Benefits deadlines to track for an aging parent, verified against the source
A family helping an aging parent may have dates spread across Medicare and state benefit systems. This page organizes only the dates and annual windows already verified in the NoticeOfChange reference registries. They are dates to be aware of, not advice to file, enroll, appeal, or change coverage.
Senior property-tax exemption filing deadlines
The registry covers statewide homestead-related filing rules in eight states. Some rules are specific to age or another eligibility category, while others are broader homestead rules. The cited law controls, and the rows do not add states or local dates that are absent from the verified dataset.
Florida
File by March 1
Florida homestead (and related) exemption applications are filed with the county property appraiser on or before March 1. Missing March 1 waives the exemption for that year.

Annual IRMAA determination timing
Annual determination using tax information from two years earlier

No. These are dates and recurring windows to be aware of. NoticeOfChange explains and organizes source-verified timing, but does not advise a family to file, enroll, appeal, or change coverage.
Why does every state row show a verification date?
The verification date shows when the cited primary source was last checked for the rule displayed in that row.

Medicare.gov lists the fall Open Enrollment window as October 15 through December 7 each year.
