Global Tax Expenditures Transparency Index (GTETI)
- Concept Note -
Governments use tax expenditures (TEs) - also called tax breaks, tax reliefs or tax subsidies - to
pursue a variety of policy goals. TEs are deviations from the benchmark or standard tax system
that provide preferential tax treatment to individuals or businesses. They can trigger substan-
tial tax revenue losses. According to the Global Tax Expenditures Database (GTED), the global
average of revenue forgone due to TEs among the 106 countries that publish such data is 4.2
percent of GDP and 22.9 percent of tax revenue over the 1990-2021 period. In some countries,
such as Czechia, Finland, Jordan, the Netherlands and Russia, revenue forgone from TEs can
amount to more than 9 percent of GDP.
Given the magnitude of TEs, the estimation and reporting of their fiscal cost should be a prior-
ity for governments worldwide. Such estimates are a necessary input to evaluate the effective-
ness and efficiency of TE provisions and, ultimately, to decide which provisions to keep, modify
or remove. However, the quality of TE reporting is often poor and important data is frequently
missing.
Few studies compare TE reporting across countries.
For instance, Kassim and Mansour (2018) evaluate The GTETI at a glance…
the TE reports of 21 developing and transition econ- 100+ reporting countries
omies, using a matrix of dimensions that character- Five dimensions, 25 indicators
ize good practices in TE reporting. Redonda and Freely accessible online
Neubig (2018) apply a similar approach to the 43 Regularly updated
G20 and OECD economies. Based on GTED data, Qualitative and quantitative
von Haldenwang et al. (2021) assess the large varia- assessments

external consultants
The Global Tax Expenditures Transparency Index Prior notification of jurisdic-
(GTETI) is the first comparative assessment of TE re- tions and conflict resolution
porting that covers countries worldwide. Building mechanism
on the data collection and classifications developed
to construct the GTED, the GTETI provides a sys-
tematic framework to rank countries according to the quality of their reporting. Countries are
not compared according to the amount of revenue forgone they report, but rather assessed
on five dimensions: (1) public availability of TE reports, (2) an institutional framework that en-
sures transparency and accountability, (3) general information on the scope of reporting and
methodology used, (4) detailed information on individual TEs, and (5) information on revenue
forgone and evaluations.
The GTETI aims at increasing transparency and accountability in the TE field, promoting public
debate and encouraging governments to improve their TE reporting as a first necessary
(though certainly not sufficient) step towards comprehensive evidence-based TE reform.

Dear Sir or Madam,
My name is Sofia Berg and I work as a Research Analyst for the Council on Economic Policies (CEP).
CEP, together with the German Institute of Development and Sustainability (IDOS) are launching the
Global Tax Expenditures Transparency Index (GTETI). The GTETI aims to increase tax expenditure
transparency and accountability by providing a systematic framework to rank countries according to the
regularity, quality, and scope of their tax expenditure reports – FYI, you find the GTETI Concept Note
attached.
I am reaching out to you because the last stage of the GTETI assessment requires to share the GTETI
Scoring Sheet with the governments of the assessed countries to give them the possibility to comment
or let us know if they find something incorrect.
You find attached the GTETI Scoring Sheet for Estonia. We would grateful if you could review it and let
us know if there is something you would like to discuss or change by Friday October 6, latest. If you
agree with the assessment and think that nothing needs to be changed, we would appreciate if you
could confirm that through a brief response to this email. If you need support with the translation of the
scoring sheet, please let us know. We would be happy to help. Alternatively, publicly available and free
of charge translation tools such as Deepl and Google Translate be useful.
The GTETI will be officially launched on October 9 (2.00-5.30 pm CEST) through a hybrid event, and the
GTETI team would be delighted to have you joining us – please feel free to share the invite with your
colleagues and networks if you think this could be of interest. You find more details about the event
here, and the registration link to the event here.
I remain at your disposal should you have questions or comments.
Thank you very much for your time.
Best regards,
Sofia Berg
