Your company pays for a meal, a laptop, a car expense or a professional service. The payment appears in the bank statement, the receipt is available, and the transaction has been recorded in the accounts.
So why might your accountant say that it is not tax deductible?
The answer is that an expense being paid by the company does not automatically make it deductible for corporate income tax purposes. Accounting and tax follow different rules, and the distinction becomes important when your company’s tax computation is prepared.
Here are some situations Singapore SME owners may encounter.
👁️🗨️ At a Glance
- Company payment is not proof of tax deductibility. The purpose and nature of the expense matter.
- A genuine business expense can still be disallowed. Some expenditure is specifically excluded under Singapore tax rules.
- Capital expenditure is treated differently. Qualifying assets may attract capital allowances instead of an ordinary expense deduction.
- Accounting profit is not necessarily taxable profit. Tax adjustments explain the difference.
1. The company paid for dinner. Was it a business expense?
Suppose a company director uses the company card to pay for dinner.
If the dinner was with a prospective customer to discuss business, it may qualify as a deductible entertainment expense.
But if the dinner was a family celebration unrelated to the company’s business, paying with the company card does not turn it into a business expense.
The receipt might look identical in both situations. What matters is why the expense was incurred, not whose card was used.
A mixed business-and-private occasion may require closer examination rather than automatically treating the entire bill as deductible.
💡 Prologue Tip
When recording entertainment expenses, keep enough information to establish the business purpose, such as who attended and the reason for the meeting. A receipt proves that money was spent. It does not necessarily establish why.
2. The company bought a laptop. Why is depreciation added back?
Suppose your company purchases a laptop for S$1,800 and records it as a fixed asset.
In the financial statements, the company may recognise depreciation over the laptop’s estimated useful life. Assuming a three-year useful life, straight-line depreciation would be S$600 annually.
However, depreciation is not deductible for Singapore corporate income tax purposes.
Does that mean the company receives no tax relief for the laptop?
Not necessarily.
Qualifying computers and laptops may be eligible for capital allowances, including a 100% write-off under the applicable rules.
This creates an important distinction:
- Accounting: The laptop is recorded as an asset, with depreciation recognised according to the applicable accounting policy.
- Tax: Accounting depreciation is added back, and qualifying capital allowances may be deducted instead.
The company may therefore receive tax relief, but through a different mechanism from the one used in its financial statements.
💡 Prologue Tip
Do not assume that an expense has been disallowed permanently simply because it was added back in the tax computation. Check whether another form of tax relief is available.
3. The director used a personal car for company business. Surely that is deductible?
Suppose a director drives an S-plated private car to meet a customer and claims reimbursement for petrol and parking.
The trip was genuinely for business.
Nevertheless, Singapore’s tax rules generally disallow expenses relating to private cars, including petrol, parking, repairs and maintenance, even where the cars are used for business purposes.
The restriction also applies to reimbursement of such expenses.
This is an example of why business purpose alone is not always sufficient. An expense may relate to business activities but still fall within a specific statutory prohibition.
Different rules can apply to qualifying business transport services, commercial vehicles and employee transport allowances.
💡 Prologue Tip
IRAS distinguishes between reimbursement of private-car expenses and a transport allowance paid to an employee.
Private-car expense reimbursements are not deductible to the company, whereas a genuine staff transport allowance is deductible to the company but taxable as employment income in the employee’s hands.
The distinction matters when structuring staff transport payments. An allowance should not simply be used to relabel a reimbursement.
4. The company paid expenses before earning its first dollar. Are they lost?
Many new businesses incur expenses before receiving their first customer payment.
There may be office rental, utilities, subscriptions, professional fees and other costs involved in getting the business ready.
A common assumption is that none of these expenses can be claimed because the business has not yet earned revenue.
That is not necessarily correct.
Under Singapore’s income tax rules, certain qualifying expenses incurred before a business commences may be deductible. However, the treatment depends on when the business is considered to have commenced, the nature of the expenditure and the circumstances of the individual company.
IRAS provides guidance on determining the commencement date and on the tax treatment of expenses incurred before commencement, including a concession under Section 14R of the Income Tax Act 1947.
Importantly, the date of incorporation, the date of the first business receipt and the actual commencement of business are not necessarily the same.
Business owners should therefore not assume that all expenses incurred before their first sale are either deductible or disallowed.
For the applicable conditions, refer to IRAS: Tax Treatment of Business Expenses (A–F), under Expenses Incurred Before Commencement of Business.
💡 Prologue Tip
Keep pre-commencement expenses separately identifiable, together with their dates and supporting documents. This makes it easier to assess which expenses may qualify for deduction and in which Year of Assessment.
5. The company paid a fine. Why is it added back?
Suppose a company incurs a regulatory penalty and records it in its profit and loss account.
The payment is real. It reduces the company’s cash balance and accounting profit.
But statutory fines and penalties are generally not deductible for corporate income tax purposes.
Contrast that with ordinary qualifying professional fees incurred to meet statutory obligations, such as accounting, audit, corporate secretarial and tax compliance fees, which may be deductible.
Both types of expenditure can arise from operating a company. Their tax treatment is different.
The practical lesson is that an expense being necessary, unavoidable or actually paid does not, by itself, establish deductibility.
6. What happens when your accountant prepares the tax computation?
This is where the difference between accounting profit and taxable income becomes visible.
Consider a simplified example.
A company reports an accounting profit before tax of S$50,000.
Its expenses include:
- S$600 of depreciation on a qualifying laptop costing S$1,800;
- S$500 of private-car expenses;
- S$300 of statutory penalties.
Assume the company is entitled to claim S$1,800 in capital allowances on the laptop.
The tax adjustments would look like this:
| S$ | |
| Accounting profit before tax | 50,000 |
| Add back: Depreciation | 600 |
| Add back: Private-car expenses | 500 |
| Add back: Statutory penalties | 300 |
| Adjusted profit before capital allowances | 51,400 |
| Less: Capital allowances | (1,800) |
| Adjusted profit after capital allowances | 49,600 |
In this illustration, the adjusted profit after capital allowances is S$400 lower than the original accounting profit.
That does not mean every expense was deductible. The difference arises because the accounting depreciation and tax capital allowances are calculated differently, while the private-car expenses and penalties are disallowed.
In another year, or with different expenditure, the resulting figures could be quite different.
This is also not necessarily the company’s final chargeable income. Other adjustments, reliefs, exemptions and deductions may apply.
The important point is that a tax computation does not simply take the accounting profit and multiply it by 17%.
7. IRAS Tools to Help with Business Expense Deductibility and Tax Computation
IRAS provides digital resources to help companies assess the tax deductibility of business expenses and prepare their corporate income tax computations.
The Business Expense Deductibility Checker helps companies determine whether their business expenses are tax deductible, providing a useful starting point when assessing expenditure for tax purposes.
The Basic Tax Calculator guides companies through preparing tax computations and supporting schedules, with explanatory notes and validation checks.
These resources can help business owners better understand the tax treatment of their transactions.
However, the distinction between accounting and tax remains important. A deductibility check does not, by itself, establish whether a transaction has been correctly recorded in the accounts, whether the supporting information is sufficient, or whether other tax adjustments are required.
For example, identifying that depreciation is not tax deductible is only part of the exercise. The accountant must also consider whether the underlying asset qualifies for capital allowances and how the relevant amounts should be reflected in the tax computation.
Making the distinction
A company can pay for something without that payment being tax deductible.
An expense can be correctly recorded in the financial statements but require an adjustment in the tax computation.
And an amount added back for tax purposes may, in some cases, qualify for relief under a different provision.
Understanding these distinctions helps business owners make better decisions, maintain more useful accounting records and avoid assuming that every dollar spent by the company reduces its tax bill.
