Malaysia’s tax authority, LHDN, is rolling out MyInvois, a nationwide e-Invoicing initiative aimed at improving transparency and reducing tax evasion. For SMEs, this means a mandatory shift from traditional invoicing to a digital-first, government-integrated platform.

This shift can feel overwhelming — especially with deadlines approaching fast. But the good news is, you can get MyInvois ready in just 7 days. This guide walks you through a simple, step-by-step roadmap to full compliance, even if you’ve never issued an e-Invoice before.

Day 1: Register with MyTax

Begin by logging into the MyTax portal using your company credentials. If you haven’t registered your business for online tax access, now’s the time to do so.

Once inside:

    • Apply for a user role — ideally, the “Company Director” role.
    • Approval typically takes 1–2 days. After that, you can delegate tasks to others in your organization.

Pro tip: Do this early to prevent bottlenecks later in the process.

Day 2: Set Up Your MyInvois Account

Once your role is approved, head to the MyInvois Portal. This is the system where you’ll issue, track, and manage e-Invoices going forward.

Here’s what to configure:

    • Your company profile (SSM number, business address, financial year, etc.)
    • Assign user roles for invoicing, reviewing, and validating
    • Set up notification preferences, such as email alerts for invoice status updates

📧 Tip: Use a dedicated email address just for MyInvois alerts. It’ll save you from missing critical notices.

Day 3: Choose a Compliant Software Provider

You can’t issue compliant e-Invoices manually at scale. Instead, you’ll need software that’s integrated with MyInvois via Peppol — a global standard used by the Malaysian government.

When choosing a provider, look for:

    • LHDN approval and a valid SPID
    • Seamless integration with MyInvois
    • Features like automated validation, status tracking, and error management
    • Local support in case you hit a snag

💡 Avoid solutions that feel overly complex or aren’t optimized for Malaysian SMEs. You’ll waste more time trying to make them work.

Day 4: Run a Few Test Invoices

Before going live, it’s smart to test the invoicing workflow.

Steps:

  1. Create a sample invoice in your new system
  2. Submit it to MyInvois for validation
  3. Confirm it receives a UIN (Unique Identification Number) from LHDN
  4. Review how errors are flagged and resolved

⚠️ Testing helps you catch setup issues before they affect real customers.

Day 5: Train Your Team

Don’t let your software do all the heavy lifting. Your team needs to understand how to:

    • Input data correctly
    • Review invoice statuses
    • Respond to LHDN rejections or issues

Even a short internal workshop can dramatically reduce mistakes later.

👥 Tip: Assign clear roles to avoid duplication or confusion.

Day 6: Monitor, Report, Improve

With everything in place, shift focus to monitoring and reporting.

What to track:

    • Invoice status: submitted, validated, rejected
    • Recurring errors and their causes
    • Monthly or quarterly reports to stay audit-ready

📊 Your invoicing tool should let you export these reports for compliance filings.

Day 7: Go Live with Confidence

It’s time to switch fully to e-Invoicing.

Double-check:

    • All roles are properly assigned
    • Your invoicing system is synced with MyInvois
    • Staff is confident in the new process

Now, begin sending e-Invoices for all transactions and monitor LHDN responses in real time.

🔁 Check for updates from LHDN regularly to stay aligned with any regulatory changes
