Frequently asked questions

What is a CT600 tax return and why is it important?

A CT600 tax return is the form used to report a company's Corporation Tax liability to HMRC. It must be filed within twelve months of the end of your accounting period. Failing to submit on time can result in penalties, so it is essential to use a qualified accountant who can prepare and file your CT600 accurately.

How can an ACCA or ICAEW accountant help with company corporation tax filing?

ACCA and ICAEW accountants have rigorous training and ethical standards, ensuring your company corporation tax filing is correct and compliant. They can identify allowable deductions, manage deadlines, and communicate with HMRC on your behalf, reducing the risk of errors and penalties. Their expertise is invaluable for complex tax situations.

What are the penalties for late Corporation Tax filing?

HMRC imposes automatic penalties for late Corporation Tax filing. The first penalty is £150, with additional penalties if you file more than three months late. If you are more than six months late, a further £150 is charged, and in some cases, a tax-geared penalty may apply. Professional accountants help you avoid these costs.

Can an accountant help with both Corporation Tax and Self Assessment?

Yes, many accountants in South East London are qualified to handle both Corporation Tax for your company and Self Assessment for your personal income. This is particularly useful for directors and sole traders who need to manage multiple tax obligations. A single professional can ensure all returns are consistent and timely.

How do I choose the right accountant for my company tax returns?

When choosing an accountant, look for recognised qualifications such as ACCA, ICAEW, or AAT, as well as experience with company tax returns. You should also consider their familiarity with your industry and their communication style. AccountingFirms allows you to compare providers based on credentials and client reviews, making the selection process easier.

What records do I need to keep for Corporation Tax purposes?

You must keep accurate financial records, including income, expenses, and any capital allowances. HMRC requires you to retain these records for at least six years. A qualified accountant can help you organise your records and ensure they meet HMRC standards, which simplifies the filing process and protects you in the event of an enquiry.
