Frequently asked questions
What is the deadline for filing company tax returns in Isleworth?
The deadline for filing company tax returns is usually 12 months after the end of your accounting period. However, you must pay Corporation Tax within nine months and one day of that period. A qualified accountant can help you meet these dates and avoid penalties.
Why should I use an ACCA or ICAEW accountant for my CT600 tax returns?
ACCA and ICAEW accountants are recognised for their high professional standards and technical expertise. They are trained to handle complex Corporation Tax matters and can ensure your CT600 tax returns are accurate and submitted on time. Their knowledge reduces the risk of errors and HMRC penalties.
What information do I need to provide for my company tax return?
You will need your company’s financial statements, including profit and loss accounts, balance sheets, and details of any capital allowances. Your accountant will also require information about directors’ salaries, dividends, and any other income or expenses. Providing complete records helps ensure an accurate filing.
Can an accountant help with both Corporation Tax and Self Assessment?
Yes, many accountants in Isleworth are qualified to handle both Corporation Tax and Self Assessment. They can manage your company tax returns while also preparing personal tax returns for directors and shareholders. This integrated approach ensures consistency and helps you take advantage of all available reliefs.
What are the penalties for late filing of company tax returns?
HMRC imposes automatic penalties for late filing of company tax returns. The initial penalty is £150, and further penalties apply if the return is more than three months late. Additional fines are charged for prolonged delays, and interest accrues on unpaid Corporation Tax. Professional assistance helps you avoid these consequences.
