Very efficient, friendly and user friendly websites. They meet in person and online! Super happy to have them help with my taxes. Huge sigh of relief.

Nikhil Balakumar

PSA CPA is an incredible firm that can meet both your individual and business tax needs! Sunny (the CEO) and Pervaan (VP of Ops) bring a personalized and thoughtful approach to each client’s needs. I trust them to manage my taxes personally and for my consulting company. Additional benefits are their knowledge of tax compliance for cryptocurrencies. Highly recommend!

Sasanka Sharma

2 years ago , we were looking for an Indian CPA and found PSA CPA based on the Google reviews. Went there to do my 2021 taxes and they charged me $1800. The tax preparer Mr. Sonny Singh was in such a hurry that he made me write a Check of $10k plus to the state of Maryland. Which I did . We made $12k plus extra estimated tax payment already to the state of Maryland by then , and he had all the information. 

McKenzie Figur

This is my second year having my taxes done here! Incredibly professional, knowledgeable, and efficient! Also willing to help with tax related questions throughout the year. Such a pleasant experience – 10/10 recommend this business!!

Ryan Boasi

Quick and professional, Sonny is a prince amongst PCAs.

Ephraim Atkinson

The people were a real pleasure to work with. Great communication, and had the patience to work through a tricky issue. Tax season was far less stressful this year. Will recommend to others.

Corey McMillan

Reniece Weaver

5 stars for these rockstars!! Sonny and his team have been amazing. From my very first phone call, I experienced kindness and professionalism. I was short on time and was able to get an initial appointment the same day. I inquired at 9am and was scheduled for the afternoon!

Jamila Boddie

Andrew Hill

Sonny helped me navigate the sale of my elderly parents 2nd home. He was super patient, took the time to make sure that I understood all of the different taxes and ways that you can help legally reduce your tax burden. Why 5 stars? Sonny treated my family like his family.

Robert Pierce III

PSA CPA has been doing the taxes and assisting with the financials review of my employer for a number of years. I have personally been working with Sonny for 2 years now and I would highly recommend PSA CPA and Sonny for a great deal of accounting and financial needs.

Phil Bewerunge

Two years ago, I was in the market for a tax CPA and found Sonny’s practice on Yelp. I wanted a more strategic relationship with my tax preparer – I needed someone who would see the big picture, provide proactive guidance, and maintain a very personal relationship with his clients to the point where they wouldn’t hesitate to call him with any questions.

Emil Pagliarulo

I’ve used Sonny for a couple of years now. Best random search I ever did! I had a pretty complicated tax situation – far beyond what I would normally do myself – and Sonny handled it efficiently and expertly. Communication is always fast and clear, and my refund spoke for itself. Highly recommended!

William Johnston

Prompt and dedicated support when I needed it the most


We started doing our taxes here after they became too complicated to do ourselves online. He is a very friendly person and quick to respond. So far the process has been very easy and it’s one less thing for me to think about during the year.

Jeanette Dexter

Wonderful service! Back next year!


Why did we only just now have Sunny do our taxes? Heard from a friend this CPA firm was worth the time. 100% true- we are seriously kicking ourselves for only coming here in 2022. Why stress at home for weeks/months when you can make an appointment, spend a bit of time collecting your tax docs, and then deal with a pro like the CPAs at PSA.

Saurav Sharma

I have been using Sonny for the last couple of years. He is responsive and knowledgeable about the taxation domain. Sonny is personable and prepared for our appointments. We certainly recommend him.

Courteous communication, deep knowledge on all taxation issues combined with accuracy, professionalism and punctuality, it is a service hard to beat today. I have been their customer for over 35 years and never had a complaint

Jessica Brown

I’m very grateful to have Sonny as my accountant. He advised me to apply for the PPP, I didn’t think I qualified. Without him, I never would have realized I could have access to that income. He is really knowledgeable and smart, but most of all, he’s a great human being.

Dash Dalrymple

I am extremely happy with my decision to visit Sonny and his team! In the short time I met with Sonny, he was able to thoroughly answer all of my questions and he even explained some nuances in tax laws that were new to me–even after hours of extensive online research on my own.

Shahnam Yazdani

Sonny is always responsive and very knowledgable. He has been such a great help throughout the years. I would highly recommend him and his team!

Damone Brown

This is my family’s first experience using Sonny for our taxes after having a bad experience elsewhere. He is extremely knowledgeable and a joy to work with. He was kind, personable, and prepared for our appointment. We certainly recommend and plan to never go anywhere else. Thank you!

Jorge Pardo

I started working as an independent contractor 2 years ago, and I need help navigating the tax laws that applied to my new situation. Sonny took the time to explain what expenses could be claimed and what options I had to minimize my tax liability. He is knowledgeable, very easy to talk with and dedicated to provide excellent service to his clients. I am a happy returning customer.

Mary Crenshaw

He is not only very knowledgeable but understands and listens to what you have to say. By far the best COA ever! Give him a try he is truly amazing!! AAA Mary Crenshaw

I found Sonny through Yelp and Google; both had stellar reviews of his services so I shot him a Yelp message to ask about an appointment.
