Hi SL88, 

Thanks for joining us here on the Community, 

Please first check that when clicking 'continue setup' there are no incomplete fields marked with an asterisk or highlighted in red.

If you'd already had a draft pay run saved before editing the tax code, please delete this as the system will not take the change into account, and then attempt to re-run. 

If you're still having trouble after checking this, please get back to us below, and advise whether you're running the Advanced or Standard payroll.

Thanks again :)
