Tiered US Taxation

Tiered taxes are tax rates or tax fees that differ based on the total transaction unit amount or price. When a US tax has a rate change based on the total price, more than one tax tier can apply in a single transaction. Tiers can be based on a base charge, for example, $0-$10, $10-$20.

The revenue amount used for a specific tiered rate is called a tax base, and tiered taxes can be defined based on the minimum and maximum tax base. Some tiered taxes are based on the revenue amount of one transaction, and some are based on the monthly revenue amount. MATRIXX Engine keeps track of these as needed.

Tiered fees are values that change based on the number of items purchased. Tiered taxes can be based on a unit with a split aggregation or a unit with a spread aggregation. A split aggregation takes the fee, the minimum and maximum unit type, the tax rate, and the minimum and maximum tax base values and applies them in order. A spread aggregation determines which tier applies to the total calculated amount (either sales price or unit volume, or any applicable combination of the two), and applies only the values in that tier to the entire amount; the single tier applies to the whole transaction.
