### taxZoneStrategy

\<MemberInfo kind="property" type={`<a href='/current/core/reference/typescript-api/tax/tax-zone-strategy#taxzonestrategy'>TaxZoneStrategy</a>`} default={`<a href='/current/core/reference/typescript-api/tax/default-tax-zone-strategy#defaulttaxzonestrategy'>DefaultTaxZoneStrategy</a>`}   />

Defines the strategy used to determine the applicable Zone used in tax calculations.

### taxLineCalculationStrategy

\<MemberInfo kind="property" type={`<a href='/current/core/reference/typescript-api/tax/tax-line-calculation-strategy#taxlinecalculationstrategy'>TaxLineCalculationStrategy</a>`} default={`<a href='/current/core/reference/typescript-api/tax/default-tax-line-calculation-strategy#defaulttaxlinecalculationstrategy'>DefaultTaxLineCalculationStrategy</a>`}   />

Defines the strategy used to calculate the TaxLines added to OrderItems.

### orderTaxCalculationStrategy

\<MemberInfo kind="property" type={`<a href='/current/core/reference/typescript-api/tax/order-tax-calculation-strategy#ordertaxcalculationstrategy'>OrderTaxCalculationStrategy</a>`} default={`<a href='/current/core/reference/typescript-api/tax/order-tax-calculation-strategy#defaultordertaxcalculationstrategy'>DefaultOrderTaxCalculationStrategy</a>`}  since="3.6.0"  />

Defines how order-level tax totals and the tax summary are calculated.

The default strategy rounds tax at the individual line level and then sums
(per-line rounding). The [OrderLevelTaxCalculationStrategy](/current/core/reference/typescript-api/tax/order-tax-calculation-strategy#orderleveltaxcalculationstrategy) alternative
groups net subtotals by tax rate and rounds once per group (per-total rounding),
which is required by certain jurisdictions and ERP systems.
