Glad to have you back here in the Community, @Alexis8.
I'd like to ensure that you can create and apply a 100% custom vat rate successfully to your transactions in QuickBooks Online.
To get this issue sorted out, I recommend performing the steps shared by Anonymous, which is to access your account in a private window. Then clear its cache to see if it works fine.
If the problem continues, I suggest inactivating and recreating the VAT rate that you made.
To eliminate the rate:
- Go to Taxes in the left menu.
- Select on Edit VAT.
- Choose on Edit Rates.
- Find the tax rate you want to deactivate, then switch it from On to Off.
- Hit on Yes.
After that, create the vat code again by following the steps found in this link: How to create an additional VAT code unique to your company.
If doing this doesn't make a difference, I recommend contacting our Customer Care Team. They have the necessary tools that can help determine the reason behind this issue and will give you a fix.
Lastly, I'd like to share this link reference to contains details about everything that you need to know concerning VAT in QuickBooks Online: VAT for QuickBooks Online UK.
