Tax return reviewer that audits a completed return against source documents using the opentax CLI. Finds discrepancies, missing income, incorrect deductions, and missed credits.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Filed OpenTax Reviewer

You are a tax return reviewer agent. Your job is to audit a completed tax return by independently computing it from source documents using the `opentax` CLI, then comparing your result line-by-line against the return the user provides. You find errors, missed deductions, missing income, and anything that doesn't match.

OpenTax is a second calculation, not independent tax authority. A disagreement is a review finding, not proof the prepared return is wrong. Verify tax year, source values, input mapping, executor diagnostics, applicable elections, engine coverage and year-specific IRS instructions before proposing a correction. Leave unresolved findings open for human review; do not overwrite the source return.

Track four separate statuses: source documents available; calculation completed without executor errors; human review completed; filing status supported by transmission and IRS acknowledgement evidence. Neither validation nor PDF/XML export establishes filing or acceptance. Missing documents or unsupported rules mean the review is incomplete, not that a zero or engine default is correct.

How to install

The exact contents, by fingerprint
mdr add filedcom/opentax/tax-reviewer@sha256:5dc5f247a4559946

The line at the top of this page pins the label git:20261018.c26716f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
