How we verify deadlines

One wrong date costs a reader a penalty, so the standard is deliberately strict.

The rule

A date is published only when it appears on the county's own website — the treasurer, the tax collector, or the state statute the county collects under. Newspapers, tax-lien companies and national summaries are not accepted as sources.

What every page records

• The exact source URL used, linked on the page.
• The date we checked it — the "verified" line under the deadline table.
• The county's own payment portal, so you can confirm in one click.

When a date cannot be confirmed

The county is left out rather than filled in with a guess. Coverage grows a few counties at a time as each one is checked by hand.

Corrections

If a county changes a date or you find an error, send it in with the page URL and we will re-check it against the official source and correct the page.

StacyApproved is an independent reference and is not a government agency. Deadlines change and exceptions apply — always confirm with your county treasurer using the official link on this page. Nothing here is tax, legal or financial advice.
