What is expense reimbursement? A guide for Malaysian businesses (2026)

Key takeaways:

• Expense reimbursement is how your company pays an employee back for a business cost they paid from their own pocket, matched to a receipt.

• In Malaysia, the tax treatment depends on whether you reimburse an actual cost or pay a fixed allowance — and LHDN, SST and MyInvois rules all shape what's deductible and what isn't.

• With Airwallex Expense Management, your team can submit, approve and reimburse claims in MYR same-day through DuitNow or IBG, without exporting files to your bank.

What is expense reimbursement? It’s how your business pays employees back for costs they covered out of pocket while doing their job.

It sounds simple, but getting it right in Malaysia means handling LHDN rules, SST treatment, MyInvois requirements and the speed of your payout rails — all at the same time.

This guide explains what expense reimbursement is, how the process works, which expenses qualify, and which Malaysian tax and e-invoicing rules apply. You'll also see how same-day MYR payouts can change how your team feels about claims week to week.

What is expense reimbursement?

Expense reimbursement is the payment a company makes to an employee to cover a business expense the employee has already paid for. The amount should match the receipt exactly — no markup, no rounding up, no "near enough" figures.

How expense reimbursement works

The employee pays first, usually with their personal card or cash. They keep the receipt, log the expense, and submit a claim to the company. A manager checks the claim against policy. Finance reviews it for documentation and tax treatment, then pays the employee back.

Common examples include a client lunch in KLCC, a Grab ride to a customer meeting in Petaling Jaya, an overnight stay in Johor Bahru for a site visit, or a training course an employee pays for upfront.

When the process works well, the employee is paid back within days, the receipt is filed against the right expense category in your books, and the cost flows cleanly into your management accounts and tax return.

Reimbursement vs company card spending

Reimbursement is one way to fund business spend. Company cards are the other.

With reimbursement, the employee fronts the cost and waits to be repaid. With a company card — a corporate card or virtual card issued in your business's name — the company funds the spend directly. The receipt still needs to be captured for tax and audit, but no one is out of pocket.

For one-off purchases or staff who rarely spend on the company's behalf, reimbursement is usually fine. For sales teams, ad spend, or anyone making frequent purchases, company cards are faster and less stressful for everyone. Most Malaysian businesses use a mix of both.

Reimbursement vs disbursement

These two terms are often confused, especially since MyInvois went live. The distinction matters for tax and e-invoice treatment.

A reimbursement is when your company recovers a cost it incurred as the principal — for example, an employee buys office supplies for the team and the company pays them back. The cost belongs to the company.

A disbursement is when your company pays a third party on behalf of someone else — for example, a marketing agency books a venue in a client's name and recovers the exact amount from the client. The cost belongs to the client; your company is just the agent.

Reimbursements may be subject to SST if part of a taxable service. Disbursements are not, provided strict conditions are met. We'll cover the tax treatment in detail later in this guide.

The expense reimbursement process

Most Malaysian businesses follow a three-step flow. The mechanics vary by company size and software, but the principle is the same: the employee documents the spend, someone reviews it, and finance pays it back.

Step 1: Employee submits the claim

The employee pays for the expense out of pocket, then gathers the receipt or tax invoice. They record the details — vendor, date, amount, business purpose and category — and attach the receipt to a claim form, an HR portal, or an expense app.

A few details matter in Malaysia. The receipt needs to show the vendor's name and the date, and ideally the SST registration number if SST applies. For larger purchases from a vendor that issues e-invoices through MyInvois, the validated e-invoice is the document your finance team will want, not a thermal-paper receipt.

For mileage claims, the employee should log the trip purpose, start point, end point and distance. A blanket monthly figure with no logs is treated very differently by LHDN than a documented per-kilometre claim.

Step 2: Manager and finance approval

The line manager reviews the claim against your expense policy. Is the spend within the daily meal cap? Did the employee book economy class as required? Is the client name on the entertainment claim a real customer?

Finance then checks the tax treatment and documentation. They confirm the receipt is original, the category is correct, and the SST treatment is right — for example, that an entertainment claim has been flagged for the 50% deductibility rule.

The most common reasons claims get rejected: missing receipts, personal items mixed in with business spend, amounts above policy limits, and claims submitted past the deadline (typically 30 to 60 days after the spend).

Step 3: Payment and record-keeping

Once approved, finance pays the employee back. Most Malaysian businesses pay through bank transfer — either a one-off IBG transfer or a DuitNow payment using the employee's mobile number or NRIC. Some companies bundle reimbursements into payroll, which is administratively simpler but slows the payout by days or weeks.

The expense is then recorded in your accounting system against the right category — travel, meals, training, or whatever applies. LHDN expects you to keep supporting documents for seven years in case of audit, so the receipts and approval trail need to be stored somewhere retrievable, not stuffed in a manila folder on someone's desk.

Types of reimbursable expenses in Malaysia

Not every cost an employee pays for is reimbursable. The general test, both for policy and for LHDN purposes, is whether the expense was incurred wholly and exclusively in the production of business income. Beyond that, your policy decides what's in and what's out.

These are the categories that come up most often for Malaysian businesses:

Category 1: Business travel and accommodation

This covers flights, KTM tickets, Grab rides, hotels, and short-term accommodation booked through platforms like Agoda. The receipt usually doubles as a tax invoice. For overseas trips, employees should also keep boarding passes and hotel folios in case of audit.

Category 2: Meals and per diem

Meal claims fall into two patterns: actual reimbursement against a receipt, or a fixed per diem. Actual reimbursement is cleaner for tax. A per diem is simpler operationally but the LHDN treatment depends on whether the daily rate is reasonable and consistent across staff at the same grade.

Category 3: Mileage and petrol

When an employee uses their personal car for business, the company usually reimburses by the kilometre. A typical rate is RM0.70 to RM0.90 per kilometre, though this varies by company. A trip log — date, start, destination, purpose, distance — is essential. Without it, the payment can be reclassified as a taxable allowance.

Category 4: Client entertainment

Client entertainment covers meals, drinks, golf, and event tickets where the purpose is to build or maintain a customer relationship. Require the employee to log the client's name, company, and business purpose on the claim — this is the category most often abused. Note the tax treatment under the 50% rule, covered in the next section.

Category 5: Office supplies, tools and professional development

The catch-all category — stationery, software subscriptions, dongles, course fees. Same test as any other expense: business purpose, supported by a receipt, within your policy limits. For larger one-off purchases, most companies require pre-approval rather than after-the-fact reimbursement.

5 Malaysian tax rules every finance team needs to know

This is where reimbursement gets technical. The same payment can be a clean deductible expense for your company, a tax-free reimbursement for the employee, or a taxable benefit triggering monthly PCB — depending on how you document and classify it.

Here are the five rules that cover most situations in Malaysia:

1. The basic deductibility test

The starting point for any business expense in Malaysia is whether the cost was incurred wholly and exclusively to produce business income.¹

In plain language: if the expense exists only because you're running the business, and serves no personal purpose, it's deductible. If it has a mixed purpose — partly business, partly personal — LHDN and the Malaysian courts have treated it on an all-or-nothing basis in most cases.

When you reimburse an employee for a business cost, you're claiming that deduction. So the receipt, the business purpose, and the policy approval all need to hold up if LHDN ever asks.

2. Travelling allowance: the RM6,000 LHDN exemption

Petrol, travel, and toll allowances paid to an employee for official duties are exempt from individual income tax up to RM6,000 per year.² This is the most commonly used exemption in Malaysian expense policy.

The "official duties" part matters. If an employee uses their personal car to visit clients, attend off-site meetings, or travel between branches, the allowance falls within the exemption. If it's used for the daily commute to and from the office, it doesn't qualify.

Amounts above RM6,000 can still be claimed by the employee, but records need to be kept for seven years to support the claim.²

3. Actual petrol reimbursement vs cash allowance

The tax treatment changes depending on whether you reimburse actual petrol receipts or pay a fixed cash allowance.

A flat monthly petrol allowance — say RM500 paid to every sales rep regardless of how much they actually drive — is a perquisite. It counts toward the employee's taxable income, with the RM6,000 exemption above carved out.

An actual petrol reimbursement — where the employee submits receipts for petrol bought during business trips and you pay back the exact amount — is treated as a reimbursement, not a perquisite. It does not need to be declared as employment income.

The practical takeaway: if you want to keep the tax treatment clean, reimburse actuals against receipts. If you prefer a fixed allowance for simplicity, design it to fit within the RM6,000 exemption and document official duty.

4. When reimbursement is subject to SST

Paying an employee back for a business expense is outside the scope of SST. There's no taxable service between you and your employee, so no SST applies to the reimbursement itself.

SST becomes relevant when your company recovers a cost from a client. If you're a marketing agency that pays for a venue booking and then bills the client for it as part of your service fee, the treatment depends on whether you incurred the cost as principal or as agent.

Costs incurred as principal (a true reimbursement) form part of the value of your taxable service and attract SST. Costs paid purely on the client's behalf, where the supplier's invoice is in the client's name and you recover the exact amount with no markup (a true disbursement), can sit outside SST if strict conditions are met.³

Any markup, handling fee, or admin charge added on top means the recovered amount no longer qualifies as a disbursement, and SST applies.³

5. Entertainment expenses: the 50% deductibility rule

Client entertainment is one of the most common expense categories — and one of the most often misunderstood for tax.

LHDN's rules on entertainment cap the deduction at 50% of the amount spent for most client-facing entertainment.⁴ The other 50% is added back when calculating your chargeable income.

A small number of entertainment expenses are fully deductible, including:

• Staff entertainment such as annual dinners, family days and company outings

• Promotional gifts within Malaysia that carry the company logo

• Promotional samples of the company's products

• Entertainment provided in the ordinary course of a business that exists to provide entertainment (for example, a restaurant or events company)⁴

Entertainment of potential customers — for example, a lunch with a prospect who hasn't yet bought anything — is not deductible at all, because it fails the "wholly and exclusively in the production of gross income" test.⁴

When your finance team approves an entertainment claim, the right tag in your accounting system is what determines whether 50% or 100% is added back at tax time. Misclassifying staff dinners as client entertainment is one of the most expensive small mistakes Malaysian SMEs make.

MyInvois and e-invoice requirements for reimbursements

MyInvois changes what counts as a valid receipt for tax purposes. If your employee buys something on the company's behalf, the document supporting your tax deduction may need to be a validated e-invoice, not the paper receipt from the till.

The RM10,000 rule

From 1 January 2026, any single transaction above RM10,000 must have its own individual LHDN-validated e-invoice.⁵ It cannot be rolled into the supplier's monthly consolidated e-invoice. The rule applies across all industries and is not suspended by the Phase 4 relaxation period.⁵

For reimbursements, this means:

• Single purchase of RM10,000 or less — the paper or PDF receipt is usually fine. The vendor can include it in their monthly consolidated e-invoice without naming your company.

• Single purchase above RM10,000 — the employee must request an individual e-invoice at the point of sale, with your company's TIN as the buyer.

• The threshold is per transaction, not per month or per vendor. Five RM2,500 purchases from the same supplier don't trigger the rule. One RM12,000 purchase does.

Common purchases that hit the RM10,000 threshold

There are some situations in which you typically cross the RM10,000 threshold, such as:

• Business class flights and long-haul international trips

• Hotel stays for multi-day events

• Conference and training fees paid up front

• Laptops, monitors, and other one-off equipment purchases

• Software contracts paid annually

Build a flag into your expense app or claim form so any single line item above RM10,000 prompts the employee to attach an e-invoice, not just a receipt.

Self-billed e-invoices for foreign and individual vendors

Some vendors won't issue a Malaysian e-invoice at all — typically overseas suppliers and certain individual payees. In those cases, your company needs to issue a self-billed e-invoice through MyInvois to record the reimbursement properly.⁵

Here are some common scenarios:

• An overseas SaaS subscription paid by an employee on their personal card

• A freelance contractor in another country paid for a one-off project

• An individual translator, photographer, or trainer paid in cash

How to pay reimbursements faster: DuitNow and IBG

The slowest part of most reimbursement processes isn't approval — it's the gap between approval and the money landing in the employee's account. Many Malaysian SMEs bundle reimbursements into the monthly payroll run. That can mean an employee paying for a client dinner on the 3rd of the month and waiting until the 25th to be paid back.

Malaysia has two payment rails that make same-day reimbursement easy. Most finance teams already use them; they just don't use them for expense claims.

DuitNow: Near-instant transfers

DuitNow is Malaysia's real-time payment rail, run by PayNet and supported by every major bank and most e-wallets. Transfers usually land in the recipient's account within seconds.

For reimbursements, DuitNow has two practical advantages:

• You don't need the employee's bank account number. You can send the payment using their mobile number, NRIC, business registration number, or DuitNow ID.

• The payment is irrevocable and confirmed instantly. Finance gets confirmation, the employee gets the money, and there's no waiting for clearing.

DuitNow is the right rail for one-off reimbursements, urgent payouts, and any claim where speed matters.

IBG: Batched but still same-day

Interbank GIRO is the older rail. Payments are batched and settled at fixed times during the business day. For reimbursements submitted in the morning, money usually lands in the employee's account by the end of the same business day; later submissions clear the next morning.

IBG is the right rail when you're paying out a batch of approved claims at once — say, 30 employees on a Friday afternoon — and don't need real-time confirmation on each one.

Expense reimbursement policy best practices

A written policy is the single best thing you can do to reduce reimbursement disputes, audit risk, and finance team workload. Make sure you have a clear, well-documented policy that employees can reference.

What to include in your expense reimbursement policy

Here are the essentials to include:

• Reimbursable categories — travel, meals, mileage, client entertainment, training, office supplies. Be specific about what's in and what's out.

• Spending limits per category — for example, a daily meal cap, a hotel room rate cap, a per-kilometre mileage rate.

• When pre-approval is needed — typically above a defined amount (often RM500 or RM1,000) or for specific categories like training.

• Submission deadline — usually 30 days from the date of the expense. Anything later requires a justification.

• Documentation required — original receipts, tax invoices, a validated e-invoice for any single purchase above RM10,000, and a trip log for mileage.

• Approval flow — line manager first, then finance. Multi-step approval above a defined threshold.

• Payment method and turnaround — how the company pays and when employees can expect the money.

Documentation standards

The receipt is the foundation of every claim. Without it, the expense isn't deductible for the company and may become taxable for the employee.

• Original digital or paper receipts only.

• Receipts must show the vendor name, date, amount, and SST registration number where it applies.

• For client entertainment, include the client's name, company, and the business purpose.

• For mileage, a trip log with date, start, destination, purpose, and distance.

LHDN expects supporting documents to be kept for seven years. Store everything digitally, tag it against the right expense category, and review the policy at the start of each financial year to keep pace with LHDN and MyInvois updates.

Controls to prevent abuse

The most common forms of expense fraud are small and repeated, not large and obvious. Build in checks for:

• Duplicate receipts — the same receipt submitted twice, often months apart.

• Personal items mixed with business spend — a grocery run tacked onto an "office supplies" claim.

• "Ghost" client entertainment — meals claimed against clients who don't exist or aren't real customers.

Why Malaysian businesses choose Airwallex for expense reimbursement

Manual reimbursement works fine when your team is small and your spend is local. The cracks show up the moment you have more than a handful of employees, multiple entities, or any spend outside Malaysia.

That's where Airwallex comes in. Airwallex Expense Management combines corporate cards, claim submission, approval workflows, and direct MYR payouts in one platform — built for finance teams, not just HR.

Here’s what you get with Airwallex:

Same-day MYR reimbursements via DuitNow and IBG

When a claim is approved in Airwallex, finance can pay the employee back the same day through DuitNow or IBG, directly from their Airwallex Malaysia account. No exporting a file from the accounting system. No logging into a separate bank portal. No batch upload.

For most teams, this cuts the average reimbursement turnaround from two to three weeks down to one or two business days.

Corporate cards that reduce reimbursement entirely

The most efficient reimbursement is the one that never happens. With Airwallex corporate cards, you can issue physical and virtual cards in MYR, USD, SGD, and other currencies to employees, with per-card spending limits and merchant category controls.

The reimbursement process still exists for the cases where it's needed, but a corporate card removes most of the routine claims that clog up the queue.

AI policy enforcement, in real time

Airwallex's Expense Policy Agent reviews every claim against your written policy as it's submitted. If a claim breaks a rule, it's flagged with the specific rule that was broken, before it ever reaches a manager's inbox.

Managers approve faster because the obvious problems are caught upstream, finance spends less time on policy questions, and employees get a clear answer on what's wrong with a claim instead of a vague rejection.

Approval workflows built for finance, not HR

Most expense tools were built as an extension of HR or payroll software. Airwallex was built for finance teams, with:

• Multi-step approval flows by amount, category, or entity

• Automatic policy tagging for SST treatment and entertainment vs staff meals

• Direct integration with Xero, QuickBooks, NetSuite, and other accounting systems

• A receipt and approval trail that satisfies LHDN's seven-year retention requirement

Multi-currency support for international claims

For Malaysian businesses with overseas teams, suppliers, or business travel, claims often come in across multiple currencies. With Airwallex, you can hold and reimburse in MYR, USD, SGD, GBP, EUR, and dozens of other currencies — using interbank FX rates that save you up to 80% on FX fees.

Frequently asked questions (FAQs)

Is expense reimbursement taxable in Malaysia?

An expense reimbursement is generally not taxable for the employee, as long as the amount matches the actual cost, the receipt is kept, and the spend was for business purposes. For the company, the cost is deductible if it meets the standard tax test. The treatment changes if you pay a fixed cash allowance instead of reimbursing actuals — that can be taxable as a perquisite.

What's the difference between an expense reimbursement and an allowance?

A reimbursement pays back the exact amount an employee already spent, supported by a receipt. An allowance is a fixed payment given to an employee, often monthly, regardless of actual spend. The tax treatment is different: reimbursements are usually outside the employee's taxable income, while most allowances are treated as a perquisite, with some exemptions (such as the RM6,000 travelling allowance).

Can I claim expense reimbursement without a receipt?

In most cases, no. Without a receipt, the company can't prove the expense was for business purposes, so it can't claim the tax deduction — and the payment to the employee may be reclassified as a taxable benefit. Some companies allow a small exception for genuinely lost receipts, with a signed declaration from the employee, but this should be rare.

How long should it take to be reimbursed?

There's no legal requirement in Malaysia, but most well-run businesses pay approved claims within 5 to 10 business days. Companies that bundle reimbursements into monthly payroll can take up to 30 days. With Airwallex Expense Management, approved claims can be paid same-day in MYR through DuitNow or IBG.

Do expense reimbursements need to go through payroll?

No. Many Malaysian businesses pay reimbursements separately from payroll, which is faster for the employee and cleaner for accounting — reimbursements aren't taxable income, so mixing them with salary lines creates confusion on payslips and EA forms. Paying through payroll is administratively simpler, but it's a trade-off against speed.

Are entertainment expenses fully reimbursable to employees?

Yes. You reimburse the employee for the full amount they spent — the 50% deductibility rule is a company tax matter, not a reimbursement matter. The employee gets paid back in full; finance applies the 50% add-back when filing the company's tax return.
