Précision et fiabilité
Monthly tax returns cover about 97% of the returns.
Sampling error and A1. Sampling errors – indicators for U
Non-sampling error and A4. Unit non-response - rate for U and A5. Item non-response - rate for U
Late responses may lead to small revisions even though there is no particular bias.
There are no actions to speed up or increase the response rate as this is a near exhaustive administrative source.
The indices are calculated on the basis of all monthly VAT returns of enterprises.
Legal units declaring annually or quarterly are therefore excluded, but these represent a marginal share in most economic sectors.
Businesses that declare VAT on a monthly basis are those that are subject to the normal real tax regime.
The coverage rate (share of monthly declarations/total declarations) is over 97%.
The indices cover the whole of France, including the overseas departments with the exception of French Guiana and Mayotte, which are not subject to VAT.
The measurement error is small: this would be due to inaccurate reporting not identified in the data clearance process.
Non response error
The non-response error is negligible.
The process is robust and uses cross-validations methods.
