revenue estimation

The Kyscope is a computer model that allows users to play around with changes to domestic and overseas income tax treatment of chosen investments. Through its linked set of Microsoft® Excel spreadsheets, users can:

  • see the impact of investment income tax changes on cash flow, tax revenue and rates of return
  • trace through the hard numbers produced for assets, entities and entity owners to get an integrated view of tax arrangements.
  • The Kyscope is designed to facilitate the development, implementation and evaluation of business income tax policy measures or to scaffold the exploration of theoretical considerations.

    MyProject software download
    MyProject is a computer package (49.7Mb download) that helps the user assess the financial viability of investment projects after the imposition of a wide range of income, capital gains taxes, royalties and resource rent taxes. Written in Microsoft® Visual Basic.Net®, MyProject offers an easy-to-use format for analysis of actual or hypothetical data with flexibility over the number of years of analysis, number of capital investments per year and number of products from each project. MyProject analyses the cash flow of projects regardless of the investor, in contrast to the Kyscope which can analyse the position of people investing via a chain of local or international entities and the position of these entities themselves.

    MyProject offers an easy-to-use, flexible format and, while being a stand-alone package, also complements the Kyscope package by:

    In contrast to the Kyscope, MyProject undertakes analysis purely on a local project basis, regardless of the type of taxpayer investing in the project. The Kyscope can analyse the position of people investing via local or international entities (like companies and trusts) and the position of these entities which themselves might be investing via other local or international entities.

    If you wish to ask questions, provide comment or discuss the question of workshops/presentations on concepts and design issues relating to the taxation of income or economic rent from investments drawing on the Kyscope and MyProject .
