Employer registration should be arranged in time for the first payroll and matched to the correct employing entity. Check whether registration is required, obtain the relevant HMRC references and distinguish the employer’s PAYE scheme from an individual’s tax account.
Agree the first payday, software and person responsible for submissions. Right-to-work checks and workplace pension duties require their own preparation alongside PAYE registration.
Confirm who will employ the worker
Use the legal employer's details consistently across the employment agreement, payroll registration and payment arrangements. A founder, a limited company and another company in the same group are not interchangeable employers. If staff are moving between entities, explain that history before opening a new scheme. Registration should reflect the real arrangement rather than whichever business account is easiest to access on the day the form is completed.
HMRC says registration must be arranged before the first payday and cannot be made more than two months before payments start. Its guidance also explains what to do if pay must be processed before the reference arrives. Check the current process for the employer's circumstances and preserve the application details. A pending reference does not justify losing the records of wages actually paid. [1]
Work backwards from the first payment
Set the first payday, pay frequency and the internal deadline for receiving employee information. Allow time to obtain references, configure software and review the first calculation. The employment start date and first payday may differ, so record both. If payroll is outsourced, confirm when the provider needs instructions and who is authorised to approve them. A last-minute bank transfer should not become the substitute for a planned payroll process.
Budget for the full employment cost, including employer liabilities and pension contributions where applicable, rather than only the advertised salary. Ask the payroll adviser to explain which costs will be paid with wages and which will be settled separately. This helps the business reserve cash without confusing the net payment to the employee with the total cost of employing them for that period.
Prepare the business information
Assemble the employer's legal name, address, contact details and relevant existing tax information. Nominate a person to receive HMRC correspondence and ensure mail will reach them, particularly if a registered-office service is used. Save application confirmations in the business records. The owner should be able to establish what was submitted and by whom even when an accountant completed the registration on the business's behalf.
Keep the employer PAYE reference and accounts office reference accurately labelled once received. They serve different purposes within payroll administration, and transposing them can delay reporting or payment allocation. Avoid circulating unprotected copies of the whole registration file merely to communicate one reference. Give the payroll provider the information it needs through an agreed secure channel and retain a controlled master record internally.
Set responsibilities beyond registration
Agree who will prepare payroll, review changes, approve the final figures, submit reports and release payments. In a very small business, one person may hold several roles, but the tasks should still be explicit. Confirm how absence cover will work near payday. The process should not depend on one individual remembering both the employee payment and the separate HMRC settlement while dealing with unrelated operational problems.
Right-to-work checks, employment documents and workplace pension duties need their own preparation. Do not assume that successful PAYE registration confirms compliance with those requirements. Build a starter checklist with separate completion fields and owners. A National Insurance number can help identify a payroll record, but it should not be treated as evidence that the employer has completed the required immigration check.
Review the first completed payroll
Before the first live run, compare the setup with the agreed contract and starter information. Check spelling, start date, pay frequency, tax treatment and payment details. After processing, reconcile the approved gross pay, deductions and net amount with the bank instruction and submission receipt. Investigate discrepancies while the first run is still fresh, rather than carrying a setup error through several pay periods.
Use Information needed to put an employee on payroll for the information needed from a new employee and Payroll administration to discuss employer registration and payroll setup. State the employing entity, expected first payday and number of workers. A useful scope identifies the registration work, software setup and first payroll responsibilities separately so the business knows which tasks are included and which information it must still supply.
Keep a short implementation log covering application, references received, software configuration and first submission. This is particularly helpful if a reference arrives after payroll preparation has started, because it shows which stored reports still need attention and prevents the same wage payment being reported twice.
Illustrative scenario
A small company hires its first assistant. The owner confirms the start and pay dates, arranges employer registration and allocates payroll, pension and immigration-check tasks before the first payment.
Preparation checklist
- Confirm the employing entity
- Set the first payday
- Arrange payroll software
- Allocate related employer duties
Frequently asked questions
Does a company need to plan payroll if it only pays its director?
Yes. Check the employer registration and director payroll requirements for the actual remuneration arrangement. A one-person company should not assume that ordinary reporting duties disappear.
How early can employer registration be made?
HMRC's guidance says no more than two months before paying people. Plan within the applicable registration window and before the first payday.
What if the PAYE reference has not arrived by payday?
Follow HMRC's specific process for that situation, retaining the payroll and submission information. Do not invent a reference or omit the wage record.
Does PAYE registration complete all employer setup duties?
No. Employment documentation, right-to-work checks, pension duties and other employer obligations require separate attention alongside the payroll arrangements.
