The first cross-border invoice is where most finance teams stall. MyInvois demands a Tax Identification Number for the other party, and a client in Singapore or a supplier in the UK has never heard of a Malaysian TIN. The instinct is to leave the field blank or skip the e-Invoice entirely. Both are wrong, and both are avoidable.

LHDN has published exactly what to enter. This guide walks through both directions of a cross-border transaction, the general TIN codes that replace a missing foreign TIN, and the deadlines that catch importers out.

Key Takeaways

• Direction decides the document. Selling to a foreign buyer means a normal e-Invoice. Buying from a foreign supplier means a self-billed e-Invoice you issue yourself.
• When a foreign buyer has no TIN, enter EI00000000020. When a foreign supplier has no TIN, enter EI00000000030.
• Any other missing field is filled with "NA", except the MSIC code, which takes "00000".
• Imported goods must be self-billed by the end of the second month after customs clearance; imported services by the end of the month following payment or the supplier's invoice, whichever is earlier.
• Failure to issue an e-Invoice is an offence under Section 120(1)(d) of the Income Tax Act 1967, carrying a fine of RM200 to RM20,000, up to six months' imprisonment, or both, for each non-compliance.

Which Direction Is the Transaction Going?

A cross-border transaction is any transaction between a Malaysian party and a party operating outside Malaysia, including a non-Malaysian individual. LHDN splits it into two flows, and each produces a different document (IRBM, e-Invoice Specific Guideline v4.8, Section 10).

How Do You Issue an e-Invoice to a Foreign Buyer?

You issue an ordinary e-Invoice, exactly as you would for a Malaysian customer, and substitute placeholder values where the foreign buyer's details do not exist. You are the Supplier; the foreign purchaser is the Buyer.

Three consequences follow from the foreign buyer sitting outside MyInvois. LHDN notifies only you once the document is validated. There is no rejection request, because the buyer has no portal account to raise one. And any error must therefore be corrected by issuing a credit note, debit note, or refund note e-Invoice rather than by cancellation after the fact.

Sharing the validated e-Invoice with your customer is business as usual rather than a legal duty, but most exporters attach the PDF visual representation to the shipping pack anyway.

How Do You Self-Bill a Foreign Supplier?

Because a foreign seller is not mandated to use MyInvois, the Malaysian purchaser assumes the role of Supplier and issues a self-billed e-Invoice to substantiate the expense for tax purposes. Pull the details off the foreign invoice, and where a detail is genuinely unavailable or not provided, LHDN's instruction is to enter "NA" — with two exceptions: the supplier's TIN becomes EI00000000030, and the supplier's MSIC code becomes "00000".

Two deadlines apply, and they differ:

• Imported goods — issue the self-billed e-Invoice by the end of the second month following the month customs clearance is obtained.
• Imported services — issue it by the end of the month following the month of payment or receipt of the supplier's invoice, whichever is earlier.

Where service tax on imported taxable services applies under the SST legislation, that service tax amount must be included in the self-billed e-Invoice. You are not obliged to share the validated document with the foreign seller; it exists as your proof of expense.

Recurring imports are where manual entry starts to break down, because the same supplier details have to be rekeyed every cycle. Mapping those records once inside a properly configured e-invoice system in Malaysia by Great CFO removes the repetition and the transcription errors that come with it.

What Exchange Rate Should You Use?

For a transaction billed in a currency other than Ringgit, the exchange rate follows a set order. Any legal or tax requirement imposed by an authority such as Royal Malaysian Customs or LHDN comes first. Where no such requirement applies, your own internal policy rate is acceptable. For self-billed e-Invoices covering the importation of goods, LHDN explicitly permits Malaysian taxpayers to use their internal exchange rate.

The rate belongs in the e-Invoice whenever the document has to be converted to a Ringgit equivalent, so record the policy you apply and stay consistent across periods.

What Happens If You Get a Cross-Border Document Wrong?

A validated e-Invoice can be cancelled by the supplier within 72 hours of validation, with justification. Miss that window and the only route is an adjustment document. Since a foreign counterparty cannot trigger a rejection, exporters and importers effectively have one self-imposed check: review before submission, not after.

The penalty for simply not issuing is real. LHDN's FAQs confirm that failure to issue an e-Invoice is an offence under Section 120(1)(d) of the Income Tax Act 1967, punishable by a fine of not less than RM200 and not more than RM20,000, imprisonment of up to six months, or both, for each non-compliance (IRBM, e-Invoice General FAQs).

There is breathing room for smaller businesses. Taxpayers in the phases with 1 January 2026 and 1 July 2026 implementation dates sit inside an interim relaxation period running until 31 December 2027, during which consolidated self-billed e-Invoices are permitted for every self-billed circumstance and no prosecution is pursued under Section 120, provided that consolidation route is followed. LHDN has also opened an e-Invoice Special Voluntary Disclosure Programme from 7 July 2026 to 31 December 2027 for taxpayers who missed submissions or filed them with errors.

Frequently Asked Questions

Does my foreign customer need to do anything in MyInvois?

No. Foreign parties are outside the system entirely. They receive no LHDN notification and cannot reject a document.

Can I skip the e-Invoice if my foreign supplier already gave me an invoice?

No. A foreign invoice alone does not substantiate the expense once you are mandated. The self-billed e-Invoice is the document LHDN recognises.

What if the foreign supplier does give me a TIN?

Use it. The general TIN codes are fallbacks for when a real TIN is unavailable or not provided.

Do I need a separate e-Invoice for each import shipment?

During the interim relaxation period applicable to your phase, consolidated self-billed e-Invoices are allowed. Outside it, follow the standard issuance rules.

Get the Direction Right First

Almost every cross-border e-Invoice error traces back to one question answered too quickly: who is the supplier here? Fix the direction, apply the right general TIN, and the remaining fields become mechanical.

Map your recurring foreign suppliers and export customers now, and decide which ones will be self-billed monthly before your relaxation period ends.
