Trading one property for another is one of the oldest operations in the market — and also one of the least understood when it comes to calculating taxes. There are two versions: a simple exchange and an exchange with a cash balance (torna), when one side pays a cash difference. The distinction between the two completely changes the income tax math.
Why this is the question for someone who wants to trade, not sell
Compare the two scenes below — the same desire to trade one property for another, two different agents:
- Agent who doesn't know: client asks "can I trade my apartment for a bigger one, paying just the difference?" Answer: "I can try to find someone interested." The client never finds out this trade has a specific legal name and its own tax rules, much more favorable than selling and buying separately.
- Agent who knows: same question. Answer: "that's an exchange with a cash balance — you trade your property for the bigger one and pay only the difference in cash. And income tax applies only to that difference, not to the full value of the new property." The client discovers the operation they thought was complicated is actually cheaper on taxes than selling and buying.
What an exchange (permuta) is
A property exchange is trading one asset for another — in real estate, one property for another, or land for finished units (common in developments, when the landowner "trades" the land for apartments built on it). It doesn't have to involve any money: if both properties are worth the same, the trade is just that, a trade.
Exchange WITHOUT a cash balance: no value difference
When both properties traded have the same value, there's no cash difference to pay — and no capital gain to report. In practice, the old property's acquisition cost simply "carries over" to the new property, with no income tax due. But careful: transfer tax (ITBI) still applies — and it applies twice, since each party must pay ITBI on the property they're receiving (see ITBI and ITCMD).
Exchange WITH a cash balance: when values differ
If the properties traded have different values, whoever is receiving the more valuable one pays the difference in cash — that difference is called a torna (cash balance/equalization payment). Here's the detail worth its weight in gold: capital gains income tax applies only to the cash balance, not to the total value of the deal.
Example — calculating a swap between two apartments
A client trades their apartment (worth R$750,000) for a bigger one (worth R$900,000), paying the difference in cash:
| Item | Value |
|---|---|
| Client's property (given up in the trade) | R$ 750,000 |
| Property received | R$ 900,000 |
| Cash balance paid | R$ 150,000 |
Capital gains income tax, in this case, is calculated only on the cash balance (R$150,000) — not on the R$900,000 of the property received. That's already a huge saving compared to selling the old property and buying the new one as two separate transactions.
The exemptions that can zero out the tax
- Cash balance under R$35,000: exempt from income tax.
- The single-property rule up to R$440,000: if the property given up in the trade is worth up to that limit and the taxpayer hasn't sold or traded another property in the last 5 years, the operation can also be exempt — the same rule that applies to a regular sale.
The change Brazil's 2026 Tax Reform brings
Under the Tax Reform, a pure exchange (no cash balance) stays outside the scope of the new IBS and CBS taxes — it continues to be treated as a simple trade of assets. But the cash balance itself gets treated as a sale, subject to IBS/CBS on that cash portion. Worth keeping an eye on this if the deal is planned for after the transition.
In practice: what to ask before doing a property exchange
- Do both properties have the same value, or will there be a cash balance? That changes the entire tax math.
- Is the transfer tax being calculated on both sides? Each party pays their own, on the property they receive.
- Is the cash balance under R$35,000? If so, it may be exempt from income tax.
- Have I already used the single-property exemption in the last 5 years? Confirm before counting on it.
The difference this makes in a broker's career
Many clients who say they "want to sell to buy another" actually just need a well-structured exchange — with less tax and less paperwork than two separate transactions. An agent who offers that solution, instead of just pushing a traditional sale, solves the client's real problem and saves them money on taxes.
