A man asked a preacher friend of mine about a novel, but perhaps unethical, idea for buying a vehicle, but not paying full taxes. Having learned if it, I thought it interesting enough to ask you all.For example, let's say a car is for sale for $10,000. If the sales tax is 10%, that means a $1000 in sales tax. He thought to tell the seller that he would pay $3000 for the truck, but would pay the man $7000 to detail it, deliver it, fill it with gas, etc. This way, the sales tax would only be on the $3000?Is it wrong to seek to shelter money from taxes? Or would this scenario be unethical? No, I am not referring to Donald Trump. This is just something my friend had been questioned about.
