Upside down is when you owe more than the car is worth.

 

No magic formula, I just configured the car in our order system to generate the numbers.

 

The taxable amount is after the trade but before down payment. That would leave cash buyers paying no taxes.

 

How are you able to right off sales tax? Is this a business owned and used vehicle?

 

can some one give me the x plan price on a base gt, ...no options
not including ttt-tax tag title fees.
thanks

 

My understanding is that deducting your trade-in's value from the purchase price before calculating sales tax applies only in a few states (I believe TX is one of them). Last I knew here in CA we have to pay tax on the entire purchase price of the new vehicle regardless of what your trade is worth. The amount of cash you put down is not factored into the sales tax you pay here in CA, and I can't imagine that it would be anywhere.

Here in Northern CA (S.F. Bay Area) our sales tax ranges from 8.25% to 8.75% depending on the county. Car dealers in my area say to add 10% to the sales price of the car to figure what it will be "out the door" with tax and DMV fees. Sales tax in SoCal is generally lower, so adding 9.25% or 9.5% should work there.

Hope this helps.
