Clean Property Record, Hidden Risk: Buying Real Estate in the Face of Tax Debt and Fraud Against Tax Enforcement

The purchase of real estate is usually associated with the analysis of the property record. Indeed, the real estate registry record is the main document for identifying the property, its owners, annotations, liens, attachments, mortgages, fiduciary alienations, usufructs, restrictions on disposal, and other formally registered encumbrances.
However, there are situations in which an apparently clean property record does not eliminate all risks involved in the acquisition.
One of the most sensitive issues, especially in transactions involving business owners, family companies, individual entrepreneurs, companies in financial distress, or individuals with a relevant history of economic activity, is the existence of tax debts enrolled as active debt.
The subject has gained particular relevance with recent decisions of the Superior Court of Justice, which reaffirm the strength of article 185 of the National Tax Code in the context of fraud against tax enforcement.
The problem: the property record may not reveal the entire risk
In many real estate transactions, the buyer limits due diligence to obtaining an updated property record and, at most, checking a few basic certificates related to the seller.
Although this procedure is important, it may be insufficient.
The property record may show no attachment, restriction on disposal, premonitory annotation, or any entry indicating the existence of a tax enforcement proceeding. Even so, if the seller already had a tax debt duly enrolled as active debt before the sale, the transaction may later be challenged by the Public Treasury.
In other words: the property may appear to be free and clear in the real estate registry, but still be legally exposed due to the seller’s tax situation.
This is the so-called hidden tax risk.
Fraud against tax enforcement has its own legal regime
In ordinary civil proceedings, fraud against enforcement usually requires stronger evidence that the third-party buyer had knowledge of the claim or that there was a registered encumbrance over the asset. For this reason, in many situations, the buyer’s good faith plays a relevant role.
In tax matters, however, the logic is stricter.
Article 185 of the National Tax Code presumes fraudulent the sale or encumbrance of assets carried out by a taxpayer who owes the Public Treasury a tax debt duly enrolled as active debt, unless sufficient assets or income have been reserved to pay the debt.
After the amendment introduced by Supplementary Law No. 118/2005, the understanding became consolidated that, in sales carried out after June 9, 2005, the enrollment of the tax credit as active debt before the sale is enough to establish the presumption of fraud against tax enforcement.
This means that the discussion is not limited to the existence of an attachment recorded in the property record. The focus shifts to the seller’s tax situation at the time of the sale.
The buyer’s good faith: important, but not always sufficient
One of the issues that creates the greatest insecurity in this type of transaction is the following question: if the buyer acted in good faith, paid the price, executed the deed, and registered the property, can the buyer still be harmed?
In certain cases, yes.
The Superior Court of Justice has held that, in tax enforcement proceedings, the sale of assets after the enrollment of the tax credit as active debt constitutes fraud against enforcement by absolute presumption, regardless of proof of bad faith by the third-party buyer.
In these cases, STJ Precedent No. 375, according to which the recognition of fraud against enforcement depends on the registration of the attachment or proof of bad faith by the third-party buyer, does not apply in the same way to tax enforcement proceedings.
The reason is that tax credits are governed by a specific legal regime, with a specific rule set forth in the National Tax Code.
Therefore, the buyer’s subjective good faith, although relevant from a transactional and evidentiary standpoint, may not be sufficient to prevent the recognition of fraud against tax enforcement when the sale occurred after enrollment as active debt and the debtor did not reserve sufficient assets to satisfy the debt.
The risk increases in transactions involving individual entrepreneurs
The problem becomes even more delicate when the seller is, or has been, an individual entrepreneur.
In the case of an individual entrepreneur, there is no full separation of assets between the individual and the business activity. The CNPJ serves as the tax identification of the activity, but the holder’s personal assets may answer for obligations related to the business.
Thus, even if the debt is linked to the individual entrepreneur’s CNPJ, there may be discussion regarding the personal patrimonial liability of the individual and the validity of the sale of real estate owned by that person.
This point is especially relevant in transactions in which the seller appears in the property record as an individual but has, or had, an individual business with significant tax debts.
For the buyer, the risk is clear: analyzing only the seller’s CPF may not reveal the entire tax liability connected to the seller’s business activity.
The concentration of acts in the property record does not eliminate tax due diligence
In recent years, Brazilian legislation has reinforced the importance of the principle of concentration of acts in the property record. In general terms, this principle seeks to provide greater security to real estate transactions, allowing third parties to rely on the information contained in the registry.
However, this protection should not be understood as absolute.
In tax matters, case law has recognized that the absence of an annotation in the property record does not, by itself, prevent the recognition of fraud against enforcement when the requirements of article 185 of the National Tax Code are met.
This is why it is important to understand that a clean property record is not synonymous with a safe transaction.
The property record is the starting point, not the final point of the analysis.
What should be observed before the purchase
The acquisition of real estate requires documentary analysis proportional to the value of the asset, the nature of the transaction, and the profile of the parties involved.
In more significant transactions, especially when the seller is a business owner, company partner, manager, rural producer, developer, builder, individual entrepreneur, or person with a history of intense commercial activity, caution must be expanded.
It is not enough to verify whether there is an attachment registered against the property. It is necessary to assess the seller’s tax situation, the seller’s relationship with companies, any debts enrolled as active debt, ongoing tax enforcement proceedings, protests, pending lawsuits, state, municipal, and federal certificates, as well as other signs of insolvency or patrimonial risk.
It is also important to verify whether, even if debts exist, the seller retains sufficient assets to satisfy tax obligations. This information may be decisive for the risk analysis.
Each case requires its own assessment. A simple purchase between private individuals is not the same as the acquisition of a property owned by an individual entrepreneur, a company in crisis, a family business group, or a person involved in tax enforcement proceedings.
A low price may be a warning sign
Another element that deserves attention is the transaction price.
Very substantial discounts, unusual urgency to sign, resistance to providing certificates, a history of debts, successive transfers of the property, or a sale carried out shortly after financial or tax difficulties may indicate a risk of future challenge.
The buyer should not analyze only the property. The buyer should also analyze the seller.
In contemporary real estate law, the risk is not always in the property record. Many times, it lies in the person selling the property.
The security of the purchase depends on a preventive strategy
Buying real estate is one of the most relevant patrimonial transactions for individuals and companies. Therefore, legal prevention must come before payment of the price, execution of the deed, and registration.
Once the transaction is challenged in court, the problem ceases to be preventive and becomes contentious. The buyer may have to defend the acquisition through third-party claims, discuss fraud against enforcement, demonstrate the precautions taken, face freezes, attachments, or even the risk of losing the effectiveness of the purchase in relation to the Tax Authorities.
Real estate due diligence should not be seen as a bureaucratic formality. It is an instrument of patrimonial protection.
Conclusion
A clean property record remains essential, but it is not enough.
In real estate transactions, especially when the sellers are business owners, individual entrepreneurs, partners, managers, or persons with possible tax exposure, it is indispensable to investigate the seller’s tax and patrimonial risk as well.
The existence of active debt prior to the sale may turn an apparently safe acquisition into complex litigation, even if the buyer acted without any intent to commit fraud.
The central point is simple: in the real estate market, those who buy by looking only at the property may fail to see the true risk of the transaction.
Legal certainty lies in a complete, preventive, and strategic analysis of the deal.
