Tesseract-Tax Cloud™

Tesseract-Tax Cloud™ is your tax return in your pocket: send in your tax documents, review what was read from them, see how your return is computed, and sign it for e-filing. It works on its own or with your CPA firm, from the same account you use at platform.knottheory.ai.

SEND YOUR DOCUMENTS
Scan W-2s, 1099s and other forms with the camera into a clean PDF, pick photos or files, or email them to your engagement's private address. Each document is read for you and shown field by field, so you can confirm or correct the values before they count.

SEE YOUR RETURN, AND WHY
Your estimate shows the federal and state results separately and explains each step of the computation, line by line, from your own documents.

CHECK A RETURN PREPARED ELSEWHERE
Already have a completed Form 1040 from another preparer? Start a Return Check, upload it with the documents it was prepared from, and see whether every line agrees with an independent computation, with each difference explained. A Return Check never files anything.

ANSWER THE INTERVIEW
Household, dependents and the questions your documents do not answer, with suggestions drawn from your documents that you confirm before anything is used.

SIGN AND FILE
Review your Form 8879, confirm your identity, and sign on screen by typing or drawing your signature, or upload a copy signed on paper. KnotTheory.ai Inc. is an Authorized IRS e-file Provider.

PRIVATE BY DESIGN
Documents are encrypted, every access is recorded, and your Social Security number is never stored on your phone.

An account is required. Tax years 2024 and later are supported. Tesseract-Tax Cloud is tax software, not a CPA firm; reviews by a CPA are performed by the CPA firm you work with.
