Extremely bad service.
Miscalculation and file wrong tax return.
Not taking responsibility to fix the problem.

Ray was great answered any and all of my concerns and questions immediately within 6 hrs even when he was sick! Got me $700 more than I thought I was getting. Very professional and I live in Mass I still trusted and used Sigma so easy and convienant. Would recommend anytime and decent pricing! More...

Thank you for the kind words! Both of us at Sigma are glad we were able to help you receive a nice refund and enjoyed consulting with you. I look forward to working with you in the future

Ray and Effie are very detail oriented and come with a wealth of knowledge from years in large corporate roles. So far its been a great experience having Ray handle both my taxes and consulting on my books. He is working hard to save me every dollar possible with my personal and corporate tax return. More...

Our accounting services include but are not limited to bookkeeping, monthly and quarterly reconciliations, payroll, reviews and accounting system implementations. Our tax services include monthly sales tax, estimated tax, tax planning and year end tax compliance for business and individuals.

A great accountant is one you can trust and one who is straight forward. The CPA's at Sigma have great reputation for telling the clients not only what they want to hear, but what they need to hear. Having a good accountant like Sigma Accountants and Advisors, enables the client to focus your time and attention to your personal or business needs. A great CPA will go above and beyond to save you money and time through efficient accounting and tax services.

The best part about the job is finding new clients and developing strategies to help them increase efficiencies. Seeing our strategies and goals come to fruition together is a great feeling and leaves the client happy and us at Sigma happy.

The partners at Sigma have worked for large accounting and financial firms in NYC for a combined 12 years and during that time have found inefficiencies with how big companies work with their clients. Sigma is inspired and eager to build long lasting relationships with each client so they got together and worked through a business plan where every client can get custom and modern CPA services. The partners enjoy working with clients and developing accounting, tax and financial solutions.

Our clients should choose Sigma because our main focus is client relationships. We will always make ourselves available to you and guide you through all of your financial, accounting and tax needs. If our office can't provide the services you need, we have professional alliances with financial planners, insurance brokers and lawyers. We like to think of our office as a one stop shop.


It is time to start thinking about your 2018 tax returns. Sigma provides a free consultation to go over your specific tax situation to determine how we can provide you tax compliance and advisory services. Every individual and business needs a custom look at their tax details and Sigma does just that. We will provide you guidance and then file your returns in an efficient manner. Once we have all your tax documents we can typically turn around a return within a week and e-file through our modern tax software.
