Why medical relief matters on your tax return
Lembaga Hasil Dalam Negeri (LHDN / IRBM) lets you subtract certain medical expenses from your chargeable income before tax is calculated. Because Malaysia uses a progressive tax system, every ringgit of relief you claim reduces the income taxed at your top rate — so a few thousand ringgit of legitimate medical claims can translate into real savings.
Medical relief is not one single deduction. It is a cluster of separate reliefs and sub-limits covering serious illness, fertility treatment, vaccination, full medical check-ups, mental health support, and the care of your parents. Each has its own cap and its own rules, and you claim them in the relief section of your e-Filing form (BE for employment income, B for business income).
Most of these reliefs are claimed for the relevant year of assessment — meaning the calendar year in which you paid the bill. Keep this guide handy when you reconcile your EA form and receipts before filing.
Serious medical treatment for yourself, spouse or child
The largest medical relief covers expenses for serious diseases such as cancer, kidney failure requiring dialysis, heart conditions, Parkinson's, leukaemia and similar conditions. This relief applies to treatment paid for yourself, your spouse, or your child, and it is usually combined into a single shared cap with several other medical sub-categories.
Within that combined cap, LHDN groups together a number of expense types. The category as a whole carries one overall ceiling (commonly several thousand ringgit), and certain items inside it — such as full medical check-ups — have their own smaller sub-limit that sits within the larger figure.
- Treatment of serious diseases for self, spouse, or child
- Fertility treatment, including IVF and IUI, for yourself or your spouse
- Vaccination expenses for a defined list of covered vaccines
- A full medical check-up (subject to a sub-limit within the overall cap)
- Mental health examinations or consultations and certain learning-disability assessments for children, where covered
The full medical check-up sub-limit
A complete medical check-up is one of the most commonly claimed items, partly because it is something healthy taxpayers can do every year. The catch is that it does not get its own separate allowance — it sits inside the broader medical relief and has a smaller sub-limit (often around RM1,000) that counts toward the overall medical cap.
In recent years LHDN has widened this sub-category to include mental health support such as consultations with registered psychiatrists, clinical psychologists, or licensed counsellors, as well as certain assessments and early-intervention programmes for children with learning disabilities. Because the exact scope and figure are reviewed in most national budgets, confirm the current year's wording and amount on the official LHDN website before you claim.
Fertility treatment and vaccination
Fertility treatment — including in-vitro fertilisation (IVF), intrauterine insemination (IUI), and related procedures — can be claimed for yourself or your spouse, and typically falls under the same combined serious-medical cap. Because fertility cycles are expensive, this is one area where careful receipt-keeping pays off.
Vaccination relief covers a defined list of vaccines (for example influenza, pneumococcal, HPV, COVID-19 and certain others) for yourself, your spouse and your children. It is usually capped at a modest amount within the medical relief group. As with every figure here, treat these caps as typical for the current year of assessment and verify the latest list and limit with LHDN.
Parental care and parents' medical expenses
Looking after ageing parents carries its own relief, separate from your personal medical claims. Historically this has taken two forms that you cannot double-claim: a relief for your parents' medical, dental, special-needs and carer expenses (supported by a medical practitioner's certification), and a smaller flat relief for parental care when no medical bills are claimed.
The expenses must generally be for parents who are resident in Malaysia, and where medical treatment is involved you will usually need certification from a registered medical practitioner confirming the parent's condition or need for care. Siblings sometimes share these costs — but only the person who actually paid and holds the receipts should claim, and the total claimed across the family cannot exceed the cap.
- Medical treatment, dental treatment (non-cosmetic) and special-needs care for parents
- Carer fees or expenses for parents needing assistance with daily living
- Complete medical examination for parents, where covered
- A separate flat parental-care relief if you are not claiming parents' medical expenses
Documentation: what LHDN wants you to keep
You do not attach receipts when you file on e-Filing, but LHDN can ask for them in an audit for up to seven years. Claiming a relief you cannot support with documents is the fastest way to turn a small saving into a penalty, so treat record-keeping as part of the claim.
For ordinary items (vaccination, a check-up) a dated official receipt in the patient's name is usually enough. For serious-illness and parental-care claims, you will also want a medical certification or letter from a registered practitioner confirming the diagnosis or the need for care. Keep digital scans so a faded thermal receipt does not cost you the deduction.
- Original tax invoices or official receipts showing the date, amount, and patient name
- A letter or certification from a registered medical practitioner for serious illness and parental-care claims
- Proof of relationship where relevant (for spouse, child, or parent claims)
- Records retained for at least seven years in case of an LHDN review
Caps change yearly — track reliefs as you go
The single most important rule with medical relief is that the amounts move. National budgets regularly adjust the overall medical cap, the check-up sub-limit, the vaccination allowance and the parental-care figures. A number that was correct two years ago may be too low — or no longer valid — today, so always reconcile against the current year of assessment on the official LHDN website before you file.
Because these reliefs span several family members, multiple receipts and overlapping sub-limits, they are easy to under-claim or accidentally double-count. CukaiBro lets you log each medical receipt against the right relief category, warns you when you hit a sub-limit, and recomputes your tax payable in real time so you can see the effect of every claim before you submit on MyTax.
