Frequently asked questions

What documents do I need to prepare for a Self Assessment tax return?

You will need your P60 or P45 forms, details of any self-employment income, bank interest, dividends, and records of pension contributions. Also gather receipts for allowable expenses and any charitable donations. A qualified accountant in Merstham can help you organise these documents efficiently.

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

ACCA and ICAEW accountants are highly trained professionals who understand HMRC regulations thoroughly. They can identify legitimate deductions, ensure your personal tax return is submitted correctly, and advise on tax planning strategies to reduce your overall liability. Their expertise helps avoid costly errors and HMRC enquiries.

What is the deadline for filing a Self Assessment tax return?

The paper filing deadline is 31 October following the end of the tax year, whilst the online filing deadline is 31 January. Missing these dates results in automatic penalties. Engaging a local accountant in Merstham ensures your return is filed on time and in the correct format.

Do I need to complete a Self Assessment tax return if I am employed?

If you are employed and your tax is deducted through PAYE, you typically do not need to file a return. However, if you have additional income from self-employment, rental properties, or savings interest above certain thresholds, HMRC may require you to submit a personal tax return. An accountant can clarify your obligations.

Can a Merstham accountant help with VAT and Corporation Tax as well?

Yes, many accountants in Merstham offer comprehensive services including VAT returns and Corporation Tax preparation. These professionals can manage your business tax affairs alongside your Self Assessment, ensuring consistency and compliance across all filings.
