How StateDue verifies deadlines

Annual report and franchise facts were checked automatically against the text of official state Secretary of State / revenue / legislature pages fetched on last_verified. 'confirmed' = every key token (due date and fee) was found on those pages; anything else is flagged for human review. Income and sales tax entries are general patterns and are marked unverified.

Coverage

43 of 51 jurisdictions have annual-report facts confirmed on official pages as of Oct 21, 2026. Flagged for review: Idaho, Illinois, Missouri, New Mexico, New York, North Dakota, Ohio, South Carolina.

Federal dates follow the rules in IRS Publication 509 (2026), adjusted for weekends and federal holidays. IRS disaster postponements are re-checked automatically against irs.gov.
