Filing the CT600 form is one of the most important responsibilities for any UK limited company. We focus on making business tax simple so you can meet your obligations with confidence and clarity. This guide will explain what the CT600 form is, why it matters, and how to stay compliant with HMRC.

What is the CT600 Form?
The CT600 form is the official corporation tax return required for every active limited company. Even if your company makes no profit or owes no corporation tax, you must still submit a CT600 form to HMRC. Accurate reporting helps your business remain fully compliant and avoids unnecessary penalties.
Before you begin preparing your CT600 form, it is important to gather all relevant financial information for the accounting period. This ensures accuracy and helps HMRC clearly understand your business activity.
You will need
- Final statutory accounts
- Profit and loss figures
- Balance sheet information
- Details of expenses and tax reliefs
- Capital allowance information
- Calculations of corporation tax liabilities
The CT600 form contains several key sections that cover your company information profits tax adjustments and any claims for relief. Each section must be completed correctly to reflect your true tax position.
Common challenges include
- Entering inconsistent or incorrect figures
- Forgetting disallowable expenses
- Missing supplementary CT600 schedules
- Filing the CT600 form after the deadline
