Excess Depreciation and the Maximum Tax*
研究发现，对于高工资收入的投资者，加速折旧的优势被大幅削弱，因为超额折旧作为税收优惠项目会触发最高税率惩罚，甚至可能使加速折旧法不如直线法。
The advantages of using an accelerated form of depreciation are significantly reduced for investors with substantial wage incomes. Excess depreciation is treated as a tax preference item under current tax rules which has the effect of imposing significant tax penalties on the high wage income individual who invests in rental property and who qualifies for the maximum tax on personal service income. Under certain circumstances accelerated depreciation methods may be inferior to the straight‐line method. The explanation for this phenomenon lies in the interaction between tax preference income and the maximum tax.
