You Made RM800 a Month on the Side. LHDN Counts It the Same Way.

You Made RM800 a Month on the Side. LHDN Counts It the Same Way.

The extra income felt informal. The tax obligation is not.

The question arrived in a WhatsApp group at 11pm. Someone had been selling cakes from home for about a year, maybe RM600 to RM900 a month, and wanted to know if she needed to declare it to LHDN. Three people replied immediately. The answers contradicted each other.

This is what happens when side income is no longer unusual. It is normal. Nearly everyone knows someone who sells something, drives something, teaches something after hours. The earning part has become routine. The declaring part never caught up.

Technically, LHDN's position is fairly straightforward. All income is taxable. That includes kuih sales, Grab earnings, freelance work, commissions, tuition fees, dividends from an online shop. The law does not distinguish between primary income and secondary income. Money comes in, it counts.

Practically, most people do not know this, or know it vaguely and have never acted on the knowledge.

The threshold most people reference is RM34,000 a year in total income. Below that, after personal reliefs, you likely owe nothing. Above it, you should be filing. Your salary is already deducted through PCB, the monthly scheduled tax deduction, but that deduction only accounts for what your employer pays you. The income you earn outside that job is invisible to the system unless you tell it.

This is where it gets uncomfortable. If you earn business income, even RM500 a month selling nasi lemak, you are technically supposed to file Form B, not Form BE. Form B is for individuals with business income. Most salaried people file Form BE automatically and have never touched Form B in their lives. The switch feels like entering a category that does not belong to them.

And then there is the question of records. Business expenses can be deducted from business income, ingredients, petrol, phone maintenance, whatever it took to produce the money. But you need to keep records. Receipts. Tallies. Proof. Most people running side income keep none of this because it never felt like a business. It felt like helping out.

The risk used to be theoretical. LHDN had limited resources. Audits focused on larger earners. The probability of someone making RM800 a month selling cakes being individually flagged was low.

That is changing. E-invoicing means more transactions are visible. Platforms report earnings. Bank transfers leave trails. The gap between what you declare and what the system can see is narrowing, not because the law changed, but because the enforcement capability did.

Nobody is saying that the kuih seller that night needs to worry about an audit. But the question she asked, whether she needs to declare, has an answer. The answer is yes. It has always been yes. It is just that nobody ever felt the need to tell her.

The hardest part is not the tax. The tax might be small or zero. The hard part is realising that the weekend money that felt so informal actually has a category, and that category was always there, waiting quietly while nobody looked.
