Registering a Rental Contract in Spain for Tenants

Contract registration & taxes (RLI, ITP) 3 min read · published September 11, 2025
If you rent in Spain, it is normal to wonder whether the contract must be registered and what consequences this has for tenants and landlords. Registration affects taxes such as the Transfer Tax (ITP) or the Register related to the Urban Leases Act (RLI) depending on the autonomous community. In this practical guide we explain when registration is mandatory, what exemptions exist for temporary or corporate contracts, how it affects tax payment and what documentation to keep. We also detail steps to declare or challenge a settlement, and what rights tenants have regarding habitability, rent increases and evictions. You will find clear advice to act safely and use official resources.

When registration is mandatory

There is no single national rule that always requires registration of the rental contract; the obligation depends on regional regulations and the type of contract. The Urban Leases Act regulates basic aspects of renting but the registration procedure and fiscal consequences are applied differently by autonomous communities.[1]

In most regions, tenants are entitled to basic habitability conditions.

Taxes and exemptions

When a contract is registered or considered for tax purposes it may trigger obligations such as the settlement of Transfer Tax (ITP) or administrative procedures related to the property register. Some operations are exempt or subject to specific rules: short-term contracts, transfers between companies or certain seasonal leases may be excluded from registration obligation or taxation.[2]

  • Temporary or seasonal contracts are often exempt from registration in many regions.
  • Leases between companies may follow different rules than contracts between private individuals.
  • Assignment of the contract or subletting can involve tax obligations or notification requirements to the landlord.
Always keep a signed copy of the contract and proof of rent payments.

What to document and how to proceed

To protect your rights as a tenant, keep the contract, rent receipts, written communications and any proof of repairs or deficiencies in the dwelling. If you receive a tax settlement or a registration notice, request written information and, if appropriate, legal or administrative advice. In disputes about registration or taxes you can file objections or appeals with the regional tax authority or seek intervention from the Court of First Instance if there is a conflict over rights.

Respond to notifications within deadlines to avoid losing rights.

Practical steps for tenants

  1. Check the contract to confirm whether it includes clauses about registration or registration costs.
  2. Consult the regulation of your autonomous community or ask at the corresponding tax office.
  3. If registration or tax payment is demanded, request the receipt and verify who is obliged to pay.
  4. Keep evidence: signed contract, communications and payment receipts for any future claim.
