Is there a report which is the equivalent of the old payroll P35 tax year end report?ie one that lists the totals for all employees?

Hi there, Du4Accounts.

P35 Return is the annual summary of all amounts. With this, you can pull up the Annual Payroll Summary report as it lists all employee and employer totals for the year: 

1. Sign in to QuickBooks Online.
2. Select Reports.
3. Select All reports.
4. Select Payroll Reports.
5. Select Annual Payroll Summary.

Other payroll reports available can be found in this article: View reports in QuickBooks Online Standard Payroll.
