How Can I Find My Accounts Office Reference Number?

Table of Contents

Are you not able to find your Accounts Office Reference Number? As a UK employer, this 13-character code is very important. It’s how HMRC connects your payroll taxes to your business.

HMRC requires you to pay your staff through PAYE if you are an employer in the UK. For this purpose, HMRC gives you two codes: your PAYE reference number to identify you as an employer and your Accounts Office Reference Number (AORN) to connect your tax payments to HMRC.

If you have forgotten where you have stored your Accounts Office Reference or are unsure what it looks like here, we will explain precisely what the number is, why it matters, and step-by-step ways to find it if you’ve misplaced it.

What is an Accounts Office Reference Number?

An Accounts Office Reference number is a unique code HMRC gives you when you become an employer. It’s 13 characters long and has letters and numbers.

You must use this number every time you pay HMRC so your payment is matched to your account. If you forget your Accounts Office Reference Number, it can cause delays, errors in recording and even penalty notices.

The AORN is typically used when submitting payroll information, such as the Employer Payment Summary (EPS) or the Full Payment Submission (FPS), to HMRC. It helps HMRC accurately allocate and process the payroll information for each employer.

So, when it comes to the format of the AORN, it’s a combination of a tax office number and a unique reference number that ensures proper identification and processing of payroll information.

Why is an Accounts Office Reference Number Important?

Here’s why an account office reference number is important:

  • Keeps your payments on track: If you use the correct 13-digit number, your tax payments will be processed on time and without problems.
  • Avoids fines: Using the wrong reference can cause delays and lead to penalties from HMRC.
  • Helps you talk to HMRC: It is a quick way for HMRC to look up your business when you call with a question.
  • Prevents mix-ups: It makes sure your tax records aren’t mixed up with another business, especially since it’s different from your other tax numbers.

What is an Accounts Office Reference Number Format?

The standard format is a series of numbers and letters with a total length of 13 characters. The breakdown is as follows: 

  • Characters 1–3: A three-digit number that identifies your tax office.
  • Character 4: The letter ‘P’.
  • Character 5: An alphabetic character.
  • Characters 6–12: Seven numeric characters.
  • Character 13: The last character can be a number or an ‘X’.

Example format

  • 123PA12345678
  • 123PA1234567X 

What are the Common Accounts Office Reference Number Examples?

When it comes to managing financial transactions and keeping track of accounts, reference numbers play a crucial role in identifying and organising information. There are several types of account reference numbers that you might come across in various financial contexts.

One common example is the invoice reference number, which is assigned to each invoice issued by a company. This unique identifier helps both the company and its customers easily track and reference specific invoices during payment and record-keeping processes. Another example is the bank account reference number, which is assigned to individual bank accounts.

This number helps banks and their customers identify and manage transactions related to a specific account. Additionally, in the context of tax filings, you might encounter the tax reference number, which is assigned to individuals or businesses by tax authorities.

So, when it comes to account reference numbers, they are like little tags that help keep things organised and easily identifiable in the world of finance.

How Can I Find My Accounts Office Reference Number?

To locate your AORN, you can start by checking any correspondence you’ve received from HMRC. Look for letters, emails, or documents related to your payroll or tax obligations. The AORN is often mentioned in these communications.

If you can’t find it there, you can also try logging into your HMRC online account. Once you’re logged in, navigate to the “PAYE for Employers” section.

Here, you should be able to find your AORN listed under your company’s details. Another option is to contact HMRC directly. You can reach out to their Employer Helpline and provide them with your company’s details.

They should be able to assist you in retrieving your AORN. Remember, it’s important to keep your AORN handy as it is required for various payroll and tax-related submissions. So, give these methods a go, and you’ll be on your way to finding your AORN in no time.

If you already have an AORN but can’t remember where you put it, there are several places you can check.

  • You should check your HMRC welcome letter (Form P30).
  • You can look inside your employer’s PAYE online account.
  • You can review payroll software records.
  • You may review your PAYE bills.
  • You can search HMRC correspondence.

If you cannot find it in your records, HMRC can give it to you again once they confirm your identity as the employer. You can call the HMRC Employers Helpline on 0300 200 3200. You will need:

  • Your business details
  • Your PAYE reference
  • Proof of identity

HMRC will confirm your number and send it to you.

How to Get an Accounts Office Reference Number?

Register as an Employer with HMRC:

You cannot get an AORN unless you are registered as an employer with HMRC. To register:

  • You need to go to the HMRC website.
  • Then complete the “Register as an Employer” form.
  • You need to provide your business and staff details.

Receive your PAYE and Accounts Office Reference in the welcome pack

Once you register, HMRC sends you a welcome pack. Inside, you will find both:

  • Your Employer PAYE Reference
  • Your Accounts Office Reference Number

For online registrations, the activation code is typically sent within 10 days.

You can also log into your HMRC online account to view your AORN anytime. You will find the number in the ‘Employers’ section. The Accounts Office reference is used for making PAYE payments, while the separate Employer PAYE Reference is used for payroll submissions.

AccountingFirms can assist you in managing your business and accounting problems as well as avail maximum tax relief possible.

Is A UTR The Same As An Accounts Office Reference?

You should not confuse a UTR for an Accounts Office Reference number. A UTR (Unique Taxpayer Reference) is a 10-digit number for individuals and businesses registered for Self Assessment or Corporation Tax. It is not linked to PAYE. Your UTR and Accounts Office Reference Number are entirely different codes.

Is My Accounts Office Reference Number The Same As My Payee Reference?

Your Accounts Office Reference Number is not the same as your PAYE reference. They are separate codes:

You need to know that the PAYE reference usually has a format like “123/AB456” and the Accounts Office Reference is 13 characters long, such as “123PA12345678”. Although both are important, they are used for different purposes.

Can I Change My Accounts Office Reference Number?

No. HMRC issues the number when you register, and it stays the same for the life of your business as an employer. So, you cannot change it.

The Bottom line

You can find your Accounts Office Reference Number in your HMRC welcome pack, your PAYE online account, payroll software, PAYE bills, or any HMRC letters. 

Keep this code safe, as you need it for every HMRC payment to ensure your payments are correctly recorded. Losing it could lead to missed payments, penalties, and unnecessary stress.
