The Spanish tax landscape for 2026 brings significant changes that every growing business needs to understand and anticipate. From modifications to tax rates to new incentives for internationalization, tax planning is more than ever a key strategic tool.
Key changes for the 2026 fiscal year
The tax reform approved in late 2025 introduces relevant adjustments to Corporate Income Tax. Companies with turnover below ten million euros will benefit from an expanded reduced rate, provided they meet certain requirements regarding job creation and profit reinvestment. Additionally, deductions for research, development and technological innovation are strengthened, with more generous percentages for projects incorporating artificial intelligence and sustainable technologies.
Impact on expanding businesses
For companies in a growth phase, tax planning takes on an especially critical dimension. Expansion into new markets, hiring international talent and investing in productive assets generate fiscal opportunities that, when well managed, can result in significant savings. However, they also increase the complexity of regulatory compliance.
It is essential to review the corporate structure and cash flows to ensure that the tax burden is optimized within the legal framework. Coordination between domestic and international taxation is particularly relevant in cross-border operations, where double taxation treaties and European directives offer tax efficiency mechanisms that should not be overlooked.
Recommended strategies
At BM Consulting, we recommend our clients adopt a proactive approach. This involves conducting a comprehensive tax review before the end of the first quarter, identifying applicable deductions and allowances, and establishing a tax obligations calendar to avoid surprises. Digitizing accounting processes and integrating real-time tax reporting tools are investments that pay for themselves quickly.
Looking ahead
The tax environment will continue to evolve with the progressive implementation of the OECD Pillar Two framework and new fiscal transparency obligations. Companies that integrate tax planning as part of their corporate strategy will be better positioned to grow sustainably and competitively.
At BM Consulting, our tax team works closely with clients to turn regulatory complexity into competitive advantage. If you need guidance on how these changes affect your business, do not hesitate to contact us.
