It is regulated in the Código Civil del Perú, especially in the articles on responsabilidad civil (around Articles 1969 and following).
It includes:
Daño emergente → the actual loss (what was taken or lost).
Lucro cesante → the profit that the victim stopped receiving.
Daño moral → non-material harm (in some cases).
The basic rule:
Whoever causes damage to another through fault or intent must compensate.
That applies not only to private persons — it also applies when the State is the injured party.
2️⃣ Is tax evasion a “perjuicio”?
Yes — legally, it can be.
When someone evades taxes:
The State (Peru) is deprived of revenue.
That missing revenue is a patrimonial damage to the Treasury.
Therefore, it qualifies as perjuicio económico.
But here is the gateway:
In Peru, tax evasion is primarily a crime, not just civil damage.
It is regulated in the Ley Penal Tributaria.
That law establishes:
Criminal penalties (prison)
Fines
And importantly → civil reparation (reparación civil)
So the structure works like this:
AspectLegal FieldConsequenceFailure to pay taxes Administrative Interest, fines (SUNAT)
Fraudulent evasion Criminal Prison + fine
Economic harm to State Civil (within criminal case) Reparación civil
The perjuicio becomes the basis for calculating reparación civil.
3️⃣ Where is the “gateway” argument?
The legal bridge is this:
Tax evasion causes measurable economic damage to the State → that damage is quantifiable → therefore it generates civil liability in addition to criminal liability.
In Peru:
The Public Prosecutor requests prison.
The Procuraduría del Estado requests reparación civil.
That reparación is calculated based on the unpaid tax + damage + interest.
That is the “daños y perjuicios” doorway.
4️⃣ Why mention Al Capone?
Al Capone was not convicted for murder or organized crime.
He was convicted for tax evasion in the United States.
The lesson relevant to Peru:
When major crimes are hard to prove,
Financial damage to the State becomes the enforceable entry point.
The tax harm becomes the legally provable “perjuicio.”
5️⃣ Important distinction in Peru
Not every unpaid tax automatically equals criminal daño.
To become criminal tax evasion under the Ley Penal Tributaria, there must be:
Intent (dolo)
Fraudulent conduct
Exceeding legal monetary thresholds
Otherwise, it stays administrative.
But once it crosses into fraud:
➡ The unpaid tax is the perjuicio base.
➡ That generates criminal liability.
➡ And civil reparation (daños y perjuicios) attaches to it.
6️⃣ Clean legal formulation (the gateway phrase)
If you were drafting the argument in Peru, the key structure would be:
La evasión tributaria genera un perjuicio patrimonial directo al Estado, consistente en la privación ilegítima de recursos fiscales, lo cual configura daño resarcible conforme a las reglas de responsabilidad civil y habilita la imposición de reparación civil dentro del proceso penal.
That is the doorway.
No drama. Pure structure.
