Overview: How Sole Proprietors are Taxed in Malaysia
If you run an Enterprise or Sole Proprietorship in Sabah, your business does not exist as an independent legal entity from yourself. Unlike a Sdn Bhd, your net business profits are treated as personal taxable income and assessed under Malaysian personal income tax rates.
Key Characteristics:
- Tax Regime: Progressive personal income tax brackets ranging from 0% up to 30% [VERIFY: Budget 2027 proposed top rate above RM1,000,000].
- Filing Form: Form B (Individual with Business Income).
- Personal Reliefs: You can deduct eligible personal reliefs (such as standard individual relief proposed to rise from RM9,000 to RM12,000 under Budget 2027 [VERIFY], EPF/life insurance, and medical reliefs) directly from your total chargeable income.
Forms & Annual Filing Requirements
Sole proprietors carrying on a business must submit their annual tax return via LHDN e-Filing using Form B.
- Accounting Books: Even though an audit is not required by law for sole proprietorships, you are legally required by the Inland Revenue Board (LHDN) under the Income Tax Act 1967 to maintain organized books, receipts, and invoices for at least 7 years [VERIFY].
- Form B Submission: Due annually on 30 June following the end of the calendar year (or the official e-Filing grace period extension granted by LHDN).
- CP500 Bi-Monthly Installments: If LHDN determines your business generates consistent income, they may issue a CP500 notice requiring you to pay tax installments in six bi-monthly payments starting March.
Common Deductible Business Expenses
Under Section 33(1) of the Income Tax Act 1967, an expense is tax-deductible if it is wholly and exclusively incurred in the production of gross income.
Typically Allowable Deductions:
- Commercial Rent & Utilities: Office, shop lot, or warehouse rental in Sabah, along with electricity, water, and commercial internet bills.
- Employee Wages & Statutory Contributions: Staff salaries, EPF, SOCSO, and EIS payments for employees (note: your own proprietor drawings or owner salary are not tax-deductible).
- Purchases & Cost of Goods Sold: Direct materials, inventory purchases, and freight/carriage inward costs.
- Professional & Accounting Fees: Fees paid to accountants, tax agents, and business advisors for book-keeping and statutory compliance.
- Repair & Maintenance: Routine repairs to business premises and operating machinery.
Non-Deductible (Disallowable) Expenses:
- Personal or domestic expenses (e.g. personal groceries, private vehicle use).
- Fines and penalties imposed by local municipal councils (e.g. DBKK, MPKK) or statutory bodies.
- Capital expenditure on equipment (these must be claimed via Capital Allowances rather than direct expense deductions).
Preparing for e-Invoicing
Under Malaysia’s ongoing e-Invoicing rollout, all sole proprietorships and enterprises in Sabah will eventually be required to issue validated electronic invoices or consolidated e-invoices for consumer transactions.
- If your annual turnover is below the eventual exemption threshold (currently subject to confirmation between RM1,000,000 and RM3,000,000 [VERIFY]), you may be exempt or qualify for simplified reporting.
- A relaxation period for small businesses with turnover up to RM5,000,000 has been reported as extended to 31 December 2027 [VERIFY].
