Our Expert Corporation Tax Return Services

Corporation tax is a non-negotiable obligation for any UK-registered company. Filing it incorrectly, missing reliefs, or submitting late can lead to unnecessary payments and HMRC scrutiny. We provide exact, planned, and legally sound tax solutions, ensuring businesses pay only what they owe—nothing more, nothing less.

We handle every aspect of corporation tax, from accurate calculations to HMRC compliance and planned tax planning. Our services include:

1. Corporation Tax Return Preparation and Filing (CT600 Submission)

Corporation Tax Return Preparation and Filing (CT600 Submission)

Every limited company must file a CT600 form to report its taxable income, reliefs, and final tax liability. We:

  • Collect and analyze profit and loss accounts, balance sheets, and financial statements.

  • Calculate net taxable profits, ensuring all allowable deductions and reliefs are applied.

  • Submit the return using HMRC-recognized tax software, ensuring compliance with Making Tax Digital (MTD).

Even a minor error in reporting can trigger an HMRC compliance check or an audit. We ensure accuracy, eliminating risks before submission.

Tax Computation and Profit Adjustments

Corporation tax is calculated on adjusted trading profits, not just net earnings. We:

  • Identify and disallow non-deductible expenses that could trigger HMRC red flags.

  • Maximize allowable expenses such as office rent, utilities, business travel, marketing, and salaries.

  • Adjust for capital allowances on equipment, machinery, and R&D investments.

  • Assess loss relief options, carrying losses forward or backward for tax efficiency.

With proper adjustments, businesses can significantly reduce their tax liability while remaining compliant

3. Capital Allowances and Ramped Tax Relief

Capital Allowances and R&D Tax Relief

Many businesses miss out on legitimate tax-saving opportunities. We ensure:

  • Capital Allowances: We apply the correct tax treatment for qualifying assets, including the Annual Investment Allowance (AIA) and Super Deduction Relief.
  • Research & Development (R&D) Tax Credits: For companies investing in innovation, product development, or software solutions, we claim tax relief under the R&D Expenditure Credit (RDEC) scheme.
  • Patent Box Relief: Businesses generating revenue from patented products can qualify for a reduced 10% corporation tax rate.

Claiming these correctly can reduce corporation tax liabilities by thousands of pounds.

HMRC Compliance and Audit Support

Any errors in a corporation tax return can trigger an HMRC compliance check or even a full audit. We:

  • Review returns for accuracy and risk exposure before submission.

  • Handle HMRC inquiries, providing necessary documentation and responses.

  • Assist in resolving tax disputes and negotiating settlements where required.

A tax investigation can disrupt business operations—we ensure our clients are prepared and protected.
