Trust & accountability
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. The state calculator is a bounded planning library: a dated nationwide compilation is used to discover and compare rate schedules, while the linked USAGov and Federation of Tax Administrators directories lead users to the state authority whose current forms and instructions control. The site does not claim that the library replaces a state form or resolves a user’s jurisdiction. 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 treated as controlling authority.
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.
Jurisdiction and model boundaries
Federal tax tools are designed for US federal planning. The state tool covers rate schedules for the 50 states and Washington, D.C. only. The site does not determine residency, part-year or nonresident filing, multistate allocation, local tax, credits, US-territory tax, treaty treatment, foreign income exclusions or credits, or tax rules outside the United States. Those questions require the current official instructions and, where appropriate, a qualified professional.
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. The site does not currently provide a contact form or reporting mailbox, so it does not claim to accept visitor-submitted corrections at this time.
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.
