碩士 === 國立政治大學 === 會計研究所 === 91 === XBRL is an XML-based, royalty-free, and open standard, used to stipulate the data exchange standard in the Internet. XBRL can substantially help improve the transparency of financial information, and communicate the information chain more fluently, and expedite the data processing. The objective of this thesis is to establish the XBRL taxonomy for the returns of Business Income Tax in Taiwan, and to design the XBRL-based application software for filing the Business Income Tax returns. By establishing the XBRL taxonomy, it can help the tax department to retrieve tax return data from corporations more efficiently. Since the data for filing tax returns can also be retrieved directly from the general ledger database, the benefits of promoting the XBRL-based tax return filing system would include saving operation costs, reducing the possibility of errors, avoiding re-keying data, and filing tax returns faster and more efficiently. For the National Tax Administration, the XBRL-based filing system can simplify the paper work on processing tax returns. Further, National Tax Administration can utilize the program to directly analyze the electronic tax data, diagnosing the abnormal financial relationships, and devise more efficient audit program. In the future, if the data of corporations’ general ledger and business tax are all prepared in XBRL, National Tax Administration can directly trace from tax return data to firms’ financial statements and thus increase the efficiency and effectiveness of tax audit. To facilitate building the XBRL-based tax return filing system, this thesis establishes a set of XBRL taxonomy for Business Income Tax return in Taiwan, and use the taxonomy to design a XBRL-based application software for Business Income Tax returns. This thesis also demonstrates the application of this software using virtual financial data to generate the XBRL-format Business Income Tax return data. Further, this study also designs a software that can be used by National Tax Administration to verify the tax return data received from corporate taxpayers.
