A:Answer I’ve been using this with MacOS Big Sur so, yes, that works fine. It does include federal e-filing at no extra charge, but this version requires a separate online purchase and download of the TurboTax state product for $40 (which I didn’t realize when I bought it). As far as I can tell, there’s no limit to how many state returns you can file once you’ve bought that product.
This seems like a new overall pricing model compared to what I recall from years past. Under the old pricing model, you could get one state product for free, but then paid about $20 for each state return you e-filed. (You could print and file state returns by mail for free.) So under the new pricing model, you basically break even if you e-file 2 state returns. For everyone that only needs to file one state return for a single state, it works out to be a $20 price increase.
I suppose that if you live in a state that has no state income tax and therefore doesn’t require filing a state return, then this is all you would need and represents a good deal.
