أرى أن هناك خطأ ما في النص بالنسبة لكلمة تجميل

Explanation:


I'm guessing the meaning is adjusting \ reducing the tax base to pay less taxes.

The tax basis of an asset is generally its cost. Determining such cost may require allocations where multiple assets are acquired together. Tax basis may be reduced by allowances for depreciation. Such reduced basis is referred to as the adjusted tax basis. Adjusted tax basis is used in determining gain or loss from disposition of the asset. Tax basis may be relevant in other tax computations.[1]
