What is the Tax Simplification Omnibus?
On 24 June 2026, the European Commission proposed a sweeping Tax Simplification Package, including two directive proposals: the Direct Taxation Omnibus and the Recast of the Directive on Administrative Cooperation (DAC). These aim to modernize the EU direct tax framework and cut compliance costs dramatically. (taxation-customs.ec.europa.eu)
Pillar 2 & CFC Rule Reforms: What’s Changing
Here are the concrete changes affecting global minimum tax (Pillar 2) and CFC regimes:
-
Streamlined Reporting for Pillar 2: Companies already subject to a Qualified Domestic Minimum Top-up Tax (QDMTT) will see reduced reporting obligations under the DAC recast. Nearly 3,000 multinational enterprise (MNE) groups stand to benefit from lower compliance burdens. (taxation-customs.ec.europa.eu)
-
CFC Rules Harmonization: The Omnibus aims to reduce fragmentation by aligning national Controlled Foreign Company regimes with Pillar 2 requirements. Differences in how CFC income is taxed or excluded will be narrowed, to lessen overlapping compliance. (taxation-customs.ec.europa.eu)
-
Updated DAC Reporting Thresholds: Reporting thresholds under DAC7 (for sale-of-goods activity via platforms) will be increased (e.g. threshold raised to €3,000), and certain hallmarks in DAC6 will be refined or removed. (taxation-customs.ec.europa.eu)
Implications for Businesses
These changes will matter, especially if you run an MNE with cross-border operations:
| Situation | What Changes | What to Do Now |
|---|---|---|
| Already under Pillar 2 / QDMTT regimes | Less reporting under DAC; clearer rules for CFC regimes | Review your Pillar 2 compliance structure to see if you already qualify for reduced DAC obligations and ensure your CFC setup matches harmonized standards. |
| Small-to-medium-sized enterprises relying on platforms | Possibly fewer DAC7 reports if activity is low or thresholds raised | Check if your platform-based sales trigger DAC7; document revenue to avoid surprise liabilities. |
| Entities using life insurance products or other categories under DAC1 | Some reporting categories might be removed | Keep abreast of DAC1 changes; ensure necessary data is in place for categories that stay. |
Actionable Steps Toward Compliance
- Audit your global structure against Pillar 2 and current CFC regimes. Identify overlaps and gaps.
- Track implementation timelines: Directives must be adopted by Member States; national laws will follow. Ensure deadlines are met.
- Upgrade internal data systems: TIN verification, consolidated reporting, and data collection need to be stronger.
- Engage with advisors: Advisory firms (KPMG, EY, Deloitte, PwC) are raising toolkits and guidance to help businesses adapt.
Example Scenario
Imagine an EU company with subsidiaries in low-tax jurisdictions. Under current rules, it's filing multiple disclosures under DAC6/CFC rules and Pillar 2. Under the new Omnibus:
- If a QDMTT applies locally, the company could be exempted from some DAC6 reports.
- CFC rules will be more consistent, reducing complexity of determining what counts as “control” or what income is “at risk.”
- Overall compliance costs could drop by millions in legal, accounting and data-systems work over several years.
Bottom line: The Omnibus simplifies Pillar 2 and CFC compliance significantly. But it’s not live yet. Businesses should prep now to reap benefits and avoid surprises.
