What Our Clients Say
Don't just take our word for it - hear from our satisfied clients
I was introduced to TaxKey by my own accountant when I had a particularly difficult situation that needed immediate attention.
Mairéad 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
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.

Ian Everitt

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 Mairéad throughout the whole process.
I would highly recommend Taxkey and thank them for their knowledge, quick response times and professionalism throughout.

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.

Mairéad 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.
would have no hesitation in recommending the services of Taxkey.
Juanita Mahon
Accountancy & Tax
Our recent experience with Taxkey was outstanding. Taxkey were recommended to us by our accountant when we were changing the status of our business.
As this was all new to us, we depended on the professional services of Taxkey to guide and advise us through the process. Being able to get their services purely online and just as effectively and efficiently was fantastic.
We met with Mairéad Hennessy initially and Aidan Twomey after that. Both Aidan and Mairead gave us plenty of time to consider their advice and encouraged us to get back to them with any questions or further clarification as required, which we did and the advice we got was clear and practical.
We would highly recommend this company and therefore would have no hesitation in recommending Aidan and Mairéad and the services of Taxkey should you need them.
