Hello tigarc-worldonli!
I know how important VAT is. I'm here to help you with any questions you may have but I'd like to know more about it.
Can you please share more details about it? What do you mean by not working?
I added a link if you need help in setting up your VAT: Set up and use VAT in QuickBooks Online.
Leave a reply below and I'll respond as soon as I can.
