What Is Corporation Tax and Why You Should Register?

Corporation tax is charged on the profits of limited companies operating in the UK. Every limited company is required to pay corporation tax on its taxable profits. The applicable corporation tax rate depends on the profits your business makes during a financial year.

This is a legal obligation for all limited companies. HMRC requires all limited companies to register for corporation tax within three months of starting business activities. Business activities include buying or selling goods or services, advertising, hiring employees, or renting property.

HMRC Corporation Tax Setup Process

The HMRC corporation tax setup process involves several important steps. First, you need to have your company information organised. Second, you should understand your corporation tax obligations. Finally, you must complete the registration process using the correct HMRC channels.

  • Information You Need

To register for corporation tax, you need the following information:

Company registration number from Companies House

  • Company name and registered address
  • Date of commencing business activities
  • Accounting period dates for your company
  • Director and company secretary details
  • Nature of your business activities

This information helps you complete the process more quickly and accurately. Providing accurate information also reduces the need for corrections later.

  • The Three-Month Registration Window

HMRC allows three months from the start of your business activities to register. This deadline is non-negotiable. “Starting business activities” has a specific meaning under HMRC rules.

You have begun if:

  • You buy or sell goods/services
  • You advertise your business
  • You employ staff
  • You rent or purchase business premises

Simply incorporating your company does not count as starting business activities. However, once you have undertaken any business activity, the clock begins ticking.

How to Register for Corporation Tax: Step-by-Step Process

The corporation tax registration procedure involves a series of steps. Follow these steps, and you will register for corporation tax successfully.

Step 1: Register Your Company with Companies House

First, incorporate your limited company with Companies House. This is a step that precedes corporation tax registration. Moreover, you will get a certificate of incorporation and a company registration number. This information is important. You will need it to complete your HMRC corporation tax registration. Alternatively, you can notify HMRC by post using form CT41G.

Step 2: Notify HMRC of Your New Company

Once you have incorporated your company, you need to notify HMRC of your new company. You can do this online through the HMRC website. The online process is quicker. In addition, you will get instant confirmation of your registration. Go to the HMRC website. Next, click on “Tell HMRC about a new company.” Follow the online procedure. Fill in your company information correctly.

Step 3: Receive Your Unique Taxpayer Reference (UTR)

After you register for corporation tax, HMRC will process your application. A few weeks later, you will receive your Unique Taxpayer Reference (UTR). This is a 10-digit number that will identify your business for tax purposes.

HMRC will also send this to your registered company address by post. You must keep your UTR number secure. You will need this for all future tax communications and submissions. Your UTR number will arrive within 2-3 weeks. However, this may take longer during peak times.

Step 4: Activate Your Corporation Tax Online Account

Once you have your UTR number, you can activate your online account. This will allow you to handle your corporation tax online. Moreover, you will also be able to submit your returns and payments online. You can activate your online account by visiting the HMRC website and choosing “Corporation Tax” services.

What’s Next After You Register for Corporation Tax in the UK?

Registration is only the first step. Later on, you are required to comply with several other obligations, such as:

  • File Your Corporation Tax Return

Each year, you are required to submit a Company Tax Return (CT600). This document shows your company’s profit and your tax liability. You must submit it within 12 months of the end of your accounting period. Late submission will result in penalties. So, always keep track of all deadlines.

  • Pay Your Corporation Tax Bill

You have to pay your corporation tax bill nine months and one day after your accounting year ends. You can pay your corporation tax bill online, by bank transfer, or by sending a cheque. Setting aside funds throughout the year helps avoid cash flow issues when payment is due.

  • Maintain Accurate Records

The HMRC demands that you maintain accurate business records. Your business records must contain information about your income, expenses, and tax calculations. Furthermore, you must maintain these records for at least six years.

Accurate business records make it easy for you to file your tax returns. Additionally, accurate business records will help you during HMRC audits.
