What customers said about business tax return preparation
Dina and the team were thorough, punctual, and enjoyable to work with getting my business taxes filed and on a rush. I’m happy to have found the CPA I look forward to working with for many years to come.
Been working with Ilir and his team about 5 years now. First few years of our business we bounced around accountants struggling to find a good fit for our small business. Last few years have been Great since we found these guys. I can’t believe it took me this long to get on here and say it. Thanks Ilir!
Michael and his company are the best. Simply the most knowledgeable and easy to work with. What else can I say.
Can always count on Montgomery and Associates to handle all my tax reporting needs.
Montgomery and Associates has helped us with our taxes for years. The team has been wonderful with guiding us throughout the process. The communication from each team member made it a smooth and positive experience.
Handled fillings for multiple entities. Quick and attentive with appropriate follow up (Im sure I was frustrating in my procrastination). Reasonable price and good result.
