Frequently asked questions

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

A CT600 tax return is the standard form used by limited companies to report their Corporation Tax liabilities to HMRC. Every company that is active for Corporation Tax purposes must file a CT600 tax return, even if it has no taxable profits or is dormant. The return covers the company's accounting period and must be submitted within twelve months of the period end.

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

ACCA and ICAEW accountants are highly trained professionals who specialise in company corporation tax filing. They ensure that your CT600 tax return is accurate and submitted on time, helping you claim all allowable deductions and reliefs. They also provide advice on tax planning, ensuring your company remains compliant with HMRC regulations and avoids costly penalties.

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

HMRC imposes automatic penalties for late filing of a company tax return. The initial penalty is £150 if the return is up to three months late, increasing to £300 if it is more than three months late. Further penalties apply for continued delays, and interest is charged on any unpaid Corporation Tax. Professional accountants can help you avoid these penalties by ensuring timely submission.

Can a qualified AAT professional handle my company's tax returns?

Yes, AAT qualified professionals are trained in accounting and tax compliance, and many are fully capable of preparing and filing company tax returns. They have a solid understanding of Corporation Tax and CT600 tax returns, and they work under the supervision of or alongside ACCA and ICAEW accountants. Using an AAT professional from AccountingFirms ensures you receive competent and reliable assistance.

What information do I need to provide for a company corporation tax filing?

To complete a company corporation tax filing, you will need your company's statutory accounts, including the profit and loss account and balance sheet. You will also need details of any capital allowances, charitable donations, and other deductions. Your accountant will guide you on the specific information required, ensuring that your CT600 tax return is accurate and compliant with HMRC requirements.
