3.1 Information on TE coverage - To what extent does the TE report cover all Tax Expenditures available at the national level?

3.2 Tax benchmark explanation - To what extent is the tax benchmark used to assess TEs specified in the report?

This indicator assesses whether the TE report defines the benchmark tax system and at what level (per TE provision, by type of tax, or only in general terms).
