台灣的經濟主要以外銷為導向，近年來因為中國大陸經濟崛起，隨著兩岸經濟的逐漸開放，供應商產業外移，無論傳統產業或高科技產業製造相關企業，西進中國大陸已成台灣產業發展主流，貿易商採用多角貿易進行各種不同商業活動方式早已發展為台灣企業從事國際多角貿易的交易模式，而現行稅務主管機關對傳統外銷之各項租稅規定、法令規範、稽徵程序、實務審核作業規範等，對於台灣產業國際多角貿易類型，產生許多租稅疑義。因此，本論文以問卷調查方法，探討台灣企業從事國際多角貿易面臨之租稅相關議題，以提出改進我國企業從事國際多角貿易之相關租稅規範建議，供政府主管機關參考。 　　本文的問卷結果顯示，國際多角貿易之營業比重在台灣產業已占有舉足輕重之地位，且超過50%受訪企業認為，公司從事國際多角貿易交易與傳統直接外銷，不論在經濟實質、權利義務或風險瑕疵責任歸屬，兩者均相同。有70%以上之受訪企業表示對現行加值型營業稅及營利事業所得稅，在適用上產生困擾。雖然，現行法令對於公司從事國際多角貿易交易收入有銷貨及勞務之區分，但本文的問卷結果顯示有超過80%以上受訪企業認為企業從事國際多角貿易交易的性質係屬銷貨行為，並希望財政部簡化現行對國際多角貿易交易之課稅規範。 　　本論文建議，要健全國際多角貿易課稅規範，消弭國際多角貿易之租稅疑議，首先，必須打破現行課稅法令對國際多角貿易區分由國內出貨或第三地出貨，依出貨地是否在中華民國境內而有不同認定之迷失。其次，對國際多角貿易之會計處理應回歸交易實質，不應藉由課稅之考量來左右會計基礎之入帳原則。最後，財政部應簡化現行對國際多角貿易之課稅規範，減少企業因複雜之課稅規定而將第三地出貨之多角貿易收入規避不列入台灣之營業收入。 / Taiwan's economy is primarily export-oriented. In recent years, because of the rise of economy in mainland China, with cross-strait economy liberalization and relocation of suppliers, both traditional and high technology industry businesses have been moving to mainland China as mainstream of Taiwan's industrial development. Multi-lateral transactions have been adopted by Taiwanese companies in engaging in various international business activities. However, tax laws and regulations, as well as assessment procedures adopted by Taiwan tax authorities, on multi-lateral business have triggered many tax disputes. Therefore, with surveys by questionnaires, this study aims to investigate into the relevant tax issues in the multi-lateral international trade of Taiwanese enterprises and propose suggestions for the tax authorities to improve Taiwan tax treatment on multi-lateral international trade. 　　The questionnaire results show that multi-lateral international trade has become a dominant business model in Taiwan industry, more than 50% of the respondents consider both multi-lateral international trade transactions and the traditional direct export are the same, with respect to economic substance, rights and obligations or liability risks of the transactions. More than 70% of the respondents indicate that they have encountered problems when applying to the existing value-added tax law and business income tax law. Although the existing reguations for companies engaging in multi-lateral international trade transactions classify such transactions into sales and services in their respective tax treatments, the questionnaire results show that more than 80% of the respondents consider such transactions should be all regarded as sales of goods, and urge the Ministry of Finance to simplify the existing taxation on such transactions. 　　This paper proposes the following suggestions to make taxation on multi-lateral international transactions more reasonable and enforceable. First of all, the existing taxation on multi-lateral international trade should not classify such transactions as domestic shipment or third place shipment solely by whether the shipping point is in the territory of Republic of China or not. Second, the accounting for international multi-lateral trade should reflect the substance of such transactions instead of following the tax law treatment. Third, the Ministry of Finance should simplify the existing tax treatment for multi-lateral international trade to prevent Taiwanese enterprises from under-reporting multi-lateral international trade revenues derived from third place shipment in filing Taiwan business income tax because of the complexity of the exitng tax regulations.

隨著知識經濟之發展，無形資產對於企業價值之重要性因而提升。就跨國企業而言，其無形資產配置對利潤分配之影響遠遠超過有形資產之交易，故近年來無形資產已成為各國稅務機關查核跨國企業間移轉訂價之重點項目。 本研究以經濟合作暨發展組織 2013 年7 月30 日發布之「無形資產移轉訂價修訂討論稿」為根基，結合美國、中國及印度等國家之相關規範，分析我國目前對於無形資產移轉訂價規範之缺失，並以近三年來與無形資產移轉訂價相關之國內外訴訟案例為研究範疇，探討實務上徵納雙方常見爭議，進而提出個人建議，冀能做為我國無形資產移轉訂價規範修法方向及徵納實務之參考。 / The importance of intangibles for market capitalization of an enterprise has been rising with the development of knowledge economy. Distributions of intangibles have more impact on profit allocations than transactions of tangible assets for multinational enterprises. As a result, the transfer pricing of intangibles have become the focus of taxation for multinational enterprises. This study analyzes defects of the regulations of transfer pricing involving intangibles in Taiwan based on Revised Discussion Draft on Transfer Pricing Aspects of Intangibles which issued by Organization for Economic Co-operation and Development (OECD) on July 30, 2013 and based on the references of the related regulations in other countries, including United States, China and India. Furthermore, the study analyzes and classifies the controversies of transfer pricing of intangibles between taxpayers and tax authorities in practice for the past three years from the court cases.

庫藏股制度於國外已經行之有年，特別是美國，早在1960年代即有庫藏股交易。我國上市上櫃股票可合法買回自己公司股票制度始於2000年所通過的上市上櫃公司買回本公司股份辦法，除了希望藉以提振東南亞金融危機中不振的股市表現，也賦予企業多一種能向投資人傳遞訊息的管道。本研究基於股票買回的各項假說，希望探究公司股票買回宣告的動機還有事件宣告後對於公司股價的影響效果，最後並檢視公司的宣告決策是否會受到前次購回宣告的表現所影響。 在假說驗證方面，以2000至2004年上市公司832家、上櫃公司236家曾經宣告買回自家股票的公司為研究樣本，輔以選出與買回樣本同時間的相同數量「未買回樣本」，透過1-way ANOVA測試與鑑別分析探討影響公司宣告股票買回的因素符合哪些假說的推論結果。此外，依據各項假說，進ㄧ步利用1-way ANOVA測試和複迴歸分析找出與公司事件宣告後股價異常報酬率之間的關係，接著以1-way ANOVA檢視最後一部份研究主題。經由上述的實證分析，本研究獲得以下主要結論： 1.公司買回自家的股票平均而言對於股價有正面的影響效果。 2.以上市公司而言，影響公司宣告股票買回的假說包括了：自由現金流量假說、個人所得稅節稅假說與財務槓桿假說。以上櫃公司而言則包括：自由現金流量假說、個人所得稅節稅假說與資訊信號假說。 3.以上市公司而言，股票買回宣告後，股價的正向異常報酬與：自由現金流量假說、管理者的誘因假說呈現相關關係。上櫃公司則包括：自由現金流量假說。 4.本次是否再度宣告股票買回會受前次買回的正向累積異常報酬率所影響。 / Stock price reactions on stock repurchase announcements among publicly traded corporations have been widely studied over 40 years in United States. Several hypothesizes were established and provide logical reasons for why corporations buy back their own stocks. References show large proportion of positive effect on post-announcement stock price after stock repurchase announcements from empirical researches. It is since 2000 that corporations are allowed to repurchase their own stocks legally in Taiwan. Although many efforts were put in surveying the post-announcement stock price reactions, few focused on examining how corporations’ repurchase decision would be influenced by different hypothesizes. Moreover, whether or not previous repurchase outcome may affect future repurchase judgments met contradict conclusion from recent studies. This research aims on exploring the two main topics which form 7 hypothesize. Data collecting from Taiwan Economic Journal (TEJ) database, Commercial Times and Economic Daily News contains publicly traded corporations had ever made stock repurchase announcement except financial and government institutions. The period of the study was from Aug. 6, 2000 to Jul. 31, 2004 and total number of announced corporations included was 832 listed on the Taiwan Security Exchange with 236 listed on the OTC separately. Hypothesis 1 to 6 were tested both from individual model using 1-way ANOVA Analysis and integrated model using Discriminate Analysis on Hypothesis 1 to 5, Event Study Analysis on Hypothesis 6. Hypothesis 7 was also verified with 1-way ANOVA Analysis. The empirical results show supports in several hypothesize which reflect corporations did concern free cash flow amount, leverage level, stock underpriced and dividend payout level issues when making repurchase announcement. The stock price after announcement has certain degree of moving correlation toward the same direction as free cash flow level and managerial stockholding level. Finally, previous repurchase outcome was found holding opposite relation with future repurchase judgments.

本文透過比較分析我國收入認列會計準則、現行IFRSs收入認列規定、顧客合約收入草案規定及現行稅務法令規定之差異，對企業在會計及稅務上之影響進行研究分析。研究結果分為兩部分：會計影響方面，在ROC GAAP轉換為IFRSs時有影響者為委託人和代理人之判斷；在IFRSs轉換為顧客合約收入草案時有影響者為信用風險、附退貨權之銷貨、保固、再買回協議、開帳並代管之銷售等五個部分；轉換為IFRSs及顧客合約收入草案時皆有影響者為客戶忠誠計劃、客戶移轉之資產及建造合約三個部分。在稅務影響方面，在ROC GAAP轉換為IFRSs實有影響者為多元要素合約、委託人和代理人之判斷、客戶忠誠計劃、分期付款銷貨、商品或勞務交換、授權費和權利金及客戶移轉之資產七個部分；在IFRSs轉換為顧客合約收入草案時有影響者為信用風險、附退貨權之銷貨及保固；轉換為IFRSs及顧客合約收入草案時皆有影響者為建造合約。 / This study compares the differences between Taiwanese revenue recognition standards, existing IFRSs revenue recognition requirements, IFRS exposure draft “Revenue from contract with customer” and the current tax laws regulation and analyzes the impacts of adopting IFRSs on Taiwanese entities’ accounting and tax practices. The conclusions of this study are divided into two parts. The first part is for accounting. The issue of principal versus agent consideration will have an impact on accounting only when ROC GAAP conversion with IFRSs. The issues of credit risk, sale with a right of return, warranties, repurchase agreements and bill-and-hold arrangements will have impact on accounting only when the exposure draft becomes effective. The issues of customer loyalty program, transfers of assets from customers and construction contracts will have impacts on accounting both when first time adopting IFRSs and subsequently applying the exposure draft. The second part is for taxation. The issues of multiple-element arrangement, principal versus agent consideration, customer loyalty program, installment sales, exchange for goods or services, royalties and transfers of assets from customers will have impacts on taxation only when first-time adopting IFRSs. The issues of credit risk, sale with right of returns and warranties will have impacts on tax only when the exposure draft becomes effective. The issue of construction contracts will have an impact on taxation both when first time adopting IFRSs and subsequently applying the exposure draft.

企業併購法施行將近七年之際，其第四章「租稅措施」共有十條條文，在修法後的解釋適用上卻仍顯困難重重，導致我國企業併購的稅務爭議一直呈現眾說紛紜且矛盾不止的景象。以企業併購為主題的學術論文或坊間書籍，多淪為人云亦云的稅法摘要，未能深入討論併購案中參與之各企業的租稅待遇及對併購公司股東稅負的影響，另外更缺乏國內併購稅務實例的分析介紹，以探求租稅措施各條文之實用性。 基於澄清問題本質，本論文嘗試選取該法第34、38、39、40、41條文，分別從法律形式、文義內容、立法理由、歷史解釋、合憲目的、會計觀點等不同角度分析『租稅減免』、『盈虧互抵』、『免徵營所稅』、『連結稅制』及『跨國併購』等制度細節，並同時討論涉及併購其他稅法的交錯適用，以發掘真正實際困擾所在。研究發現由於我國稅務法規簡陋且錯誤層出不窮，加上行政機關為個案課稅持續發布多種「鋸箭式」的解釋函令，導致租稅制度上之嚴重矛盾，有待修法以重建稅法體系。 雖財政部97/10/17台財稅字第09704552910號函成為企併稅制的里程碑，某些疑慮將蓋棺論定，但離徹底釐清租稅疑慮仍有一大段距離，容易造成無辜企業誤觸（稅法）法網的困擾，反過來熟稔法條之併購公司卻可巧妙運用稅法漏洞，謀求本身最大租稅利益，故本論文以美商案、遠紡案、外銀案及億豐案等國內實例，分別探討重要租稅議題：外國公司在台新設分割能否適用租稅措施？本國公司以土地進行分割應否記存土增稅？外國金控購併本國銀行時如何善用不同交易架構使整體稅負極小化？兩階段購併的不同稅負可否逼迫小股東參與應賣？最後提出建言以期待我國能大步邁向租稅法治國的境界。
