References for the people who actually do the filing

Surplus lines compliance is spread across fifty sets of rules, four platform families and a calendar nobody owns. These are the references we keep for our own filing team, published because they are more useful shared than hoarded. Every fact links to the official source it came from.

Surplus Lines Filing Deadline Calendar, 2026–2027

Every filing and tax deadline for the fifteen stamping-office states, each one linked to the stamping office, state department or statute it was read from — plus a calendar file you can import so the dates land in your own reminders.

More is coming: the same treatment for the states that file with the insurance department directly, and a plain-language guide to which platform each state actually uses. If there is something you keep having to look up, tell us and we will put it on the list.
