Fertilizer filing deadlines, month by month

Every tonnage report date, licence renewal and registration expiry we could pin to a day, across the 50 documented states. 136 dated deadlines in total; January is the heaviest month. Built from the same open dataset as the state guides, rules last reviewed 2026-09-19.

A date appears here only when the official source names a day. States whose deadline is written as “within 30 days of the period end” or otherwise not fixed are listed below the calendar, not guessed into it. Where a statute and an agency form disagree on the day, we show the earlier.

Deadlines without a fixed day (9 states)

These states publish the obligation but not a calendar day we could rely on. The guide for each explains what the source actually says.

No tonnage report at all (3 states)

Alaska, Hawaii, Wyoming. Where these states register products, the expiry date is in the calendar above.

How to use this page

Filing obligations start the day you first distribute in a state, and none of these agencies send reminders. Use the planner to select only the states you sell in and export the dates to Outlook or Google Calendar with a 14-day alarm. Then open each state guide before you file: the guide carries the fee, the filing route and the official source for every line.
