Cadastral Appraisal vs. Commercial Appraisal in Colombia: Differences, Review, and Taxes (2026)

The 2026 property tax bill arrived and more than one owner almost had a heart attack. With the recent wave of multipurpose cadastre updates promoted by the Government, many Colombians have seen how the official value of their houses and apartments has skyrocketed overnight. If you are thinking of selling, buying, or simply want to understand why you are being charged so much, you need to be clear about the difference between the fiscal value and the actual price of your property.

Quick answer: The cadastral appraisal is an administrative value set by the State (IGAC or local managers) to collect property tax, and by law it must range between 60% and 100% of the commercial value. The commercial appraisal is the real market price of your property, determined by a certified appraiser, and is the figure you should use as a technical reference to sell or request a mortgage loan.

What is the Cadastral Appraisal? (Use and Regulation in Colombia)

The cadastral appraisal is not the price at which you are going to sell your house. It is a mass and administrative estimate made by the Agustin Codazzi Geographic Institute (IGAC) or decentralized cadastral managers (such as Catastro Bogota, Medellin or Cali) with a main purpose: to calculate your property tax.

Watch out for this, because the Law 1450 of 2011 establishes a golden rule: the cadastral appraisal must by law be between 60% and 100% of the commercial value, without ever exceeding it. If the municipality says your house is worth more cadastrally than what someone would pay you for it in real life, they are violating the law.

For this 2026 fiscal year, if your property was not updated or formed during the last year, an automatic adjustment is applied to it. According to Decree 1480 of December 30, 2025, this adjustment is exactly 3% (except for Bogota and other decentralized cadastres that have their own regulations). If you are thinking of buying a farm in Colombia or a rural lot, checking when the last cadastral update was will save you from tax surprises.

What is the Commercial Appraisal and why is it the real value?

Unlike the State's mass calculation, the commercial appraisal is a technical, individual, and detailed market study. It considers your kitchen finishes, the balcony view, the supply and demand in your neighborhood, and the actual state of the structure.

However, an Excel file made by the president of the neighborhood board is not enough. A commercial appraisal only has legal validity (for banks, courts or the DIAN) if it is issued by an appraiser registered and active in the Open Appraiser Registry (RAA), as required by Law 1673 of 2013. Never hire anyone without verifying their registration in raa.org.co.

In the free market, the fees for these professional appraisers usually range between 3.5‰ and 7.5‰ (per thousand) of the total value of the property. Investing in this appraisal is essential if you are going to lease or buy a home through a mortgage loan.

Legal Caps on Property Tax in 2026 (Protection for the Owner)

The fact that your cadastral appraisal doubled after an IGAC update does not mean that your property tax will double. The Law 1995 of 2019 acts as a protective shield for the pockets of Colombians, setting strict limits on what they can charge you from one year to the next.

For the year 2026, the legal increase caps are as follows:

• Updated properties: The maximum increase cap is the CPI of the previous year plus 8 percentage points. Since the 2025 CPI closed at 5.10%, the maximum increase for your property tax in 2026 will be 13.10%.
• Non-updated properties: The increase limit is a maximum of 50% with respect to the amount settled the previous year.
• Strata 1 and 2 housing: If the appraisal is less than 135 SMMLV (that is, $236,372,175 COP with the 2026 minimum wage set at $1,750,905), the maximum increase will be exactly equal to inflation (5.10%).

If you notice that your bill exceeds these percentages, I recommend reading our guide on the property tax in Colombia to understand the specific rates for your municipal council.

Step by Step: How to Request a Review of your Cadastral Appraisal before the IGAC

If you have solid proof that the cadastral value exceeds the commercial value of your property, or if you are being charged for built square meters that do not exist, you can defend yourself. The procedure is free and is done through the IGAC Virtual Window VIVI (vivi.igac.gov.co) or in person at your cadastral manager.

1. File the Review Request: According to Resolution 1040 of 2023 (modified by Resolution 746 of 2024), you must present technical evidence (photos, plans, or ideally, a commercial appraisal from the RAA).
2. Wait for the resolution: For the competent cadastral manager under these resolutions, the maximum time to resolve a review request in depth is 3 months counted from the successful filing. If your municipality has a decentralized manager, confirm their own channel and procedure.
3. Self-estimation Option: You have the legal right to present a justified cadastral self-estimation. Be careful with the date: this procedure expires on June 30 of each year.

An honest piece of advice: Do not file a complaint saying "it seems too expensive to me". If you do not attach technical evidence that the value exceeds 100% of the commercial value or that there is an area error, they will reject your request or, worse still, if they send an inspector and discover improvements that you had not declared, they could raise the appraisal even further.

Do you want to sell or lease your property? Forget about the cadastre

One of the most serious financial mistakes owners make in Colombia is trying to sell their house based on the cadastral appraisal or on "what they were told it was worth". The market is driven by real supply and demand, not by tax decrees.

To give you an idea of the current opportunity: according to the active ads on Colombia Move (July 2026), the housing section records more than 16,000 demand views against only 91 active ads. There is a huge deficit of properties published at real market prices, which means that buyers are waiting but cannot find options without intermediaries.

The cadastral appraisal is a mass administrative value used by the State to charge property tax, while the commercial appraisal is a specific technical study that calculates the actual selling price of the property in the free real estate market.

❓ How much can my property tax increase in Colombia in 2026?

By law, the increase in your property tax in 2026 cannot be infinite: it has a cap of 13.10% (2025 CPI + 8%) if your area was recently updated, or a maximum of 50% of what was paid the previous year if your area does not have a current cadastral update.

❓ What is the automatic readjustment of cadastral appraisals for 2026?

In accordance with Decree 1480 of December 30, 2025, the automatic readjustment for urban and rural properties not updated or formed in 2025 is 3% starting January 1, 2026. This standard adjustment does not apply to Bogotá or decentralized municipal cadastres that have their own provisions.

Self-estimation is the legal right that every owner has to submit in writing their own estimate of the value of their property supported by technical evidence. The deadline to file this request with the respective cadastral manager expires unfailingly on June 30 of each year.
