Frequently asked questions

What is a Self Assessment tax return and who needs to file one?

A Self Assessment tax return is a system used by HMRC to collect income tax from individuals who receive income not automatically taxed, such as self-employment earnings, rental income, or investment dividends. You must file one if your untaxed income exceeds £1,000 or if HMRC specifically asks you to complete a return.

How can an ACCA or ICAEW accountant help with my personal tax return?

An ACCA or ICAEW qualified accountant brings rigorous training and up-to-date knowledge of tax legislation. They can accurately complete your hmrc personal assessment, identify all allowable deductions, and ensure your return is submitted on time. Their expertise reduces the risk of errors and potential penalties from HMRC.

What documents do I need to provide for my Self Assessment tax return?

You will typically need your P60 or P45 forms, bank interest statements, dividend vouchers, records of any self-employment income and expenses, details of rental income, and receipts for charitable donations or pension contributions. A Dorset accountant can advise on exactly what is required for your situation.

What is the deadline for submitting a Self Assessment tax return in Dorset?

The deadline for paper returns is 31 October following the end of the tax year, whilst online returns must be filed by 31 January. For example, the 2024-25 tax year return is due by 31 January 2026. Late submissions incur automatic penalties from HMRC, so timely filing is crucial.

Can a local accountant in Dorset handle both my Self Assessment and business taxes?

Yes, many firms featured on AccountingFirms offer comprehensive services including Self Assessment, Corporation Tax, VAT returns, and payroll. Engaging one accountant for all your tax needs ensures consistency, simplifies communication, and provides a holistic view of your financial position, which can lead to better tax planning.
