What is the fairest tax?

All working people automatically pays, Income tax.. Deducted immediately from their income but VAT is something that most companies pass on to the consumer. Which makes us buyer automatically being double deducted to what you can buy to your take home income. VAT is also somehow good for the country but mostly wrongly used buy Politician (corruption). i also believed that, VAT should be adjusted depending to what is being VATable. If it's for luxury, Sin items and other non-necessary to daily life, then VAt it bigger than those in food, medicine,and ordinary clothing. these should have lower VAT percentage

Fairest is likely the VAT. The problem with the VAT though, is that I can't think of a country which has a VAT, and does NOT have a income tax. The US of course has an income tax. But we do not have a VAT. But no country does not have an income tax, but does have a VAT. So if I have to choose between just paying an income tax, or paying an income tax, and then paying a VAT on all my purchases, I'll take just the income tax.

I think one flat income tax one percentage that all pay.

All taxes seem unfair to somebody. I think income tax is fairly just, except for the boons to the rich politicians have permitted.
