Tax Returns; preparation and filing

I have had Cotton prepare and file my tax returns (and my married daughters and families) for more than 15 years. He and his staff have always done a perfect job and it sure relieves a lot of stress when there are so many more wonderful ways to spend your time. I highly recommend you have him do the same for you and your families.

Happy Tax Client

I have had only wonderful, professional, and reliable service from Cotton. I know my taxes will be handled without issue or delay. He has helped me with both simple and complicated matters with kindness. Even in the busiest time of the tax season, he responds to my questions and concerns quickly and pleasantly, which makes me feel certain that I am more than just another form to be filled out. Both myself and family plan to work with him for years ahead!

Mr. Mather and his staff have been wonderful to work with

When I started my own (very) small business, one of the two most invaluable pieces of advice I got was to get an accountant. The other was to get Cotton Mather. Mr. Mather and his staff have been wonderful to work with. There seems to be genuine concern on their part for the financial well being of my business and my family. All of this despite the fact that I would guess I am one of the smallest clients of this firm. I have never felt as though any question I have asked is unimportant. The few times when there have been issues, the staff has gone out of their way to help rectify the situation quickly. I cannot recommend someone more highly to help you, your business and your employee(s) - even if you are the only employee.

Cotton easily tackles tough tax situations

Cotton and his staff are knowledgeable, personable, and professional. My taxes are by no means "ordinary" but things get done quickly, with accuracy, and with sound professional advice along the way. I really wouldn't trust anyone else with such important work.

Pittsburgh's BEST Tax Service - Hands Down!

Cotton has gone out of his way to help us with our taxes. He has helped us through job transitions, adoption, sending kids to college, and changing careers. He is always timely, approachable, very knowledgeable, and quick to go digging for more information when needed. He has been a HUGE blessing to us over the years.

Happy Customer of 15+ years

Cotton Mather CPA & his staff have been serving my needs expertly and timely for better than fifteen years. My career was largely in international trade finance and likewise financial analysis. My knowledge and experience is my basis for judging and engaging Mather. Thus I am confident to recommend his service as right on the mark. He has so proven that to me.

Cost Effective Yet Extrodinarily Accurate

Cotton Mather has been our corporate CPA since 2006. Before that, I have served on a board of company with Cotton the Corporate Treasurer. My respect for his job performance lead to offering him the opportunity to our company’s work. We have two corporate entities (one manufacturing and the other real estate management) which benefit from his advise and tax work. Cotton has also taken on the tax work for many of our stockholders. He is very conscientious and has proven to be cost effective. Cotton also serves as the independent trustee on three family trusts. I highly recommend him.
