Thanks for joining in the thread, @Shivani. I'd like to provide some insights about the NI Number.

The NI number refers to the National Insurance Number. You can obtain this number by asking your employees. They can check payslips or P60's from a previous employer as these may contain their NI Number. They can also check any letters received regarding taxes, pensions, or benefits for Government departments.

For future reference, you can also read this module about handling payslips in QuickBooks: View, email, and print payslips after running payroll.

Fill me in for more questions about payroll or QuickBooks. Have a great weekend ahead!
