The objective of this study is to check compliance of the depreciation rates used by the companies, in conformity with the explanatory notes of property, plant and equipment included in their annual reports, with the concept of depreciation described in the Accounting Theory. The depreciation rates suggested by the Brazilian income tax regulation were utilized to compare the depreciation rates used in the balance sheets published. Based on this objective, three questions were raised: (i) is the accounting standard effective in Brazil, as regards depreciation rate, in accordance with the Accounting Theory?; (ii) is the accounting practice followed by the companies, with regard to depreciation rate, consistent with the definitions of the standard?; and (iii) did the new accounting legislation lead to the adoption of depreciation rates different from those recommended by the Tax Authorities? In order to obtain answers to the questions above, three hypotheses were corroborated, namely: (i) I the Brazilian accounting standard is in conformity with the Accounting Theory as regards the concepts of useful life of assets; (ii) II assets submitted to different conditions and systems to explore their benefits will have various economic useful lives. However, in hypothesis III, it is expected that, according to hypotheses I and II, and considering the definition of useful life of assets given by the Accounting Theory, the depreciation rates used be determined in accordance with the useful life of the asset and, therefore, be different, depending on their use and lines of business. Accordingly, for the same asset different depreciation rates will be used in different businesses, which means that not always the depreciation suggested by the Tax Authorities can be adopted as a rule. That hypothesis was refuted, based on the empirical surveys. The research adopted three methods to obtain the necessary information and data: (i) bibliographic research for the theoretical basis; (ii) documental research for surveying the standards in effect; and (iii) empirical research for surveying the data in primary sources
