Managing expenses is more than just keeping costs under control—it’s also a critical part of tax planning. In Singapore, businesses that understand what qualifies as deductible for tax purposes can significantly lower their taxable income, resulting in considerable savings. However, many companies either overlook or misclassify their expenses, missing out on valuable business tax deductions in Singapore they are entitled to claim.
This article explores the main types of allowable business expenses in Singapore and offers practical insights to help businesses strengthen their corporate tax savings strategies while staying compliant.
Salaries and CPF Contributions: Claiming Employment-Related Expenses
Employee remuneration is one of the most common deductible items. Salaries and wages paid to employees, including directors who are on the payroll, are deductible for tax purposes as long as they are incurred wholly and exclusively in the production of income. In addition, mandatory employer Central Provident Fund (CPF) contributions are also claimable.
To ensure eligibility, businesses must maintain proper documentation such as salary slips, CPF payment records, and employment contracts. These records support claims and ensure smooth processing during tax audits or reviews under Singapore tax services.
Office Rental and Utilities: Operational Costs That Qualify
The rental of office premises is another category that is tax deductible, provided the space is used exclusively for business operations. This includes coworking spaces, leased offices, and home offices (if used solely for work).

Utilities such as water, electricity, telephone bills, and internet charges are also allowable expenses. These operational costs must be directly related to the business and should not include any personal or non-business usage. Keeping detailed invoices and tenancy agreements is key to substantiating these claims.
Professional and Consultancy Fees: Strategic Expense Deductions
Fees paid to professionals, such as accountants, auditors, tax consultants, and legal advisors, are often overlooked but qualify as tax deductible. These services are essential for day-to-day operations, compliance, and strategic decision-making.
For instance, costs associated with small business accounting services in Singapore are deductible if they are part of routine business operations or required for regulatory compliance. Legal fees relating to business operations, such as contract reviews or corporate structuring, also fall into this category.
Marketing and Advertising: Investments That Drive Growth
Many companies invest heavily in marketing to grow their brand and increase revenue, and these investments can also yield tax advantages.
Marketing and advertising costs, whether for social media campaigns, Google Ads, printed materials, or public relations efforts, are deductible for tax purposes as long as they are aimed at promoting the business or generating revenue.
Even sponsorships or promotional events can qualify, provided they are directly related to income generation. Businesses should retain receipts, contracts with agencies, and campaign reports to validate these expenses as part of their corporate tax savings strategies.
Maximising Deductions Through Smart Tax Planning
Understanding what qualifies as deductible for tax purposes is essential for any business aiming to reduce its tax burden and operate more efficiently. By recognising and claiming these IRAS-allowable expenses, companies in Singapore may benefit from available tax deductions and better manage their overall financial position.
Engaging professionals offering accounting services in Singapore can offer guidance in navigating tax requirements and assist in preparing tax computations that are in line with IRAS guidelines.
