1.4 Economic sector

The main activity of each company is obtained from the annual VAT return, from the information on the headings of the annual economic activities tax, and from the main activity assigned in the Census of Large Companies. Based on this information, starting in 2009, the Economic and Tax Results statistics on VAT present a new sectoral classification harmonized with the new National Classification of Economic Activities (CNAE 2009):

01 Agriculture, livestock, forestry and fishing
02 Extractive industry, energy and water
03 Industry
04 Construction and real estate activities
05 Trade, repairs and transportation
06 Information and communications
07 Financial and insurance entities
08 Business Services
09 Social services
10 Other personal and leisure services
11 Unrated

In some statistical tables this classification by economic sector is presented with the following grouping:

Agriculture, livestock, forestry and fishing
Industry: formed by sectors 02 and 03
Construction and real estate activities
Trade and communications: formed by sectors 05 and 06
Financial activities and business services: formed by sectors 07 and 08
Social services
Other and unclassified services: formed by sectors 10 and 11

For the 2024 financial year, a broader sectoral classification is being added, breaking down the 11 classification into 32 sectors (NACE32). See Annex I. Sectoral classification.
