My boss deducts my tax before paying me. How do I show what tax I've paid?

Hi there, Steve. QuickBooks Sole Trader will only show what’s recorded in the system. If the payment coming into your bank account is already net of tax and no payroll details have been entered, it won’t automatically display your gross pay. In this case, the most accurate source for your full breakdown is still your payslip or payment summary from your employer.
 

You can use that payroll statement to see your gross amount, tax deducted, and net pay, and refer to it when reviewing your records in QuickBooks. It’s a good idea to reach out to your boss or employer to request the full details if you don’t already have them.
 

If you have any other questions, just reply here and I'll be happy to help.
