Frequently asked questions
What is a Self Assessment tax return and who needs to file one?
A Self Assessment tax return is a system HMRC uses to collect income tax from individuals who receive income not taxed at source. You typically need to file one if you are self-employed, a company director, or have untaxed income from investments or property.
How can an ACCA or ICAEW accountant help with my tax return in Brentford?
An ACCA or ICAEW qualified accountant brings regulated expertise to your Self Assessment, ensuring accurate calculations and compliance with HMRC rules. They identify allowable expenses and reliefs, reduce the risk of errors, and handle correspondence with HMRC on your behalf.
What happens if I miss the HMRC Self Assessment deadline?
Missing the deadline results in an automatic £100 penalty, with further fines and interest added for continued delay. A qualified accountant can help you avoid these penalties by ensuring your return is submitted on time and managing any late filing issues with HMRC.
Do I need to submit a personal tax return if I am employed but have rental income?
Yes, if you receive rental income above certain thresholds or have other untaxed earnings, you must file a Self Assessment tax return. An accountant can help you report this income correctly and claim allowable expenses related to your property letting.
Can a Brentford accountant help with both Self Assessment and Corporation Tax?
Yes, many accountants in Brentford specialise in both Self Assessment for individuals and Corporation Tax for limited companies. They ensure all your tax obligations are met, from personal tax returns to company filings, providing a coordinated approach to your finances.
