Frequently asked questions

What is the deadline for filing a Corporation Tax return?

The deadline for filing a Corporation Tax return is usually 12 months after the end of your company's accounting period for Corporation Tax. However, you must pay any Corporation Tax owed nine months and one day after the accounting period ends. Missing the filing deadline can result in automatic penalties, so it is essential to keep track of these dates and seek professional advice if needed.

What information is required for CT600 tax returns?

To complete CT600 tax returns, you need details of your company's income, profits, allowable expenses, and any reliefs or deductions. You must also include information about capital allowances and any losses carried forward. The form requires a breakdown of your Corporation Tax calculation, and you may need to submit supplementary pages for specific items such as loans to participators or controlled foreign companies.

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

An ACCA or ICAEW accountant brings in-depth knowledge of tax legislation and HMRC requirements. They can accurately prepare and file your company tax returns, ensuring all allowable expenses are claimed and your tax liability is minimised. They also provide strategic advice on tax planning, help you respond to HMRC queries, and keep you compliant with changing regulations, giving you peace of mind and saving you time.

What are the penalties for late filing of Corporation Tax returns?

Penalties for late filing of Corporation Tax returns are automatic and scale with the length of the delay. If your return is one day late, you incur a penalty of £100. If it is three months late, the penalty increases to £200. After six months, you face a further penalty of 10% of the unpaid tax, and after 12 months, another 10% may be charged. Additional penalties apply for repeated late filing.

Can an accountant also handle VAT and Self Assessment for directors?

Yes, many accountants offer a comprehensive service that includes VAT returns and Self Assessment for directors. They can manage your VAT registrations, submit VAT returns, and advise on VAT schemes. For directors, they prepare and file Self Assessment tax returns, ensuring all income is declared and tax is paid correctly. This integrated approach ensures all your tax obligations are met in one place.

Why is it beneficial to use a regulated accountant for corporation tax filing?

Using a regulated accountant, such as one who is a member of a recognised professional body like ACCA, ICAEW, or AAT, provides assurance of their competence and ethical standards. They are required to maintain up-to-date knowledge and adhere to strict professional guidelines. This reduces the risk of errors, penalties, and HMRC investigations. Their expertise can also uncover tax savings and improve your overall financial management.
