Colombia Tax Filing Guide 2026 — DIAN E-Filing, Deadlines & UVT Thresholds

Overview — Tax Filing Obligations

Colombian taxpayers have several recurring tax filing obligations:

Income Tax (Impuesto a la Renta): Annual return filed the following year. Individuals: due by August each year. Corporations: due by April each year (for calendar-year entities). Tax is calculated on the previous year's income at progressive rates for individuals (0-39%) and flat 35% for corporations.

IVA (VAT): Monthly or bimonthly returns depending on taxpayer classification. Standard rate 19%. Returns are due between the 15th and 20th of the following month/period, based on NIT digit.

ICA (Industry and Commerce Tax): Municipal tax filed monthly or bimonthly to the local municipality. Rates vary (0.2-1.4% of revenue in Bogotá). Filing dates vary by municipality.

Withholding Tax Returns: Monthly returns for tax withheld at source (retención en la fuente). Due between the 15th and 20th of the following month.

UVT — The Foundation of Thresholds

The UVT (Unidad de Valor Tributario) is the index-linked unit used throughout Colombian tax law:

UVT Value 2026: Approximately COP 47,000 (the exact value is published annually by the DIAN in January, indexed to CPI). The UVT adjusts each year to maintain real value.

Role in Filing Thresholds: Most filing obligations, exemptions, and tax brackets are expressed in UVTs rather than fixed COP amounts. This means thresholds automatically adjust for inflation each year.

Key 2026 Thresholds (in UVTs):

• Individual filing obligation: Gross income > 1,400 UVTs (~COP 65.8 million) or net worth > 4,500 UVTs (~COP 211.5 million)
• VAT registration threshold: Taxable turnover > 1,700 UVTs (~COP 80 million)
• Wealth tax threshold: Net worth > 106,000 UVTs (~COP 5,000 million)
• Simple tax regime (SIMPLE): Gross income < 3,500 UVTs
• Common tax regime: Above SIMPLE thresholds

Annual Income Tax Return — Individuals

Individual taxpayers must file the Declaración de Renta Personas Naturales (Form 210):

Deadline (2026): August 2026 for the 2025 tax year. The exact date depends on the last two digits of your NIT. The DIAN publishes a filing schedule (calendario tributario) each year with specific dates. Typically, the filing window opens in early August and closes in late August or early September.

Who Must File: Individuals must file if any of the following apply for 2025: gross income ≥ 1,400 UVTs (~COP 65.8 million), net worth ≥ 4,500 UVTs (~COP 211.5 million), credit card or credit purchases > 1,400 UVTs, total bank deposits > 1,400 UVTs, or if you are required to file for any other reason specified by DIAN.

What to Report: All worldwide income (for residents): employment income, business income, capital gains, rental income, dividends, interest, crypto gains, and foreign income. Deductions: social security contributions (health, pension), mortgage interest (up to 1,200 UVTs), education expenses (up to 960 UVTs), medical expenses, and charitable donations.

Tax Calculation: Taxable income is calculated as gross income minus deductions. The progressive rates for 2026 are: 0% on the first 1,090 UVTs, 19% on the next band, then 28%, 33%, 35%, 37%, and 39% on income above 38,000 UVTs (~COP 1,786 million). The exact brackets are subject to annual adjustment.

Annual Income Tax Return — Corporations

Legal entities file the Declaración de Renta Personas Jurídicas (Form 110):

Deadline (2026): April 2026 for the 2025 tax year (calendar-year entities). The exact date depends on the last digit of the NIT. Filing typically opens in early April and runs through late April.

Tax Rate: 35% flat corporate income tax rate for 2026. Certain industries may have different rates (e.g., financial institutions may have surcharges). Free trade zone companies may have reduced rates.

Quarterly Advance Payments: Corporations must make quarterly advance payments (anticipos) of income tax, calculated based on the prior year's tax liability. The first quarterly payment is due in April, with subsequent payments in June, September, and December.

Special Rules: Transfer pricing documentation is required for transactions with related parties abroad exceeding certain thresholds. Thin capitalization rules limit interest deductions. Controlled foreign corporation (CFC) rules may apply to foreign subsidiaries.

IVA — Monthly/Bimonthly Returns

VAT (IVA) returns are filed through the MUISCA system:

Filing Frequency: Bimonthly for small taxpayers (ingresos brutos under COP 300,000 million) and monthly for large taxpayers (ingresos over COP 300,000 million). Some taxpayers may qualify for annual filing.

Deadline: Between the 15th and 20th day of the month following the filing period (bimonthly or monthly). The exact day is determined by the last digit of your NIT.

What to Report: Gross IVA charged on sales, IVA paid on purchases (creditable IVA), net IVA payable or refundable. Exports are zero-rated (0% IVA with right to credit input IVA). Exempt activities do not generate IVA on sales but also do not allow input IVA credits.

E-Invoicing Integration: IVA returns are pre-populated from the electronic invoicing system (factura electrónica). The DIAN matches invoices issued and received to verify accuracy. Discrepancies may trigger audits.

ICA — Industry and Commerce Tax

ICA (Impuesto de Industria y Comercio) is a municipal tax filed locally:

Jurisdiction: Each municipality has its own ICA rules, rates, and filing procedures. Bogotá, Medellín, Cali, and other major cities have well-established ICA systems. The tax is on gross revenue from industrial, commercial, and service activities.

Rates: Range from 0.2% to 1.4% of gross revenue, depending on the economic activity. Industrial activities typically have lower rates (0.2-0.7%); commercial and service activities have higher rates (0.5-1.4%).

Filing: Monthly or bimonthly returns filed to the municipal treasury. Deadlines vary by municipality. Returns must be filed even if no tax is due (zero returns).

ICA and Income Tax: ICA paid is deductible against income tax as a business expense. However, ICA is not creditable against IVA.

MUISCA — DIAN E-Filing System

The MUISCA platform is the DIAN's integrated electronic tax system:

Access: All tax filings go through the MUISCA portal (www.dian.gov.co). You need a user account and digital certificate (firma electrónica) to file. Registration is done through the DIAN website with your NIT or CC number.

Digital Certificate (Firma Electrónica): Required for all tax filings. Obtained from authorized certification entities (e.g., Certicámara, Andrés Bello). The certificate is valid for 1-3 years and must be renewed before expiry. Without a valid digital certificate, you cannot file taxes electronically.

Forms: The main forms are: Form 110 (Corporate Income Tax), Form 210 (Individual Income Tax), Form 300 (IVA), Form 350 (Withholding Tax), and Form 2593 (SIMPLE Regime). All forms are available within the MUISCA system.

Payment: Tax payments can be made through the MUISCA system using approved payment methods (ACH, credit card, bank transfer). The system generates a payment receipt (recibo de pago) with a unique Número de Referencia de Pago (NRP).

Penalties & Late Filing

Colombia imposes significant penalties for non-compliance:

Late Filing: Late filing penalty is 5% of the tax due per month or fraction of delay (up to 100% of the tax). Minimum penalty is 10 UVTs (~COP 470,000). Late filing without tax due: penalty of 10 UVTs to 500 UVTs depending on the taxpayer's size.

Late Payment: Interest on late payments accrues at the current banking interest rate plus 50%. The DIAN publishes the applicable interest rate monthly. Interest accrues from the original due date until the date of payment.

Inaccuracy Penalties: If the DIAN finds that your return understated tax by more than 20%, a penalty of 100-200% of the underpaid tax may apply. Fraudulent understatement can lead to criminal charges.

Statute of Limitations: The DIAN can audit returns for 5 years from the filing date (3 years if the return was accurate and complete). Extended to 7 years for cases involving transfer pricing or cross-border transactions.
