Official assessment · DIAN

DIAN official assessment:
read the act and defend.

If DIAN notified an official assessment, start here: it is not a generic bill. It determines the tax (and often the penalty) and opens short deadlines for reconsideration or later nullity. Ligal is the Tax Law firm of Juan Santiago Rodríguez Prieto, ex-DIAN tax attorney. On Google it holds 5.0/5 with 26 reviews.

The thesis

Not just the amount. The act and the deadline.

An official assessment is how DIAN sets the tax when it rejects your private return or when you did not file. It may come from review or from assessment for non-filers. From notification, reconsideration deadlines run—and after that path, judicial nullity.

Ligal reads the act with ex-DIAN legal judgment and accounting proof when the objections are about figures. Juan directs the line; Jeysson and LIGAL Auditores join when supports decide the file.

When it is urgent

  • You were notified of an official assessment and the remedy clock is running.
  • There is an accumulated penalty or a questionable tax base.
  • You are unsure whether to reconsider, pay under protest, or prepare nullity.
  • You want a map before signing the remedy.

How we work

From the act to a defense map.

Reading the act, path, and proof—no filler that closes doors.

01

Reading the act

What DIAN determined, which facts it asserts, which rules it cites, and where the weak points are.

02

Path and deadlines

Whether reconsideration still fits, which term applies, and what happens when the path is exhausted.

03

Accounting proof

Supports, reconciliations, or expert work when the amount turns on figures.

04

Later strategy

Remedy, payment under protest, or preparing nullity and restoration of rights.

What we do not do with the assessment.

We do not challenge blindly

Without reading objections, deadlines, and proof there is no serious remedy.

DIAN or the court decides. We offer strategy, not miracles.

We are not a tax call center

High-ticket boutique. Case by case.

The edge

Defend like those who know the assessment.

FAQ

Official assessment, without fine print

It is the act by which DIAN determines the tax when it rejects your private return or when you did not file. It may be a review assessment or an assessment for non-filers, and it often includes a penalty.

From notification, the reconsideration term runs. The exact deadline depends on the type of act and how you were notified. The diagnostic fixes it with your file.

Juan Santiago Rodríguez Prieto, ex-DIAN tax attorney. If the objection is accounting, Jeysson Pulido or LIGAL Auditores join.

No. A strong reconsideration organizes the defense; it does not guarantee DIAN will revoke. Sometimes the path is nullity.
