Every buyer budgets for the property's price. Few budget for the two taxes that show up right after: one when you buy, another when you leave it as an inheritance. One is municipal, the other is state-level — and confusing the two has already cost more than one client a poorly planned tax bill.
Why this bill catches people off guard
Compare the two scenes below — the same signing moment, two different agents:
- Agent who doesn't know: client asks "what about taxes?" Answer: "it's just a small percentage." The client finds out at the registry office they need another check for tens of thousands of reais they didn't plan for.
- Agent who knows: same question. Answer: "the transfer tax here is X%, calculated on the actual transaction value — and the city can't set that value on its own, you're guaranteed that right by Brazil's Supreme Court of Justice. And if this ever becomes an inheritance, Santa Catarina's inheritance tax is progressive, between 1% and 7%." The client arrives at the registry office with zero surprises.
ITBI: the purchase tax (municipal)
ITBI (Real Estate Transfer Tax) is charged by the city whenever a property changes owner through a sale — the buyer pays it, and payment is required to register the deed. Each municipality sets its own rate:
| City | General rate | Financed via SFH (housing finance system) |
|---|---|---|
| Balneário Camboriú | 3% of market value | 1% |
| Itapema | 1.5% (until Dec 31, 2026, rising to 2% in 2027) | 1% |
| Porto Belo | 2% of market value | — |
A Porto Belo detail worth knowing: the city doesn't allow title divisibility — meaning every transfer generates a separate ITBI charge, even in split transactions.
The trap of the city's "reference value"
Here's the information that protects a buyer's wallet the most: Brazil's Superior Court of Justice (STJ, Topic 1113) ruled that ITBI's tax base is the actual transaction value — not a "reference value" the city sets unilaterally, and not the property tax (IPTU) value either. The value declared by the buyer carries a presumption of good faith; the city can only challenge it by opening its own administrative process, with proof the value is well below market. In other words: if a city tries to charge ITBI on a reference value higher than the actual price paid, that can be contested.
ITCMD: the inheritance and gift tax (state-level)
ITCMD (Inheritance and Donation Tax) has nothing to do with buying and selling — it applies when a property passes hands through inheritance or gift, and the rate is set by the state, not the city. In Santa Catarina, since Law 19.053/2024, the tax is progressive for spouses and direct-line relatives (parents, children, grandparents, grandchildren):
| Value bracket | Rate |
|---|---|
| Up to R$ 20,000 | 1% |
| R$ 20,000 to R$ 50,000 | 3% |
| R$ 50,000 to R$ 150,000 | 5% |
| Above R$ 150,000 | 7% |
For collateral relatives or unrelated beneficiaries, the rate is a flat 8%, with no progression.
Example — the math on a high-end inheritance
A R$3,000,000 property inherited by a child (direct line), calculated bracket by bracket:
| Bracket | Math |
|---|---|
| Up to R$ 20,000 | 1% × R$ 20,000 = R$ 200 |
| R$ 20,000 to R$ 50,000 | 3% × R$ 30,000 = R$ 900 |
| R$ 50,000 to R$ 150,000 | 5% × R$ 100,000 = R$ 5,000 |
| Above R$ 150,000 | 7% × R$ 2,850,000 = R$ 199,500 |
| Total | R$ 205,600 (≈ 6.85% effective rate) |
Notice that since most of the value falls in the top bracket, the final effective rate lands very close to 7% — the lower brackets barely move the needle once the asset is worth millions.
A planning detail worth mentioning
A lifetime gift with a reserved usufruct cuts the ITCMD tax base in half, because the donor keeps the right to use the property while alive — it's one of the most common estate-planning tools. This isn't legal advice (that's a conversation for a lawyer and accountant), but it's the kind of information that shows a client you understand the subject beyond the sale itself.
In practice: what to ask before closing
- What's the ITBI rate in this city, and what value is it calculated on? Confirm it isn't an inflated reference value set by the city.
- Is the financing through the SFH system? The rate usually drops to 1% in that case.
- Is this property part of any estate plan? That's a conversation worth having with a lawyer beforehand, not after.
The difference this makes in a broker's career
ITBI and ITCMD don't sell a property — but knowing how to explain both, with the actual numbers for that specific city, is the kind of detail that makes a client feel they're dealing with someone who sees the whole transaction, not just the commission. And that's what turns into a referral to the friend who's also about to inherit, buy, or sell.
