Overview

Corporation Tax is a tax on the profits of limited companies and other organizations, including clubs, societies, associations, and unincorporated entities. The current Corporation Tax rate is 19% (as of 2024), though this rate is subject to change, so it's important to stay updated with HM Revenue and Customs (HMRC) announcements.

Key Steps to Paying Corporation Tax

1. Registering for Corporation Tax
   • You must register your company with HMRC for Corporation Tax within three months of starting business operations. This can be done online through the HMRC website.
2. Accounting Period
   • Your company’s accounting period for Corporation Tax is typically 12 months and matches your company’s financial year.
   • The accounting period starts on the day your company starts trading and usually ends on your company’s chosen year-end date.

Calculating Corporation Tax

1. Determine Taxable Profits
   • Taxable profits include trading profits, investment income, and capital gains.
   • Deduct allowable expenses from your total income to calculate taxable profits. Allowable expenses include business running costs, employee salaries, and certain capital allowances.

     • R&D Tax Credits: Relief for companies engaged in qualifying research and development activities.
     • Capital Allowances: Deductions for certain capital expenditures, like equipment and machinery.
     • Loss Relief: Use trading losses to reduce future taxable profits.
3. Prepare and Submit Company Tax Return

   • Include your company’s statutory accounts, computations, and any relevant supplementary pages.
   • File the return within 12 months of the end of your accounting period.

Paying Corporation Tax

   • Penalties may apply for failing to pay on time or for inaccuracies in your tax return.

Tips for Managing Corporation Tax

1. Maintain Accurate Records
   • Keep detailed and accurate records of all business transactions, expenses, and income.
   • Retain these records for at least six years, as HMRC may request to review them.
2. Use Accounting Software
