Tax Consolidation Advisory for Corporate Groups
Unsure whether tax consolidation is right for your group?
- Concerned about making formal mistakes that could invalidate the regime?
- Not sure your group’s structure qualifies for consolidation?
- Worried poor management could lead to penalties or the loss of tax benefits?
- Frustrated with a lack of clear answers from your current advisor?
- Has the Spanish Tax Agency (AEAT) raised concerns about your consolidated tax status?
Managing this regime without specialist support is risky. It can cost your business time, money, and credibility.
At GCO, we’ve been guiding corporate groups through tax consolidation for years — ensuring compliance, maximising benefits, and mitigating risks every step of the way.

Tax Consolidation Advisory for Corporate Groups
"Is it really worth entering such a complex tax regime?"
A fair question.
Tax consolidation isn’t mandatory — and yes, it does come with legal and technical complexity. But when properly implemented, it offers real value: significant tax savings, stronger financial oversight, and reduced compliance risk.
At GCO, we help you assess the business case with data — not guesswork. If the regime is viable for your group, we handle the full implementation and compliance process with precision and clarity.

Frequently Asked Questions
Answers to your key questions about tax consolidation for corporate groups
What kind of companies can apply the tax consolidation regime?
Companies must have a minimum 75% direct holding relationship and meet the requirements to form a consolidated tax group under Spanish tax law.
What happens if the group fails to meet the requirements?
The group automatically loses the regime and must revert to individual taxation — potentially retroactively — with interest and penalties. That’s why we proactively monitor your compliance year-round.
Can we opt into the regime at any time?
No. The regime must be applied from the start of the financial year and formally communicated to the AEAT. Planning ahead is essential.
Is it compatible with other tax regimes?
Yes, but careful coordination is required. Some deductions and incentives may be affected. We assess your full tax landscape to avoid conflicts and preserve all available advantages.
What are the risks of applying the regime without expert support?
Common pitfalls include invalid group setup, incorrect filings (e.g., Model 220), and failure to comply with formal requirements — all of which can result in loss of benefits, audits, and penalties.
After TAX consolidation setup, what?
Do you need more than tax consolidation?
Tax consolidation often goes hand in hand with broader structural, legal, and financial decisions. At GCO, we offer advisory services that support your group beyond tax.
Corporate restructuring
We plan and implement mergers, demergers, and other structural changes to optimise your group before or after entering the regime.
Financial reporting & consolidation
We consolidate group-level financials to improve control, transparency, and decision-making — aligned with tax consolidation requirements.

We help coordinate the tax position of subsidiaries abroad or foreign entities consolidating in Spain, ensuring cross-border compliance.
