Sale of 100,000, VAT = 100,000/1.17*0.17 = 14,529.91 (14,500)
If the input price of the 100,000 goods is 80,000, it can be included in the cost of goods sold and deducted before income tax.
If you don't make a VAT sale of 100,000, the cost won't be deductible before tax. The accounting needs to match.
Profit = (100k - 80k) = 2
Income tax = 2*25% = 0.5k
Taxable cost = 1.45 + 0.5 = 1.95
If you're going to look for a ticket, you need to look for at least 80k in order to match the VAT you're paying. So it's best to pay the VAT and then charge the tickets etc to period expenses so you can pay less income tax.
