Frequently asked questions
What documents do I need to prepare for my self assessment tax return?
You will need your P60, P45, bank interest statements, dividend vouchers, records of any self-employment income and expenses, and details of pension contributions or charitable donations. An accountant can help you organise these documents efficiently.
How can an ACCA or ICAEW accountant help with my HMRC self assessment?
An ACCA or ICAEW qualified accountant understands HMRC rules and deadlines thoroughly. They can prepare your tax return accurately, identify allowable expenses, and ensure you do not miss important reliefs, reducing the risk of penalties or HMRC enquiries.
What is the deadline for filing a personal tax return in Upon-thames?
The online filing deadline is 31 January following the end of the tax year. Paper returns must be submitted by 31 October. A local accountant can remind you of these dates and help you file on time to avoid late-filing penalties.
Can a VAT-registered business also use self assessment services?
