Using Tax Overrides for Multiple Address Checkouts 📦
If your store requires specific tax rules for particular products that can not be calculated automatically based on the values set in your tax settings, or through Giftship’s TaxJar integration, you will need to configure tax overrides in order to handle these special tax rates.
***Please note – this article does not describe how to add tax override rules for single address checkouts.
Some code installation in your theme is required in order to allow for your products tags to be read by Giftship. First, navigate to your product form template in the Shopify Theme editor, by going to Shopify Admin -> Online Store -> “Your Theme Name” -> Actions -> Edit Code, and find your product form template. On the “Debut” Shopify theme, this is found in the Sections -> product-template.liquid file.
Right beneath the opening product form liquid tag, paste the below code:
{% assign tagLength = product.tags | size %} {% if product.tags and tagLength > 0 %} <input type="hidden" name="properties[_gs_tags]" value="{% for tag in product.tags %}{{ tag }}{% if forloop.last %}{% else %},{% endif %}{% endfor %}"/> {% endif %}

Now that you have set up your theme to add product tags in a format Giftship can read, you will be able to use one of the following methods to adjust tax rates for your product.
Send additional information to TaxJar by configuring product tax codes.
**This step only applies to accounts who use TaxJar for tax calculation in the United States.
Using the below table of tax codes, you can add additional information about your products, so TaxJar will be able to return more accurate tax rates.
Tag each of your products have a special tax code using the below format, {{product_tax_code}} is replaced by the tax amount.
gs_product_code_{{product_tax_code}}
For example, for food and grocery type products, enter the following:
gs_product_code_40030
Repeat this step for all of your products with unique tax codes

Set up specific destination based tax rates for a product
To tag the products that require an override using the following format, where {{tax_percentage}} is replaced by the tax amount.
gs_tax_override_{{tax_percentage}}_{{2_letter_country_code}}_{{2_letter_province_code}}
For example, to charge a 10% tax on a product in which tax should be charged in North Carolina, United States, use the following format:
gs_tax_override_10.0_US_NC
Repeat this step for all of the tax rates you need to add on each product. Tax will now be calculated according to this value, assuming that tax would normally be charged at a different rate.
