Side Income Tax Malaysia — When to Declare, How to Register, What You Can Claim

You have a full-time job and a side hustle. Maybe you freelance on weekends — design work, copywriting, consulting. Maybe you sell products on Shopee. Maybe you tutor students after hours, drive Grab on weekends, or earn commission from affiliate marketing.

The income is real. The question is: what does LHDN want from you?

The short answer is that all income earned in Malaysia is taxable, and if your total income crosses the filing threshold, you must declare it — including the side income your employer knows nothing about. The longer answer involves SSM registration, expense deductions, the interaction between PCB and your side income, and the point where a proper business structure makes financial sense.

This guide walks through all of it, from the first ringgit of side income to the point where you are running a real business on the side.

When Does Side Income Become Taxable?#

Immediately. There is no "side income exemption" or "hobby income threshold" in Malaysian tax law. If you earn income — whether from employment, business, rental, royalties, or any other source — it is subject to Malaysian income tax under the Income Tax Act 1967.

The practical question is not "is it taxable?" (it is) but "do I need to file a return?"

Filing threshold#

LHDN's individual FAQ (hasil.gov.my, last updated 26 June 2026) says a single individual with employment income of more than RM34,001 a year (after EPF deduction) must register a Tax Identification Number, and a business owner must register even if the business makes a loss. That is a registration threshold. Under section 77 of the Income Tax Act 1967 you must submit a return if you have taxable income for the year of assessment, or, without taxable income that year, if you had taxable income, filed or were required to file for an earlier year.

If you are already filing a tax return for your employment income, adding side income means you declare it in the same return — using Form B (for individuals with business income) instead of Form BE (for individuals with employment income only).

What counts as "side income"#

Any of these count:

• Freelance fees (design, writing, coding, consulting, tutoring)
• Online sales (Shopee, Lazada, Carousell, Instagram)
• Gig economy earnings (Grab, foodpanda, Lalamove)
• Affiliate commissions
• Content creation revenue (YouTube, TikTok, sponsorships)
• Rental income from property
• Royalties (books, music, software)
• Commission or referral fees

The tax treatment differs slightly depending on whether the income is classified as business income (Section 4(a) of the ITA) or other income — but the principle is the same: declare it all.

SSM Registration — Do You Need It?#

If your side activity constitutes carrying on a business in Malaysia, you are required to register with SSM (Suruhanjaya Syarikat Malaysia / Companies Commission) under the Registration of Businesses Act 1956.

What counts as "carrying on a business"#

There is no bright-line revenue threshold. The test is whether the activity is regular, systematic, and conducted for profit. Indicators include:

• You have recurring clients or customers
• You invoice for your services
• You have a business name, logo, or website
• You hold yourself out as offering services to the public
• The activity generates income on a regular (monthly, weekly) basis

A single freelance project for a friend probably does not require registration. Regular monthly freelancing for multiple clients almost certainly does.

How to register#

Sole proprietorship (Enterprise / Perniagaan Tunggal) — the simplest structure:

1. Go to SSM's Ezbiz portal (ezbiz.ssm.com.my)
2. Search for your desired business name (must be unique)
3. Register — cost is RM60/year for a one-owner enterprise with a business name
4. Registration is typically processed within 1–3 working days
5. You receive your SSM registration certificate (Perakuan Pendaftaran)

You need this registration number to:

• Open a business bank account
• Issue proper invoices
• File Form B with business income
• Apply for certain business-related tax deductions

Do I register as a sole prop or Sdn Bhd?#

Almost always start as a sole proprietor. The sole prop is RM60/year with minimal compliance. SSM charges RM50 to reserve a company name and RM1,000 to incorporate a company limited by shares (plus RM10 for sharing the company's data with other agencies), and professional fees for setting up vary, so get quotes. An Sdn Bhd also adds company secretary fees that vary by firm (get quotes) and must appoint an auditor each financial year unless it qualifies for SSM's audit exemption, which turns on revenue, total assets and employee numbers (Practice Directive 10/2024; see the Sole Proprietor vs Sdn Bhd Guide for the thresholds).

The Sdn Bhd conversation starts when your side income consistently exceeds RM200,000/year gross and your personal tax rate meaningfully exceeds the SME corporate rates (15% on the first RM150,000 of chargeable income and 17% on RM150,001 to RM600,000). For the full comparison, see our Sole Proprietor vs Sdn Bhd Guide.

How is side income taxed?#

Filing form#

If you have business/freelance income, you file Form B (not Form BE). Form B is for individuals with business income. The deadline is 30 June of the following year (e.g., Form B for year of assessment 2025 is due by 30 June 2026). If you e-File, LHDN gives Form e-B a 15-day grace period, to 15 July 2026 for YA2025; a Form e-B furnished after that is treated as late from 1 July.

Form BE (employment income only) has an earlier deadline, 30 April. These dates are from LHDN's filing programme for 2026 as read on 11 October 2026; hasil.gov.my blocked our requests on 17 and 25 October 2026, so they were not re-checked: confirm them with LHDN. Moving to Form B gives you more time, but it also requires more detailed reporting.

How the tax is calculated#

Your total chargeable income is the sum of all income sources minus allowable deductions and reliefs:

Tax is then calculated on RM96,500 using the Malaysian individual tax rate brackets:

Tax brackets are subject to annual Budget announcements. Verify the current rates for your assessment year on the LHDN website or see our Malaysia Income Tax Guide 2026.

The PCB interaction#

Your employer deducts PCB (Potongan Cukai Bulanan) from your salary based on your employment income alone. PCB does not know about your side income.

When you file Form B:

1. Your total tax is calculated on all income (employment + business + others)
2. PCB already deducted by your employer is credited against the total tax
3. The difference — additional tax on the side income — is what you owe

If your side income is substantial and growing, LHDN may issue a CP500 notice directing you to pay tax on your non-employment income by instalments, at the times and in the amounts it sets (Income Tax Act s107B; the Act does not fix the months). CP500 is essentially PCB for non-employment income — it spreads the tax burden across the year rather than hitting you with one large bill at filing time.

If you receive a CP500 notice, you must pay the instalments. An instalment still unpaid 30 days after its due date is increased by 10% of the unpaid amount (s107B(3)).

For a detailed walkthrough of the filing process, see our e-Filing MyTax Guide and Income Tax Filing Guide.

Which expenses can you deduct from side income?#

This is where side income tax gets interesting — and where most freelancers leave money on the table.

Under Malaysian tax law, you can deduct expenses that are wholly and exclusively incurred in the production of your business income. The key phrase is "wholly and exclusively" — the expense must be directly related to earning the freelance/business income.

Common deductible expenses for freelancers#

Capital allowance vs revenue expense#

Equipment and assets that last more than one year (computer, camera, furniture) are treated as capital expenditure. You cannot deduct the full cost in the year of purchase. Instead, you claim capital allowance — a depreciation deduction spread over the asset's useful life.

Standard capital allowance rates:

• Computers and IT equipment: 20% initial allowance + 40% annual allowance
• Office furniture and fittings: 20% initial + 10% annual
• Motor vehicles (business use): 20% initial + 20% annual

Software subscriptions, internet bills, and other recurring costs are revenue expenses — fully deductible in the year incurred. This is one reason subscription-based tools (Adobe CC at RM250/month) are more tax-friendly than one-off software purchases (RM3,000 perpetual licence).

Record-keeping requirements#

The Income Tax Act requires anyone carrying on a business to keep sufficient records for seven years from the end of the year to which the business income relates (s82(1)). This includes:

• Invoices issued and received
• Bank statements showing income and expense transactions
• Receipts for all claimed expenses
• Mileage log (if claiming travel)
• Home office measurement documentation (if claiming home office)

You do not need to submit these with your tax return. But if LHDN audits you, they will ask for them — and if you cannot produce records, the deductions are disallowed.

Can you pay into EPF and SOCSO on side income?#

Your employer handles EPF and SOCSO contributions for your employment income. But your side income has no employer — no one is making contributions on your behalf.

EPF (i-Saraan / Caruman Sukarela Insentif Persaraan)#

Self-employed Malaysians (including those with a side business) can make voluntary EPF contributions through the i-Saraan programme. The government provides a special incentive of 20% of your voluntary contributions in the current year, capped at RM500 a year, with a lifetime cap of RM5,000 or until you turn 60, whichever comes first. Contributing about RM2,500 in a year earns the full RM500. KWSP does not publish a monthly-income ceiling for i-Saraan.

You can contribute up to RM100,000 per year in voluntary contributions — one ceiling shared across i-Simpan, i-Saraan, i-Saraan Plus, i-Suri and Akaun Persaraan Top-Up. The EPF tax relief (up to RM4,000 for the mandatory portion or combined with voluntary contributions) may apply, depending on your total EPF deduction from employment.

This is worth doing even if the amounts are small — the government match and the EPF dividend (historically 5–6% for conventional) make it a strong risk-free return. See our EPF Complete Guide 2026 for the full mechanics.

SOCSO (Self-Employment Social Security Scheme)#

If you are a gig economy worker (Grab, foodpanda, Lalamove, etc.), you are covered under SOCSO's Self-Employment Social Security Scheme — registration is mandatory for designated gig platforms. The contribution is shared between you and the platform operator.

For other freelancers and side-business operators, SOCSO registration is voluntary but increasingly advisable. It provides employment injury coverage and invalidity protection.

EIS (Employment Insurance System)#

EIS covers job loss — it does not apply to self-employment income. Your EIS contributions from your employment are unaffected by your side income.

e-Invoice Compliance — Does It Apply to You?#

Malaysia's e-Invoice system (MyInvois) is being rolled out in phases, starting with larger businesses and progressively extending to smaller ones.

As of 2026, the e-Invoice mandate applies based on annual turnover thresholds. If your side business turnover exceeds the applicable threshold for your implementation phase, you must issue e-Invoices through LHDN's MyInvois system.

For most side-income earners and small freelancers, the threshold has not yet been reached — but it is worth checking the current phase and threshold. See our e-Invoice Malaysia Guide 2026 for the current implementation timeline and whether you are affected.

What changes when side income becomes your main income?#

There is a tipping point where the side hustle is no longer "side" — it is a business that happens to coexist with a job.

Signs you have crossed the line#

• Side income exceeds 30–50% of your employment income
• You are spending 15+ hours per week on the side activity
• You have recurring clients who depend on your availability
• You are turning down work because of time constraints
• Your CP500 instalments are substantial

At this point, several decisions become urgent:

1. Formal business structure. If you have not registered with SSM yet, do it now. If revenue is consistently above RM200,000/year, run the Sole Prop vs Sdn Bhd analysis — see the full comparison guide.

2. Separate bank account. Open a business bank account and route all business income and expenses through it. This simplifies accounting, makes tax filing cleaner, and creates a clear audit trail.

3. Proper bookkeeping. Move beyond spreadsheets to proper accounting software. Options include SQL Account, AutoCount, Wave (free), or QuickBooks. The cost is deductible.

4. Tax agent. Once your tax situation involves business income, capital allowances, and expense deductions, a tax agent (RM500–1,500/year for a sole prop) earns their fee by optimising your deductions and ensuring compliance. The fee itself is tax-deductible.

5. Insurance. Professional indemnity insurance (if you provide services), public liability (if clients visit your premises), and keyman insurance (if the business depends on you). Review whether your existing life insurance coverage is adequate given your dual income streams.

Common Mistakes to Avoid#

Not declaring side income because "it's small." LHDN does not set a minimum threshold for taxability. If you are required to file a return and you omit income, that is underreporting — which carries penalties of 35–100% of the tax undercharged, plus potential prosecution for serious cases. Not worth the risk.

Using Form BE instead of Form B. If you have business income, you must file Form B. Filing Form BE (employment income only) when you have business income is incorrect and can trigger a reassessment if LHDN identifies the discrepancy.

Not keeping receipts. The most common reason freelancers pay more tax than necessary — they incur legitimate business expenses but cannot prove them during an audit because the receipts are gone. Digital receipt storage (photos of receipts, email confirmations, bank statements) counts. Keep them for seven years from the end of the year to which the business income relates (s82(1)).

Claiming personal expenses as business expenses. Your Netflix subscription is not a business expense (unless you are specifically a streaming content reviewer, and even then it is arguable). Your family holiday is not a business trip. LHDN auditors are experienced at spotting inflated expense claims. Claim what is genuinely and wholly incurred for business — nothing more.

Ignoring CP500 notices. If LHDN issues a CP500 notice, you must pay the instalments. An instalment still unpaid 30 days after its due date is increased by 10% of the unpaid amount (s107B(3)). If your actual income is lower than the CP500 estimate, you can apply to LHDN to vary the instalments, once by 30 June and once by 31 October of the year (s107B(2)), but you cannot simply not pay.

Not separating business and personal finances. Running side income through your personal bank account makes expense tracking harder, creates audit risk, and makes it difficult to demonstrate which expenses are genuinely business-related. A separate account — even if it is just a second personal savings account dedicated to the business — solves this.

Frequently Asked Questions#

Do I need to declare side income to LHDN if I already have a full-time job?

Yes. All income earned in Malaysia is taxable and must be declared. If you must file a return under section 77 (see the Filing threshold section above), it must include all sources — employment, business, rental, and any other income.

Do I need to register a business with SSM for freelance work?

If you are carrying on a business — regular, systematic activity for profit — yes. Registration costs RM60/year for a sole proprietorship. A one-off freelance project may not require registration, but regular freelancing with recurring clients almost certainly does.

What expenses can I deduct from my side income?

Expenses wholly and exclusively incurred in producing the business income: equipment (via capital allowance), software subscriptions, internet and phone (business portion), home office costs (proportional), travel for client meetings, marketing, professional development, and professional fees. Keep receipts for 7 years.

How does PCB work if I have both employment and side income?

PCB covers your employment income only. When you file Form B, total tax is calculated on all income combined. PCB already paid is credited against it. The balance is what you owe. LHDN may also issue a CP500 notice directing you to pay tax on non-employment income by instalments.

At what point should I register as a sole proprietor vs incorporate as Sdn Bhd?

Start as a sole proprietor — RM60/year, minimal compliance. Consider Sdn Bhd when side income consistently exceeds RM200,000/year gross, your personal tax rate materially exceeds 17%, you need limited liability, or clients require a company registration. See the Sole Proprietor vs Sdn Bhd Guide for the full comparison.

What to Do Next#

If you are earning side income right now, here is your action list — in order:

1. Check your filing obligation. If you have taxable income once salary and side income are added together (or had taxable income or filed in an earlier year), you must file. If you are already filing Form BE, switch to Form B.
2. Register with SSM if your side activity is regular and for profit. Do this within 30 days of starting (or now, if you have been operating without registration).
3. Start tracking expenses. Every business-related receipt, from today forward. A simple spreadsheet or accounting app works. Keep records for 7 years.
4. Open a separate bank account for business income and expenses. This is not legally required for a sole prop, but it makes everything cleaner.
5. Consider voluntary EPF through i-Saraan — the 20% government incentive is free money, capped at RM500/year (RM5,000 over a lifetime).
6. Get a tax agent once your annual gross business income exceeds RM50,000. Their fee (RM500–1,500) is deductible, and they will almost certainly save you more than they cost.

Your side income is already taxable. The only question is whether you manage it proactively — claiming every legitimate deduction and staying compliant — or reactively, when LHDN sends a letter.

Amendment, 6 August 2026. This guide stated the i-Saraan government incentive as a 15% match. It is 20% of your voluntary contributions for the year, capped at RM500 a year and RM5,000 over a lifetime (or until you turn 60), per KWSP. The rate was raised from 15% to 20%. Any cap of RM250 or RM9,000, and any claim that the incentive is limited to people earning below RM4,000 or RM6,000 a month, was wrong. KWSP does not publish a monthly-income ceiling for i-Saraan. Contributing roughly RM2,500 in a year earns the full RM500.

Amendment, 11 October 2026. Structural change only: a short answer and a "Last updated" line were added at the top, section headings were rewritten as the questions they answer, and one question was added to the FAQ from this guide's own text. No figure, rule or source was changed. Every figure in the short answer already appears in the body of this guide. The tax bands it quotes are the ones in the table above, which match LHDN's resident-individual bands for Year of Assessment 2023, 2024 and 2025 (hasil.gov.my, last updated 26 June 2026), checked on 10 October 2026.

Amendment, 11 October 2026. Figure corrections, made separately from the structural change above. (1) Capital allowance for computers and IT equipment was given as "40% initial + 20% annual"; that was the wrong way round. LHDN's digital-business page gives a 20% initial allowance for all assets and a 40% annual allowance for computer and ICT equipment. (2) The Form B section now notes LHDN's 15-day grace period for Form e-B, to 15 July 2026 for YA2025 (Return Form Filing Programme for 2026); after that the form is treated as late from 1 July.

Amendment, 17 October 2026 (RM34,000). The first FAQ, the "Filing threshold" section, the declaration FAQ and the checklist step called RM34,000 after EPF the income at which you must file a return. LHDN's individual FAQ (hasil.gov.my, last updated 26 June 2026; sha256 4ca59d7d1188fc2c617ced2e018b9fc8c99ebf88ef0f5730491ea9dec15a974c, quote in docs/verification-log/faq-figures-pass2/evidence.md) says "you need to register a TIN if you are: Individual with single status who receive employment income in more than RM34,001 per year (after EPF deduction)"; that is a registration threshold. Whether you must file a return turns on section 77 of the Income Tax Act 1967 (taxable income for the year, or taxable income, a return or a filing requirement in an earlier year). Those passages now say so, and the sentence that most full-time employees already exceed the "threshold" is removed. Business owners must register with LHDN even at a loss, per the same FAQ.

Amendment, 17 October 2026 (section 77 wording). The RM34,000 passages now give the full section 77 test as LHDN's FAQ states it: taxable income for the year, or, without it, taxable income, a return or a filing requirement in an earlier year.

Amendment, 17 October 2026 (company secretary cost). The "Almost always start as a sole proprietor" passage gave company secretary fees of RM1,200–2,400 a year. That range had no source and is removed: fees vary by firm, so get quotes. The RM1,500–3,000 setup range was not re-checked. The first FAQ and the paragraph after the "Almost always start as a sole proprietor" passage (the one beginning "The Sdn Bhd conversation starts…") also called 17% "the SME corporate rate"; under paragraph 2A of Schedule 1 to the Income Tax Act 1967 a qualifying SME pays 15% on the first RM150,000, 17% on RM150,001 to RM600,000 and 24% above, so both now give 15% and 17%, as the sole proprietor vs Sdn Bhd guide does. (The 17 October 2026 note originally placed the second instance in the "Almost always start as a sole proprietor" passage itself; it was in the next paragraph, and this note corrects that description.)

Amendment, 17 October 2026 (audit and setup cost). The "Almost always start as a sole proprietor" passage said an Sdn Bhd "requires audited accounts" and cost "RM1,500–3,000 to set up". Neither is what the primary sources say. Section 267(1) of the Companies Act 2016 (Act 777, AGC text as at 1 August 2022) says "A private company shall appoint an auditor for each financial year of the company", and subsection 267(2) lets the Registrar exempt a private company. SSM's Practice Directive 10/2024 (16 December 2024, applying to financial statements with annual periods commencing on or after 1 January 2025) exempts a company that meets at least two of three tests on revenue, total assets and number of employees, with thresholds that rise in phases (RM1,000,000 / RM1,000,000 / 10 employees, then RM2,000,000 / RM2,000,000 / 20, then RM3,000,000 / RM3,000,000 / 30). The passage now says that, and the full wording is in the sole proprietor vs Sdn Bhd guide. The RM1,500–3,000 setup range had no source and is removed; SSM's own fees are RM50 for name reservation and RM1,000 for incorporation of a company limited by shares, plus RM10 for sharing the company's data with agencies (SSM, Guidelines for the Incorporation of Local Companies under section 14 of the Companies Act 2016). Evidence and hashes: docs/verification-log/guide-followups-oct17/.

Amendment, 17 October 2026 (Budget 2027 note). Added a note after the introduction on the YA2027 relief and rates, the Lindung Kendiri relief and the SOCSO matching incentives (Budget 2027, tabled 9 October 2026). Each figure was checked against the Ministry of Finance PDF it cites (sha256 recorded in docs/verification-log/geo-trim-budget27-oct17/evidence.md; Budget 2027 data rows: individual-relief-12000, tax-rates-70k-150k, tax-top-bands-30pc-above-1m, socso-relief-lindung-kendiri, socso-matching-gig-self-employed). They are proposals or announcements, not law. No YA2025 or YA2026 figure, rule or source in this guide was changed.

Amendment, 25 October 2026 (CP500, record keeping and deadlines). These passages now match the wording our freelancer guide took after the 17 October 2026 re-check against the Income Tax Act 1967 (Act 53, AGC text as at 1 November 2023; evidence batch H). Corrected (CP500): the guide said a CP500 notice requires "bimonthly advance tax payments (every 2 months, starting in March)", and the two PCB answers (the FAQ and its visible copy) said "bimonthly advance tax payments" or "bimonthly advance payments"; section 107B leaves the times and amounts of instalments to LHDN's direction, so all three now say instalments at the times LHDN sets, and "starting in March" is removed. The penalty sentences ("a 10% penalty on the unpaid amount" and "a 10% penalty on each missed payment") now give s107B(3): an instalment still unpaid 30 days after its due date is increased by 10% of the unpaid amount; "apply to LHDN for a revision" now gives the s107B(2) variation, once by 30 June and once by 31 October. Corrected (record keeping): "LHDN requires you to keep records for 7 years from the end of the year of assessment" now gives s82(1): seven years from the end of the year to which the business income relates. Removed: the FAQ's "LHDN can audit this far back", because we hold no primary text for LHDN's time limit to raise an assessment. Held, now labelled: the Form BE deadline of 30 April and the Form B dates beside it (30 June, and 15 July with the e-Filing grace) are LHDN's 2026 filing programme as read on 11 October 2026 and not re-checked (hasil.gov.my returned a "URL blocked" page to us on 17 and 25 October 2026); "an extra 2 months" is now "more time". Evidence: docs/verification-log/followups-tax-epf-oct25/evidence.md. Also reworded: the "Not keeping receipts" mistake said "Just keep them for 7 years"; it now gives the s82(1) period (seven years from the end of the year to which the business income relates), as the record-keeping section does.
