In Malaysia, “e-invoice” and “tax invoice” are two separate documents under two different legal frameworks. A tax invoice is required for SST (Sales and Service Tax) compliance. An e-invoice issued under LHDN (Inland Revenue Board of Malaysia) is a separate digital record required under the Income Tax Act, validated through the MyInvois system. They do not replace each other. If your business is SST-registered and above the e-invoice revenue threshold, you need to issue both — for the same transaction.
One of the most common questions from Malaysian business owners in 2026 is whether LHDN’s new e-invoice requirement replaces their existing tax invoices. The short answer is no — they are entirely different documents under separate legal frameworks, serving different compliance purposes. Understanding the distinction is important because confusing them can lead to gaps in either SST compliance or LHDN e-invoice compliance. This guide explains exactly what each document is, how they differ, and what your business needs to issue.
What Is a Tax Invoice in Malaysia?
In Malaysia today, a “tax invoice” refers to an invoice issued under the Sales and Service Tax (SST) framework — governed by the Sales Tax Act 2018 and the Service Tax Act 2018. It is a document that SST-registered businesses issue to their customers, serving as the formal record of an SST-taxable transaction.
For service tax specifically, a tax invoice is important because it allows the recipient to verify the service tax component of a transaction. Businesses registered for SST are required to issue tax invoices for taxable supplies.
Not all businesses need to issue SST tax invoices. The requirement applies only to businesses that are registered for SST. Registration is triggered when taxable turnover crosses the applicable threshold set by the Royal Malaysian Customs Department (RMCD) — check the current threshold at customs.gov.my. Businesses below the SST registration threshold, or those in exempt categories, do not issue SST tax invoices.
Crucially, an SST tax invoice can be in paper, PDF, or any digital format — there is no specific digital validation requirement under the SST framework.
What Is an LHDN e-Invoice in Malaysia?
An LHDN e-invoice is a completely separate document — a digitally validated transaction record created and verified through LHDN’s MyInvois system. It is governed by the Income Tax Act 1967 (as amended) and LHDN’s e-Invoice Specific Guideline v4.6 (January 2026).
Unlike an SST tax invoice, which exists within the consumption tax framework, an LHDN e-invoice is primarily an income reporting and business transparency mechanism. Its purpose is to give LHDN a real-time, validated record of business transactions — reducing tax gaps and improving compliance visibility across the economy.
Every LHDN e-invoice must be:
- Submitted to LHDN’s MyInvois system for real-time validation before it is considered legally valid
- Returned with a unique QR code and Unique ID Number (UUID) from LHDN upon successful validation
- Issued within the applicable timeframe (real-time for individual invoices; within 7 calendar days after month-end for consolidated batches)
The e-invoice mandate applies to businesses above the revenue threshold — regardless of whether they are SST-registered. A non-SST business that earns RM2M per year is still mandated to issue LHDN e-invoices under Phase 4. For the full phase rollout timeline, read our LHDN e-invoice implementation update for 2026.
e-Invoice vs Tax Invoice: Key Differences
| Feature | SST Tax Invoice | LHDN e-Invoice |
|---|---|---|
| Legal basis | Sales Tax Act 2018 / Service Tax Act 2018 | Income Tax Act 1967 (as amended); e-Invoice Specific Guideline v4.6 |
| Governing authority | Royal Malaysian Customs Department (RMCD) | Inland Revenue Board of Malaysia (LHDN / IRBM) |
| Who must issue it? | Businesses registered for SST (Sales Tax or Service Tax) | All mandated businesses based on annual revenue threshold (Phase 1–4) |
| What is it for? | Evidences SST-taxable transactions; allows service tax verification | Real-time income reporting and digital business transparency to LHDN |
| Format requirement | Paper, PDF, or digital — no digital validation mandate | Must be validated digitally through LHDN’s MyInvois system |
| Validation required? | No — issued directly to customer | Yes — submitted to MyInvois, returns QR code + UUID before sharing with customer |
| Revenue threshold | SST registration threshold (separate for sales tax vs service tax) | RM1M–RM5M (Phase 4A); higher revenue = earlier phase |
| Related to consumption tax? | Yes — evidences SST-taxable supply | No — income/transparency mechanism, not a consumption tax document |
| Cancellation window | Per SST rules | 72 hours from LHDN validation |
Do You Still Need a Tax Invoice After Issuing an e-Invoice?
Yes — if your business is SST-registered. Issuing an LHDN e-invoice does not satisfy your SST tax invoice obligation, and vice versa. They are independent requirements under different laws.
For an SST-registered business that is also above the e-invoice revenue threshold, a single business transaction may require you to generate two separate documents:
- An SST tax invoice — issued to the customer as evidence of the SST-taxable supply, per RMCD requirements
- An LHDN e-invoice — validated through MyInvois and shared with the customer (with QR code), per LHDN requirements
In practice, many businesses generate both from the same underlying transaction data within their invoicing or accounting system. A well-configured middleware or accounting setup can produce the SST tax invoice as a PDF and simultaneously generate the LHDN e-invoice for MyInvois submission — without double-entry.

Which Businesses Must Issue e-Invoice vs Tax Invoice?
The two requirements are independent — your SST status does not determine your e-invoice obligation, and your e-invoice mandate does not determine your SST obligation. The matrix below shows the four possible combinations:
| Business Profile | SST Tax Invoice Required? | LHDN e-Invoice Required? |
|---|---|---|
| SST-registered AND above e-invoice threshold (e.g., service company, RM2M revenue) | ✅ Yes — for taxable supplies | ✅ Yes — Phase 4 mandated |
| SST-registered BUT below e-invoice threshold (e.g., service company, RM700K revenue) | ✅ Yes — for taxable supplies | ❌ Not yet mandated |
| NOT SST-registered AND above e-invoice threshold (e.g., exempt category business, RM3M revenue) | ❌ Not applicable | ✅ Yes — Phase 4 mandated |
| NOT SST-registered AND below e-invoice threshold (e.g., micro-business, RM400K revenue) | ❌ Not applicable | ❌ Not yet mandated |
The e-invoice revenue threshold for Phase 4A is RM1 million to RM5 million (FY2022 basis), mandatory from January 1, 2026. See our Phase 4 e-invoice SME guide for the full threshold and exemption details. For SST registration, consult the Royal Malaysian Customs Department at customs.gov.my.
How JomeInvoice Manages the Transition
For businesses navigating both SST tax invoice obligations and the new LHDN e-invoice mandate simultaneously, the operational challenge is real: two separate documents, two separate authorities, generated from the same transaction data.
JomeInvoice addresses the LHDN e-invoice side of this equation — the MyInvois integration, real-time validation, and consolidated vs individual e-invoice routing. It works alongside your existing accounting or billing system, which continues to generate your SST tax invoices as it always has.
Here is how the two systems coexist in a typical JomeInvoice deployment for SST-registered businesses:
- A transaction is processed in your accounting system (AutoCount, SQL, Xero, or similar)
- Your accounting system generates the SST tax invoice PDF as normal
- JomeInvoice receives the transaction data via API, generates the LHDN e-invoice, and submits it to MyInvois for real-time validation
- The validated e-invoice (with QR code and UUID) is returned to your system and shared with the customer
- Both documents — SST tax invoice and LHDN e-invoice — are on record for the same transaction
No double-entry. No replacing one system with another. JomeInvoice is purpose-built to be the LHDN compliance layer that sits alongside your existing invoicing workflow — not to replace it.

Frequently Asked Questions — e-Invoice vs Tax Invoice Malaysia
What is the difference between e-invoice and tax invoice in Malaysia?
A tax invoice in Malaysia is an SST (Sales and Service Tax) document governed by RMCD, required for SST-registered businesses. An LHDN e-invoice is a separate digital document governed by LHDN under the Income Tax Act, validated through the MyInvois system. They serve different purposes, have different governing bodies, and do not replace each other.
Do I still need to issue a tax invoice if I issue an e-invoice?
Yes — if your business is SST-registered. The LHDN e-invoice does not satisfy your SST tax invoice obligation. SST-registered businesses above the e-invoice revenue threshold must issue both: an SST tax invoice (for RMCD/SST compliance) and an LHDN e-invoice (for LHDN income reporting compliance) for taxable transactions.
Is an e-invoice the same as a GST tax invoice?
No. Malaysia’s GST was abolished in June 2018 and has not been reinstated. The LHDN e-invoice is a completely separate initiative under the Income Tax Act — it has nothing to do with GST. The current “tax invoice” in Malaysia refers to SST documents under the Sales Tax Act 2018 and Service Tax Act 2018.
Does LHDN e-invoice replace the SST tax invoice?
No. The LHDN e-invoice and SST tax invoice are independent documents under different laws (Income Tax Act vs Sales Tax/Service Tax Acts) and different authorities (LHDN vs RMCD). One does not replace the other. SST-registered businesses must continue issuing SST tax invoices regardless of their e-invoice mandate status.
Can I issue both a tax invoice and an e-invoice for the same transaction?
Yes — and for SST-registered businesses above the e-invoice threshold, you must. Both documents can be generated from the same transaction data. A well-configured accounting system or middleware solution can produce the SST tax invoice as a PDF and simultaneously generate the LHDN e-invoice for MyInvois submission without double-entry.
What happens to my existing tax invoices after e-invoice is mandated?
Your SST tax invoices continue as before — the e-invoice mandate does not change your SST obligations. You add the LHDN e-invoice process on top of your existing invoicing workflow. Your accounting software continues generating SST tax invoices; your e-invoice middleware handles the MyInvois submission in parallel.
Is e-invoice compulsory for non-SST businesses?
Yes — if they meet the revenue threshold. The LHDN e-invoice mandate is independent of SST status. A business earning RM2M per year that is not SST-registered is still mandated under Phase 4A from January 1, 2026. SST registration and e-invoice mandate are determined by separate thresholds under separate laws.
