Introduction to CA
If a group company or subsidiary (an associated enterprise [“AE”]) has had to pay additional tax in a foreign country, as a result of a transfer pricing (“TP”) adjustment in that country; CA is the mechanism available to compensate for that additional foreign tax; essentially allowing an adjustment to the Irish profits of the Irish taxpayer.
This mechanism only works where there is a Double Taxation Agreement (“DTA”) with that other country.
The purpose of CA is to provide the taxpayer (who is Irish resident for treaty purposes) with relief from economic double taxation i.e. taxation of the same profit in both Ireland and in another country where the AE is located.
Eligibility conditions
- Condition 1: DTA is in place between Ireland and the country of AE; and
- Condition 2: Presence of Article equivalent to Article 9 of the OECD Model Tax Convention on Income and Capital (“MTC”); or AE’s Country is a Multilateral Instrument (“MLI”) signatory and has fully adopted Article 17 of MLI
Procedure to claim
- Form & Contents: Form CA1 – Revenue prescribed claim form (along with detailed list of information required)
- Mode of submission:
- Original: To the Revenue Division/Branch dealing with the Irish taxpayers’ affairs; and
- Copy: To the Revenue Transfer Pricing Branch of the International Tax Division
- Language: English or Irish
Review by Revenue
The Revenue officer will review the claim and accept the claim - to the extent, they consider the primary adjustment justified in both principle and value terms. Accordingly, the claim may be wholly or partly accepted; or wholly rejected.
Claim Accepted (Wholly or Partially) | Claim Rejected (Wholly) |

Special considerations
- Irish tax law does not allow a deduction for additional tax paid as a result of TP adjustments in other countries. The CA rules under DTAs is the appropriate mechanism to relieve Irish taxpayers from any potential double taxation.
- Revenue is not bound to accept a CA claim, merely because a TP adjustment is imposed by another tax authority. The Revenue will only accept the CA claim, to the extent it considers the overseas adjustment is justified in both principle and value terms.
- The taxpayer can make a fresh CA claim, even if it has already submitted a CA claim which is either still under review or has been refused by Revenue before the publication of this guidance.
- CA will not include relief for:
- Secondary adjustments such as imputed or notional interest on intercompany balances;
- Interest on unpaid taxes; and
- Statutory penalties.
Way forward
The Revenue TDM provides detailed guidance on the procedural mechanisms for the application of correlative adjustment-related Article under Ireland’s DTA network. The appropriateness and acceptance of the CA claim depends to a large extent on the completeness and accuracy of the submission made to Revenue.
In a case where the CA claim is wholly or partially rejected by Revenue, it is important to make a submission to the respective tax authorities in the prescribed manner, within the specified time limit. Failure to do so may lead to the appeal application being rejected. It should also be noted that an incorrect claim to Revenue could, in some circumstances, lead to penal consequences.
While the CA proceedings provide an opportunity for the Irish entity to claim double taxation relief, the large amount of documentation required to be submitted, along with the tight time limits, can act as potential hurdles.
Next steps
We strongly recommend that companies who suffer overseas TP adjustments seek prompt advice from their tax advisors.
In support of your CA claim, we can work with you to provide the following:
- Compile relevant documentation at the group level, enabling the Irish entity to obtain complete and accurate evidence/documents (including any audit papers) from its AE; and
- Be fully aware of the historical and current tax positions taken by the AEs in their respective jurisdictions (at all stages - from the starting date of the transaction to the conclusion of the audit or appeal).
