Hello and welcome to the Community, sarah-hoy1
Sorry for the delay in responding to your post. At the moment, adding a pre-tax leave deduction in Core Payroll is not available and would need to be treated by our team as an area of enhancement.
If you need the feature urgently, you may consider upgrading your subscription to QuickBooks Online Payroll Advanced. If you'd like to talk to us about switching, our live messaging support is available 8.00am - 10.00pm Monday to Friday, 8.00am - 6.00pm Saturday & Sunday.
Thanks for reaching Intuit QuickBooks support. We're just a post away if you have further questions or require additional assistance.
