I deleted an earlier post when I thought I had answered your question with exact figures…turns out this stuff is more complicated than it looks.
I googled “NY lease tax laws” and this LH post was the first result
Using his formula, I calculated the tax amount to be $2,405.57, or about 10 bucks from the Leasematic sales tax figure (you’ll be able to see how I got there below, but I used a total lease cost of 24,684.15 (Line item 7 below) * (0.00875/(1-0.00875)), as per the formula he provided. You can also see the language he references in Publication 839: A Dealer’s Guide to Sales and Use Taxes on Long-Term Motor Vehicle Leases in New York State on page 17.
I then used my own worksheet to reach an equally close, yet incorrect value of $2,392.35 by calculating the tax as if it were paid upfront, and then adding that up-front tax value back into a new tax calculation in which that tax is capitalized and then taxed again. In both cases, the doc fee is excluded as per the above dealer’s guide. Here’s what I got:
(EDIT: Ignore these figures. Corrections below)
In the relatively simple example @IAC_Scott posted, I’m equally dumbfounded that we cant arrive at the same number, given how few inputs there are here.
Let me know what you guys think.
