      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 Gerald Triplett

      Working with the team at Dimov Tax has been a fantastic experience. I have relied on them for my filings over the last four tax years, and I always feel confident knowing they genuinely look out for my best interests. They are dedicated, reliable, and consistently advocate for their clients!

      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!
