Bahrain has taken another concrete step in implementing the global minimum tax framework. In January 2026, the National Bureau for Revenue (NBR) activated the Domestic Minimum Top-Up Tax (DMTT) annual return on its online portal—marking the start of formal compliance under Pillar Two–style rules in the Kingdom.
For multinational enterprise (MNE) groups, this is not just a procedural update. It directly affects Transfer Pricing outcomes, effective tax rate calculations, and compliance planning over the next 18 months.
What Has Changed: DMTT Annual Return Is Now Available
The NBR has enabled the DMTT annual return functionality, allowing in-scope groups to begin preparing their filings.
Who Is Affected?
MNE groups that:
- Meet the €750 million consolidated revenue threshold
- Have met that threshold in at least two of the four preceding fiscal years
- Are subject to Bahrain’s DMTT regime
Before accessing the return, groups must submit a revenue test notification confirming threshold eligibility.
Key Filing Timeline to Note
For groups with a 31 December 2025 year-end:
- DMTT filing deadline: 30 June 2027
- This reflects the 18-month transitional filing period from the end of the relevant fiscal year
While the deadline may appear distant, the data requirements are extensive, and much of the underlying information ties directly to Transfer Pricing policies and results.
Why This Matters for Transfer Pricing in Bahrain
DMTT does not replace Transfer Pricing—but it amplifies its importance.
Here’s why:
- Transfer Pricing outcomes directly influence the effective tax rate (ETR) used in DMTT calculations
- Low-margin or routine entities may inadvertently trigger top-up tax exposure
- Year-end true-ups and pricing adjustments must align with minimum tax mechanics
- Inconsistent pricing can create misalignment between income tax and DMTT positions
- In short: pricing, profit allocation, and minimum tax are now inseparable.
What Multinational Groups Should Be Doing Now
Even with an extended deadline, early action is critical. MNEs operating in or through Bahrain should:
- Confirm whether the €750 million revenue test is met
- Submit the revenue test notification to unlock portal access
- Review Transfer Pricing models for Pillar Two and DMTT alignment
- Assess whether current margins could lead to top-up tax
- Begin mapping required data well ahead of filing
Waiting until 2027 to act will significantly increase compliance and audit risk.
