Moving to Medellín: Complete Financial & Tax Checklist for Expats

Medellín has exploded as one of the world's most popular expat destinations — and for good reason. The climate is eternal spring, the cost of living is a fraction of the US or Europe, and the city has transformed into a vibrant hub for entrepreneurs and remote workers. But financial and tax preparation before and after you arrive is non-negotiable. This checklist saves you from the costly mistakes most expats make in their first year.

Before You Arrive: Pre-Departure Checklist

Determine your tax residency situation at home: Will moving to Colombia affect your tax residency status in your home country? In the US, you're taxed regardless; in many EU countries, you can formally exit tax residency.

File required exit filings (if applicable): Some countries (Canada, Germany, Australia) require formal exit tax returns or notifications when you become non-resident.

Get your apostilled documents: Passport copies, birth certificates, professional credentials — apostille them in your home country before departing. It's much harder logistically to do from abroad.

Open a Wise account: For seamless international transfers while you're getting established.

Create a day-counter system: Start tracking your days in Colombia from day one. This determines your colombian tax residency status.

Within Your First Month in Colombia

Apply for the right visa: Depending on your purpose (investment, remote work, pension, tourism), apply for the appropriate visa through Migración Colombia.

Get your Cédula de Extranjería: Once your visa is approved, register with Migración Colombia to receive your foreign ID card — essential for banking, DIAN registration, etc.

Register with DIAN and get your NIT: Even if you don't have income in Colombia yet, registration prepares you for future tax obligations.

Open a Colombian bank account: Bring your passport, cédula, NIT, proof of address, and income documentation to Bancolombia or Davivienda.

Register any international wire transfers (Formulario Cambiario): Every time you bring money into Colombia from abroad, document the transaction.

Ongoing Annual Financial Tasks

File Colombian income tax return (if required) by April–June deadline
File home country tax return (especially mandatory for US citizens)
Maintain FBAR and FATCA filings if you're a US citizen with foreign financial accounts
Update your DIAN RUT if your tax profile changes
Review your tax residency status each year (especially the 183-day count)
Renew your visa and cédula de extranjería before expiration

If You're Starting a Business

Register your SAS with the Cámara de Comercio
Set up electronic payroll (nómina electrónica) before hiring
Register for IVA if your revenue will exceed the threshold
Open a separate corporate bank account
Hire a bilingual Colombian CPA firm from day one

Cost of Living Context

Many expats are surprised that while Medellín is significantly cheaper than their home country, the administrative and compliance costs (accounting, legal, banking) are proportionally significant for small incomes. Budget for at least USD 200–400/month in professional accounting services to stay compliant — it's worth every penny compared to DIAN penalties.
