Royal Decree-Law 3/2026: tax changes, urban planning and housing affecting your business

Key data

Developers, builders and companies with real estate projects have normative changes on the table that are already in force since March 24, 2026, although the Royal Decree-Law 3/2026 was published in the BOE on May 14, 2026. This difference in dates is relevant: the measures are applicable from weeks ago, and any operation or procedure carried out since late March is already under this new framework.

The decree groups four blocks of measures under the same urgency: the situation of budget extension, which prevents the administration from acting with ordinary mechanisms. The result is a normative package that touches taxation, urban planning procedures, housing and public personnel management.

What does this regulation establish?

Royal Decree-Law 3/2026 is structured in four major blocks of measures:

The context of budget extension is key to understanding why the royal decree-law route is used. Without approved budgets, the administration cannot execute certain ordinary actions, which forces it to enable urgent measures to unblock procedures and adjust taxation to the reality of fiscal year 2026.

In the tax field, modifications may involve changes in taxes of the autonomous community or in taxes transferred by the State (such as personal income tax, Inheritance Tax or Property Transfer Tax), which are those that most impact real estate operations and the tax burden of companies and individuals.

Economic and operational impact

For companies, the impact is concentrated in two main vectors:

1. Tax cost of real estate operations. If modifications affect transferred taxes such as Property Transfer Tax or Documented Legal Acts Tax, any purchase, financing or property transfer carried out since March 24, 2026 may be subject to different rates or conditions. Companies with ongoing operations must verify whether the tax conditions of their transactions have changed.

2. Streamlining of licenses and urban planning procedures. The reduction of administrative deadlines in the processing of licenses has a direct economic impact: less waiting time equals lower maintenance costs for land, lower risk of project deviation and greater predictability in construction schedules. For developers with projects in process, this measure can mean real savings in financing costs.

3. Simplification of procedures. Administrative streamlining reduces the bureaucratic burden for companies that frequently interact with the administration, especially in sectors such as construction, real estate development or any activity that requires authorizations or licenses.

Who does it affect?

• Real estate developers: affected by changes in license procedures and by possible modifications in taxes linked to transfers and documented legal acts.
• Construction companies: impact on the streamlining of urban planning procedures and on the deadlines for obtaining permits.
• Taxpayers of own or transferred taxes: any company or individual subject to taxes that have been modified by this royal decree-law.
• Real estate investors: the tax conditions for acquisition or transfer of real estate may have changed since March 24, 2026.
• Public employees: affected by personnel measures approved in the context of budget extension.
• Tax and legal advisors: must update their knowledge of modified taxes to correctly advise their clients on operations carried out since entry into force.

Practical example

A real estate development company that has a major construction license in process since early 2026 can directly benefit from the urban planning procedure streamlining measures introduced by this royal decree-law. If the new administrative deadlines reduce the resolution time, the company can advance the start of works, reduce the land financing period and improve the project's bottom line.

At the same time, if the developer plans the transfer of real estate units or the formalization of new construction deeds since March 24, 2026, it must verify with its tax advisor whether the applicable transferred taxes (Property Transfer Tax, Documented Legal Acts Tax) have been modified by this royal decree-law, as the tax conditions of those operations may have changed compared to those in force before that date.

This double impact—operational streamlining and possible tax variation—makes the review of the royal decree-law a priority for any company with active real estate projects in 2026.

What should companies do now?

1. Identify if they operate in the affected areas: review whether the company has activity in the construction, real estate development sectors or if it is a taxpayer of own or transferred taxes that may have been modified.
2. Verify the retroactive tax impact from March 24: given that entry into force is prior to publication in the BOE, any operation carried out from that date may be subject to the new tax framework. Review real estate transactions, deeds and tax settlements carried out from that date.
3. Consult the status of licenses and urban planning procedures in progress: if there are open license files, verify whether the new streamlining measures apply to them and whether administrative deadlines have changed.
4. Update tax planning for real estate projects: if there are purchase, financing or transfer operations planned for 2026, recalculate the tax burden under the new regulatory framework.
5. Inform the financial and legal team: ensure that CFO, tax advisors and legal teams know about the changes and apply them correctly in contracts, settlements and financial projections.
