Reverse Tax Calculator corrects material errors that could mislead users about a formula, example, calculator output, source note, or tax-advice boundary.
Correction work is part of the site's trust system. A user should be able to report a problem and understand how the report will be reviewed.
What Counts as a Correction?
A correction may be needed when a page includes:
- an incorrect reverse tax formula;
- a worked example with the wrong number;
- a tax factor that does not match the displayed rate;
- an outdated or overly broad rate note;
- a broken official-source link;
- a calculator label that could mislead users;
- wording that presents an estimate as official tax advice;
- a typo that changes meaning;
- missing risk context around rounding, exemptions, mixed rates, or taxability.
What Counts as a Clarification?
A clarification improves understanding without changing the underlying fact or formula.
Clarifications may include:
- rewriting a paragraph for plain language;
- adding a rounding note;
- adding an example with cleaner numbers;
- improving a heading;
- adding an internal link;
- explaining when a formula applies;
- adding a warning about mixed receipts.
Clarifications may not need a visible correction note if the original page was not materially wrong.
Review Workflow
When a report arrives, the editorial team reviews:
- the page URL and section named in the report;
- the exact number, phrase, formula, link, or source note;
- the calculator behavior, if the report involves a result;
- the Methodology;
- the relevant official source, if a rate or rule is involved;
- whether the issue affects one page, a shared template, or multiple calculator outputs.
Formula and example reports may be routed to the listed reviewer because calculation errors can affect user trust quickly.
Severity Levels
| Severity | Example | Typical action |
|---|---|---|
| High | Wrong formula, wrong worked example, unsafe advice wording | Correct as soon as practical and review related pages |
| Medium | Outdated official link, unclear rate context, missing rounding note | Update the page and add source or scope context |
| Low | Typo, formatting issue, minor wording improvement | Fix during normal editorial maintenance |
Visible Correction Notes
A visible correction note may be added when an error materially affected the meaning, calculation, or user decision path.
A visible note may not be added for spelling, formatting, link cleanup, wording improvements, or examples that were clarified without changing the underlying answer.
What to Include in a Correction Report
Use the Contact page and include:
- the page URL;
- the heading or calculator mode;
- the value, formula, phrase, or source link that may be wrong;
- the result you expected;
- any official source that supports the report;
- whether the receipt or invoice has mixed rates, exempt items, discounts, shipping, tips, or fees.
Do not send private tax returns, full receipts with personal details, account numbers, government IDs, payroll files, or confidential client records.
What a Correction Cannot Do
A correction can fix site content. A correction cannot decide a user's tax position.
Some reported differences are caused by transaction-specific facts, such as line-level rounding, local tax, product taxability, marketplace collection, exempt items, or receipt formatting. In those cases, the page may be clarified even if the calculator formula is already correct.
