This study is to determine the performance of regional financial ratios in the Labuhan Batu District and whether there is transparency in financial statements managed by the local government. According to financial accounting standards, financial statements are part of financial reporting. Complete financial statements usually include balance sheets, income statements, and statements of changes in financial position, as well as explanatory materials that are an integral part of financial statements; the purpose of this study is to measure and analyze the degree of fiscal Decentralization in Labuhan Batu District during 2015 to 2020 as well as analyze the relationship of Gross Domestic Product (GDP) with the level of fiscal Decentralization during the same period. GDP is one of the methods for calculating national income. Documentation techniques carry out data collection. The data analysis technique used is a financial statement analysis technique based on the budget realization report from 2015 to 2020. The results of the study show that the level of regional authority and responsibility in implementing decentralization, which is related to regional development is at a moderate level, this is because the amount of original local government revenue is still relatively small compared to the total regional income, still very dependent on financial assistance from the central government/ external parties.
