A 1031 exchange can be mechanically perfect, every deadline met, every document signed, and still produce a tax result the investor did not expect if their CPA was not consulted on the specific numbers involved. This work never gives tax advice directly; it exists to make sure the investor's own tax advisor has what they need, early enough to actually use it.
The qualified intermediary administers the exchange mechanics, holding funds and processing the exchange agreement, but the QI does not evaluate the investor's specific tax position. Whether a given identification choice creates boot, how debt replacement compares between the relinquished and replacement properties, and what the eventual Form 8824 will need to show are all questions for the investor's own CPA, not the intermediary.
Waiting until filing season to loop in the CPA is the most common and most avoidable mistake in this part of the process. Debt levels on both properties, any cash the investor plans to pull out of the transaction, and the specific closing statement figures all need to reach the CPA while there is still time to adjust the structure, not after the exchange has already closed and the numbers are fixed.
Some El Paso investors work with a CPA based elsewhere in Texas or out of state, and some replacement candidates involve a DST sponsor or QI outside the immediate market. When several advisors are spread across different firms and time zones, someone has to keep the actual facts, sale price, debt figures, closing dates, consistent across every conversation, since a stale or slightly wrong number relayed secondhand to a CPA can lead to an incorrect boot calculation or a mismatched Form 8824 draft. Sending the same source documents directly to every advisor, rather than summarizing them differently each time, closes that gap.
A short list of coordination points, run at the right moments, prevents most of the surprises that show up at tax time.
An investor who structures the entire exchange first and brings the CPA in only to file the return can discover, after everything is closed, that a debt mismatch created unexpected boot or that a cash distribution the investor thought was minor triggered a larger taxable gain than expected. At that point the transaction is done and there is no fixing it retroactively. A single conversation with the CPA before identification, grounded in the actual sale numbers, is what keeps that surprise from happening, and it costs far less time than untangling a surprise tax bill the following spring.
