Key takeaways
- A tax deduction in Malaysia is a business expense you subtract from gross income. You then pay tax on a smaller amount.
- Deductions, reliefs and rebates each lower your tax at a different stage. Knowing which one you’re claiming helps you get the full benefit.
- Business assets are claimed through capital allowances over time. Some costs, like client entertainment, are only partly deductible.
- Organised receipts and invoices make every claim easy to back up. Recording expenses as you go saves a rush at filing time.
What is a tax deduction?
A tax deduction is a business expense you subtract from your gross income, so you pay tax on less. Your gross income is everything your business earns before any deductions.
In Malaysia, the Income Tax Act 1967 sets the rules, and the Inland Revenue Board of Malaysia (LHDN) applies them. Under section 33(1), an expense is deductible when it’s wholly and exclusively incurred in producing your gross income, subject to the restrictions in section 39.
Picture a café owner. The coffee beans, shop rent, electricity bill and barista’s wages all go into earning café income, so each one passes the test.
Deductions are one of several ways to lower your tax bill. The next section shows how they differ from reliefs and rebates.
Tax deductions vs tax reliefs vs tax rebates
All three reduce the tax you pay, but each one applies at a different point in the calculation. Knowing where each one applies shows you what it’s worth.
A tax deduction comes off your gross income first. It covers the costs of running your business, whether you trade as an individual or through a company.
A tax relief is a personal allowance for individuals, subtracted later to reach your chargeable income. For year of assessment (YA) 2026, resident individuals receive RM9,000 in self relief.
A tax rebate comes off the tax itself, once it’s worked out. If your chargeable income is RM35,000 or less, you get a RM400 rebate, and any amount above your tax bill isn’t refunded.
A rebate saves its full face value, while a deduction saves a share of itself set by your tax rate. The example below shows that in action.
Example of a tax deduction calculation
Aisyah runs a graphic design business as a sole proprietor. In YA 2026, her business earns RM120,000 in gross income and she spends RM30,000 on deductible business expenses.
RM120,000 gross income minus RM30,000 deductible expenses leaves RM90,000. The Income Tax Act 1967 calls this figure adjusted income, and it’s the starting point for her tax.
Resident individuals pay progressive rates from 0% up to 30%, so higher slices of income are taxed at higher rates. Because the RM30,000 comes off the top of her income, it saves tax at her top rates.
Aisyah’s personal reliefs and any rebate apply after this step. Her final bill depends on her full situation and is worked out when she files.
Types of tax deductions for small business
Most small business claims fall into a handful of groups. Each group has its own treatment, so sorting expenses correctly makes filing faster.
Day-to-day operating expenses
These are the regular costs of keeping your business running. They include shop or office rent, utilities, staff salaries, marketing and professional fees for your accountant or lawyer.
Because you pay them often, they’re easy to miss. When you capture and categorise expenses as you pay them, each one is ready to claim at year end.
Capital allowances instead of depreciation
In Malaysia, you claim capital allowances on business assets like equipment or vehicles in place of accounting depreciation. The allowances are based on what the asset cost you.
You get an initial allowance in the year you buy and start using the asset, then an annual allowance each year it’s in use. Information and communication technology (ICT) equipment and software get 40% initial and 20% annual allowances, while motor vehicles have limits on qualifying cost.
Checking those limits before you buy a vehicle avoids surprises at filing time. When you track your fixed assets in one register, cost and purchase dates are easy to find.
Entertainment expenses
Entertainment gets special treatment under the Income Tax Act 1967. Under section 39(1)(l), entertainment is generally 50% deductible, which covers most client meals and hospitality.
Entertainment for your employees is treated more generously. Free staff meals, annual dinners, outings and family days can qualify for a full 100% deduction under Public Ruling 4/2015.
Mixed-use and home-based costs
Some costs cover both business and private use, like a mobile phone or a room at home you work from. Section 39 blocks private and domestic expenses, so you claim only the business portion.
If you use your phone 70% for business, for example, you’d claim 70% of the bill. Keep a note of how you worked out the split, as that’s what supports the claim.
Business losses you can carry forward
A loss-making year still has value at tax time. You can carry unutilised business losses forward for up to 10 consecutive YAs, and unabsorbed capital allowances can be carried forward indefinitely.
That means start-up costs in a slow first year can lower tax in your stronger years. Knowing what’s claimable also means knowing where the limits are.
What you can’t claim as a tax deduction
Section 39 of the Income Tax Act 1967 lists the expenses LHDN won’t allow. For small businesses, these are the ones that come up most:
- private or domestic spending, like groceries, family holidays and personal clothing
- capital expenditure on assets, which you claim through capital allowances instead
- the non-deductible half of client entertainment
- the private portion of any mixed-use cost
If a cost sits in a grey area, an accountant or bookkeeper can check it before you file. Once your list is clean, claiming is straightforward.
How to claim tax deductions
You claim deductions through your annual tax return. Follow these five steps each year:
- Keep a receipt or invoice for every business expense when you pay it
- Check that each expense was spent to earn your business income
- Remove private portions and the restricted half of client entertainment
- Move asset purchases out of expenses and claim capital allowances on them
- File your return by the deadline: Form B by 30 June for sole proprietors, or Form C within seven months of accounts closing for companies
If you run a partnership, the partnership files Form P. Each step depends on good records, which the next section covers.
Record keeping requirements
Your records are the evidence behind every deduction you claim. Good records make filing quicker and give you a clear answer if LHDN asks questions.
What records to keep
Keep invoices, receipts, bank statements and contracts for all business transactions. Storing them in accounting software keeps each document linked to the transaction it supports.
For each expense, your records should show:
- what you bought
- when and where you bought it
- how much you paid
- how it relates to your business
How long to keep records
Plan your storage around the period LHDN sets. LHDN asks you to keep records and documents for seven years for audit purposes.
E-invoicing and your records
E-invoices are becoming a standard part of business records in Malaysia. Businesses with annual turnover below RM3 million are exempt from issuing e-invoices, although exceptions apply to businesses linked to larger related companies.
The threshold rose from RM1 million to RM3 million from 1 September 2026, and Bernama reported that the change exempts more than 1.1 million businesses. If you’re above the threshold, e-invoicing software keeps those invoices stored alongside your other records.
Common tax deduction mistakes to avoid
Most deduction errors come from a few familiar habits. Spotting them early helps you claim with confidence.
Mixing personal and business costs
Paying private bills from your business account blurs the line between the two. A separate business account makes the business portion of each cost clear.
Treating asset purchases as running expenses
A new laptop or delivery van is a capital purchase, so it belongs in your asset register. Claim it through capital allowances rather than as a one-off expense.
Deducting client entertainment in full
Client lunches and hospitality are usually only half deductible. Tag them separately from staff events, which can qualify in full, so the split is easy at filing time.
Losing the paperwork behind a claim
Faded or lost receipts leave a claim with no evidence behind it. When you snap photos of receipts as you get them, each one stays readable for the full retention period.
Good habits are easier to keep with tools that do the sorting for you.

FAQs on tax deductions
Here are quick answers to common questions about tax deductions in Malaysia.
Do I need to submit receipts with my tax return?
You keep your receipts rather than sending them in with your return. LHDN can ask to see them later, which is why its FAQ on individual tax tells you to keep them for seven years.
Is PCB (MTD) the same as a tax deduction?
Monthly tax deduction (MTD), known in Malay as potongan cukai bulanan (PCB), is income tax employers withhold from employees’ pay each month. It’s a prepayment towards each employee’s final tax bill, so it works differently from a business deduction.
Can a sole proprietor claim both business deductions and personal reliefs?
Yes. Business deductions reduce your business income first, then personal reliefs, such as the RM9,000 self relief for YA 2026, reduce your chargeable income.
Do SMEs pay a lower tax rate?
For YA 2026, qualifying resident small and medium enterprises (SMEs) pay 15% on the first RM150,000, 17% on the next RM450,000 and 24% above RM600,000. To qualify, a company needs paid-up capital of RM2.5 million or less and gross business income of RM50 million or less, among other conditions.
Can I claim the full cost of a small asset in one year?
Yes, if the item costs less than RM2,000: small-value assets qualify for a 100% capital allowance, subject to a total cap of RM20,000.
How do I know if an expense is deductible?
Ask yourself whether you’d have spent the money if you didn’t run the business. If you would, it’s likely a private cost, and a tax agent can confirm any borderline items.
