Frequently asked questions

What is Corporation Tax and who needs to file a company tax return?

Corporation Tax is a tax on the profits of limited companies and other organisations. Every limited company must file a company tax return, known as a CT600, with HMRC for each financial period. Even if you have no tax to pay, you must still submit a return. Professional accountants in Hillingdon can help you prepare and file this accurately.

How can an ACCA or ICAEW accountant help with CT600 tax returns?

ACCA and ICAEW accountants are highly qualified professionals who understand the complexities of CT600 tax returns. They ensure that your company corporation tax filing is completed correctly, on time, and in line with HMRC regulations. They can also advise on allowable deductions and reliefs to minimise your tax liability while remaining fully compliant.

What are the deadlines for filing company tax returns with HMRC?

The deadline for filing a company tax return is usually 12 months after the end of your accounting period. However, you must pay Corporation Tax within nine months and one day of the end of your accounting period. Missing deadlines can result in penalties. A qualified accountant in Hillingdon can help you manage these dates and avoid unnecessary fines.

Why should I use a verified accountant from AccountingFirms for my tax filing?

Using a verified accountant from AccountingFirms ensures that you are working with regulated professionals who meet high standards. The directory was built by ICAEW and ACCA accountants, so you can trust the quality of the firms listed. They can help you with company tax returns, VAT, and Self Assessment, providing expert advice tailored to your business.

What is the difference between Corporation Tax and Self Assessment?

Corporation Tax is paid by limited companies on their profits, while Self Assessment is the system for individuals, including sole traders and partners, to report their income. Both require accurate reporting to HMRC. If you run a limited company, you need to file a CT600 return. A qualified accountant can help you understand which obligations apply to you.

Can an accountant help me with VAT and Corporation Tax together?

Yes, many accountants in Hillingdon are VAT-registered and can manage both VAT and Corporation Tax for your business. They can help you register for VAT, prepare VAT returns, and ensure your company corporation tax filing is accurate. This integrated approach saves time and reduces the risk of errors, keeping your business compliant with HMRC.
