Applying for the inbound workers regime requires following a specific process with the Spanish Tax Agency. The steps are clear, but the deadlines are strict and errors in the documentation can cost you the opportunity to benefit from one of Europe’s most advantageous tax regimes.

ToggleWhen can you apply for the Beckham Law?
The application must be submitted within the six months following the start of employment activity in Spain or, where applicable, from the date of registration with Social Security or the equivalent social welfare mutual fund. This deadline is absolutely non-extendable: once it has passed, there is no mechanism to recover it.
Correctly calculating the starting point of the deadline is essential. The start of activity may not coincide exactly with the date of arrival in the country, the signing of the contract, or registration in the municipal census. If in doubt about when the deadline starts running, the most prudent course is to start the process as soon as possible and consult a specialized tax advisor.
It is important to bear in mind that this procedure is independent of other administrative processes such as the application for a NIE (foreigner identification number) or municipal registration. Completing those procedures does not in any way substitute for the submission of Form 149.
Application process for the Beckham Law
Application to the Tax Agency
The process begins by submitting Form 149 to the Tax Agency. This is the official application form for the special inbound workers regime and must be accompanied by the documentation proving compliance with all the requirements established by the regulations.
Submission can be done electronically through the AEAT’s electronic office, using a digital certificate or with the intervention of an authorized representative (advisor or manager with powers from the taxpayer). As errors in completing the form can lead to delays or rejections, it is highly advisable to seek professional advice at this stage.
Required documentation
The documents that usually accompany Form 149 are the following:
- Employment contract or documentation proving the reason for the move to Spain.
- Document of registration with Spanish Social Security or the alternative social welfare fund.
- Tax residency certificate(s) issued by the authorities of the country or countries of residency during the five years prior to the move.
- Passport or NIE of the applicant.
- In the case of freelancers or entrepreneurs, additional documentation proving the nature of the activity and its connection with the move.
The more supporting documentation provided from the outset, the lower the probability that the Tax Agency will request subsequent clarifications that extend the process.
Deadlines and resolution
The Tax Agency has a deadline for resolving the application, although in practice timings may vary depending on the administration’s workload. A favorable resolution is notified electronically to the applicant’s enabled electronic address.
While the application is being processed, the payer or withholder must apply the fixed rate of 24% on employment income from the moment they know that the employee has opted for the regime. This implies communicating the application to the HR department or payer without delay, so they can adjust the withholding calculation from the start.

What happens after approval?
Once the regime is approved, the taxpayer is taxed under special conditions: a fixed rate of 24% on the first €600,000 of the taxable base and 47% for the excess. This represents very significant savings compared to the general income tax regime, where marginal rates can reach 47–54% depending on the region.
Additionally, during the period of application of the regime, the taxpayer is only taxed on income from Spanish sources. Income obtained abroad — dividends, rents, capital gains on assets outside Spain — is generally outside the scope of Spanish income tax. This characteristic is especially valuable for those who maintain assets or income flows in other countries.
Each year, the taxpayer must submit Form 151 (instead of Form 100 of the general regime) as the annual income tax return under the special regime. This form has its own characteristics and it’s worth knowing them well to avoid making errors in the return.
Common problems in the application
The most common — and most serious — problem is submitting the application outside the six-month deadline. This frequently occurs when the taxpayer was unaware of the existence of the regime upon arriving in Spain, or when they delayed seeking advice. In that case, the only option is to pay tax under the general regime for that entire fiscal year.
Another common problem is incomplete or poorly apostilled documentation. Tax residency certificates issued by foreign authorities must be correctly apostilled and, in some cases, translated into Spanish. Obtaining these documents can take weeks, making it essential to plan ahead with sufficient time.
There is also confusion about which income falls within the regime and which doesn’t. Some taxpayers assume that all their income is taxed at 24%, without considering that capital income or capital gains have a different treatment. An annual review of the tax situation with a specialized advisor is highly advisable throughout the application period of the regime.
