A scheduled adjustment has passed since this rate took effect

This fee escalates annually. The rate on file is effective 1 Jan 2026, and at least one adjustment has fallen due since. The current amount is probably different, and for an indexed fee almost certainly higher. The next change after that is expected 1 Mar 2027.

The figure is published as held rather than projected forward, because a number computed from an index is not a number quoted from an adopted schedule. It is flagged so you can check the agency's current schedule before relying on it.
