Spain’s tax agency has confirmed a major overhaul of financial reporting rules that will come into force on January 1, 2026.

The reforms are among the most wide-ranging in recent years and will require banks, payment providers and digital finance platforms to share far more information with Hacienda.

The taxman will want to know more than ever about how people and businesses move their money, allegedly to crack down on illegal activity.

Below are the most important updates.

More accounts under scrutiny

Until now, reporting duties focused mainly on traditional bank accounts and large transactions.

From 2026, that net widens significantly.

The new rules will cover:

• Payment accounts
• Physical and virtual cards
• Mobile payment platforms (including Bizum)
• Digital financial services

These will be monitored even if they don’t generate interest or direct financial returns.

Those who trade in cryptocurrency or use Bizum for their businesses must ensure they are declaring everything correctly to avoid raising alarms with the tax authorities.

Monthly reporting for freelancers and businesses

The most significant change for professionals and companies is the end of the long-standing €3,000 threshold.

From January 2026, all card and electronic payments must be reported monthly, and there is no minimum threshold.

This includes payments through card terminals (TPV), mobile apps and growing numbers of online payment platforms.

The aim is to let the tax agency cross-check real-time payment data against declared invoices and income.

For the non self-employed: a new €25,000 annual card-spend threshold

Private citizens will also see changes, though less sweeping.

Financial institutions will have to report annual card activity when a user’s total operations exceed €25,000 across the year.

The Hacienda says the goal is to detect unusually high financial activity, not to monitor people with ordinary spending habits.

Bizum between friends still exempt

Payments between individuals via Bizum or similar apps will not be reported, as long as they are personal and not linked to economic activity

If patterns suggest business use, the transactions will fall under the new reporting rules.

That’s why it is very important to clearly label what the transfers are for.

Why the reform is happening

Hacienda argues the update is essential to track digital money more effectively and strengthen the fight against tax fraud.

The shift recognises that much of Spain’s economic activity, from freelancing to everyday payments, has moved away from cash and traditional accounts.

Banks, payment platforms and professionals will spend the coming months adapting their systems to comply with the new requirements.

For most citizens, the change will be barely visible, though certain types of card spending and digital transactions will now leave a clearer trace in the tax agency’s records.
