Foreign nationals who spend more than 183 days in Colombia within any rolling 365-day period become Colombian tax residents under Article 10 of the Estatuto Tributario (Tax Code), a rule that DIAN, the Dirección de Impuestos y Aduanas Nacionales (National Tax and Customs Administration), applies to worldwide income and assets, not only to what a foreigner earns inside the country; the 2025 personal income tax window ran from August 12 to October 24, 2025, staggered by the last two digits of each filer’s RUT number.
The number of foreign residents in Colombia has grown steadily since 2015, and with it the number of individuals who cross the tax residency threshold without realizing it; the 183-day clock runs across any rolling 12-month window, not just a calendar year, meaning a foreigner who divided time between Colombia and their home country in 2024 and 2025 may qualify as a resident for tax year 2025 even without spending 183 continuous days in the country in that calendar year alone.
How to determine whether a filing obligation exists
Tax residency triggers a filing obligation only when at least one of five annual thresholds is reached: net worth at year-end above US$64,000 (at the current exchange rate), or any of the following annual totals exceeding US$19,900 — total income, credit‑card charges, purchases, or bank deposits.
A significant point of professional debate is whether these figures count Colombian activity only or worldwide activity, and the conservative position among experienced Colombian accountants includes worldwide figures.
Non-residents who never crossed the 183-day threshold still face filing obligations if they earned Colombian-source income in 2025, covering property sales, business activity, services to Colombian clients, or loans to Colombian residents; those filers use DIAN Form 110 and declare only what Colombia generated rather than the full worldwide picture that applies to residents.

What to prepare and when to engage an accountant
Colombia’s tax return process runs on documentation in three clusters, and a foreign filer should start gathering all of them by January of the filing year to avoid delays: worldwide annual financial statements (all banking, brokerage, and investment accounts, with Colombian banks typically issuing annualized statements in March), worldwide income documentation (employment certificates, contractor records, dividend statements, rental income, and any tax withholding certificates from Colombian clients), and deduction documentation (health insurance premiums, education expenses, dependent certificates, and charitable payment records).
Worth noting, foreign documents may require official translation and apostille (a certified authentication recognized by DIAN), adding weeks to preparation timelines that are already tight in years when a filer arrives late to the process; Colombian employment certificates from local employers are due each March, and Colombian bank statements require either a branch visit or a written request to obtain in annual format.
Tax rates, additional obligations, and the cost of non-compliance
All Colombian tax calculations rely on the UVT (Unidad de Valor Tributario or Tax Value Unit), a base metric that DIAN adjusts annually for inflation to set brackets, filing thresholds, and penalties without rewriting the tax code each year.
Colombia’s progressive income tax scale for 2026 starts with a tax-free band up to 1,090 UVT (approximately US$14,000), rises through brackets of 19%, 28%, and 33%, and reaches a maximum rate of 39% for income above 31,000 UVT; the source of income matters too, as salary income generally faces a higher effective rate than dividend income, a distinction that Colombian accountants factor into the filing structure from the start.
Residents with net income above US$159,000 in 2025 face an additional Información Exógena (external accounting report) obligation, and those with assets above US$1 million must also file a separate wealth tax report with 50% of the obligation due between May 10 and May 24 and the remainder by September 13 of the same year; the minimum DIAN penalty for non-compliance is 10 UVT, late filing carries a 5% monthly surcharge on tax owed, and failure to file at all risks penalties reaching 200% of total tax value, with DIAN authorized to seize Colombian bank accounts and real estate to recover unpaid obligations.
The truth is, tax enforcement against foreign residents in Colombia has intensified since 2021 as DIAN invested in cross-referencing financial data from banks, notaries, and migration records; foreign residents who own property, operate businesses, or hold brokerage accounts in Colombia face a growing probability of detection, and the professional consensus is consistent: retaining an accountant experienced with foreign filings before the August deadline is cheaper by several orders of magnitude than resolving a DIAN audit after it.
