Corporation Tax Registration (UTR Support)

If you have recently formed a limited company, you need to register for Corporation Tax with HMRC and obtain your Unique Taxpayer Reference (UTR). This service takes care of the registration, checks the details HMRC rely on, and confirms you are correctly set up for future Corporation Tax filings and payments.

More information

What Corporation Tax Registration (UTR Support) covers

Getting Corporation Tax registration right from the start helps you avoid missed deadlines, lost post, and confusion about what HMRC expect. This service is designed to get your company registered cleanly and to give you clear next steps.

  • Confirming whether and when you need to register (based on when the company starts trading)
  • Collecting the required company and contact details for HMRC
  • Completing the Corporation Tax registration process with HMRC
  • Handling common issues (for example, delays, missing letters, or mismatched details)
  • Confirming your UTR has been issued and recorded
  • Providing a simple summary of key deadlines and what you will need to do next

When this service is most useful

This support is a good fit if you are:

  • Newly incorporated and ready to start trading
  • Already trading but not sure whether HMRC have your company on record
  • Waiting for a UTR letter and need a plan to move things forward
  • Setting up a company for a contract, agency work, consulting, ecommerce, or a trade business and want compliance handled properly

How the process works

You will be guided through a short, structured process to keep things moving.

  1. Initial check: confirm your incorporation details and when trading started (or will start).
  2. Information request: you provide the minimum details needed to register and to ensure HMRC contact details are correct.
  3. Registration submission: we complete the Corporation Tax registration steps with HMRC.
  4. Confirmation: once HMRC issue the UTR, you get confirmation and a clear explanation of what it is used for.

What happens after you receive your UTR

Once your UTR is in place, you can focus on running the business with a clearer view of your compliance timetable. If you want ongoing support, the next steps usually include bookkeeping setup, tracking income and costs, and planning ahead for your first year end, statutory accounts, and the Corporation Tax return (CT600).

Frequently Asked Questions

Do I need to register for Corporation Tax if my company is not trading yet?
You normally register when the company starts trading, not just because it exists. If you are unsure what counts as “trading”, we can review your situation and advise on the right timing.
How long does it take to get a UTR from HMRC?
Timescales vary, but it is often within a couple of weeks after registration. If it is delayed, we will check the status and help resolve common causes.
What information do you need to register my company?
Typically we need your company details from incorporation, the trading start date, and the correct HMRC contact information. If anything does not match HMRC records, we will tell you what needs correcting.
Can you help if I have missed the Corporation Tax registration deadline?
Yes. We can register the company as soon as possible and explain the likely next steps. If HMRC raise queries or penalties, we will help you respond with the right information.
Is Corporation Tax registration the same as registering a company with Companies House?
No. Incorporation with Companies House creates the company, but Corporation Tax registration is a separate step with HMRC. The UTR comes from HMRC and is used for Corporation Tax reporting.
