What are progressive tax-exempt incomes?

Progressive exempt income is income that is not subject to taxation but influences the calculation of income tax. Although taxpayers do not pay tax directly on this income, it is taken into account when determining the applicable tax rate. In other words, it is income that, without being subject to taxation, must be taken into account for the purposes of calculating the tax rate applicable to the remaining income for the tax period.

In Spain, the current regulatory framework establishes how this income is managed and its impact on the taxable base. The tax treatment of exempt income is also relevant for expatriates, as it can affect their tax burden. If you are an expat and are finding out about income tax for foreign residents in Spain, this information is of interest to you.

Progressive exempt income in agreements

The easiest example to understand when we talk about progressive exempt income is the double taxation agreements signed by Spain.

The Tax Agency itself tells us that “exempt income with progressivity will be added to the general or savings tax base, depending on the nature of the income, in order to calculate the average tax rate applicable for determining the full state and regional tax liability.”

The average tax rate thus calculated shall be applied to the general or savings tax base, excluding progressively exempt income.

According to the Tax Agency, “Certain double taxation agreements signed by Spain establish that when income obtained by a taxpayer is exempt, in accordance with the provisions of the agreement itself, it must be taken into account for the purposes of calculating the tax rate applicable to the rest of the income obtained by that taxpayer during the financial year“.

Explanation and implications of progressively exempt income

We already know that progressively exempt income is a fundamental part of the Spanish tax system. Why? Because it has an impact on both general taxation and the specific taxation of each taxpayer.

If we look for a definition of progressively exempt income, it is income that is not subject to direct taxation. However, its inclusion in the calculation of the taxable base is necessary to determine the tax rate that will be applied to taxable income. 

We are talking about a phenomenon that establishes a relationship between exempt income and tax obligations, although the latter only affect income that is actually taxed.

Impact on the general and savings tax bases

Incorporating exempt income into the calculation of the tax base results in an adjustment to the total amount that will serve as a reference for calculating taxes. The general tax base is increased by the sum of untaxed income, which can significantly affect how the tax is applied to other income. 

For example, if a taxpayer has a tax base of 40.000 € and receives 5.000 € in exempt income, the new tax base amounts to 45.000 €, potentially altering their tax rate.

Relationship between exempt income and applicable tax rate

The Spanish tax system is characterised by its progressivity, which means that as the tax base increases, so does the tax rate. In this context, progressive exempt income, although not taxed, influences the rate that will be applied to taxable gains. 

With this in mind, tax planning strategy must take into account not only taxable income, but also how exempt income affects the calculation of the overall tax rate. This can be particularly relevant for expats and individuals with mixed income, as every exempt euro can change their future tax obligations.

Current regulatory framework in Spain

The regulation of progressive exempt income in Spain is structured at both the state and regional levels.

The basic regulations governing this income are found in the Personal Income Tax Law (IRPF). This law defines the tax treatment of various income items, including those that are exempt from taxation. Taxpayers need to understand how these exemptions apply to their tax returns.

Regional regulation and its influence on tax calculation

As we know, the autonomous communities in Spain have the power to establish their own tax regulations. There is therefore variability in exemptions depending on the autonomous community in which we find ourselves. Each region can modify the limits on exempt income and the applicable tax scales.

Double taxation agreements and their effect on exempt income

Spain has signed numerous international agreements to avoid double taxation. These agreements allow certain income earned abroad to be classified as exempt income, preventing it from being taxed both in the country of origin and in Spain. 

This is particularly relevant for non-resident expats and residents, as it helps them reduce their tax burden by preventing the same income from being taxable in two different jurisdictions.

Procedure for calculating the total tax liability with progressive exempt income

To begin the procedure, it is necessary to add the exempt income to the general taxable base or the savings taxable base. This step has a direct impact on the amount to which the tax scales will be applied.

The inclusion of this exempt income means that, even though it is not taxable, it is taken into account when establishing the taxpayer’s income tax threshold.

☑️​ Application of state and regional scales

Once the taxable base has been adjusted, the corresponding tax scales are applied. At this point, both the state and regional scales are taken into account, which vary depending on the region in which the taxpayer resides. 

The scales dictate the different tax brackets and, therefore, the amount to be paid based on the new taxable base, which includes exempt income.

☑️​ Calculation of the average tax rate

The average tax rate is obtained by multiplying the quotient between the calculated total tax liability and the total taxable base by 100. This percentage is crucial in the procedure, as it provides a clear picture of the effective tax burden borne by the taxpayer. Knowing this percentage makes it possible to assess whether the inclusion of exempt income has had a significant impact on the total tax liability.

☑️​ Determination of the total tax liability without including exempt income

Finally, it is important to calculate the total tax liability without taking exempt income into account. This allows for a direct comparison between the two situations and provides context on how this income has altered the taxpayer’s tax burden. 

Bear in mind that this analysis is very valuable in determining whether the tax treatment applied has been correct or whether there are aspects that need to be reviewed.

Practical example of calculation with exempt income and progressivity

Let us now look at a practical example to illustrate how exempt income is calculated with progressivity and its effect on personal income tax quotas.

Fictitious case with general taxable base and exempt income

Let us consider the case of taxpayer Mr. Pérez, who has earned 40.000 € in income from his work. To this amount is added 5.000 € in exempt income. To determine his total taxable base, the following calculation is made:

  • General taxable base: 40.000 €
  • Exempt income: 5.000 €
  • New taxable base: 45.000 €(4.,000 € + 5.000 €)

With this new taxable base, the total tax liability is calculated using the tax scales of both the State and the taxpayer’s Autonomous Community. Let us assume that the resulting tax liability, after applying the relevant tax scales, is 10.200 €.

  • State tax liability: 8.000 €
  • Autonomous Community tax liability: 2.200 €
  • Total tax liability: 10.200 € (8.000 € + 2.200 €)

To determine the average effective tax rate on the taxable base, the following formula is applied:

  • Average tax rate: (Total tax liability / New taxable base) x 100

In the case of Mr. Pérez, this means:

  • Average Tax Rate: (10,200 / 45,000) x 100 = 22.67%

This percentage represents the effective tax burden on his total income, which shows how exempt income can influence the determination of the tax rate applied to taxable income.

Tax implications for expats taxpayers

The tax implications for expats taxpayers are diverse, especially with regard to progressive exempt income. Their treatment is based on Spanish regulations, which have particularities that affect the tax payments of non-residents.

Treatment of progressively exempt income for non-residents

In the case of non-residents, exempt income may not be taxed in the same way as for residents. Generally, these taxpayers are taxed on their income generated in Spain, while their income from abroad is exempt if certain requirements are met. However, it is important to understand that the inclusion of exempt income may influence the applicable tax rate.

Effects of Spanish regulations on expats

Spanish tax regulations establish that expats are taxed based on their income earned in the country. Progressive exempt income can play an important role in this context. Therefore, despite not being taxed on this income, its consideration affects the structure of personal income tax. This taxable base can redefine the tax bracket in which other income is placed.

Specific considerations in international agreements

Double taxation agreements have a significant impact on expats. As we know, these agreements seek to prevent taxpayers from paying tax in more than one country on the same income. 

In the case of exempt income, this means that expats who are covered by an agreement may be exempt from tax in Spain on certain income, provided that they are covered by the specific regulations of each treaty.

  • Recognition of exempt income in the country of origin.
  • The possible deduction of taxes paid in the country of residence.
  • Specific regulations that may influence the tax burden.

Tax management and recommendations for international taxpayers

Focus on tax planning. This must be calculated in great detail if we are expats in Spain. Given that exempt income plays an important role in the calculation of income tax, the following should be considered:

  • Assess the nature of the income received and its classification as exempt.
  • Analyse how this income will impact the taxable base and the applicable tax rate.
  • Plan the distribution of income to maximise tax benefits.

Documentation and generation of the tax return PDF

Without proper documentation, we will not be able to file the income tax return correctly. This includes collecting and identifying all income, both taxable and exempt. The following information is required:

  • Certificates of withholding from salaries and other sources of income.
  • Documentation proving exempt income, such as receipts and invoices.
  • Registration and retention of any international agreements affecting taxation.

A PDF of the tax return can be generated using specific software that facilitates the compilation and submission of tax data.
