<GenerationInfo sourceFile="packages/core/src/config/tax/address-based-tax-zone-strategy.ts" sourceLine="39" packageName="@vendure/core" since="3.1.0" />

Address based [TaxZoneStrategy](/current/core/reference/typescript-api/tax/tax-zone-strategy#taxzonestrategy) which tries to find the applicable [Zone](/current/core/reference/typescript-api/entities/zone#zone) based on the
country of the shipping address of the Order.
This is useful for shops that do cross-border B2C orders and use the One-Stop-Shop (OSS) VAT scheme.

Returns the default [Channel](/current/core/reference/typescript-api/entities/channel#channel)'s default tax zone if no applicable zone is found.

:::info

This is configured via `taxOptions.taxZoneStrategy = new AddressBasedTaxZoneStrategy()` in
your VendureConfig.

:::

*Example*

```ts
import { VendureConfig, AddressBasedTaxZoneStrategy } from '@vendure/core';

export const config: VendureConfig = {
  // other options...
  taxOptions: {
    taxZoneStrategy: new AddressBasedTaxZoneStrategy(), // [!code highlight]
  },
};
```

```ts title="Signature"
class AddressBasedTaxZoneStrategy implements TaxZoneStrategy {
    determineTaxZone(ctx: RequestContext, zones: Zone[], channel: Channel, order?: Order) => Zone;
}
```

* Implements: [`TaxZoneStrategy`](/current/core/reference/typescript-api/tax/tax-zone-strategy#taxzonestrategy)
