Every year, as the tax filing season approaches in Colombia, thousands of individuals face the same question: what information does the DIAN have about my income, bank accounts, and assets? The answer lies in the exogenous information report (also known as the information reported by third parties report), a key document issued by the DIAN that consolidates the financial movements reported by banks, employers, notary offices, 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 the DIAN regarding their transactions with third parties. For an individual, this file includes checking and savings account balances as of December 31, tax withholdings applied, salaries and fees received, credit card purchases, and real estate transactions carried out in notary offices.
It is crucial to understand the legal nature of this document: the DIAN reiterates that the report is for strictly guidance purposes only. 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 documentation, such as bank statements and income certificates.
2. Prerequisites for accessing the DIAN transactional portal
Before trying to download the third-party report on the DIAN MUISCA platform, make sure you meet the following basic requirements:
- Have an active Unique Tax Registry (RUT). If you need to make changes to your contact or activity information, you can view our guide on how to update your economic activity in the RUT online.
- Have an enabled account and login password for the DIAN Transactional Portal.
- If you have just registered in the RUT for the first time, it usually takes about a week for the system 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:
- Go to the official DIAN website (www.dian.gov.co) and click on the button Transactional Portal.
- Select the option Registered User. In the login form, choose the 'On my own behalf' option and enter your document type, identification number, and password.
- In the main menu of the Transactional Zone, locate and select the icon or link called Consult Information Reported by Third Parties.
- Accept the tax confidentiality notice and terms of use for the information (the data is protected by articles 583 and 584 of the Tax Statute).
- 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:
| Field / Column | Description and Tax Utility |
|---|---|
| Concept | Internal numerical code from the DIAN that classifies the type of operation (e.g., salaries, deposits, financial yields). |
| Reporter Identification | NIT or ID number of the entity or person who reported the movement (bank, employer, client). |
| Corporate Name / Name | Full name of the company or person who issued the report. |
| Payment or Credit to Account | Total gross amount received or transacted with that third party during the taxable year. |
| Withholding Tax Applied | Amount withheld from you as income tax, which you can deduct in your tax return. |
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 those not obligated to issue invoices 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: duplicated income, missing withholdings, or balances that do not match your bank statements. Given this, you must keep in mind that the DIAN cannot directly modify or correct the 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 that they issue a certificate or formally correct their exogenous format using the DIAN validator. Once the third party submits the correction, consult the report again and keep the request, the certificate, and the supporting documentation of the change.
6. Income control, personal sales, and asset backing
Financial movements derived from personal sales, vehicles, or real estate are automatically registered in the DIAN data crosses when they are carried out through banking entities or notary offices. Maintaining an organized record of your financial supporting documents and your asset sales is essential to explain changes in net worth and to respond with evidence if the 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 vehicle section had 11 active posts. This is a concrete reminder that, if you sell an asset, it is advisable to keep the ad, payment receipt, and delivery record as part of your traceability.
Frequently Asked Questions
❓ What is the DIAN exogenous information for individuals?
It is a downloadable report in Excel that consolidates the financial and tax information that banks, companies, notary offices, and legal entities reported to the DIAN regarding your transactions during a taxable year.
❓ Why might the exogenous values not match my bank statements?
Financial institution reports may include different cut-off dates, consolidated transactions, or reporting errors that should be cross-referenced directly with your official printed statements and certificates.
❓ Does the exogenous information replace my suggested income tax return?
No, the exogenous information is a compilation of raw data sent by third parties, whereas the suggested return is a preliminary settlement proposal prepared by the DIAN based on such data cross-checks.
❓ What should I do if a third party reported income or purchases that I do not recognize?
You must contact the report issuer 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 request of the taxpayer.
❓ Can I check the exogenous information of a family member or client from my user account?
No, the information is protected by tax secrecy according to articles 583 and 584 of the Tax Statute; only the account holder or their proxy with legal representation 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 query information reported by third parties approximately one week later.
