LHDN Malaysia e-Invoicing FAQs (2026): Basics to Advanced

Malaysia’s e-invoice exemption threshold is now RM3 million in annual turnover or revenue, set by the e-Invoice General Guideline v4.8 published on 30 August 2026 (previously RM1 million, from General Guideline v4.6 in December 2025 through v4.7). Phases 1 to 3 (above RM5 million) are under full enforcement, and the Phase 4 group (up to RM5 million) has been mandated since 1 January 2026. Businesses that started in 2023 to 2025 with RM3 million or more join on 1 July 2026, while businesses below RM3 million are exempt unless a shareholder, holding company or related company with at least RM3 million pulls them in. A relaxation period runs for the up-to-RM5-million group until 31 December 2027, with full enforcement from 1 January 2028. [e-Invoice General Guideline v4.8, §1.5, §1.6.1(e), §1.6.10; e-Invoice Specific Guideline v4.8, Table 16.1]

Every answer below was verified against the e-Invoice Specific Guideline v4.8 (7 July 2026) and the e-Invoice General Guideline v4.8 (30 August 2026), plus the LHDN e-Invoice General FAQs (5 January 2026, which still show the superseded RM1 million figures). The RM3 million threshold statements are based on the guideline text itself; as at 30 August 2026 LHDN has not issued a media release or FAQ update on the change. Where the Inland Revenue Board of Malaysia (Lembaga Hasil Dalam Negeri, LHDN, also known as IRBM) has changed a rule since this page was first published in October 2024, the answer has been rewritten, not patched.

This FAQ hub follows LHDN’s own FAQ structure: general questions, scope and process, Micro, Small and Medium Enterprises (MSMEs), the relaxation period, the new Special Voluntary Disclosure Programme (SVDP), and advanced MyInvois Portal and API questions. For the full narrative, start with our complete LHDN e-invoice guide for Malaysia 2026.

Part 1: Malaysia e-invoicing FAQs: General

Introduction to e-invoice

1. What is an e-invoice, and what formats does IRBM accept?

An e-invoice is a machine-readable digital record of a transaction between a supplier and a buyer, structured in XML or JSON according to the schema in the e-Invoice Software Development Kit (SDK) at sdk.myinvois.hasil.gov.my. A PDF, scanned image or paper invoice is not an e-invoice. Once validated by IRBM, it carries an IRBM Unique Identifier Number and a QR code. [LHDN e-Invoice General FAQs, Q1–Q2, Q36–Q37]

2. How are e-invoices transmitted to IRBM?

There are two transmission mechanisms: the MyInvois Portal (manual or spreadsheet upload) and the Application Programming Interface (API), used directly or through a middleware provider. A taxpayer may use both, provided the same e-invoice is not submitted twice. [LHDN e-Invoice General FAQs, Q3, Q113] IRBM validates each e-invoice before it is shared with the buyer [e-Invoice General Guideline v4.8, §2.1–2.3]; the industry term for this is a Continuous Transaction Control (CTC) model. The options are compared in our guide to e-invoice integration models in Malaysia.

Applicability of LHDN e-invoice Implementation in Malaysia

3. Is e-invoice applicable only within Malaysia?

No. E-invoicing applies to both domestic and cross-border transactions. For imports, the Malaysian buyer issues a self-billed e-invoice; for exports, the Malaysian supplier issues a normal e-invoice to the foreign buyer. [LHDN e-Invoice General FAQs, Q5; e-Invoice Specific Guideline v4.8, Section 10]

4. Are all businesses required to issue e-invoices?

All taxpayers undertaking commercial activities in Malaysia fall within the e-invoice framework and are phased in by annual turnover or revenue, with an exemption for taxpayers below RM3 million (subject to the related-party caveat in Q6 and Part 3). [LHDN e-Invoice General FAQs, Q6; e-Invoice General Guideline v4.8, §1.6.1(e)]

5. Are there any exemptions for industries?

No industry is exempt from e-invoice implementation. Certain persons and certain types of income and expense are exempt under Section 1.6 of the e-Invoice General Guideline, and exempt taxpayers are not required to issue consolidated or self-billed e-invoices either. Statutory bodies, statutory authorities, local authorities and international organisations are required to implement e-invoice from 1 July 2025 for goods sold or services performed. [e-Invoice General Guideline v4.8, §1.6.1, §1.6.2, §1.6.9; LHDN e-Invoice General FAQs, Q7, Q95]

6. Threshold for Malaysia e-invoice Implementation

Taxpayers with annual turnover or revenue of less than RM3 million are exempt from mandatory e-invoice issuance unless a non-individual shareholder, holding company, related company or joint venture partner with turnover of at least RM3 million pulls them in; the caveats are set out in Part 3. The RM1 million threshold applied from December 2025 (General Guideline v4.6) until 29 August 2026 (last carried in v4.7). [e-Invoice General Guideline v4.8, §1.6.1(e), §1.6.10]

Implementation timeline by revenue phase (FY2022 basis for businesses operating before 2023):

Source: e-Invoice General Guideline v4.8 (30 August 2026), Table 1.1 and §1.5; e-Invoice Specific Guideline v4.8, Table 16.1. Relaxation and enforcement dates for each band are in Part 4.

Implementation based on operation start date and revenue changes:

• Started in 2023 to 2025 with annual turnover or revenue of at least RM3 million: e-invoice from 1 July 2026. [e-Invoice General Guideline v4.8, §1.5]
• Started in 2026 onwards: e-invoice from 1 July 2026 or the commencement date; if first-year turnover is expected to be less than RM3 million, from 1 January of the second year after the year in which turnover reached RM3 million. [e-Invoice General Guideline v4.8, §1.5]
• Established businesses that later reach RM3 million: the second-year rule applies; see Part 3.

Historical note: the exemption threshold was first set at RM150,000, raised to RM500,000, revised to RM1 million in December 2025 (General Guideline v4.6, carried in v4.7) and raised again to RM3 million by General Guideline v4.8 on 30 August 2026. Any page still quoting RM500,000 or RM1 million is out of date. For the running changelog of every LHDN revision, see our LHDN e-invoice implementation update, and for the extension mechanics see the Phase 4 extension to 2028 guide.

Available e-invoicing Support and Assistance in Malaysia

7. Who do I contact for e-invoice queries?

Four official channels exist. [LHDN e-Invoice General FAQs, Q16]

• Email for implementation questions: [email protected]
• MyInvois Customer Feedback Form for SDK and technical enquiries
• e-Invois HASiL Help Desk Line: 03-8682 8000, 24 hours a day, Monday to Sunday
• MyInvois Live Chat, available from the e-Invoice contact page on hasil.gov.my

8. Are there any incentives for implementing e-invoicing?

Yes. Budget 2024 introduced a tax deduction of up to RM50,000 per year of assessment on environmental, social and governance (ESG) related expenditure, including e-invoice consultation fees, for MSMEs, effective YA2024 to YA2027. [LHDN e-Invoice General FAQs, Q17] How to claim it is covered in our ESG tax deduction for e-invoice guide.

LHDN e-invoicing compliance rates and enforcement

9. How many businesses are already on e-invoice, and is LHDN enforcing?

By April 2026, 225,604 taxpayers had submitted 1.299 billion e-invoices since 1 August 2024. During the National e-Invoice Compliance Review Operation on 20 to 24 April 2026, LHDN cited 108 Phase 1 and Phase 2 taxpayers for non-implementation, and its reviews had by then uncovered RM3.5 billion in unreported income, as reported by Free Malaysia Today on 27 April 2026 (accessed 30 August 2026). [LHDN National e-Invoice Compliance Review Operation, 20–24 April 2026]

10. What does non-compliance cost?

Failure to issue an e-invoice is an offence under Section 120(1)(d) of the Income Tax Act 1967: a fine of RM200 to RM20,000, imprisonment of up to six months, or both, for each e-invoice. LHDN’s compliance reviews cover up to two years of assessment, with a 12-year prosecution window. [LHDN e-Invoice General FAQs, Q33; Compliance Review Framework, 15 December 2025, Section 4] The full picture is in our LHDN e-invoice penalty guide.

Part 2: Malaysia e-invoicing FAQs: Scope and Process

General Malaysia e-invoicing Process

11. Must foreign-currency transactions be converted to Ringgit Malaysia?

No. An e-invoice may be issued in any currency. The RM equivalent is only required where a legal or tax requirement calls for it. [LHDN e-Invoice General FAQs, Q18; e-Invoice Specific Guideline v4.8, Section 13]

12. Can I issue a self-billed e-invoice if my supplier does not issue one?

No. Self-billed e-invoices are permitted only for the nine scenarios in Section 8.3 of the Specific Guideline, such as payments to agents, dealers and distributors, foreign suppliers, individuals not conducting a business and e-commerce platform payouts. [LHDN e-Invoice General FAQs, Q20–Q21; e-Invoice Specific Guideline v4.8, Section 8.3] All nine are walked through in our self-billed e-invoice guide.

Details of Supplier and Buyer in Issuing e-invoice

13. What buyer details are needed to issue an e-invoice?

Buyers must give the supplier the details required by the Specific Guideline: name, Tax Identification Number (TIN), registration or identification number, address and contact details. The split of duties between the two parties is explained in our e-invoicing guidelines for seller and buyer. [LHDN e-Invoice General FAQs, Q23]

14. What TIN do individual buyers use?

Individual taxpayers provide a TIN with the prefix “IG”. For Malaysian individuals the supplier may alternatively use the MyKad or MyTentera number, or both. [LHDN e-Invoice General FAQs, Q24; e-Invoice Specific Guideline v4.8, Section 3.5.4]

15. How do I issue an e-invoice to a buyer without a TIN, such as a foreign buyer?

Use the general TIN EI00000000020 for foreign buyers without a Malaysian TIN; EI00000000010 covers the general public in consolidated B2C e-invoices, EI00000000030 foreign suppliers in self-billed e-invoices, and EI00000000040 government bodies. [LHDN e-Invoice General FAQs, Q25–Q27; e-Invoice Specific Guideline v4.8, Appendix 1] For foreign suppliers, it is the taxpayer’s responsibility to check whether the supplier already holds a specific LHDN-assigned TIN before defaulting to EI00000000030. [LHDN e-Invoice General FAQs, Q27] See our TIN code reference.

16. Which business registration number goes on the e-invoice?

Taxpayers registered with the Companies Commission of Malaysia (SSM) must use the new 12-digit business registration number (BRN). Because many taxpayers could not obtain it in time, IRBM temporarily disabled the registration-number validation from 19 July 2024. Taxpayers not registered with SSM enter the registration number issued by the relevant authority or body. [LHDN e-Invoice General FAQs, Q28–Q29] For the 2026 position on TIN and BRN checks, read our TIN and BRN validation update.

Issuance of e-invoices

17. When must an e-invoice be issued?

There is no general same-day requirement. Deadlines apply only to consolidated e-invoices (seven calendar days after month-end), imported goods (end of the second month after customs clearance), imported services (end of the month after payment or foreign invoice, whichever is earlier) and foreign income (end of the month after receipt). Imports cleared, paid for or invoiced before the taxpayer’s mandatory implementation date need no self-billed e-invoice. [LHDN e-Invoice General FAQs, Q30, Q107, Q109] Our transaction types and timelines guide tabulates each one.

18. Can I issue a consolidated e-invoice for buyers who do not need an e-invoice?

Yes, for B2B, B2C and B2G transactions where the buyer has not requested an individual e-invoice, except for the activities listed in Section 3.7 of the Specific Guideline and any single transaction above RM10,000. [LHDN e-Invoice General FAQs, Q31; e-Invoice Specific Guideline v4.8, Table 3.6] Formatting rules are in our consolidated e-invoice FAQ.

19. Can I save draft e-invoices in the MyInvois Portal?

Yes. Suppliers can create e-invoices in draft or proforma form; the e-invoice is only accepted once validation succeeds. [LHDN e-Invoice General FAQs, Q32] Practise in the sandbox first using our MyInvois Portal testing environment walkthrough.

20. What happens if I fail to issue an e-invoice?

See Q10 above: a fine of RM200 to RM20,000 per e-invoice, imprisonment of up to six months, or both, under Section 120(1)(d) of the Income Tax Act 1967. [LHDN e-Invoice General FAQs, Q33]

Validation of e-invoices

21. How long does validation take, and what does IRBM validate?

IRBM validates in near real-time, generally in under two seconds. [LHDN e-Invoice General FAQs, Q34; e-Invoice Specific Guideline v4.8, Section 3.8] Format and data-structure checks: mandatory fields present, codes valid, TIN structure correct, totals consistent and no duplicate submission. The rules are published in the SDK and its MyInvois SDK FAQ. [LHDN e-Invoice General FAQs, Q35]

22. Does IRBM replace my invoice number?

No. The supplier’s invoice number stays in the document as a separate field for internal tracking. IRBM adds its own IRBM Unique Identifier Number to each validated e-invoice. [LHDN e-Invoice General FAQs, Q36]

23. What changes in MyInvois validation on 23 October 2026?

Two new validation rules take effect in the Production environment on 23 October 2026, announced in the SDK Updates of 6 August 2026. [MyInvois SDK Release Notes]

• All monetary amount fields, at invoice level and line level, are capped at a maximum length of 26 digits.
• The ID Type PASSPORT is limited to 12 characters.

Submissions that breach either rule may be rejected, so field lengths should be audited before that date. Separately, the SDK documentation of 17 July 2026 clarified that on tax-exempt transactions the TaxAmount element need not be 0.00.

Sharing of e-invoices

24. How must I share a validated e-invoice with the buyer?

Until further notice, suppliers may share the validated XML or JSON file, a visual representation of it, or both. There is no standard template: any visual format may be used, provided the QR code generated on validation is embedded, and any camera or scanner app can read it. Consolidated e-invoices do not need to be shared with buyers. [LHDN e-Invoice General FAQs, Q37–Q38, Q111, Q121]

Adjustments to e-invoices

25. Can I edit an e-invoice after validation?

No. A validated e-invoice cannot be edited. The supplier has 72 hours from the time of IRBM validation to cancel it and issue a corrected e-invoice; alternatively, a credit, debit or refund note e-invoice may be issued even inside the 72 hours. Once the window closes, the e-invoice stands and any change must go through an adjustment document. [LHDN e-Invoice General FAQs, Q39–Q42]

26. How do I correct a mistake found after 72 hours?

Issue a credit note, debit note or refund note e-invoice that quotes the IRBM Unique Identifier Number of the original in the “Original e-Invoice Reference Number” field. If the original was a pre-e-invoice document with no identifier, enter “NA”. [LHDN e-Invoice General FAQs, Q43, Q45]

27. Is there a time limit for issuing adjustment e-invoices?

No. LHDN sets no time restriction on issuing a credit, debit or refund note after the 72-hour window has passed; taxpayers follow their own commercial policy. [LHDN e-Invoice General FAQs, Q44]

28. Can one credit note adjust several original e-invoices?

Yes. A single credit, debit or refund note e-invoice may adjust multiple original e-invoices, including consolidated ones, as long as each original identifier is listed. [LHDN e-Invoice General FAQs, Q45]

29. Do I need a refund note e-invoice to return money to a buyer?

Yes, except for money paid wrongly by the buyer, overpayments and the return of security deposits. [LHDN e-Invoice General FAQs, Q46]

Part 3: Malaysia e-invoicing FAQs for MSMEs

30. What changed in General Guideline v4.8 (30 August 2026)?

General Guideline v4.8 replaces v4.7 (7 July 2026) and raises the MSME exemption threshold from RM1 million to RM3 million, with matching changes to the related-party carve-outs and the new-business rule; §1.6.9 adds that statutory bodies, statutory authorities, local authorities and international organisations are on e-invoice from 1 July 2025. Table 1.1 phase dates, the relaxation to 31 December 2027, the SVDP and the 23 October 2026 SDK change are unchanged. [e-Invoice General Guideline v4.8, Summary of Changes]

31. Which MSMEs are exempt from e-invoice?

MSMEs with annual turnover or revenue of less than RM3 million are exempt from issuing e-invoices, including consolidated and self-billed e-invoices; previously the line was RM1 million under v4.7. At RM3 million or more, e-invoice is mandatory. [e-Invoice General Guideline v4.8, §1.6.1(e), §1.6.2; LHDN e-Invoice General FAQs, Q95] Full detail sits in our e-invoice SME exemption guide.

32. Does the exemption apply to all MSMEs?

The exemption applies to all categories of taxpayers (individuals, partnerships, companies, co-operatives and others) below RM3 million, except a taxpayer with non-individual shareholders with annual turnover or revenue of at least RM3 million, a subsidiary of a holding company with at least RM3 million, or a related company or joint venture with at least RM3 million. Those taxpayers must implement e-invoice from 1 July 2026 regardless of their own revenue. “Related company” has the meaning in Section 2 of the Promotion of Investments Act 1986. [e-Invoice General Guideline v4.8, §1.6.10; LHDN e-Invoice General FAQs, Q90] Worked examples are in our related company e-invoice FAQ.

33. When must an MSME that crosses RM3 million start?

From 1 January of the second year after the year in which turnover reached RM3 million, so a business that crosses RM3 million during 2026 starts on 1 January 2028. General Guideline v4.8 states this rule for businesses started in 2026 onwards (§1.5); LHDN’s FAQs apply the same second-year rule to established MSMEs, using the earlier RM1 million figure. [e-Invoice General Guideline v4.8, §1.5; LHDN e-Invoice General FAQs, Q91]

34. How is annual turnover measured for the RM3 million test?

From the statement of comprehensive income in the audited financial statements for the relevant year, or, where there is no audit, from the annual revenue reported in the tax return for that year of assessment. [LHDN e-Invoice General FAQs, Q92]

35. How does the threshold work for a sole proprietor with several businesses?

All sole proprietorship businesses registered under the same individual are aggregated and the total is tested against RM3 million. LHDN’s FAQ example (three businesses earning RM200,000, RM550,000 and RM280,000, total RM1,030,000) was written for the earlier RM1 million threshold; under v4.8 that owner would be below RM3 million and exempt. [LHDN e-Invoice General FAQs, Q93; e-Invoice General Guideline v4.8, §1.6.1(e)]

36. If turnover later drops below RM3 million, is the exemption restored?

No, as a principle: once a taxpayer’s implementation timeline has been determined, later changes in turnover do not change the obligation. LHDN has not yet clarified whether businesses in the RM1 million to RM3 million band that already implemented e-invoice under v4.7 are released by the new threshold. [e-Invoice General Guideline v4.8, §1.5; LHDN e-Invoice General FAQs, Q94]

37. Does an exempt MSME have to do anything for platform sales, or when a large customer asks for e-invoices?

For Shopee, Lazada or similar platforms, the MSME must give its details to the platform; the platform issues the e-invoice or self-billed e-invoice for platform sales, while own-store sales remain the MSME’s responsibility once mandated. A mandated buyer cannot compel an exempt or pre-mandate MSME to issue e-invoices; voluntary early adoption is welcomed and the MyInvois Portal and mobile app are free. [LHDN e-Invoice General FAQs, Q96–Q97, Q100–Q102]

38. How does an MSME issue consolidated e-invoices if it does not issue receipts?

Businesses with annual gross takings above RM150,000 (goods) or RM100,000 (services) must already issue serially numbered receipts under Section 82(1)(b) of the Income Tax Act 1967, and those receipt numbers go into the consolidated e-invoice. This receipt duty is not an e-invoice threshold; the e-invoice exemption is RM3 million. [Income Tax Act 1967, s.82(1)(b); summarised in LHDN e-Invoice General FAQs, Q98–Q99]

Part 4: e-invoice Treatment During Interim Relaxation Period

39. Who is in a relaxation period in 2026 to 2027?

Only taxpayers with annual turnover or revenue of up to RM5 million (effectively RM3 million to RM5 million after the v4.8 exemption): those mandated on 1 January 2026 and those mandated on 1 July 2026. Their relaxation runs until 31 December 2027, with full enforcement from 1 January 2028. The six-month relaxation periods for Phases 1 to 3 ended on 31 January 2025, 30 June 2025 and 31 December 2025 respectively, and those taxpayers are under full enforcement. [e-Invoice Specific Guideline v4.8, Table 16.1; LHDN e-Invoice General FAQs, Q103]

Source: e-Invoice Specific Guideline v4.8, Table 16.1 (as amended April 2026).

For the record, the Income Tax (Issuance of Electronic Invoice) Rules 2024 [P.U. (A) 265] did not move the Phase 1 dates; the change that matters is the April 2026 decision that moved the up-to-RM5-million relaxation end from 31 December 2026 to 31 December 2027. [LHDN e-Invoice General FAQs, Q103–Q104]

40. What may a taxpayer do during the relaxation period?

Section 16.2 of the Specific Guideline allows four concessions. [e-Invoice Specific Guideline v4.8, Section 16.2]

1. Issue consolidated e-invoices for all activities and transactions, including those listed in Section 3.7.
2. Issue consolidated self-billed e-invoices for all Section 8.3 scenarios.
3. Enter any description in the “Description of Product or Service” field, not only receipt or statement references.
4. Decline a buyer’s (or, for self-billing, a supplier’s) request for an individual e-invoice, provided items 1 and 2 are followed.

Taxpayers who comply with items 1 and 2 face no prosecution under Section 120 of the Income Tax Act 1967. [e-Invoice Specific Guideline v4.8, Section 16.3] Our comparison of implementation with and without the grace period sets the two regimes side by side.

Read the RM10,000 e-invoice rule explainer before relying on consolidation.

41. Is the relaxation period mandatory?

No. It exists for taxpayers whose systems are not yet ready. A taxpayer that can issue individual e-invoices may do so from day one and ignore the concessions. [LHDN e-Invoice General FAQs, Q105]

42. Do I still submit monthly during the relaxation period?

Yes. Consolidated e-invoices and consolidated self-billed e-invoices must be submitted monthly, within seven calendar days after month-end, not once at the end of the relaxation period. [LHDN e-Invoice General FAQs, Q106; e-Invoice Specific Guideline v4.8, Sections 3.6.2 and 3.6.6]

e-Invoice Special Voluntary Disclosure Programme (SVDP) FAQs

43. What is the e-Invoice SVDP?

The e-Invoice Special Voluntary Disclosure Programme is an amnesty introduced in Section 17 of Specific Guideline v4.8 that lets taxpayers regularise past e-invoice non-compliance by submitting the e-invoices they missed or filed incorrectly. It runs from 7 July 2026 to 31 December 2027. [e-Invoice Specific Guideline v4.8, Section 17]

44. Who can use the SVDP, and what relief does it give?

Taxpayers who missed submissions, submitted erroneous e-invoices or never submitted anything, and even taxpayers already under, or notified of, a compliance review. Relief is no compliance review, no penalties and no prosecution on the disclosed e-invoices, provided the taxpayer acts in good faith; it is withdrawn where the disclosure involves fraud, wilful default or negligence, or where the SVDP submissions themselves fail the prescribed specifications. [e-Invoice Specific Guideline v4.8, Sections 17.1–17.4]

45. How are SVDP e-invoices submitted?

Use the e-invoice version tag SVDP 1.2 (without digital signature) or SVDP 1.3 (with digital signature); these tags must not be used for normal submissions. Back-filing must be one consolidated e-invoice per month of transaction, never a lump sum across months, and any single transaction above RM10,000 must still be back-filed as an individual e-invoice. [e-Invoice Specific Guideline v4.8, Sections 17.5–17.6, Examples 23–24]

MyInvois Portal: Advanced e-invoicing FAQs

46. What should I do about Error 400 (BadArgument) during TIN validation?

The TIN or another input parameter does not match the expected structure. Check the TIN format (for example the “IG” prefix for individuals, or the general TIN codes) before resubmitting. [MyInvois SDK FAQ] Our guide on how to check a TIN on MyTax shows the manual route.

47. What do Error 401 (Unauthorized) and Error 429 (Too many requests) mean?

Error 401 means the access token has expired; tokens are valid for one hour, so generate a new one with the “Login as Taxpayer” or “Login as Intermediary” API. Error 429 means the integration exceeded the API rate limit; pause briefly and retry, and build back-off logic into production integrations. [MyInvois SDK FAQ]

48. Are negative values allowed, and is there a limit on buyer email addresses?

Yes, negative values are allowed for fields within Document Submission. The email field accepts a single address of up to 320 characters in valid RFC 5321/5322 format with no spaces. [MyInvois SDK FAQ]

49. What are the submission size limits, and how do I shrink an XML file over 300KB?

Each submission may contain up to 100 e-invoices and 5MB in total, with each e-invoice capped at 300KB. If a document exceeds 300KB, minify it: strip whitespace, comments and formatting without changing content. [LHDN e-Invoice General FAQs, Q114; MyInvois SDK FAQ]

50. How does MyInvois detect duplicate e-invoices?

MyInvois compares, using the AND operator, the e-invoice type and version, the issuance date and time, the internal ID or invoice number, and the supplier TIN (or buyer TIN for self-billed e-invoices). A match on all fields is flagged as a duplicate. [MyInvois SDK FAQ]

51. What happens if the MyInvois System goes down?

LHDN targets 99.97% availability. If the system is unavailable, suppliers have 72 hours after it returns to issue their e-invoices, and API integrations should include a retry mechanism. [LHDN e-Invoice General FAQs, Q122]

Wrapping Up Malaysia e-invoicing Process

The up-to-RM5-million group is inside its relaxation window until 31 December 2027, the SVDP gives late filers a penalty-free route to catch up, and the two dates to plan around are 23 October 2026 (MyInvois validation change) and 1 January 2028 (full enforcement). Always check myinvois.hasil.gov.my and the SDK microsite for newer versions before relying on any single answer above.

How JomeInvoice Helps You Put These Answers Into Practice

Most of the questions above are rules your invoicing system must apply on every transaction: the RM10,000 split, the seven-day consolidated deadline, the 72-hour window, general TIN codes, field lengths.

Frequently Asked Questions

Is e-invoice mandatory for all businesses in Malaysia?

No. Businesses with turnover or revenue of less than RM3 million are exempt under General Guideline v4.8, unless a shareholder, holding company, related company or joint venture partner has turnover of at least RM3 million.

What is the e-invoice threshold in Malaysia in 2026?

RM3 million in annual turnover or revenue, raised from RM1 million by the General Guideline v4.8. A business that reaches RM3 million in 2026 implements e-invoice from 1 January of the second year after that year, so 1 January 2028. [e-Invoice General Guideline v4.8, §1.5, §1.6.1(e)]
