This can be a helpful jumping off point as you plan your implementation. ## Create a new tax group for back-to-school items Many jurisdictions implement back-to-school sales tax holidays before the start of the school year. During these periods certain school supplies, clothing and electronics are exempt from sales tax. Create a tax group to categorize these items: 1. Call [Create Tax Group](https://dev.wix.com/docs/rest/business-solutions/e-commerce/tax/tax-groups/create-tax-group.md) to create and name a new tax group. Save the `id` that is returned. Note that each tax group is calculated based on the [tax region](https://dev.wix.com/docs/rest/business-solutions/e-commerce/tax/tax-regions/introduction.md), if the tax group is treated differently based on the region then a unique group should be created for each region. 2. Call [Update Product](https://dev.wix.com/docs/rest/business-solutions/stores/catalog/update-product.md) to update the `taxGroupId` field for the relevant products in your catalog. When a tax group is no longer needed, such as when the seasonal status no longer applies, [delete](https://dev.wix.com/docs/rest/business-solutions/e-commerce/tax/tax-groups/delete-tax-group.md) the group. The default tax group for that catalog will apply to any products that have the deleted `taxGroupId`.
