# Marking a Product as Taxable

> Flag a product as taxable so fusionCore charges tax on it automatically during Order Entry.

## Marking a Product as Taxable

You mark a product as taxable by checking a single checkbox on the product record. Once a product is taxable, the tax engine calculates and applies tax automatically when the product is added to an order during Order Entry (and on the draft Opportunity).

<Steps>
  <Step title="Open a non-tax product record">
    Open a **non-tax** Product (`Product2`) record.
  </Step>

  <Step title="Check the Is Taxable checkbox">
    Check the **Is Taxable** (`Is_Taxable__c`) checkbox.

    </Frame>
  </Step>

  <Step title="Save the product">
    Click **Save**.
  </Step>
</Steps>

<Note>
  Marking a product as taxable only tells the engine that tax should apply. The amount of tax charged is determined by the tax product the engine selects for that order. See [Tax Products](/end-user-guides/products/taxes/tax-products).
</Note>

## Limitations and Common Pitfalls

* **Exempt customers still get a tax line.** For a tax-exempt customer, fusionCore does not suppress the tax line — it writes the line with a \$0 amount.
