Tax fraud: Bercy clawed back €17.1bn in 2025 – and AI changed everything
We've all had that guilty thought while filling out our tax return: 'What if I just sweep a little something under the carpet?' Sure, committing tax fraud is wrong. But let's be honest, some people have turned it into a national pastime. Only now, Bercy has decided to win at that game. And in 2025, the tax authorities have just posted a dizzying record: €17.1 billion claimed back from fraudsters. A feat made possible by an unstoppable weapon: artificial intelligence.
AI on the trail of fraudsters: how Bercy doubled down
Gone are the days of random spot checks. Ever since the state got its hands on predictive algorithms, the success rate of tax investigations has soared. In 2025, tax officers no longer search by guesswork – they target. AI continuously analyses unusual bank flows, discrepancies between individual and business declarations, and even suspicious behaviour on short-term rental platforms. The result? €17.1 billion in tax fraud has been flagged to taxpayers who got a bit too creative. That's a jump of nearly 30% compared with 2024. And the Economy Minister didn't hide his satisfaction – nor his promise to do even more next year.
- €17.1bn: the total amount claimed in 2025, an all-time record.
- +32% more successful audits thanks to AI since 2023.
- Nearly 60,000 tax adjustment notices sent out last year, a 25% increase in just 12 months.
What often goes unsaid is that these figures don't just concern shady CEOs. The self-employed trader inflating his expenses, the influencer who 'forgets' to declare brand deals, the Airbnb host pocketing rent without telling the taxman… Everyone gets caught. And with AI, no one can rely on luck to slip through the net anymore.
'Legalise tax fraud'? The provocative T-shirt causing a buzz
In this context, a strange trend has emerged on social media – and in the streets of trendy neighbourhoods. Vintage streetwear T-shirts are popping up, sporting ironic slogans like 'Legalize tax fraud' or 'Committing tax fraud? Funny hobby.' Yes, you read that right. These short-sleeved tops for men and women, often with a 3XL retro print, play the irony card to the hilt. The retro T-shirt look embraces very French dark humour: 'Since it's become impossible to cheat, we might as well laugh about it.'
Some Parisian streetwear creators have mischievously seized on the issue, turning legalising tax fraud into an absurd, provocative slogan. Beneath the joke lies genuine tax fatigue. But be warned: wearing an ironic T-shirt won't protect you from an audit. Algorithms don't do irony.
Should you be afraid of the new-generation taxman?
Honest taxpayers have nothing to fear, except maybe a bit more transparency. What's changed is that everyday little dodges – the classic 'it helps make ends meet' – have become manna from heaven for Bercy's machines. The authorities are no longer messing around. And the €17.1bn in 2025 is only the beginning. Because every euro clawed back is a euro that can fund hospitals, schools or the green transition. Hard to argue with that, even when you're wearing a 'Legalise tax fraud' T-shirt just to be provocative.
So if you see someone on the Tube with a mocking 3XL print, smile. But make sure all your receipts are up to date. Because Bercy's eye never blinks.
