Most foreign buyers find out the real tax bill afterthey’ve signed.
The agent doesn’t tell you
Real-estate agents earn commission on closing. Detailed tax breakdowns slow deals down — so they don’t produce them.
The lawyer arrives too late
By the time your lawyer reviews the deal, the arras is signed and 10% is at risk. The window for tax structuring has closed.
The gestor copies last year
Most gestorías copy-paste the previous filing. Edge cases, treaty credits, and structuring opportunities go unseen.
Dutch buyer · Orihuela Costa · €340k
The arras was about to be signed at a price that would have triggered an extra €12,400 in non-resident tax over the first three years.
We restructured the purchase before signing. The buyer kept the property, the saving, and the timeline.
The diagnostic that flagged this cost €347. The mistake it prevented cost €12,400. That’s the math.
Twenty years inside Spain’s tax administration.
Sarah spent two decades inside SUMA, Spain’s regional tax administration on the Costa Blanca — the same office that audits your Modelo 210, your ITP and your plusvalía. The diagnostic is built the way an auditor reads a file. That’s the edge.
Real cases. Real numbers.
Anonymised quotes from foreign buyers who started here before signing anything in Spain.
“The diagnostic flagged a Modelo 210 miscalculation that would have cost me €12,400 over three years. We renegotiated the purchase structure before signing the arras. Best €347 I have spent on this whole purchase.”
“My Irish lawyer is excellent but doesn't know Spanish tax. Sarah filled the gap exactly — ITP, Modelo 210, wealth-tax exposure, all in writing before I committed. Twenty years inside the tax authority shows on every line.”
“We started with the 30-minute call expecting a sales pitch. Got an honest 'don't buy this one' from Sarah's first look. Three months later we bought a different property through her full advisory. The trust was built in that first call.”
Quick answers.
I haven't found a property yet — is this still useful?
+
Yes — but the strongest version of this product is property-specific. If you're still searching, we recommend the €597 Property Analysis from Costa Larga, which evaluates a specific listing top to bottom, including tax. Once you have a target, the Tax Diagnostic is the right step.
What if I've already signed the arras?
+
Some structuring moves are still available before notary, but the savings window narrows. We'll be honest with you in the diagnostic about what's still possible.
Do you also file the taxes for me afterwards?
+
Yes, optional. The diagnostic is standalone, but most clients continue with our Tax Advisory line for ongoing Modelo 210, IBI and rental compliance. Pricing is separate and you decide after.
Refund — really?
+
Really. If the diagnostic doesn't identify at least €1,000 in savings, fee adjustments, or risks worth knowing, you reply to the delivery email asking for a refund and we issue it within 48 hours. We've never had to.
What's the difference between this and a full tax retainer?
+
This is one-shot, pre-purchase, written. A retainer is ongoing year-round filings. Most clients start here and decide on the retainer once they've seen our work.
