This article presents the results of a research that aimed at verifying if cities located in the State of Minas Gerais are using the Internet as a means of disclosing financial information. This is recognized as one of the most important ways to communicate the financial information required by the federal law that defines the financial disclosure requirements (LRF), a law aimed at enforcing government accountability and transparency in management. The research was quantitative and based on secondary data collected from the internet. The research was carried out in the webpage of 85 cities randomly selected from a total of 850 cities located in this state. The sample was stratified according to the 12 state regions. It was possible to conclude that most of the cities do not have a proper webpage. However, it was verified that 26.32% of these cities use the services of a private company called Public Administration for Cities (ADPM) in order to publish their financial information. None of the studied cities disclose in their webpages all the information required by the LRF law. The "Summarized Report of Budgetary Execution" is disclosed by 30.94% of the cities, and it is the most common information available. The cities located in the South and Southwestern regions are the ones which presented a more complete disclosure. Conversely, cities located in the West region do not present any information.
