File Corporation Tax Return Online

Managing corporate taxes can be a complex and time-consuming task for any business, whether a small startup or a well-established company. At Affotax, we provide a seamless solution to file Corporation Tax returns online, ensuring accuracy, compliance, and peace of mind. 


Our dedicated team of qualified tax professionals is here to make filing Corporation Tax returns straightforward, so you can focus on running your business.


Why is Corporation Tax Filing Important?


Corporation Tax is a mandatory tax imposed on UK companies’ profits. Every UK-registered company, whether active or dormant, must submit an annual Corporation Tax filing to HMRC (HM Revenue and Customs). Failing to do so, or submitting incorrect information, can result in penalties and interest charges.


At Affotax, we understand the nuances of filing a Corporation Tax return, helping businesses meet their tax obligations efficiently and on time.


Process of Filing Corporation Tax Returns


When it comes to filing Corporation Tax returns online, accuracy and punctuality are essential. Our process is designed to be efficient, secure, and compliant with all HMRC regulations:

  • Gathering Financial Data: We collect and review your company's financial records, including income, expenses, assets, and liabilities.
  • Calculating Taxable Profits: Based on the financial information, we calculate the taxable profits for your company, including allowable expenses and any reliefs that may apply.
  • Preparing the CT600 Form: We prepare your CT600 form, ensuring that every detail aligns with HMRC’s standards for accuracy.
  • Online Filing of Corporation Tax Return: Once prepared, we submit your Corporation Tax filing directly to HMRC online, keeping you updated throughout the process.
  • Confirmation and Compliance: After filing, we provide confirmation and retain a record of your submission to support compliance and audit needs.

With Affotax, you can rest assured that your Corporation Tax return is filed correctly, on time, and with full transparency at every step.


UK Corporation Tax Deadlines & Penalties


The deadline for filing your Corporation Tax return is typically 12 months after the end of your company’s accounting period. However, any Corporation Tax owed must be paid within 9 months and 1 day from the end of the accounting period. Missing these deadlines can result in penalties, which can vary depending on how long the payment or filing is delayed.


Penalties for Late Filing & Payment:

  • Late Filing Penalties: If you fail to file your Corporation Tax return on time, penalties can range from £100 to a percentage of the unpaid tax, depending on the length of the delay.
  • Late Payment Penalties: Penalties for late payment are charged based on the amount of tax owed and how long after the deadline the payment is made.
  • Affotax’s Support: We help ensure you meet all Corporation Tax deadlines, avoiding unnecessary penalties and keeping your business compliant.


Who Needs to File a UK Corporation Tax Return?


All UK-registered companies must file a Corporation Tax return. This includes:

  1. Limited Companies: Required to file regardless of profit or loss.
  2. Dormant Companies: Must notify HMRC if they do not have taxable profits but still need to file.
  3. Non-Resident Companies: Companies outside the UK but with UK-based trading activity are also required to file a Corporation Tax return.

Common Challenges in Filing Corporation Tax Returns


For many businesses, filing Corporation Tax returns comes with challenges such as:

  • Understanding Allowable Expenses: Knowing what qualifies as a deductible expense can be complex.
  • Managing Financial Data: Keeping accurate, detailed records of income and expenditures is critical for compliance.
  • Navigating Tax Reliefs and Allowances: Reliefs like the Annual Investment Allowance (AIA) can significantly impact your tax outcome but require careful understanding.
  • Staying Updated with Tax Laws: Corporation Tax rules and rates may change. Affotax ensures that your filings align with the most recent tax regulations.
