Frequently asked questions about income tax returns

When it is time to file income tax returns in Colombia, it is normal to have doubts about the steps to follow and how to avoid fines. Now that you know how the digital signature works, we will answer some frequent doubts about penalties that may be imposed by the Dian for errors associated with this process.

Penalty for late filing

Also known as penalty for untimeliness, it is applied when the citizen files the income tax return with the tax calendar already expired. This penalty involves the payment of interest in arrears and can be from 4 to 10% of the tax payable.

The longer the delinquency, the higher the amount to be paid. To avoid this penalty, the citizen may file the tax return during the tax calendar, as far in advance as he/she wishes.

Penalty for failure to report

As its name indicates, this is imposed by the Dian when a citizen does not file a tax return. Before sanctioning, the entity calls upon the citizen to complete the procedure and only pay the penalty for the expired term. If the taxpayer still does not file a tax return, the Dian may impose a fine of up to 20% of the taxpayer’s gross income.

Penalty for errors in the declaration

This is applied when the declarant, even though he/she has completed the procedure, presents errors that generate a lower tax to be paid. In this case, the tax return must be corrected and a penalty ranging from 10% to 20% of the total tax that was not paid by mistake must be paid. If the Dian finds multiple errors of this type, such as omission of assets or inclusion of liabilities that do not exist, the filer will be heavily penalized.

Penalty for filing and not paying

If the taxpayer made the declaration procedures, but did not pay the value of the amount, the situation may be subject to coercive collection. This means that the Dian will look for the citizen and not the other way around, adding interest for late payment. The situation may lead to seizure of accounts and real estate.
