PAYE Registration Assistance Services

PAYE registration is a legal requirement for any UK business that pays employees, directors, or benefits in kind. Form My Company prepares and submits your PAYE registration directly to HMRC. 

What Is PAYE Registration?

PAYE (Pay As You Earn) is the HMRC system for collecting Income Tax and National Insurance Contributions (NICs) from employee wages before they are paid. Every UK employer must register before making the first payroll payment.

PAYE is the mandatory payroll tax framework administered by HM Revenue and Customs (HMRC). When a Limited Company, Limited Liability Partnership, or sole trader takes on staff, including a director drawing a salary, the business becomes a legal employer. That employer status carries a statutory obligation: register for PAYE before the first payroll date.

Once registered, HMRC issues a PAYE reference number (also called an Employer Reference Number, or ERN). This 3-digit HMRC office number and 10-character reference code are required for:

• Filing Real Time Information (RTI) payroll submissions each pay period
• Issuing P45 and P60 forms to employees
• Paying Income Tax and National Insurance Contributions to HMRC
• Operating a Construction Industry Scheme (CIS) if applicable

Failure to register on time results in HMRC penalties starting at £100 per PAYE scheme per month, plus interest on unpaid liabilities.

Who Needs to Register for PAYE?

A business must register for PAYE if it employs at least 1 person and pays wages above the Lower Earnings Limit (LEL), currently £123 per week (2024/25 tax year). This applies to Limited Companies, LLPs, and sole traders.

You are legally required to register for PAYE if any of the following apply:

• You employ a member of staff on a salary, hourly wage, or retainer
• A director of a Private Limited Company (Ltd) takes a salary from the company
• Employees receive benefits in kind, for example, a company car, private medical insurance, or employer pension contributions above the basic rate
• You pay employees’ expenses that are not covered by an HMRC dispensation
• You operate a director-only payroll (often set up at the National Insurance Secondary Threshold to minimise Class 1 NICs)

Sole directors paying themselves via dividends only do not require PAYE registration, provided no PAYE income is processed. However, most directors combine a small salary with dividends. This combination requires a PAYE scheme in place before the first salary payment.

If you have recently completed company formation and are now preparing to take on staff or start a director payroll, registering with HMRC is the next mandatory compliance step.

What Does PAYE Registration Include?

Form My Company’s PAYE Registration Assistance covers preparation of your HMRC employer registration application, electronic submission to HMRC, and delivery of your PAYE Employer Reference Number (ERN). 

Service Specifications:

What is not included: Ongoing payroll processing, RTI filing, P60 or P11D preparation. These are separate payroll compliance services. If you need ongoing payroll management, speak with a qualified UK accountant.

What Information Is Required to Register for PAYE?

To complete your PAYE registration, HMRC requires your company registration number, registered office address, date of first payday, and the details of at least 1 director or payroll employee.

You will need to provide the following information when using our service:

1. Company name — exactly as registered at Companies House
2. Company Registration Number (CRN) — your 8-digit Companies House identifier
3. Registered office address — your official UK address on the Companies House register
4. Date employees will first be paid — PAYE registration must be completed before this date
5. Number of employees you intend to pay in the first pay period
6. Director details — full legal name, National Insurance number, and date of birth if a director is being included in the payroll
7. Business activity — a brief description of your company’s trading purpose

All information provided is processed securely. If you need a registered office address for your business, this can be arranged separately before completing your PAYE application.

How Does the PAYE Registration Process Work?

The process has 4 steps: you submit your details online, we review and prepare your application, we file electronically with HMRC, and HMRC issues your PAYE Employer Reference Number by post within 5–20 working days.

Step 1 — Purchase and Submit Details Complete our secure online form with your company registration details, director information, and intended first payroll date. 

Step 2 — Application Review Our compliance team reviews your submission for accuracy. Errors in PAYE applications cause HMRC delays of up to 6 additional weeks. We verify all details before submission.

Step 3 — Electronic Submission to HMRC We submit your PAYE employer registration to HMRC electronically via the official HMRC online service portal. Applications submitted electronically are processed faster than postal applications.

Step 4 — Receive Your ERN HMRC posts your PAYE Employer Reference Number to your registered office address. Standard processing: 5–10 working days. Peak periods (March–June, coinciding with UK tax year end): up to 20 working days. You will also receive an HMRC activation code for PAYE Online, the employer payroll submission portal.

Once your ERN arrives, you activate your PAYE Online account and can begin processing payroll, submitting RTI Full Payment Submissions (FPS), and paying HMRC each month or quarter.

How Long Does PAYE Registration Take?

HMRC processes PAYE employer registrations in 5–10 working days for electronic applications. Postal applications take 20 working days. Peak periods around the UK tax year-end (April) extend these times.

Important: PAYE registration must be completed before the first payroll date. If you are forming a new company and plan to employ staff from day one, begin the PAYE registration process immediately after company incorporation. HMRC does not backdate PAYE registration, and operating payroll without a scheme in place is a statutory breach.

If your first payday is within 5 working days, contact our support team immediately to discuss options.

What Happens After PAYE Registration?

After HMRC issues your Employer Reference Number, you must activate your PAYE Online account, enrol for RTI reporting, and submit a Full Payment Submission (FPS) on or before each payday.

Your ongoing PAYE compliance obligations after registration:

• RTI Full Payment Submission (FPS): Filed each payday via payroll software or HMRC’s Basic PAYE Tools (free for fewer than 10 employees)
• Employer Payment Summary (EPS): Filed monthly if you have no employees to pay in a given period, or to claim statutory pay rebates
• Monthly PAYE payment to HMRC: Due by the 19th of each month (22nd for electronic payment) covering Income Tax and NICs deducted from employees
• P60 forms: Issued to each employee by 31 May each year, confirming annual earnings and deductions
• P11D forms: Filed annually by 6 July if employees receive taxable benefits in kind

If your annual PAYE liability is less than £1,500 per month, HMRC permits quarterly payments instead of monthly.

For businesses managing multiple compliance filings throughout the year, our Company Secretarial Service provides ongoing compliance support across all statutory obligations.

Can a Director Register for PAYE Without Other Employees?

Yes. A director-only PAYE scheme is a standard and legitimate payroll structure. A Limited Company director who takes a salary, even a minimal one, requires a PAYE scheme registered with HMRC before the first payroll payment.

Most company directors structure their remuneration as a combination of:

• A salary at or near the National Insurance Secondary Threshold (£9,100 for 2024/25) — this amount is deductible as a company expense and keeps the director within the basic rate Income Tax threshold
• Dividends from company profits, which are drawn separately and taxed at dividend tax rates

The salary element requires a PAYE scheme. The dividend element does not. This is a legal and tax-efficient structure used by the majority of UK Ltd company directors.

If you are setting up a Private Limited Company and intend to pay yourself a director’s salary, PAYE registration is required before your first payroll run.

Do I Need VAT Registration as Well as PAYE?

PAYE and VAT are separate registrations. PAYE covers employer payroll tax obligations.  The two registrations are independent.

Many new businesses need both registrations at different stages:

• PAYE registration — required before the first payday, regardless of turnover
• VAT registration — required once taxable turnover crosses £90,000 in a rolling 12-month period, or voluntarily at any point

Our VAT Registration Assistance handles the VAT application process with HMRC in the same way we prepare, review, and submit your application on your behalf.

What Is the Difference Between PAYE and CIS?

PAYE is the Income Tax and National Insurance deduction system for employees. CIS (Construction Industry Scheme) applies to subcontractor payments in the construction sector. Some construction businesses need both schemes registered with HMRC.

If your Limited Company operates in the construction industry and both employs staff and engages subcontractors, you need:

1. A PAYE scheme for employees
2. CIS registration as a contractor (and potentially as a subcontractor)

These are 2 separate HMRC registrations with different reporting requirements. Our PAYE Registration Assistance covers the employer PAYE scheme. CIS registration is a separate process.
