DIAN Exogenous Information for Individuals: How to Consult the Third-Party Report

Every year, as income tax filing season approaches in Colombia, thousands of individuals face the same question: what information does DIAN have about my income, bank accounts, and assets? The answer lies in the report of exogenous information (also known as the report of information reported by third parties), a key document issued by DIAN that consolidates financial movements reported by banks, employers, notaries, and companies during the previous taxable year.

1. What is exogenous information and why is it essential before filing?

Tax exogenous information is the set of data that legal entities and individuals obligated to report periodically provide to DIAN regarding their transactions with third parties. For an individual, this file includes checking and savings account balances as of December 31, withholding taxes applied, salaries and fees received, credit card purchases, and real estate transactions carried out at notaries.

It is crucial to understand the legal nature of this document: DIAN reiterates that the report is strictly for guidance purposes. The presence or absence of data in the Excel file does not exempt the taxpayer from their legal obligation to declare their full economic reality based on their own supporting documents, such as bank statements and income certificates.

2. Prerequisites for accessing the DIAN transactional portal

Before attempting to download the third-party report on DIAN's MUISCA platform, ensure you meet the following basic requirements:

• Have an active Unique Tax Registry (RUT). If you need to make changes to your contact or activity details, you can see our guide on how to update economic activity in the RUT online.
• Have an enabled account and access password on the DIAN Transactional Portal.
• If you have just registered with the RUT for the first time, the system usually takes approximately one week to enable the exogenous download option for your user.

3. Step by step: How to consult and download the exogenous report in Excel

The consultation process is 100% digital and free of charge. Follow these steps within the institutional platform:

1. Go to the official DIAN website (www.dian.gov.co) and click on the button Transactional Portal.
2. Select the option Registered User. In the login form, choose the 'In my own name' option and enter your document type, identification number, and password.
3. In the main menu of the Transactional Zone, locate and select the icon or link called Consult Information Reported by Third Parties.
4. Accept the tax confidentiality notice and terms of use of the information (the data is protected by articles 583 and 584 of the Tax Statute).
5. Select the taxable year you wish to consult (for example, the year to be declared) and click 'Download'. The system will generate a compressed file or an Excel workbook (.xlsx).

4. How to interpret the columns and concepts of the DIAN file

When you open the downloaded Excel file, you will see thousands of rows organized by different fields. The key columns you must audit carefully are:

Review real estate or vehicle purchases and service provision contracts with special attention. If you provide independent services, remember the importance of the supporting document for non-invoicing entities to properly back up your costs and deductions before the tax authority.

5. What to do if you find errors or inconsistencies in your report?

It is very common to find inconsistencies: duplicate income, omitted withholdings, or balances that do not match your bank statements. In this regard, you must keep in mind that DIAN cannot directly modify or correct data reported by third parties.

The legal protocol requires that you directly contact the company, bank, or person who made the error in the report and request the issuance of a certificate or the formal correction of their exogenous format using DIAN's pre-validator. Once the third party presents the correction, consult the report again and keep the request, the certificate, and the supporting documents for the change.

6. Control of income, personal sales, and asset support

Financial movements derived from personal sales, vehicles, or real estate are automatically recorded in DIAN data crosses when they are made through banks or notaries. Keeping an organized record of your financial support documents and asset sales is essential to explain variations in wealth and respond with evidence if DIAN requests clarification. When tax treatment depends on your specific case, confirm it with an accountant.

According to active ads on Colombia Move (August 2026), the vehicles section had 11 active posts. It is a concrete reminder that if you sell an asset, it is advisable to save the ad, the payment receipt, and the delivery record as part of your traceability.

Frequently asked questions

❓ What is DIAN's exogenous information for individuals?

It is a downloadable Excel report that consolidates the financial and tax information that banks, companies, notaries, and legal entities reported to DIAN about your transactions during a taxable year.

❓ Why might the exogenous values not match my bank statements?

Financial institution reports may include different cutoff dates, consolidated transactions, or reporting errors that must be cross-referenced directly with your official printed statements and certificates.

❓ Does exogenous information replace my suggested income tax return?

No, exogenous data is a compilation of raw information submitted by third parties, while the suggested tax return is a preliminary assessment proposal prepared by the DIAN based on those information cross-checks.

❓ What should I do if a third party reported income or purchases I do not recognize?

You must contact the reporting entity directly to request payment verification and the correction of the exogenous information with the DIAN, as the tax authority does not modify third-party data at the taxpayer's request.

❓ Can I check the exogenous information of a family member or client from my user account?

No, information is protected by tax confidentiality according to Articles 583 and 584 of the Tax Statute; only the account holder or their legal representative with power of attorney formalized in the RUT can access such data.

❓ How long after registering for the RUT can I download my third-party report?

Once you create and activate your account on the DIAN Transactional Portal, the system enables the link to view information reported by third parties approximately one week later.
