On 10 September 2026 HMRC published Guidelines for Compliance GfC20 — Help with VAT on fund management services. It is not a soft “think piece.” It is HMRC’s recommended method for deciding whether outsourced fund-management services are a single supply or multiple supplies — and that classification decides whether the whole package is exempt under Items 9 and 10 of Group 5, Schedule 9 to the Value Added Tax Act 1994, or standard-rated at 20%.
If you sit on a PE holdco board, run an authorised fund manager, buy Aladdin-style platforms, negotiate MSAs with administrators, or sign off partial-exemption recoveries for an asset-management VAT group, treat GfC20 as a control note. The commercial habit of “one master contract, one invoice, split the fee by AUM” is exactly the pattern HMRC is testing.
Industry coverage is already live via Bloomberg Tax’s note on the guidance. Read GfC20 alongside the VAT Finance manual on special investment funds, the meaning of “management” at VATFIN5350, VAT Notice 701/49 (finance), and the CJEU’s judgment in BlackRock Investment Management (UK) Ltd, Case C-231/19.
What GfC20 actually locks
Funds are managed by a fund manager who supplies investment management and administration to the fund. Managers routinely outsource pieces — or the whole stack — under Master Services Agreements. Those outsourced supplies are normally made to the manager, not magically exempt because the manager itself makes exempt supplies.
For a third-party supply to the manager to be exempt, two conditions must both hold:
- the fund is a qualifying special investment fund (SIF) within Items 9 or 10; and
- the services, viewed broadly, form a distinct whole that is specific to and essential for management of that qualifying fund.
Physical or purely technical services fall outside. That is the long-standing Abbey National / GfBk line, restated in VATFIN5350: administration can be “management,” but a solicitor drafting a prospectus is still legal services.
GfC20’s operational punch is the next step. A single supply of fund management has a single VAT liability. You cannot apportion one indivisible package between qualifying and non-qualifying funds. You cannot claim exemption because “most” of the book is SIFs. The supply must be made solely in respect of qualifying funds, or the whole single supply is taxable. That is BlackRock, written into compliance language.
BlackRock is the spine, not a footnote
In BlackRock, the CJEU held that a single supply of platform/management services used across SIFs and non-SIFs could not be split or majority-tested into partial exemption. A single supply gets one treatment. HMRC now says the same thing without apology in GfC20: do not use single/multiple characterisation to stretch the exemption beyond the statute.
That is why the single-vs-multiple analysis is not academic. If your outsourced stack is characterised as one indivisible supply across a mixed book, BlackRock taxes the lot. If the economic reality is multiple supplies — fund-by-fund, with separate aims, delivery and pricing — some legs may still qualify for exemption where each leg is solely for SIFs and is specific and essential management. Get the characterisation wrong and you either under-account output tax or over-claim input recovery for years.
The four indicators CFOs should force into the file
HMRC says there are no bespoke fund-management single/multiple rules. Normal VAT principles apply. The starting point is still Card Protection Plan (ancillary) and Levob (closely linked indivisible whole), summarised in the VAT Supply and Consideration manual. Where the answer is not obvious, GfC20 lists four indicators. All four should be considered; none is ranked above the others.
1. Number of suppliers. Supplies by two separate legal entities are not normally a single supply. Sham structures will not save you.
2. View of the typical consumer. Here the typical consumer is the fund manager (or other recipient). Multiple-supply signals include separate aims and bespoke decision-making per fund, and the ability to run the business if only some elements are taken. Single-supply signals include a standardised package for all funds with no fund-level choice, and a dependency on receiving everything together from the same supplier.
3. Contract terms and economic reality. A single MSA is not determinative. HMRC will look under the MSA. Multiple-supply signals: fund-level schedules, services tailored per fund, delivery that does not support other funds, bottom-up pricing (including AUM-linked fees per fund), and invoices that identify fees by fund. Single-supply signals: no fund-level documentation, generic identical delivery, and a single package price or top-down cost allocation.
4. Intention of the legislation. Do not use packaging to extend exemption. BlackRock again: one supply, one liability; majority SIF use does not rescue a mixed single supply.
For PE and multi-strategy houses, the practical tell is often pricing and invoicing. If the administrator bills one blended fee and the finance team then allocates it in the management accounts, you are living in single-supply territory. If each fund has its own schedule, NAV output, and fee line, you have a fighting chance of multiple supplies — but only if the economic reality matches the paper.
What every CFO should lock this week
Map the book by SIF vs non-SIF. Use VATFIN5100 and the post-Claverhouse / post-2020 property-fund scope. Closed-ended vehicles, ACFs, property collective vehicles and pension wrappers all have different edges. Do not let marketing labels decide the tax label.
Re-paper the MSA stack. Pull every MSA, statement of work, fund schedule, fee card and invoice template. Test them against GfC20’s indicators in writing. Where the contract says “one package” but operations deliver fund-by-fund, either change the contract or change the VAT treatment — and keep the evidence HMRC says it will accept if economic reality diverges from the MSA.
Kill majority-based apportionment on single supplies. If the supply is single and the book is mixed, plan for 20% on the whole outsourced charge (including reverse charge on non-UK suppliers). Partial exemption on your onward supplies is a separate question; do not smuggle BlackRock risk into the recovery percentage.
Segregate pure tech and pure legal. Custody interfaces, generic IT, pure research outside MiFID-style management support, and standalone legal drafting should not be force-fitted into the management exemption. VATFIN5350 is still the boundary document.
Error correction path. If GfC20 shows you have been wrong, correct under VAT Notice 700/45 and put “GfC20” in the reason box. HMRC is inviting that reference for a reason — use it, and read the compliance checks factsheets on penalties before you assume “careless” is automatic.
Board and audit-committee pack. One page: SIF map, top five outsourced counterparties, single/multiple conclusion per counterparty, VAT at stake, correction status, and who owns the next MSA renewal. For PE portfolio CFOs, put the same page in the holdco tax risk register where the manager sits in the UK VAT group.
Why this matters beyond pure asset managers
Portfolio companies that run captive investment vehicles, treasury platforms shared across funds, or group fintech tools used by both regulated funds and proprietary books are in the same blast radius. So are administrators, depositaries and outsourcers who have been treating “everything under the MSA” as exempt management because the client is a manager. GfC20 is explicit: outsourcing does not inherit exemption by association.
The Autumn Budget window will not soften this. GfC20 is compliance guidance under existing law. Waiting for a soft landing is not a strategy.
Bottom line
GfC20 restates a hard rule in CFO language: characterise the supply first; apply the SIF exemption second; never apportion a single mixed supply. BlackRock closed the majority-use escape hatch years ago. HMRC has now published the indicator set it will use on MSAs, fee cards and invoices. Lock the SIF map, test every outsourced stack against the four indicators, correct with the GfC20 tag where needed, and put the residual VAT cash at risk on the audit committee agenda before the next return cycle — not after the enquiry letter.
