I have used paylesstax.ie now for 5 years. The system is very simple to use and it has improved over the years. The thing about this company that I like most is that it also has excellent people in the background that are very responsive and helpful. Over the years my tax has become more complex and I have found all my answers from either the system, Declan or Barry. I have never once waited for a reply and I have asked plenty of support or backup questions. They also have a full accounting practice ready to assist any query (international tax treaties, rental income etc). From a cost perspective I do not think it would be possible to match or beat these folks. If you want to get on top of and stay on top of your taxes, this the right system and people for you in my opinion.
