Deferred Tax: What Singapore SMEs Should Know
28 September 2026
Editor: ET
For many Singapore business owners, tax is usually discussed in terms of what the company needs to pay to IRAS. But when financial statements are prepared, another concept can appear: deferred tax.
Deferred tax can seem technical at first, especially for smaller businesses that are more familiar with bookkeeping, GST and corporate income tax. However, understanding the basic idea can help business owners read their financial statements more confidently and understand why the tax expense shown in the accounts may not always match the tax payable to IRAS.
For SMEs, deferred tax is primarily an accounting concept. It does not simply mean that the company has delayed paying its tax.

What Is Deferred Tax?
Deferred tax generally arises because accounting rules and tax rules do not always recognise income, expenses, assets or liabilities at the same time.
Financial statements are prepared under the applicable financial reporting framework. ACRA notes that Singapore businesses should refer to the applicable financial reporting framework and Statement of Applicability when preparing financial statements. These frameworks include Singapore Financial Reporting Standards (SFRS(I)) and other applicable standards.
Tax, meanwhile, is calculated according to Singapore's tax legislation and IRAS requirements.
This timing difference can result in an accounting entry for deferred tax.
In simple terms, deferred tax helps financial statements reflect the future tax consequences of differences between the accounting carrying amount of an asset or liability and its tax treatment.
That sounds complicated, but the underlying idea is relatively straightforward: accounting and tax may recognise the same transaction differently or at different times.
Current Tax and Deferred Tax Are Different
One of the easiest ways to understand deferred tax is to separate it from current tax.
Current tax relates broadly to the tax payable on taxable income for the relevant period under Singapore tax rules.
Deferred tax relates to tax consequences that arise from temporary differences between accounting and tax treatment.
Therefore, a company's financial statements might show both current tax and deferred tax movements.
This does not necessarily mean the company has received a separate tax bill for deferred tax.
For business owners, this distinction matters when reading the profit and loss statement. The tax expense shown in the accounts may not be identical to the amount of tax that the company ultimately pays to IRAS for that period.
Why Do Temporary Differences Happen?
Temporary differences can arise in several ways.
One common example involves depreciation.
A company may depreciate an asset over its useful life for accounting purposes. For tax purposes, however, the company may claim capital allowances under Singapore's tax rules instead.
The accounting carrying amount of the asset can therefore differ from its tax base.
IRAS treats capital allowances separately from ordinary business expense deductions, and companies may claim qualifying capital allowances according to the relevant rules.
This difference can create a deferred tax consequence in the financial statements.
Other situations can also create temporary differences, including certain provisions, accrued expenses, lease accounting, asset valuations and other transactions where the accounting treatment and tax treatment occur at different times.
The exact treatment depends on the applicable accounting standard and the facts of the transaction.
Deferred Tax Assets and Liabilities
There are two terms business owners are likely to encounter: deferred tax asset and deferred tax liability.
A deferred tax liability generally represents future tax consequences associated with taxable temporary differences.
A deferred tax asset can arise from deductible temporary differences or certain tax losses and credits that may reduce taxable amounts in future periods, subject to the applicable recognition requirements.
However, a deferred tax asset is not automatically recognised simply because a company has experienced a tax loss.
The accounting framework includes recognition criteria, including considerations about whether sufficient future taxable profits are expected to be available against which the relevant amounts can be utilised.
This is one reason deferred tax calculations should not be treated as a simple bookkeeping formula.
A Simple Example
Imagine a Singapore SME purchases equipment for S$100,000.
For accounting purposes, the business may depreciate the equipment over five years. That could result in an accounting depreciation expense of S$20,000 per year, assuming a simple straight-line approach and no residual value.
For tax purposes, the company may instead receive capital allowances according to the applicable Singapore tax rules.
If the accounting depreciation and tax deduction occur at different rates or times, the accounting value of the equipment and its tax base may diverge.
That difference can create a deferred tax balance.
The important point is that the company has not necessarily made an error. The difference can simply reflect two different sets of rules being applied for different purposes.
Why Deferred Tax Matters to SMEs
Deferred tax can be particularly relevant when an SME is becoming more sophisticated in its financial reporting.
A small business may initially focus primarily on bookkeeping, GST and corporate income tax filing. As the business grows, it may need more detailed financial reporting for investors, banks, shareholders, group reporting or other stakeholders.
Expede Tech's accounting services include financial statements, profit and loss reporting, bookkeeping and corporate tax compliance for Singapore businesses. Its approach connects accounting information with wider compliance and financial management rather than treating each task as completely separate.
Understanding deferred tax can form part of that broader financial picture.
It can help owners ask better questions when reviewing their accounts:
Why is the accounting tax expense different from tax payable?
Has the company recognised deferred tax on significant assets?
Are tax losses or temporary differences being accounted for correctly?
Have accounting and tax treatments been reconciled?
Are there significant tax-related balances that management should understand?
Deferred Tax Does Not Mean Paying Less Tax
This is an important misconception to avoid.
A deferred tax asset or liability is primarily an accounting presentation of future tax consequences. It does not automatically create a tax saving, refund or reduction in the company's current tax bill.
Singapore corporate tax remains governed by the relevant tax rules administered by IRAS.
For example, IRAS explains that taxable income and deductible expenses are determined under Singapore tax rules, while accounting records provide the underlying information needed for accurate tax reporting.
Business owners should therefore avoid interpreting a deferred tax movement as a direct change to the amount they need to pay immediately.
Keep Accounting and Tax Records Connected
Deferred tax calculations depend on reliable financial and tax information.
This makes good bookkeeping particularly important.
Businesses should maintain clear records of:
Fixed assets and depreciation
Capital allowances
Tax losses
Provisions and accruals
Lease arrangements
Significant accounting adjustments
Tax computations
Financial statements
IRAS requires companies to maintain proper accounting and supporting records for at least five years from the relevant Year of Assessment.
When records are organised throughout the year, accountants can more easily identify differences between accounting and tax treatments during the financial reporting process.
When Should Business Owners Review Deferred Tax?
Deferred tax should generally be considered when preparing financial statements under a framework that requires it.
It can become especially relevant when a business:
Purchases significant assets
Expands into new markets
Records substantial tax losses
Enters into leases
Changes its accounting policies
Becomes part of a larger group
Prepares financial statements for investors or lenders
Rather than waiting until year-end to discover unexpected accounting adjustments, SMEs can discuss significant transactions with their accounting professionals when they occur.
That can make financial reporting more predictable and reduce last-minute reconciliation work.

Making Deferred Tax Easier to Understand
Deferred tax may sound like a subject reserved for large corporations, but the underlying concept can appear in the financial statements of businesses of different sizes when the applicable reporting framework requires it.
For Singapore SMEs, the key is not to memorise every accounting rule. It is to understand the difference between accounting profit, taxable income, current tax and deferred tax.
Expede Tech's technology-enabled accounting approach combines bookkeeping, financial reporting and tax compliance support, helping businesses maintain more organised financial information as their reporting needs develop.
Ultimately, deferred tax is about connecting today's financial statements with the future tax consequences of transactions already recorded.
For business owners, understanding that connection can make financial reports less intimidating—and provide a clearer view of what the company's numbers are really saying.
