To satisfy my curiosity with accurate tax returns, I decided to compare returns from using TurboTax Deluxe 2021 and FreeTaxUSA web site. In my particular case, I reported interest on US Savings Bonds from Box 3 in Form 1099-INT. Here is one obvious discrepancy. FreeTaxUSA excluded interest on US Savings Bonds in line 10 of Michigan 2021 Schedule 1 and hence, I don't owe Michigan state tax due. Unfortunately, TurboTax Deluxe 2021 failed to exclude interest on US Savings Bonds in line 10 of Michigan 2021 Schedule 1 and hence, I owe Michigan tax due. For this reason, I decided to file my federal and state returns with FreeTaxUSA web site. I checked the instructions for Michigan 2021 Schedule 1 to confirm that interest on US Savings Bonds is supposed to be excluded. I just wanted to point out this discrepancy so you can update TurboTax software for Michigan tax return.
