The company should have withheld correctly from the start
A quiet but consequential legal principle is gaining attention: when an employer fails to withhold the correct amount of tax from a worker's paycheck, the resulting debt belongs to the company, not the employee. Labor lawyer Juanma Lorente and tax specialist Julia Coronel are bringing this overlooked provision into public view, reminding workers that the bill arriving in their name is not always theirs to pay. The law, it turns out, has long drawn a line between personal obligation and employer negligence—most people simply never knew where that line was drawn.
- Millions of workers unknowingly absorb tax bills that their employers were legally required to prevent in the first place.
- The confusion runs deep: when a tax notice arrives in your name, the instinct is to pay it—but that instinct may be costing workers money that isn't theirs to owe.
- Labor lawyer Juanma Lorente and tax specialist Julia Coronel are using social media and public commentary to close the awareness gap, one worker at a time.
- The protection is real but conditional—it only applies when the employer genuinely failed to meet their legal withholding obligation, not when correct rates were applied.
- Workers are now being urged to audit their own withholding history and, where employer error is confirmed, formally demand reimbursement rather than quietly absorbing the cost.
Two legal professionals are spreading a message most workers have never heard: if your employer withheld less tax than the law requires, the resulting bill is the company's responsibility—not yours.
Labor lawyer Juanma Lorente brought the principle to public attention through a TikTok video, explaining that while the rule is clearly established in law, almost no one knows it exists. Tax specialist Julia Coronel echoed the point: when an employer miscalculates or underapplies withholding, the shortfall that surfaces at tax time should not fall on the employee.
The logic is grounded in legal obligation. Employers are required to calculate and apply the correct withholding rate for each worker based on their income and personal circumstances. When they fall short of that obligation, the error is theirs—and so is the debt. Coronel was clear that the company's liability is tied directly to their failure to comply with the law from the start.
There is an important boundary: this protection only applies when the employer actually made an error. If the correct amount was withheld and a balance still appears, the employee bears that responsibility. But when underpayment stems from company negligence, the worker has legal standing to demand the company cover it.
Both lawyers point to a widespread and costly assumption—that any tax bill bearing your name is yours to pay. Lorente and Coronel are working to replace that assumption with awareness, so workers know not just what they owe, but what they are entitled to refuse.
Two legal professionals are circulating a message that most workers don't know: if your employer withheld less tax from your paycheck than the law requires, the company—not you—should cover the bill when you file your annual tax return.
Juanma Lorente, a labor lawyer, posted a video on TikTok laying out the principle plainly. The rule exists in the law, he explained, though few people are aware of it. Julia Coronel, a tax specialist, confirmed the same point: when an employer fails to withhold the correct amount, the resulting tax liability that appears on your return shouldn't fall to you.
The mechanism is straightforward. Employers are legally obligated to withhold a specific amount of tax from each paycheck based on your circumstances and income level. When they withhold less than required, that shortfall becomes your problem at tax time—unless you know the law says otherwise. Coronel emphasized that the company bears responsibility for the error. They were required by law to calculate and apply the correct withholding from the start, tailored to your individual situation.
The catch is that this protection only applies when the employer actually failed to meet their legal obligation. You can't claim the company should cover your bill if they withheld what the law required; the company's liability exists only when they underpaid. But when that underpayment is their mistake, the debt is theirs to settle, not yours.
Both lawyers stressed that this is a widely overlooked provision. People routinely assume that whatever amount appears due on their tax declaration is their responsibility to pay. The assumption is understandable—the bill arrives in your name. But the law draws a distinction: if the company didn't do its job correctly, the company pays the consequence. Lorente and Coronel are trying to shift that awareness, one video and conversation at a time, so workers understand what they're actually entitled to demand.

This is something very few people know about, but it's in the law— Juanma Lorente, labor lawyer
The company should have applied the correct withholding according to the law and your circumstances— Julia Coronel, tax expert
The Hearth Conversation Another angle on the story
Why would a company ever admit they underpaid withholding? Wouldn't they just let the worker deal with it?
They might try. But the law is clear—it's not optional. If you can show they withheld less than they were supposed to, you have a legal claim against them, not just a polite request.
How would someone even know if their employer got the withholding wrong?
You'd see it on your tax return. If you're owed money back, that's one sign. But if you owe money, and you know your income and circumstances haven't changed dramatically, that's when you should ask: did my employer withhold correctly?
And if the company refuses to pay?
Then you have grounds for a labor dispute. That's where lawyers like Lorente come in. It's a legal obligation, not a favor.
Is this rule the same everywhere, or does it vary by region?
The lawyers in this story are speaking about Spanish law specifically. Every country has its own tax code, so you'd need to check your own jurisdiction. But the principle—employer responsibility for correct withholding—is pretty universal.
Why isn't this taught more widely?
That's the frustration both lawyers expressed. It's in the law, but it's not common knowledge. Most people assume tax bills are their problem. Changing that requires people like Lorente and Coronel to keep talking about it.
