Troubleshooting and Requirements

What is the Income Tax Return (IRPF)?

The income tax return is the process by which taxpayers residing in Spain report their income, deductions, and family status to the Tax Agency to determine whether they owe a tax payment or are due a refund.

This procedure is filed annually and covers the previous fiscal year, with official deadlines published by the Tax Agency.

How We Help You File Your Income Tax Return

Personalized Review of the Draft

We review your official draft to identify errors in tax data, income, withholdings, and deductions that could affect the result.

Identification of Applicable Deductions

We review all the personal and family tax deductions you may be eligible for (housing, large families, rent, investments in cultural assets, etc.).

Accurate Calculations and Simulations

We run simulations so you can find out whether you’ll owe or receive a tax refund, and we explain how to minimize your tax liability within the law.

Secure presentation, either online or in person

We can handle your online filing through Renta Web, or we can accompany you if you need in-person assistance by appointment at the tax offices.

Official Deadlines and Procedures for Filing Income Tax Returns

According to the Tax Agency’s official tax calendar:

  • Tax returns for the previous tax year are filed from April through the end of June.

  • You can file your tax return online (Renta Web or Cl@ve/DNIe).

  • Phone support is also available by appointment.

  • You can file your tax return in person at a tax office by making an appointment.

These deadlines and procedures may change slightly from year to year, so we always update the information to help you meet them without any risk.

People who have obtained the following may also be required to:

Frequently Asked Questions About Income Tax Returns

In general, individuals who have exceeded certain income thresholds during the tax year are required to file a tax return. For example, individuals who have earned more than €22,000 from a single payer or approximately €15,000 if they have had multiple payers (according to the regulations in effect for the corresponding tax year). Individuals who engage in economic activities as self-employed workers or who have received certain capital income or capital gains must also file a tax return. Each case must be analyzed individually.

Yes. Self-employed individuals must file an income tax return, since they are subject to personal income tax based on the income earned from their economic activity. In addition, they must include the estimated tax payments made during the year and correctly adjust their income and deductible expenses.

Not always. Although the Tax Agency provides a draft, it may contain errors or fail to include all applicable deductions. Submitting it without reviewing it may result in paying more than necessary or making mistakes that lead to subsequent audits.

If you file your income tax return after the official deadline, surcharges, interest, or penalties may apply, depending on the length of the delay and whether you owe money or are due a refund. It is recommended that you file it within the established period to avoid penalties.

If the tax return results in a refund, the Tax Agency has a maximum of six months from the end of the filing season to issue the refund. In many cases, the refund is issued sooner, but that is the legal deadline.

The following are usually required:

  • DNI or NIE

  • Draft or tax information

  • Employment Withholding Certificates

  • Information on Rentals or Real Estate

  • Bank Account Information

  • Proof of deductions (family, disability, housing, donations, etc.)

For self-employed individuals, income and expense ledgers will also be required.

Yes. If you discover an error after filing your tax return, you can file an amended return or a supplemental return, depending on the situation. It is important to act quickly to avoid potential penalties.

The price depends on the complexity of the case (individual, self-employed person, multiple payers, rental income, investments, etc.). We always recommend requesting a quote in advance to find out the exact cost before we begin providing the service.

Tax deductions depend on your personal and family circumstances, as well as on state and regional regulations. There may be deductions for your primary residence, rent, children, large families, disabilities, charitable donations, and pension plans, among others. It is essential to review each case individually to ensure that the applicable deductions are correctly applied.

Yes, if you are required to file a tax return based on the established income thresholds, you must file the return even if it results in a refund. In that case, filing your tax return is the way to recover the amount that was withheld in excess during the year.

If the Tax Agency detects inconsistencies, it may send a notice or request asking for clarification or additional documentation. Having professional advice makes it easier to respond correctly and on time.

Yes, if you are married or form a household as defined by tax regulations, you can choose to file jointly or separately. In some cases, filing jointly is more advantageous, but this should be evaluated in advance using a tax simulation.

Yes. If you have received income outside of Spain, it is important to analyze your tax residency and any applicable tax treaties to avoid double taxation. This type of tax return requires a more detailed analysis.

Failure to file a tax return when required may result in financial penalties, surcharges, and interest. It may also cause problems with future tax refunds or applications for financial assistance.

Failure to file a tax return when required may result in financial penalties, surcharges, and interest. It may also cause problems with future tax refunds or applications for financial assistance.

Currently, most tax returns are filed online, either directly through the Tax Agency’s electronic portal or with the help of a professional. Filing in person may be advisable in complex cases or when you prefer a detailed, face-to-face review.
