2026 fiscal calendar
Know the tax date before it becomes a penalty date.
Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The verified record below separates published figures from dates that require confirmation with St. Johns County Property Appraiser.
Effective rate
Florida property-tax bills combine millage rates set by multiple taxing authorities, so there is no single countywide effective percentage for all parcels.
Statement mailing
October 31, 2026; the official St. Johns tax calendar states tax bills are mailed October 31.
Payment deadline
March 31, 2027; 2026 real-property taxes must be paid by March 31, 2027 to avoid becoming delinquent April 1, 2027.
Valuation protest
25 days after the 2026 TRIM notice; St. Johns states the 2026 TRIM notices will be mailed August 17, 2026, and the deadline appears on the notice.
Critical payment warning
Do not assume a grace period.
The verified county record identifies the payment timing above but does not establish a universal penalty schedule for this page. Late charges, interest, collection costs, tax-sale procedures, and lien or foreclosure timelines can depend on state law and the local collector’s process. If the deadline is close or a balance is delinquent, contact the tax collector directly and request the current payoff amount in writing.
Treat the published payment deadline as a hard operational date and retain your receipt or confirmation number.
Read the calendar in order
From assessment to collection
1. Valuation and notice
Review the assessment notice as soon as it arrives. The protest window may run from the notice date rather than from the payment due date.
2. Statement and account review
Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.
3. Payment confirmation
Use the official collector channel, then save the receipt, transaction reference, and date posted. A bank submission is not always the same as a county posting date.
