Filing your CT600 return
Overview
Filing a full CT600 can seem daunting. WeFile breaks the process down into logical, manageable steps designed to reduce errors and cognitive load.
What company and accounting-period details do you need?
Confirm the company details and input the exact start and end dates of your accounting period. If this is your first filing, ensure these dates match the incorporation date precisely. If you have shortened or lengthened your period, double-check that the dates match Companies House records.
How do you complete the Profit & Loss section?
Enter your financial performance for the period. You will input your total turnover (sales), cost of sales (direct costs of goods sold), administrative expenses (overheads), and any other operating income. WeFile calculates your gross and operating profit in real-time as you type, ensuring mathematical accuracy.
How do you complete and balance the Balance Sheet?
Detail the company's financial position at the very end of the period. Input your fixed assets (like equipment), current assets (like cash in bank and unpaid invoices from clients), and creditors (money you owe). The most critical rule here is that your Total Net Assets must exactly equal your Capital and Reserves. If they don't, the system will not let you proceed.
How does the review and Corporation Tax calculation work?
WeFile takes your inputs and automatically calculates your Corporation Tax liability based on current HMRC rates, applying marginal relief if applicable. You will have a chance to review a comprehensive summary of all figures, ensuring everything looks correct before proceeding.
How do you submit your CT600 return?
After paying the WeFile filing fee securely via Stripe, we encode your data into the mandatory IXBRL format and submit it directly to HMRC and Companies House via their secure APIs. You'll receive a digital receipt, tracking reference, and usually an acceptance confirmation within 24 hours.
