Frequently asked questions

What is the deadline for filing company tax returns with HMRC?

The deadline for filing your company tax return is usually 12 months after the end of your accounting period for Corporation Tax. However, you must pay any tax due nine months and one day after the end of the accounting period. Missing the filing deadline can result in automatic penalties, so it is wise to engage a qualified accountant to manage the process.

Why should I use an ACCA or ICAEW qualified accountant for my CT600 tax returns?

ACCA and ICAEW qualified accountants have undergone rigorous training and are bound by professional standards. They possess in-depth knowledge of UK tax law and HMRC requirements, ensuring your CT600 tax returns are accurate and compliant. Their expertise can help you identify allowable deductions and avoid costly errors, giving you confidence that your filing is correct.

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

To complete your company corporation tax filing, you will need your company's financial statements, including the profit and loss account and balance sheet. You will also need details of any expenses, allowances, and reliefs. Your accountant will guide you on the specific documents required and can help you organise your records to ensure a smooth filing process.

Can AccountingFirms help me find a local accountant in Sunningdale?

Yes, AccountingFirms is a directory that connects you with verified accountants in Sunningdale. You can browse local firms, compare their services and read reviews to make an informed choice. The platform was established in 2019 by ICAEW and ACCA accountants, so you can trust the quality of the professionals listed.

What are the penalties for late filing of company tax returns?

HMRC imposes penalties for late filing of company tax returns. The initial penalty is £150 if your return is up to three months late, and it increases to £300 if it is three to six months late. Further penalties apply for longer delays, and interest may be charged on unpaid tax. Engaging a professional can help you avoid these penalties.

How can a qualified accountant help with VAT and Self Assessment alongside Corporation Tax?

A qualified accountant can manage all your tax obligations, including VAT and Self Assessment, in addition to Corporation Tax. They can ensure your VAT returns are filed correctly and on time, and they can assist with your personal Self Assessment tax return if you are a director or shareholder. This integrated approach saves you time and reduces the risk of errors.
