Global Minimum Tax Filings Begin as Ten States Face Legal Action

Dublin: In the offices where Europe’s largest companies file their accounts, tax directors have spent the spring wrestling with a return no one has ever submitted before. The bloc’s minimum tax rules have reached their first hard deadline, and the paperwork is finally due.

Multinational groups faced a 30 June deadline to file their first top-up tax information return under the EU’s Pillar Two directive, the law that guarantees large companies pay an effective rate of at least 15 percent wherever they book profits. The return turns a global political bargain into concrete filings, and it lands on finance teams as a genuinely new obligation rather than a tweak to an old one.

The reporting machinery rests on a directive known as DAC9, which lets tax authorities share the top-up information across borders through a standard template. Member states had to write DAC9 into national law by the end of 2025. Most did. Ten did not, and in January the Commission opened infringement procedures against the laggards, warning that a shared system fails if even a handful of capitals leave gaps.

Companies complain that the rules demand vast amounts of data for a tax that many will never actually owe. Supporters answer that the reporting itself is the point, because it exposes where profits land and closes the arbitrage that let firms shift earnings to near-zero jurisdictions. Ireland, long a magnet for corporate headquarters, now applies the same floor as everyone else.

Brussels has also moved to lighten the load. In late June the Commission published a tax simplification package that would consolidate the tangle of administrative-cooperation directives, DAC1 through DAC9, into a single instrument and trim duplicated reporting. The Commission sets out that proposal here, and explains the cooperation framework here.

The tension runs through the whole project. Governments want the revenue and the fairness that a global floor promises, yet they also fear driving mobile companies toward friendlier shores outside the Union. Every extra form sharpens the complaint that Europe taxes ambition as much as profit.

For now, the filings mark a milestone that seemed distant when finance ministers first signed up. The minimum tax has stopped being a communique and started being a return, stamped and submitted, with auditors and infringement letters to enforce it.
