In 2026, Tax authorities have announced the sending of millions of notices to taxpayers, with a special focus on income from property rentals.

There is increasing control, more transparency and greater professionalisation in property management.

For those who own a rental property or are considering making it profitable, this reinforces a clear idea: renting remains an attractive option, but it is important to manage it correctly from the start.

Who these tax notices affect

The notices focus on several groups, but one of the most relevant is property owners who rent out homes.

Specifically, a significant number of notifications will be related to rentals and possible discrepancies in income declarations.

This includes both long-term rentals and tourist rentals managed through platforms.

Why tax control is increasing

The increase in control is not accidental. The Tax Agency now has access to more data thanks to information sharing with digital platforms and public bodies.

In practice, this means that the rental market is moving towards a more transparent and structured environment.

For real estate agencies and for owners who operate correctly, this helps differentiate well-managed operations and builds more market confidence.

What this means if you have a rental property

For an owner, the message is clear: renting remains a profitable option, but it must be properly managed.

In many cases, these notices act as informational alerts to review declarations and correct possible errors.

Owners who manage their property well can rent with more security, more control and less uncertainty.

How this affects Costa Blanca and Costa Cálida

In areas such as Torrevieja, Pilar de la Horadada, Orihuela Costa or San Pedro del Pinatar, where rentals are very important, these measures have a direct impact.

Many owners combine holiday rentals and long-term rentals, and demand remains strong. However, the need to properly manage income is increasing.

This does not reduce interest in renting. On the contrary, it reinforces the importance of professional management and makes the market more serious, more transparent and more secure for owners and tenants.

Is it a problem or an opportunity

For those who have not regularised their situation, it may require adjustment. But for those who work properly, it is an opportunity.

A more controlled market generates more transparency and confidence. This benefits owners who do things correctly, as their properties compete under better conditions.

How it affects property owners

For property owners in Costa Blanca South and Costa Cálida, this does not reduce the appeal of renting. On the contrary, it reinforces the importance of doing things properly and relying on professionals who understand the market.
