Distributor transfer pricing sets the return earned by a group entity that buys, sells, markets, warehouses, or supports sales of products. The method depends on what the distributor actually does and which risks it controls.
For routine buy-sell distributors, the two most common methods are:
RPM is often cleaner in theory because it tests the distributor's resale margin directly. TNMM is often easier to defend in practice when gross-margin comparability is weak. For a full method comparison, see the resale price method guide, CPM vs TNMM, and how to choose the best transfer pricing method.
The label "limited-risk distributor" does not settle the pricing. The file still needs to show that the local entity's contracts, conduct, risk control, financial capacity, and actual results fit a limited-risk return.
The first step is characterizing the local sales entity. Similar legal invoices can describe different economics.
| Profile | Legal flow | Typical functions | Typical pricing approach |
|---|---|---|---|
| Sales agent | Principal sells to customer; agent supports sales | Lead generation, customer support, no title to goods | Commission or cost-plus service return |
| Commissionaire | Acts in own name, often for principal's account | Sales execution, limited inventory role | Commission or TNMM depending on facts |
| Buy-sell distributor | Buys goods and resells to customers | Sales, warehousing, logistics, ordinary inventory and credit functions | RPM or TNMM |
| Limited-risk distributor | Buy-sell distributor with risk contractually and practically limited | Routine selling, execution of group strategy | TNMM operating margin, RPM if gross data supports it, Amount B where applicable |
| Full-fledged distributor | Local entrepreneur | Pricing strategy, market development, inventory risk, local intangibles | Broader return, sometimes profit split or residual analysis |
The tested party is usually the local distributor when it is the less complex entity and reliable comparable distributors can be found. For the tested-party framework, see tested party selection.
A routine distributor performs ordinary sales and distribution functions without owning unique intangibles or controlling major business risks. It may still matter commercially. Routine does not mean passive.
A limited-risk distributor (LRD) is a narrower profile. It typically buys goods from a related principal and resells them locally, but the principal controls or absorbs major risks.
| Area | LRD-friendly evidence | Audit concern |
|---|---|---|
| Market risk | Principal sets strategy and bears downside through price adjustments or support | Local team independently decides strategy and absorbs losses |
| Inventory risk | Principal controls product planning, obsolescence policy, and buybacks | Local entity funds and controls stock risk |
| Credit risk | Credit policy is centrally controlled or reimbursed | Local entity sets credit policy and bears bad debts |
| Product risk | Principal owns product IP, warranty design, and product roadmap | Local entity manages warranty exposure or product adaptation |
| Marketing intangibles | Local spend is routine and reimbursed or budget-controlled | Local entity funds brand-building and owns local market intangibles |
| Pricing | Transfer pricing policy creates routine target return | Local entity freely sets resale and purchase economics |
Contracts matter, but conduct matters more. If the contract says the principal bears inventory risk while the local entity decides what to buy, when to discount, and how to liquidate obsolete stock, the limited-risk story will be challenged.
LRDs can lose money for a short period, but recurring losses need a specific explanation. Tax authorities often ask why an entity described as limited-risk bears multi-year losses if the principal controls the risk profile.
Buy-sell distributors take title to inventory and sell to third-party customers. That legal form creates more method options than an agency model.
The usual questions are:
A buy-sell distributor can be routine, limited-risk, or entrepreneurial. The transfer pricing method follows the functional profile, not the invoice flow alone.
RPM and TNMM often compete in distribution cases. The choice usually turns on data quality.
The resale price method starts from the third-party resale price and subtracts an arm's length gross margin for the distributor.
RPM tends to work when:
RPM is sensitive to accounting. Freight, rebates, warranty costs, inventory write-offs, and promotional allowances can sit above or below gross profit depending on accounting policy.
TNMM tests the distributor's net profitability, often using operating margin:
Operating margin = Operating profit / Sales
TNMM tends to work when:
TNMM is commonly used for LRDs because operating margin data is usually more available and less sensitive to gross-line accounting than RPM.
| Issue | RPM | TNMM |
|---|---|---|
| Profit level | Gross margin | Net margin |
| Data burden | Gross-margin comparables and accounting consistency | Net-margin comparables and PLI support |
| Product sensitivity | Higher | Lower, but still relevant |
| Common PLI | Gross margin on resale | Operating margin, sometimes Berry ratio |
| Typical audit challenge | Gross margin mismatch | Comparables too broad or tested party not routine |
If RPM and TNMM point in different directions, investigate the bridge between gross and operating profit. The issue may be accounting classification, local marketing spend, freight policy, rebates, or functions sitting below gross profit.
Amount B, now described by the OECD as the simplified and streamlined approach for baseline distribution activities, is aimed at in-country baseline marketing and distribution activities. The OECD's consolidated 2025 report states that jurisdictions can choose to apply the approach to qualifying transactions of eligible baseline distributors.
In practice, this means:
The OECD materials describe an approach for eligible baseline distributors that cannot, for example, assume certain economically significant risks or own unique and valuable intangibles. The consolidated report also notes exclusions for some activities, including commodities and digital goods.
IRS Notice 2025-04 announced that Treasury and the IRS intend to issue proposed regulations under section 482 for a simplified and streamlined approach for certain baseline marketing and distribution transactions. The notice frames the approach as a new method for pricing those transactions. US taxpayers should check the effective rules, elections, and later guidance before relying on it.
Do not treat Amount B as a shortcut for every LRD. First check the local law, the transaction scope, product exclusions, operating expense cross-check, documentation requirements, and whether applying the approach creates double-taxation risk in the counterparty jurisdiction.
A distributor benchmark should be built from the functional profile, not from the desired margin.
Separate:
Weak segmentation is a common reason distribution benchmarks fail. A distributor that also provides technical services or after-sales support may need separate analyses.
| Profile | Common method | Common PLI |
|---|---|---|
| Routine buy-sell distributor with reliable gross data | RPM | Gross margin |
| Limited-risk distributor | TNMM | Operating margin |
| Distributor with pass-through COGS and low risk | TNMM, occasionally Berry ratio | Berry ratio only with strong support |
| Agent or commissionaire | CUP, cost plus, or TNMM | Commission rate, net cost plus, or Berry ratio |
| Full-fledged distributor | Fact-specific | May need residual or broader analysis |
For PLI details, see the PLI selection guide and the benchmarking study guide.
Screen for independent companies with similar:
Avoid comparables that manufacture, own brands, develop products, provide major services, or act as retailers when the tested party is a wholesale LRD.
Common adjustments include:
For working capital mechanics, see working capital adjustments.
| Section | What tax authorities expect |
|---|---|
| Distributor characterization | Specific functions, assets, risks, decision rights, and local conduct |
| Intercompany agreement | Title flow, risk allocation, pricing policy, returns, rebates, warranties, and true-ups |
| Method selection | Why CUP, RPM, TNMM, Amount B, or another method was accepted or rejected |
| Segmentation | Tested transaction P&L with reconciliation to accounts |
| Benchmarking | Search strategy, filters, accept/reject matrix, final comparables, PLI, range |
| Local marketing | Who controls spend, who owns any intangibles, and whether spend is routine |
| Actual results | Tested-party margin, range comparison, true-up calculation |
| Local caveats | Amount B adoption, safe harbors, country preferences, and documentation deadlines |
The local file should also explain losses, restructuring years, new-market investments, or material changes in the distributor's contract.
If the distributor is limited-risk, authorities may ask why it bears losses. The answer may be startup activity, extraordinary market events, year-end timing, or foreign exchange. The file needs evidence.
High advertising and promotion spend can undermine a routine characterization if the local entity controls the spend and bears the risk. Reimbursement and budget approval help, but the conduct still needs review.
Independent distributors that own brands, manufacture products, operate retail stores, or provide major services may overstate the arm's length return for a routine wholesale distributor.
True-ups should match the contract, accounting records, customs/VAT treatment, and local tax rules. A late or one-sided true-up can create audit friction.
RPM may show one answer and TNMM another. Auditors often focus on the expense categories driving the difference.
Converting a full-fledged distributor to an LRD may require a separate restructuring or exit-charge analysis. See the transfer pricing documentation guide for documentation implications.
PolandCo buys finished products from PrincipalCo and resells them to unrelated customers in Poland. PolandCo has local sales staff, warehousing, order processing, and routine marketing. PrincipalCo owns product IP, sets product strategy, controls pricing corridors, approves major customer terms, and reimburses extraordinary warranty costs.
PolandCo's current-year results:
| Item | Amount |
|---|---|
| Third-party sales | EUR 50,000,000 |
| COGS from PrincipalCo | EUR 38,750,000 |
| Gross profit | EUR 11,250,000 |
| Operating expenses | EUR 9,500,000 |
| Operating profit | EUR 1,750,000 |
| Operating margin | 3.5% |
The team considers RPM because PolandCo resells goods without transformation. The gross-margin search is weak because potential comparables classify freight, rebates, warranty, and promotional costs inconsistently.
TNMM is selected using operating margin because PolandCo is a routine distributor, reliable net-margin comparables exist, and operating margin better absorbs gross-line classification differences.
A search for independent wholesale distributors produces this interquartile range:
| Statistic | Operating margin |
|---|---|
| Lower quartile | 2.2% |
| Median | 3.1% |
| Upper quartile | 4.4% |
PolandCo's 3.5% operating margin falls within the range. The file still documents why the LRD characterization is consistent with actual conduct, why RPM was rejected, and how year-end true-ups would operate if results fell outside the range.
Distributor transfer pricing determines the arm's length return for a related-party sales entity that buys, sells, markets, warehouses, or supports products. The analysis depends on the distributor's functions, assets, risks, and available comparable data.
There is no universal LRD margin. The return depends on the market, products, functions, risks, and comparables. Amount B may provide a simplified result for qualifying baseline distributors in adopting jurisdictions, but it is not a blanket margin for all LRDs.
RPM is better when gross-margin comparability is reliable. TNMM is often better when accounting differences, channel differences, or limited gross data make RPM less reliable. The method-selection section should compare both.
An LRD can report losses in unusual circumstances, but repeated losses need explanation. If the entity is priced as limited-risk, the file should show why the principal, not the distributor, controls and bears the relevant downside over time.
No. Amount B applies only where local rules adopt or implement it and only for in-scope transactions. Out-of-scope distributors still need standard transfer pricing analysis.
Operating margin is common for buy-sell distributors. Gross margin can be used under RPM when gross comparability is strong. Berry ratio is narrower and requires careful support, especially where the distributor takes title to goods or bears inventory risk.
