Tax Basis Formula to divide VAT Line Amount

Content (please ensure you mask any confidential information):

Hi,

I would like to create a tax formula to solve these cases:
400 invoice line amount with two different accounting distributions with VAT Code 23% and we need to deduct 50% of the VAT (the other 50% should increase the net amount).

So the VAT amount that should increase the net amount is (400x23%) = 92 x 50% = 46.
I would like the net amount 446 to be split 75% on the first line of the accounting breakdown and 25% on the second line when accounting.
So, in this case, when I account for the invoice I need to display the amount 334.50 on the first distribution line and 111.50 on the second distribution line.
