I am embarrassed to say this - but I'm still using HMRC's Basic PAYE Tools. It suits me - as all schemes are for directors - no other employees and no Automated Pension etc.
And it all worked fine but I rang a HMRC Helpline for a query on another payroll matter and they said that there was a limit to the number of schemes that could use the software. I know its 9 staff per scheme but I wasnt aware of any other limit. HMRC person said '15 or 16' but wasnt sure.
Does anyone know?
