What is a tax code?
Tax codes determine whether a line is taxable. This one is non-taxable:

Our software maps the tax code for items, discounts, and shipping methods using different actions:
- Map order item tax code for products
- Map shipping tax code for shipping
- Map discount tax code for discounts
We will cover how to map in this guide.
How do I create a rule to map order item tax codes?
In this example, we map a tax code for taxable items to AVA. Here are the steps:
- Login to Connex.
- On the left, click Rules Engine > My Rules.
- Click Add New Rule
- For 'Type of Rule', choose 'Map field, based on a condition'. Click Advance.
- Give your rule a name, and for step 2, choose 'Map Tax Code on Order Items':
- For step 3, 'What conditions need to be met for this rule to execute?', click Add and enter your conditions. Choose Total Tax as the Field to Check, More Than as the Comparison, and Zero (0) as the value. Then, click Update.
- For step 4, 'What should the value be?', enter AVA and click submit.
How do I map the tax codes on the shipping line item?
In this example, we will add a rule called SHP. The rule will run, if the order has tax and if the shipping state is RI. If the shipping method is not empty, then apply the code SHP.
- Login to Connex.
- On the left, click rules engine > my rules.
- Click add new rule.
- For 'Type of Rule', choose 'Map field, based on a condition'. Click Advance.
- Give your rule a name, and for step 2, choose 'Map Shipping Line Tax Code':
- For step 3, 'What conditions need to be met for this rule to execute?', enter shipping state and total tax as the conditions. Use an AND statement:
- For step 4, 'What should the value be?', enter SHP. Then, 'Submit' your rule.
How do I map tax codes on discounts?
In this example, we will map OUT for discounts when there is no tax:
- Login to Connex.
- On the left, click Rules Engine > My Rules.
- Click Add New Rule.
- For 'Type of Rule', choose 'Map field, based on a condition'. Click Advance.
- Give your rule a name, and for step 2, choose 'Map Tax Code on Discount'.
- For step 3, 'What conditions need to be met for this rule to execute?', click Add and enter your conditions. Choose Total Tax as the Field to Check, More Than as the Comparison, and Zero (0) as the value. Then, click Update.
- For step 4, 'What should the value be?', enter OUT.
