    Course Description

    The Tax Administration Diagnostic Assessment Tool (TADAT) provides a 360-degree diagnostic of the performance of a tax administration using nine performance areas and 28 indicators. TADAT assessments focus on the administration of the following core taxes:

    • Goods and Services Tax (GST) / Value Added Tax (VAT)
    • Corporate Income Tax (CIT)
    • Personal Income Tax (PIT)
    • Pay As You Earn Amounts (PAYE)
    • Domestic Excise Taxes

    By assessing outcomes in relation to the administration of these core taxes, a picture can be developed of the relative strengths and weaknesses of a country's tax administration system.
    The performance assessment is first used at the national or sub-national system-wide level, thereafter, particularly in a large country with a federal structure such as India, regional variations can be identified by conducting guided assessments at the regional level to identify specific weaknesses in different regions.

    The training workshop is presented by the TADAT Secretariat and consists of the following presentations:
    (i) the design principle and purpose of TADAT;
    (ii) the scoring methodology for each of the performance areas and indicators based on the TADAT Field Guide;
    (iii) the pre-assessment, assessment, and post-assessment phases of a TADAT diagnostic; and
    (iv) how to prepare a quality Performance Assessment Report (PAR). 

    In addition, the workshop has discussion sessions where practice exercises and case studies mimicking real life situations are discussed.

    Finally, a one-hour TADAT online exam is conducted. Those who pass the exam (75 percent correct response) will receive a TADAT certificate. Following successful completion of the course, participants who have some international experience, may be invited to participate in conducting TADAT assessment in any other country. Participants will also be equipped to participate in an assessment of their own administration during the pre-assessment phase.
