New Build vs Resale in Spain: Which One Is Cheaper in Tax?

On tax alone, the new build vs resale in Spain question has a clear winner: a resale (second-hand) home pays ITP at 4%–11% of the price depending on the comunidad autónoma, while a new build pays a fixed 10% IVA plus AJD stamp duty of roughly 0.5%–1.5% — so on the same €300,000 home the new build's tax runs about €4,500 to €19,500 higher. That gap is real, but it is only one line. The new build comes with a 10-year structural warranty and no renovation bill; the resale is bought "as seen," with a six-month window to claim hidden defects (Código Civil, art. 1490).

The short version:

• A resale (vivienda de segunda mano) is taxed with ITP, set by each comunidad — 4% in País Vasco, 6% in Madrid, 7% in Andalucía, up to 10%–13% in Cataluña.
• A new build (obra nueva) is taxed with a national 10% IVA plus AJD of about 0.5%–1.5%, so its tax bill is higher than resale ITP in every region.
• On a €300,000 home, that tax gap ranges from roughly €4,500 in high-ITP Cataluña to €19,500 in low-ITP País Vasco.
• New builds carry a 10-year structural guarantee under the LOE; resales come with only a six-month hidden-defect claim.
• The lower-tax option is not automatically the cheaper home — renovation, energy rating, and the new-build price premium routinely flip the maths.

The new build vs resale decision in Spain gets framed as a lifestyle choice — shiny and turnkey versus characterful and central. Underneath, it is two completely different tax regimes, and most buyers only discover which one they triggered after the offer is signed.

Why the tax regime flips on new build vs resale

In Spain, a property purchase is taxed in one of two mutually exclusive ways, and which one applies has nothing to do with the price you negotiate. It depends entirely on whether the home has been lived in before.

A first transfer of a brand-new home, sold directly by the developer (promotor), is a commercial supply and falls under IVA (value-added tax). Every subsequent sale — any home that has had an owner — is a private transfer and falls under ITP (Impuesto sobre Transmisiones Patrimoniales). The two never overlap on the same deed.

What's the difference between IVA and ITP?

IVA is a national tax fixed at 10% for housing across all of Spain; ITP is a regional tax set by each comunidad autónoma, ranging from 4% to about 11%. IVA goes to the central treasury; ITP goes to the region, which is why the resale rate changes the moment you cross an internal border.

There is one more wrinkle that catches buyers out. On a new build, the notarial deed itself is also taxed — AJD (Actos Jurídicos Documentados, stamp duty) — because the transaction is under IVA. On a resale, the deed carries no AJD, because a deed already subject to ITP cannot be taxed twice. So the new-build buyer pays two taxes (IVA + AJD); the resale buyer pays one (ITP).

What taxes do you pay on a new build in Spain?

A new build is taxed at a flat 10% IVA plus AJD of 0.5%–1.5%, paid by the buyer — together roughly 10.5%–11.5% of the price. The IVA rate is set nationally by Spain's VAT law and confirmed by the Agencia Tributaria; the AJD rate is set by your comunidad (0.5% in País Vasco and Navarra, 0.75% in Madrid, 1.2% in Andalucía, 1.5% in Cataluña and the Comunidad Valenciana).

Two details matter in practice:

• The 4% super-reduced IVA exists only for officially classified social housing (VPO de régimen especial o de promoción pública) bought direct from the developer. It is a narrow exception — the vast majority of new builds pay 10%, and "this flat qualifies for 4%" is a claim to verify in writing, not assume.
• Buying off-plan (sobre plano) means paying in instalments as the building goes up, each one carrying its IVA, with the amounts you hand over legally guaranteed by a bank aval. Your money is protected, but your timeline is not — handover dates slip, and you cannot move into a tax advantage that hasn't been built yet.

What you pay on a resale: ITP, set by your comunidad

A resale is taxed only with ITP, and because each region sets its own rate, the same second-hand home can cost thousands more or less in tax depending solely on where it sits. As of 2026 the general rates run roughly:

Rates change, and freshness is the whole point of looking it up: the Comunidad Valenciana cut its general ITP from 10% to 9% effective 30 June 2026, and Cataluña moved to a banded 10%–13% scale on 27 June 2025. Most regions also publish reduced ITP rates — for buyers under 35, large families, or homes below a price cap (Andalucía drops to 3.5% for under-35s buying a habitual residence up to €150,000). Check your own comunidad and your own buyer profile before you make an offer; this is the single line that moves the most.

The same €300,000 home, taxed both ways

Hold the price constant at €300,000 and run it through both regimes. The new-build column is 10% IVA plus that region's AJD; the resale column is that region's ITP.

The pattern is clear: resale wins on tax everywhere, but the size of the win collapses as ITP climbs. In País Vasco the resale saves you nearly €20,000 in tax; in Cataluña, where ITP is already 10%, the new build is only €4,500 dearer — close enough that the warranty and the absence of a renovation bill can swallow the difference. Notary and registry fees (another roughly 0.3%–1% of the price) are similar for both and don't change the comparison.

Is it cheaper to buy a new build or a resale in Spain?

On tax, a resale is cheaper in every comunidad, because its ITP undercuts the new build's 10% IVA plus AJD. But "cheaper to buy" is not the same as "cheaper to own": the gap runs from about €4,500 in Cataluña to €19,500 in País Vasco on a €300,000 home, and a renovation or a poor energy rating can erase it within a year.

This is exactly where the listicle version of this question goes wrong. It stops at the tax table, declares resale the winner, and ignores the four costs that actually decide it.

The non-tax costs that flip the answer

The tax line is the loudest number, not the largest. Four others routinely change the verdict.

The 10-year warranty. A new build comes with statutory guarantees under the Ley de Ordenación de la Edificación (Ley 38/1999): 10 years for structural defects, 3 years for habitability faults, and 1 year for finish defects, counted from the building's reception. A resale has nothing equivalent. The seller is liable only for vicios ocultos — hidden defects — and the buyer has just six months from handover to act, a deadline that cannot be paused (Código Civil, art. 1490). A resale is, legally, bought "as seen."

The renovation bill. A new build needs nothing on day one. A resale priced at "segunda mano" rates frequently needs a kitchen, a bathroom, or rewiring — and those are the works that overrun hardest. If you are weighing a cheaper resale, price the renovation before the offer, not after, because renovation budgets blow past their estimate more often than they hold.

The energy rating. Older resale stock tends to sit at the bottom of the energy scale, and an E, F, or G energy certificate now affects the mortgage rate, the legal upgrade timetable, and the future resale price. A new build is delivered at A or B by construction code. That difference is a recurring cost the tax table never shows.

The price-per-square-metre premium. New builds typically command a higher price per m² than comparable resale stock — the developer's margin and modern construction are baked in — a split visible in the INE's separate house-price indices for vivienda nueva and segunda mano. A resale's lower ITP often reflects a lower price to begin with; you may be saving tax on a smaller number.

How buyers who get this right actually decide

The buyers who don't get burned do one unglamorous thing: they put both options into a single running total before they fall in love with either. New build at €300,000 means €30,000 of IVA, the AJD, the notary, no renovation, A-rated bills. Resale at €300,000 means lower ITP, but a €25,000 kitchen, an EPC upgrade, and a six-month defect clock. Side by side, the "cheaper" home is often the more expensive one — and you can only see it when every line lives in one place.

That is the gap a shared house-cost tracker like CasaTab was built for: log the price, the IVA or ITP, the AJD, the notary, the renovation quotes and the energy works against one purchase budget, and the true cost of each option stops being a guess. The same account can be shared with whoever you're buying with. For the full list of what else stacks on top of the tax — and what actually happens at the notary when you pay it — the true cost of buying a house walks through every line.

The honest bottom line

New build versus resale is sold as a feeling and settled by arithmetic. The tax regime flips entirely on which one you choose — a fixed 10% IVA plus AJD on the new build, a regional 4%–11% ITP on the resale — and on the tax line, resale almost always wins. But the warranty you forfeit, the renovation you inherit, and the energy bills you sign up for are real money too, and they fall on the resale far more often than the new build. Price all of it, in your comunidad, before you make the offer. The number that decides this is never the one on the listing.
