Illinois taxes the sum of the base payments plus, levies tax on cash cap reductions as well as rebates. I’m assuming all taxable fees (e.g., acquisition fee, dealer doc fee) are capped in the base payment. Your money factor doesn’t look right. Are you sure it isn’t 0.00206?
You have a lot of information missing (e.g., adjusted cap cost, cap reductions, acquisition fee, doc fee, term). What fees are you capping in the lease? What is the total cap reduction, if any? What fees are you paying upfront?
