What is the chronological process for declaring and paying taxes when selling?

Immediate Tax Obligations at Point of Sale

The chronological tax process begins at the notary signing, where non-EU resident sellers face an immediate 3% retention on the gross sale price (AEAT regulations). This retention is deducted by the buyer and remitted directly to Spanish tax authorities as a prepayment against your final capital gains liability. For a €400,000 property sale, this means €12,000 is withheld at completion.

Spanish tax residents avoid this retention but must declare the gain on their annual Modelo 100 return, with capital gains taxed at progressive rates from 19% to 26% depending on total capital gains for the tax year (AEAT 2025).

30-Day Municipal Tax Deadline

Within 30 calendar days of completion, all sellers must pay Plusvalía Municipal (IIVTNU) at their local town hall. In Fuengirola, this typically costs €800–2,500 for most residential properties, calculated on cadastral value increases over your ownership period. Marbella rates run higher at €1,200–4,000 for similar properties due to higher cadastral valuations.

Missing this 30-day deadline triggers automatic penalties of 20% surcharge plus daily interest charges (Ley de Haciendas Locales). The calculation uses official cadastral value multipliers, not market values, making the tax predictable once you know your cadastral progression rate.

Quarterly vs Annual Capital Gains Declarations

Non-EU residents must file Modelo 210 within the quarter following sale completion. If you sold in January-March, your declaration deadline is April 30th; April-June sales require filing by July 31st. The actual capital gains rate is 19% on net profit after deducting purchase price, legal fees, and improvements with receipts (IRNR Act).

For a property bought at €300,000 and sold at €450,000 with €8,000 in deductible costs, your taxable gain is €142,000. At 19% rate, you owe €26,980 in capital gains tax. Since €13,500 was already retained (3% of €450,000), you pay an additional €13,480 on filing.

Spanish residents declare on their annual income tax return (Modelo 100) by June 30th following the sale year. They benefit from a €400,000 exemption if reinvesting in a new primary residence within two years, significantly reducing or eliminating the tax liability.

Professional Support for Complex Cases

Multiple property sales, inheritance situations, or properties held through Spanish companies require specialist tax advice due to different rates and declaration schedules. Properties owned for over 15 years by residents aged 65+ qualify for additional exemptions worth potentially tens of thousands in tax savings.
