IF..if you use the Desktop program every year, the desktop program has a What-If worksheet that allows you to use the current year's values.....transfer all of them to a next-year column....and then change any of the individual main values to se what would happen in certain situations the next year and the resulting approx. taxes for the next year.
For example, had you used desktop software for 2018 taxes, you could have either used the What-If worksheet to project your expected 2019 taxes under various situations......or copied your 2018 tax return into a new file, and changed the values "as-If" they had occurred in 2018 (yeah...tax rates might change slightly, but usually close enough). The only thing they couldn't deal with is RMD age changes...like those just passed...or a few retroactive changes, since no one can predict what nonsense Congress will come up with.
No, won't do multi-year projections....that's more for some kind of actual financial planning software, but zi suspect that most of those won't actually project the taxes that result.
