基於XBRL格式在企業報告資訊上的優勢，全球各重要經濟體近年來陸續應用XBRL技術進行財報格式的轉換與標準化，而在推動XBRL實務發展的過程中，XBRL分類標準的建置為核心關鍵因素。各國於制訂分類標準基於成本效益考量，分類標準內容通常僅涵蓋企業報告之通用元素，企業若僅按分類標準編製報告，可能導致有用訊息之喪失。以XBRL格式作為申報工具時，企業若基於自願性揭露及報告之完整性，則必須對分類標準自行進行延伸。本研究藉由美國分類標準延伸情況作為借鏡，探討台灣未來開放分類標準延伸時，如何進行分類標準之延伸及其規則和方法。 / Considering the advantages of XBRL-formatted information in business reports, many major global economic leagues have adopted XBRL technology in financial reports’ transformation or standardization. XBRL Taxonomy development is the core factor in promoting XBRL into practice. Taking cost-benefit analysis into account, competent authorities usually design their taxonomy with only basic elements used in business reports. If enterprises prepare their reports just based on the taxonomy, they may lose some useful information. Therefore, they must extend taxonomy to make a voluntary disclosure when enterprises file their reports in XBRL-formatted. This research explores the rules and methods of taxonomy extensions for TIFRS Taxonomy by referring to how companies in the U.S. make taxonomy extensions.

XBRL是一種以XML為基礎所發展出來的一種語言，用來規範網路財務資訊揭露而產生的資料交換標準，同時也是提升財務資訊透明化的推手。XBRL使資訊可以更快速地流通，改善資訊處理的速度。 本論文的研究目的，在於透過XBRL之應用，來建立公司營利事業所得稅申報書之各個項目的分類標準，並設計一套以XBRL為基礎之營利事業所得稅申報系統。就營利事業而言，XBRL可以協助企業稅務部門取得資料，讓營利事業所得稅申報上所需的部份資料，可以直接從總帳資料庫轉入產生，讓企業在稅務資料處理上可以減少作業成本，降低人為錯誤的可能性，減少重覆手動輸入資料，讓報稅工作更為快速、有效率，透過網路傳輸報稅檔案，節省了報稅人在報稅期間必須親自稅捐稽徵機關排隊等待報稅的時間。就稅捐稽徵機關而言，所有的企業按同一套XBRL標準來報稅，可簡化稅務處理工作，更者，可將取得之資料進行分析，找出異常並加以審查，且若未來XBRL能順利推廣，營利事業之總帳系統與申報營業稅之資料均以XBRL編製而成，則因為所有檔案型態一致，稅捐稽徵機關在進行調帳查閱時，可以大大減少查核的人力及成本，可以增加查核的效率。 本論文將建立起一套符合中華民國稅法與相關法令規定之營利事業所得稅之XBRL 分類標準，並利用該分類標準之架構，設計出一套能符合現行法令規定且以XBRL為基礎之營利事業所得稅申報之程式軟體。本論文會將虛擬資料輸入已建好之程式，來進行實際展示如何產生以XBRL為格式之營利事業所得稅申報電子檔，以作為未來企業運用時之參考。另外，針對國稅局方面，本論文亦設計一驗證程式，讓國稅局能夠對所收到之營利事業所得稅申報檔進行資料正確性之檢查及驗證。 / 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 abcdrmal 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.

摘要 在投資風險的考量下，合併財務報表能提供投資者完整的企業資訊。而合併財務報表的編製，並未隨著資訊科技的發展，仍多仰賴人工編製。可延伸企業報導語言（XBRL）的興起，提供企業一個揭露財務資訊的標準化規範，XBRL規範標準第二版利用可延伸連結語言（XLink）與可延伸路徑語言（XPath），進行科目元素間關連與處理規則的定義，更加了提升XBRL財務報導的彈性，並更利於延伸之應用。 本研究即根據XBRL規範標準第二版，利用XBRL合併財務報表分類標準套件之建立，進行XBRL合併財務報表的自動化編製，並提供XBRL合併財務報表，提升XBRL財務報導之資訊內涵。 本研究首先根據我國財務會計準則公報第七號「合併財務報表」之購買法處理規定，轉化編製準則為「標準等式」以利分類標準之建立與程式之撰寫。根據「標準等式」，進行資訊分類後，本研究依序建立「合併報表編製資訊分類標準架構」與「XBRL合併財務報表分類標準套件」。前者之目的在提供企業進行內部會計資訊的對應(Mapping)，並將合併報表編製所需之所有資訊，轉換為XBRL格式，以利合併報表自動化編製之進行。而「XBRL合併財務報表分類標準套件」則是利用XBRL連結庫與規則庫的規範，進行合併報表編製準則的描述，以利系統之開發。在完成分類標準的建立之後，本研究以一合併報表編製範例，並利用JAVA程式語言，實作合併報表範例編製系統，以驗證本研究建立之分類標準之可行性。 根據本研究實作範例系統之結果，不僅可以自動化編製XBRL合併財務報表，本研究利用XBRL規則庫進行編製準則之描述，亦提昇合併報表編製系統處理邏輯的正確性與維護便利性。此外，本研究擴充了XBRL之應用範圍，而不限於傳統之財務資訊分析，相關之會計領域問題，皆可利用本研究所建立之架構進行應用。 / Abstract Under the consideration of risk, consolidated reports provide a whole picture of a business entity. As the information age comes, consolidate reports are still prepared by hand. Extensible Business Reporting Language (XBRL) provides a standard format for business to disclose their financial information. The specification version 2.0 of XBRL, in which XML Linking Language (XLink) and XML Path Language (XPath) were adopted to define the relationships and processing rules of XBRL elements, increases the flexibility of XBRL reporting and provides an advantage to the development of XBRL application. This study, on the basis of specification version 2.0, focuses on the computerized preparation of consolidated financial reports by building up the “XBRL Consolidated Reports Taxonomy Package.” In addition to general XBRL-based financial information, business is also capable to disclose XBRL-based consolidated reports with this taxonomy package. Firstly, This study converts the accounting standards of purchase method defined by ROC statement of financial accounting standard no.7: “Consolidated Financial Reports” to several “Standard Formula” in order to build the taxonomies and implement the prototype system. After classifying the information of the standard formulae, this study creates the “Consolidated Reports Preparation Information Taxonomy Framework”, which provides a basis for business to map their internal chart of accounts. As the information mapping was done, business transfers all information (needed by preparation) to XBRL documents. After creating the framework, “XBRL Consolidated Financial Reports Taxonomy Package” was built up. According to the “XBRL Link Base” and “XBRL Rule Base”, this taxonomy package addresses the accounting standard of consolidated reports in the form of XBRL (XML) document. At last, this study gives a consolidating example and implements a prototype system by JAVA to verify the feasibility of the taxonomies created in this study. Based on the implementation of the prototype system, it is not only capable to prepare XBRL consolidated reports automatically but enhances the accuracy of the processing logic and the convenience to maintain the system in compliance with XBRL rule base. Moreover, this study extends the application area of XBRL, which focused on traditional financial information analysis. The structure of this study will be suitable for other accounting issues.

集團財務資訊的編制在企業資源規劃系統的協助下，產生的速度已較以往大為增快許多，然而，先不論相關系統的訓練、導入、維護及更新成本，目前的財務資訊仍舊需要多次的輸入、分發及反覆檢覈，這些步驟尚停在人工編製的階段。 XBRL（可延伸企業報告語言，eXtensible Business Reporting Language）的發展，使企業打破傳統財報的表單形式，它利用電腦可讀的標籤語言減少大量的傳統人力編製流程。後來更發展了財務報告的分類標準（以下簡稱XBRL FR），用來表達財務報表合計性的資訊，但這些處理過的加總數字，無法再還原為原始資料，故對於各國會計準則無法自動轉換，對於跨國公司的合併財務資訊依舊費時費力。 本研究首先依據國際會計準則委員會、臺灣、中國及美國官方所制定的XBRL FR進行分析及比較，建立一個新的XBRL FR，稱為NCCU XBRL FR，蒐集一般行業編制集團財務資訊之必要明細科目（僅包含所有流動資產和流動負債）。接者透過「對應標籤(mapping tags)」的技術，設計一邏輯規則庫，內建四種NCCU XBRL FR分別對應四地XBRL FR之「XBRL計算連結庫(XBRL Calculation Linkbase)」，即可自動轉換NCCU XBRL FR和四地XBRL FR的資訊。最後利用四地之原本XBRL FR計算連結庫，計算編製合併報表資訊前的個別報表資訊。 本研究提出多國準則探討及XBRL FR對應的方法，設計問卷並執行國內四大事務所之專家訪談，發現各國財務報表準則仍然受到會計專業的主觀判斷而分歧，未來全球財報共通的目標，還有很長的一段路要走。 / Because of the support of Enterprise Resource Planning system, business groups speed up their financial reporting preparation. Leaving aside the system cost of training, implemention, maintenance and update, its financial information still requires multiple inputs and distributions currently, and needs to repeatedly check their validity. These steps still remain at manual labor. XBRL (eXtensible Business Reporting Language) helps business to break the form of traditional financial reporting. It has machine-readable label tags, and it can reduce lots of traditional manual process. Financial Reporting Taxonomies (hereinafter referred to as XBRL FR) now are used to express the information of the total amount in financial statements. Because processed numbers can not revert to the original data, accounting principles adopted by nations around the world cannot switch amid different principles. Therefore consolidations of financial information still cost multinationals a lot of resources. In this study, based on analysis and comparison of International Accounting Standards Board, Taiwan, China and the United States official XBRL FR, we established a new XBRL FR, called NCCU XBRL FR, which is used to collect general commercial and industrial financial information (including only current assets and current liabilities). Then, we use mapping tags technology to design some logic rule database, which has four built-in XBRL Calculation Linkbases corresponding to four XBRL FRs. The logic rule database can automatically convert NCCU XBRL FR to four XBRL FRs. Ultimately, the original four XBRL FR Calculation Linkbases can compute individual financial statements before preparation of consolidated information. In this study, we proposed a method of multinational accounting standard discussion and XBRL FR mapping. We designed the questionnaire and conduct in-depth interviews to the experts of Big 4 audit firms. Then we found that there are differences in subjective judgments of multinational accounting standard. In the future, there will be a long way to go if we have the goal of common global financial reporting.
