On 17 June 2026, HMRC quietly published updated guidance that every CFO of a multinational enterprise operating in the UK should be reading this weekend. The Transfer Pricing and Profit Diversion Compliance Facility — the TP&PDCF — is not a rebranding exercise. It is a substantive expansion of HMRC’s voluntary disclosure mechanism that, combined with the new Unassessed Transfer Pricing Profits regime and the incoming International Controlled Transactions Schedule, signals the most significant shift in UK transfer pricing enforcement in a decade. If your group has cross-border related-party transactions that haven’t been reviewed recently, this is your window to act before HMRC acts for you.
What Just Changed and Why It Matters
The original Profit Diversion Compliance Facility (PDCF) was introduced in 2019 with a narrow mandate: give multinational enterprises (MNEs) using arrangements targeted by Diverted Profits Tax (DPT) an opportunity to come clean. Over seven years, it secured an additional £872 million in revenue and proved that the voluntary disclosure model works. HMRC got the tax. Taxpayers avoided full enquiries. Everyone moved on.
The 2026 update changes the game in two ways. First, it reflects the abolition of DPT under Finance Act 2026 and the introduction of the Unassessed Transfer Pricing Profits (UTPP) regime — effective for accounting periods beginning on or after 1 January 2026. Unlike DPT, which was a standalone punitive tax, UTPP is embedded directly within the corporation tax framework. HMRC no longer needs a separate legislative mechanism to chase diverted profits; the charge sits inside CT. That is a more efficient enforcement tool, and it should focus CFO minds accordingly.
Second — and this is the part that catches many groups off guard — the facility’s scope has been dramatically broadened. The TP&PDCF is no longer limited to outright profit diversion arrangements. It now covers all significant non-financial transfer pricing risks. That includes intra-group services, intellectual property arrangements, supply chain structuring, and permanent establishment profit attribution. If your transfer pricing policy hasn’t been benchmarked against the OECD Transfer Pricing Guidelines recently, or if your functional analysis doesn’t reflect how your business actually operates today (as opposed to how it was structured when the policy was written), you are potentially in scope.
The UTPP Regime: DPT’s More Dangerous Successor
CFOs who breathed a sigh of relief when DPT was repealed may be misreading the situation. DPT was a 25% deterrent tax applied via a separate charge notice — confrontational, slow, and reliant on a distinct legislative gateway. UTPP operates differently. It charges corporation tax on profits that should have been recognised under existing transfer pricing rules but weren’t. There is no separate notice, no separate rate. The charge integrates with the CT return, and the assessment window mirrors CT’s extended time limits where behaviour falls short of reasonable care.
As Deloitte’s TaxAtHand commentary notes, UTPP functions as a broader transfer pricing enforcement mechanism. HMRC can assess profits where conditions regarding tax mismatch and design intention are met — and those conditions are not narrowly drawn. Groups that previously concluded they were outside DPT’s scope because they lacked a specific “tax mismatch” or “contrived arrangement” structure should re-examine that position under UTPP’s framework, which is captured within INTM489100 onwards of the International Manual.
Who Should Be Looking at This — and Why Now
HMRC is explicit that the TP&PDCF is not for compliant groups. If you are confident your transfer pricing is correct and your CT position accurately reflects economic activity in the UK, you do not need to engage. But the honest question every CFO should ask is: how confident are we, really?
The facility is aimed at MNEs where one or more of the following is true:
- Cross-border arrangements that under-reward UK functions, assets, or risks relative to overseas entities taxed at lower rates.
- Transfer pricing policies based on a fact pattern that has since diverged from operational reality — common in fast-growing businesses where the functional profile shifts but the TP documentation doesn’t.
- Intra-group arrangements with over-reliance on contractual assumption of risk rather than substantive control functions actually located in the contracting entity.
- Benchmarking studies that are more than three years old or rely on comparables that don’t reflect current market conditions.
- Intra-group services arrangements where the UK is paying for services it cannot demonstrate it receives — or receiving payment for services that aren’t adequately documented.
- PE profit attribution issues where the UK permanent establishment’s contribution to value creation has not been properly reflected in returns.
Forvis Mazars’ analysis makes an important point: the broadened definition means many groups that would not previously have considered the PDCF may now fall within scope, even absent overt profit diversion indicators. That is a material change in the risk population. If your TP review was triggered only by DPT-style concerns, it may no longer be adequate.
The Window of Advantage — and How It Closes
The TP&PDCF’s key advantages over a formal HMRC enquiry are real but time-limited:
Unprompted penalty treatment. If you register before HMRC opens an investigation, your disclosure is treated as unprompted. Under HMRC’s penalty regime, unprompted disclosures attract materially lower penalties than prompted ones — often the difference between a 15% and a 70%+ penalty for careless behaviour, and between 30% and 100% for deliberate understatement. That saving can be significant on a six- or seven-figure adjustment.
Accelerated resolution. HMRC commits to responding to proposals within three months of submission. Compare that to the multi-year timescale of a full transfer pricing enquiry, which ties up management time, occupies your tax team, and creates uncertainty on your balance sheet provisions.
Control over evidence gathering. You decide who is interviewed, which comparables are used, how the analysis is presented. In an enquiry, HMRC drives the agenda. The TP&PDCF gives you the initiative — provided you maintain it with a rigorous, well-evidenced report.
No publication under Deliberate Defaulters. Where deliberate inaccuracies are disclosed, HMRC will not publish details of the entities involved — provided the disclosure is complete and accurate. Reputational protection matters, particularly for PE-backed groups where portfolio companies are subject to vendor due diligence.
The window closes the moment HMRC opens an enquiry. At that point, all of the above evaporates. You are in an adversarial process with a specialist team that has already formed a view. Simmons & Simmons note that HMRC is issuing a new round of TP&PDCF nudge letters to accompany the expanded facility launch. If you receive one, the clock is already running.
The ICTS: HMRC’s Next Enforcement Weapon Is Already Being Built
Even if you conclude the TP&PDCF is not immediately relevant to your group, there is a second timeline that every CFO with cross-border operations needs to understand: the International Controlled Transactions Schedule (ICTS).
For accounting periods commencing on or after 1 January 2027 — first filings expected in 2028 alongside the CT return — in-scope MNEs will be required to file granular, transaction-level data on all cross-border related-party transactions. BDO’s ICTS briefing sets out the scope: the nature and type of controlled transactions, the identity and jurisdiction of counterparties, the transfer pricing methodology applied, financial values, and key pricing framework elements. This is not CbCR at group level — it is transaction-level data filed with every CT return.
The strategic significance is this: HMRC will use ICTS data for automated, data-led risk profiling. For the first time, HMRC will have a structured, standardised dataset that allows it to compare transfer pricing approaches across industries, flag statistical outliers, and target enquiries with a precision it has never previously had. Inconsistencies between ICTS data, your TP documentation, and your actual CT return will be visible to HMRC’s risk systems before a human specialist ever opens the file.
The window between now and the first ICTS filing is not merely a compliance preparation period. It is the period during which the TP&PDCF remains available on favourable terms. Groups that have unresolved transfer pricing risks should consider whether to use the facility to clean up historic positions before ICTS data makes those positions self-evident to HMRC.
The Senior Accounting Officer Dimension
For UK CFOs of large businesses, transfer pricing compliance is not just a tax technical matter — it sits squarely within the Senior Accounting Officer (SAO) regime. The SAO is required to certify that the company has appropriate tax accounting arrangements in place. A transfer pricing policy that doesn’t reflect operational reality, or that hasn’t been updated to reflect business changes, is an SAO exposure. HMRC’s updated TP&PDCF guidance specifically flags inadequate TP documentation as a potential indicator of deficient accounting processes — language that maps directly onto SAO obligations.
If your TP documentation would not withstand scrutiny in an HMRC enquiry, it will not withstand scrutiny in an SAO review either. The two risks are the same risk.
Practical Steps for CFOs This Month
Given the combination of the TP&PDCF expansion, the UTPP regime, and the incoming ICTS, here is what I would be doing if I were sitting in the CFO chair of a mid-to-large MNE right now:
- Audit your existing TP documentation for staleness. When was the last functional analysis? Does it reflect the business as it operates today? Has the supply chain, intellectual property ownership, or key decision-making location shifted since the documentation was prepared?
- Map cross-border transactions against HMRC’s GfC7 common risk indicators. HMRC’s Guidelines for Compliance 7 sets out the arrangements HMRC considers highest risk. Run your transactions against that list. If any flag, you need to know before HMRC does.
- Identify any historic periods with potential exposure. The TP&PDCF requires disclosure of all relevant accounting periods within HMRC’s assessment window. For careless behaviour, that is typically four years; for deliberate behaviour, 20 years. Understand your exposure before you register.
- Assess ICTS readiness. Do your internal systems capture transaction-level data at the granularity the ICTS will require? If not, the data architecture work starts now, not in 2026.
- Consider APA or TP&PDCF for forward certainty. If the uncertainty is about future arrangements rather than historic ones, an Advance Pricing Agreement may be more appropriate than the TP&PDCF. The two are complementary, not mutually exclusive — groups can use the TP&PDCF to resolve historic periods and then pursue an APA for certainty going forward.
- Engage your advisers before HMRC engages you. KPMG’s transfer pricing commentary and Baker McKenzie’s ICTS briefing are worth reading alongside HMRC’s own guidance. The regulatory direction is clear: HMRC is building the data infrastructure to identify transfer pricing risks systematically. The advisory community’s role shifts from reactive to proactive.
The Broader Signal
HMRC has been telegraphing its transfer pricing strategy for the past two years: the GfC7 compliance guidelines in September 2024, the Finance Act 2026 UTPP provisions, the TP&PDCF expansion in June 2026, and the ICTS coming in January 2027. These are not isolated policy decisions. They form a coherent, progressive enforcement architecture — better data, more integrated charges, a voluntary disclosure pathway that is genuinely advantageous early on and punitive if you wait.
The £872 million the original PDCF yielded came from groups that chose to come forward. The question is whether the groups that didn’t — those that concluded their arrangements were defensible, or that HMRC wouldn’t get to them — will find the new TP&PDCF and the ICTS data combination has changed that calculus. Based on everything HMRC has published this year, the answer is yes.
For PE-backed businesses in particular, the timeline matters. Transfer pricing exposure that sits unresolved on a balance sheet — as an uncertain tax position under FRS 102 or IFRS — affects deal valuations, completion accounts, and W&I insurance coverage. Cleaning up a position through the TP&PDCF before a sale process is materially better than surfacing it as an unquantified liability during vendor due diligence.
