Mauritius
This report analyses the implementation of the AEOI Standard in Mauritius with respect to the requirements of the AEOI Terms of Reference. It assesses both the legal frameworks put in place to implement the AEOI Standard and the effectiveness of the implementation of the AEOI Standard in practice.
The methodology used for the peer reviews and that therefore underpins this report is outlined in Chapter 2.
Overall findings
AEOI legal framework
Mauritius’ legal framework implementing the AEOI Standard is in place and is consistent with the requirements of the AEOI Terms of Reference. This includes Mauritius’ domestic legislative framework requiring Reporting Financial Institutions to conduct the due diligence and reporting procedures (CR1) and its international legal framework to exchange the information with all of Mauritius’ Interested Appropriate Partners (CR2).
Effectiveness of AEOI in practice
Mauritius’ implementation of the AEOI Standard is on track with respect to the requirements of the AEOI Terms of Reference to ensure the effectiveness of the AEOI Standard in practice. This includes ensuring Reporting Financial Institutions correctly conduct the due diligence and reporting procedures (CR1) and exchanging the information in an effective and timely manner (CR2). Mauritius is encouraged to continue its implementation process accordingly, to ensure its ongoing effectiveness.
Overall rating in relation to the effectiveness in practice: On Track
General context
Mauritius commenced exchanges under the AEOI Standard in 2018.
In order to provide for Reporting Financial Institutions to collect and report the information to be exchanged, Mauritius:
introduced the Income Tax (Common Reporting Standard) Regulations 2016, as amended by the Income Tax (Common Reporting Standard) Regulations 2019 and GN 87/2019; and
Under this framework Reporting Financial Institutions were required to commence the due diligence procedures in relation to New Accounts from 1 January 2017. With respect to Preexisting Accounts, Reporting Financial Institutions were required to complete the due diligence procedures on High Value Individual Accounts by 31 December 2017 and on Lower Value Individual Accounts and Entity Accounts by 31 December 2018.
Following the initial Global Forum peer review, Mauritius amended its legislative framework to address issues identified, effective from 23 April 2019.
With respect to the exchange of information under the AEOI Standard, Mauritius is a Party to the Convention on Mutual Administrative Assistance in Tax Matters and activated the associated CRS Multilateral Competent Authority Agreement in time for exchanges in 2018.
Table 1 sets out the number of Financial Institutions in Mauritius that reported information on Financial Accounts in 2021 as defined in the AEOI Standard (essentially because they maintained Financial Accounts for Account Holders, or that were related to Controlling Persons, resident in a Reportable Jurisdiction). It also sets out the number of Financial Accounts that they reported in 2021. In this regard, it should be noted that Mauritius requires the reporting of Financial Accounts based on a prescribed list of exchange partners and some accounts may be required to be reported more than once (e.g. jointly held accounts or accounts with multiple related Controlling Persons), which is reflected in the figures below. These figures provide key contextual information to the development and implementation of Mauritius’ administrative compliance strategy, which is analysed in the subsequent sections of this report.
Table 2 sets out the number of exchange partners to which information was successfully sent by Mauritius in the past few years (including where the necessary frameworks were in place, containing an obligation on Reporting Financial Institutions to report information, but no relevant Reportable Accounts were identified). These figures provide key contextual information in relation to Mauritius’ exchanges in practice, which is also analysed in subsequent sections of this report.
In order to provide for the effective implementation of the AEOI Standard, in Mauritius:
the Mauritius Revenue Authority (the tax authority) has the responsibility to ensure the effective implementation of the due diligence and reporting obligations by Reporting Financial Institutions and for exchanging the information with Mauritius’ exchange partners;
technical solutions necessary to receive and validate the information reported by Reporting Financial Institutions were put in place by the Mauritius Revenue Authority, which ensure the validation of the data reported by Financial Institutions before it is exchanged with Mauritius’ exchange partners; and
the Common Transmission System (CTS) is used for the exchange of the information, along with the associated file preparation and encryption requirements.
It should be noted that the review of Mauritius’ legal frameworks implementing the AEOI Standard concluded with the determination that Mauritius’ domestic and international legal frameworks are In Place. This has been taken into account when reviewing the effectiveness of Mauritius’ implementation of the AEOI Standard in practice.

Findings and conclusions in relation to effectiveness in practice
The detailed findings and conclusions in relation to effectiveness in practice of AEOI for Mauritius are below, organised per Core Requirement (CR) and then per sub-requirement (SR) as extracted from the AEOI Terms of Reference (see Annex C).
CR1 Effectiveness in practice: Jurisdictions should ensure that in practice Reporting Financial Institutions correctly implement the due diligence and reporting procedures, which includes a requirement for jurisdictions to have in place an administrative framework to ensure the effective implementation of the CRS.
Mauritius’ implementation of the AEOI Standard is on track with respect to ensuring that Reporting Financial Institutions are correctly conducting the due diligence and reporting procedures and are therefore reporting complete and accurate information. This includes ensuring effectiveness in a domestic context, such as through having an effective administrative compliance framework and related procedures (SR 1.5), and collaborating with exchange partners to ensure effectiveness (SR 1.6). Mauritius is encouraged to continue its implementation process to ensure its ongoing effectiveness.
SR 1.5 Jurisdictions should ensure that in practice Reporting Financial Institutions identify the Financial Accounts they maintain, identify the Reportable Accounts among those Financial Accounts, as well as their Account Holders, and where relevant Controlling Persons, by correctly conducting the due diligence procedures and collect and report the required information with respect to each Reportable Account. This includes having in place:
an effective administrative compliance framework to ensure the effective implementation of, and compliance with, the CRS. This framework should:
be based on a strategy that facilitates compliance by Reporting Financial Institutions and which is informed by a risk assessment in respect of the effective implementation of the CRS that takes into account relevant information sources (including third party sources);
include procedures to ensure that Financial Institutions correctly apply the definitions of Reporting Financial Institutions and Non-Reporting Financial Institutions;
include procedures to periodically verify Reporting Financial Institutions’ compliance, conducted by authorities that have adequate powers with respect to the reviewed Reporting Financial Institutions, with procedures to access the records they maintain; and
effective procedures to ensure that Financial Institutions, persons or intermediaries do not circumvent the due diligence and reporting procedures;
effective enforcement mechanisms to address non-compliance by Reporting Financial Institutions;
strong measures to ensure that valid self-certifications are always obtained for New Accounts;
effective procedures to ensure that each, or each type of, jurisdiction-specific Non-Reporting Financial Institution and Excluded Account continue to present a low risk of being used to evade tax; and
effective procedures to follow up with a Reporting Financial Institution when undocumented accounts are reported in order to establish the reasons why such information is being reported.
In order to ensure that Reporting Financial Institutions correctly conduct the due diligence and reporting procedures, Mauritius implemented all of the requirements in accordance with expectations. The key findings were as follows:
Mauritius implemented an overarching strategy to ensure compliance with the AEOI Standard developed after conducting a risk assessment that took into account relevant information sources, such as the analysis of data submitted by Reporting Financial Institutions, compliance questionnaires and additional information provided by the Financial Services Commission. Mauritius’ compliance strategy facilitates compliance and incorporates a credible approach to enforcement. Mauritius intends to keep its compliance strategy and risk assessment under review to ensure its effectiveness on an ongoing basis.
Mauritius has worked effectively to understand its population of Financial Institutions, including relevant non-regulated entities, utilising various relevant information sources, such as the list of entities licensed by the Bank of Mauritius, the Foreign Financial Institution list for FATCA purposes and the lists of licensed management companies and trustees from the Financial Services Commission (the regulator of the non-bank financial markets of Mauritius). Mauritius is taking action to ensure that Reporting Financial Institutions are classifying themselves correctly under its domestic rules and reporting as required. Mauritius intends to keep its understanding of its Financial Institution population up to date on a routine basis.
The institution responsible for implementing Mauritius’ compliance strategy appears to have the necessary powers and resources to discharge its functions. With respect to resourcing, Mauritius has assigned the equivalent of three full time staff to monitor and ensure compliance by Reporting Financial Institutions, which have access to IT systems and tools to conduct risk assessments. Overall, they appear to have effectively implemented an operational plan to verify compliance with the requirements, incorporating appropriate compliance activities.
It appears that Mauritius effectively enforces the requirements, including through conducting desk-based and onsite visits, the inspection of records of Reporting Financial Institutions as well as through follow-up visits, and that Mauritius applies penalties and sanctions in relation to Reporting Financial Institutions that failed to report information or that were late in reporting information. It also appears that Mauritius is ready to take effective action to address circumvention of the requirements if such circumvention is detected. It was noted that Mauritius has taken effective action to ensure self-certifications are obtained as required and effectively follows up on undocumented accounts.
Mauritius will also keep its jurisdiction-specific Excluded Account category of dormant accounts under review to ensure they continue to pose a low risk of being used for tax evasion purposes (Mauritius does not have a jurisdiction-specific list of Non-Reporting Financial Institutions).
Table 3 provides a summary of the specific activities undertaken, or that are planned to be undertaken, in relation to each of the key parts of the framework described above.
With respect to the Financial Account information collected and sent by Mauritius, the presence of the key data points of the Tax Identification Numbers and dates of birth appeared to be in line with most other jurisdictions. Information provided by Mauritius showed a higher number of undocumented accounts reported by its Reporting Financial Institutions, when compared to other jurisdictions, which should only occur when it is not possible for the Reporting Financial Institution to identify whether the accounts are held by Reportable Persons. However, the number of undocumented accounts has reduced over time. Follow-up discussions confirmed that Mauritius is aware of this issue and is taking steps to address it.
Feedback was also received from Mauritius’ exchange partners, indicating that, compared to what they generally experience in relation to the information received from all of their exchange partners, they achieved a relatively lower level of success when seeking to match information received from Mauritius with their taxpayer database. While some exchange partners highlighted issues with respect to the information received, such as invalid Tax Identification Numbers, it was noted that most of the issues pertain to earlier reporting years and now more regular checks are being performed by Mauritius. One exchange partner highlighted particular issues related to variations in the amount of data sent between different reporting periods, but these issues have already been resolved. Follow-up discussions confirmed that Mauritius is aware of the remaining issues and is taking steps to address them.
Based on these findings it was concluded that, overall, Mauritius is meeting expectations in ensuring that Reporting Financial Institutions correctly conduct the due diligence and reporting procedures, including by having in place the required administrative compliance framework and related procedures. It was also noted that there is room for improvement with respect to addressing the issues raised by its exchange partners. Mauritius is therefore encouraged to continue its implementation process accordingly, including by addressing the recommendation made.
Mauritius should continue to work with its exchange partners to address the issues raised.
SR 1.6 Jurisdictions should collaborate on compliance and enforcement. This requires jurisdictions to:
use all appropriate measures available under the jurisdiction’s domestic law to address errors or non-compliance notified to the jurisdiction by an exchange partner; and
have in place effective procedures to notify an exchange partner of errors that may have led to incomplete or incorrect information reporting or non-compliance with the due diligence or reporting procedures by a Reporting Financial Institution in the jurisdiction of the exchange partner.
In order to collaborate on compliance and enforcement, Mauritius implemented all of the requirements in relation to issues notified to them (i.e. under Section 4 of the MCAA or equivalent) in accordance with expectations. In particular, Mauritius received a notification from one partner and successfully processed them in a timely manner, resolving the issues raised. It also appears that Mauritius will notify its partners effectively of errors or suspected non-compliance it identifies when utilising the information received.
Based on these findings it was concluded that Mauritius is fully meeting expectations in relation to collaborating with its exchange partners to ensure that Reporting Financial Institutions correctly conduct the due diligence and reporting procedures. Mauritius is therefore encouraged to continue its implementation process accordingly, to ensure its ongoing effectiveness.
CR2 Effectiveness in practice: Jurisdictions should exchange the information effectively in practice, in a timely manner, including by sorting, preparing, validating and transmitting it in accordance with the AEOI Standard.
Mauritius’ implementation of the AEOI Standard is on track with respect to exchanging the information effectively in practice, including in relation to sorting, preparing and validating the information (SR 2.4), correctly transmitting the information in a timely manner (SRs 2.5 – 2.8) and providing corrections, amendments or additions to the information (SR 2.9). Mauritius has shown improvement over time and is encouraged to continue its implementation process accordingly, to ensure its ongoing effectiveness.
SR 2.4 Jurisdictions should sort, prepare and validate the information in accordance with the CRS XML Schema and the associated requirements in the CRS XML Schema User Guide and the File Error and Correction-related validations in the Status Message User Guide (i.e. the 50000 and 80000 range).
Two exchange partners highlighted particular issues with respect to preparation and format of the information sent by Mauritius (representing 3% of its partners). These generally related to file rejections due to record errors and referencing issues. More generally, eight (or 11%) of Mauritius’ exchange partners reported rejecting more than 25% of the files received, of which one reported rejecting more than 50% of files received, due to the technical requirements not being met. This is a relatively high amount when compared to other jurisdictions. It was noted that many of the issues raised pertain to earlier reporting years, after which Mauritius updated its reporting system to prevent them from occurring again. Mauritius is also in the process of addressing the remaining issues.
Based on these findings it was concluded that, overall, Mauritius is meeting expectations in relation to sorting, preparing and validating the information. It was also noted that there is room for improvement with respect to file errors. Mauritius is therefore encouraged to continue its implementation process accordingly, including by addressing the recommendation made.
Mauritius should continue to work with its exchange partners to address the issues raised.
SR 2.5 Jurisdictions should agree and use, with each exchange partner, transmission methods that meet appropriate minimum standards to ensure the confidentiality and integrity of the data throughout the transmission, including its encryption to a minimum secure standard.
In order to put in place an agreed transmission method that meets appropriate minimum standards in confidentiality, integrity of the data and encryption for use with each of its exchange partners, Mauritius linked to the CTS
Based on these findings it was concluded that Mauritius is fully meeting expectations in relation to agreeing and using appropriate transmission methods with each of its partners. Mauritius is encouraged to continue to ensure the ongoing effectiveness of its implementation.
SR 2.6 Jurisdictions should carry out all exchanges annually within nine months of the end of the calendar year to which the information relates.
Feedback from Mauritius’ exchange partners did not raise any concerns with respect to timeliness of the exchanges by Mauritius and therefore with respect to Mauritius’ implementation of this requirement.
Based on these findings it was concluded that Mauritius is fully meeting expectations in relation to exchanging the information in a timely manner. Mauritius is encouraged to continue to ensure the ongoing effectiveness of its implementation.
SR 2.7 Jurisdictions should send the information in accordance with the agreed transmission methods and encryption standards.
Feedback from Mauritius’ exchange partners did not raise any concerns with respect to Mauritius’ use of the agreed transmission methods and therefore with Mauritius’ implementation of this requirement.
Based on these findings it was concluded that Mauritius is fully meeting expectations in relation to sending the information in accordance with the agreed transmission methods and encryption standards. Mauritius is encouraged to continue to ensure the ongoing effectiveness of its implementation.
SR 2.8 Jurisdictions should have the systems in place to receive information and, once it has been received, should send a status message to the sending jurisdictions in accordance with the CRS Status Message XML Schema and the related User Guide.
One exchange partner highlighted delays in the sending of status messages by Mauritius. It was noted that Mauritius appears to be successfully addressing the issue to ensure that status messages are sent in accordance with the requirements.
Based on these findings it was concluded that Mauritius is fully meeting expectations in relation to the receipt of the information. Mauritius is encouraged to continue to ensure the ongoing effectiveness of its implementation.
SR 2.9 Jurisdictions should respond to a notification from an exchange partner as referred to in Section 4 of the Model CAA (which may include Status Messages) in accordance with the timelines set out in the Commentary to Section 4 of the Model CAA. In all other cases, jurisdictions should send corrected, amended or additional information received from a Reporting Financial Institution as soon as possible after it has been received.
Mauritius appears ready to respond to notifications and to provide corrected, amended or additional information in a timely manner and no such concerns were raised by Mauritius’ exchange partners.
Based on these findings it was concluded that Mauritius appears to be meeting expectations in relation to responding to notifications from exchange partners and the sending of corrected, amended or additional information. Mauritius is encouraged to continue to ensure the ongoing effectiveness of its implementation.
