I have a permanent employee and for some reason quickbooks hasn't accrued his annual leave. It is showing as balance 0 and he should be entitled to at least 31 hours can

Hi mandy_13_1984-ho,

Thanks for posting in the Community! Let's check the employee annual leave category setup. 

1. Go to Employees tab.
2. Select an employee.
3. Select Leave Allowances.
4. See if employee can apply for leave and if it accrues on Annual Leave category. 

Next thing to check is if Automatically accrues option is enabled on your Annual leave category. 

1. Go to Employees tab and select Payroll Settings.
2. Select Leave Categories. 
3. On Annual leave, tick Automatically accrues.
4. Then click Save. 

If there's a need to adjust the employee's annual leave balance , you can do it on a pay run. 

Here's how:

1. Open or create a pay run.
2. Select an employee to expand details on it.
3. Select Actions and then select Adjust Leave.

Then specify the type of leave to be adjusted, and the number of units to adjust by. If you enter in a positive number, the leave balance will increase, whereas if you enter in a negative figure, the balance will decrease.
