ICIO and the licence tasa: two different charges
By Ross Alinari · Last checked · Editorial policy · How we check facts
ICIO is the municipal tax on qualifying construction, installations and works. A licence tasa is a separate local charge. Paying one does not demonstrate that the other has been dealt with, and neither payment is evidence that a construction proposal has planning approval. The national framework for ICIO appears in articles 100–103 of the TRLRHL; the applicable local ordinance supplies the municipal rate and administrative detail. This guide explains that framework without inventing a rate for any of the towns we cover.
Identify the taxable intervention
Article 100 addresses works requiring the relevant building or planning licence, responsible declaration or prior communication where their control belongs to the municipality. The taxable event is not avoided simply because the required licence has not been obtained. This distinction matters when reviewing an older renovation or a proposal described informally as too small to require paperwork.
Begin with the physical scope and the filing route, then identify the tax treatment that follows. Ask whether the quotation includes preparation of a cost breakdown suitable for the municipal submission and who will make the payment. If an owner already holds a receipt, check the property, reference and description against the current proposal. A receipt from an earlier job may relate to a different intervention. Keep the municipal tax file separate from the contractor’s invoice so the same payment is not accidentally counted twice when reviewing the overall project expenditure.
Use the correct cost base
The statutory base is the real and effective cost of the work, understood for this purpose as its material execution cost. Article 102 excludes VAT and analogous taxes, relevant local public charges, professional fees, the contractor’s business profit and other concepts that do not strictly form part of material execution. Applying the tax rate to the entire amount payable under every contract can therefore produce a misleading result.
Request a breakdown that distinguishes construction execution from professional appointments, taxes and other charges. A total headed renovation package is not enough to reconstruct the statutory base. Where several contracts are involved, retain a schedule showing their relationship to the same intervention. The aim is not to choose whichever subtotal is lowest, but to make the calculation traceable to the ordinance and the actual work. If the municipality uses a prescribed assessment method for its provisional calculation, record that method alongside the submitted budget and keep the later final assessment distinct.
Find the municipal rate and ordinance
Each municipality fixes its ICIO rate, subject to the statutory maximum of 4%. That ceiling is not a universal rate and should not be published as the rate for Dénia, Benissa or any other town without checking its ordinance. Article 103 also allows certain benefits where adopted and regulated locally; their existence in national legislation does not mean every application qualifies.
Obtain the current fiscal ordinance, its publication details and any relevant amendments. Check the effective date against the intended tax event and read the application conditions for any relief being considered. A promotional summary or an old contractor’s spreadsheet is not sufficient evidence of the current local position. Where the rate cannot be verified, leave the figure open and request the actual source before committing to a calculation. This is why our town-specific licence pages require a checked official bulletin reference rather than copying the same percentage across the coast.

Allow for provisional and final assessment
ICIO accrues when the construction, installation or work starts, even if the corresponding licence has not been obtained. Article 103 provides for a provisional assessment using the submitted budget or the ordinance’s indices or modules, followed by adjustment after the work according to its real and effective cost and the municipal check.
Treat the initial payment as part of an ongoing file. Retain the original budget, revisions and completion cost information needed to explain the final scope. If the work is reduced, expanded or cancelled, establish how the relevant municipality requires that to be recorded; do not assume that a contractor’s revised invoice automatically updates the tax file. An owner abroad should know who will receive later communications after the builders have left. Keep the contact and document arrangements active through close-out so a final assessment is not missed simply because the physical work appears complete.

Keep the tasa and other fees visible
The TRLRHL provides the framework for local fees, including urban planning services in the circumstances it specifies. The amount and calculation of the applicable tasa need the municipal ordinance. The ICIO base expressly excludes relevant local public charges, which is another reason not to merge every council payment into one unexplained allowance.
Ask for a schedule identifying the construction tax, the planning fee and any separate public-space charge relevant to the proposal. Distinguish a fee from a refundable security where the local procedure requires one, without assuming that every town uses the same arrangement. Professional fees are another separate category: their scope should explain the design, submission and supervision services being commissioned. An owner comparing quotations can then see whether a council payment is included, paid directly or still awaiting confirmation. No indicative monetary allowance is provided here because an unsupported range would hide precisely the local differences that need to be checked.

Build a readable remote-owner record
Article 101 identifies the taxpayer by reference to ownership of the work in the sense of bearing its cost, and addresses substitutes where another party applies or carries out the work. A contract should make clear who prepares, submits and pays the relevant documents; an informal assumption that the builder will handle everything can leave the owner without a usable record.
Maintain a simple register of the ordinance version, filing reference, calculation, payment evidence and outstanding final adjustment. Match each receipt to the property and the construction scope. When a variation changes the expected execution cost, ask whether it affects the provisional calculation or information needed at close-out. This document trail is particularly useful when the owner cannot attend the municipal office personally. It also keeps the construction quotation transparent: our sequence is a free estimate followed by a fixed-price quote after a site visit, with the treatment of taxes and professional appointments stated in the agreed scope.
Worked example
A hypothetical extension has an execution budget, a separate design appointment and a VAT charge. The owner asks for the ICIO calculation to identify the material execution base and the verified municipal rate. The design fee and VAT are not simply added into that base. At completion, the actual work differs from the provisional budget, so the owner retains the final cost evidence for the municipal adjustment. No town rate or project price is assumed.
