# Apply tax on invoice lines

Select a tax group for each invoice line and check the saved tax amount.

Canonical: https://demo.qixcount.com/help/taxes/apply-tax-on-invoices

Who can do this: Owners; *View invoices* to open; *Create invoices* for a new invoice or *Edit invoices* for a draft

Where: Sales, then Invoices

You'll need: An active tax group for the selected invoice lines; a draft to change existing amounts

## Choose tax for a line

Open **Sales**, then **Invoices**. Select **New Invoice**, or open a draft and select **Edit**. Enter the customer and line items. Opening the list and draft needs *View invoices*.

1. In the line's **Tax** column, select the tax group. Scroll the line table horizontally if the column is outside the visible area.
2. Repeat the selection for each line that needs a group, using **No Tax** for lines with no selected rate.
3. Select **Preview Invoice** to check the calculated document if you have *Create invoices*.
4. Select **Save as Draft** on a new invoice, or **Save Changes** on the edit form.

## What happens next

Saving calculates tax from each line's amount after its line discount, using the selected group's currently active rates. A customer whose saved exemption passes QixCount's expiry check has no invoice tax calculated. See [exemption certificates](https://demo.qixcount.com/help/taxes/exemption-certificates).

New lines begin with No Tax, so check their selections even if a default tax group exists. The saved calculation can differ from the form's running estimate, particularly with compound rates. Saving a draft does not send it to the customer.

## Good to know

Invoice tax is selected per line.

Different lines can use different groups, or no tax. You need *Create invoices* for a new invoice and *Edit invoices* to change a draft. Only drafts allow line changes. The preview action also needs *Create invoices*, including when used from the edit form.
