> If they get something wrong and end up paying more tax than they need to there will never be a second thought given to it. Anecdotally, I messed up copying tax owed from the table a couple years back, and the IRS sent me a letter telling me I made a mistake and overpaid, along with a check for the difference. In any case, a lot of the complication in the tax code comes down to the government incentivizing certain behaviors, so it makes sense that we should put more focus on teaching people to read the rules and find out what those incentives are. Of course a free calculation tool to run simulations could help people to understand those rules, and we ought to make the actual filing more convenient for everyone.
