How and When to Register for Corporation Tax in the UK

Registering for Corporation Tax is a crucial step for every company operating within the United Kingdom. Most companies in the UK register for Corporation Tax and PAYE as an employer simultaneously while registering with Companies House. Registration is required for companies that have registered with Companies House but have not registered for Corporation Tax, companies registered by post, companies using an agent, or those using third-party software. If you've already registered for Corporation Tax, you can sign in to the HMRC online services to file your company tax return or make a payment​​.

How and When to Register for Corporation Tax in the UK

When to Register for Corporation Tax

Most companies in the UK register for Corporation Tax and PAYE as an employer simultaneously with their registration at Companies House. However, if you've registered your company by post, through an agent, or using third-party software, you'll need to register for Corporation Tax separately.

The key point to remember is that you must register within three months of starting to do business. This includes activities such as buying, selling, advertising, renting a property, and employing someone. If you're unsure about what counts as starting to do business, it's advisable to check with the relevant authorities. Be aware that there may be penalties for late registration.

How to Register for Corporation Tax

To register for Corporation Tax, you'll need to sign in to your business tax account. Follow the guidance provided in your account to complete the registration process. You'll need your company’s Government Gateway user ID and password to sign in. If you don't have a user ID, you can create one when you sign in.

Additionally, you'll need your company’s 10-digit Unique Taxpayer Reference (UTR). This is posted to your company address by HM Revenue and Customs (HMRC) within 14 days of the company being registered with Companies House (incorporated). If you did not receive your UTR after registering your company, you can request it online.

Information to Provide to HMRC

During the registration process, you'll need to provide HMRC with your company’s registration number, the date you started to do business (your company’s first accounting period will start from this date), and the date your annual accounts are made up to.

Here Is a Step-By-Step Guide On How to Register for Corporation Tax in 2023.

Step 1: Determine Your Eligibility

Before you start the process, ensure that your business is required to pay Corporation Tax. Generally, all limited companies based in the UK or foreign companies with a UK branch or office need to pay Corporation Tax.

Step 2: Set Up Your Company

If you're starting a new business, you'll need to set it up with Companies House. When you register, you'll get a 'certificate of incorporation'. This confirms your company legally exists and shows the company number and date of formation.

Step 3: Register Within Three Months

You must register for Corporation Tax within three months of starting to do business. This includes buying, selling, advertising, renting a property, and employing someone. You can face penalties if you fail to register within this period.

Step 4: Use the Government Gateway

To register, you will use the UK government's online services, accessible via the Government Gateway. If you do not have a user ID and password, you will need to create one.

Step 5: Provide Your Company's Information

During registration, you'll need to provide the company's details. This includes:

  • The date you started to do business (your 'accounting period' for Corporation Tax will start from this date)

  • The date that you'll make your annual accounts up to

  • The company's registration number (given to you when you registered with Companies House)

  • The main address where you do business

  • The type of business you run

Step 6: Appoint an Agent

If you want someone else to deal with HM Revenue and Customs (HMRC) on your behalf, like an accountant, you can appoint them as your agent. This can be done during the registration process.

Step 7: Keep Records

Once registered, you must keep proper records of your business income, costs, and expenses. These will be used to prepare your Company Tax Return and calculate your Corporation Tax.

Step 8: Pay Your Corporation Tax

You are responsible for calculating how much Corporation Tax you owe and paying it. This must be done within 9 months and 1 day from the end of your 'accounting period' - which is usually your financial year.

Step 9: File a Company Tax Return

Lastly, you need to file a Company Tax Return, even if you make a loss or have no Corporation Tax to pay. This should be done within 12 months after your accounting period ends.

Following these steps will help you navigate the process of registering for Corporation Tax in the UK. Remember, it's essential to comply with these regulations to avoid penalties and ensure your business operates smoothly. Please note that the process and requirements may vary slightly, so always refer to the official UK government website or consult with a tax professional to understand your specific obligations.

After Registration

Once you've registered, HMRC will inform you of the deadline for paying Corporation Tax. Remember, you'll need to file a Company Tax Return, even if you make a loss or have no Corporation Tax to pay.

Finding your UTR after Registration

If you enrolled for the Corporation Tax online service, you can find your 10-digit UTR in HMRC online services. You can also find it in all letters from HMRC. You'll need your UTR if you contact HMRC about Corporation Tax or send your Company Tax Return using commercial software.
