Hi Adrian17,

For each of the pay runs related to the annual leave, you can adjust the Date Paid to 20/12/19, even if the pay runs are related to future dates. 

If you have finalised the 3 pay runs, unlock them first. Then, select one of the pay runs and select Pay Run Actions, then Adjust Pay Period. Change the Date pay run will be paid to 20/12/19 and Save. The pay slips will then be updated to reflect that date paid. Repeat for the next 2 pay runs.

When you change the Date Paid, it will also adjust the PAYG and Super amounts automatically, according to that date paid's period. If you are paying PAYG monthly or quarterly, then the annual leave payout's PAYG will be calculated as part of the December BAS/IAS.

Bonny
