Understanding Deductible Business Expenses in Singapore: What Can Companies Claim?
Running a business in Singapore comes with many operating costs, but not every expense qualifies for tax deduction. Understanding which business expenses are deductible can help companies reduce taxable income, improve cash flow, and stay compliant with Inland Revenue Authority of Singapore (IRAS) regulations.
According to IRAS, deductible business expenses must generally be incurred “wholly and exclusively” for income-producing activities. Expenses must also be revenue in nature and properly supported with documentation. This guide explains the common deductible expenses Singapore companies can claim and how businesses can maximise their tax efficiency legally.
What Are Deductible Business Expenses?
Deductible business expenses are costs directly related to generating business income. These expenses reduce a company’s taxable profits and ultimately lower corporate tax payable.
To qualify for deduction under Singapore tax rules, expenses generally must:
- Be incurred solely for business purposes
- Be revenue-related instead of capital-related
- Be properly documented with invoices and receipts
- Not fall under non-deductible categories prohibited by IRAS
Examples of deductible expenses include salaries, office rental, utilities, marketing costs, accounting fees, and software subscriptions.
Employee Salaries and CPF Contributions
Staff-related expenses are among the most commonly claimed deductions for Singapore businesses.
Companies may claim:
- Employee salaries and wages
- Bonuses and commissions
- Mandatory CPF contributions
- Staff training expenses
- Recruitment costs
Director salaries are also deductible if they are part of normal business operations and properly recorded.
Businesses should maintain:
- Employment contracts
- CPF payment records
- Payslips
- Payroll summaries
Proper documentation helps support claims during audits or tax reviews.
Office Rental and Utility Expenses
Office rental expenses used for business purposes are generally tax deductible in Singapore.
This includes:
- Commercial office rental
- Co-working space fees
- Warehouse rental
- Utility bills such as electricity and water
- Internet and telephone charges
If a home office arrangement is used, only the business-use portion may qualify for deduction. Personal expenses cannot be claimed.
Marketing and Advertising Costs
Marketing expenses incurred to promote products or services are usually deductible.
Examples include:
- Social media advertising
- Google Ads campaigns
- Website development and maintenance
- Branding and design costs
- Promotional events
- Printing brochures and flyers
These expenses must be directly connected to revenue generation activities. Companies should retain invoices, advertising contracts, and campaign reports as supporting evidence.
Professional and Accounting Fees
Professional services are essential for business operations and tax compliance. Many related costs are deductible under IRAS guidelines.
Claimable professional fees may include:
- Accounting and bookkeeping services
- Tax advisory services
- Audit fees
- Corporate secretarial services
- Legal consultation fees for business matters
Working with experienced accounting professionals can help businesses identify eligible deductions and avoid filing errors.

Software and Technology Expenses
Digital tools are increasingly necessary for modern businesses, and many software-related costs qualify for deductions.
Examples include:
- Accounting software subscriptions
- CRM systems
- Cloud storage services
- Cybersecurity solutions
- Productivity software
- E-commerce platform subscriptions
As long as these tools are used for business operations, companies may generally claim them as deductible expenses.
Business Travel and Transportation
Business-related travel expenses can also be deductible when incurred for income-producing activities.
Examples include:
- Airfare for business trips
- Hotel accommodation
- Taxi and transport fares
- Client meeting travel expenses
However, personal travel expenses are non-deductible. Companies should keep travel itineraries, receipts, and business purpose records to substantiate claims.
Non-Deductible Expenses Businesses Should Avoid Claiming
Not every expense qualifies for tax deduction. Common non-deductible expenses include:
- Personal expenses
- Private vehicle expenses for certain cars
- Fines and penalties
- Capital expenditure on fixed assets
- Entertainment unrelated to business activities
Improper claims may result in penalties or tax adjustments during IRAS audits.
Importance of Proper Record Keeping
Good record keeping is essential for successful tax claims.
Businesses should retain:
- Receipts and invoices
- Contracts and agreements
- Payroll records
- Bank statements
- Expense reports
IRAS generally requires records to be kept for at least five years. Maintaining organised financial records can simplify tax filing and reduce compliance risks.
