The RUT is the Colombian equivalent of a tax file number. You need one for almost everything.

No RUT, no bank account. No RUT, no property purchase. No RUT, no signing up as a formal utility customer. No RUT, no receiving invoices for professional services.

It's basic infrastructure. Every foreigner living in Colombia — and many who don't but who hold Colombian assets — needs one. Here's the essentials.

What They Are

RUT (Registro Único Tributario) is the tax registration. It's what enrols you in the DIAN's system.

NIT (Número de Identificación Tributaria) is the actual tax ID number you receive when you register. It's what appears on invoices, contracts, and property titles.

For individuals, the NIT is your foreigner ID (cédula de extranjería) number, sometimes with an extra digit. For companies, it's a separate number.

Who Needs a RUT & NIT:

• Anyone becoming a Colombian tax resident.

• Anyone buying property in Colombia, resident or not.

• Anyone opening a Colombian bank account.

• Anyone doing formal business in Colombia — being a partner in a Colombian company, receiving formal invoices, being an employer.

• Anyone with a Colombian visa (the M-Pensionado paperwork prompts registration).

• Anyone intending to make income while living in Colombia.

You don't need one just as a tourist, but you need to be aware of when you officially stop being a tourist and start being a tax resident, because it’s not just about the visa (check out our article on Colombian tax residency).

How to Get a RUT & NIT:

The application is free (no mandatory government fees).

If you have a Colombian visa, registration is straightforward: arrange an appointment with the DIAN, present a passport and cédula, complete the form. If you’re an FTR client, we send a bilingual local partner with you to arrange the appointment, physically take you there, help translate, fill out the forms and ensure you have the correct documents, and it’s usually done in a single visit/session.

If you don't have a visa but need a RUT (typical case: foreign buyer of Colombian property), the process is doable but requires either a Colombian legal representative (such as one of FTR’s local partners) acting under power of attorney, or a formal application through the DIAN's foreign taxpayer channel.

Timing: a week or two total for a straightforward case, longer if paperwork isn't clean.

What Can Go Wrong:

• Applying under the wrong "responsibilities code" — the DIAN classifies taxpayers by activity, and being coded wrong can create obligations you don't have, or miss ones you do.

• Registering a foreign address that later becomes hard to receive DIAN correspondence at.

• Not updating the RUT when your circumstances change (new address, new activity, new visa status).

• Assuming registering just makes you visible — it also creates obligations. Once you have a RUT and are a tax resident, filings are due whether or not you owe.

Cost of Getting It Right

A local accountant or tax lawyer, such as FTR’s local partners, will handle the registration correctly for a modest fee, and file your first return properly. The cost is trivial compared to fixing an incorrectly-coded RUT later.

For foreigners with any complexity — investment income, foreign assets, multiple currencies — starting with professional help is worth doing.

REMEMBER: In Colombia if you make a purchase (such as property) without your paperwork in order, your legal title over the property could be voided. Don’t let real estate agents and sellers rush you into a purchase (THEY WORK FOR THE COMMISSION, NOT FOR YOU!) - you need to either get your own trusted representative or do your own homework to avoid huge headaches later.
