Editorial and corrections policy

A useful financial calculator must show where its inputs came from, what its formula leaves out, and when it was last checked.

Who publishes the site

1099 Money Desk is published by Alonso Verdeja, Publisher and product editor. No CPA, enrolled-agent, legal, investment-adviser, or financial-planner credential is claimed. The site provides educational arithmetic, not individualized advice.

Source standard

Federal tax amounts are taken from primary IRS publications, revenue procedures, notices, and Social Security Administration releases. State schedules are checked against state forms, statutes, agency notices, and a dated nationwide compilation that documents those underlying sources. Commercial prices such as card processing fees are checked against the provider’s own US pricing page. A blog or competing calculator may help identify an issue, but it is not used as the final source.

Testing and review

Each calculator has fixed examples that test its arithmetic, boundary conditions, and declared outputs. Rates for tax year 2026 were last reviewed on 2026-07-25. Tests confirm that the code follows the documented method; they cannot make a simplified method suitable for every taxpayer.

Corrections

A material error is corrected as soon as it is verified against a controlling source. The affected page receives a new verification date and its tests are updated. A public corrections log will appear here when the first post-publication correction is made. A domain-based reporting address will be activated with the permanent domain before advertising or affiliate links go live.

Annual maintenance

HSA limits are checked in spring; Social Security and retirement limits in fall; tax brackets and deductions when the IRS publishes inflation adjustments; and mileage rates at year end and again if the IRS announces a midyear change.
