A change in the assets of a natural person may result in the need to include increases or decreases in assets in the tax return.
Gain or loss of assets.
According to personal income tax regulations, the alteration of an individual's assets can lead to a gain or loss of assets.
In the case of the sale of a home, the capital gain or loss is the difference between the transfer value of the home and the acquisition value, understood:
Acquisition value: value for which the property was acquired plus the expenses inherent in the acquisition, such as commissions, public deed, registration, etc.; and taxes inherent in the acquisition (Transfer Tax and Documented Legal Acts, VAT or Inheritance or Gift Tax if the acquisition is made by inheritance or donation).
Sales value: the value by which the property has been transferred, discounting the expenses and taxes inherent to the transfer (provided they are paid by the transferor).
From January 1, 2015, the home's purchase value cannot be updated with the CPI accumulated since the purchase. However, in cases where the dwelling was acquired before 31 December 1994, it could apply a transitional regime of abatement or reduction of capital gains.
