What this measures

Income tax receipts in cash terms: the outturn as the OBR last knew it, with every official forecast for the same year.

What this doesn’t measure

Income tax paid by any group, or the effect of any one policy.

Important caveat

Each forecast vintage uses the definitions and classifications in force when it was made, so the outturn the OBR shows beside it may differ from today's ONS series after later classification changes and revisions. The outturn row is the figure as the OBR knew it at its most recent forecast, not the latest ONS estimate. Forecasts before June 2010 were produced by HM Treasury, not the OBR. Fiscal series are financial years; economy series are calendar years. A forecast is a statement of uncertainty made at the time and is stored as an estimate; a miss is not evidence of misconduct.

Revision history

No period of this series has been revised since it was first ingested here. Revisions are recorded automatically when a later release publishes a different figure for the same period.
