Frequently asked questions

What is the deadline for filing company tax returns in Lisburn?

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 instruct a qualified accountant in Lisburn to manage the process for you.

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

An ACCA or ICAEW accountant has the technical knowledge to prepare your CT600 tax returns accurately, ensuring all income and gains are reported correctly. They can identify allowable deductions and reliefs, reducing your Corporation Tax liability. Their expertise also helps you avoid common errors that trigger HMRC enquiries, giving you confidence that your filing is compliant.

What information do I need to provide for my company tax return?

You will need to provide your company's financial statements, including the profit and loss account and balance sheet, as well as details of any director's loans, dividends, and capital allowances. Your accountant may also require information about any disallowable expenses. Providing complete and accurate records helps your accountant prepare your return efficiently and correctly.

Why should I use a professional for company corporation tax filing?

Company corporation tax filing involves complex rules and strict deadlines. A professional accountant ensures your return is filed correctly and on time, minimising the risk of penalties. They can also provide strategic advice on tax planning, helping you legally reduce your tax bill. Using a professional gives you peace of mind and frees up your time to run your business.

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

If you file your company tax return late, HMRC will charge an automatic penalty of £150 for each late return, even if you have no tax to pay. If your return is more than three months late, the penalty increases to £300, and further penalties apply for longer delays. Additional interest will also be charged on any unpaid Corporation Tax.
