Yes. You can use TurboTax Online on any PC or Mac with a current web browser. You can also use the TurboTax mobile app for iOS and Android devices to do your taxes on your smartphone or tablet.

However, it is not compatible with TurboTax Desktop/Download editions. 

in addition to my question, how can i transfer last years returns from a PC to a mac?   I’ve been using turbo tax for years but using windows PC   So before i transition to a mac, is this possible to import last years returns?   thanks. 

Yes, you can transfer from TurboTax download to TurboTax Online edition. 

In TurboTax Online, how do I transfer my information from my previous year's tax return?

I got a new computer. How do I transfer my TurboTax CD/Download file from last year into this year's...

Thank you for choosing TurboTax.
