By the Numbers
The headline first, because there was real worry about this: the 1031 like-kind exchange is still fully intact in 2026. You can still sell an industrial building and defer the capital-gains tax by reinvesting in replacement property. Nothing in the recent federal tax law removed it for real estate. If you’ve been holding off on a sale because you heard 1031 might go away, that reason is gone.
This is a timely companion to our evergreen 1031 Exchange Guide for Industrial Owners, which covers the full mechanics. This piece focuses on what’s actually different heading into 2026.
The core rules didn’t change
The structure owners already know still applies: 45 days from the sale to formally identify replacement property, 180 days to close, a qualified intermediary holding the proceeds, and replacement property that is like-kind and of equal or greater value to defer the full gain.
For California industrial owners, the usual complications still apply: industrial replacements have zoning, environmental, and clear-height requirements that can make the 45-day window tight. Line up candidates before you close the sale, not after.
The deadline trap that can quietly cost you
Here’s the wrinkle worth flagging. Your 180-day exchange period actually ends on the earlier of two dates: 180 days after the sale, or the due date of your tax return for that year.
That means if you sell late in the year—roughly after mid-October—your tax-return due date can arrive before your full 180 days are up. To preserve the entire window, you generally need to file an extension (Form 4868) for that year’s return. Miss it, and your exchange period gets cut short, sometimes by weeks you were counting on to close.
Pro Tip: Confirm the year-end detail with your CPA
This is general information, not tax advice. The Form 4868 extension step is a small administrative move with a large consequence—any owner closing a sale in Q4 should confirm it with their tax advisor and qualified intermediary before year-end.
What it means for timing your sale in 2026
With 1031 confirmed and cap rates expected to hold through mid-year, the calculus for owners sitting on appreciated industrial is straightforward: the tax-deferral tool you rely on is still there, and the market for stabilized small-bay assets remains healthy. If your building has below-market rents, you can sell into that upside and roll the full proceeds—untaxed—into a property that better fits where you’re headed. The one thing not to do is improvise the timeline.
