Monthly Compliance Checklist for Business in Colombia: 2026 Guide

Running a business in Colombia is not only about selling, hiring, invoicing, or growing.

Every month, your company must stay aligned with tax, payroll, accounting, social security, electronic invoicing, and corporate obligations. Missing one deadline may create penalties, interest, cash flow problems, or issues with the DIAN, UGPP, Chamber of Commerce, or local tax authorities.

The good news? Business compliance in Colombia becomes much easier when you follow a clear monthly checklist.

In this 2026 guide, we explain what your company should review every month, which obligations depend on your NIT, and which tasks should be monitored throughout the year.

Why monthly compliance matters for any business in Colombia

Colombia has several layers of business compliance.

Your company may have national tax obligations before the DIAN, payroll and social security obligations through PILA, local tax obligations such as ICA, corporate duties before the Chamber of Commerce, and electronic reporting duties such as electronic invoicing, payroll support documents, and exogenous information.

The DIAN publishes monthly national tax deadlines for 2026, including income tax, VAT, withholding tax, and other national obligations depending on the taxpayer’s classification and NIT.

This means compliance should not be handled only at the end of the year. It should be part of your monthly routine.

Monthly compliance checklist for a business in Colombia

This checklist is designed for companies operating in Colombia in 2026. Some obligations apply to all businesses, while others depend on your tax responsibilities, economic activity, city, number of employees, and tax regime.

Use it as a monthly control tool, but always confirm your specific deadlines with your accountant or legal advisor.

1. Review your DIAN tax calendar

Your first monthly task should be checking the official DIAN tax calendar.

Deadlines in Colombia are often based on the last digits of your company’s NIT. This means your due date may be different from another company’s, even if both businesses have the same tax obligation.

Every month, confirm whether your company must file or pay:

• Withholding tax
• VAT
• National consumption tax, if applicable
• Income tax installments, when applicable
• Simple Tax Regime obligations, if applicable
• Foreign assets report, if applicable
• Exogenous information, if scheduled
• Other special national taxes

The DIAN’s 2026 tax calendar page lists monthly tax deadlines and links to the official monthly due dates.

Practical tip

Do not rely on last year’s calendar.

Even if the obligation is the same, the exact due date may change every year. Create a monthly reminder to check the official DIAN calendar before the first week of each month.

2. File and pay withholding tax, if applicable

Many companies in Colombia act as withholding agents.

If your company withholds income tax, VAT withholding, or stamp tax withholding, you may need to file and pay withholding tax monthly.

This is one of the most important recurring obligations because it directly affects third-party payments, vendor relationships, and DIAN compliance.

Before filing, review:

• Supplier invoices
• Professional service payments
• Employee-related payments
• Contractor payments
• VAT withholding, if applicable
• Withholding certificates
• Accounting records
• Previous month corrections

Monthly withholding must be checked carefully because errors can affect your tax return, your suppliers’ tax records, and your company’s deductible expenses.

3. Check VAT obligations

If your company is responsible for VAT, you must confirm whether your VAT filing period is bimonthly or quarterly.

This depends on your business in Colombia activity, income level, and tax classification.

Even if VAT is not filed every month, it should still be reviewed monthly.

Why? Because VAT depends on your invoices, purchases, credit notes, debit notes, and accounting records. Waiting until the filing deadline can create inconsistencies that are harder to correct.

Each month, verify:

• VAT generated on sales
• VAT paid on purchases
• Credit and debit notes
• Electronic invoices issued
• Valid supplier invoices
• VAT withholding
• Differences between accounting and invoicing software

4. Keep electronic invoicing up to date

Electronic invoicing is a central part of business in Colombia compliance.

The DIAN’s electronic invoicing system includes electronic sales invoices, electronic payroll support documents, support documents for purchases from non-invoicing suppliers, equivalent documents, and RADIAN.

Every month, your company should verify that:

• All sales were invoiced correctly
• Invoices were validated by the DIAN
• Credit and debit notes were issued when needed
• Invoice numbering is active and not expired
• The invoicing software is working properly
• Rejected invoices were corrected
• Supplier invoices meet DIAN requirements

Practical tip

If your company issues many invoices, do a weekly review instead of waiting until month-end. This helps prevent rejected documents, missing income, and tax inconsistencies.

5. Issue support documents for purchases from non-invoicing suppliers

Sometimes your company buys goods or services from people or a business in Colombia that are not required to issue electronic invoices.

In those cases, the buyer may need to generate a support document for acquisitions from non-obligated suppliers.

According to the DIAN, this document supports the purchase of goods or services when the supplier is not required to issue an electronic invoice, and it is needed to support costs, deductions, or deductible VAT when applicable.

Each month, review:

• Payments to non-invoicing suppliers
• Contractor or small vendor payments
• Required support documents
• DIAN-authorized numbering
• Accounting treatment
• Deductibility support

This is especially important for companies that work with independent contractors, small vendors, informal suppliers, or occasional service providers.

6. Transmit electronic payroll support documents

If your company has employees and wants to support payroll costs and deductions for income tax purposes, it must properly generate and transmit the electronic payroll support document.

DIAN doctrine states that the electronic payroll support document must be transmitted within the first ten business days of the month following the payroll payment or accrual.

Every month, review:

• Salarios
• Bonuses
• Overtime
• Commissions
• Payroll deductions
• Social security deductions
• Severance-related accruals
• Ajustes de nómina
• Electronic payroll transmission status

Practical tip

Payroll, PILA, and electronic payroll should match. If one system says one thing and another system says something different, the inconsistency may create tax or labor risks.

7. Pay social security and payroll contributions through PILA

Employers in Colombia must pay social security and parafiscal contributions through the Planilla Integrada de Liquidación de Aportes (PILA).

The UGPP explains that authorized information operators calculate and process parafiscal payments through PILA, allowing the entry, modification, validation, and correction of contribution concepts.

Each month, confirm:

• Health contributions
• Pension contributions
• Labor risk contributions
• Family compensation fund contributions
• SENA and ICBF, if applicable
• Employee income base
• New hires
• Terminations
• Leaves of absence
• Salary changes
• Payroll news reported correctly

This obligation is not just administrative. Incorrect PILA payments can trigger UGPP reviews, penalties, and retroactive payments.

8. Review payroll and labor compliance

Beyond PILA, your company should review labor compliance every month.

This includes making sure contracts, payroll payments, benefits, and employee records are consistent.

Monthly labor review should include:

• Employment contracts
• Contractor agreements
• Salary payments
• Overtime
• Commissions
• Vacation accruals
• Sick leave
• Maternity or paternity leave
• Disciplinary records
• Terminations
• Occupational health and safety updates

If your company hires foreigners, also review visa status, work authorization, and reporting obligations where applicable.

9. Check local taxes: ICA, ReteICA, and municipal obligations

National taxes are not the whole picture.

Most companies also have municipal tax obligations, especially Impuesto de Industria y Comercio (ICA) and, when applicable, ReteICA.

The exact rules depend on the municipality where your company operates. Bogotá, Medellín, Cali, Barranquilla, Cartagena, and other cities may have different filing periods, rates, and deadlines.

For example, Bogotá’s official 2026 tax calendar refers taxpayers to the district rules for ICA, ReteICA, and other district taxes.

Every month, review:

• City where income was earned
• ICA activity codes
• Applicable ICA rates
• ReteICA withheld by clients
• ReteICA to be withheld from suppliers
• Municipal filing periods
• Local tax portal access
• Payment receipts

Practical tip

If your company operates in more than one city, do not assume one ICA filing covers everything. Multi-city operations require careful municipal tax mapping.

10. Update your accounting records

Monthly accounting is the foundation of compliance.

If your books are not updated, every tax return becomes harder.

Your accounting team should reconcile:

• Cuentas bancarias
• Credit cards
• Sales
• Compras
• Nómina
• Taxes payable
• Accounts receivable
• Accounts payable
• Inventory
• Loans
• Fixed assets
• Intercompany transactions

This review helps detect missing invoices, duplicate payments, unrecorded income, and tax inconsistencies before they become larger problems.

11. Review RUT updates

El RUT is your company’s tax identification record before the DIAN.

It includes your company’s address, economic activities, tax responsibilities, contact information, and other taxpayer data.

The DIAN states that RUT updates are free and that taxpayers must update RUT information within one month after the event that caused the change.

Every month, ask:

• Did the company change address?
• Did the company change email or phone number?
• Did it add a new business in Colombia activity?
• Did its tax responsibilities change?
• Did the legal representative change?
• Did the company open or close a commercial establishment?

If the answer is yes, review whether the RUT must be updated.

12. Review Beneficial Ownership Registry changes

Companies in Colombia must also monitor the Registro Único de Beneficiarios Finales (RUB).

The DIAN’s RUB guidance explains that legal entities and certain structures must report beneficial ownership information electronically. It also states that companies must determine whether there were changes as of January 1, April 1, July 1, and October 1, and update the RUB within the following month if changes occurred.

This means RUB is not necessarily a monthly filing, but it should be part of your monthly compliance review.

Check whether there were changes in:

• Shareholders
• Ultimate beneficial owners
• Ownership percentages
• Control structures
• Management rights
• Trusts or similar structures
• Foreign ownership chains

13. Monitor exogenous information obligations

Exogenous information is one of the most sensitive reporting obligations in Colombia.

It allows the DIAN to cross-check information reported by taxpayers, clients, suppliers, banks, and other third parties.

The DIAN’s official exogenous information page lists the applicable regulations for taxable years 2025 and 2026, including the 2026 resolutions and technical annexes.

Even though exogenous information is not filed every month, it should be prepared monthly.

Why? Because waiting until the reporting season can make it difficult to identify missing tax IDs, incorrect names, incomplete supplier data, or inconsistent accounting entries.

Each month, review:

• Third-party identification
• Supplier and client NITs
• Addresses and tax information
• Payment concepts
• Withholding records
• VAT records
• Accounts payable and receivable
• Accounting classifications

14. Maintain corporate documents and minutes

Corporate compliance is often ignored until a bank, investor, buyer, auditor, or authority requests documents.

Do not wait until then.

Each month, confirm whether your company needs to prepare or update:

• Shareholder meeting minutes
• Board meeting minutes
• Powers of attorney
• Legal representative appointments
• Shareholder registry
• Share transfers
• Capital increases
• Bylaw amendments
• Commercial establishment updates
• Contracts with partners or related parties

This is especially important for foreign-owned companies, subsidiaries, SAS companies, and companies with multiple shareholders.

15. Check Chamber of Commerce obligations

The Chamber of Commerce is not only relevant when you create a company.

Your company must keep its registration updated and renew its commercial registration annually.

The Bogotá Chamber of Commerce explains that companies that fail to renew their commercial registration or registration for five years may be removed from the registry; legal entities may be dissolved and enter liquidation, while individuals and establishments may have their registration canceled.

Although renewal is annual, monthly compliance should include checking whether any corporate changes need to be registered.

Review:

• Legal representative changes
• Address changes
• Commercial establishment changes
• Business activity changes
• Share capital changes
• Bylaw amendments
• Pending renewals
• Certificates needed for banks or contracts

16. Review contracts, vendors, and invoices

Your legal and tax risks often start in your contracts.

Each month, review your main vendor and client relationships to confirm:

• Contracts are signed
• Payment terms are clear
• Tax clauses are included
• Withholding responsibilities are defined
• Invoices match the contract
• Services were actually delivered
• Support documents are complete
• Foreign payments have proper documentation

This is especially important for companies paying foreign vendors, software providers, consultants, agencies, freelancers, or related companies abroad.

17. Check cash flow for upcoming taxes

Compliance is not only about filing.

It is also about having cash available when taxes are due.

Each month, prepare a tax cash flow forecast including:

• VAT payable
• Withholding tax
• ICA or ReteICA
• Payroll contributions
• Income tax installments
• Annual tax obligations
• Accounting and legal fees
• Possible penalties or corrections

A company that plans its tax cash flow has fewer surprises and avoids using operating cash to cover missed obligations.

18. Keep digital evidence organized

Colombian compliance is document-heavy.

If your company is ever audited, reviewed, or asked to correct information, you will need evidence.

Each month, save:

• DIAN filings
• Payment receipts
• Electronic invoices
• Payroll support documents
• PILA receipts
• Extractos.
• Contratos.
• Accounting reports
• Withholding certificates
• Local tax filings
• Certificados de Cámara de Comercio
• Corporate minutes

Use organized folders by year, month, and obligation.

The most common mistakes include:

• Checking tax deadlines too late
• Assuming all taxes are national

• Not reconciling electronic invoicing with accounting

• Filing PILA with incorrect salary or employee information
