1031 exchanges for Austin infill and redevelopment lots
The IRS clocks do not care about Austin site plan. If you are selling a lot or trading into one, structure the exchange before you list.
A 1031 lets you defer federal gain when you sell real property held for investment or productive use and buy other like-kind real property. Since 2017 that means real property only. Vacant land is generally like-kind to improved property. Dealer inventory held primarily for sale is not.
The hard part in Central Austin is not the definition. It is the calendar. You have 45 days from the sale to identify replacement property. The exchange period ends on the earlier of 180 days after the sale or the due date of your tax return for that year, including extensions. Austin entitlement, utility letters, and tree or drainage comments do not pause those clocks.
Pick the structure before you are under contract
Forward exchange: you sell first, a Qualified Intermediary holds proceeds, you identify within 45 days, and you close by the earlier of 180 days or your tax return due date, including extensions. This works when you already have a realistic replacement or two and the lender can hit the date.
Reverse exchange: you need the replacement lot before you can sell. An Exchange Accommodation Titleholder holds title under the IRS safe harbor (Rev. Proc. 2000-37 / 2004-51). More cost, more moving parts, often the only way to buy a 78731 or Clarksville lot that will not wait.
Improvement / construction exchange: you need site work or a building to count toward replacement value. Treat the work as something that has to be completed and received within the exchange period, not merely started. Reverse and improvement are often combined on redevelopment dirt.
Austin land use is not a footnote
IRS final regulations look to state and local law to decide what counts as real property. Recorded easements, plats, long-term leaseholds, and development rights can matter. So can how you document intent.
HOME amendments, Site Plan Lite, and Infill Plats can shorten some small-project paths. They can also create a false sense of speed. Model the actual permit path for that lot before you bet an exchange on it.
Debt, QI, and boot
To fully defer tax you usually replace both equity and debt, or add cash to cover the gap. Contracts need to be assignable to the QI. Escrow should be set so you never constructively receive the funds.
Cash or other non-qualifying property you take out is taxable boot. Report the exchange on Form 8824. Hire the QI and a 1031-literate CPA or tax attorney before you list — not after the first offer.
Property tax is a separate problem
A 1031 does not freeze Travis Central Appraisal District. New units and new construction typically show up in assessed value. Plan for a higher tax bill after you build. Appeal if the number is wrong; do not assume the exchange protected you.
- Do not treat developer inventory as eligible 1031 property.
- Do not miss day 45, or the earlier of day 180 and your return due date.
- Do not use an uninsured, inexperienced QI.
- Do not ignore related-party rules.
- Do not underwrite Austin permits as if they were a Houston suburb.
