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.

Make sure you did not create a VAT 100% transaction and then left the option "inclusive of tax".
this will make the VAT 50% of the total amount since you informed the system the VAT is part of the total amount that you entered by selecting "inclusive of VAT".
Nonetheless, Custom VAT codes will not be accepted into the VAT submission.
To raise a VAT 100% transaction:
1st-Click on the (+) icon and select the transaction type that you need. Bill/expense for money out or a sales receipt/invoice for money in.
2nd-On the first line transaction, choose the Item/category you want to use. For the rate, enter £0.01, and for the VAT code, select the 20% Standard code.
3rd-On the second line, select the same item/rate. For the rate, enter -£0.01, and choose an Exempt code.
4th-The total of the invoice will be 0. On the bottom, you will be able to enter the value of the VAT you Paid or will claim on the VAT 20% total.
5th-Enter the correct date and Bank account that you want to use on this transaction.
6th-Save.
