Preserve accurate transaction and delivery evidence without promising the buyer a tax outcome. Seller, broker, buyer and adviser responsibilities should be clarified before closing.
Record what actually happens
Keep executed purchase documents, price allocation, delivery records, dates, locations and relevant communications. If a seller statement is requested, ensure it accurately describes known facts and is reviewed through the proper channels. Do not backdate evidence or describe a delivery or first use differently merely because a party hopes to support an exclusion.
Clarify collection and reporting roles
The CDTFA aircraft guide distinguishes dealer and broker purchase situations and discusses buyer reporting where tax was not collected. Have advisers determine which facts apply to the actual seller and transaction. Avoid a general promise that no tax applies, that another party necessarily handles it or that out-of-state delivery alone resolves the California analysis.
Separate purchase tax from other consequences
Buyer sales/use tax, annual property tax, seller income-tax issues and contractual allocations are different questions. A simple seller proceeds estimate should state what has not been modeled. Ask the seller's accountant to assess reporting, basis and potential tax consequences using actual ownership and use history rather than a website's illustrative cash calculation.
Coordinate facts before delivery changes
If location, date, operator or ownership structure changes, notify the tax, legal and operating advisers. Confirm which additional records are needed and how they will be retained securely. A sound documentation plan captures genuine events as they happen and makes review easier; it cannot manufacture eligibility that the underlying facts do not support.
Illustrative seller scenario
Illustrative only: delivery moves from the agreed location to a California airport because of an operational issue. The team should update the closing record and obtain fresh tax advice based on the actual events. Reusing an earlier statement with the original delivery location would create inaccurate evidence rather than preserve the intended plan.
