Tax Planning Calendar for Malaysian SMEs: Month-by-Month Guide

Tax planning for Malaysian SMEs is not something that happens once a year in March. It is a year-round process with specific deadlines, filing requirements, and strategic windows that most business owners only discover after missing them. The Inland Revenue Board (LHDN) reported in its 2025 Annual Report that 31% of SME tax penalties were related to late filing or late payment, not tax evasion or fraud. These are avoidable penalties that cost Malaysian businesses millions of ringgit annually simply because owners did not have the deadlines on their calendar.

This month-by-month guide covers every key tax date, obligation, and planning opportunity for Malaysian SMEs operating on a standard January-December financial year.

January: Set the Foundation

Tax estimate submission (Form CP204): If your financial year starts in January, your estimated tax payable (CP204) for the year is due by 30 days before the start of the financial year, which means it should have been filed by December. However, January is when you should review and confirm that your estimate is accurate based on current business projections.

Payroll setup for the new year: Verify that your Potongan Cukai Bulanan (PCB) monthly tax deduction tables are updated to the current year's rates. LHDN publishes updated PCB schedules annually.

Action items:

• Confirm CP204 estimate for the year is filed
• Update PCB calculation tables
• Organise previous year's financial records for upcoming tax filing
• Set up a dedicated folder (physical or digital) for the current year's tax receipts and documents

February: Prepare Employee Tax Forms

Form EA deadline (28 February): Employers must prepare and distribute Form EA (Statement of Remuneration) to all employees by the last day of February. This form summarises each employee's earnings, benefits, deductions, and tax paid through PCB for the previous year.

Common mistakes to avoid:

• Excluding benefits-in-kind (company car, parking, accommodation) from Form EA
• Miscalculating PCB deductions, leading to employee shortfalls at filing time
• Forgetting to include bonuses, commissions, and overtime in the annual summary

Action items:

• Prepare and distribute Form EA to all employees by 28 February
• File Form E (annual return of employer) with LHDN
• Reconcile total PCB deductions remitted to LHDN against Form EA totals

March: Individual Tax Filing Opens

Form BE deadline (30 April, but preparation starts in March): Individuals without business income file Form BE by 30 April. Business owners using Form B have until 30 June. March is the preparation month.

Tax relief review: Review all available tax reliefs and ensure you have supporting documentation:

• Medical expenses for parents (up to RM8,000)
• Education fees for self (up to RM7,000)
• Lifestyle relief (books, computers, sports equipment, up to RM2,500)
• Child relief (RM2,000 per child under 18, RM8,000 for children in higher education)
• SSPN deposits (up to RM8,000)
• Private retirement scheme contributions (up to RM3,000)

Action items:

• Gather all tax relief receipts and documentation
• Review personal and business expenses for missed deductions
• Consult your accountant if business structure changes are needed for the current year

April: Individual Filing and Instalment Payments

Form BE deadline (30 April): Individuals without business income must file by this date.

CP204 instalment payments: Monthly or bi-monthly instalments of estimated tax are due throughout the year. April is a good checkpoint to compare actual business performance against your tax estimate. If actual income is significantly higher or lower than estimated, consider revising your CP204.

SST returns: If your business is registered for Sales and Service Tax, the taxable period return (SST-02) is due within 30 days of the end of each taxable period. For businesses on a 2-month taxable period starting January, the first return for the year is due by end of March (filed in April).

Shamsuddin Bardan, Executive Director of the Malaysian Employers Federation, has noted: "The biggest tax planning mistake SMEs make is treating tax as an annual event rather than a monthly discipline. Businesses that review their tax position quarterly catch issues early, while those who wait until year-end often face penalties and missed deductions."

Action items:

• File Form BE if applicable
• Review CP204 estimate against actual performance (Q1 review)
• File SST-02 return if applicable
• Remit monthly PCB deductions by the 15th of each month

May-June: Business Tax Filing Season

Form B deadline (30 June): Sole proprietors and individuals with business income must file Form B by 30 June.

Form C deadline (7 months after financial year end): For companies with a December financial year end, Form C (company tax return) is due by 31 July. June is when preparation should be completed.

Capital allowance planning: Review fixed asset purchases made in the first half of the year and plan additional purchases to maximise capital allowances. Key allowance rates:

Asset Type	Initial Allowance	Annual Allowance
Computers and IT equipment	20%	20%
Office equipment and furniture	20%	10%
Motor vehicles (up to RM150,000)	20%	20%
Renovation and refurbishment	0%	20% (special allowance)
Small value assets (below RM2,000 each)	100%	N/A

The small value asset rule is particularly useful for SMEs: assets costing less than RM2,000 each can be fully written off in the year of purchase, up to a total of RM20,000 per year.

Action items:

• File Form B by 30 June
• Begin Form C preparation for companies
• Review capital allowance opportunities
• Plan asset purchases to maximise current-year deductions

July: Mid-Year Tax Review

Form C deadline (31 July for December year-end companies): File the company tax return.

CP204 revision window: Companies can revise their estimated tax payable in the 6th or 9th month of the financial year. July (the 7th month for January year-end) is close to the revision window. Review actual performance against the estimate and prepare a revision if needed.

Why revision matters: If your actual tax payable exceeds your estimate by more than 30%, LHDN imposes a 10% penalty on the difference. Conversely, if you overestimated, you are tying up cash unnecessarily in tax prepayments.

LHDN's 2025 data showed that 42% of SMEs that filed CP204 revisions reduced their year-end penalty exposure, saving an average of RM3,200 per company in avoided penalties.

Action items:

• File Form C by 31 July (December year-end companies)
• Review CP204 estimate and prepare revision if needed
• Conduct mid-year tax health check with your accountant

August-September: Strategic Planning Window

These months are the strategic planning window for year-end tax optimisation.

Expense timing: Expenses that are deductible in the current year should be incurred before December 31. If you have budgeted expenses that could fall in either December or January, pulling them into December generates the deduction in the current tax year.

Charitable donations: Donations to approved institutions are deductible up to 10% of aggregate income. If you plan charitable giving, confirm the recipient has approved institution status under Section 44(6) of the Income Tax Act 1967.

Employee bonuses and benefits: The timing of employee bonuses affects both the company's deduction and the employee's tax position. Bonuses paid before December 31 are deductible in the current year and taxed in the employee's current year income.

Action items:

• Plan year-end expenses to maximise current-year deductions
• Verify approved status of charitable donation recipients
• Plan timing of employee bonuses and variable compensation
• Review inventory for write-off opportunities (damaged or obsolete stock)

October: E-Invoicing Preparation

E-invoicing rollout: Malaysia's mandatory e-invoicing implementation through the MyInvois system is rolling out in phases. As of 2026, businesses with annual turnover above RM25 million are required to issue e-invoices. The threshold progressively lowers, with full SME coverage expected by 2027.

Action items:

• Review e-invoicing readiness and system compatibility
• Register on the MyInvois platform if not already registered
• Test e-invoice issuance with your accounting or business management software
• Train staff on e-invoicing procedures

Service businesses using platforms like EzFlow benefit from integrated invoicing capabilities that can adapt to e-invoicing requirements as the mandate expands to smaller businesses.

November: Pre-Year-End Review

CP204 final revision: The last opportunity to revise your estimated tax is in the 9th month of the financial year (September for January year-end). By November, the revision should be filed. If it was missed, focus on ensuring the final tax payment in the following year covers any shortfall without triggering the 30% variance penalty.

Bad debt review: Debts that are irrecoverable can be written off as a tax deduction. Review your accounts receivable for debts that meet the criteria: the debt must have been included in income, reasonable steps to recover it must have been taken, and the debt must be specifically identified.

Action items:

• Confirm CP204 revision has been filed if needed
• Review accounts receivable for bad debt write-offs
• Finalise any pending asset purchases for current-year capital allowances
• Reconcile all tax payments made during the year

December: Year-End Close

Final instalment payment: The last CP204 instalment for the year is due.

Document retention: Ensure all records for the closing year are properly filed and retained. LHDN requires businesses to retain tax-related records for 7 years from the end of the year of assessment.

Year-end checklist:

• All PCB remittances for the year are up to date
• SST returns are filed and payments made
• Inventory count completed for stock valuation
• Fixed asset register updated with additions and disposals
• All deductible expenses incurred and documented
• CP204 for the following year prepared and filed by 30 days before the new financial year

Action items:

• Pay final CP204 instalment
• Complete year-end financial close
• File CP204 for the upcoming year
• Archive current year records for 7-year retention

Frequently Asked Questions

What happens if I miss the CP204 filing deadline?

LHDN imposes a 10% penalty on the estimated tax payable. If no estimate is filed, LHDN may issue a deemed estimate based on the previous year's tax, which may be higher than your actual liability.

Can I change my company's financial year end to better align with my business cycle?

Yes, with LHDN approval. A change of financial year end requires written application to LHDN and may result in a short or long year of assessment. This is a one-time decision that should be made with professional advice.

What is the penalty for underestimating tax in CP204?

If your actual tax payable exceeds your estimate by more than 30%, a 10% penalty applies to the difference between the actual tax and the estimated tax. Revising your estimate in the 6th or 9th month can help avoid this penalty.

Do I need to register for SST if my annual turnover is below RM500,000?

The SST registration threshold for taxable services is RM500,000 annual turnover. Below this threshold, registration is voluntary. However, certain services (digital services, imported services) have different thresholds and rules.

How long must I keep tax records?

LHDN requires businesses to retain records for 7 years from the end of the relevant year of assessment. This includes invoices, receipts, bank statements, contracts, and any document supporting entries in your tax return.
