Magnetic is an agentic AI tax preparer that completes entire 1040 returns end-to-end, with each return backed by a material-accuracy guarantee – if it’s not right, it’s free. Firms simply forward the messy documents received from taxpayers, and Magnetic compiles the workpapers, reasons across complex inputs, and prepares the whole return directly in the firm’s original software file. Every return is reviewed by an EA/CPA before final delivery.
