Tax and W-9 tracking gives you one place to collect and track tax documents for every payee on your books, from artists and promoters to vendors and staff. It sits alongside payouts, venue-level tax rates, and GL codes, so the tax side of the business lives with the money side instead of in a separate folder somewhere.
When it is time to settle a show or close the month, missing paperwork is what slows you down. Keeping W-9s and other tax documents tracked per payee means you are not chasing forms after the fact, and your books close on the numbers you already have.
