At the start of each year, it is common for a certain level of tax uncertainty to arise. What tax changes does the new year bring? Which obligations should be taken into account? Will any of them affect my business during the year? In 2026, although no major structural tax reform has been approved, there are a number of official tax and fiscal updates that are worth knowing and considering in order to avoid unexpected issues.
This article summarises the main tax changes in Spain for 2026, affecting IRPF, VAT, Corporate Tax and the new obligations for businesses and self-employed workers.
Main tax developments in Spain expected for 2026 (IRPF, VAT, Corporate Tax)
Index of contents
The tax updates for 2026 stem from several different provisions approved at the end of 2025 and the beginning of 2026. These include Royal Decree-Law 16/2025 of 23 December, as well as regulatory developments and administrative criteria already published by the Spanish Tax Agency.
The main themes for the year are:
- Strengthening of reporting obligations, particularly in relation to electronic payments.
- Extension of tax incentives linked to energy efficiency and sustainable mobility until 31 December 2026.
- Certain changes to deadlines and tax regime options, mainly affecting self-employed professionals and small businesses.
This does not involve a general increase in taxes, but it does reflect a new environment with greater formal compliance requirements and a stronger focus on consistency between reported information and data available to the tax authorities.
Personal Income Tax (IRPF) changes in Spain in 2026
Employment income – IRPF rules in 2026
In 2026, no general changes have been approved to the tax brackets or state tax rates applicable to Personal Income Tax. However, the Spanish Tax Agency has intensified its scrutiny of certain items that frequently give rise to issues, such as benefits in kind, employee benefits and flexible remuneration schemes.
As a result, companies need to review the correct tax treatment of these items and ensure they are properly reflected in payroll and in the corresponding reporting forms, in order to avoid discrepancies that could lead to subsequent tax adjustments.
Savings and investment income – IRPF control 2026
The taxation of savings remains unchanged in terms of tax rates, but controls over capital gains and investment income have been strengthened, particularly in relation to digital assets. The Spanish Tax Agency continues to develop and apply reporting mechanisms for cryptocurrency transactions, in line with existing legislation and European commitments.
As a consequence, taxpayers are required to keep accurate records of transactions, including dates and acquisition and disposal values, as any gain or loss must be correctly reported in Personal Income Tax.
Savings and investment income – IRPF control 2026
The exemption provided for in Article 7.p of the Personal Income Tax Law, which applies to employment income earned for work carried out abroad, remains fully in force in 2026. However, the tax authorities are demanding increasingly robust evidence that the applicable requirements are met, particularly regarding the number of days actually worked outside Spain and the nature of the assignment.
Alongside this exemption, other common exemptions, such as those applicable to certain compensation payments, should be reviewed with particular care to avoid potential tax contingencies.
VAT updates in Spain for 2026 and new reporting obligations
No general changes have been approved in 2026 to VAT rates applicable to goods or services. However, reporting and control obligations have been significantly reinforced.
From this year onwards, banks and financial institutions are required to provide the Spanish Tax Agency with monthly aggregated information on payments received by self-employed professionals and companies through electronic payment methods such as Bizum and other digital systems, provided these payments are linked to an economic activity. This information includes, among other aspects:
- Identification of the payment recipient.
- Aggregated amounts received through electronic payment methods.
- Monthly frequency of the information submitted to the tax authorities.
This obligation does not affect payments between private individuals, but it significantly increases the authorities’ ability to cross-check data and verify that income reported for VAT and Personal Income Tax purposes matches the amounts received.
VAT updates in Spain for 2026 and new reporting obligations
Corporate Income Tax maintains its general structure in 2026, but consolidates measures approved in previous years.
One of the most relevant aspects is the gradual reduction of the tax rate for micro-companies, defined as entities with turnover below one million euros. In 2026, these companies apply a reduced rate to the first tranche of taxable income, which may result in significant tax savings if properly planned.
In addition, tax incentives linked to sustainable mobility, energy efficiency and innovation remain in place, along with more favourable depreciation regimes where the legal requirements are met, including:
- Incentives related to investments in energy efficiency.
- Tax benefits associated with sustainable mobility.
- Deductions and favourable depreciation regimes for certain assets.
For other companies, controls over related-party transactions and the offsetting of tax loss carryforwards have been reinforced.
Tax changes for self-employed workers in Spain in 2026
Among the most relevant tax changes affecting self-employed professionals in 2026 is the extension of the deadline to opt out of or re-enter the objective assessment system (modules) and the simplified VAT regime. This deadline has been exceptionally extended to 31 January 2026, allowing taxpayers to:
- Assess more carefully which tax regime is most appropriate.
- Compare the tax impact of the modules system versus direct assessment.
- Plan the year with greater certainty.
In addition, adaptation to the new CNAE 2025 classification becomes mandatory in 2026 and must be reported to the Social Security authorities. Although this is an administrative change, it can affect activity classification, contribution bases and certain labour and tax obligations.
All of this takes place in a context of increased monitoring of income, particularly income received through digital payment channels.
Electronic invoicing in Spain: what changes in 2026
Electronic invoicing continues to advance in 2026, although the obligation to implement the most advanced verifiable invoicing systems (VeriFactu) was officially postponed to 2027 at the end of last year.
Under the regulations derived from Royal Decree 1007/2023 and its subsequent amendments, the currently expected implementation dates are:
- 1 January 2027 for companies with turnover below 6 million euros.
- 1 July 2027 for other companies and self-employed professionals.
Although these systems are not mandatory in 2026, the year is considered key for preparing internal processes, adapting tools and reviewing invoicing management to transition to the new framework smoothly.

Other changes to be considered in 2026 include the update of the coefficients applicable to the Municipal Capital Gains Tax (tax on the increase in value of urban land), which affects property transfers.
In addition, certain reporting obligations and the penalty regime have been reinforced, particularly in cases of repeated non-compliance or significant discrepancies between reported data and information available to the tax authorities.
Other relevant tax changes in Spain for 2026
The 2026 tax calendar maintains its usual structure, but it is worth recalling some key dates:
- By 20 January 2026: filing of returns corresponding to the fourth quarter of 2025 (Forms 111, 115, 123, 210, among others).
- By 30 January 2026: payment of certain instalments and adjustments.
These dates are complemented by the usual monthly and quarterly obligations, as well as new reporting requirements that call for more precise tax planning.
