(Tax requirements, burden of proof and the new evidentiary standard)
It is not a sanction.
This is not an accusation.
It is not even necessarily a formal inspection.
It is a requirement.
And, for many internationally mobile people, that is the moment when everything changes.
The mistake of thinking that it is enough to explain it well
The most common reaction when a communication from the tax authorities arrives is to think:
“It’s okay, I explain it and that’s it.”
For years, that approach worked. It was enough to provide context, logic and a few documents to clarify the situation. Today, less and less.
Not because the administration is more distrustful than before, but because the environment has changed.
When explaining is no longer enough
A tax subpoena does not usually ask for opinions or stories. It asks for accreditation.
It’s not about telling where you lived, it’s about showing where you lived.
It is not a matter of explaining how many days you were in a country, but of proving it with solid evidence.
And that’s where many people realize that much of what they have:
- was generated a posteriori
- no verifiable date certain
- can be challenged without the need to prove it false
The problem of reconstructing the past
When the injunction arrives, the past has already passed.
Trying to reconstruct months or years later where you were, what you did and for how long involves leaning on:
- tickets
- contracts
- extracts
- captures
Documents that, although real, were not always created with their probative value in mind.
And the problem is not that they are fake.
The problem is that they are not unquestionable.
The question that changes everything
In many proceedings there comes a key moment when the administration stops asking what happened and starts asking something else:
Can it be shown that this evidence existed at the time and has not been altered since?
When that doubt arises, the burden of proof begins to shift.
And explaining well is no longer enough.
It’s not distrust, it’s standard
This change is not in response to greater hardness, but to a different standard.
Today:
- a PDF can be modified
- a history can be reconstructed
- a catch can be falsified
Not because someone has done it, but because it is technically possible.
And when something is technically possible, it is no longer accepted by default.
What is really expected from the taxpayer
Increasingly, what is expected is not a coherent narrative, but a solid evidentiary basis:
- evidence generated at the time
- demonstrable integrity
- consistent chronology
- third-party verifiability
Not as a reaction, but as a prevention.
The invisible cost
Even when everything ends up working out well, the process often involves:
- time
- resources
- uncertainty
- stress
And a recurring sensation:
To have done things correctly, but not to have tested them as required today.
A necessary reflection
The question is no longer whether you can explain it.
The question is whether you can prove it with guarantees, even when no one trusts the digital medium by default.
More and more professionals are rethinking how they document their activity and residency before the requirement arrives.
Because when the IRS asks for more than just explanations, it’s no longer the best time to start preparing.
And now, an honest question
If tomorrow you were to receive a request from the Tax Authorities asking you to prove your residence, your activity or certain specific periods…
Could you respond with on-the-spot, verifiable, hard-to-question evidence?
More and more people are rethinking how they build their tax evidence base before the summons arrives.
