The IFRS adoption in Brazil impacted not only the consolidated financial statements, but also the individual local financials, normally used for the income taxes calculation. The objective of this research is to analyze the effect of the international accounting standards adoption in the linkage of financial accounting and tax accounting, in order to verify if there is a greater gap between the accounting and tax rules after international accounting standards. Therefore, three periods regarded as regulatory frameworks are analyzed: 2007, between 2008 and 2013 and from 2014. There are insights in the literature presenting that the introduction of international accounting standards causes a greater gap between the financial accounting and taxation. However, recent changes in accounting and tax rules in Brazil have not been addressed in other study, which motivated this review. Thus, based on the model, which allows assess the main accounting items in a systematic way, developed by Lamb et al. (1998), some modification of the model to the Brazilian contemporary reality is made. Hence, the major identified accounting topics are explored from a bibliographic and documentary research, especially involving accounting and tax rules aspects in the three periods aforementioned. Based on this, the analysis is followed by the classification of each accounting topic in one of the five cases used in the model of Lamb et al. (1998) to assess the level of the link with accounting and taxation. After this classification, the number of cases that suggested a close accounting and tax relationship is compared with those who had disconnected standards, and therefore a gap in the link and the result of the comparison of the cases in the three periods attends as foundation to answer the proposed research question. It is found that the accounting and taxation linkage in Brazil decreased with the international accounting standards, introduction even after the tax accounting regulation of the international accounting standards adjustments. The results present a development in the link between accounting and taxation during, at least, for the last eight years, which contribute to academic studies in financial and tax accounting. Moreover it shows the Brazilian approach, which represents one of few countries where the taxation rules has been adjusted by the international accounting standards.
