Frequently asked questions

What is a CT600 tax return and who needs to file it?

A CT600 tax return is the form used by limited companies to report their taxable profits to HMRC. Every company that is active for Corporation Tax purposes must file a CT600 tax return, even if it has no tax to pay. This includes companies that are dormant or have made losses. Filing is required annually, and deadlines apply from the end of the accounting period.

Why should I use a qualified accountant for company corporation tax filing?

Qualified accountants with ACCA, ICAEW, or AAT accreditation have the technical knowledge to prepare accurate company corporation tax filing. They understand complex tax rules, allowable expenses, and reliefs that can reduce your tax bill. Using a professional also ensures your CT600 tax return is submitted correctly and on time, avoiding penalties and reducing the risk of an HMRC enquiry.

How can AccountingFirms help me find an accountant in Islington?

You can browse local firms, compare their services, and read profiles to find a professional who matches your needs. The platform was built by ICAEW and ACCA accountants, so you can trust the quality of the listed professionals. Simply search for your requirement and review the available options.

What are the penalties for late filing of a company tax return?

HMRC imposes automatic penalties if your company tax return is filed late. The initial penalty is £100, and further penalties apply if the return remains outstanding after three, six, and twelve months. Additional daily penalties may also be charged for prolonged delays. To avoid these costs, it is essential to meet the filing deadline, which is usually twelve months after the end of your accounting period.

What is the difference between Corporation Tax and Self Assessment?

Corporation Tax is a tax on the profits of limited companies and other organisations, while Self Assessment is the system used by individuals, sole traders, and partnerships to report their income and pay tax. If you run a limited company, you must file a company tax return for Corporation Tax. If you also receive personal income, you may need to complete a Self Assessment tax return separately.

How do ACCA and ICAEW accountants ensure compliance with HMRC?

ACCA and ICAEW accountants are bound by strict professional standards and must keep up to date with changes in tax legislation. They have the expertise to prepare accurate company tax returns, calculate Corporation Tax correctly, and submit returns to HMRC on time. Their training ensures they understand HMRC requirements, helping you avoid errors, penalties, and potential investigations.
