Tax fraud: Bercy demanded €17.1 billion 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 rug?” Sure, committing tax fraud is wrong. But let’s be honest – some people have practically turned it into a national pastime. Except Bercy has decided to win at that game. And in 2025, the tax authorities have just smashed a record that makes your head spin: €17.1 billion claimed 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 exploded. In 2025, tax inspectors no longer search by guesswork – they target. AI continuously analyses abnormal bank flows, discrepancies in declarations between individuals and businesses, and even suspicious behaviour on short-term rental platforms. The result? €17.1 billion in tax fraud has been notified to taxpayers who got a little 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 concern dodgy big bosses. The self-employed tradesperson who inflates their expenses, the influencer who “forgets” to declare brand partnerships, the Airbnb host who pockets rent without telling the taxman… Everyone gets caught. And with AI, nobody 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 in the streets of trendy neighbourhoods. We’re seeing a proliferation of washed-out streetwear T-shirts bearing ironic slogans like “Legalize tax fraud” or “Committing tax fraud? A 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 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 legalise tax fraud into an absurd and provocative slogan. Behind the joke lies real tax fatigue. But beware: wearing an ironic T-shirt won’t protect you from an audit. The algorithm doesn’t do sarcasm.
Should you fear the new-generation taxman?
The honest taxpayer has nothing to fear – except maybe a bit more transparency. What’s changed is that the everyday little dodges – the famous “it’s just to make ends meet” – have become manna from heaven for Bercy’s machines. The authorities are no longer messing around. And the €17.1 billion in 2025 is only 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 a guy on the Luas with a mocking 3XL print, smile. But keep all your receipts up to date. Because Bercy’s eye never blinks.
