Hello, I have the same question.

I am using Quickbooks Standard Payroll.

How do I know how much monthly PAYE and NI to pay HMRC... Right now we have a large credit on our HMRC account having back-claimed 4 years of Employment Allowance, so we are not paying HMRC anything right now but once this credit has been used up, how will I know how much to pay each month?

I am new to QB - my old payroll system used to generate a PAYE remittance report each month, which showed tax and NI owed and the EA deduction for the month but I don't see that here on QB.

Thanks.
