nothing short of a nightmare. First of all, for one of the companies, it shows my 2018 records under 2019 to be filed in 2020! Didn't they file it in 2019 and hence shouldn't be filed again? For another company, it shows nothing for 2018 and nothing for 2019 even though I filed 2019...
I have no way to know and customer support couldn't help.
Will not recommend it, will not use it again... what a pain.
