Early buyout of a lease + Selling the car

I have 2 1/2 done on my lease and I'm wondering the following.

I know the buyout price and I have to pay taxes on top of that amount.

What If I find a buyer on the second hand market and I go to the dealership to complete the transaction so that the buyer pays the taxes.

I want to avoid paying the taxes on the buyout and let the buyer pay it. Wondering if this is doable on a car lease.
