The tax authorities will refund part of what you pay for new windows in your income tax return, provided you meet a few simple requirements. We'll explain it to you without the fine print.<\/p>\n<h2>What has happened to the tax deduction for replacing windows?<\/h2>\n<p>These deductions were suspended at the beginning of 2026, but the <strong>Royal Decree-Law 7\/2026, of March 20<\/strong>They were reinstated with effect from January 1, 2025. Congress ratified it at the end of March, so it's now final. The key dates are these:<\/p>\n<ul>\n<li><strong>Home renovations:<\/strong> You can deduct those made up to the <strong>December 31, 2026<\/strong>.<\/li>\n<li><strong>Energy certificate after construction:<\/strong> must be issued before <strong>January 1, 2027<\/strong>.<\/li>\n<li><strong>Works throughout the building<\/strong> (those contracted by the community): until December 31, 2027.<\/li>\n<\/ul>\n<p>In other words: if you want to take advantage of it for your apartment, this is the last stretch of the year to do so.<\/p>\n<h2>How much can you deduct?<\/h2>\n<p>There are three sections. The one that best suits a window replacement is the first:<\/p>\n<ul>\n<li><strong>20% of the investment<\/strong> (up to \u20ac5,000 per year base, i.e., up to <strong>\u20ac1,000 deduction<\/strong>) if the work reduces at least one <strong>7% of the demand for heating and cooling<\/strong> of the home. Replacing old windows with energy-efficient ones is exactly the kind of work that achieves this.<\/li>\n<li><strong>40 %<\/strong> (up to \u20ac7,500 base per year, up to <strong>3.000 \u20ac<\/strong> (deduction) if non-renewable primary energy consumption is reduced by at least 30% or the home reaches an A or B rating. It usually requires combining windows with other improvements, such as changing the heating system.<\/li>\n<li><strong>60 %<\/strong> for energy rehabilitation works of a <strong>entire building<\/strong>, with a maximum accumulated amount of \u20ac15,000 per owner.<\/li>\n<\/ul>\n<h3>A simple example<\/h3>\n<p>You replace all the windows in your apartment and the bill is \u20ac6,000. If the technician certifies that the heating and cooling demand decreases by at least 7%, you get a 20% discount on the maximum of \u20ac5,000. <strong>\u20ac1,000 less on your tax return<\/strong>Add to that the savings on your electricity bill each month.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/ventanasypuertasbenidorm.com\/wp-content\/uploads\/2026\/09\/eficiencia-energetica-ventanas-benidorm-foto-1.jpg\" alt=\"Ventanas eficientes en un piso de Benidorm que permiten deducir en el IRPF\" width=\"1600\" height=\"1067\" loading=\"lazy\" \/><\/p>\n<h2>Requirements for the Tax Office to accept it<\/h2>\n<ul>\n<li><strong>Energy efficiency certificate before construction.<\/strong> It is done by a qualified professional (architect, surveyor, or engineer). A previous report is valid if no more than two years have passed since the start of construction.<\/li>\n<li><strong>Energy efficiency certificate after the work<\/strong>, which compares the result with the previous one and demonstrates the improvement.<\/li>\n<li><strong>Make it your primary residence<\/strong> or a property you own that you rent out as your primary residence (or that you put up for rent before December 31, 2027). If you use it as a holiday rental, consult your advisor first.<\/li>\n<li><strong>Pay by card or bank transfer<\/strong>Never in cash, and keep the receipt.<\/li>\n<li>If you receive any subsidy for the same work, it is subtracted from the amount you deduct.<\/li>\n<\/ul>\n<h2>Step by step to take advantage of it<\/h2>\n<ol>\n<li><strong>Request the initial energy certificate<\/strong> of your home (if you don't already have one).<\/li>\n<li><strong>Request a quote<\/strong>We'll look at your apartment, recommend the windows that best improve insulation, and give you the technical details the certifier needs.<\/li>\n<li><strong>We installed the windows<\/strong> and you pay by bank transfer.<\/li>\n<li><strong>The technician prepares the final certificate.<\/strong>, before January 1, 2027.<\/li>\n<li><strong>You claim the deduction<\/strong> in the income tax return for the year in which that certificate is issued.<\/li>\n<\/ol>\n<h2>Which windows help meet the requirement<\/h2>\n<p>The biggest improvement to the certificate comes from replacing old single-glazed or uninsulated aluminum windows with:<\/p>\n<ul>\n<li><a href=\"\/en\/ventanas-de-pvc\/\">PVC windows<\/a> with several chambers, which insulate very well and are not damaged by salt air.<\/li>\n<li><a href=\"\/en\/ventanas-de-aluminio\/\">Aluminum windows with thermal break<\/a>, if you prefer thinner profiles.<\/li>\n<li><strong>Double glazing with low-emissivity glass<\/strong> (or solar control on very sunny facades).<\/li>\n<li>Insulated roller shutter boxes, which are usually a large hole through which heat escapes.<\/li>\n<\/ul>\n<p>Besides the tax savings, you gain peace and quiet: in Benidorm, this is one of the improvements our clients appreciate most.

If the energy efficiency improvement is more significant (for example, new windows plus a heating system upgrade), it can reach 40%, up to \u20ac3,000.<\/p>\n<h3>Do I absolutely need an energy performance certificate?<\/h3>\n<p>Yes. Two certificates are required: one from before and one from after the work, to demonstrate that the property consumes less energy. Without them, the deduction cannot be claimed.<\/p>\n<h3>Is it valid for an apartment I have rented?<\/h3>\n<p>Yes, if it is rented as a primary residence or you rent it out before December 31, 2027. In the case of tourist rentals, consult your tax advisor first.<\/p>\n<h3>What if the homeowners' association replaces the windows?<\/h3>\n<p>If the work involves the energy rehabilitation of the entire building, there is a 60% subsidy, which is divided among the owners according to their share.<\/p>\n<h3>Can I pay in cash?<\/h3>\n<p>No. To be eligible for the deduction, payment must be made by card, bank transfer, or other banking means.<\/p>\n<p><em>General information based on Royal Decree-Law 7\/2026 and information from the Tax Agency.
