The Tax Office Begins Billing EDP's Douro Dam Sale, Starting With €12.2 Million of a €335 Million Claim
The Autoridade Tributaria has issued its first assessment on the 2020 sale of six dams to the Movhera consortium, with the balance expected in September. EDP disputes both the tax framework and the sums, and will not pay until the courts rule.
After nearly six years of argument, Portugal's tax authority has started sending bills. The Autoridade Tributária (AT) has issued its first assessment on the 2020 sale of six hydroelectric dams by EDP, a stamp-duty demand of €12.2 million served on entities involved in the transaction. It is the opening instalment of a claim worth about €335 million, and the rest is expected in September.
The deal in question closed in December 2020, when EDP sold six dams to the Movhera consortium, which includes the French utility Engie, for €2.173 billion. The structure used to complete it, and the tax treatment that followed, has been contested ever since.
What the state says it is owed
According to the Ministério Público investigation completed last November, the AT must collect a total of €335.2 million. It breaks down into roughly €114.6 million in corporate income tax (IRC), €120.8 million in stamp duty split across two assessments, of which the €12.2 million now issued is the second, and €99.6 million in property transfer tax (IMT).
EDP's position has not moved. In May the company said it did not accept either the tax framework the AT had applied or the amounts calculated, and that it would not pay until the courts had ruled. That was the position it set out when the AT closed its inspection report in April, and it is the position it holds today.
Why the clock mattered
The reason this has become a story about dates rather than principles is prescription. Tax claims expire, and this one was approaching its limit. We reported earlier this month that the €335 million risked lapsing in October if the fisco failed to act, a deadline that turned an accounting dispute into a test of whether the state can collect from its largest companies at all.
Issuing the assessments stops that clock. It does not end the fight: EDP will contest the liquidations, the case moves to the tax courts, and any money actually reaching the Treasury is years away. But the difference between a claim that has been formally raised and one that quietly expires is the difference between a legal argument and a write-off.
The councils still waiting
There is a local dimension that has been overshadowed by the headline number. The IMT component is municipal revenue, owed to the councils where the dams sit. As we reported when the bill came due earlier in August, several Trás-os-Montes municipalities have been waiting five years for a share of transfer tax on assets in their own territory, in a region where a nine-figure windfall would be transformative.
The dams themselves, on the Douro Internacional and the Sabor, remain in Movhera's hands and generating regardless. What is being fought over is who pays for the paperwork of moving them, a question that arrives as the AT takes an increasingly assertive line with the energy sector generally, including a reclassification of wind and solar parks that could double their municipal tax bills.
For a tax authority that changed leadership at the start of this month, it is an early and conspicuous test.
