Spanish income tax and housing: the 45% myth and the aid that doesn't make homes cheaper

The complaint about Spanish income tax that fails at the basics: marginal is not the same as effective

A 40-year-old saver with €100,000 in the bank feels treated like a rich person with no help to buy their first home. The frustration is understandable, but the diagnosis of Spain's income tax (IRPF) contains a textbook error worth clarifying. The 45% is a marginal rate, not an average one: it only applies to the portion of income above €60,000 of taxable base. Someone earning exactly that amount doesn't pay €27,000, but around €17,900 — an effective rate below 30% before deductions. The confusion between marginal and effective fuels the myth that earning more isn't worth it.

The ICO guarantee: you pay, but to whom?

As for first-home aid, the ICO guarantee scheme covers up to 20% of the mortgage loan (25% in some cases). But some argue that this aid doesn't make housing cheaper, because with a rigid supply of land the benefit ends up being capitalized into the plot: the developer can bid higher, and the gain goes to whoever owns the land. The same would happen if VAT or municipal fees were removed: the discount never reaches the buyer; what's paid for land just goes up.

Taxes on housing: 40% or 25%?

It has often been repeated that 40% of the final price of a first home is taxes. A more detailed analysis corrects that downward: the real impact would be around 25%, depending on how the burden is split between construction, land and transfer. The deeper criticism may not be the amount, but where it hits: the system taxes building and moving, exactly what it wants to encourage.

The analysis leaves one question unanswered: if any aid turns into a land price premium, what would it take to make housing affordable? More supply, say some. Cutting taxes at the root, say others. The circle still doesn't add up.
