Frequently asked questions

What is a Self Assessment tax return?

A Self Assessment tax return is a form used by HMRC to collect income tax from individuals who are self-employed, have untaxed income, or need to report capital gains. It requires you to declare your earnings and claim allowable expenses to calculate the tax you owe.

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

Qualified ACCA, ICAEW, or AAT accountants understand complex tax legislation and can identify deductions you might miss. They ensure your return is accurate and submitted on time, reducing the risk of HMRC penalties and helping you pay no more tax than necessary.

How do I find a reliable accountant in Swanley?

You can use AccountingFirms to browse local professionals who are verified and regulated. The directory allows you to compare firms based on their qualifications, services, and client reviews, making it easy to select a trusted accountant for your Self Assessment needs.

What happens if I miss the Self Assessment deadline?

Missing the HMRC deadline results in an automatic £100 penalty, with further fines if you delay longer. Interest is also charged on unpaid tax. Using a professional accountant helps ensure your return is filed on time, avoiding these additional costs.

Can an accountant help with both personal and business taxes?

Yes, many accountants handle both personal Self Assessment and business taxes such as Corporation Tax and VAT. They can manage your entire tax profile, ensuring consistency between your personal return and your company's filings, which is particularly useful for directors and sole traders.

What information do I need to provide for my tax return?

You will need details of your income from employment, self-employment, investments, and any benefits. You should also provide records of allowable expenses, pension contributions, and charitable donations. Your accountant will guide you on exactly what is required to complete the return accurately.
