STUDY DESCRIPTION

  • What is being evaluated? Tax benefits are fiscal policy instruments that pursue certain economic and social objectives through exemptions, reduced rates, reductions or deductions in tax payments that generate incentives or improvements in the income of individuals and legal entities, which generally lead to lower tax revenues.
  • Objective: To evaluate some of these tax benefits in order to determine whether they fulfil the objectives for which they were created and to detect whether their existence is associated with any type of externality or distortion that would make it advisable to reformulate them. The study does not discuss the relevance or suitability of the economic policy objectives pursued by each tax benefit.
  • Scope, amount and time horizon: This study evaluates 13 tax benefits, with a total cost of approximately €35 billion in 2016 (the year in which the tax information was finalised at the time of this study), representing 60% of the total tax cost of all existing tax benefits.
  • Methodology and data: Elasticity estimation methodologies are combined with quasi-experimental counterfactual econometric impact analyses such as Diff-in-Diff, regression discontinuity and the development of fiscal microsimulators. To identify the findings, microdata from the universe of personal income tax returns, corporate tax returns and the family budget survey (EPF) for VAT are used in both cross-sectional and panel formats provided by the tax agency for the development of this assessment. In addition, the data from the personal income tax universe has been merged with the household consumption data from the EPF.

Findings and proposals

 The tax benefit for R+D+I shows a significant gap between the potential effectiveness of the tax benefit and its actual effectiveness
    Although the deduction percentages are high in international comparison, the maximum deduction limits play a limiting role, reducing the possibility of applying the deduction in full in each financial year, generating significant tax credits in the future and thus reducing the attractiveness of the incentive. For its part, the optional regime established in 2014 allows the limits to be exceeded or the deduction to be obtained in the form of a refundable deduction, but it has not proved as effective as expected, as a series of administrative requirements must be met for its application, which limit the attractiveness of this special regime.

Methodologies: descriptive statistical analysis, elasticity analysis, international benchmarking

  • Proposals
  • Organism
  • Status according to Agency
  •  
    Allow application for refundable deduction under the optional scheme
  • Ministry of Finance and Civil Service
  • Rejected

Allow the application for the refundable deduction under the optional regime in the same financial year in which the right to deduction arises (delete Article 39.2a of the Corporate Income Tax Law).

  •  
    Elimination of the obligation to maintain the overall average workforce
  • Ministry of Finance and Civil Service
  • Rejected

Eliminate the obligation to maintain the average workforce, or alternatively the workforce assigned to R&D&I activities, for 24 months in order to qualify for the optional regime (Article 39.2b of the LIS).

  •  
    Elimination of certain requirements established in Article 39.2 of the LIS in order to qualify for the optional regime
  • Ministry of Finance and Civil Service
  • Rejected

Eliminate some of the requirements established in Article 39.2 of the LIS in order to qualify for the optional regime and thus gradually bring the potential effectiveness closer to the actual effectiveness of the tax benefit and improve the attractiveness of the incentive among SMEs.

 Inconclusive evidence of VAT exemptions for health and education services

NOT CONCLUSIVE. If the exemption were lifted, the increased revenue obtained by the State in VAT could be offset by a higher cost of providing the service through the public system. The result is subject to the heterogeneous range of elasticities found in the estimate.

 No direct causal relationship has been identified between the tax deduction for donations and the increase in donations.

NOT CONCLUSIVE: no direct causal relationship has been identified between the tax benefit and the recent increase in donations, although analysis based on European surveys shows that the tax incentive is one of the five main factors that positively influence the decision to make donations.

 VAT exemption for financial services reduces the cost of financing for households and businesses

Lifting the exemption would increase prices as a result of the higher tax burden on financial products for households, and would not affect businesses as they can deduct the VAT they pay.

 The R+D+I tax credit does encourage investment in R+D+I, but there is room for improvement.

The evaluation concludes that the tax benefit does achieve the objective of promoting investment in R&D&I, which increases by €1.5 for every euro that the administration allocates to the tax incentive. This result is in line with those found in the most recent literature, which range between €1 and €1.5 for every euro of tax benefit. Thus, Guceri and Liu (2019) find a return of approximately one pound for every pound of lost revenue in the United Kingdom, rising to one and a half pounds in the case of small businesses. For its part, the OECD (2020) also finds a response close to one, being somewhat lower for large companies. Furthermore, according to the estimates in this study, a one percentage point increase in the deduction (e.g. from 25% to 26%) would increase companies’ R&D&I expenditure by approximately €110 million, representing an increase in the cost of the tax benefit to the state of €73 million (approximately). Of this amount, £36 million would become tax credit and only £37 million would be deducted in the same tax period.

  •  
    Establish a faster, semi-automated accreditation mechanism for low investments
  • Ministry of Finance and Civil Service
  • Implemented

Establish a rapid, semi-automatic R&D&I accreditation mechanism for companies whose R&D&I investment does not exceed a certain limit.

  •  
    Improve transparency, increase the information required and analyse the tax benefit within a comprehensive policy to support R&D&I.
  • Ministry of Finance and Civil Service
  • Rejected

Publish the list of legal entities benefiting from the tax incentive to bring their publicity into line with that required in programmes for direct transfers and subsidies to R&D&I, thereby improving transparency.
Increase the information requirements on the characteristics, composition of R&D&I expenditure and innovation results of beneficiary companies in order to better assess the effectiveness of the tax incentive. In particular, more information would be requested on the details of general R&D&I expenditure (beyond that subject to deduction), socio-economic characteristics and the financial situation of companies. Likewise, information on innovation results (patents, industrial design, etc.) should be included.
Analyse the tax benefit in conjunction with direct transfer and subsidy policies within the overall policy of support for R&D&I.

 Lack of coordination with the expenditure department affected by the tax benefit

Tax benefits are one of the instruments available for achieving certain economic policy objectives, so it would be appropriate to frame their assessment within the set of measures aimed at achieving those objectives. In particular, when drawing up recommendations, it is important to take into account the other measures in place at both national and regional level and to assess whether these benefits are the most appropriate instrument for achieving a specific objective.

Methodologies: documentary analysis

  • Proposals
  • Organism
  • Status according to Agency
  •  
    Comprehensive planning of public expenditure with ex ante and ex post evaluations
  • Ministry of Finance and Civil Service
  • Implemented

The creation or any modification of tax benefits must be framed within the strategic planning of the public policies to which they relate, so that the effectiveness of the different instruments can be assessed as a whole and the efficiency of different alternatives for achieving the proposed objective can be compared.
The formulation and reform of tax benefits, like other spending policies, must be accompanied by ex ante evaluations to determine the potential effects of the measures before they are adopted, and ex post evaluations after a few years to measure the degree to which the objectives have been met and, where possible, the efficiency with which they have been achieved.

  •  
    Administrative coordination
  • Ministry of Finance and Civil Service
  • Implemented

Coordination between different levels of government must be improved, particularly with regard to tax benefits and other state and regional economic policy instruments that pursue similar objectives, in order to achieve maximum effectiveness and efficiency in meeting the general needs of the population as a whole and the specific needs of each territory.

 Joint taxation fulfils its objective but discourages the second earner in the household from participating in the labour market.

The €3,400 reduction for joint taxation in the form of marriage achieves its objective of adjusting the tax to the composition of household income, particularly reducing the tax burden on families in which all income comes from a single member. However, its existence discourages the second income earner in the household (who is a woman in more than 80% of cases) from participating in the labour market, which exacerbates the gender gap problems in the Spanish economy.

Methodologies: descriptive statistical analysis, distributive analysis, regressions in discontinuity

  • Proposals
  • Organism
  • Status according to Agency
  •  
    Disappearance of joint taxation
  • Ministry of Finance and Civil Service
  • Rejected

Accelerate their gradual disappearance by establishing a transitional regime and offset the negative effect that the tax benefit will continue to have with new incentives for women’s labour participation that reduce the gender gap.

 The reduction for contributions to social security systems fails to encourage long-term savings.

The reduction of up to €8,000 for taxpayers’ contributions to various social welfare systems does not achieve its objective of encouraging long-term savings as a supplement to the public pension system. In fact, the assessment shows that the tax incentive may be negative for a large group of savers, once the taxation of benefits at retirement, pension plan fees and the intertemporal preference rate are taken into account.

    Reformulation of the benefit in accordance with the Toledo Pact recommendations
  • Ministry of Finance and Civil Service
  • Implemented

Completely reformulate the tax benefit for contributions to social welfare systems, in line with the recommendations agreed upon in the Toledo Pact on long-term supplementary savings.

 The reduction for employment income manages to boost the labour supply (small but significant effect).

The €5,565 reduction for earned income does achieve its objective of promoting low-income employment, mainly through the extensive margin (number of people working) rather than the number of hours (intensive margin). Specifically, for every million euros of increase in the total amount of the reduction, the final revenue cost would be €710,000. Twenty-seven per cent of the mechanical cost of the measure would be offset by the increase in the tax bases of those who move from not working to working (extensive effect), and the remaining 2% by the increase in the hours worked by those who were initially working (intensive effect).

 The reduction for residential leasing promotes the supply of rental housing.

The 60% reduction in net rental income DOES achieve its objective of promoting the supply of rental housing, although it has not been possible to differentiate between new supply and rents emerging from the informal economy. In addition, the evaluation identifies the growing difficulty for low-income households to access housing, especially in large metropolitan areas.

  •  
    Targeting incentives to facilitate renting for vulnerable groups
  • Ministry of Finance and Civil Service
  • Implemented

Reformulation of the incentive for reducing housing rental costs, reorienting its design to facilitate access to rental housing for vulnerable groups, taking into account the special needs in metropolitan areas. For example, by modulating the intensity of the incentive based on the housing rental index per census section of the Ministry of Transport, Mobility and Urban Agenda or registration as social rental housing.

 Reduced VAT rates facilitate access to basic necessities, but not in an efficient manner from a distributional point of view.

Lower taxation on certain goods and services through reduced VAT rates does facilitate access to essential, social, cultural or strategic goods and services and reduces the regressivity of the tax, although it does not achieve the objective efficiently from a distributional point of view.

Reduced rates, by lowering consumption taxes, benefit high incomes, which spend the most, to a greater extent. This effect is accentuated in those items of expenditure at reduced rates that are most consumed by high-income households (restaurants, package holidays, hotels, books, gardening, etc.), in which €5 billion in VAT revenue is lost.
In addition, the assessment highlights the distributive inefficiency when comparing reduced rates with other spending policies that are more focused on specific groups or sectors and that manage to reduce inequality much more than reduced rates while using fewer public resources.

Finally, the existence of a high proportion of expenditure at reduced rates explains Spain’s lower VAT revenue compared to our European partners.

 The difference in prices between diesel and petrol has led to a reduction in transport costs.

Tax difference in excise duty between diesel and petrol (non-professional use): The assessment concludes that the difference of €93.69 per 1,000 litres in taxation in favour of diesel HAS succeeded in favouring diesel in reducing transport costs, albeit with a negative environmental impact.

 The reduced rates applied to SICAVs and SOCIMIs lead to a high concentration among a limited number of shareholders, casting doubt on the collective nature of the investment.

The assessment is INCONCLUSIVE when it comes to determining whether the objective of promoting collective and diversified investment is being achieved in the case of SICAVs and real estate in the case of SOCIMIs, as there is insufficient information available to ascertain whether this is new investment or comes from other financial assets. Despite this, the assessment detects a high concentration of investment in the hands of a few shareholders, despite the reinforced requirements in Spanish regulations (a minimum of 100 shareholders), which casts doubt on the collective nature of the investment.
