How do I add a VAT line on my invoice when I create one?

Hello there, legal1.

If we have created a new vat, it'll automatically show on the invoice as long as it is not set to inactive. We can go to the VAT lists to review and ensure that it wasn't deactivated. I'll guide you on where to check it out. Here's how:

1. Go to VAT on the left panel.
2. Click the Edit drop-down arrow at the upper-right corner.
3. Select Edit rates.
4. Hit the small Gear icon and put a check mark inside the Include inactive box. It's a way to view all VATs, including the inactive ones.
5. Find the tax name or description. Then, switch it on to activate it. 

This way, it'll show as one of the options in the VAT column on the invoice. On the other hand, if we haven't created another VAT, we can follow these steps on how to set them up:

1. Within the VAT rates page, click the Add tax rate at the upper-right corner.
2. Enter the needed information such as, tax name, description and tax agency.
3. Then, Save.
