What this means for your lease
In plain English: tax on the total of all payments is collected up front. South Dakota's state-level lease sales-tax rate is 4.00% (before any local add-on).
Your cap-cost reduction (cash down, trade equity, or rebates applied as a down payment) IS taxed in South Dakota, so putting more cash down does not escape the tax.
The detail
Long-term leases (more than 28 days) are subject to the 4% motor vehicle EXCISE tax (not general sales tax). The taxable base is the total of all lease payments plus down payment, lease fees and incentives, minus trade-in — i.e., tax on the total of payments. Down payment / cap-cost reduction IS included in the taxable base. Short-term leases/rentals (28 days or less) are exempt from the excise tax but subject to state + municipal sales tax (and possibly tourism/gross-receipts tax).
Local add-ons
Municipal sales tax (commonly 2%) can apply to short-term (<=28 day) rentals; the 4% motor vehicle excise tax on long-term leases is a flat state tax with no municipal add-on. SD raised the motor vehicle excise rate context-wise stays at 4%.
