Colombia Tax Registry (RUT) and Tax Number (NIT)

What it is

You need Colombian tax registration (RUT) and a tax identification number (NIT) when your tax or reporting duties require registration with DIAN. Foreign nationality alone does not answer whether you must register before a property purchase.

The RUT is DIAN's tax registry. The NIT is the tax identification number. Read DIAN's definitions and registration instructions before choosing a registration route.

Before closing, ask a Colombian accountant to assess your purchase, planned use and tax residence. Ask the notary and bank which identification they need. Do not treat passport identification as proof that you have no tax duties.

What are the RUT and NIT?

The DIAN tax registry page explains the difference:

Type	Rule
Tax registry (Registro Único Tributario, RUT).	This is DIAN's record of your identity, location, activities and responsibilities.
Tax identification number (Número de Identificación Tributaria, NIT).	This is the unique number used to identify you for tax, customs and exchange-control matters.

The RUT is the registration; the NIT is the number. Neither replaces your passport or foreigner ID card. They also do not replace investment registration with Banco de la República.

Who it applies to

Buying, renting, selling and filing

Buying. DIAN's list includes foreign investors who must meet formal duties. It also includes non-residents who have Colombian tax obligations. The test is your obligations, not simply your citizenship. Confirm your duties before paying or signing. This guide does not establish a general RUT exemption for buyers.
Renting out. Colombian property rent is Colombian-source income under Estatuto Tributario, article 24. Review registration, invoicing and return obligations before you start. See rental income tax for foreign owners.
Selling. Gains from Colombian property are also Colombian-source income. A transfer of foreign investment can require a transaction-specific tax return under article 326. Arrange the RUT and filing process with your accountant before the sale. See selling and sending the proceeds abroad.
Filing a return. DIAN requires registration when you must file. For foreign individuals without Colombian tax residence, article 592(2) provides a filing exception when all income was subject to withholding under articles 407–411 and that withholding was made. Other non-residents must check the rules that apply to them. Do not assume that any withholding, or the absence of rent, settles every tax duty.

DIAN says registration generally comes before the economic activity or the obligation. It also gives a specific deadline tied to the return for individuals who become income-tax filers during the year. Ask which rule applies to you; do not wait until the filing day to resolve your identity documents.

Steps

How to apply from Colombia or abroad

Check the available channel. Start at DIAN's registration page. Its published self-service instructions use a Colombian citizen ID. Do not assume the same process will accept a foreign passport.
Use assisted registration when needed. The rules allow in-person registration, directly or through a duly authorised representative.
Confirm the appointment type offered for your case. The representative does not have to be a lawyer.
Consider video assistance. DIAN lists RUT registration by video appointment, regardless of your country of residence.
Follow the appointment email and submit the documents through the channel it identifies.
If you are abroad and cannot use the other channels, DIAN provides a request route through its complaints and requests service, PQSR. Its instructions for individuals abroad ask for scans of identity documents and the passport showing departure. If migration policy means there is no departure stamp, provide the written departure date as instructed.
Ask DIAN how to document your situation if you have never entered Colombia.
Keep the completed certificate. A request or draft is not a completed registration. DIAN sends the RUT certificate after it validates and formalises the process.

Costs

Cost and common mistakes

DIAN says RUT registration and its form are free. A representative or translator may charge a separate professional fee; agree that fee in advance. DIAN also says a bank account is not required to register.

For the purchase sequence, return to the buying guide. Educational information, not legal or tax advice. Have a Colombian accountant determine your obligations.

Documents

Which documents should you prepare?

The RUT rules, article 1.6.1.2.11 of Decreto 1625 as amended by Decreto 678 de 2022, require an identity-document copy and presentation of the original for an individual. The DIAN identification manual recognises a valid passport for foreigners who do not use a foreigner ID card under the registration rules.

Your identity document and a clear copy.
Your correct address, country of residence, email and telephone information.
Your actual economic activity and the tax responsibilities your accountant identifies.
If someone applies for you, your document copy, the representative's document and the power of attorney.

For a representative, the rules require the original special power, or a copy of a general power. A general power older than six months also needs a notarial certificate that it remains valid. Confirm how a power signed abroad must be authenticated or translated before you sign it.

Common mistakes

Confusing the RUT with a visa or a title certificate.
Choosing activities or tax responsibilities that do not match your situation.
Leaving an old email address in the record.
Assuming the investment record at the central bank completes DIAN registration.

Frequently asked questions

Are a RUT and a NIT the same thing?

No. The RUT is your DIAN registration. The NIT is the tax identification number used to identify you. Neither is a visa or a foreign-investment registration.

Do all foreign buyers need a RUT before signing?

DIAN ties registration to tax and formal reporting duties. Ask an accountant to assess the purchase and planned use before closing. Confirm the notary and bank requirements. Do not assume a general exemption or a universal rule based only on nationality.

Can I get a RUT from outside Colombia?

DIAN offers video appointments regardless of residence. Individuals abroad who cannot use other authorised channels can request registration through PQSR with the required documents. A passport holder should confirm the available channel rather than assume citizen-ID self-service will work.

How much does DIAN charge for RUT registration?

DIAN registration and the form are free. Any adviser, representative or translation fee is separate.
