The year 2025 has started with a series of regulatory changes that should be on the radar, especially for those who develop their economic activity as freelancers or manage a company. Some of these measures come into force this year; others were already foreseen in previous years and are starting to be applied effectively. In addition, there are reforms still in the legislative development phase which, if approved, could substantially modify the current tax framework.
That is why, below, we offer you a summary of the main changes that have already been confirmed and those that should be closely followed throughout the year.
Tax Changes in Spain: Self-Employed Contribution Brackets in 2025
Index of contents
As of January, the contribution system for the self-employed has brought very significant changes:
- Reduction in low brackets: the self-employed with an income of less than 1,700 euros will have lower monthly quotas, with an annual reduction of between 80 and 428 euros, depending on the bracket.
- Increase for income above 1,700 euros: these will see an annual increase of between 272 and 970 euros, depending on the bracket.
Regularization of contributions in 2025
In addition, during the first four months of the year, the regularization of contributions corresponding to 2023 has been carried out, comparing the amount paid with the actual income declared:
- January-February: automatic refund in cases where contributions have been paid in excess of what was due.
- March-April: notification of the amount to be paid and deadline to pay the difference, in the event of underpayments.
This regularization will be repeated in successive years, so it is important to adjust the brackets correctly from the beginning of the fiscal year.
New Corporate Tax rates (Impuesto sobre Sociedades – IS)
In turn, as from fiscal year 2025, whose liquidation will be presented in 2026, reduced Corporate Income Tax (IS) rates will be applied for micro-companies and SMEs, according to Law 7/2024:
- For micro-companies with a turnover of less than 1 million euros: They will have a reduced rate of 21% for the first 50,000 euros of taxable base. In addition to 22 % for the rest of the base.
- For small and medium-sized companies with a turnover between 1 and 10 million euros: They will have a reduced rate of 24% instead of the usual 25%.
These measures seek to alleviate the tax burden on small businesses and facilitate their growth.
Increase in the Intergenerational Equity Mechanism (MEI), a Spanish public pension contribution
The MEI, applied since 2023 with the aim of strengthening the income of the public pension system, will rise again in 2025.
In other words, it would increase from 0.7% to 0.8% of the contribution base, both for employees and the self-employed.
This percentage is applied to social contributions and has a direct impact on companies’ labor costs.
Changes in the retirement age for the self-employed
From the beginning of the year, i.e. from January 1, 2025, the ordinary retirement age with 100% of the pension will be 65 years, provided that they have been able to contribute at least 38 years and 3 months. This represents an increase of three months compared to 2024.
However, one of the most important new features is that, if this minimum contribution period is not reached, the legal age is postponed to 66 years and 9 months. This is a change that especially affects long-term self-employed workers and forces them to review their retirement planning.
On the other hand, the option of early retirement is always left open for anyone who wishes to retire before that date. For this to be possible, a reduction in the percentage of the pension to be received would have to be made.
Mandatory electronic invoicing and Verifactu system
This year also marks a turning point in administrative digitalization, with the entry into force of Order HAC/1177/2024, which regulates the electronic invoicing system and the Verifactu model, which will allow invoicing programs to connect directly with the Tax Agency (AEAT).
In this way, the change implemented seeks to improve transparency and communication with the AEAT.
What requirements does Verifactu introduce?
- Incorporation of fingerprints and electronic signature to guarantee the integrity of invoices.
- Authentication by means of electronic certificate.
- Responsible declaration of the supplier of the invoicing software.
Although it was originally planned to be mandatory from July 2025, everything points to an extension that could extend the deadline until the end of the year or early 2026.
