Property Taxes (Predial) on Oaxaca Land: What Owners Pay

If you ask about property taxes Mexico predial is the term that comes up first in every conversation about owning land on the Oaxaca coast — the annual municipal tax you pay every single year you hold a lot. The bill is small, the rules are simple, and the cost of ignoring it is out of proportion to the amount.

This article covers what predial is, what it costs along the coast, how the bill is calculated, what happens if you do not pay, and the taxes at purchase and at sale. The short version: predial is cheap, ISAI is the cost of buying, and capital gains (ISR) is the cost of selling.

The tax

Predial: the property tax, explained

Predial is the annual property tax charged by the municipality where the land sits; the name comes from predio, the Spanish word for a piece of real estate. It is a local tax, separate from the federal system — the income tax (ISR), the value-added tax (IVA), and everything else the federal tax authority (SAT) collects. You do not file for predial in April. You pay a bill, once a year, at the municipal treasury.

It is worth saying what predial is not. It is not a wealth tax, and it is not tied to residency — foreigners pay the same predial as Mexican nationals on the same lot, because the tax follows the property, not the owner. There is no return to file and no accountant required; you pay the bill and you are done for the year.

On this coast, "the municipality" means the town hall of the district your lot belongs to: Mazunte and San Agustinillo fall under Santa María Tonameca; Zipolite and Puerto Ángel under San Pedro Pochutla; Santa Elena and Ventanilla under Santa María Colotepec. Puerto Escondido is its own municipality, and Huatulco's bays fall under Santa María Huatulco. Each has its own treasury window and its own rates within state guidelines.

Bills are typically issued at the start of the year, and many municipalities offer a discount — commonly 10 to 15 percent — for paying in January or February. After that the full amount applies, and late in the year the surcharges start to creep in. Owners who pay early treat it as a January chore, like renewing a passport or changing the oil.

The amount matters less than the receipt. A current predial receipt is the standard proof that a property is being maintained and claimed — you will be asked for it when you buy, when you sell, and whenever the lot needs verification. Owners who treat it as a small annual chore rarely think about it again; owners who skip it learn how much a few hundred pesos a year was worth.

What you pay

What owners actually pay

The honest range for a vacant lot on the Oaxaca coast is the low thousands of pesos a year — roughly 1,000 to 5,000 MXN, or about 50 to 250 USD at recent exchange rates. That is the range we hear consistently from owners from Mazunte down to Huatulco for unimproved land.

Built properties pay more, because construction adds value to the cadastral record, and lots in the prime zones — the beachfront strips, the hillsides above Zipolite, the master-planned bays of Huatulco — bill higher, though still modestly by international standards. A house with a pool in a good zone might run 8,000 to 15,000 MXN a year. None of these figures is a quote; the number that counts is the receipt the current owner can show you — ask for it before you make an offer.

To put it in context: a typical American homeowner pays around one percent of the home's value in property tax every year — $3,000 a year on a $300,000 house. Here, the same value of land commonly bills a few hundred dollars, sometimes less than a hundred. Whatever you pay for the lot — our 2026 price report on Oaxaca coast land prices by town gives the indicative ranges — predial is not the cost that will shape your budget.

The mechanics are easy. In Puerto Escondido and Huatulco you can often pay online or at bank windows; in the smaller towns you take the bill to the municipal treasury and walk out with a stamped receipt. If you are away, a neighbour or property manager can pay on your behalf — the receipt is issued to the property, not the person at the window.

How it's calculated

How predial is calculated

Predial is not calculated on what you paid, and not on what the lot would sell for today. It is calculated on the valor catastral — the cadastral value — the number the municipal catastro (the cadastre office) assigns to the property for tax purposes.

That value is typically far below market value — commonly a fraction of the sale price, and on the coast the gap can be wide because the market has moved faster than the municipal records. The predial rate, a small percentage set by each municipality, applies to that low base, which is why the bills stay low. The system is not generous by design; it is simply slow, and the slowness works in the owner's favour.

Reassessments happen, but they lag the market. Municipalities update their cadastral tables from time to time, and new construction triggers a fresh look at the property. When a house goes up, the catastro raises the value of the lot and the bill climbs with it. But an unimproved lot can keep the same modest valor catastral for years. Do not assume the gap will last forever — it tends to narrow over time — but do assume that while you hold the lot, the bill will stay small.

If you don't pay

What happens if you don't pay

If you do not pay predial, the debt does not go away. It accrues interest and surcharges (recargos), and it attaches to the property itself, not just to your name. Years of unpaid predial become a lien on the lot, and liens surface at the worst moment: at sale.

Before a notario will close a sale in Mexico, the title is checked for liens, and the predial history is part of that check. Outstanding predial must be settled before the transfer can proceed — either you pay it, the buyer pays it and deducts it from the price, or it comes out of the sale proceeds. In bad cases, where the debt has compounded over many years or the municipal records are tangled, it can delay the closing for weeks and add legal fees to the bill.

The fix is boring and cheap: pay it. Think of predial as the cheapest insurance you will ever buy on the lot. A few thousand pesos a year keeps the record clean, keeps the lien register empty, and keeps your name attached to the property in the municipal books. On this coast, where some titles are actas de posesión rather than full escrituras, a paid-up predial record is also evidence of possession that strengthens your hand in any dispute.

One exception is worth knowing. If the land is still ejido — communal farmland that has not been converted to private title — predial may not apply in the usual way, because the ejido itself holds the land and collects its own dues. The moment a parcel is regularized into an escritura, predial becomes an owner's bill like any other. We cover the conversion process in our guide to ejido land in Mexico.

At purchase

The taxes at purchase

Predial is what you pay every year. At the moment of purchase, a different tax applies: ISAI, the impuesto sobre adquisición de inmuebles — the state acquisition tax. In Oaxaca it runs roughly 2 to 5 percent of the declared value of the property, and it is the largest single line item in your closing costs.

ISAI is separate from predial, and it is separate from the notary's fees and the registry fees that complete the picture. Together they add up to roughly 5 to 8 percent on top of the purchase price for a straightforward closing. The full breakdown — what each line item is, how the notario calculates it, and the questions to ask — lives in our guide to closing costs when buying land in Oaxaca.

Worth noting: ISAI is calculated on the value declared in the escritura, and the notario guides that declaration within the law. Declaring a low value to trim the tax is evasion, and a licensed notario will not facilitate it. The declared value is also the base for your capital-gains calculation at sale, so a low declaration costs you more later than it saves now.

One thing to check at purchase: whether the seller's predial is current. The notario will verify it, but ask the seller directly for the latest receipt before you sign. Unpaid years will surface at closing one way or another; better to know the number in advance than to watch it come out of the proceeds.

At sale

The tax when you sell

When you sell, the federal government wants its share of the gain. Capital gains in Mexico are taxed as ISR — impuesto sobre la renta, the income tax — at roughly 25 percent of the gain after deductions: the difference between your adjusted acquisition cost and the sale price. Deductions can include the inflation adjustment to what you paid, your purchase closing costs, and improvements you made.

The notario withholds the ISR at closing and pays it to the tax authority, so you do not file anything separately. But the calculation is the notario's, and the assumptions in it are worth reviewing. If you are a foreign resident selling a lot bought years ago, the numbers get nuanced — consult a tax professional before you sign the promesa de compraventa, and again before closing. It is a few thousand pesos for advice that can save multiples of that.

Keep every receipt from your purchase — the escritura, the ISAI payment, the notary's invoice — because they become the deductions that reduce your taxable gain at sale. Buyers who kept nothing pay tax on a gain that looks larger than it was. The appreciation itself, the plusvalía, is the subject of our piece on land appreciation on the Oaxaca coast; the proof the property was cared for is the folder of receipts you kept.

The buyer will ask to see your predial receipts — every serious buyer and every notario wants a clean, current record before closing, and a seller who can produce years of paid receipts closes faster and negotiates from a stronger position.

The whole picture in one table:

Tax	When	Rough cost
Predial (municipal property tax)	Every year	1,000–5,000 MXN for a vacant coastal lot
ISAI (state acquisition tax)	At purchase	2–5% of the declared value
ISR (capital gains)	At sale	Roughly 25% of the gain after deductions

The whole system, in three lines: predial is the small annual tax that keeps your record clean, ISAI is the tax at purchase, and ISR is the tax at sale. None of it is complicated enough to avoid, and none of it is expensive enough to fear. Pay the bill, keep the receipts, and let the notario handle the rest.

A final note: the ranges here are indicative, not quotes, and your notario's written estimates are the only numbers that count. But the shape — small annual bills, a meaningful tax at purchase, a meaningful tax at sale — is stable across the coast, and it is a shape you can plan around.
