The waste levy under Ley 7/2022: what councils need to know
Ley 7/2022: mandatory specific and non-deficit waste levy obligation by April 2025. Guide to calculate it using data from your municipal recycling centre.
Ley 7/2022: The new framework for waste levy in Spain
Since Ley 7/2022 de Residuos y Suelos Contaminados para una Economía Circular came into force, Spanish councils have had to face an important regulatory challenge: the implementation of a differentiated and non-deficit waste levy under Ley 7/2022.
This obligation is not merely another administrative procedure. It represents a fundamental shift in how councils must finance and justify their waste management services, particularly in infrastructure such as recycling centres. With the April 2025 deadline approaching fast, it is time for municipal technicians and environmental councillors to understand what this regulation truly means and how to implement it with real data.
What does Ley 7/2022 require regarding waste levies?
Article 11.3 of Ley 7/2022 establishes a clear obligation: councils must establish a specific, differentiated and non-deficit tax or patrimonial charge for the management of municipal waste.
It is important to break down what each of these terms means:
- Specific: the levy must be linked exclusively to the waste management service, differentiated from other municipal taxes or charges.
- Differentiated: there must be differentiation according to the type of waste producer (domestic, commercial, industrial) and possibly according to waste fractions or volumes generated.
- Non-deficit: revenues from the levy must cover all costs arising from the service, without representing an economic loss to the municipal treasury.
This obligation has a deadline: by April 2025, all Spanish councils must have a levy that meets these requirements. Many councils have already begun this process, but others are still in the initial stages of calculation and justification.
Costs that the waste levy must cover
One of the keys to designing a correct levy is knowing precisely what costs it must cover. Ley 7/2022 is clear on this:
| Cost concept | Description | Includes |
|---|---|---|
| Direct operation costs | Collection, transport and treatment of waste | Personnel, fuel, vehicle maintenance |
| Infrastructure | Recycling centres, sorting plants, landfills | Depreciation, maintenance, management personnel |
| Administrative management | Processing, inspection, levy collection | Personnel, IT systems, notifications |
| Closure and remediation costs | Landfill closure, contaminated land clean-up | Technical studies, execution of works |
| Environmental education | Awareness and prevention campaigns | Materials, events, communications |
The inclusion of all these concepts is essential. It is not just about covering door-to-door collection, but the entirety of the waste cycle until its final disposal or recovery.
Why data from recycling centres is essential
Those councils that have recycling centres possess an important advantage: they have very precise data on volumes and types of waste managed.
This information is invaluable for justifying the waste levy under Ley 7/2022:
- Recorded visits: allows segmentation by user type (domestic vs. commercial) and future demand estimation.
- Kilograms per fraction: provides a clear picture of which waste generates higher treatment costs (e.g., construction waste vs. paper).
- Seasonal variability: helps to size resources and budgets.
- Associated costs per fraction: some waste (RAEE, fluorescent tubes) has significantly higher management costs than others.
Recycling centre information also serves to justify to citizens and auditors why the levy has specific amounts. It is transparency based on real data, not arbitrary estimates.
Differentiation and incentives: design options
Ley 7/2022 allows councils to design differentiated tariff structures. This is not only permitted; it is advisable to guarantee fairness and promote circular behaviour.
Some options that councils may consider:
Differentiation by user type
- Standard tariff for single-family homes
- Reduced tariff for flats with verified selective collection system
- Special tariff for shops, restaurants or generators of larger volumes
- Differentiated tariff for SMEs that meet circular economy objectives
Bonus system for good practices
- Discounts for participation in domestic or community composting programmes
- Bonus for correct separation of fractions (verifiable through control systems)
- Tariff reduction for users who reuse materials or participate in repair events
- Incentives for shops that reduce waste generation
These incentives are not regulatory cosmetics; Ley 7/2022 expressly contemplates them as a tool to encourage the waste hierarchy: prevention, reuse and recycling.
Digital tools to calculate and justify the levy
A critical aspect that many councils initially overlook is how to collect, process and present the data necessary to calculate the levy.
Without appropriate tools, the process is manual, slow and prone to errors:
- Data scattered across spreadsheets in different departments
- Difficulty in correlating costs with managed volumes
- Lack of traceability in collection and expenditure
- Inability to audit the non-deficit nature of the levy
A digital recycling centre management platform, such as the one offered by TuPuntoLimpio, allows:
- Real-time recording of visits, weights and waste fractions
- Automatic generation of reports on costs per service
- Segmentation of analysis by user, period, waste type or location
- Maintenance of an auditable record of the calculation methodology
- Projection of future demand scenarios to adjust tariffs
This information is exactly what regional or state inspectors will review to validate that the levy is truly specific, differentiated and non-deficit.
Deadline and next steps for councils
With the April 2025 horizon set by Ley 7/2022, the time window is narrowing. Councils that have not yet started the process should consider the following sequence:
- Month 1-2: Collection of historical data on costs and waste volumes (last 3-5 years).
- Month 2-3: Analysis of costs per fraction, user and service.
- Month 3-4: Design of the tariff structure, including possible differentiation and incentives.
- Month 4-5: Public consultation (required) and preparation of supporting documentation.
- Month 5-6: Approval by full council and implementation of the collection system.
Councils that already have operational recycling centres have an advantage: they already possess or can easily generate the data to justify the levy. Those with manual recording systems should consider digitalising this information as soon as possible.
Conclusion: Real data for a fair levy
The waste levy under Ley 7/2022 is not a punitive imposition; it is a mechanism to ensure that waste management services are economically sustainable and transparent for citizens.
The key is that it be specific, differentiated and non-deficit — and that is only possible if it is built on real data, not on estimates or national averages. Municipal recycling centres, properly digitalised, provide exactly that information.
If your council is still in the process of designing or adjusting your waste levy, it is time to review whether you have the data to support it.

Frequently asked questions
What does it mean for the levy to be 'non-deficit' under Ley 7/2022?
It means that the revenue collected by the levy must cover at least 100% of the real costs of waste management in the council: operation, infrastructure, administration and environmental education. There cannot be an economic loss. However, the levy can be updated annually according to real costs.
Can a small council without a recycling centre comply with the waste levy under Ley 7/2022?
Yes. The obligation is to calculate a specific and non-deficit levy, regardless of infrastructure. What matters is documenting all waste management costs (collection, transport, treatment, personnel). A digital recycling centre facilitates the calculation, but is not mandatory to have one.
Can tariffs be differentiated according to waste type or user?
Yes. Ley 7/2022 not only allows but recommends differentiation of tariffs according to waste types, volume generated and type of producer (domestic, commercial, industrial). This promotes circularity and fairness in funding the service.
What is the average cost of a waste levy in Spain?
There is no single average cost because it depends on each council: size, available infrastructure, distance to treatment plants and waste composition. It can range from €50 to over €300 annually per household. This is why it is crucial to calculate according to real local data, not national comparisons.
What happens if a council does not approve the levy before April 2025?
Technically it breaches Ley 7/2022 and is exposed to administrative sanctions and reviews by regional authorities. Furthermore, it will have no legal mechanism to adequately fund waste management services from that date onwards.
How can you justify to citizens that the levy is not arbitrary?
By publishing the calculation methodology: what costs are included, what volume data was used, and how the amount is distributed among services. A recycling centre with digitalised data is the best transparency tool, allowing you to show kilograms managed, fractions recycled and associated costs.
