Taking on employees or paying yourself a salary as a company director means you’ll probably need to register for PAYE UK. It is a system used by HM Revenue and Customs (HMRC) to collect income tax and national insurance contributions from employees. This might sound a bit intimidating, but it’s a necessary step.

This guide provides what’s needed to register for PAYE UK and deal with running payroll software. Think of it as your one-stop-shop for everything related to employer PAYE registration.

Do you need to register for PAYE?

If you’re employing staff and paying them above a certain amount, PAYE registration is unavoidable. This is the case even if it’s just *you* as the sole director of your limited company.

Generally, you need to register as an employer with HMRC if you’re going to pay employees a certain rate. The salary for your employee(s) must be £120 or more per week.

When to register

You need to register before your first payday. This can take a while to complete, although five days or less is common. This process might seem lengthy, so it is best to begin sooner rather than later.

You can’t register more than two months before you begin to pay people. So, don’t sign up too early, but give yourself sufficient time to do so. Get all your documents in order, but you can’t get ahead of the game by registering far in advance.

What happens if you need to pay staff immediately?

Sometimes things happen. Say a star candidate shows up ready to contribute immediately, it is possible to sort it all out after they have begun.

You should record these instances where this takes place. Once you do get your employer PAYE reference number, you can submit a late Full Payment Submission to HMRC.

You can submit this late Full Payment Submission to explain and account for what has happened.

How to register for PAYE UK

The actual PAYE registration is not something that you should lose any sleep over. Most limited companies are able to do so online and quite quickly.

So don’t worry if you’re anxious or new to these types of things. The steps involved make the whole thing much simpler.

Here’s how to do it, step-by-step:

  1. Go to the Government Gateway. If you haven’t got any Gateway credentials, you are going to have to get some now.
  2. Add taxes. Choose ‘Register for PAYE’ here.
  3. Fill in the HMRC details asked for on the screen, giving a National Insurance Number where applicable.

Once completed, you are done. At some point, your details will come through by mail.

What happens next

HMRC should provide you with two details by mail.

  • Employer Reference Number (ERN).
  • Accounts Office Reference Number (AORN).

These are what are required to submit forms online, with HMRC approved software used. HMRC has stated that it may take up to 20 business days to supply a PAYE number.

Adding PAYE to your gateway account

In addition to signing up for PAYE you also have to add a PAYE scheme to the Gateway to make sure you’re totally legitimate.

  1. Click ‘Add Taxes’. You want to click on ‘PAYE for Employers’.
  2. You can then insert these references you were sent, this begins the formal connection of things together. This will lead to HMRC sending out an activation number by mail.
  3. When you have got the code, put this on the online account as well, which makes your account fully set up.

This all might appear involved on the face of things. But following step-by-step guides can alleviate some of that initial apprehension.

PAYE for different business types

Are you self employed, or maybe you are a sole trader. What does all this have to do with you, specifically? Things do vary based on what category you fall under.

Sole traders and self-employed

As a sole trader, you probably will not ever be paid a salary. So PAYE should not normally be something that you will concern yourself with too often.

This situation may change in the future. It may very well change as a company develops and scales over time.

Limited companies

A Limited Company is treated slightly differently, as legally speaking the company is different from you as an individual. Register even if you’re using subcontractors.

Register even if it’s solely you who draws a wage. Many limited companies can go down the online route.

After you’ve done it, you will have a bit of a wait. But keep an eye out, as post can arrive a little earlier sometimes.

Keeping records and staying compliant

Once registered, what happens next? Record keeping and following guidelines will come into play to stay on the straight and narrow path.

Remember, details such as names and addresses have to be kept safely and your data protection obligations must be met. Your PAYE scheme information has a maximum storage duration of three years after the end of the tax year they relate to.

Running payroll

When it comes to running payroll, you’ve basically got two options:

  • Take care of it on your own, dealing with records and reporting.
  • Give it over to another body.

Either route will get you there, just make sure the payroll you’re implementing runs without too many problems. If paying an employee, you must provide them with a payslip for each pay period, detailing earnings before and after any deductions.

Below are some important terms and details relating to running payroll.

Term

Description

Gross Pay

The employee’s pay before any deductions.

Net Pay

The employee’s pay after deductions.

Deductions

These can include income tax, National Insurance contributions, workplace pension contributions, and student loan repayments.

Tax Code

Determines an individual’s tax allowance.

Annual responsibilities

At the conclusion of a tax year, specific details do need to be sent out. Some annual details need to be supplied.

  • Give out P60 details by the final day of May.
  • Submit a P11D form at the conclusion of a tax year by early July if relevant to your organisation.

You will probably not have all the time and resources necessary to take care of it, yourself, always. Look into assistance.

A P60 form, or ‘End of Year Certificate’, summarises an employee’s total pay and deductions for the tax year. The P11D form is used to report any expenses or benefits provided to employees that haven’t been taxed through payroll.

Conclusion

For many UK-based businesses, handling payroll and figuring out how to register for PAYE UK can feel really involved. Getting help is one solution that takes care of all these kinds of administrative requirements.

Knowing exactly what’s expected helps put many minds at ease. The system for employers to register for PAYE UK is well established.

Take a pragmatic view and make the decision whether you go it alone or let an alternative system take the burden.

FAQs on how to register for PAYE in the UK

PAYE (Pay As You Earn) is the UK’s system for collecting Income Tax and National Insurance contributions (NICs) from employees’ wages. You must register for PAYE if:

  • You pay any employee (including directors) £123 or more per week.
  • You provide taxable benefits (e.g., company cars, bonuses, pensions).
  • You have employees with another job or receiving a pension.

If your employees earn below £123 per week, PAYE registration is not required, but you must still keep payroll records.

To register for PAYE, follow these steps:

  1. Set up your limited company or business with HMRC.
  2. Register for PAYE online via the HMRC website (takes up to 5 working days).
  3. Receive your PAYE reference number from HMRC.
  4. Choose payroll software to run payroll and submit reports to HMRC.
  5. Start processing employee wages and deductions.

You must register before the first payday, but no more than two months in advance.

After registering for PAYE, HMRC usually issues your PAYE reference number within 5-10 working days.

This number is sent via post and is needed to:

  • Submit payroll reports (RTI – Real Time Information).
  • Pay tax and National Insurance for employees.
  • Manage PAYE online services.

If you don’t receive your reference within two weeks, contact HMRC’s Employer Helpline.

If you fail to register for PAYE, you may face:
Penalties from HMRC for non-compliance.
Incorrect tax and NI payments, leading to backdated tax bills.
Legal issues if employees do not receive payslips and deductions properly.

To avoid fines, register for PAYE before the first payday and use HMRC-compliant payroll software.

Yes, you can run payroll yourself if you:
– Use HMRC-recognized payroll software.
– Submit Real Time Information (RTI) reports to HMRC on time.
Deduct and pay tax & NI correctly for employees.

However, many businesses hire an accountant or payroll provider to manage PAYE, ensuring compliance with tax laws and avoiding errors.
