The evidence behind every estimate.

Trace a result to the official rule. This register records what was checked, where it came from, and which version is in use.

10 of 18 sources match; 8 sources need verification

Only estimates that depend on the sources below are paused. Open a source for its last successful check and current status.

What “verified” means here

Source values and effective dates have been checked against official material, and the engine has independent reference tests. This is implementation verification, not a claim of professional tax review or government endorsement. Current-year law can change.

Source monitoring compares the registered evidence with newly retrieved documents. A changed or unavailable required source pauses fresh estimates. A verification check expires after 14 days even if a scheduled job does not run.
