Frequently asked questions
What is included in a Self Assessment tax return service?

Why should I use an ACCA or ICAEW qualified accountant for my tax return?
ACCA and ICAEW qualified accountants undergo rigorous training and adhere to strict ethical standards. They have in-depth knowledge of HMRC regulations and tax law.

Can a tax return accountant help with HMRC enquiries or audits?
Yes, an experienced accountant can represent you during HMRC enquiries and audits. They will review your records, prepare responses, and communicate with HMRC on your behalf. This support reduces stress and ensures your tax affairs are presented correctly to the authorities.
Do I need to submit a Self Assessment tax return if I am employed?
