LHDN E-Invoice Compliance: Common Mistakes to Avoid in 2025
Malaysia’s LHDN e-Invoice framework is transforming how businesses issue invoices, validate transactions, and report sales. But with this shift comes a learning curve — and making mistakes can delay your compliance or even lead to penalties.
If your business will soon need to submit invoices via MyInvois, here’s what you must avoid.
1. Missing the Mandatory Validation Step
An invoice is not considered valid until it’s submitted to MyInvois and receives a Unique Validation Code and QR code from LHDN.
Common error: Issuing a PDF invoice without MyInvois validation.
Solution: Always validate through the MyInvois portal or API before sending it to customers.
2. Incorrect Buyer Information
The buyer’s name, business registration number, and tax ID must exactly match LHDN records. Even small typos can trigger rejection.
Tip: Integrate your accounting system with a customer master database to reduce human error.
3. Wrong Invoice Type
The MyInvois system accepts different invoice types:
- Standard Tax Invoice
- Simplified Tax Invoice
- Credit/Debit Notes
Submitting the wrong type can cause rejection. Ensure your team understands when to use each format.
4. Poor File Formatting
Invoices must be in structured XML or JSON format, not just PDFs. Incorrect formatting or missing mandatory fields will lead to automatic rejection.
Tip: Use e-invoice-ready accounting software like AutoCount Cloud Accounting that formats your invoices correctly for MyInvois submission.
5. Late Submission
Deadlines matter. E-invoices must be submitted to MyInvois within 72 hours of issuance. Delays can result in non-compliance.
Solution: Automate submission through API integration to avoid manual delays.
6. Not Handling Buyer Rejections Properly
Buyers can reject an invoice through MyInvois within a specific window.
Mistake: Ignoring buyer rejection notifications.
Solution: Monitor your MyInvois dashboard daily and reissue corrected invoices promptly.
7. Forgetting to Sync with Your Accounting System
Even if you validate invoices in MyInvois, you still need to ensure they’re properly recorded in your accounting system.
Tip: Choose software that integrates both processes so there’s no data mismatch.
Bonus: How to Stay Compliant in 2025
- Train your staff on e-invoice requirements.
- Use integrated systems to reduce manual errors.
- Monitor LHDN updates — compliance rules may evolve.
- Work with an experienced e-invoice partner for setup and support.
