A scheduled adjustment has passed since this rate took effect

This fee escalates annually. The rate on file is effective 1 Jan 2025, 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 Jul 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.

Before any discounts. Some fees offer credits, waivers or phase-ins. They’re listed above but not subtracted, because whether you qualify depends on your project.

Check the date. Fees change. This page shows what was in force on the date at the top, with a link to the document that set it, so you can confirm the current amount yourself. How all of this is put together.
