Editorial policy

Penny Rounding Laws covers rules that affect people's money, benefits and health coverage. Getting them right matters more than being first, so every page follows the same process.

Primary sources first

We build each page from the official record: the law itself, federal regulations and the Federal Register, guidance and letters from the responsible federal agency, enacted state bills, and official state agency notices and manuals. Each page lists the sources it relies on at the bottom, with links, so you can check them yourself.

We use news reports only to find leads or, when no official record exists yet, to report what an agency or company has said publicly. When we do, the page says the information is reported and not confirmed by an official source.

What we will not publish

• Numbers, dates, deadlines, phone numbers or rules that we could not trace to a named source.
• Guesses about how an agency will decide an individual case.
• Paid placements. Advertisers have no say over what we write or how our calculators work.

How the calculators are checked

Each calculator applies the published rule step by step, and its logic is tested against worked examples taken from the official rules before every update. Money math is done in whole cents to avoid rounding errors. The calculators run in your browser, and nothing you type is sent to us.

How we keep pages current

We review every topic at least once a month for new laws, agency rules, waivers and court decisions, and sooner when a major change happens. Each page shows the date it was last updated, and our updates log lists every significant change.

How we write

We write in plain language for the people the rules affect. We use software tools, including AI, to help research and draft. Every fact is checked against the source cited on the page before it is published.

Corrections

If you find an error or a rule that has changed, contact us with the page address and, if you can, a link to the official source. We check every report against the official record and fix confirmed errors promptly, updating the page date.
