Presentation

Based on the observation that taxation and social security contributions were weighing on industrial competitiveness – thereby contributing to a process of deindustrialisation that was proceeding more rapidly in France than in several other European countries – a number of public policies aimed at reducing the tax burden have been implemented since 2013.

This study focuses on the following recent reforms: the conversion of the business tax into the CVAE; reductions in the CFE, the CVAE and the tax on production premises; and reductions in social security contributions.

Measuring the burden of corporate taxation requires taking into account not only its direct component (the compulsory levies to which firms are subject), but also its indirect component, i.e. the increases in the prices of inputs that these compulsory levies generate upstream in the production process, as well as the compulsory levies that can be passed on downstream along the production chain via higher prices. As the industrial sector is characterised by a complex network of input-output relationships, taking these indirect tax effects into account is particularly important for understanding the burden of compulsory levies. This study therefore also aims to measure the second-round effects that arise from improvements or deteriorations in the profitability of the sectors that supply industrial firms. This involves modelling the extent to which prices are distorted by the French tax system along the value chain.

Key Results

  • Social security contributions remain high overall, but the CICE tax credit and the shift towards reduced contribution rates have reduced labour costs, particularly for wages below 2.5–3.5 times the minimum wage, with varying effects across different industrial sectors.
  • Within the industrial sector, firms with significant capital expenditure (machinery, premises) benefit more from reductions in production taxes, whilst firms with a wage bill close to the minimum wage benefit more from reductions in social security contributions.
  • For the reforms as a whole, the amplification effects via the production network are significant.
  • However, the relative weight of direct and indirect effects varies depending on the reforms. The industrial sector benefits more significantly from the TP reform, both before and after taking network effects into account. Industry benefits less from the CICE, but has a higher ratio of total effect (direct + indirect) to direct effect than non-industrial sectors. Thus, although the CICE has directly benefited non-industrial sectors more, the structure of the production network means that the indirect amplification is greater in industry than in other sectors. Conversely, the direct gain is relatively high but the amplification is limited in the case of the reduction in the CET.

NB: The results presented are purely descriptive and should therefore not be interpreted in a causal manner.

Method and Data

The compilation of the data set at the detailed sector level is based on the matching of the following three databases using the SIREN identifier for all years between 2005 and 2022.

Establishment characteristics. Data on establishments are drawn from the ‘Base Tous Salariés’ (BTS) database, formerly known as the DADS (Annual Declaration of Social Data).

Company tax data. Data on industrial and commercial profits under the standard regime (BIC-RN) are compiled from tax returns submitted by firms.

Scope of tax groups. Tax groups are determined using PERIM data from the DGFiP, which provides the SIREN numbers for the tax group as well as for all the firms comprising it. This data enables us to define the sector of activity at tax group level.
