Carvana gave me a price $1100 more than my trade.. but the way tax works it ends up being a wash. From what I understand if the Tesla is $53K and my trade value is $13K, only the $40K gets taxed.
If I do a cash down payment instead, the entire $53K gets taxed...
So unless I'm getting at least $2-3K more, it is a wash. Am I correct?
With 3% flat sales tax rate, tax for $53k:
Without trade-in: $53k*3% = $1,590
With trade-in valued @$13k: (53k-13k)*3% = $1,200
So you'd pay $(1,590-1,200)= $390 less tax with trade-in.
Or simpler: you'd pay no tax on the trade-in value part, so $13k*3% = $390 less when trade-in.
In the meantime, you sell your car to Carvana for an extra of $1,100, that's a net gain of $1,100-$390 = $710. So, yep, you'll be $710 ahead by selling to Carvana.
In a nutshell, as long as the extra you'll get from Carvana or whoever other than Tesla is more than 3% of Tesla's trad-in offer, you are ahead.
