Diverted Profits Tax for multinationals
Guide to Diverted Profits Tax (DPT) for multinational businesses operating in the UK. Understand the 31% tax rate, two charging scenarios (avoided PE and mismatch arrangements), exemption thresholds, notification requirements, and the 2026 reform integrating DPT into Corporation Tax.
Diverted Profits Tax (DPT) - often called the 'Google Tax' - is a punitive tax targeting multinational enterprises that artificially divert profits away from the UK. If your business has significant UK operations but routes profits through low-tax jurisdictions using contrived arrangements, you may be liable for DPT at 31% - deliberately set above the standard Corporation Tax rate.
DPT was introduced by the Finance Act 2015 to counter aggressive tax planning by multinationals. Unlike Corporation Tax, DPT is not self-assessed - HMRC issues charging notices after investigating potentially liable arrangements.
Who needs to know about DPT?
DPT primarily affects:
- UK subsidiaries of foreign multinationals with transactions involving connected overseas entities
- Foreign companies with significant UK sales that avoid establishing a UK taxable presence
- UK companies entering arrangements with low-substance foreign affiliates
- Groups using intellectual property holding structures in low-tax jurisdictions
DPT does not apply to smaller businesses - exemption thresholds exclude companies with limited UK activity from the charge.
The two DPT charging scenarios
DPT can apply in two distinct circumstances. Understanding which scenario might affect your business is essential for compliance planning.
Notification requirements
If you believe DPT may apply to any arrangements in your accounting period, you have a statutory obligation to notify HMRC. Failure to notify can result in significant penalties.
The HMRC charging process
Unlike Corporation Tax, you cannot self-assess DPT liability. Instead, HMRC investigates and issues charging notices through a formal process. You have the right to make representations before any charge is finalised.
-
Assess whether DPT scenarios apply
Review your group structure and inter-company arrangements against the two DPT scenarios. For avoided PE, consider whether foreign group companies have significant UK sales without a UK taxable presence. For mismatch arrangements, assess whether transactions with connected entities have sufficient economic substance.
-
Check against exemption thresholds
Calculate your UK-related sales revenue (for avoided PE) and UK-related expenses with connected entities (for mismatch). If below £10m sales and £1m expenses respectively, document this position and monitor for changes.
-
Review economic substance of arrangements
For any potentially in-scope arrangements, ensure foreign entities have genuine economic substance - appropriate staff, decision-making capability, and functions commensurate with the profits allocated to them.
-
Notify HMRC if required
Within 12 months of your accounting period end, notify HMRC if you believe DPT may apply. Notification should be in writing to the Counter-Avoidance Directorate with details of arrangements, parties, and relevant periods.
-
Respond to preliminary notices
If you receive a preliminary notice from HMRC, you have 30 days to make representations. Gather evidence of commercial rationale and economic substance. Engage tax advisers experienced in DPT matters.

Plan for the 2026 reform
DPT is being integrated into Corporation Tax from 1 January 2026. Review how this reform will affect your compliance processes and transfer pricing documentation.
Relationship with Corporation Tax
DPT is designed as an alternative to Corporation Tax for diverted profits, not an additional charge on the same profits. Key interactions:
- No double taxation: If DPT is charged on profits, HMRC may allow a corresponding CT adjustment to avoid taxing the same profits twice
- Higher rate: The 31% DPT rate exceeds the 25% main CT rate, creating a deterrent effect
- Different process: CT is self-assessed; DPT is charged by HMRC following investigation
- Payment timing: DPT must be paid within 30 days of a charging notice, even if disputed - unlike CT which can be deferred pending appeal in some circumstances
2026 reform - DPT integration into Corporation Tax
From 1 January 2026, DPT is being reformed and integrated into the Corporation Tax framework. This means:
- Transfer pricing mechanism: The existing transfer pricing rules will be strengthened to achieve similar outcomes to DPT
- 31% rate retained: Unassessed transfer pricing profits will be taxed at 31% - maintaining the punitive differential
- Self-assessment: The reformed rules will likely require companies to self-assess liability, rather than waiting for HMRC charging notices
- Simplified compliance: Integration should reduce administrative complexity of having separate DPT and CT regimes
Planning point: Review your transfer pricing documentation and policies before 2026 to ensure they meet the enhanced requirements of the integrated regime.
Practical compliance for multinational businesses
Annual review process:
- Include DPT assessment in your annual tax compliance calendar
- Review all significant inter-company transactions for substance and rationale
- Document the commercial purposes of arrangements - not just tax efficiency
- Ensure transfer pricing documentation supports arm's length pricing
- Monitor UK activity against exemption thresholds
Red flags that attract HMRC attention:
- High UK sales but minimal UK taxable profit
- IP held in low-tax jurisdictions with limited local staff
- Commissionaire or limited risk distributor arrangements
- Significant royalty or service fee payments to low-substance affiliates
- Arrangements restructured shortly before DPT introduction (April 2015)
Documentation to maintain:
- Transfer pricing reports supporting inter-company pricing
- Evidence of commercial rationale for group structure
- Records of staff functions and decision-making in each entity
- Board minutes evidencing genuine management in relevant jurisdictions
- Contracts and functional analyses for inter-company arrangements
