How to register as an employer for PAYE

When you need a PAYE scheme, how to register with HMRC in time for your first payday, and the references that arrive when you do.
Last checked 22 August 2026

Before you start

Registration asks about the business and its first payday.
Your business details — legal structure, trading name, and address.
Your National Insurance number, or the company UTR for a limited company.
The date of the first payday, or the date you took on your first employee.
A Government Gateway account for the business.

Check whether you need a PAYE scheme

You must register as an employer if anyone you employ — including yourself as a company director — is paid £125 a week or more (the 2026/27 lower earnings limit), gets expenses or benefits, has another job, or receives a pension. If everyone is below that and has no other job or benefits, you can pay them without a scheme, but you must still keep payroll records.

Register before the first payday

Register in good time: you can't run payroll properly without your references, and it can take up to 15 working days for them to arrive. You can't register more than two months before you start paying people.
Deadline
Before your first payday — and allow up to 15 working days for your references to come through.

Note the two references HMRC sends

Registration produces an employer PAYE reference (like 123/AB456) and an Accounts Office reference (like 123PA00012345). The PAYE reference goes on submissions and payslip paperwork; the Accounts Office reference is what you quote when paying HMRC. Keep both with your payroll records.

Enrol for PAYE Online

PAYE Online is where HMRC sends notices — tax code changes, late-filing alerts, and generic notifications. Enrolment can post an activation code, so set it up before the first payday rather than after.

Run payroll and file on or before payday

Every payday you send HMRC a Full Payment Submission showing who was paid and what was deducted — on or before the day the money goes out, not at the end of the month. Payroll software builds and files it from the pay run.
Good to know
Missed or late Full Payment Submissions attract penalties once you have more than one late month in a tax year, so make filing part of the payday routine.

Don't forget workplace pension duties

Auto-enrolment starts on day one: staff aged 22 to State Pension age earning over £10,000 a year (the 2026/27 trigger) must be put into a workplace pension you contribute to. You also declare your compliance to The Pensions Regulator within five months.
Common questions

Employer PAYE, in practice

I'm a director paying myself a small salary — do I register?
If the salary is £125 a week or more in 2026/27, or you take any benefits, yes. Many one-person companies register anyway so the salary builds a State Pension year through National Insurance credits.
Does a nanny or cleaner make me an employer?
Employing someone in your home — a nanny, carer, or housekeeper — makes you an employer like any business if they earn above the limit, with the same registration and payroll duties.
What do I pay HMRC, and when?
The tax and National Insurance you deducted, plus employer National Insurance, normally by the 22nd of the following month when paying electronically. Small employers owing under £1,500 a month can arrange to pay quarterly.
What if I stop employing people?
Tell HMRC the scheme has no employees, or ask them to close it — filing nil submissions is better than going silent, because silence triggers estimated demands.
