What is the Tax on Economic Activities (IAE) in Spain?

The Impuesto sobre Actividades Económicas (IAE), or the Economic Activities Tax, serves as a pivotal component of the Spanish tax framework, targeting the commercial endeavors of entrepreneurs, professionals, and companies. This local tax is imposed on any entity or individual engaging in business, professional, or artistic activities within Spain’s borders. The IAE’s purpose is twofold: it reflects the economic capacity of the taxpayer and plays a vital role in municipal financing.

Administered jointly by municipal councils and state tax authorities, the IAE tax rate is determined by a myriad of factors including business size, location, and the specific nature of the economic activity conducted. As a yearly financial obligation, it requires careful attention from all taxable entities to ensure compliance with local and state regulations. This article aims to shed light on the essentials of the IAE tax in Spain, providing clarity on liability, calculation methods, and potential exemptions to equip businesses with the knowledge needed for adept fiscal management.

Understanding the IAE and navigating the Spanish tax system can be overwhelming. At Lawants, our expert tax consultants simplify these complexities, offering tailored advice that ensures your business is compliant and strategically positioned. Contact us to discuss your tax planning needs.

IAE tax structure in Spain

The structural design of the IAE tax in Spain is methodically segmented to encompass the diverse range of economic activities across the nation. It is classified into three distinct sections corresponding to business, professional, and artistic activities, each with its own set of tariffs and regulations.

These classifications are further subdivided into divisions, groupings, groups, and headings, which facilitate the organization and precise categorization of economic endeavors.

  • Section 1 pertains to business activities, which are defined as operations conducted within a business organization involving the self-management of production means and human resources, or either of them. This section encompasses a spectrum of activities including independent livestock farming, mining, industrial operations, commercial enterprises, and service provisions. Independent livestock farming, in particular, is specified by certain conditions such as grazing habits and feed sources.
  • Section 2 is dedicated to professional activities. These are carried out personally by individuals who offer their skills and expertise independently. The essence of these activities lies in the personal capacity and attributes of the individual providing the service. When entities engage in such activities, they must register under an analogous activity in Section 1.
  • Section 3 covers artistic activities which can be undertaken by either individuals or entities. The IAE tax rate varies significantly based on the type of activity as well as the geographical location of the business. This intricate structure is further refined by the use of National Classification of Economic Activities (CNAE) codes that provide a standardized system for identifying the specific nature of each economic activity within the scope of the IAE tax.

Tariffs and rates: how much is the IAE tax and how to calculate it?

Determining the IAE tax requires a thorough understanding of its tariffs and rates, which are influenced by several factors such as the type of activity, the business location, size, and economic capacity. The calculation process involves multiple steps:

  • Classify the Business Activity: Each economic activity falls under a specific heading with a designated tax rate that can be either fixed or variable. This classification is crucial as it sets the foundation for the tax calculation.
  • Base Rate Determination: The taxable base of the IAE is established by law for each activity number and is subject to annual updates. Rates classify economic activities under different headings.
  • Application of Coefficients: The base rate may be adjusted by applying various coefficients:
    • Net Turnover Coefficient: Ranges from 1.29 to 1.35, based on the amount of turnover, and must be reported using form Modelo 848.
    • Location Coefficient: Municipalities may apply multipliers from 0.4 to 3.8 depending on the business premises’ location within the urban area.
    • Municipal Coefficients: The municipal minimum rate specified in official tables allows operation within that municipality. If multiple activities are conducted in one location, a minimum municipal fee is paid for each.
  • Provincial and National Rates: A provincial rate permits operation within a province, while a national rate allows for nationwide operations. These rates cater to specific activities and offer an alternative to paying municipal or provincial rates.
  • Additional Factors: For larger businesses, factors like employee numbers, contracted electrical power, or property cadastral value can influence the quota.
  • Rate “0”: In certain cases where tariffs lead to zero liability, no IAE tax is payable, negating the need to file form 840.

The intricacies of IAE tax calculation highlight the importance of accurate activity classification and awareness of local adjustments. Professional advice is often essential to navigate this complex process and ensure compliance with Spanish tax regulations. It’s important to note that bonuses or discounts may apply, such as a 50% founder discount during the first five years of operation.

Who has to pay the IAE business tax in Spain?

The IAE business tax in Spain applies to a broad range of economic actors, including entrepreneurs, professionals, and companies that engage in economic activities within Spanish territory. Both physical persons and legal entities are subject to this tax, with the obligation hinging on the scale of their operations.

Specifically, entities with a net amount of turnover (INCN) equal to or greater than €1,000,000 are required to register for and pay the IAE tax.

Entities that fall under this obligation include those operating directly in Spain as well as non-resident income taxpayers who conduct their business through a permanent establishment in the country and meet the turnover threshold. The calculation of INCN for tax purposes considers all economic activities performed by the entity. Additionally, for entities that are part of a group of companies, the INCN encompasses the total turnover of all entities within the group, regardless of accounting consolidation obligations.

Failure to register and comply with the IAE tax requirements can lead to penalties, underscoring the importance of understanding and adhering to Spanish tax regulations. It is essential for entities operating in Spain to be aware of their IAE tax obligations and ensure timely registration and payment. 

How to pay the IAE in Spain

Paying the IAE tax is an annual requirement for businesses operating in Spain, and understanding the process is critical for compliance. Below is an outline of how and when to pay the IAE tax:

How to Pay:

  • The IAE tax is paid on an annual basis.
  • Payment can be made at authorized bank offices or through electronic payment systems if available.

Who Collects It:

  • The tax is collected by the municipalities where the economic activity takes place.
  • Despite being a local tax, it is regulated by state legislation and is an integral part of the Spanish tax system.

When to File:

  • Upon starting a new activity, changes in business details, or cessation of activities.
  • For new activities, the registration statement must be presented within one month from the start date.
  • Variation declarations are due within one month after any changes occur.
  • Cancellation statements should be filed within one month of cessation of activities.

Forms and Declarations:

  • Taxable entities must notify the AEAT (Spanish Tax Agency) of registrations, cancellations, and changes using Form 840.
  • Non-exempt taxpayers with a net turnover exceeding €1,000,000 must also submit Form 848 and Form 036.
  • Exempt taxpayers are still required to notify changes using Form 036.
  • Temporary Unions of Companies (UTEs) submit Form 840 if subject and not exempt; otherwise, they use Form 036.
  • Taxpayers with a “0” quota are not required to present Form 840.

Payment Receipts and Tax Period:

  • Separate registration declarations are needed for each activity.
  • If paying municipal tax and operating multiple premises, declarations are required for each location.
  • The tax period typically aligns with the calendar year except for new registrations, cessations, or exhibitions.

Deadlines and Payments:

  • Payment deadlines vary depending on whether it’s a municipal, provincial, or national fee.
  • For registrations, tax assessments are notified individually to the taxpayer.
  • In subsequent years, payments are made by receipt.

Understanding these steps ensures that your business remains in good standing with Spanish tax authorities. It’s advisable to seek professional help from tax advisors like our experts at Lawants for assistance with these procedures and other related matters. Discover other spanish tax year deadlines.

What activities should be declared in the IAE?

When it comes to the IAE, transparency and compliance are key. All economic activities conducted on Spanish soil, even on an occasional basis, must be declared under the IAE, except for specific exempt sectors.

Activities must be classified according to the appropriate headings provided by the tax authorities.

It is important to note that even if a taxpayer engages in multiple activities, some of which may be subject to IAE while others are not, a declaration must be filed for all of them, including those that are exempt.

However, there are certain exclusions from the requirement to declare:

  • The sale of fixed assets belonging to your company that have been properly inventoried as such for more than two years before the sale.
  • The disposal of personal goods that have been in your private use for over two years prior to the sale.
  • Goods received as payment for personal labor or professional services.
  • The exhibition of items solely for decoration or adornment within a business establishment.
  • An isolated single retail sale.

Furthermore, primary sector activities such as agriculture, dependent livestock farming, forestry, and fishing are also exempt from filing IAE returns. It’s crucial for businesses to accurately identify and declare their taxable activities to avoid penalties and ensure compliance with Spanish tax regulations.

Economic Activities Tax (IAE) exemptions in Spain

The IAE in Spain offers a range of exemptions to support businesses and promote economic growth. These exemptions cater to different types of entities and activities, providing significant relief from this local business tax:

  • Newly Created Companies: Start-ups enjoy a breather with an exemption from the IAE for the first two tax periods. This exemption is not applicable if the activity was previously conducted under different ownership, such as in cases of mergers or business restructuring.
  • Small Entrepreneurs and Professionals: For individual entrepreneurs and self-employed professionals, an exemption is granted if their net turnover is less than one million euros. This threshold is subject to legal adjustments and should be verified annually.
  • Non-Profit Entities: Organizations that operate on a non-profit basis, including foundations, associations, and religious entities, are generally exempt from the IAE.
  • Specific Activity Exemptions: Certain activities are granted exemptions based on current legislation or municipal ordinances, which may vary by location and activity type.
  • Family Businesses and Special Cases: There may be reductions available for family-owned businesses and other special circumstances, highlighting the need for tailored tax advice.

It’s important to note that all natural persons, non-resident taxpayers with permanent establishments whose net turnover is below the threshold, public research organizations, educational establishments funded by public funds or recognized as non-profit, associations and foundations for people with disabilities, the Spanish Red Cross, and entities covered by international treaties are also exempt from the IAE.

For freelancers who have a business premise or employees, they are considered sole traders and are subject to classification under the IAE tables provided by the tax office. However, most companies end up being exempt from IAE tax due to these provisions.

Despite these exemptions, it’s mandatory to declare any economic activity before commencement to the Spanish tax authorities using forms Modelo 036 or 037. This includes specifying the IAE number corresponding to the economic activity from an official list. Whether you’re exempt or not, fulfilling these declaration requirements is essential for legal operation within Spain’s vibrant economy.

Are you entitled to a refund of the fee if you cease economic activities during the tax year?

In the event that your business activities come to a halt within the tax year, you may be eligible for a reimbursement of the IAE fee. The entitlement to a refund is based on the premise that the tax paid should correspond to the period in which the business was active. To initiate this process, it is crucial to:

  • Notify the Local Council: Promptly inform the local council where your IAE was registered about the cessation of your economic activities.
  • Submit an Application: Provide a detailed application for the IAE refund, including evidence of the ceased activity and its cessation date.
  • Attach Supporting Documentation: Any relevant documents, such as deregistration certificates, should accompany your application to substantiate your claim.
  • Await Review and Resolution: The local council will assess your request and, upon approval, will issue a refund proportionate to the duration when no economic activity was conducted.

The refund is typically calculated for the calendar quarters during which no activity took place, with the exception of the quarter in which you ceased operations. For provincial and national taxes collected by the Tax Agency, applications can be made online or submitted through various designated channels. However, for municipal taxes, applications must be directed to the local authority in charge of tax collection.

It’s imperative to stay informed about local tax regulations, accounting in Spain and adhere strictly to submission deadlines and procedures to ensure a successful refund process. Consulting with tax professionals can provide invaluable guidance in navigating these administrative tasks, allowing you to focus on what matters most—your business endeavors.

IAE Tax and CNAE: differences

Understanding the distinction between the IAE tax and the CNAE is essential for businesses operating in Spain.

The IAE, or Impuesto sobre Actividades Económicas, is a tax administered by the Tax Agency and is levied on economic activities conducted within Spanish territory. It is an indicator used primarily for tax purposes, reflecting the type of business activity and its economic capacity.

On the other hand, CNAE stands for Clasificación Nacional de Actividades Económicas, which translates to National Classification of Economic Activities. This system of codes is utilized to classify business activities across various administrative bodies other than the Treasury, such as Social Security. It is particularly relevant when a self-employed individual registers with the Special Scheme for Self-Employed Workers (RETA) or when engaging with different entities necessary for economic activity.

Each IAE code has a corresponding CNAE code. The primary difference lies in their application: the IAE identifies activities for tax purposes, whereas the CNAE is used for identification across other government agencies.

There are specific instances where both codes are required, such as in Form 390, the Annual VAT Summary, especially if subject to “prorrata” calculations that involve a mix of VAT-liable and VAT-exempt activities. For provisional “prorrata” calculations on form 036, businesses must identify the CNAE for each activity.

Should there be a need to ascertain which CNAE corresponds to your IAE, it can be done by reviewing official documentation from both the Treasury and Social Security or by consulting resources designed to match IAE codes with their respective CNAE classifications. This clarity in classification not only streamlines administrative processes but also ensures that businesses meet their reporting obligations accurately.


In summary, the IAE tax in Spain is a crucial element of the local tax system, imposing a levy on the economic activities of professionals, entrepreneurs, and companies operating within the nation’s borders. Understanding and adhering to the IAE tax requirements is not only a legal obligation but also a significant aspect of fiscal responsibility for businesses in Spain. Given the complexity of tax legislation, it is advisable for companies—particularly those new to the Spanish market—to seek professional guidance to navigate these waters effectively.Professional advice becomes indispensable when dealing with intricate situations that require an in-depth understanding of both national and local tax laws. Expert consultants can provide tailored solutions that align with your business’s unique needs and help avoid any potential pitfalls.

In closing, it’s important to recognize that the IAE tax plays a vital role in supporting local governments. The revenue generated from this business tax contributes significantly to funding public infrastructure, services, and amenities that benefit all residents and businesses alike. By complying with IAE regulations, businesses not only fulfill their legal duties but also contribute to the economic vitality and quality of life within their local communities in Spain.
