Hi! See below for my feedback so far: 

1) On a Sch C, I noticed that the summary was correct (total income, AGI, etc), but the breakdown of the Sch C was incorrect. Gross receipts was accurate, but expenses were not, for the 2021 baseline. 

2) I couldn't easily figure out whee the differences in the federal payments and credits were coming from. 

3) I think in the wording for Balance Due or Refund, you should put (parentheses) around the one that will reflect as a figure in parentheses -- i.e. Balance Due/(Refund) if the refund amt will be represented in parentheses.

4) I was under the impression that ITA wasn't taking state info into account (yet).. if that's the case, how did it provide state refund/balance due figures? 

5) Some of the strategies seem redundant, or like they should be combined (i.e. 401k/403b employer and employee contributions)

6) Why suggest student loan payment assistance via employer if the taxpayer and/or spouse didn't pay any interest expense? Is it because they may have paid it, but they were phased out due to income?
