Facts and circumstances. There's no set method, but you'll need to present some documents showing the IP you own in a QOZB is being put to work in the business itself. I have two things to add on this front. If you're thinking of trying to game the system by putting unrelated IP into the QOZB so you can get tax-free treatment on it while technically meeting the statutory and regulatory requirements, don't do it. If the IRS catches wind of it, they'll apply the anti-abuse rules.
