Sharon and her team at Masler & Associates, Inc. is a great asset and team to have when preparing our financials and taxes. Sharon and Lauren have been doing our accounting and taxes for years and we know we are in the best of hands.

I have been working with Sharon Masler and Masler & Associates, Inc. for over a decade. I would go no where else. Great attention to details. The staff is top notch.
Kenneth Williams
Sharon showed a great depth of knowledge, was paying attention to details and was very responsive. Our tax returns are not the simplest ones. She was able to master the nuances and helped me with decision-making. Thanks to her, today is March 12, and we have already completed the return, ahead of the tax-time rush. I just hope she does not decide to retire while I have a continuing need for tax returns over the next two decades.

The result of the audit, you ask? Masler & Associates, Inc. turned an upside-down situation right-side up. Long story short, they negotiated our huge tax bill into a substantial refund!

Masler & Associates Inc. is an excellent accounting & tax preparation firm. Sharon has been doing our taxes for years and is always very thorough in making sure we claim every deduction allowable. Our taxes are complex due to working out of country and also owning a business. Masler & Associates knows how to handle all the minutia. Most importantly, everyone at the firm is “down to earth” and very helpful. I would highly recommend them to everyone: from folks that have simple returns to those with the most complex tax situations.
