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

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

We engaged Taxkey to provide tax advice on a company sale. Mairéad is thorough and professional, and throughout the engagement demonstrated excellent knowledge of the tax implications for shareholders. Mairéad provided critical advice and recommendations on the structure of the company sale and legal agreements documenting the sale, along with guidance on completing the relevant tax returns.

Two Irish Shareholders

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!

Declan Kennedy Reiken & Associates

I recently sold an Irish property whilst living abroad and had many years worth of tax returns which needed to be submitted to revenue. It was an extremely overwhelming and stressful situation to be in which was made much easier after acquiring Taxkey's services and dealing directly with Mairead throughout the whole process. I would highly recommend Taxkey and thank them for their knowledge, quick response times and professionalism throughout.

Irish individual living abroad

I have been extremely satisfied with the professional, timeous and courteous service I have received from Taxkey since our arrival in Ireland in 2021

Ian Everitt-Penhale
