Frequently asked questions

What is a CT600 tax return and who needs to file it in County Antrim?

A CT600 tax return is the form used by companies to report their profits and calculate Corporation Tax liability to HMRC. In County Antrim, every limited company that is active, including those that are dormant, must file a CT600 return, even if they have no tax to pay. The return must include detailed computations and be submitted within twelve months of the end of the accounting period.

How can ACCA or ICAEW qualified accountants help with company corporation tax filing in County Antrim?

ACCA and ICAEW qualified accountants have rigorous training and ongoing professional development, ensuring they are up to date with the latest tax legislation. They can accurately prepare your company tax returns, identify allowable deductions, and ensure compliance with HMRC requirements. Their expertise reduces the risk of errors and penalties, and they can also advise on tax planning strategies to minimise your Corporation Tax liability.

What are the deadlines for filing company tax returns in County Antrim?

The deadline for filing a company tax return is twelve months after the end of your accounting period. However, Corporation Tax must be paid nine months and one day after the end of the accounting period. Missing the filing deadline can result in automatic penalties, so it is essential to engage a qualified accountant early to ensure timely submission and payment.

Are there penalties for late filing of CT600 tax returns in County Antrim?

Yes, HMRC imposes penalties for late filing of CT600 tax returns. The initial penalty is £150, and if the return is still outstanding after three months, an additional £150 is charged. For repeated late filings, penalties can increase to £500 per return. Further penalties apply if the return is more than six months late, so it is crucial to meet the deadlines with professional assistance.

Can accountants in County Antrim also handle VAT and Self Assessment for directors?

Yes, many accountants in County Antrim offer comprehensive services that include VAT returns and Self Assessment for directors. They can manage your VAT registration, submissions, and compliance, as well as prepare personal tax returns for directors.
