Tax fraud: Bercy claims €17.1 billion in 2025 – and AI has 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 rug?" Sure, committing tax fraud is wrong. But let's be honest, some people have almost turned it into a national sport. Except Bercy has decided to win at that game. And in 2025, the tax office has just smashed a record that makes your head spin: €17.1 billion claimed from fraudsters. A feat made possible by an unbeatable weapon: artificial intelligence.
AI on the trail of fraudsters: how Bercy has upped the ante
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 skyrocketed. In 2025, tax agents no longer search by guesswork – they target. AI continuously analyses abnormal bank transactions, discrepancies between individual and business filings, and even suspicious behaviour on short-term rental platforms. The result? €17.1 billion in tax fraud has been notified to taxpayers who were a bit too creative. That's a jump of nearly 30% compared to 2024. And the Economy Minister didn't hide his satisfaction – nor his promise to do even more next year.
- €17.1 billion: the total amount claimed in 2025, an absolute record.
- +32% more successful audits thanks to AI since 2023.
- Nearly 60,000 tax adjustment notices sent last year, a 25% increase in just 12 months.
What often goes unsaid is that these figures don't just target crooked CEOs. The tradesperson inflating their expenses, the influencer "forgetting" to declare brand deals, the Airbnb host pocketing rental income 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 making waves
In this context, a strange trend has emerged on social media – and on the streets of trendy neighbourhoods. Faded streetwear T-shirts are popping up, featuring ironic slogans like "Legalise tax fraud" or "Committing tax fraud? Funny hobby." Yes, you read that right. These short-sleeve tops for men and women, often in a vintage-style 3XL print, play the most deadpan ironic card. The retro T-shirt look embraces a very French dark humour: "Since cheating has become impossible, we might as well laugh about it."
Some Parisian streetwear creators have mischievously seized on the issue, turning legalising tax fraud into an absurd and provocative slogan. Behind the joke lies genuine tax fatigue. But beware: wearing an ironic T-shirt won't protect you from an audit. Algorithms don't do sarcasm.
Should you be afraid of the new-generation tax office?
Honest taxpayers have nothing to fear, except maybe a bit more transparency. What's changing is that the little everyday dodges – the classic "just to make ends meet" – have become easy pickings for Bercy's machines. The tax office is no longer messing around. And the €17.1 billion in 2025 is just the beginning. Because every euro recovered 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 metro with a mocking 3XL print, smile. But make sure all your receipts are up to date. Because the eye of Bercy never blinks.
