Mauritius E-Invoicing: MRA Requirements, EBS Rules & 2026 Deadlines

Mauritius operates a phased mandatory e-invoicing regime administered by the Mauritius Revenue Authority (MRA). Businesses within scope must use a compliant Electronic Billing System (EBS) to generate and issue electronic invoices, receipts, debit notes, and credit notes.

Compliance in Mauritius requires more than emailing a PDF invoice. In-scope businesses must use a certified Electronic Billing System (EBS). This system generates invoice data in JSON format, connects directly to the MRA, and validates transactions. It also produces invoices featuring mandatory data, including a unique QR code. Instead of a universal start date, the MRA uses a phased rollout based on turnover and taxpayer category. The authority can also mandate compliance for specific businesses via written notice.

Latest News

Mauritius has continued its phased e-invoicing rollout in 2026. Businesses with annual turnover above MUR 80 million were expected to join the MRA system during the 2025–26 financial year, while the MRA has also expanded the mandate to certain businesses with turnover above MUR 40 million from 1 September 2026.

Businesses should check their turnover band and any written MRA notification, as the Director-General may require a business to adopt e-invoicing regardless of turnover. The MRA also maintains an updated indicative list of EBS solution providers.

What Is E-Invoicing in Mauritius?

E-invoicing in Mauritius means generating and issuing invoices, receipts, debit notes, and credit notes through a billing system that meets Mauritius Revenue Authority (MRA) requirements. The legal framework is set out in the Value Added Tax (E-Invoicing) Regulations 2023, supported by the MRA’s Electronic Billing System (EBS) Functional Specifications.

Businesses can use an MRA-compliant EBS or adapt an existing ERP, accounting, POS, cash-register, or e-commerce system. The EBS must generate the required supplier, customer, transaction, and VAT data, process adjustments, securely retain records, and support reconciliation with sales, accounting, and VAT records.

The mandate is phased rather than universal: businesses should not assume they are outside scope solely because they fall below a published turnover threshold, or that every business became subject to e-invoicing on the same date. Once a supplier is in scope, its relevant invoices, receipts, debit notes, and credit notes must be processed through its compliant EBS and registered with the MRA before being issued to the customer

E-Invoicing Timeline

September 2023: Mauritius introduced the Value Added Tax (E-invoicing) Regulations 2023, establishing the legal framework for the national e-invoicing regime.

• 2023–2024: The MRA began onboarding Electronic Billing System providers and businesses to the e-invoicing framework.
• 15 May 2024:E-invoicing became mandatory for MRA-notified businesses with annual turnover above MUR 100 million.
• June 2025: The 2025–26 National Budget announced that suppliers with annual turnover above MUR 80 million would join the e-invoicing system during the financial year.
• Ongoing: Mauritius continues to expand e-invoicing in phases. Businesses should monitor MRA notices for their mandate status, onboarding deadline, technical requirements, and implementation date.

B2G E-Invoicing in Mauritius

B2G e-invoicing is mandatory only when the government supplier falls within the MRA’s general e-invoicing scope or receives a written notification from the MRA. 

The relevant public body, tender or contract may also impose additional procurement requirements, such as a purchase-order number, contract reference, supplier-registration detail or submission through a procurement platform. 

Businesses should distinguish MRA e-invoicing obligations from separate public-procurement invoicing or payment requirements.

In Mauritius, businesses must retain invoices and other business records for at least five years after the relevant transaction is completed.

B2B E-Invoicing

B2B e-invoicing applies where the supplier is within the phased MRA mandate or has received an MRA written notice. In-scope suppliers need to process relevant business-to-business invoices through their compliant EBS and include the required business, transaction and VAT information.

Commercial references such as purchase-order numbers, contract references, delivery references and customer account details may also be needed where required by the buyer, contract or internal workflow.

B2C E-Invoicing

B2C e-invoicing applies where the seller is in scope. The regime is not limited to sales to VAT-registered businesses: it also covers invoices and receipts issued to consumers.

Businesses with retail, hospitality, POS, e-commerce or other consumer-facing sales flows should ensure that those systems are included in their EBS implementation. A separate consumer-sales process that bypasses the MRA-compliant EBS can create a compliance gap.

E-Reporting and VAT Compliance in Mauritius

You can file periodic tax returns and make payments online through the Mauritius Revenue Authority e-Services Portal. 

The Mauritius Revenue Authority (MRA) manages periodic tax obligations for individuals and businesses according to specific monthly, quarterly, and annual timelines.

• Monthly: PAYE, CSG, VAT, and TDS returns are due by the end of the following month.
• Quarterly: Companies pay advance corporate tax (APS) within six months of the quarter's end.
• Annual: Individual income tax is due by October 15. Corporate tax is due within six months of the financial year-end.

Penalties for Non-Compliance

The consolidated VAT Act identifies distinct sanctions, including:

1. Failure to issue fiscal invoices under section 20A: MUR 10,000 for every month or part of a month, capped at MUR 200,000.
2. Failure to use a required electronic fiscal device or e-invoicing system: MUR 5,000 for every month or part of a month, capped at MUR 50,000.
3. Misuse of or tampering with the e-invoicing system: a penalty of up to MUR 50,000, with potential prosecution.
