French Budget Minister Gérald Darmanin unveiled on Sunday a plan to extend the use of social media in the fight against tax evasion as early as 2019, a policy that is already used successfully in the UK. The goal of the experimental plan will be to identify discrepancies between a citizen's declared revenue and the lifestyle they share on social media.
“(The fiscal administration) will be able to see that if you have numerous pictures of yourself with a luxury car while you don’t have the means to own one, then maybe your cousin or your girlfriend has lent it to you, or maybe not,” Darmanin told French business TV show Capital.
Tax evasion cost the French government an estimated €80 billion to €100 billion in 2017, up from €60 to 80 billion in 2013, according to Solidaires Finances Publiques, the largest union representing France’s tax authorities.
The measure is part of a new French law passed in October that grants authorities greater freedom to use online data to crackdown on fiscal fraud. The legislation also requires “sharing economy” platforms, such as Airbnb or Uber, to provide tax authorities with their users’ earnings, and includes a provision that allows for information to be more easily shared between administrative services for data mining purposes.
Similar initiatives in countries such as the United Kingdom have been met with success. In 2008, Her Majesty’s Revenue and Customs (HMRC) launched a computer system known as Connect, which enables tax authorities to collect, analyse and store massive amounts of personal and commercial data that can be cross-referenced with taxpayers’ declared income to identify cases of potential fraud. Since its introduction, Connect has generated £3 billion in additional tax revenue.
Satellite imagery can also be used.
Social media, such as Facebook, Twitter, Instagram and LinkedIn have also provided HMRC with a trove of information. The tax authority has even been known to use satellite imagery captured by Google Earth to flag expensive building renovations
The system, however, has its flaws: because authorities are restricted to viewing public social media profiles, nothing can be watched if users make their accounts private. Also at stake is the issue of how accurately can people's life be reflected by posts on social media.
“In reality, there’s burden of proof. When it comes to the Internet, (French) jurisprudence is pretty restrictive,” Antoine Colonna D’Istria, an associate at the Paris offices of the global law firm Norton Rose Fulbright, explained.
“Judges are more reticent to admit evidence that comes directly from the Internet. (Social media) users can fantasize, and a photo can be re-touched using software.”
Still, Darmanin hopes that trawling social media accounts will help crack down on growing fiscal fraud in France.
