The Paradox Box™

An expert software system to analyze and optimize large sets of tax data.

The most affordable and fastest software to implement on the market

Mobilising revenues is more and more a matter of leveraging data. Robust and trustworthy data allows revenue administrations to adopt modern techniques such as risk-based audit or performance management using dashboards and KPIs. As revenue administrations strive to label themselves ‘data driven’, the need for increased governance and data management practices becomes increasingly important. Indeed, information becomes an asset and has to be trusted by users.

The Paradox Box™ has an open architecture designed to interface and integrate data from multiple sources, and then use this data for the purposes of the tax departments. The system currently integrates data from Customs, Treasury and Revenue Administrations. The data from multiple data sources can then be cross-referenced, mixed and mashed to display strategic information cutting across all the data.

Features include:

  • Advanced algorithms to identify problematic data, develop risk criteria, etc.
  • Workflow and case management engine to computerise and structure processes.
  • Dashboard to monitor the performance, be it progress in data cleansing or progress of the execution of the audit plan.

Technical Profile of The Paradox Box™


  • The Paradox Box™ is being currently operated in English, French and Spanish, and can easily be translated into other languages

Locally or on the cloud

  • Can be installed locally on a server as part of the organisation’s IT infrastructure, but also accessed from the internet cloud (directly from the internet with no local installation). Cloud deployments are strongly encouraged as they ensure lower costs, much higher reliability, accessibility, security, and unlimited processing power and storage.

Responsive design

  • Designed so that it can be comfortably accessed and operated on mobile devices such as smartphones or tablets. .


  • Any type of indicator, for any type of data, can be configured. There is no prescription of format nor industry sector.


  • Can load data from any system running on any custom system or database (e.g. Oracle, SQL Server), any REST-like API, and even from file sources in various formats, such as CSVs, etc.

    Support Data Exports
    All data can be exported from the system and be readable by MS Excel or any other kind of spreadsheet or database.

Users management

Applications of The Paradox Box™ Open Architecture

Timor-Leste decided to conduct a nation-wide re-registration of all of its taxpayers because it began to be suspected that too many taxpayers had multiple TINs or had incomplete registration records. There had been more and more loss of national revenue, at times due to criminal fiscal evasion. The Paradox Box™ was used to:

The Paradox Box™ platform has been used to:

  • Identify duplicate taxpayers by de-duplicating the Tax database.
  • Cross-reference the Tax database with that of Customs to identify taxpayers under different identities in each system.
  • Cross-reference the Tax database with that of the Treasury’s vendors (taxpayers having a government contract) to associate the TINs to Vendors’ records.
  • Computerize the workflow between the front desk, the specialists, the data entry, and the managers
  • Report to management on progress.

Results Achieved:

  • 40,000 TINs analyzed by The Paradox Box™.
  • 16,000 TIN duplicates identified and cleansed.
  • 400 TINs were found active in ASYCUDA while inactive in the tax database.
  • 34,000 vendors in the Treasury’s database cross-referenced with the tax database’s TINs. TINs were associated to the corresponding vendors in the Treasury’s system to avoid payment if tax obligations were not encountered.
  • 8,000 taxpayers re-registered anew.
  • New registration centre with 25 registration officers being using The Paradox Box™.
  • Interface of The Paradox Box™ with the One-Stop-Shop’s system to prevent new duplicates from appearing.
