Tax Preparation Review from Parhum Moshki
Dimov Tax was exceptionally helpful and fair-priced when assisting my family with complex tax questions that involved cross-border considerations. They made sure all of our filings strictly adhered to IRS regulations while maintaining the highest standard of quality. It gave us complete peace of mind knowing everything was handled professionally and completely by the book!

Tax Preparation Review from Рубен Газарян
This is easily the finest tax firm I have ever worked with. As a long-term client who grew up outside the United States, I find the American tax system incredibly complex and confusing. However, Kirill Solntsev and George Dimov made my highly complicated 2025 tax return feel completely manageable. Kirill’s exceptional professional support, patience, and meticulous attention to detail were incredible throughout the entire process. They offer top-tier individual tax planning and filing services at a great price point. I wish them continued success and look forward to remaining a loyal client for many years to come!

Elisa Ramundo’s Review from Google

Elisa Ramundo’s's Review Sourced from Google
Had an initial consultation with the firm after sending them detailed documentation. While the accountant was professional and courteous during our call, I was later informed they had no capacity for new clients and wouldn't be able to take on work until Spring 2025. This information should have been communicated before scheduling the consultation and requesting documents. While I appreciate their eventual honesty, this approach wasted time for both parties and doesn't reflect well on their business practices. Scheduling consultations when you know you can't take on new clients is not good client service.

Uptown Body Contouring's Review Sourced from Google
Misleading, dishonest and greedy. I was originally told my tax preparation would be£1750. I then received a bill for £2500 for a seven page boiler plate generic memo regarding tax advice -which amounted to a newsletter. After over a year of receiving harassment emails and bills, I paid the £2500 and never use them for tax preparation, for fear of further “advice” and trumped up fees. A good decision on my part to not throw good money after bad. In summary, I paid £2500 just to part ways. I feel like a fool for being ripped off
