If your business employs people, then you must register for a payroll scheme.
This will enable your business to keep a formal record of the income tax and national insurance collected by the business, and to be reported to HM Revenue & Customs.
With increasing automation, HM Revenue & Customs are demanding reports be filed more frequently (RTI is such an example here), and payroll is no exception. The introduction of auto-enrolment pensions is another example of increasing reporting, being linked to payroll.
We can manage this aspect of your business on your behalf.
If in doubt, talk to us.
