Form 210 for Capital Gains on Property Sales for Non-Residents

Taxation, 3% withholding and tax obligations after selling a property in Spain

The sale of a property in Spain by a non-resident can generate specific tax obligations that must be correctly managed following the transfer of the property.

One of the most relevant procedures is the declaration via Form 210 associated with the capital gains obtained, as well as the review of potential refunds related to the withholding tax applied during the sale.


At Aroca Seiquer & Asociados, we have been advising international property owners in Torrevieja, Orihuela Costa, and other areas of the Costa Blanca since 1988, supporting them throughout the entire post-sale tax process.

What is capital gains and when must it be declared?

When selling a property in Spain as a non-resident, a capital gain may arise from the difference between the acquisition value and the transfer value of the property.


This transaction generates specific tax obligations that must be declared using Form 210.

Please note

The 3% withholding tax on property sales by non-residents

When a non-resident sells a property in Spain, the buyer is generally required to apply a withholding tax equivalent to 3% of the sale price.

This amount acts as a payment on account towards the potential future tax liability arising from the transaction.

Key points:

Correctly analyzing the transaction prevents errors and ensures any applicable refunds can be claimed.

How we analyze taxation following the sale of a property

Each property transfer involves specific circumstances that influence the final tax liability.

Our analysis encompasses key factors such as:

  • Original acquisition value.
  • Expenses associated with the purchase and sale.
  • Renovations or capital investments made.
  • Joint ownership of the property.
  • Withholding taxes applied.
  • Potential capital losses.

A detailed study determines whether there is an obligation for an additional tax payment or an entitlement to a refund.

Common mistakes after selling a property as a non-resident

We frequently detect issues related to:

Unawareness of deadlines

Many individuals are unaware of the statutory timeframe available to correctly file the tax declaration following the sale.

Failure to claim eligible refunds

There are situations where sellers are entitled to recover part or all of the withholding tax applied.

Incorrect declarations

Errors in capital gains calculations can lead to subsequent tax disputes and penalties.

A specialized review helps minimize risks and guarantee full tax compliance.

Property sale, tax planning, and post-closing obligations

The sale of a property may involve additional tax considerations beyond Form 210.


Depending on the case, it may be necessary to review:

  • Future taxation as a non-resident.
  • Changes in tax residency.
  • Capital gains reinvestment.
  • Estate and succession planning.
  • Obligations tied to other properties retained in Spain.

For this reason, we approach each transaction from a comprehensive perspective rather than focusing solely on a one-time tax filing.
