Editorial policy

How we choose sources, check facts, verify employers and fix mistakes.

Last updated

Sources we use

  1. The law, the Federal Register and the Internal Revenue Bulletin.
  2. IRS and Treasury pages, forms, instructions, notices and FAQs.
  3. For employers: the company's own announcement, or a named news report that quotes the company.

News articles help us find updates, but a number only goes on the site once we've traced it to a primary source.

Fact checks

Every figure is checked by hand against its source before it's published, and again whenever the IRS updates the related form or guidance. Each page shows the date its figures were last checked.

Employer database

A company is added only with a public source. Each entry shows who reported it and when we last verified it. If a company changes or drops its plan, we update the entry and keep a note of the change.

Corrections

If you spot an error, tell us. We fix confirmed errors within 2 working days and record them in the updates log.

Ads and independence

Advertisers don't see or shape our content. Ads sit below results, never inside a calculator.
