    Great experience with filing my tax returns. Been going to the firm for a few years now and it's…read morealways been a good experience. My return isn't super straightforward, there are kids, houses, investments (domestic and international), + a few other random things and it's been such a straightforward process. Answer a survey. Provide the documentation. Everything is handled. The team is also very responsive and willing to hop on calls if I need to talk through anything. Will definitely continue to go to them for my accounting needs, including any things beyond my tax returns that might pop up. Pricing is incredibly fair and honestly a great value at the price point.

    I've been a client of Dimov Tax for nearly 10 years, but my recent experience has been extremely…read moredisappointing. During the past five years, I've noticed a clear shift in how the firm operates--communication has declined, staff turnover has increased, and overall service quality has dropped. After paying nearly $1,800 upfront for my 2025 business and personal tax returns, I experienced over a month of delays with little to no clear communication. Despite multiple follow-ups, I was repeatedly asked for information I had already provided, which showed a lack of internal coordination. On top of that, I was asked to sign an engagement letter late in the process, which was not properly delivered or explained. As a client of nearly 10 years, it made no sense to receive a generic engagement letter outlining services I've long been familiar with. There also appears to be a high turnover of staff. I was reassigned multiple times, and each new person seemed unfamiliar with my account, leading to redundant questions and confusion about my LLC structure. It felt like I had to restart the process repeatedly. It's also extremely difficult to get George Dimov on the phone, and emails often go unanswered. At this point, he comes across as an absentee owner, with much of the work seemingly outsourced to staff abroad who are not aligned or familiar with long-term clients. For a firm handling time-sensitive financial matters, that level of disconnect is frustrating. Even more concerning, there was a separate incident involving a former employee, Bob Liu, who went rogue and took client information, including mine. He processed one of my tax returns independently, and to this day I have never received a copy of that return. I had to notify George myself, as he was not aware of the situation. This directly impacted me by delaying a construction loan process I was pursuing with a bank. Most recently, after having over three months to prepare my returns, the firm still filed my tax return incorrectly. That was the final straw for me, and I ultimately decided to terminate my relationship with them. I also ended my payroll services with them. Despite paying $100 per month automatically for 38 months, they claimed I owed an "outstanding balance of $5,700 for 38 months of services." This was completely false, as I have proof of every payment. This situation highlights the disorganization of the firm and the constant turnover of staff who clearly are not aligned or aware of long-term client accounts. Overall, I can no longer recommend this firm, especially for clients with multiple entities or complex tax situations. P.S. The reviews here feel misleading. I've noticed that the owner is quick to respond publicly to reviews, yet does not follow up with his actual clients. If you're considering working with this firm, feel free to reach out to me--I'd be happy to discuss my experience further and share supporting documentation. As a result of the delays and mishandling of my account, I was also charged a late-filing penalty by the IRS.

    I found Gerstain on Google and went with them because they were close by my house and I had an…read moreinitial positive conversation with their team. Unfortunately, I had a very negative experience with them once I signed on for them to do my taxes. They made a total of 5 errors on both my personal and business returns, costing me $3,000+ that I didn't think I would have to pay. They were constantly trying to get me off the phone when I asked them to explain things to me, and didn't want to spend the time to walk through what they needed and what the return entailed -- which would have prevented some of the errors they made. Overall, customer service as abysmal and they made carless errors (like not including my w2 income on my business return), which ultimately cost me thousands of dollars. DO NOT USE THEM!

    I have been going here for decades and when their raised rates, I tried H&R Block. Don't--they are…read morenot easy to work with. I had not understood that Gerstein's is now offering more services like consultations on retirement distribution, which is well worth it. Thankfully, they reviewed my taxes, made some great suggestions, and I will be staying with them in the future. They are extremely easy to work with and understand customer service as well as they understand the complexities of taxes. The fact they are offering more customer service and important pre-tax season consultations (so you know what to plan for) is great news.

During these years, we NEVER experienced any problems with her or any of her staff members. On the contrary: we've been very satisfied with the level of service and communication they've been providing to us. Iryna is a very smart, sharp and honest professional. She attends continuing education seminars and conferences all over the country annually. Her office applies the latest technologies in their work, which makes everything easier, more organized, protected, faster and less expensive for the client. Iryna is on top of the latest tax updates; she sends out all sorts of reminders to her customers along side with personal emails to make sure all the deadlines are met, payments scheduled, nothing missed. The response time frame is unlike all the other accountants we ever dealt with: if not within an hour, then within 24 hrs for sure (which I like very much!) During Tax season she likes to stay in touch even more: by sending all kind of reminders and preparation lists, following up and making sure everything is to a T. Every month during payroll time, her office makes sure our bank account is good to go for any kinds of withdrawals to avoid insufficient funds fees and such. I enjoy reading her monthly newsletters - not too long and very informative. We highly recommend Iryna's Tax services to any individual or company!
