To understand Spanish Personal Income Tax, it is particularly important to distinguish between the average tax rate, the marginal tax rate and the top marginal tax rate. Unlike some other countries, Spain does not use a tax-class system. Personal circumstances are therefore not taken directly into account when determining the applicable tax rate. Instead, tax is calculated progressively using a system of tax brackets. 

Age-related allowances, child allowances and other tax reliefs are likewise calculated by reference to the relevant tax bracket. 

The national tax scale for 2024 is as follows:

1. The amount of €40,000 falls between €35,200 and €60,000. Tax of €8,725.50 is therefore payable on the first €35,200. 

 2. The remaining amount up to €40,000 (€40,000 - €35,200 = €4,800) is taxed at the rate shown in the right-hand column: €4,800 x 37% = €1,776.

 3. Finally, the two amounts are added together: €8,725.50 + €1,776 = €10,501.50.

Once the tax liability has been determined, the different tax rates can be explained as follows:

A) The Average Tax Rate

The average tax rate, also known as the effective tax rate, is calculated by comparing actual income before allowances with the amount of tax actually payable, including any payroll withholding or advance tax payments already made. In this example, the calculation is straightforward: €8,755 / €40,000 = 21.8%. The average tax rate therefore shows the proportion of your income that you effectively pay in tax.

B) The Marginal Tax Rate

The marginal tax rate is particularly important for tax planning because it indicates how much tax is payable on each additional euro of income. To determine this rate, taxable income must first be calculated and the bracket system then applied to that amount. In our example, taxable income after allowances and reductions amounts to €48,000. The next step is to identify the relevant bracket and read the applicable rate from the right-hand column. In this example, the income falls within the fourth bracket, between €35,200 and €60,000.

To calculate the tax, the fixed amount shown in the table (€8,725.50) is combined with the tax due on the remaining income at the rate shown in the right-hand column. This also means that each additional euro earned up to the next bracket (€60,000) is taxed at the marginal rate of 37%. If income rises from €40,000 to €42,000, the additional €2,000 would therefore be taxed at 37%, resulting in an additional tax liability of €740.

C) The Top Marginal Tax Rate

Because each additional euro of income is taxed at the marginal rate applicable to the corresponding bracket, this mechanism continues up to an income of €300,000. At €300,000, the highest bracket is reached and each additional euro is taxed at the marginal rate of 47%. As there is no higher bracket, this is also referred to as the top marginal tax rate. Where income exceeds €300,000, the total tax is calculated by applying the fixed amount in the table to the first €300,000 and the top marginal rate to the excess.

It should be noted that the top marginal rate is less than two percentage points higher than the preceding bracket. For this reason, the term "top tax rate" is sometimes also used in practice for taxable income from €60,000.

Use and Distinction of the Terms

The average tax rate shows how much tax you actually pay in proportion to your income.

The marginal rate and, where applicable, the top marginal rate show how much tax is payable on the final euro of income or on each additional euro earned.

In practice, the average tax rate gradually approaches the top marginal rate as income rises. However, mathematically, this does not mean that the taxpayer pays the top marginal rate on the whole income or that almost half of the entire income is paid in tax.

In the above example, taxable income of €40,000 results in the following rates: average tax rate: 21.8%; marginal tax rate: 37%.

 

Application of Regional Tax Rates and Precise Tax Calculation

As mentioned at the beginning of this article, the example applies only the national tax scale. In practice, however, depending on the taxpayer's place of residence, the tax scale of the relevant Autonomous Community is applied to half of the taxable income. As the regional scales may differ both in their tax rates and in the thresholds of the individual brackets, an accurate calculation requires the application of both the national and the regional scales to the corresponding halves of the income. The regional scales can be consulted on the website of the relevant Autonomous Community or on the website of the Spanish Tax Agency: [Regional tax]

Calculation of Spanish Income Tax

As an accurate calculation must also take account of the tax scale of the relevant Autonomous Community, personal allowances, joint filing by spouses, child allowances and other factors, an income tax Rechner may be used to obtain an approximate indication of the expected tax liability.
