Where required by RSL
Lesotho has adopted the Value Added Tax (E-Invoicing) Regulations, 2026, establishing a structured VAT e-invoicing framework through the Invoice Data Management System (IDMS). The regulations entered into force on 1 April 2026 and allow Revenue Services Lesotho (RSL) to require VAT vendors to use Electronic Billing Systems (EBS) connected to IDMS.
Lesotho has a legally effective VAT e-invoicing framework, centred on the Lekuka Electronic Invoicing System, IDMS and EBS participation. Businesses need to determine whether and when RSL requires them to go live while continuing to meet ordinary VAT invoice, recordkeeping and periodic return obligations.
The most important e-invoicing development in Lesotho is the introduction of the Value Added Tax (E-Invoicing) Regulations, 2026, published on 27 March 2026. The National Assembly’s official committee report states that the regulations introduce the e-invoicing system known as the Invoice Data Management System (IDMS), which facilitates the exchange of invoice data.
On 27 June 2025, RSL introduced the Lekuka Electronic Invoicing System to business stakeholders. RSL states that Lekuka is intended to ease invoice reporting and VAT-return processes for businesses while giving the government improved data for economic analysis and evidence-based decision-making.
Tired of scrolling through information about e-invoicing?
In Lesotho, e-invoicing is being developed as part of VAT administration. The relevant infrastructure is IDMS, which facilitates the electronic exchange of invoice data, together with electronic billing systems that may be required to connect vendors to the framework.
RSL says the Lekuka system is intended to make invoice reporting and VAT-return processes easier for businesses. It is also designed to give government better transaction-level information for economic analysis and decision-making.
The policy direction is therefore focused on more reliable VAT invoice data, stronger transaction visibility, improved compliance monitoring, and less manual work when reconciling sales invoices and VAT reporting.
Lesotho’s e-invoicing journey is moving from traditional VAT invoice compliance toward a structured, RSL-led electronic invoicing framework.

Current Implementation of E-Invoicing in Lesotho
From 1 April 2026, the VAT e-invoicing framework is legally effective. It is built around IDMS and connected Electronic Billing Systems (EBS), through which RSL may require vendors to exchange structured VAT invoice data.
B2G structured e-invoicing falls within Lesotho’s VAT e-invoicing framework, where a government supplier is a VAT vendor required by RSL to use an EBS connected to the IDMS. The framework supports structured invoice-data exchange, rather than operating as a separate public-procurement e-invoicing network.
In-scope government suppliers must follow RSL’s EBS and IDMS procedures alongside applicable procurement and payment-documentation rules. No separate B2G format or rollout deadline has been confirmed.
B2B e-invoicing is mandatory for VAT vendors that RSL requires to use the Lekuka, IDMS and EBS framework. The Value Added Tax (E-Invoicing) Regulations, 2026, entered into force on 1 April 2026 and establish the legal basis for RSL to require in-scope vendors to exchange structured invoice data through an EBS connected to IDMS.
A conventional PDF invoice may not be sufficient where a B2B transaction must be issued through the IDMS/EBS framework. Businesses should verify their operational go-live date, onboarding steps, approved system requirements, invoice-data procedures and recordkeeping obligations against the latest RSL notice or taxpayer-specific instruction. The RSL Lekuka portal is also publicly available as the authority’s e-invoicing self-service platform.
B2C e-invoicing applies where RSL requires a VAT vendor to use an EBS connected to IDMS for consumer or retail transactions. The framework is not limited to B2B supplies and may support VAT transaction monitoring through structured invoice-data exchange.
In-scope businesses should not assume that a standard POS, handwritten, or PDF receipt meets the relevant requirements. E-invoicing and fiscalization are distinct, and RSL has not publicly confirmed specific rules for fiscal-device certification, consumer-receipt formats, or retail reporting; businesses should follow official RSL guidance as it becomes available.
Lesotho requires periodic VAT reporting. VAT-registered vendors must file a VAT return and pay any VAT due by the 20th day of the month following the month in which taxable supplies and input VAT arise. RSL also states that VAT is paid monthly by registered vendors.
VAT registration generally becomes compulsory where annual taxable turnover exceeds M2 million. VAT vendors should also continue to maintain valid VAT invoices, credit notes, debit notes, purchase records, and sales records.
Lesotho’s IDMS framework requires businesses to prepare for structured, invoice-level VAT compliance. Accurate invoice data and adaptable ERP, POS, accounting, marketplace, and billing systems will support readiness for RSL’s EBS and IDMS requirements.
