A Guide on How to Register for Corporation Tax in the UK

Understanding corporation tax

Before jumping into the registration process, let's first understand corporation tax. In the UK, corporation tax is levied on a company's profits, which include its trading profits, investment profits, and capital gains. As a business owner in the UK, any company or business needs to meet its obligations and contribute to the country's revenue. 

Who needs to register for corporation tax?

It is essential to know if your business falls into the category of registering for corporation tax because only some businesses are required to register for corporation tax. Simply put, if your business is making a profit, it has become obligatory for you to register for corporation tax, and also if:

• You are operating as a limited company
• You are operating as a partnership with at least one individual who is not a UK resident
• You have started to trade as a sole trader, and your business has grown to become a limited company
• You have a non-profit organisation that makes a profit

A step-by-step guide on how to register for corporation tax

Here is a step-by-step guide on how to register for corporation tax online in the UK

Obtain your Unique Taxpayer Reference (UTR)

The first thing to go for is obtaining a UTR, a key identifier in all your tax-related activities, from HM Revenue & Customs (HMRC). You can get a UTR by registering your company with Companies House. Once you get it through your registered office address within 15 days, you can find it in your tax account in the HMRC app under "your details" or "self-assessment" tab.

Activate your corporation tax online account

After obtaining your UTR, the next step is activating your corporation tax online account through the HMRC website. The corporation tax online account will be your go-to for managing your tax affairs, making payments, and submitting results.

Provide Company Details

The next step is to gather the required details of your company, like:

• Your company registration number (CRN)
• Your Unique Taxpayer Reference (UTR)
• Your business's registered address
• Your business's contact details
• Your business's start date
• The date your annual accounts are made up to.

Submit these comprehensive details, including your company's legal structure, business activities, and financial year-end date. This information helps HMRC accurately assess your tax liability.

Determine your accounting period

An accounting period is the timeframe for calculating your company's profits and losses. Once you have decided on your company's accounting period, remember to keep accurate records of your financial transactions. This is a legal requirement and essential for correct tax calculations.
