Preparation looks backward; planning looks forward
By the time a return is being prepared, nearly every variable is fixed. The preparer's job is accuracy and full use of the positions the year's facts already support. That is valuable work, and it is not the same as changing the facts.
Planning operates upstream. It considers which year income is recognized in, which account type receives a contribution, when an asset is sold, and how a household's taxable, tax-deferred, and already-taxed balances are proportioned over time.
