Corporation Tax Registration | Company Tax & UTR

Link your company to HMRC’s Corporation Tax system and obtain the necessary references (including UTR) — a timed obligation that starts after formation and does not wait for “the first big profit”.

How remote UK Ltd formation works in practice

A UK Private Limited Company (Ltd) is a separate legal entity registered at Companies House. Non-resident founders can form one remotely through an authorised ACSP. Eteform handles the filing and checks in 24–48 working hours. Six service packages start from £226; the £100 Companies House fee is shown separately.

After incorporation you receive a CRN and digital documents. Many founders then open Wise Business or Revolut Business, set a London registered office if needed, and prepare for Stripe, Shopify or Amazon using matching company details. Annual duties typically include the Confirmation Statement (CS01), accounts, and Corporation Tax registration with HMRC when trading starts. Dormant companies still have lighter filing duties — they are not a full exemption from Companies House.

UK Ltd formation does not grant UK residency or a visa. Eteform guarantees legal, complete execution of every request, and bank or payment-gateway approval when all requirements are fully met — with a correctly filed, transparent entity and Arabic support from order to certificate. Compare packages, read the formation guide, or start your order with clear GBP pricing.

The deadline after formation

Usually you must register the company for Corporation Tax within months of starting to trade or according to HMRC notices. Waiting “until we make a profit” is a common cause of penalties. Even limited activity may start the clock. We set registration to your company’s actual dates, not a feeling of market readiness.

How registration works step by step

  • Gather company data (CRN, address, directors, trading start date)
  • Initial Corporation Tax registration with HMRC
  • Receive/organise the UTR and references
  • Explain the expected first return window
  • Refer to an accountant to prepare the figures if needed

UTR and what it is for

A Unique Taxpayer Reference is a tax reference you use when dealing with HMRC and filing returns. Without organising this file, returns are delayed or updates are rejected. We explain where the number is stored and who uses it (you or your accountant).

Scope of the £75 registration service

  • Initial Corporation Tax registration from company data
  • Explain the expected first return window
  • High-level guidance on the difference between Companies House accounts and the tax return
  • Referral to an accountant to prepare figures if you do not have one

Dormant versus active company

Dormant Accounts are filed with Companies House for a period with no significant accounting activity. That does not necessarily cancel dealing with HMRC about the company’s status. We explain both paths so you do not file Dormant while issuing real invoices — or the reverse.

Profit distributions and tax residence

Drawing profits from a UK Ltd to your personal account is subject to the rules of your country of residence and may be affected by double-tax treaties. The registration page does not replace personal tax advice; we set the framework and point you to a specialist before large distributions.

FAQ about this service

Does registration mean I pay tax now?

Registration activates the file. Tax due is calculated on profits in the later return. It may be zero in a loss-making or dormant period within the conditions.

Who prepares the annual return?

An accountant or tax preparer. We prepare registration and the timetable; the figures are their responsibility unless you contract that explicitly.

I missed the HMRC notice — what should I do?

Do not wait for a second letter. Start registration/settlement immediately; delay increases the penalty. Message us with company details so we can assess the position.

What is the Corporation Tax rate roughly?

Rates change (for example 19% for smaller companies and 25% above certain thresholds with Marginal Relief). We confirm the rate in force with your accountant when you ask — do not rely on an old figure.

Is it different from CS01?

Yes entirely. CS01 is for Companies House; Corporation Tax is for HMRC. Two separate paths with different deadlines.
