Overview:

Essential primer on Corporation Tax

Corporation Tax, also known as corporate tax, is the mandatory tax contribution a business makes, based on its profits.

This tax includes not only trade profits but also interest on investments and any gains from selling or disposing of assets.

All business must register for Corporation Tax within three months of commencing their business activity.

This activity is not limited to the selling of goods or services; it encompasses any act that plants the seeds for future commerce, such as buying stock, advertising, or renting a property for operations.

Understanding Corporation Tax obligations

Whether it be selling wares or services, advertising to the masses, renting property for operations, or employing staff, profit from these activities make businesses responsible for registering for and subsequently paying Corporation Tax.

Initiating the registration process 

Registering for Corporation Tax is an essential step that involves securing a Unique Taxpayer Reference (UTR) from HMRC.

This process sets the stage for your business to engage with tax obligations and aligns with the registration for other taxes like Value Added Tax (VAT) and PAYE for employers, should they be requisite.

To embark on this journey online, you must first create a Government Gateway user ID and password, followed by submitting your company details to HMRC.

The timeline for registration

The clock for registering for Corporation Tax starts ticking from the moment business activities commence, be it trading, advertising, or hiring employees. Within three months of these business activities, your business must register. Failing to do so can lead to penalties that escalate with each passing day, starting from a seemingly minor £100 for a single day’s delay.

Necessary documentation

To register for Corporation Tax you will need all necessary documentation, including your company’s registration number, a distinct identifier issued by Companies House. Other essential information includes:

  • The date when the business began any commercial activity
  • The company’s financial year-end date
  • The CT41G form, showing that your company is a UK tax resident and bearing the UTR number.

Navigating HMRC’s online services

The Government Gateway online portal is the entry point into HMRC’s online services, a portal where businesses can fulfil their tax obligations. To access these services, you will need a user ID and a secure password.

Accessing your Government Gateway user ID

The Government Gateway user ID is typically received via email during the initial HMRC service registration. Should you lose your username or password, the ‘Problems signing in’ web page should help you recover them

Understanding your Unique Taxpayer Reference (UTR)

The Unique Taxpayer Reference (UTR) is the distinguished identifier that HMRC uses to recognise individuals and companies within the UK tax system.
The UTR can be found in your HMRC online services account, or on any official correspondence, such as letters from HMRC.

Preparing for your Company Tax Return

As the fiscal year ends, attention turns to the preparation of your Company Tax Return. According to the timeline set by HMRC, Corporation Tax payments are due nine months and one day after the close of the accounting period, while the filing of the Company Tax Return must occur within 12 months of the same period’s end.

Record-keeping requirements

For new companies, the management of PAYE as part of their payroll is an essential step after registering as employers with HMRC. This task involves calculating taxes due for payroll using each employee’s tax code and reporting and paying any deductions to HMRC every month.

Additionally, registered VAT businesses must submit VAT returns, usually every quarter, and settle VAT bills online. Corporation Tax calculations require maintaining comprehensive documentation such as receipts and invoices to track a business’s income and expenses.

Meeting deadlines and avoiding penalties

The consequences of late or incorrectly filed tax returns begin at £100 for being just one day late, and escalate with each passing day, including accruing interest on overdue amounts.
Companies must file a Company Tax Return regardless of whether the business has Corporation Tax to pay.

Even after the initial filing, adjustments can be made within 12 months of the statutory filing date, but errors uncovered beyond this time must be corrected following HMRC’s specific procedures.

Addressing special cases in Corporation Tax

Dormant companies, recognized by HMRC as inactive, are exempt from the regular filing of tax returns and the payment of Corporation Tax provided they have ceased trading and do not partake in other income-generating activities. Dormancy is a status granted to companies that:

  • are not trading
  • have not begun to trade
  • owe less than £100 as an unincorporated association
  • are flat management companies.

However, certain income-generating activities will remove a company’s dormating state, such as:

  • trading, which can result in trading profits
  • renting
  • selling assets
  • holding assets that can produce profits

Once your company is no longer dormant, you will need, once more, to file a Corporation Tax return and pay Corporation Tax

Financial year alignment and accounting periods

For Corporation Tax purposes, a company’s financial year typically mirrors its accounting period, the 12-month duration that annual accounts cover..

However, should a company’s business activities commence or cease partway through the year, or if other significant events occur, an adjustment to the accounting period may be required to maintain compliance with tax regulations.

This can sometimes lead to the necessity of filing two tax returns if a company’s first financial year surpasses the 12-month mark due to its immediate commencement of trade.

The information provided during Corporation Tax registration assists HMRC in determining the company’s tax accounting period, thereby establishing the critical dates for filing and payment.

Why professional advice matters

  • Focus on your company’s growth and profitability

  • Achieve significant savings through efficient tax planning.
