LHDN MyInvois: the Malaysia e-invoicing guide for SMEs

The waves

How the rollout works

MyInvois is Malaysia's national e-invoicing system, operated by the tax authority LHDN. Instead of a plain PDF, your invoice is submitted to LHDN for validation, and a validated e-invoice is shared with your customer. See our MyInvois glossary entry for the short definition. The requirement is arriving by annual turnover band, largest businesses first.

Wave 1 Largest taxpayers.The highest turnover band was brought in first. In force
Mid waves Mid-sized businesses, by descending turnover band.Phased in on LHDN's published schedule. Rolling
Smaller SMEs Lower turnover bands, including many small businesses.Later waves, with grace periods as they begin. Approaching

Wave timing is set by LHDN and keyed to turnover bands. We keep this guide general because exact dates shift; confirm your band's date on the official LHDN schedule.

Are you in scope

Three situations, three answers

Act now Your turnover band's wave has started. Issuing validated e-invoices through MyInvois is required for you. Get your software submitting before your next billing cycle rather than after.
Prepare You are in a later wave. No date has bitten yet, but one is coming. Make sure your next accounting software decision already submits to MyInvois, so your wave is a settings change, not a migration.
Watch You are a very small or new business. Your band may be some way off, and grace periods usually apply at the start. Adopting early still helps if you invoice large customers that already run MyInvois.

How to comply

Getting compliant, in order

  1. Confirm your wave from your turnover

    Check your annual turnover against the current LHDN schedule to find when e-invoicing becomes mandatory for you. If LHDN has notified a date for your business, that date governs, whatever a general guide says.

  2. Pick software that submits to MyInvois

    The requirement runs through your accounting software, so this is where compliance is won or lost. Malaysia-built tools such as Financio put MyInvois front and centre; some regional tools connect through an integration or filing partner.

  3. Register and connect to LHDN

    Register your business on the MyInvois portal and connect your software to LHDN, typically through an API or your vendor's integration. This links your invoicing to the validation service.

  4. Submit a test e-invoice, then go live

    Issue one invoice through the system, confirm it is validated by LHDN and returned with its identifier, then switch real invoicing over. Keep a fallback for customers or documents that fall outside e-invoicing.

  5. Keep validated records and reconcile

    Store the validated e-invoices and their identifiers, and reconcile them against your books and SST reporting. Clean records make your tax filing and any LHDN queries straightforward.

FAQ

Questions businesses ask us

Is MyInvois mandatory in Malaysia?
Yes, in phases. LHDN is rolling e-invoicing out by business size, starting with the largest taxpayers and extending down to smaller businesses over time. As your turn arrives, issuing validated e-invoices through MyInvois becomes a requirement, so the practical question is whether your accounting software can submit for you.
What is the difference between MyInvois and InvoiceNow?
They are two separate national systems. MyInvois is Malaysia's e-invoicing regime, run by LHDN, where invoices are submitted for validation. InvoiceNow is Singapore's Peppol-based network. Complying with one does not cover the other, so a business operating in both countries needs software that handles each.
Do small businesses need to comply with MyInvois?
Eventually, yes, as the phased rollout reaches smaller turnover bands. Even before your band is mandatory you can adopt voluntarily. The low-cost move is to make sure your next accounting software choice already submits to MyInvois, so your wave is a settings change rather than a migration.
How do I submit e-invoices to MyInvois?
Either directly through the MyInvois portal for low volumes, or, more practically, through accounting software that connects to LHDN and submits for you. Tools built for Malaysia, such as Financio, put MyInvois handling front and centre.

I track the MyInvois rollout and the Malaysian accounting tools that submit to it, most recently in July 2026. Because LHDN's wave dates shift, this guide stays general on timing and is updated as the schedule changes.
