Frequently asked questions

What is included in a Self Assessment Tax Return service?

A Self Assessment Tax Return service typically includes preparing and filing your annual tax return with HMRC, calculating tax owed, identifying allowable expenses, and advising on tax planning.

Why should I use an ACCA or ICAEW accountant for my tax return?

ACCA and ICAEW accountants are highly trained and regulated by professional bodies. They adhere to strict ethical and technical standards, ensuring your tax return is prepared correctly. Their expertise reduces the risk of HMRC enquiries and helps you claim all legitimate reliefs.

What happens if I miss the Self Assessment deadline?

Missing the deadline results in an automatic £100 penalty from HMRC, with further fines if you delay longer. Interest also accrues on unpaid tax. Engaging a professional early ensures your return is filed on time and accurately, avoiding these costly consequences.

Can an accountant help with HMRC enquiries or investigations?

Yes, a qualified accountant can represent you during HMRC enquiries or investigations. They will review your records, prepare responses, and communicate with HMRC on your behalf. This reduces stress and ensures your rights are protected throughout the process.

Do I need to file a Self Assessment if I am employed?

You may need to file a Self Assessment if you have additional income, such as from self-employment, rental properties, or investments. An accountant can review your circumstances and advise whether a personal tax return is required, ensuring you remain compliant with HMRC rules.
