I build a spread sheet for all the forms and worksheets that require calculations. FreeFillableForms does some of the calculations for you, and does not have any worksheets. Excel has formulas for everything I have encountered paying taxes, and I have a joint account with stock options and several rental property LLCs.

As a bonus, the spreadsheets are generally reusable, after checking to make sure there are no changes.

FreeFillableForms is great and has saved me a ton of time, but it does not do the calculations automatically for every field. You still have to manually lookup certain things from tables. It's freakin' frustrating, because there's no reason why it couldn't automate those as well.

Even more frustrating because it doesn't tell you that you haven't done the calculation or worse, you haven't transferred a field from one form to another.

I failed to copy my self-employment tax back to my 1040 for 2020, despite having calculated it correctly. No warnings, the form filing went smoothly, and 4 months later I got a notice from the IRS.

It's insanity.

I hear you. I keep hoping they will add more calculations in future versions, and they do, little by little.

My suspicion is that it is deliberately deprecated due to pressure from for-profit tax prep companies.
