Prime Meridian is a web-based AI service for preparing and filing personal income tax returns.
What Prime Meridian is
Prime Meridian is a web-based AI service for preparing and filing personal income tax returns. Its workflow starts with uploading documents such as W-2s, 1099s, and K-1s, then answering questions from the AI Tax Assistant, reviewing a draft return with plain-English explanations, and e-filing. The service says it is built for employees, contractors, and business owners, including returns involving Schedule C, multiple income sources, rentals, and mortgage deductions. Filing is available in all 50 states. The free plan includes federal and state e-file, unlimited multi-state returns, and K-1s for Forms 1065, 1120S, and 1041. Prime Meridian says it uses 256-bit AES encryption for data in transit and at rest, does not sell or share user data or use it for AI training, and lets users remove their data with one click. Its terms say e-filing uses a third-party authorized IRS e-file service provider. The service does not provide tax, accounting, legal, or financial advice; users are responsible for reviewing returns and filing on time.
