The first step is to ensure there is a deduction set up called IRD Arrears.
It is best to leave the Calculation Method as Fixed Unit Value $1.000 so it can be used in future situations.
If unsure about setting up a new deduction see Allowance & Deduction Setup
The next step is linking the employee to the IRD Arrears deduction.
Enter in the Usual Units field the amount the IRD has asked you to deduct each pay.
If unsure of the process see Allowances & Deductions - Employee Linking
If the IRD has specified a total amount that must be paid, set it up as a reducing balance deduction.
If unsure of the process see Reducing Balance Deductions.
After having entered the total amount that must be paid, Ace Payroll deducts the amount each pay period, and automatically stops when the balance is repaid.
The deduction can be linked to a bank account so it is paid to the IRD automatically.
If unsure of the process see Linking Deductions to Direct Credits.
When linking the deduction ensure the reference details given to you by the IRD are entered.
This ensures the deduction is correctly allocated at the IRD end, and is the reason IRD arrears are paid seperately from PAYE deductions.
