Prime Meridian review
A free web-based option for personal federal and state tax filing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Prime Meridian is a web-based tax preparation service for U.S. personal taxpayers. It combines document uploads with an AI Tax Assistant that asks questions, captures tax information, and produces a draft return with plain-English explanations. The service is designed for returns involving W-2s, 1099s, self-employment, K-1s, investments, rentals, multiple states, and other income sources.
The published Free plan costs $0 and includes AI-assisted tax preparation, federal and state e-filing, K-1 support, and free, unlimited multi-state returns. Users can upload W-2s, 1099s, K-1s, receipts, and other tax documents, while deduction identification helps surface potential deductions. Prime Meridian also includes encrypted tax-document storage and secure cloud processing, making document handling a central part of the workflow rather than an optional add-on.
Prime Meridian is a focused choice for individuals who want no-cost online filing with AI guidance and support for more involved personal returns. Its scope is narrower for users seeking professional involvement: the service does not provide expert review or professional tax advice. It is also limited to the web, with no broader platform or integration ecosystem described. Choose it for self-directed personal filing, especially when K-1s or multiple states are involved; consider an alternative if expert review, business tax preparation, or non-web access is essential.
