Apply Tax Rate Based On Location + Order Subtotal ?

Need to collect NYC sales tax from NYC customers. Sales tax is 8.875% for subtotal above $110, sales tax is 0% for subtotals equal to/less than $110.[list]

[]Applying a promotion to offset the NYC tax below $110 doesn't work, because the promotion reduces the subtotal, and then the 8.875% is calculated on the reduced subtotal… which will never match the original sales tax amount.

]The right solution should be applying a different tax rate (of 0%) altogether when subtotal is equal to/less then $110.


Any thoughts?
