Frequently asked questions

What is included in a Self Assessment Tax Return service?

A Self Assessment Tax Return service typically includes the preparation and electronic submission of your annual tax return to HMRC, calculation of tax due, advice on allowable expenses and reliefs, and assistance with payments on account. The accountant will also review your income from employment, self-employment, property, or investments to ensure full compliance.

How do I know if an accountant is properly qualified?

Qualified accountants will be members of recognised professional bodies such as ACCA, ICAEW, or AAT. These organisations require members to follow strict ethical codes, complete continuing professional development, and hold appropriate insurance. You can verify an accountant's credentials by checking the register on the relevant body's website.

What happens if I miss the Self Assessment deadline?

Missing the Self Assessment deadline results in an automatic £100 penalty from HMRC, with further penalties accruing after three months. Interest is also charged on any unpaid tax. A qualified accountant can help you file a late return and may assist in negotiating a time-to-pay arrangement if you cannot settle the full amount immediately.

Can a accountant help with HMRC enquiries or investigations?

Yes, an accountant can represent you during an HMRC enquiry or investigation. They will review your tax return, gather supporting documents, and communicate with HMRC on your behalf. Having professional representation reduces stress and ensures your rights are protected throughout the process, which can be particularly important for complex cases.

Do I need to use an accountant if my tax affairs are simple?

Even for simple tax affairs, an accountant can save you time and help you claim all the reliefs and allowances you are entitled to. They ensure your return is accurate, reducing the risk of errors that could trigger an HMRC check. Many people find the cost of professional help is outweighed by the peace of mind it provides.

How do I choose the right accountant in Thames Ditton?

Start by browsing local firms on AccountingFirms and comparing their qualifications, specialisms, and client reviews. Consider whether they have experience with your type of income, such as self-employment or property rental. It is also wise to check their fee structure and whether they offer a free initial consultation to discuss your needs.
