一个税收上的术语翻译，小问题

是tax deduction吗？如果是的话：

tax deduction是指在计算出来的income基础上扣减的部分款项用以计算taxable income. 而tax credit则是在就算出来的tax基础上寄予的税收优惠，是已经使用了Tax rate* taxable income的那个结果上抵扣credit，比如一个公司年收入1000，税率10%，deduction是500，credit是3,那么这个公司当年应缴的tax就是
1. Income - deduction deduction = taxable income = 1000-500=500
2. Tax liability = 500 * 10% -3 = 47
