Editorial Policy

Who produces this content

Content is produced by the TaxYourSalary Editorial Team, which is responsible for the tax engine, the source records behind it, and the written material around it. The team is accountable for the published figures and for the corrections process below. Every salary and hub page carries the editorial byline and the date it was last updated, so a reader can always see when it was last reviewed.

Where the figures come from

No tax rate on this site is estimated, averaged, or copied from another calculator. Every rate sits in a deterministic calculation engine and is traced to a primary source published by the relevant tax authority. Where a source record has been completed, the page it was read from is named and linked on the calculator page itself, together with the date our figures were last compared against it.

Source records are currently published for United Kingdom (HMRC), United States (IRS), Canada (CRA), Australia (ATO), Ireland (Revenue), Germany (BMF), France (DGFiP), Spain (AEAT), Netherlands (Belastingdienst) and India (Income Tax Department).

For markets outside that list we still publish the calculation, but the page states plainly that a permanent citation is still being recorded. We would rather show a documented gap than invent a citation. A market is only listed as sourced once our figures have actually been compared, figure by figure, against the authority's own published rates.

How often figures are checked

Rates, thresholds, contribution ceilings and credits change, usually once a year and occasionally mid-year. When an authority publishes a change, the rate is amended in the engine, which updates every page that depends on it at once — a corrected rate cannot be applied to one page and missed on another. Each source record carries the date of its last comparison and that date is shown to the reader. The site is reviewed ahead of each new tax year for every market it covers. We do not stamp a fresh date on a page without re-reading the source.

How automation is used

This site uses automation, and we think it is better to say so plainly. Salary pages are generated in bulk from the calculation engine and a set of written templates, because there are hundreds of thousands of salary and pay-period combinations and no sensible way to hand-write them all. What automation produces is the arithmetic and the page assembly: the computed figures, the deduction breakdowns, the comparison tables, and the questions a reader is most likely to ask about that salary.

What automation does not do is decide what is true. Rates come from the source records described above, not from a model. Hub content, the guides, the policy pages and this document are written and reviewed by the editorial team. Generated output is checked against the engine before publication, and no figure is published as sourced unless it traces back to a source record.

Editorial independence

TaxYourSalary is funded by advertising. Advertisers and ad networks have no influence over which salaries are calculated, which markets are covered, what the pages say, or how a figure is presented. We do not accept payment to alter a calculation, to state a rate the authority has not published, or to recommend a product or provider.

Corrections

If you believe a figure is wrong, tell us and we will check it against the authority's published rate. Where we have made an error we correct the engine, which corrects every page that uses it, and we update the affected page's review date. Where a source record was missing, we complete it. Where the figure was right, we explain the calculation and the source we used. Corrections are decided on the merits of the source, not on how forcefully the point is put.

Send corrections through the contact page. Include the page you are looking at and, if you can, a link to the published rate you are comparing against — that is usually enough for us to resolve it quickly. Our privacy policy explains what we do with anything you send us.
