year

Four-digit year or "latest".

Value

Details

Thin wrapper pointing users to readoecd:: for full OECD API access; returns a minimal tax-to-GDP slice here for convenience.

Data vintage. The bundled headline ratios are hardcoded and currently run to 2023 (Australia reports to the OECD a year behind most members). They are not refreshed automatically. For anything load-bearing use readoecd:: against the live OECD Data Explorer rather than this convenience slice.
