Hi DBennett
If you're using MYOB AccountRight, this information can be displayed on payslips. Please refer to the steps given below to display balances:
Select the Print on Pay Advice option in the Entitlement Information window (Payroll > Payroll Categories > Entitlements tab > open the entitlement).

To include year-to-date amounts paid and entitlement balances (which includes any carry-over balances) on your employee pay slips, go to Setup > Preferences > Reports & Forms tab and select the option to Include all YTD amounts and Entitlement Balances on Paycheques Stubs.
This has to be done for all the entitlement accrual categories that you wish to display on the payslips. If you have further questions on this, please let us know and we'll be happy to assist.
