For many small and medium-sized enterprises (SMEs), corporate tax can seem complicated — especially when business owners are focused on sales, customers, employees and daily operations.
However, tax mistakes can arise from simple issues such as poor record-keeping, misunderstanding deductible expenses or missing important deadlines.
A company’s accounting profit is also not automatically the same as its taxable profit. The tax computation may require adjustments based on the applicable tax rules.
Here are some common corporate tax mistakes that SMEs should avoid.
1. Assuming Every Business Expense Is Tax Deductible
One of the most common misconceptions is:
“If the company paid for it, the company can claim it as a tax deduction.”
This is not necessarily the case.
An expense recorded in the company’s financial statements may require a tax adjustment if it does not qualify for deduction under the relevant tax rules.
Examples of expenses that may require further tax review include:
- Private or personal expenses
- Certain entertainment expenses
- Fines and penalties
- Expenses that are not wholly and exclusively incurred in the production of income
Therefore, businesses should not simply assume that every expense in the profit and loss account is deductible.
2. Treating Accounting Profit as Taxable Profit
Another common mistake is calculating corporate tax directly based on the profit shown in the financial statements.
For example, a company may have:
Accounting profit: RM100,000
But this does not necessarily mean that RM100,000 is the final amount subject to tax.
The tax computation may involve adjustments for items such as:
- Non-deductible expenses
- Tax incentives
- Other tax adjustments
The company’s tax computation should therefore be prepared based on the applicable tax rules rather than simply applying the tax rate to accounting profit.
HASiL’s Company Return Form requires companies to report statutory income, total income and chargeable income, illustrating that the tax calculation involves more than simply reporting accounting profit.
3. Confusing Depreciation With Capital Allowances
This is particularly common among SMEs that purchase equipment, machinery, computers or other business assets.
For accounting purposes, a company may recognise depreciation on an asset over its useful life.
For tax purposes, however, qualifying capital expenditure may be considered for capital allowances under the relevant tax provisions.
Therefore:
Accounting treatment: Depreciation
Tax treatment: Capital allowance, where applicable
These are not the same thing.
Companies should maintain an updated fixed asset register and retain invoices and other supporting documents for asset purchases.
HASiL’s company tax materials provide specific schedules for capital allowances and balancing charges under Schedule 3, demonstrating the separate treatment required for tax purposes.
4. Poor Record-Keeping
Good tax compliance starts with good accounting records.
Businesses sometimes keep only basic invoices and bank statements while failing to properly maintain supporting documents for transactions.
Important records may include:
- Sales invoices
- Purchase invoices
- Bank statements
- Loan documents
- Supporting documents for tax adjustments
Poor documentation can make it difficult to establish whether an expense is genuine, business-related and properly recorded.
HASiL’s company return documentation states that records and documents used in tax computation should be retained for seven years for reference and examination.
5. Mixing Personal and Business Expenses
SME owners often use company funds for various expenses, particularly when the business is closely managed by the owner.
This can create accounting and tax problems when personal expenses are recorded as business expenses.
Examples may include:
- Family expenses
- Personal travel
- Private vehicle expenses
Keeping personal and business expenses separate makes the company’s accounts easier to understand and helps reduce unnecessary tax adjustments.
A good practice is to use company bank accounts and payment methods primarily for genuine business transactions and maintain proper documentation for business expenses.
6. Forgetting to Review Director and Shareholder Transactions
In owner-managed companies, transactions between the company and its directors or shareholders are common.
These may include:
- Director advances
- Amounts owing by directors
- Amounts owing to directors
These balances should be properly recorded and reviewed.
Leaving director or shareholder balances unreconciled can create questions during the preparation of the financial statements and tax computation.
7. Not Updating the Tax Computation After Audit Adjustments
This is an important issue for companies that prepare their tax computation after the audit.
Suppose the company’s draft accounts show a profit of RM150,000.
After the audit, adjustments are made and the final profit becomes RM165,000.
If the tax computation is still based on the original draft figures, the company’s tax position may not be properly aligned with the final financial statements.
Therefore, after the audit is completed, companies should check that:
- The tax computation uses the final accounting figures
- Audit adjustments have been incorporated
Good coordination between the accounting, audit and tax processes can help prevent unnecessary corrections.
8. Missing Tax Submission and Payment Deadlines
A company may have a correct tax computation but still face problems if the relevant filing or payment deadlines are missed.
Companies should maintain a tax compliance calendar covering matters such as:
- Form C submission
- CP204 instalments
- CP204A revisions, where applicable
- Other applicable tax submissions
Deadlines should be monitored throughout the year rather than only when the annual accounts are being finalised.
The Form C itself is prescribed under Section 77A of the Income Tax Act 1967.
9. Ignoring Tax Instalments and CP204
Some SMEs focus heavily on the final tax payable and overlook their tax instalment obligations during the year.
Companies should monitor their tax estimates and instalment payments instead of waiting until the final tax computation is prepared.
If the company’s business performance changes significantly, management should also consider whether its tax estimate needs to be reviewed in accordance with the applicable requirements.
This can help avoid an unexpected tax cash-flow burden at the end of the year.
10. Ignoring Related-Party Transactions
Transactions between related companies, directors, shareholders or other related parties should be properly identified and recorded.
Examples include:
- Management fees
- Loans
- Purchases and sales
Depending on the circumstances, transfer pricing and other tax requirements may need to be considered.
Companies should therefore inform their tax adviser or accountant when significant related-party transactions take place rather than waiting until the tax computation is being prepared.
How SMEs Can Avoid These Mistakes
Good tax compliance does not necessarily require complicated procedures.
SMEs can start with a few simple practices:
Keep business and personal expenses separate
Use dedicated company accounts and payment methods for business transactions.
Maintain proper supporting documents
Keep invoices, receipts, bank statements and other relevant records in an organised manner.
Reconcile accounts regularly
Do not wait until year-end to discover unexplained differences.
Review major transactions early
Large asset purchases, loans, related-party transactions and unusual income should be reviewed before the tax computation is prepared.
Keep track of deadlines
Maintain a tax calendar for submissions, instalments and payments.
Communicate changes to your accountant or tax agent
Your accountant or tax agent can only consider the correct tax treatment if they know about significant transactions and changes in the business.
