I used it in the last round and assume it works the same. They will just exempt the first $25k from sales tax. You only get the exemption if your purchase price is $45k or less. So if you buy a $40k van you will only pay tax on $15k. This is all done at the dealership when you sign. Might want to confirm with the dealer they are aware of this. When I bought my 2017 they guys there had no idea and didn't even believe the DOR website I showed them at first.
