Notary Cristina Clemente Buendia warned that heirs who undervalue inherited assets to save on taxes face severe future penalties and higher tax bills. Some people attempt to reduce their personal income tax or add artificial clauses created by legal gurus to avoid paying inheritance tax, but these practices often cause serious financial harm.
Clemente explained that declaring assets at the lowest possible value is one of the most common mistakes in inheritance management. While heirs might hope for immediate tax savings, Clemente stated that today's savings can easily become tomorrow's tax problem.
The central problem does not occur when heirs receive the property, but when they decide to sell it. The value declared during the inheritance process establishes the official acquisition cost of the building. Spain's tax agency, Hacienda, inspects these transactions and issues financial penalties whenever figures are calculated incorrectly.
Income Tax Rules for Inheritance
Clemente stated that heirs do not pay personal income tax when inheriting assets. Many people undervalue property due to false beliefs regarding how personal income tax and inheritance tax apply to inherited estates.
To illustrate the rule, Clemente described a case from her practice involving a widow and her two daughters who arrived to sign the inheritance of her late husband. She noted that across Spain, the tax for liquidating and dissolving joint marital property is zero euros.
Clemente added that there is also zero municipal capital gains tax and zero personal income tax on this marital property settlement. This tax exemption is codified under Article 33.2(b) of Law 35/2006, of November 28, on Personal Income Tax.
Because marital assets belong jointly to both spouses, liquidating the estate does not increase the surviving spouse's total wealth or generate a taxable financial gain. Consequently, declaring a minimum value during inheritance provides no tax savings at the time of transfer, but it drastically inflates taxable gains when selling the property later.
Clemente explained that tax authorities calculate capital gains by comparing the sale price against the acquisition value declared in the inheritance documents. If heirs set a very low initial acquisition value, the taxable capital gain and the resulting tax bill will be far higher when the property is sold.
Inheritance Tax and Regional Penalties
Inheritance tax is another major concern for individuals receiving an estate. Clemente noted that across most of Spain, inheritance tax receives heavy tax credits, with discounts reaching 99 percent or 100 percent in several regions.
However, four autonomous communities maintain higher inheritance tax rates than the national average: Asturias, Aragon, Catalonia, and Castilla-La Mancha. Even in regions with higher rates, heirs must calculate the tax amount accurately because public authorities impose financial penalties if undervaluation is detected.
In related guidance, legal expert David Jimenez noted that no article in Spanish law specifies a strict deadline for heirs to register inherited property under their own names.
Proper Inheritance Planning
Clemente recommended that heirs focus on proper inheritance planning rather than risky tax shortcuts. Accurate planning requires correctly valuing all received property and real estate before completing the transfer.
She also advised drafting a personalized will containing clear clauses and provisions designed to prevent future family disputes. Although proper planning requires time and professional legal counsel, Clemente emphasized that it protects heirs from severe tax problems.
