1031 Exchange
A 1031 exchange lets you sell an investment property and defer capital gains taxes by reinvesting the proceeds into another like-kind property. Named after Section 1031 of the Internal Revenue Code, it is one of the most powerful wealth-preservation tools in real estate investing. Instead of paying 15–23.8% in capital gains taxes on a sale, you roll the equity into the next deal and defer the tax indefinitely.
You do not eliminate taxes with a 1031 — you defer them. But deferral compounds over time: the capital that would have gone to taxes keeps working and earning returns instead.
How it works: the basic mechanics
| Step | What happens | Timeline |
|---|---|---|
| 1 | Sell the relinquished property | Day 0 |
| 2 | Qualified intermediary (QI) holds the proceeds | Day 0 |
| 3 | Identify replacement property(ies) | By Day 45 |
| 4 | Close on replacement property | By Day 180 |
The critical point: you cannot touch the sale proceeds. They must go directly to a qualified intermediary — a third-party exchange facilitator. If proceeds hit your bank account, the exchange is disqualified and the tax becomes due immediately.
The three identification rules
You have 45 days to identify potential replacement properties. The IRS gives you three rule options:
| Rule | How many properties you can identify |
|---|---|
| 3-Property Rule | Up to 3 properties, regardless of value (most common) |
| 200% Rule | Any number of properties, as long as total value ≤ 200% of relinquished property value |
| 95% Rule | Any number, if you acquire 95%+ of identified value |
For most investors, the 3-Property Rule is the simplest and most practical.
What qualifies as "like-kind"
For real estate, the like-kind requirement is broad — almost any real property held for investment or business use qualifies:
| ✅ Qualifies | ❌ Does not qualify |
|---|---|
| Single-family rental → multifamily | Primary residence → investment property |
| Rental → commercial | Investment property → vacation home (personal use) |
| Land → rental property | Real estate → other asset types (stocks, gold, etc.) |
| Domestic property → domestic property | Foreign property → U.S. property |
The property must be held for investment or productive business use — not for resale (flips do not qualify).
What "boot" means and why it triggers tax
Boot is any non-like-kind property received in an exchange — typically cash or net debt relief. If your replacement property is worth less than the relinquished property, or you reduce your mortgage balance, the difference is taxable.
| Scenario | Taxable boot? |
|---|---|
| Reinvest $100% of proceeds into equal or greater value property | No boot — fully deferred |
| Reinvest proceeds but take $15,000 cash back | $15,000 boot — taxable |
| Sell property with $200K mortgage, buy property with $150K mortgage | $50K debt relief = boot |
To fully defer all gains, reinvest into property of equal or greater value and equal or greater debt.
Worked example
An investor sells a rental property purchased for $160,000 (five years ago) for $230,000.
| Item | Amount |
|---|---|
| Sale price | $230,000 |
| Selling costs (6%) | − $13,800 |
| Net sale proceeds | $216,200 |
| Original cost basis | $160,000 |
| Depreciation taken ($5,450/yr × 5 yrs) | − $27,250 |
| Adjusted basis | $132,750 |
| Capital gain | $83,450 |
| Depreciation recapture (25% of $27,250) | $6,813 |
| Long-term capital gains tax (~20% fed + state) | ~$16,690 |
| Tax due without 1031 | ~$23,500 |
| Tax due with 1031 (deferred) | $0 |
The investor can roll all $216,200 into a larger property and keep compounding that $23,500 instead of sending it to the IRS.
Common mistakes
1. Missing the 45-day identification window. The deadline is absolute. If Day 45 falls on a weekend or holiday, the deadline does not move. Start identifying replacement properties before closing on the sale.
2. Using an unqualified intermediary. The QI must be an independent third party — not your attorney, accountant, real estate agent, or anyone who has acted as your agent in the past two years. Disqualified intermediary = disqualified exchange.
3. Failing to identify the right number of replacement properties. If you identify only one property and the deal falls through, you have no backup and the exchange fails.
4. Not understanding depreciation recapture. A 1031 defers capital gains tax but depreciation recapture (at 25%) is also deferred — it stacks up across multiple exchanges. This matters significantly when planning an eventual sale without an exchange.
5. Using proceeds in a primary residence. Moving into the replacement property within two years can expose you to challenges from the IRS regarding investment intent.
Frequently asked questions
Can I do a 1031 on a flip property? Generally no. Flips are held as dealer property (inventory), not as investment property. The 1031 requires that property be held for investment or business use. Properties sold within a year are scrutinized closely. Consult a qualified CPA before attempting a 1031 on a short-hold.
What happens to the deferred taxes eventually? They become due when you sell without exchanging. However, many investors use 1031 exchanges their entire career, deferring indefinitely. At death, heirs receive a stepped-up basis, which can eliminate the deferred gain entirely — though this provision is subject to legislative change.
Can I do a partial 1031 exchange? Yes — you can reinvest part of the proceeds and take some as cash (boot). You pay tax on the boot amount and defer the rest.
Is there a minimum holding period before I can 1031? No specific IRS-mandated holding period, but properties must be held for investment purposes. Most tax advisors recommend holding at least 12–24 months to establish investment intent.
