In May 2025 the Coordination Group Transfer Pricing of the Dutch Tax Authorities (CGVP) issued practical guidance on applying the cost‑plus method (CPM), particularly on what to include in the cost base. The CPM is often the appropriate transfer pricing method in case of supply of intragroup products or services. In practice, the net cost plus method (NCPM) is used most, since comparison on a gross-profit level is often complicated by lack of reliable information on, amongst others, raw material costs. One main area of attention is whether or not to include raw materials into the cost base.
Application of Cost Plus Methods
Both the CPM and NCPM are suitable methods in case the service or product is supplied internally within the group, i.e. is not sold to external third parties. Examples include routine, low‑complexity intra‑group functions where costs provide a reliable indicator of value, and the value added by the tested party is low. Consequently, the risks born by such an entity are also low.
(Gross) CPM versus NCPM – cost base
Three main types of costs can be distinguished:
The cost base using the CPM consists of both direct and indirect production costs. By contrast, the cost base of the NCPM also includes operating expenses which cannot be reliable attributed to a specific transaction. This is illustrated below using a simplified example P&L:
Turnover |
100 |
|
|||||||
Cost of Goods Sold (COGS) |
80 |
|
-/- |
||||||
Gross Profit (GP) |
20 |
|
(Gross) CPM = GP/COGS = 20/80 = 25% |
||||||
Operating Expenses (OPEX) |
10 |
|
-/- |
||||||
Net Profit (EBIT) |

NCPM = EBIT/(COGS+ OPEX) = 10/(80+10) = 11,11% |

When taking a closer look at this new guidance, three specific topics are addressed in more detail: A) raw materials; B) budget versus actual costs; and C) the appropriate markup applied.
A) Raw materials
The guidance clarifies which factors may indicate that the manufacturer has control over certain functions, assets and risks, in which case the raw material costs need to be included in the cost base. Examples include: transformation of raw materials into a finished product; relatively high value added in the production process; decision making authority regarding the R&D process; or obsolescence risk. Contractual agreements are always the starting point of such analysis, but the actual conduct of parties with respect to the functions and risks are decisive whether or not to include the direct production costs into the cost base.
Other helpful indicators to determine whether the manufacturer is actively involved in activities related to the raw materials are: involvement in price negotiations; determination of specifications and volumes; hedging of price - and currency risks; and quality control. By publishing these concrete practical pointers, companies can better substantiate and defend whether these costs in fact belong in their cost base or not.
B) Budgeted versus actual costs
Arm’s‑length arrangements typically rely on budgeted or standard costs. Helpful practical guidance is provided on what factors to consider when determining the appropriate cost base.
Efficiency / capacity / pricing results
Specification of costs
Financing costs and replacement costs
Pass-through costs
Fully loaded versus marginal cost
C) Mark-up itself
