When you get married in Malaysia, your taxes do not automatically change. You and your spouse still file your own returns every year. But unlike single filers, married couples get to choose how they do it. You can file separately, the same way you always have, or you can combine both your incomes into one joint tax return.
Most couples do not realise this is a choice at all. And for many, picking the wrong option means paying more tax than they need to.
The first option is separate assessment, where you and your spouse each file your own individual return. Each of you claims your own set of tax reliefs, and each of you pays whatever tax you personally owe. Nothing really changes from when you were single, except that being married opens up a few extra reliefs you can claim.
The second option is joint assessment, where you combine both your incomes into one tax return under one spouse’s name. The couple pays tax based on the combined total, the spouse whose name the return is filed under claims all the reliefs, and only one tax bill comes out at the end.
You can, yes. Malaysia’s tax system works on a sliding scale, the more you earn, the higher the percentage of tax you pay on the upper portion of your income. So combining two incomes into one return can sometimes push that combined total into a higher tax bracket than either of you would have reached on your own.
Whether filing together saves you money or costs you money depends mostly on how different your incomes are.
If both of you earn similar amounts, filing separately might work out better. You each get a full set of tax reliefs, and neither of you crosses into a higher bracket because of the other.
If one spouse earns a lot more than the other, filing together is worth checking. Sometimes combining the incomes does not push the higher earner into a worse bracket, and you gain access to an extra RM4,000 relief that you would not get filing separately (see below).
If one spouse has no income at all, filing together is usually the better option.
The good news is that you do not have to guess. You can run through both options inside the MyTax portal before you submit anything, and it will show you the tax payable either way.
| Filing Separately | Filing Together | |
| Each spouse’s reliefs | Each of you gets a full, independent set | Some relief caps are shared between both of you |
| Lifestyle relief | Up to RM2,500 each (RM5,000 total) | Up to RM2,500 for both of you combined |
| Spouse relief (RM4,000) | Only claimable if your spouse has zero income | Claimable even if your spouse has income |
| Tax brackets | Each person is taxed on their own income only | Both incomes are added together before tax is calculated |
| RM400 tax rebate | Each spouse can qualify individually | Can qualify for up to RM800 if spouse relief is also claimed |
| Best for | Couples where both spouses earn similar amounts | Couples where one spouse earns significantly more, or very little |
If your spouse has no income at all, you can already claim a RM4,000 relief on your own return, regardless of whether you file together or separately. This is the spouse relief, and it reduces the amount of your income that gets taxed.
But if your spouse does earn income, you can only claim that RM4,000 if your spouse agrees to have their income included in your return (in other words, if you file together under your name). File separately, and the RM4,000 goes away.
For some couples where one spouse earns very little, this trade-off is worth it. The RM4,000 reduction in the higher earner’s taxable income can outweigh any downsides from combining the incomes.
When you file separately, both you and your spouse each get your own full set of reliefs. That means two separate RM9,000 personal reliefs, two separate lifestyle relief claims of up to RM2,500 each, two separate EPF and insurance relief claims, and so on.
When you file together, the reliefs do not simply double up. Some categories get a shared cap rather than two individual ones. The lifestyle relief, for example, is capped at RM2,500 for the household rather than RM2,500 per person.
So if both of you spend on books, gym memberships, or gadgets and each claimed RM2,500 separately, you would get RM5,000 in combined relief filing separately. Filing together, that becomes RM2,500 between the two of you.
This is one of the main reasons filing separately usually wins when both spouses have decent incomes.
If your chargeable income (that is, your income after all reliefs have been subtracted) comes to RM35,000 or less, you get a RM400 tax rebate. This is money taken directly off your tax bill, not just off your income.
If you file together and also claim the spouse relief, you get an extra RM400 rebate on top of that, for a possible RM800 total.
This rebate only applies if the chargeable income is RM35,000 or below, so it is mainly relevant for couples where one or both spouses are on a lower income. If the combined income pushes you well past that threshold, it does not factor in.
If either spouse runs a business, does freelance work, or has any self-employment income, the decision becomes a bit more involved. Business losses from one spouse cannot be used to reduce the other spouse’s income even when filing together. Each person’s business figures are calculated separately first, and only the final totals get combined.
If this applies to you, it is worth speaking to a tax consultant or licensed tax agent before deciding which option to use.
You make the choice inside your income tax return on MyTax. When filling in your form, you will see a section that asks how you want to be assessed. If you want to file together, the spouse whose income is being added in will need to elect to do so in their own return.
You can change this every year. There is no permanent commitment to either option, so if filing together works better one year and separately works better the next, you can switch.
The deadline is 30 April for those with employment income only, and 30 June for those with business income.
