Property Calculators
What it costs to buy, let and keep a home, starting from the cadastral value.
Spanish capital gains tax
What you owe on selling a Spanish home or shares, and the three routes to owing nothing.
Open calculator →Spanish Municipal Capital Gains Tax Calculator
Work out the plusvalía municipal, the tax a Spanish town hall charges when you sell, gift or inherit urban property. The calculator solves both methods the law allows, objective and real, and tells you which one costs less.
Open calculator →Spanish Property Transfer Tax Calculator
Work out the ITP, the transfer tax you pay when you buy a second-hand home in Spain, using your comunidad autónoma’s rate in force and the base the law has required since 2022: the Catastro reference value, not the price.
Open calculator →Spanish Property Tax (IBI) Calculator
Work out the IBI on your Spanish home from its cadastral value and your council’s rate, with the article 68 reduction if the value has been revalued, and a projection of what you will pay over the next nine years.
Open calculator →Spanish building tax
What part of your building quote is actually taxed, and what the tax comes to with your council’s own rate and reliefs.
Open calculator →Spanish Rent Withholding Return (Modelo 115) Calculator
Work out the withholding on your Spanish business rent, what you actually transfer to the landlord each month, and the quarter’s modelo 115 box by box.
Open calculator →Spanish form 180 calculator
How many records your lease generates, how the withholding base is split between several properties, when the return really falls due and what getting it wrong costs.
Open calculator →Spanish rent increase calculator
How much your rent can rise this year, under which index, when it starts to be payable, and whether the increase you were given was lawful.
Open calculator →Spanish waste fee calculator
What the Spanish rubbish bill comes to with your own town’s figures, who pays it when the home is let, and how long you have to appeal.
Open calculator →Spanish arras deposit
What backing out of a Spanish property sale costs, and why the same amount means three different things depending on what your contract says.
Open calculator →Spanish youth rent aid calculator
Whether you qualify, how much you would get a month, and how it differs from the Bono Alquiler Joven it replaced.

About the property calculators
Nearly every tax on a Spanish home starts from the same figure: the cadastral value, and increasingly the Catastro reference value. From it come the IBI you pay each year, the ITP on a purchase and the capital gains tax on a sale. If you let the place, the withholding and its annual summary appear too. These calculators walk that path step by step.
