Customizing Tax

Broadleaf Commerce can be configured for tax calculation in a number of ways. You can use the simple tax calculator, one of our included third party tax modules (such as CyberSource), or by using a creating a custom tax module.

In this tutorial we will configure the Simple Tax Module for our example company, 'Acme Co' for tax calculation.

Prerequisites

• Broadleaf's Tax Strategy
• [[Broadleaf's Simple Tax Module | Simple Tax Module ]]

Acme Co Tax Requirements

Acme Co has three physical retail locations in the United States: Los Angeles, California, Austin, Texas, and New York City, New York. Each state has its own sales tax rate.

The table below details the locations and their sales tax rate:

Configuring the Simple Tax Module

To customize the simple tax module, simply declare and merge additional tax providers into the blTaxProviders bean within your applicationContext xml. This overrides Broadleaf's out-of-the-box configuration for tax calculation.

Specifying a rate by state will suffice for our needs. Therefore, the property we need to customize in this bean is the itemStateTaxRateMap. For additional properties and their descriptions, see more in the [[Simple Tax Module]] docs.

Here is the complete XML configuration snippet:

<bean id="stateTaxProvider" class="org.broadleafcommerce.core.pricing.service.tax.provider.SimpleTaxProvider">
  <property name="itemStateTaxRateMap">
    <map>
      <entry key="CA" value=".0875" />
      <entry key="TX" value=".0825" />
      <entry key="NY" value=".08875" />
    </map>
  </property>
</bean>
<bean id="customTaxProviders" class="org.springframework.beans.factory.config.ListFactoryBean">
    <property name="sourceList">
        <list>
            <ref bean="stateTaxProvider" />
        </list>
    </property>
</bean>

<bean class="org.broadleafcommerce.common.extensibility.context.merge.LateStageMergeBeanPostProcessor">
    <property name="collectionRef" value="customTaxProviders"/>
    <property name="targetRef" value="blTaxProviders"/>
</bean>

Here is the complete Java configuration snippet:

@Merge("blTaxProviders")
public List<TaxProvider> customTaxProviders() {
    Map<String, Double> itemStateTaxRateMap = new HashMap<>();
    itemStateTaxRateMap.put("CA", .0875);
    itemStateTaxRateMap.put("TX", .0825);
    itemStateTaxRateMap.put("NY", .08875);

    SimpleTaxProvider simpleTaxProvider = new SimpleTaxProvider();
    simpleTaxProvider.setItemStateTaxRateMap(itemStateTaxRateMap);
    return Collections.singletonList(simpleTaxProvider);
}

The changes should take effect on the next server startup. That's it!
