Frequently asked questions

What is a Corporation Tax Return and who needs to file one?

A Corporation Tax Return, also known as a Company Tax Return, is a document that limited companies must submit to HMRC each year. It reports the company's profits, gains, and allowable deductions, and calculates the tax due. Any company that is incorporated and trading must file a return, even if it has made a loss or has no tax liability. Failure to file on time can result in penalties and interest.

Why should I use a qualified accountant for my Corporation Tax Return?

Qualified accountants who are members of ACCA, ICAEW, or AAT have the expertise to prepare accurate returns, identify tax savings, and ensure compliance with HMRC rules. They can handle complex areas such as capital allowances, group relief, and R&D claims. Using a regulated professional reduces the risk of errors, penalties, and HMRC investigations, and provides peace of mind that your tax affairs are in order.

How can I find a reputable accountant in Sidcup?

You can use AccountingFirms.co.uk to browse and compare qualified accountants in Sidcup. The directory lists verified, regulated firms and professionals, allowing you to filter by specialism, location, and client reviews. This helps you make an informed choice based on transparent information. AccountingFirms was established in 2019 and built by ICAEW and ACCA accountants, so you can trust the listings.

What information do I need to provide for my Corporation Tax Return?

To prepare your Corporation Tax Return, your accountant will need your company's financial records, including profit and loss statement, balance sheet, bank statements, invoices, receipts, and details of any capital assets. They will also require information on director's loans, dividends, and any other income or deductions. Providing complete and accurate records helps ensure a timely and correct submission to HMRC.

Are there deadlines for filing Corporation Tax Returns?

Yes. For a private limited company, the Corporation Tax Return must be filed within 12 months of the end of the accounting period. The tax itself is usually due 9 months and 1 day after the end of the accounting period. If you use an accountant, they will help you meet these deadlines. Late filing leads to automatic penalties from HMRC, starting at £100 and increasing over time.

Can an accountant help if HMRC opens an enquiry into my tax return?

Yes. If HMRC opens an enquiry into your Corporation Tax Return, a qualified accountant can represent you and handle all correspondence. They will review the enquiry, prepare the necessary documentation, and negotiate with HMRC on your behalf. This can significantly reduce stress and help achieve a favourable outcome. Accountants listed on AccountingFirms are experienced in dealing with HMRC enquiries and compliance checks.
