Turnover indices are calculated based on tax data, i.e. the CA3 declaration, the form which businesses must fill in each month or each quarter for the payment of VAT.
They include the full turnover of declaring businesses, all activities included, classified according to the business's principal activity.
For exports outside the European Union and products supplied within the Community, the Turnover Indices are established according to the amount of turnover declared by enterprises. They are used to monitor the turnover, given in euros, with foreign countries.

Monthly

The Sales Indices in Industry and Construction are created from a tax source - the CA3 form, which enterprises must complete for the payment of Value-Added Tax (VAT).

In certain sectors in which the turnover of enterprises not subject to the "actual normal" tax system is substantial, the information source is supplemented by a monthly postal survey administered to a rolling selection of enterprises not subject to the "actual normal" tax system.

The indices are thus representative of the trend for turnover in all sectors.

This index is calculated for "Whole France" (except French Guyana and Mayotte which are not liable to VAT).
