Testimonials

I have engaged the services of Taxkey for a number of years as an external tax consultant to our small accountancy firm. Mairead is very professional, personable & a pleasure to deal with. Her technical expertise on complex tax issues is second to none. Whether undertaking a specific body of work or offering a second opinion, her advice has always been very thorough, accurate & always provided in a timely manner. I would have no hesitation in recommending the services of Taxkey.

Juanita Mahon Juanita Mahon Accountancy & Tax

We engaged the services of Taxkey to guide us through tax planning as well as a VAT review and guidance, for our company, now 20 years in business. It has proved to be very timely and well worth investment and we would highly recommend Mairead Hennessy. We found her to be an excellent business consultant, her breadth of knowledge in relation to the subject, left us in no doubt that we were in good hands and felt confident that she would guide us through the complicated terrain. She did a thorough job of listening well, gathering the information from us and then responding with a thorough and in-depth analysis for us to review. Coupled with her expertise, we found Mairead to be very personable, a clear communicator, both in her reports and in person, and she went to great lengths to make all of the information accessible to the lay person. She addressed all of our issues and any further questions that we had arising out of the consultation. I recommend Mairead without hesitation.

Maria Sheanon Roche Martin

We consult with Taxkey when we come across a tax issue that is outside the scope of our in-house expertise, or when we want a second opinion about a technical tax issue. We have always found Mairéad’s advice to be concise, accurate, to the point and provided in a timely and cost-efficient manner. We highly recommend Mairéad

Declan Long Long Accountants Limited

Kane Bergin & Company used the services of Taxkey on a tricky tax assignment in 2019. We found Mairéad to be very professional, courteous and practical in dealing with us and our client. We would have no hesitation in using Taxkey in the future or recommending their services

Austin Bergin Kane Bergin & Company

Mairéad recently completed a body of work for us relating to VAT on the sale of our company’s commercial property. We found Mairéad to be attentive, practical and capable of guiding us smoothly through the various VAT related complexities of the transaction.

Martin O’Donnell Nuhall Retail Services Limited

Mairéad and the team at Taxkey were brilliant to engage with on our R&D Tax credit. Helped us to understand what was valid R&D expenditure and worked with us every step of the way, producing our technical case and financial accounts for our claim. Would wholeheartedly recommend.

Eamonn Costello patientMpower

As a Sole Practitioner the services of Taxkey have given me the exact reassurance I require in relation to any tax issue. Mairead is always quick to respond and her advice is always excellently measured with all Tax-Heads for any issue given thorough consideration.

Ger Kirwan GK Accounts

Mairead Hennessy is a super accountant. Smart, professional and a pleasure to deal with. I would highly recommend Mairead to anyone looking for an accountant.

Luke Hanahoe Hanahoe & Hanahoe Solicitors

I was introduced to TaxKey by my own accountant when I had a particularly difficult situation that needed immediate attention. Mairead and her team really ‘stepped up to the plate’ and not only concurred with the opinion, but offered a slightly differing view which, when taken into account reduced the final tax due even more. I am more than happy to recommend TaxKey, as I have done in the past. Her exposure and experience and value for money is second to none!
