The creation of the Brazilian Real Estate Registry (Cadastro Imobiliário Brasileiro – CIB) also intersects with municipal taxation, particularly the IPTU. By bringing together, in a national system, information that is currently scattered across city governments, notary offices and other agencies, the registry is expected to improve the data base used by municipalities to levy the tax, reducing registration inconsistencies and strengthening oversight. 

In practice, consolidating this information may allow for more accurate updates to the General Property Value Map (PGV) and help identify undervalued properties or those without proper registration, which could affect IPTU revenue. Although Brazil’s Federal Revenue Service states that the CIB does not create new taxes, data integration reinforces the registry’s role as an indirect tool supporting local tax policy. 

Using data from SiiLA’s Market Analytics platform, based on Class A+, A and B office buildings in São Paulo, it is possible to rank the areas with the highest IPTU values per square meter. 

The highest IPTU values in São Paulo are found in CBD areas. Faria Lima tops the ranking at R$19.88 per square meter, followed by JK at R$18.44 per square meter and Paulista at R$17.27 per square meter. For comparison purposes, the non-CBD area with the highest IPTU value is Moema, at R$13.73 per square meter. In the overall ranking, the area places eighth. 

As a result, the areas with the highest IPTU values also tend to concentrate the highest market values for real estate. In Faria Lima, for example, in addition to having the most expensive IPTU, the region also posts the city’s highest price per square meter, at R$237.87. 

However, the market value ranking does not exactly mirror the IPTU ranking. Berrini, for instance, has the third-highest IPTU in São Paulo, but ranks only tenth in terms of market value, at R$79.22 per square meter.
