Corrections Policy

Last reviewed: 2026-05-18

BusCalcTools publishes financial calculators and articles read by small business owners across the US, UK, and South Africa. When something on this site is wrong, we want to know — and we want our fix to be visible.

What we treat as a correction

Factual errors — a tax rate, threshold, or rule stated incorrectly anywhere on the site.
Broken calculations— a formula that produces an output inconsistent with the documented “See the formula” box on the same page.
Outdated rates — a benchmark, tax rate, or statutory threshold that has changed since our last review.
Source errors — a citation that no longer resolves, or that points to the wrong primary source.
Misleading framing — language that implies individual financial advice rather than educational guidance.

Typo fixes, broken internal links, and design tweaks are treated as ordinary maintenance and do not appear in the public correction log.

How to report a correction

Email [email protected] with:

The URL of the affected page.
The specific sentence, number, or output that's wrong.
What you believe the correct value or wording should be.
A link to a primary source (IRS, HMRC, SARS, statute, or peer-reviewed publication) where possible.

Response times

Acknowledgement within 2 business days of receipt.
Investigationwithin 7 days for clear-cut issues (a documented rate change, a formula that contradicts its own “See the formula” box).
Investigation within 21 days for nuanced issues (regional edge cases, scope-of-applicability questions).
Correction shipped within 7 days of confirming the error.

How corrections are recorded

Every substantive correction does three things:

The affected page's last-reviewed dateupdates, which also updates the dateModifiedfield in the page's JSON-LD schema for search engines.
A dated entry is added to the public changelog describing what changed and why.
If the original error materially affected an output (a calculator returned a wrong number for a class of inputs), the changelog entry states that explicitly. We don't quietly rewrite history.

What we won't correct

Differences of opinion on benchmarks. Where the site uses an industry-typical figure (e.g. healthy gross margins for a SaaS business), we cite our source. A reasoned disagreement about which benchmark to use is an editorial choice, not a correction.
Output that disagrees with your accountant. Calculators on this site are designed as fast sanity checks, not a substitute for professional advice. If your accountant gives you a different number, your accountant is probably right — they know your full situation and we don't.
Region-mismatch results.When a US user runs a UK tax scenario the calculator returns the right number for the wrong jurisdiction. That's a UX issue we keep working on, not a calculation error.

Editorial independence

BusCalcTools is monetised by display advertising. We have no affiliate relationships with banks, lenders, accountants, ecommerce platforms, or financial-product providers mentioned in our content. See the advertising disclosure for the full monetisation picture. No correction is ever blocked or modified because of a commercial relationship.

Authorship and review

All content is written and reviewed by James Blanckenberg. See the editorial policy for the full standards we hold every page to.
