Urgently need to calculate the rebate to the customer, but do not know how to calculate please senior guidance, novice

First of all, your actual offer is 1000 yuan, you should be taxed 1000/1.17*0.17=145.30 yuan

But you reported 1500/1.17*0.17=217.95 yuan

Actually, you got 217.95-145.30=72.65 yuan more VAT

At the same time, you have to generally pay local tax at least 11% (in our case, it may vary from place to place) additional tax

That is 72.65*0.11=8 yuan

So because you overstated the price led to your turnover tax link at least 72.65+8=80.65 yuan of additional tax.

That's not all, because you over-quoted 500/1.17=427.35 yuan of non-taxable income, because your batch of goods regardless of whether to sell 1,000 or 1,500, the turn of the cost is the same, so you also have to bear the 427.35 * 025 = 106.84 yuan of corporate income tax,

So all of the above because of the overquote of more tax produced Total = 80.65 + 106.84 = 187.49

So you give the customer rebate is at least to deduct him 187.49 yuan,

That is, the most return to him 500-187.49 = 312.51 yuan

Understood,, and there is a potential risk
