Comparison · updated monthly
Dimov Tax is a full-service US CPA firm. It's done-for-you and quote-based — not self-serve PFIC software.
Dimov Tax presents CPA-led tax services; verify its current credentials, scope, and quote directly. Atamatax is narrower self-serve software: its diagnostic and supported on-screen calculations are free, while generating draft forms and worksheets is paid.
Who Dimov Tax is for
Atamatax fits users who want to self-prepare supported foreign-account and PFIC inputs. It does not handle foreign business forms, promise complete crypto or equity-compensation treatment, or include a CPA; verify Dimov's current service scope directly.

Bottom line
Atamatax supports a narrower self-serve foreign-account and PFIC workflow, with open items identified and no e-file or professional review. Situations involving a business, partnership, complex equity compensation, or crypto fall outside that promise; verify another provider's current scope directly.
