# Remove Tax from an Invoice if the Tax Area is Grayed Out

## Problem

You are unable to edit the tax field to remove tax from an invoice.

## Solution

1. [Search for](/v1/docs/use-search-in-servicetitan) and go to the invoice.
2. On the invoice record, click **Update invoice details**.
3. Edit the tax field to 0.00.
4. Click **Save**.

If the Tax field is grayed out and you are unable to edit it:

1. Post the original invoice.
2. [Create an adjustment invoice](/v1/docs/create-an-adjustment-invoice).
3. On the adjustment invoice, add a service.
4. Select a service item from your pricebook (such as a miscellaneous or adjustment service item), set the quantity to **-1**, and set the price to the tax amount you want to remove.

> [!NOTE]
> **Note:** If you do not have a service item for this purpose, create one in your pricebook before you continue.
5. Save the adjustment invoice.
6. The tax will now be removed from the original invoice balance.
