If you lived, worked, invested, earned income, used Colombian banks, or owned assets in Colombia during 2025, you may need to file a tax return in Colombia in 2026.
The income tax filing season for individuals starts in August 2026, so now is the right time to review your situation, organize your documents, and avoid last-minute mistakes.
At Nexo Legal, we help foreigners and residents understand whether they must file, what information they need, and how to prepare their income tax declaration in Colombia correctly.
Who must file a tax return in Colombia in 2026?
You must file an income tax return in Colombia in 2026 if, during the 2025 taxable year, you met at least one of the thresholds established for individuals.
For 2026 filings, based on the 2025 taxable year, you may be required to file if you had:
- Total gross assets equal to or above COP $224,095,500
- Gross annual income equal to or above COP $69,718,600
- Credit card purchases equal to or above COP $69,718,600
- Total purchases or expenses equal to or above COP $69,718,600
- Bank deposits, consignments, or financial transactions equal to or above COP $69,718,600
You only need to meet one of these conditions to be required to file.
This is one of the most common mistakes people make: they assume that only high-income earners must declare. In reality, assets, spending, credit card use, and bank movements can also trigger the obligation.
The base article you provided also highlights these same 2026 thresholds and explains that just one condition is enough to create the filing obligation.
Does filing mean you have to pay taxes?
No. Filing a tax return in Colombia is not the same as paying income tax.
You may be required to file because you crossed one of the thresholds, but your final tax due could be zero.
This can happen if:
- Taxes were already withheld at source
- You have deductible expenses
- You qualify for exempt income treatment
- A double taxation rule applies
- Your taxable base is reduced after proper calculation
That is why early planning matters. Filing is about reporting your financial situation correctly. Paying depends on the final result of the tax calculation.
If you are not sure whether your return will generate tax due, it is better to review your case before August. You can start with our income tax declaration service and avoid unnecessary penalties or overpayments.
Are foreigners required to file taxes in Colombia?
Yes, foreigners may be required to file taxes in Colombia if they meet the legal conditions.
Your nationality does not determine whether you file. Your tax situation depends on factors such as:
- How many days you spent in Colombia
- Whether you became a Colombian tax resident
- Whether you earned Colombian-source income
- Whether you own assets in Colombia
- Whether you used Colombian bank accounts
- Whether your worldwide assets or income exceed the filing thresholds
For foreigners, the most important concept is tax residence.
In general terms, you may become a Colombian tax resident if you stay in the country for 183 days or more within any 365-day period. Those days do not need to be consecutive, and the count can cross two calendar years.
Once you become a tax resident, Colombia may require you to report worldwide income and assets, not only Colombian-source income.
What if you are not a Colombian tax resident?
If you are not a Colombian tax resident, your obligation is usually more limited.
Non-residents generally report only:
- Colombian-source income
- Assets located in Colombia
- Certain transactions connected to Colombia
For example, if you live abroad but own an apartment in Medellín that generates rental income, that rental income may create a Colombian tax obligation.
The same can happen if you own real estate, operate a business, receive Colombian payments, or have recurring economic activity in the country.
This is why tax planning is especially important for foreigners who invest in Colombia, rent properties, open businesses, or spend long periods in the country.
When does the 2026 income tax season start?
For individuals, the 2026 income tax filing season for the 2025 taxable year begins in August 2026 and runs until October 2026.
Your exact deadline depends on the last two digits of your Colombian NIT.
According to the official 2026 tax calendar, individuals file between August 12 and October 26, 2026, depending on their NIT. The DIAN calendar page provides access to the official tax calendar and taxpayer services.
This means you should not wait until your deadline month to start.
By August, you should ideally already have:
- Your RUT updated
- Your NIT verified
- Your income certificates collected
- Your bank statements organized
- Your asset information reviewed
- Your deductible expenses identified
- Your foreign assets checked, if applicable
Tax season moves quickly. Waiting until the last week can lead to missing documents, incorrect reporting, penalties, or unnecessary stress.
Why should you start planning before August?
Preparing your tax return in Colombia is not just filling out a form.
A proper income tax declaration requires reviewing your full financial picture for the taxable year.
That includes:
- Income earned in Colombia and abroad
- Salary, freelance income, business income, rental income, pensions, dividends, and capital gains
- Bank account movements
- Credit card purchases
- Real estate and vehicles
- Investments and financial assets
- Foreign assets
- Withholdings and tax credits
- Possible deductions and exemptions
If you wait until August, you may not have enough time to correct inconsistencies, update your RUT, request certificates, translate documents, or clarify your tax residence status.
A good tax plan helps you understand whether you must file, whether you may owe tax, and how to reduce risks legally.
What documents should you prepare?
Before filing your income tax return in Colombia, gather the documents that support your income, assets, expenses, and tax payments.
Useful documents include:
- RUT certificate
- Colombian ID or passport
- Income certificates
- Certificados laborales
- Extractos.
- Credit card statements
- Investment reports
- Property tax bills
- Vehicle ownership information
- Rental income records
- Pension certificates
- Foreign income documents
- Proof of taxes paid abroad
- Certificates of withholding at source
- Documents supporting deductions or exemptions
Foreigners should also review travel dates, visa status, and proof of tax residence abroad if needed.
If you have assets outside Colombia, do not leave this for the end. Foreign accounts, investments, companies, or properties may require additional review.
What happens if you do not file on time?
If you are required to file and you miss your deadline, the DIAN may impose penalties and interest.
The risk is not only financial. Late filing can also affect future tax procedures, refunds, corrections, and your overall compliance history in Colombia.
For foreigners, tax non-compliance can also create problems when investing, opening bank accounts, selling property, applying for certain procedures, or organizing long-term residence in the country.
The safest approach is simple: confirm your obligation early, prepare the return correctly, and file before your deadline.
Common mistakes when filing taxes in Colombia
Many people do not get in trouble because they wanted to avoid taxes. They get in trouble because they misunderstood the rules.
The most common mistakes include:
- Thinking that filing means paying
- Ignoring Colombian bank movements
- Forgetting foreign assets
- Not counting credit card expenses
- Assuming that visa status defines tax residence
- Waiting until August to collect documents
- No actualizar el RUT
- Reporting only Colombian income when worldwide income applies
- Not reviewing rental income from Colombian property
- Filing without checking deductions, exemptions, or withholdings
These mistakes can be avoided with early planning.
At Nexo Legal, we help you review your case before filing so your income tax declaration in Colombia is prepared with clarity and strategy.
Do digital nomads, retirees, and investors need to file?
They might.
Digital nomads, retirees, investors, and foreign property owners often assume they are outside the Colombian tax system because their income comes from abroad.
But that is not always true.
You may need to file if:
- You became a Colombian tax resident
- Your worldwide income or assets exceed the thresholds
- You moved money through Colombian bank accounts
- You bought or own property in Colombia
- You receive rental income from Colombian property
- You operate a business or economic activity in Colombia
- Your purchases or expenses exceeded the legal threshold
This does not automatically mean you will pay tax, but it does mean your situation should be reviewed.
