Who pays the IBI in a rental: what the contract should say

Who pays the IBI in a rental and why it matters to make it clear

The question is not only who bears the payment in practice, but whether that cost can validly be transferred to the tenant and how that clause should be drafted. In residential leases, the general rule under the Urban Leases Act is that the parties may agree certain expenses to be borne by the tenant, but with an important requirement: the agreement must be in writing and must specify the annual amount as at the date of the contract. The rule itself adds that, in no case, may the taxes associated with the dwelling be imposed on the tenant, unless that party has the status of taxpayer. This is set out in article 20 of the LAU in the consolidated text of the BOE: “The parties may agree… that the expenses… are to be borne by the tenant… [but] in no case may the taxes associated with the dwelling be imposed on the tenant, except in cases where that party has the status of taxpayer”. BOE, Law 29/1994, art. 20.

This means that the contract must separate two levels:

1. The contractual obligation to pay the IBI, if it is validly agreed.

2. The tax obligation to the Administration, which falls to whoever is the taxpayer under the tax.

These are different matters and it is important not to confuse them in the wording of the contract.

What the contract should say to pass on the IBI correctly

If you want the tenant to bear the IBI, it is not enough to use a generic phrase such as “taxes shall be borne by the tenant”. That formula is too imprecise for the standard required by article 20 of the LAU. The contract should identify the expense clearly and settle it from the outset.

### It should include, at a minimum:

1. An express reference to the IBI or, at the very least, to “the Real Estate Tax levied on the rented property”.

2. The allocation of payment to the tenant.

3. The annual amount as at the date of signing the contract.

4. The method of payment or adjustment if the bill is issued to the landlord.

5. A clarification that the agreement does not alter the status of taxpayer before the Administration, where that status corresponds to another party.

A clear clause avoids later disputes about whether the amount was the current one, whether surcharges were included, or whether the expense was truly agreed.

### Illustrative example wording

“The parties expressly agree that the tenant shall bear the annual amount of the IBI corresponding to the rented dwelling, which as at the date of this contract amounts to the figure shown on the latest available bill. This agreement is without prejudice to the status of taxpayer which, where applicable, legally corresponds to the party concerned vis-à-vis the Administration.”

This is only a drafting guide, not individual advice. If your contract has annexes, updates or previous agreements, it is advisable to check that there are no contradictions.

The tax point: agreeing payment does not change who the taxpayer is

This is one of the most common sources of confusion. If the contract says the tenant pays the IBI, that does not automatically mean that, before the Town Hall, the owner ceases to be the taxpayer. The LAU allows the passing on of the expense, but also makes clear that the agreement regarding taxes does not affect the Administration.

In practical terms:

1. The contract may internally allocate who bears the cost.

2. The tax obligation to the Town Hall is governed by the applicable tax rules.

3. If the tenant is not the taxpayer, the agreement does not make them the taxpayer by itself.

4. The landlord may remain the person who receives the bill or who must deal with municipal administration, even if the amount is then passed on to the tenant under the contract.

That is why, when drafting the clause, it is important to distinguish between “payment of the expense” and “tax obligation”. That precision prevents a clause that is valid in civil law from being interpreted as an improper alteration of the tax.

Common mistakes when agreeing the IBI in a rental

These are some mistakes worth avoiding:

1. **Using a generic clause**: “all taxes and expenses shall be borne by the tenant”. This can create doubts about what is included and whether the agreement meets the requirement to specify the annual amount.

2. **Failing to set the annual amount**: article 20 requires the written agreement to specify the annual amount as at the date of the contract.

3. **Mixing the IBI with other items**: community charges, insurance, utilities or fees may require different treatment.

4. **Forgetting the status of taxpayer**: the contract should not suggest that the tax obligation before the Administration changes.

5. **Repeating the clause without checking the actual bill**: if the amount changes or there are rebates, the contract may become out of step.

Practical steps before signing

1. **Check the latest IBI bill** and confirm the current annual amount.

2. **Decide whether you want to pass it on to the tenant** or bear it yourself as landlord.

3. **Draft the clause expressly** and separately from the other expenses.

4. **Identify the annual amount** as at the date of signature.

5. **Review the contract as a whole** so there are no contradictions with the expenses clause.

6. **Keep the bill and proof of the written agreement** in case any later discrepancy arises.

Practical conclusion

The short answer is this: in a rental, the IBI can be paid by the tenant only if the contract expressly agrees this, in writing and with the annual amount specified as at the date of the contract. In addition, you should bear in mind that the contractual agreement does not by itself change who is the taxpayer before the Administration. That separation between contract and tax matters is the key to avoiding disputes.

As a general guide, if the contract is simple, a well-drafted clause may be enough; if there are several properties, rebates, co-ownership or older agreements, it is advisable to review the wording case by case.
