What Is Municipal Capital Gains Tax?
Municipal capital gains tax — legally referred to as the Tax on the Increase in Value of Urban Land — is a local tax on the increase in land value from the time of acquisition to the date of sale.
Key points to note:
- It applies only to the land value, not the building itself.
- Managed by the local town hall (ayuntamiento).
- Applicable to sales, inheritances, and gifts.
For property sales, this tax is an essential part of the total fiscal burden.
Municipal Capital Gains in Property Sales
This tax is only triggered if the land has increased in value. Recent legislation now ensures that no tax is owed if there is no real gain, provided this can be documented.
Before selling, you should analyse:
- Purchase price
- Sale price
- Cadastral land value
- Duration of ownership
For more detail, see our article How to calculate net profit when selling a property, which explains how municipal capital gains tax affects the overall proceeds.
How Is Municipal Capital Gains Tax Calculated?
There are two calculation methods under Spanish law, and the most favourable method should be applied.
1. Objective Method
Based on:
- Cadastral value of the land
- Years of ownership
- Legally defined coefficients adjusted by each municipality
2. Real Gain Method
Based on the actual increase in land value between purchase and sale.
If there is no increase, the tax may not apply.
At Ibiza Royal Agency, each transaction is assessed individually to ensure the most advantageous fiscal approach.
Who Pays Municipal Capital Gains Tax?
By default, the seller is responsible for the payment. However, parties may contractually agree that the buyer assumes the tax, which is uncommon and requires professional guidance.
Deadlines and Payment
The tax must generally be declared and paid within 30 working days of signing the notarial deed.
Late or incorrect filing may incur penalties. For practical guidance, see How to avoid tax penalties when selling a property.
