Change tax code to charge in reverse or edit withholding tax name to ARSP

Greetings to you , I’m inquiring if its possible to have the tax code affect my invoice value by reducing in the totals by the percentage computed , in my case i invoice the subtotals and then the would be withholding tax here is called ARSP, i would like the ARSP to act like withholding tax with all the effecting part to my invoices , i set the percentage 1.20% and if the total is 400$ after applying tax the payable would be 395.2 that’s the receivable as per the invoice , the payer withhold the 4.8 and pay it to the government , what i receive is the exclusive of taxes ,but the title shouldn’t be withholding tax but ARSP on the invoice
secondly ,how do you retrieve the reset withholding tab from the manager io, i reset mine in thinking i can reedit to ARSP.
Your help is highly awaited , thanks
