A CCA shares R&D cost by expected benefit — it is not an equal split of group revenue
A cost contribution arrangement (CCA) is a framework agreement under which group companies jointly contribute cash, personnel or assets to a shared R&D programme and, in return, each participant may exploit the results in its own territory without paying an internal royalty for those results. Unlike a contract R&D service (one party performs, the other pays cost plus a mark-up), in a CCA every participant is an economic co-owner of the outcome and shares the risk of failure. Vietnamese transfer pricing law has no chapter named ‘CCA’; the arrangement is tested through the arm’s length principle and the benefit test of the transfer pricing framework applicable by period — Decree 132/2020/ND-CP for 2025 and Decree 255/2026/ND-CP from 2026 (this article asserts no article numbers of Decree 255/2026, whose full text the team has not read).
Each party’s contribution share must match the benefit it expects from the R&D results — for example expected share of the assigned territory’s market, projected revenue from products applying the results, or expected unit volumes. Splitting by current group revenue is the weakest evidence, because today’s revenue says nothing about expected benefit from technology not yet on the market. A Vietnamese participant should prepare a supportable benefits projection (business plan, market forecast) at signing and update it when assumptions change materially.
Mandatory CCA clauses and the two events everyone forgets: buy-in and buy-out
A defensible CCA contains at least: the participants and the territory or market each may exploit; a description of the R&D programme and staged budgets; the criteria for contribution shares and a true-up mechanism when actual benefits diverge from projections; the forms of contribution (cash, personnel, shared assets) and how non-cash contributions are valued; ownership and use rights in results, including failed results; term and termination. The two events usually forgotten are the buy-in payment, when a new subsidiary joins a CCA that already holds accumulated results and must pay for the value it receives, and the buy-out, when a departing participant keeps rights in results already created. Without these mechanisms, the authority may recharacterise all contributions as disguised royalties or service fees.
Contributions of personnel and shared assets must be valued at the market price of equivalent resources, not mechanically at book cost. Every outbound CCA cash flow should also be screened for foreign contractor tax by the nature of each payment, because the authority may reclassify a contribution as a royalty if the Vietnamese party in substance only buys rights in existing results.
Vietnam accepts CCAs on substance: the expected-benefit file is the centre of gravity
Vietnam has no CCA registration or pre-approval; acceptance shows itself in whether contributions survive a transfer pricing audit and remain deductible. The file should hold the signed CCA, the Vietnamese party’s expected-benefit analysis, evidence of actual contributions, R&D progress reports proving the programme is real and running, and a comparability analysis showing the Vietnamese contribution does not exceed what an independent party would contribute for the same expected benefit. If the Vietnamese company contributes every year but never exploits the results in its assigned market, the benefit test collapses and the contributions risk disallowance.
Review the CCA annually together with the transfer pricing file: check contribution shares still track actual benefits, document adjustments, and make sure the contribution figures in the accounts, the related-party disclosure and the CCA file are one single set of numbers.
Frequently Asked Questions
How do several companies sharing R&D costs split them?
By expected benefit: each participant contributes in proportion to the benefit it expects from the R&D results (assigned market, projected revenue from products applying them). Contributions may be cash, personnel or shared assets, with non-cash items valued at market prices. Do not split by group revenue — that cannot demonstrate the link to the specific R&D programme’s benefits.
What clauses does a cost contribution arrangement (CCA) need?
A CCA needs: participants and each party’s exploitation territory; the R&D programme description and budgets; criteria for contribution shares plus a true-up mechanism; valuation of personnel/asset contributions; ownership and use rights in results; buy-in payments for newcomers receiving existing results and buy-out terms; duration and termination clauses.
Does Vietnam’s tax authority recognize it?
Yes, on substance — Vietnam has no separate CCA approval procedure. Contributions are accepted where the Vietnamese party documents its expected benefit, the R&D programme is real, contributions follow the arm’s length principle under the transfer pricing framework of the period (Decree 132/2020/ND-CP for 2025; Decree 255/2026/ND-CP from 2026), and the file is complete. Contributing without ever exploiting the results risks the contributions being disallowed.
