What is Form 151, and how to submit it?
Understanding the tax implications of relocation is crucial for professionals and expatriates moving to Spain.
One key aspect of this is Form 151, which is directly linked to the Beckham Law—a special tax regime that can benefit eligible individuals significantly.
What is Form 151?
Understanding tax obligations for expatriates moving to Spain is crucial—especially for those benefiting from the Beckham Law, a special tax regime that attracts foreign professionals. One key requirement under this regime is Form 151 (Modelo 151), the official tax declaration form that enables eligible individuals to take advantage of the Non-Resident Income Tax (IRNR) benefits while residing in Spain.
This form requires taxpayers under this regime to declare their income and fulfil their tax obligations. This article explains what Form 151 is, who must file it, the deadlines, and how to circumvent common errors.
Main purpose of the 151 Form
Form 151 is the annual personal income tax return for individuals under Spain’s special expatriate tax regime, regulated by Article 93 of the Personal Income Tax Law (LIRPF) and Article 114 of its regulations (RIRPF).
This regime allows employees in Spain to be taxed as non-residents, applying a fixed 24% rate on income up to €600,000 and 47% on any amount beyond that. However, expatriates must pay taxes on all income earned in Spain and cannot claim the exemptions outlined in Article 14 of the Non-Resident Income Tax Law (TRIRNR).
Taxpayers benefiting from the Beckham Law should note that all personal income from work—whether earned in Spain or worldwide—is considered Spanish-sourced and must be declared on Form 151. While these individuals calculate their tax liability under Non-Resident Income Tax rules (with specific exceptions), they are still classified as tax residents of Spain and subject to Personal Income Tax.
As of January 1, 2023, the special tax regime under Article 93 has expanded to include remote workers, entrepreneurs, qualified professionals, and individuals engaged in training, research, development, and innovation. Additionally, family members—including spouses, minor children, and disabled dependents—can also qualify under this regime, even in the absence of a marital relationship.
Who needs to file Form 151?
Taxpayers must file Form 151 if they meet any of the following criteria:
They have opted for the special tax regime through Form 149.
They work in Spain and qualify under the Beckham Law.
They are not professional athletes, as they are excluded from the regime.
They have become administrators of an entity (excluding patrimonial entities).
They conduct economic activities in Spain classified as entrepreneurial, following the process outlined in Article 70 of Law 14/2013.
They are highly qualified professionals providing services to emerging companies or engaged in training, research, development, and innovation in Spain, provided that income from these activities exceeds 40% of their total income.
They are working remotely in Spain with a Digital Nomad Visa, either:
· Employed by a foreign company while working in Spain under an employer-employee contract.
· Holding an A1 form.
They are the spouse or children (under 25 years old) of a taxpayer under the expatriate tax regime.
When is the deadline for submission?
The deadline for filing Form 151 aligns with the standard personal income tax return deadline in Spain. Generally, it must be submitted by June 30 of the year following the fiscal year being declared. However, checking with the Spanish Tax Agency (Agencia Tributaria) for any specific extensions or changes that may apply in a given year is advisable.
How to submit the 151 form in Spain
Form 151 must be filed electronically through the Spanish Tax Agency’s online system. To submit the form, taxpayers must use one of the following electronic identification methods:
DNI-e (Electronic National Identity Document)
A recognised electronic certificate accepted by the Tax Agency
Cl@ve PIN (Spanish digital identity system for tax procedures)
Taxpayers should ensure their digital credentials are current before attempting to file to avoid last-minute issues.
Documents required for submission
To complete the filing of Form 151, taxpayers must provide the following documentation:
Tax Identification Number (NIF)
Details of all income earned in Spain
Proof of tax payments and withholdings made in Spain
Documentation related to rental income, if applicable
Information on real estate holdings in Spain
Capital gains details from the sale of assets or rights in Spain
Income earned abroad and any foreign tax paid for potential double taxation relief
Proper documentation helps prevent errors, ensures compliance, and facilitates the application of deductions where applicable.

Common mistakes when submitting the 151 Form
Taxpayers frequently make mistakes when submitting Form 151, which can result in penalties or unwarranted tax burdens. Some common mistakes include:
Failing to declare foreign-earned income while neglecting to apply the international double taxation deduction, which could otherwise reduce tax liability.
Not declaring rental income from properties in Spain. Under the impatriate regime, rental income from Spanish properties is taxable. For more details, refer to the Spanish Tax Agency’s consultation DGT V0560-21.
Not reporting the gains from the sale of assets or rights in Spain.
Incorrectly applying exemptions. The special tax regime does not allow exemptions under Article 14 of the TRIRNR.
Failing to declare dividends received from participation in Spanish companies.
Not reporting interest or other income derived from lending capital to third parties.
Misclassifying non-monetary compensation (income in kind) as tax-exempt when it does not meet the conditions outlined in Article 14.1(a) of the TRLIRNR.
Forgetting to deduct withholdings and advance tax payments made in Spain could result in overpaying taxes.
Incorrectly declaring the principal residence. Ruling 316/2024 from the High Court of Justice of Madrid establishes that a posted worker’s primary residence should not be taxable real estate income.
Earning income through a permanent establishment in Spain, except in cases explicitly allowed under Law 28/2022 (such as entrepreneurial activities or services to emerging companies and training, research, development, and innovation activities). In all other cases, having a permanent establishment would disqualify a taxpayer from the impatriate regime.
Not verifying liability for Wealth Tax. Some taxpayers may be subject to this tax under real obligation depending on asset holdings in Spain.
To avoid these common pitfalls, taxpayers should carefully review their filings, seek professional tax advice if necessary, and stay updated on regulatory changes that may impact their obligations under Form 151.

Consequences of not submitting the 151 Form
Failing to submit Form 151 on time or incorrectly declaring income can lead to significant financial and legal consequences.
- Late filing surcharges – If the form is submitted after the deadline without prior notice from the tax authorities, a progressive surcharge applies, ranging from 1% to 15%, depending on the delay.
- Interest on late payments – If additional taxes are owed, the taxpayer may be required to pay interest on the unpaid amount from the due date until full payment is made.
- Tax audits and inspections – The Spanish Tax Agency may initiate an investigation, potentially leading to further penalties and back taxes if undeclared income or incorrect filings are discovered.
- Fines for non-compliance – Failure to file can result in a fixed fine starting at €200, which may increase significantly if authorities determine an intent to evade taxes.
Potential fines and legal implications
If you do not submit your return within the voluntary period set by the Spanish tax agency, there are two consequence scenarios:
Scenario 1. Submission after the deadline but before a treasury notice
If you file Form 151 after the deadline but before receiving a formal request from the Spanish Tax Agency (Treasury), you will face the least severe consequences. In this case, a late filing surcharge applies, but no penalties for non-compliance.
Late filing surcharge calculation:
- A 1% surcharge will be applied for missing the deadline, plus an additional 1% for each complete month thereafter.
- If the delay exceeds 12 months, the surcharge is capped at 15%, and late payment interest will also apply.
- The surcharge may be reduced by 25% under certain conditions outlined in Article 27.5 of the General Tax Law.
- Filing as soon as possible helps minimise these extra costs and avoids harsher penalties.
Scenario 2. Filing after treasury notice.
The consequences become significantly more severe if the Spanish Tax Agency formally requests your tax return due to non-submission within the legal deadline. This is the most costly and least advisable scenario.
To avoid these severe penalties, taxpayers should never wait for a Treasury notice to file Form 151. Proactively filing, even if late, significantly reduces financial and legal risks.
If you identify errors or omissions after submitting Form 151, the correction process depends on whether the mistake benefits or disadvantages you as a taxpayer. There are two possible scenarios:
- Correction in favour of the taxpayer
If the mistake means you are entitled to a higher refund or owe a lower tax amount, you must file a rectification of Form 151 to adjust the return accordingly.
- Correction in favour of the Tax Agency
If the error results in a lower refund than originally claimed or an underpayment of taxes, you must submit a supplementary return to correct the discrepancy.
Additionally, a supplementary return is mandatory if any later circumstances arise that invalidate previously claimed deductions, reductions, or exemptions from an earlier return.
Promptly correcting errors ensures compliance and helps avoid potential penalties or tax audits.
