Tax Gap Estimation - Why? and How?

Following on from a successful event on tax gaps run by IOTA in June 2014, there was very strong feedback that a further event going into more detail on how to estimate tax gaps was needed. Also, since then, tax gap estimation has been getting more and more attention with Tax Administrations coming under increased pressure to either provide estimates or strong reasons why they choose not to. This event would include presentations on the reasons behind estimating tax gaps, their uses and how they are estimated. It would allow IOTA members to talk through the many issues and facets of this difficult subject area
