Frequently asked questions

What is included in a Self Assessment Tax Return service in Newhaven?

A Self Assessment Tax Return service typically includes the preparation and filing of your annual tax return with HMRC, calculation of tax due, and advice on allowable expenses. Professionals also help with income scheduling, capital gains reporting, and ensuring you claim all available reliefs and allowances.

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

ACCA and ICAEW accountants are regulated by professional bodies, meaning they adhere to strict ethical and technical standards. They have in-depth knowledge of tax legislation and can identify savings you might miss. Using a qualified professional reduces the risk of errors and HMRC penalties.

How do I find a reliable accountant for HMRC self assessment in Newhaven?

You can browse the AccountingFirms directory to compare local accountants who specialise in HMRC self assessment. Each listing provides details on qualifications, services, and client reviews. This allows you to select a professional who matches your specific needs and budget.

Can an accountant help with a personal tax return if I am self-employed?

Yes, accountants regularly assist self-employed individuals with personal tax returns. They help organise your business income and expenses, ensure correct classification, and advise on National Insurance contributions. This support is vital for meeting HMRC deadlines and avoiding fines.

What happens if I miss the Self Assessment tax return deadline?

Missing the deadline results in an automatic £100 penalty from HMRC, with further charges if you delay longer. An accountant can help you file late and negotiate with HMRC if there are reasonable excuses. However, it is always best to submit on time to avoid additional costs.

Do I need to keep records for my tax return even if an accountant prepares it?

Yes, you are legally required to keep accurate records of all income and expenses for at least five years after the tax return deadline. Your accountant will need these records to prepare your return correctly. Maintaining organised records also helps if HMRC decides to review your submission.
