How this code is used
NOGA code 43.5 is used by the Swiss federal authorities to classify companies by their main economic activity, notably:
- Federal Statistical Office (FSO): business and establishment register (BER), censuses and structural statistics.
- OASI compensation funds: classification of the employer's activity at registration.
- Federal Tax Administration (FTA): VAT profiling, net tax debt rates and sector statistics.
- Commercial register: "activities" field when registering a new legal entity.
- SUVA and accident-insurance funds: pricing of accident-insurance contributions by risk class.
- SECO and labour-market statistics: sector analyses and targeted support measures.
