Hey Supporter,
Actually, the case was that earlier in PayPlans there 2 taxes only, personal tax and Business tax which is applicable when the user will fill vat number as well as the company.
For that user, he wants to offer 2 types of business tax B2B and B2C, B2C is not the same as personal tax in that case.
So there are 2 business taxes introduced, business tax when the user fills only the company name, o vat id is required and another one which requires vat id with the company name, in that case, different taxes need to apply.
As mentioned here:

Even Hikashop also allows this configuration, We need to introduce this new business tax to solve the problem where vat id is not required and the company name is there, so in that case, a different business tax needs to apply which is not the same as personal tax.
If in your case B2C and personal tax both are the same then don't need to set the business tax without vat id, in that case, the personal tax will be applied when vat id is not there.
Hope this is clear.
