Whether it’s your first time working with a chartered certified accountant, or you’ve used one before, you might still have a few questions before taking your next steps. We’ve prepared a list of frequently asked questions to help you.

What is a chartered certified accountant?
A chartered certified accountant must pass many rigorous exams, meet experience requirements and comply with a strict code of ethics. There’s no other finance professional that’s better equipped to help you with business and personal tax and finances.

I'm just starting my business. Do I need a chartered certified accountant now?
There's never a bad time to engage a chartered certified accountant. If you’re starting your own business, it’s a good idea to contact us BEFORE you start. We’ll guide and assist you during the difficult start-up processes. You’ll be better organised and it’s often cheaper and easier to start with us from the outset, rather than fixing problems later.
Do you offer free initial consultations?
No, sorry but we don’t. We believe that we can add value from the outset. However, you are welcome to email us your question so we can give you a no-obligation estimate of our fees to answer your questions. We’re also happy to discuss your questions by telephone before you engage us.
Are you a member of any professional tax or accounting organisations?
Yes, our principal is a member of the Association of Chartered Certified Accountants (ACCA) and a registered Tax Agent with Inland Revenue.
How do you stay abreast of latest tax rules?
Tax legislation is constantly changing. We keep our skills and knowledge current by attending seminars/webinars, reading professional journals and newsletters and by meeting strict continuing professional education which our professional bodies monitor.
May I contact you after you’ve completed my return?
Yes, of course! We’d be delighted to hear from you and hope to develop an ongoing business relationship with you. Regardless of what type of tax or business-related questions you have, or even other finance-related questions, please contact us. If we don't know the answer, we’ll refer you to someone who will.
Will you retain my tax records?
Yes, we retain a copy of your tax return and our accompanying working papers for seven years. We recommend that you also retain your own copy and original documents for the same period.
