Then you have to deal with <i>la complementaria<\/i>. This is a formal requirement by the Spanish tax authorities to pay additional transfer tax because the declared purchase value is lower than the tax reference value.<\/b><\/p>\n<p data-path-to-node=\"4\">In this article, we explain how this procedure works, the impact of the new <a href=\"https:\/\/www.confianz.be\/en\/reference-value-in-spain\/\"><i>Valor de Referencia<\/i><\/a> (since 2022) and how you legally seal this.<\/p>\n<h2 data-path-to-node=\"6\">What exactly is la complementaria?<\/h2>\n<p data-path-to-node=\"7\"><b>La complementaria is a supplementary tax assessment issued by the Spanish tax authorities (<i>Hacienda<\/i>) imposed if they ruled that you were underpaid transfer tax (<i>ITP<\/i>) paid at the time of purchase.<\/b><\/p>\n<p data-path-to-node=\"8\">The law states that the tax authorities may check the tax value of a property. If the actual purchase price in the notarial deed is lower than the value set by the government (the <i>Valor de Referencia<\/i> or tax value)? Then the tax is calculated on that <b>higher government value<\/b>. The difference in tax, often plus interest, is recovered through this assessment. This is similar to a <a href=\"https:\/\/www.vlaanderen.be\/belastingen-en-begroting\/vlaamse-belastingen\/registratiebelasting\/belastingverhogingen-in-de-registratiebelasting\" target=\"_blank\" rel=\"noopener\">deficit assessment in Belgium<\/a>, but based on automated data.<\/p>\n<blockquote data-path-to-node=\"9\">\n<p data-path-to-node=\"9,0\"><b>Expert Quote:<\/b> \"Many buyers think the deal price is automatically the taxable base.  In Spain, the taxable base is the higher of the two: the market price or the reference value. Those who ignore this are guaranteed to get mail from the taxman.\" - <i>Confianz Team.<\/i><\/p>\n<\/blockquote>\n<h2 data-path-to-node=\"11\">Why are you receiving this additional tax assessment?<\/h2>\n<p data-path-to-node=\"12\">The reason lies in the difference between commercial reality and administrative valuation. Since the property crisis, 'bargains' can still be found in regions like Costa Blanca and Costa del Sol. For example, you buy a <i>resale<\/i> home at a competitive price.<\/p>\n<p data-path-to-node=\"13\">As a result, the Spanish government is losing revenue from the <b>ITP (Impuesto de Transmisiones Patrimoniales)<\/b>. To compensate for this, since 1 January 2022 the tax authorities have been applying a stricter system: the <b>Valor de Referencia<\/b>.<\/p>\n<h3 data-path-to-node=\"14\">The impact of the 'Valor de Referencia' (New Legislation)<\/h3>\n<p data-path-to-node=\"15\">Since 2022, the tax value is no longer subjectively estimated, but determined by the Spanish Land Registry (<i>Catastro<\/i>) based on actual sales figures in the area.<\/p>\n<ul data-path-to-node=\"16\">\n<li>\n<p data-path-to-node=\"16,0,0\"><b>The rule is simple:<\/b> You pay tax on the <i>Valor de Referencia<\/i>, unless the purchase price is higher.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"16,1,0\"><b>The risk:<\/b> Buying a property <i>under<\/i> this reference value? Then you will pay tax on a value you did not pay. If you do not do this spontaneously, it follows <i>la complementaria<\/i>.<\/p>\n<\/li>\n<\/ul>\n<h2 data-path-to-node=\"18\">Calculation example: The financial impact of an audit<\/h2>\n<p data-path-to-node=\"19\">To make the impact concrete, we outline a common scenario on the Costa Blanca.<\/p>\n<p data-path-to-node=\"20\"><b>Case study: Apartment in Calpe<\/b><\/p>\n<ul data-path-to-node=\"21\">\n<li>\n<p data-path-to-node=\"21,0,0\"><b>Actual purchase price:<\/b> \u20ac120,000 (A good deal).<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"21,1,0\"><b>Fiscal Reference Value:<\/b> \u20ac220,000 (Determined by the Land Registry).<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"21,2,0\"><b>Difference:<\/b> \u20ac 100.000.<\/p>\n<\/li>\n<\/ul>\n<p data-path-to-node=\"22\"><b>The taxman's calculation:<\/b> The registration tax (ITP) in the Valencia region is 10%.<\/p>\n<ul data-path-to-node=\"23\">\n<li>\n<p data-path-to-node=\"23,0,0\">You paid 10% at \u20ac120,000 = <b>\u20ac 12.000<\/b>.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"23,1,0\">Tax authorities claim 10% at \u20ac220,000 = <b>\u20ac 22.000<\/b>.<\/p>\n<\/li>\n<\/ul>\n<p data-path-to-node=\"24\"><b>The result:<\/b> You will receive a <i>complementaria<\/i> from <b>\u20ac 10.000<\/b> (the difference), plus default interest.<\/p>\n<p data-path-to-node=\"24\"><strong><a href=\"https:\/\/www.confianz.be\/en\/spanish-taxes-on-purchase-of-second-residence\/\">What taxes and fees do I pay when buying a property in Spain?<\/a><\/strong><\/p>\n<h2 data-path-to-node=\"26\">How can I avoid an additional assessment?<\/h2>\n<p data-path-to-node=\"27\">Avoiding an additional attack begins <b>before<\/b> signing the notarial deed.

The <i>Valor de Referencia<\/i> is a market-based value that specifically serves as a minimum basis for purchase taxes.<\/p>\n<p data-path-to-node=\"33\"><b>Can I object to la complementaria?<\/b> Yes, but the burden of proof is on you. You have to prove that the property is worth less than the Land Registry claims, for example due to structural defects. This requires a legally supported valuation report.<\/p>\n<p data-path-to-node=\"34\"><b>Does this rule also apply to new construction?<\/b> No. With new construction, you do not pay transfer tax (ITP), but VAT (IVA) and Stamp Duty (AJD). The <i>Valor de Referencia<\/i> is mainly relevant for existing construction (<i>resale<\/i>).<\/p>\n<p data-path-to-node=\"35\"><b>How do I know the tax value of my future home?<\/b> This value is publicly retrievable through the Spanish Land Registry's digital window (Sede Electr\u00f3nica del Catastro) using the property's cadastral reference.<\/p>\n<blockquote>\n<p data-path-to-node=\"37\"><b>About the author:<\/b> Glenn Janssens is a lawyer specialising in Spanish real estate transactions and tax regulations.
