Children and property are easily handled by the IRS; people with more sophisticated needs (inheritance, meaningful donations, investments) could still hire a professional to adjust what the IRS calculates. That's effectively what's happening now anyways, its just the IRS doesn't let you take their calculation at face value, you have to file your own and see if it matches. Instead they could just send you "This is what we calculated" and you can do nothing (probably 90% of people) or file as we do today for the special cases you mentioned.
