  • Reliability

    We seek feedback and advice about the methods we use to estimate the gap from our external and internal subject matter experts. Based on the advice and assessment, the reliability for this estimate is low (with a score of 15).

    This is low because there are some ongoing issues with the data inputs to the model. The data is subject to revision and has historically impacted the most recent years of published gap estimates. There is no official source for such estimates as highlighted by the final report of the Black Economy Taskforce.

    We will continue to refine our work on the PAYG withholding gap in future releases.
