# Corrections log

Dated public log of calculator formula fixes, schema corrections, and tax-year updates. We log confirmed errors instead of silently rewriting pages.

## Quick answer

Report a suspected error via /contact with the URL, inputs, and a primary source. Verified mismatches are fixed in the engine, the page date is updated, and a row is added here. We do not pay for takedowns and we do not hide corrections inside changelog fluff.

## US tax-engine arithmetic on the IRS tax-debt calculator

A band-boundary error in the federal tax-debt helper understated some liabilities. We corrected the engine against IRS Publication 15-T figures for the published tax year and re-tested the worked examples. Pages: /calculators/irs-tax-debt/.

## Removed fabricated AggregateRating from WebApplication schema

A hard-coded 4.7/1,847 AggregateRating had been injected into every calculator’s JSON-LD. No review system exists. The block was deleted site-wide. Structured-data ratings will only return if we collect real first-party reviews.
