A property in Colombia can carry tax consequences in two countries at once, and neither is settled at the sales office. What follows are not answers: they are the questions a buyer from Bogotá needs settled before signing, and who to put them to.
We do not state here which countries have a treaty with Colombia, nor what anyone is required to declare, and the reason is practical: those lists and rules get amended, and one wrong assertion would repeat across every page. What can be set out is how the problem is built. There are two tax administrations with their own rules; there are two moments treated differently —holding the property, with its rental income, and selling it, with its ganancia ocasional (the gain taxed on sale)— and there is a personal condition, tax residence, which is not chosen but determined by rules and which changes what is withheld and what is filed. The DIAN is the authority on the Colombian side; the other side needs an accountant in that country; and the Cancillería explains the apostille of the certificates each administration will ask the other for. The seller substitutes for none of those three conversations.
The mortgage comes from a Colombian bank, against a local credit history, not from a bank abroad and not from the seller: the bank pulls your record from the centrales de riesgo, the credit bureaus, asks for proof of income and orders its own avalúo, the appraisal, and title study. Whoever answers for the approval is the bank's mortgage department, not the sales office. Ask in writing for the approval letter and the disbursement instructions, because each disbursement is supported by a different document: first the promesa de compraventa, the purchase promise, and then the escritura once registered with the mortgage recorded on it. The money does not enter through the regulated exchange market and there is no foreign investment to register with the Banco de la República; what does have to be assembled is proof of the source of funds, which is a separate matter and is requested by the bank and the notaría. You can sign in person, so no poder and no apostille are needed, yet you manage the property from another city: settle who receives it, who pays the predial, the property tax, and the building fee, and who issues the paz y salvo, the clearance certificate, before each step. What sets you apart from a Medellín buyer is not the law, which is the same, but the channel: your file is usually studied in the city where you live. Tax questions go to the DIAN and to an accountant.
In Castillogrande the typical deal is not a unit in a condominium but a house and its lot, which puts the weight of the file back on the chain of title to the land: you climb through the deeds to the parcelación, the original subdivision that created the block, because those platting deeds registered conditions, setbacks and easements that still bind and that are invisible from the street. There is no building manager to issue a paz y salvo, a no-arrears certificate, and no assembly to settle anything, so boundary questions with a neighbor are argued between private parties and what governs is the title and the survey, not a set of house rules. The counterparty is usually an old city family and, fairly often, a family company that owns the property: then you must decide whether to buy the real estate or the company's shares, two different transactions with different paperwork and different exposure, and request the certificado de existencia y representación, the corporate good-standing and signing-authority certificate, together with the resolution approving the sale. And because the neighborhood is fully built out, any construction is permitted on an already developed lot, with neighbors entitled to take part in the proceeding.
What is specific to Castillogrande
The residential tip of the peninsula: lower and quieter than Bocagrande, facing the bay, with little street retail. Houses and low-rise buildings sit alongside new towers, and single-family homes still exist. It is a dead end: access is through Bocagrande with no through road at the far tip, which keeps it free of passing traffic.
- whether the property faces the bay or the open sea, because the swell, the smell and the façade upkeep are not comparable
- what building height the rules allow on the lot, which is not uniform across the peninsula and is the first fact omitted when a lot is sold
- how ground stability was addressed, given this is land reclaimed from the sea, and what the soil study for the building says
What to verify, step by step
- Ask the DIAN, about your own case, how tax residence is determined, what is reported in Colombia for holding the property and what is reported on its sale, and which withholdings apply to someone who is not a tax resident.
- The questions a buyer from Bogotá has to settle before closing: what the bank requires in order to study the loan, who approves it and which document supports each disbursement, asked in writing before you sign the promesa; what proof of source of funds the bank and the notaría want, which is not the same thing as registering foreign investment and who receives the property, who pays the predial and the building fee, and who issues the paz y salvo while you live in another city.
- Take those same questions to an accountant in your own country and ask in writing whether a treaty exists between Colombia and that country and, if it does, what it says about rental income and about ganancia ocasional. That answer is theirs to give, not the DIAN's and not ours.
- Ask the Cancillería which tax-residence certificates and which documents need an apostille or legalisation for one administration to accept them from the other.
- Before transferring, confirm with the Banco de la República how the investment ends up registered, because the exchange registration is what later supports moving funds out, and the tax question is asked on that basis.
- Decide with your accountant, before the promesa and not after, whether you buy personally or through a company, because the titleholder does not change without another deed.
Mistakes that cost money
- Asking about tax after signing. The structure of the purchase is decided beforehand, and it is the only part still open to choice.
- Assuming a treaty exists because someone said so in a buyers' group. Whether one exists, and what it says, is confirmed in writing by an accountant in each country.
- Believing that if tax was withheld in Colombia there is nothing left to do at home. There are two administrations and two separate filings; how they interact is exactly the question to settle.
Frequently asked questions
- Is there a treaty between Colombia and my country?
- We neither assert nor deny it here: the list is amended and a stale answer would cost you money. Ask the DIAN and an accountant in your own country, and get the answer in writing.
- Will I pay twice on the same thing?
- That is the right question and it has no general answer: it depends on your tax residence, on each country's rules and on whether a treaty exists. It is the conversation to have with an accountant in each country before signing.
- Can a buyer from Bogotá handle this without an accountant?
- The DIAN explains the Colombian side, but neither administration resolves the combination of the two for you. That is what the accountant in each country is for.
