Taxation of Financial Services under a VAT
探讨增值税应如何对待金融交易，指出简单模型结论存在冲突，主张依据增值税基本目标来设计，原则上金融交易应与其他行业同等征税，但实施存在困难。
In simple economic models, it is relatively easy to describe how to impose a value-added tax at a uniform rate on all consumption goods, and to demonstrate that this tax is equivalent to a proportional labor-income tax, plus a tax on existing assets. The equivalence involves little more than the national income identity relating the sources and uses of income. Once one attempts to incorporate the costs of financial intermediation, however, tax analysis becomes more complicated. In attempting to determine how a VAT should treat financial transactions, various authors have attempted to apply results from simpler models. Unfortunately, these results can lead to conflicting, ambiguous, and misleading prescriptions. In this paper, we argue that one needs to rely more on the fundamental objectives of a VAT to decide how it should treat financial transactions. Adopting this approach, we find that, in principle, the VAT should apply to resources devoted to financial transactions in the same manner that it does in other sectors. However, as discussed below, there are real problems in implementing such a tax on the financial sector which we do not attempt to address in this paper.
