If you’re searching for how to request a copy of a Corporation Tax UTR, you’re in the right place. Every year, thousands of company directors misplace their UTR number or need a replacement urgently. Whether you’re filing a tax return, appointing a new accountant, or responding to HMRC, having your Corporation Tax Unique Taxpayer Reference (UTR) is essential.
The good news? Getting a replacement is straightforward when you follow the correct process.
In this guide, we’ll walk you through exactly how to request a copy of your Corporation Tax UTR, what information you’ll need, who qualifies, and how long it takes to receive it.
Before requesting a replacement, it helps to understand what this number represents.
A Corporation Tax UTR is a unique 10-digit number issued by HMRC when your limited company registers for Corporation Tax. It acts as your company’s official tax identifier.
Think of it like a tax ID card for your business. HMRC uses it to track:
Corporation Tax returns (CT600)
Tax payments
Official correspondence
Penalties or refunds
Every limited company registered in the UK receives one.
Once your company is incorporated with Companies House, HMRC automatically registers it for Corporation Tax. Shortly after incorporation, HMRC sends your UTR by post to your company’s registered office address.
It is never emailed. This is done to protect sensitive information.
You’ll need your UTR when:
Filing your annual Corporation Tax Return
Appointing an accountant
Registering for HMRC online services
Speaking to HMRC about your company
Without it, progress can stall quickly.
There are several common reasons directors search for a copy of a Corporation Tax UTR.
It’s surprisingly common. The original letter may have been:
Sent to an old address
Misfiled
Thrown away accidentally
If you can’t locate it, requesting a replacement is the safest option.
Your accountant will request your UTR before acting on your behalf. Without it, they cannot file returns or access HMRC systems.
If your filing deadline is approaching and you can’t find your UTR, time is critical. Requesting a replacement early avoids late filing penalties.
Sometimes directors simply want to ensure their company records are complete and up to date.
Not every company qualifies for the service.
You can request a copy if your company is:
Active
Registered with Companies House
Not dissolved or struck off
The service verifies your company details automatically.
You cannot request a copy if your company has been:
Officially dissolved
Struck off the Companies House register
Converted into a different type of organisation
Very recently incorporated (your original UTR should arrive shortly)
Preparation saves time. Before starting your request, make sure you have the following details exactly as they appear on Companies House.
Your CRN is either:
8 digits
OR
2 letters followed by 6 digits

Accuracy matters. Even a small error can delay the process.
Enter your company name exactly as listed, including:
LIMITED or LTD
Spacing
Punctuation
It must match the Companies House register precisely.
Your replacement UTR will be posted to the registered office address on record. HMRC does this for security reasons.
If your address is outdated, update it with Companies House first.
Here’s the exact process.
Go to the official HMRC service page for requesting a copy of your Corporation Tax UTR.
Always use GOV.UK — never use third-party websites for sensitive tax information.
You’ll be prompted to enter:
Company Registration Number (CRN)
Registered company name
Ensure both match the Companies House register exactly.
Double-check before submitting.
Once submitted:
HMRC processes your request
The UTR is sent by post
It is delivered to your registered office address
Delivery usually takes 15 working days.
Look for:
Corporation Tax payment reminders
Filing notices
Penalty letters
Your UTR is usually displayed at the top.
If you’ve filed before, your UTR will appear on previous CT600 returns.
Your accountant may also have it on file.
Avoid these common issues:
Entering incorrect company names
Using an outdated registered office address
Applying for a dissolved company
Expecting the UTR by email
Remember: HMRC always sends it by post for security reasons.
Requesting a copy of your Corporation Tax UTR is straightforward. But that’s only one small part of running a compliant limited company.
