Tax moves to the front of the year rather than the end of it. Position understood quarterly, provision modeled with the assumptions written down, and the effective rate explained before it appears in the accounts.
On incentives, the qualifying work is captured as it happens — project records, time, technical narrative — so the claim file is built through the year and hands to your preparer complete. That is the difference between a claim that is filed and one that is defended.
Structure is reviewed whenever entities, states or provinces change, because the cost of getting that wrong compounds quietly.
