Dimov Tax is a full-service US CPA firm. It's done-for-you and quote-based — not self-serve PFIC software.
Dimov Tax is a US-based CPA firm that handles a wide range of work — expat returns, business and partnership returns, equity comp, and crypto — on a done-for-you basis. Pricing is quote-based and scales with complexity. Atamatax is narrower by design: self-serve software focused on the expat case, with PFIC/Form 8621 handling built in at a flat price and a free draft before you pay.
Who Dimov Tax is for
Dimov fits people who want a CPA to take the whole thing off their plate, or who have tangled business, equity, or crypto situations that benefit from hands-on professional work. If you mainly want an expat return with foreign accounts and PFICs done accurately, without a custom quote, Atamatax covers that lane.
