IRPF and capital gains on prime residential assets

The main national tax levied on the sale of a property by an individual resident in Spain is Personal Income Tax (IRPF). The capital gain or loss generated in the transaction is included in the taxpayer's savings tax base.

This capital gain is calculated as the difference between the transfer value and the acquisition value:

• Transfer value: The actual sale price, minus the expenses and taxes inherent to the transfer borne by the seller, such as estate agency fees or the amount paid for municipal capital gains tax (plusvalía municipal).
• Acquisition value: The original purchase price of the asset, plus the cost of investments and structural improvements carried out, together with the expenses and taxes paid at the time of purchase (Property Transfer Tax, VAT, notary, property registry and administrative agency fees). Accumulated depreciation is deducted from this amount if the property had been rented out.

Savings tax base bands

The calculated capital gain is taxed according to a progressive scale in the national and regional savings base:

1. Up to 6,000 euros: 19%
2. From 6,000.01 to 50,000 euros: 21%
3. From 50,000.01 to 200,000 euros: 23%
4. From 200,000.01 to 300,000 euros: 27%
5. Amounts above 300,000 euros: 28%

In high-value transactions, the majority of the capital gain usually triggers taxation at the top rate of 28%. For this reason, proper documentary evidence of all elements that increase the acquisition value is critical to determining the true taxable base.

Exemptions applicable under IRPF

Tax regulations provide for specific circumstances that allow the capital gain obtained to be reduced or exempt from taxation:

• Reinvestment in main residence: If the total amount obtained from the transfer is reinvested in buying a new main residence within a period of no more than two years (before or after the sale). If the reinvestment is partial, the exemption applies proportionally.
• Taxpayers aged over 65: If the property sold constitutes the taxpayer's main residence, the capital gain is fully exempt from tax without any requirement to reinvest the proceeds. In the case of a second home, a limited exemption applies if the proceeds are used to set up a life annuity within the timeframes and conditions governed by the IRPF Act.

Tax on the Increase in Value of Urban Land (Municipal Capital Gains Tax / Plusvalía Municipal)

The Tax on the Increase in Value of Urban Land (IIVTNU) is a direct local tax levied on the increase in value of urban land accumulated during the period of ownership. It is payable by the seller, unless expressly agreed otherwise or if the seller is non-resident in Spain, in which case the buyer acts as the taxpayer's substitute.

There are currently two methods for calculating the taxable base of this tax:

• Objective method: The cadastral land value at the time of transfer is multiplied by coefficients set by the relevant local council, based on the number of years passed since purchase.
• Direct estimation or real value method: The difference between the transfer value of the land and its acquisition value is calculated, applying the percentage that the land's cadastral value represents relative to the property's total cadastral value.

The taxpayer has the right to choose whichever calculation results in a lower tax bill. Furthermore, if the owner formally demonstrates that no actual increase in the value of the land has occurred (i.e. it was sold for less than its purchase price), the transaction will not be subject to this municipal tax.

Taxation of non-resident sellers (IRPFNR)

When the seller is not tax resident in Spain, the transaction is governed by Non-Resident Income Tax (IRPFNR) regulations.

Key features of this tax regime include:

• 3% withholding tax: The buyer is legally required to withhold 3% of the total agreed purchase price and pay it to the Tax Agency (Agencia Tributaria) using Form 211 within one month of the deed date. This amount acts as an advance payment towards the seller's final capital gains tax liability.
• Tax rates: Capital gains are taxed at a flat rate of 19% for tax residents in the European Union, Norway and Iceland, and 24% for residents in non-EEA countries.
• Final tax return (Form 210): Following completion, the seller must submit Form 210 within three months following the deadline for paying the withholding tax. If the 3% withholding exceeds the actual calculated tax liability, the non-resident seller is entitled to claim a refund of the excess from the Tax Administration.

Impact on Wealth Tax and the Solidarity Tax on Large Fortunes

Selling a high-value residential property transforms a fixed asset into financial liquidity or other investment instruments, altering the structure of the seller's personal balance sheet.

For tax planning purposes, it is necessary to consider the impact of two complex taxes:

• Wealth Tax (Impuesto sobre el Patrimonio): Properties are assessed at the highest of three values (cadastral, the value determined by the Administration for other taxes, or the acquisition price). After the sale, the generated liquidity will be assessed as of 31 December in bank account balances or in the valuation of financial investments held.
• Temporary Solidarity Tax on Large Fortunes: Acts as a complementary tax in autonomous communities where full or partial Wealth Tax relief exists, affecting net wealth exceeding the exemption thresholds established by national regulations.

Expense deductions and property renovations

To optimise tax settlement in high-value transactions, it is essential to distinguish between routine maintenance or repair expenses (which are not allowable for calculating capital gains) and works involving extension, refurbishment or improvement.

Deductible investments that increase the acquisition value include works resulting in an increase in living space, substantial energy efficiency improvements, or structural modifications to the building. Any renovation to be deducted must be supported by official invoices itemising VAT, bank proof of payment, and the relevant planning permissions processed with the local authority, such as those required in residential developments across Comunidad de Madrid.

Maintaining a thorough documentary file from the moment improvements are carried out prevents potential tax audits or administrative discrepancies later on.
