When Do You Get a UTR Number? (Timeline)
How Long Does It Take to Get Your Unique Taxpayer Reference?
You’ve registered for Self Assessment, completed the forms, and now you’re waiting. The question on your mind is: when will I actually receive my Unique Taxpayer Reference (UTR) number?
The answer depends on how you registered. This guide provides a clear timeline for both online and postal applications, explains what to expect, and offers practical advice on what you can do while you wait for your UTR to arrive.
The Short Answer: Online vs. Postal
The time it takes to get your UTR varies significantly based on your registration method.
| Registration Method | Typical Time to Receive UTR |
|---|---|
| Online Registration | Around 10 working days (HMRC sends it by post) |
| Postal Registration (Paper Form) | Up to 6 weeks |
Important: HMRC will only send your UTR by post to the registered address they have on file. They will not email it or give it to you over the phone for security reasons.
Method 1: Registering Online (The Faster Route)
If you registered for Self Assessment online via the HMRC website or the HMRC app, the process is generally quicker.
The Step-by-Step Process
What to watch for: Ensure your address is correct during registration. If you have moved or provided a wrong address, your UTR will be sent to the wrong place.
Method 2: Registering by Post (The Slower Route)
If you registered using a paper form (like the SA1 form for individuals or the SA401 for partnerships), the timeline is considerably longer.
The Paper Form Process
Total Timeline: This entire process can take up to 6 weeks from the date you posted your form.
Why Does It Take This Long?
The delay is primarily for security and administrative reasons:
- Security: HMRC will not share your UTR over the phone or via email to prevent fraud.
- Address Verification: Posting the letter to your registered address ensures that the UTR reaches the correct person.
- Processing Volumes: HMRC handles a massive volume of registrations, especially around the tax year-end and the January filing deadline, which can cause delays.
What to Do While You’re Waiting for Your UTR
Waiting for your UTR doesn’t mean you have to delay all your tax planning. Here are some productive steps you can take.
Get Your Financial Records in Order
Use this time to gather and organize the documents you will need for your Self Assessment. This is one of the most time-consuming parts of filing, and doing it in advance will save you significant stress later.
- Collect P60s and P45s from your employment
- Gather records of self-employed income, including invoices and bank statements
- Assemble receipts and records for your expenses
- Organize records of rental income and property expenses
- Compile statements for investment income and Capital Gains

What If Your UTR Doesn’t Arrive on Time?
If the expected timeline has passed and your UTR hasn’t arrived:
- Check your address: Ensure HMRC has your current address. If you have moved, you may need to update your details.
- Contact HMRC: You can call the Self Assessment helpline (0300 200 3310) to check the status. However, as covered in our other guides, they will not give you the UTR over the phone and will likely have to re-send it.
- Use Our Agent Service: As a registered HMRC Agent, we can contact HMRC through our dedicated support line to check on your registration and retrieve your UTR, often much faster than you can on your own.
