Plain English
Full transfer pricing compliance is expensive relative to the size of a smaller company's cross-border transactions, so many countries carve out relief for businesses below certain revenue, headcount or balance sheet thresholds. This does not usually mean the arm's length principle stops applying — the underlying pricing must generally still be at arm's length — but the formal documentation and filing burden is reduced or removed entirely.
Technical definition
Statutory or administrative provisions that exempt taxpayers meeting defined small and medium-sized enterprise (SME) criteria — commonly based on consolidated group revenue, balance sheet total, or employee headcount — from some or all formal transfer pricing documentation obligations, while generally preserving the substantive requirement that related-party transactions be priced consistently with the arm's length principle.
Why it matters
For smaller multinationals and growing businesses, correctly identifying and applying an available SME exemption can materially reduce compliance cost without increasing genuine tax risk, provided the underlying pricing remains defensible.
How it works in practice
- 01Determine the applicable size threshold (revenue, balance sheet, or headcount) in each relevant jurisdiction.
- 02Assess the group's consolidated figures against those thresholds, since most exemptions are tested at group level.
- 03Confirm whether the exemption removes documentation obligations entirely or merely simplifies the required format.
- 04Retain a basic rationale for pricing decisions even where full documentation is not legally required.
- 05Monitor thresholds annually, since growth can cause a group to lose exemption status.
Worked example
A growing group crossing the threshold
A UK-based group with consolidated turnover under GBP 10.2m has historically relied on the UK's SME exemption from mandatory transfer pricing documentation. Following an acquisition, group turnover rises to GBP 15m, pushing it into the medium-sized company band, which under UK rules removes exemption from Section 482 TIOPA transfer pricing rules for transactions with certain non-qualifying territories, though full documentation obligations under UK rules generally still track the OECD Action 13 framework only once even larger CbC thresholds are met. The group's finance team flags the acquisition-driven threshold change to tax proactively rather than discovering it at the next audit.
Common mistakes
- Testing the exemption threshold against a single entity's turnover rather than the consolidated group figure.
- Assuming an SME exemption removes the substantive arm's length requirement, not just the documentation burden.
- Failing to reassess exemption status after an acquisition or organic growth pushes the group over a threshold.
Audit red flags
- No annual recheck of group size against relevant thresholds.
- Reliance on an exemption without any documented rationale for intercompany pricing at all.
- Group structures using multiple thin entities apparently designed to stay under a threshold artificially.
Documentation & data
Documents to hold
- A basic pricing rationale memo, even where full documentation is not mandatory.
- Annual group-size calculation evidencing continued exemption eligibility.
- Records of any transactions specifically excluded from an available exemption (e.g., transactions with listed non-cooperative jurisdictions).
Data you need
- Consolidated group revenue, balance sheet and headcount figures.
- The specific SME threshold definitions in each relevant jurisdiction.
- A list of transactions potentially carved out of the exemption regardless of size.
Who owns this internally: In-house tax and finance jointly monitor group size thresholds affecting exemption status.
Jurisdiction notes
- United Kingdom
- SME exemption from UK transfer pricing rules generally applies to small enterprises entirely and medium enterprises for most transactions, subject to specific carve-outs (e.g., transactions with non-qualifying territories) under TIOPA 2010.
- European Union
- Several member states use the EU's SME definition (under 250 employees, turnover under EUR 50m) as the basis for simplified transfer pricing documentation regimes.
- United States
- No formal SME exemption exists federally; smaller taxpayers still fall under IRC Section 482 but documentation is proportionate in practice to transaction materiality.
Notes by role
CFOs & finance leaders
An SME exemption is a compliance cost saving, not a tax risk waiver — do not let it be mistaken internally for permission to price transactions arbitrarily.
In-house tax teams
Build threshold monitoring into the annual close process, since M&A activity is the most common trigger for losing SME status unexpectedly.
Frequently asked
- Does an SME exemption mean transfer pricing rules do not apply at all?
- Generally no — the arm's length principle still applies substantively; what is typically waived is the formal documentation and filing obligation.
- Is the SME threshold tested at the local entity or global group level?
- Almost always at the consolidated global group level, not the individual local entity, which surprises many growing businesses.
