There are invoices have 2 different type of tax and there is one type of tax which is 14% VAT so i want to add tax code with 0%

You've come to the right place, @userahmedsobhi474.

I can guide you in creating a tax code so you can apply it to invoices. Here's how:

1. Go to the Tax menu.
2. Choose Add Tax.
3. Select Tax Rate.
4. Enter the details of your tax rate. 
5. Click Done.

Now, you can create an invoice and add a VAT code to it. You can read through this article for more detailed instructions in setting up VAT in your account: How do I set up sales GST/VAT rates and use them on forms? (International QBO).

Also, I've added these articles to help you manage VAT in QuickBooks:
