Advertising Tax Deduction in Singapore: What Marketers Can Claim in 2026

Every dollar your Singapore business spends on marketing is an investment — and much of that investment is tax-deductible. The Inland Revenue Authority of Singapore (IRAS) allows businesses to deduct advertising and marketing expenses against taxable income, subject to specific rules under the Income Tax Act 1947. Understanding these rules can significantly reduce your effective marketing costs and improve campaign ROI.

However, not every marketing expense qualifies for a deduction. IRAS draws important distinctions between revenue expenditure (deductible) and capital expenditure (generally not deductible), between expenses incurred in producing income (deductible) and expenses that are personal or unrelated to business operations (not deductible). Getting these distinctions wrong can result in disallowed claims, back taxes, and penalties.

This guide covers the IRAS treatment of common marketing and advertising expenses in Singapore for the Year of Assessment 2027 (financial year 2026), with practical guidance on maximising your legitimate deductions while maintaining full compliance with tax law.

IRAS Treatment of Marketing Expenses

Under Section 14(1) of the Income Tax Act 1947, a deduction is allowed for all outgoings and expenses wholly and exclusively incurred in the production of income. For marketing expenses to qualify, they must meet three conditions: the expense must be revenue in nature (not capital), it must be incurred in the production of income (not for private purposes), and it must not be specifically prohibited under the Income Tax Act.

IRAS takes a substance-over-form approach when assessing marketing deductions. This means the authority looks at the true nature and purpose of the expenditure, not just how it is labelled in your accounts. A payment described as “advertising” in your books is not automatically deductible — its actual nature determines the tax treatment.

Key principles that guide IRAS’s assessment of marketing expenses:

Revenue vs capital: Ongoing advertising and promotional expenses that maintain or promote an existing business are revenue expenditure and deductible. Expenditure that creates a lasting asset or advantage — such as building a brand from scratch for a new business — may be treated as capital expenditure and disallowed.
Wholly and exclusively: The expense must be incurred entirely for business purposes. Mixed-purpose expenditure — such as a corporate event that serves both business entertainment and personal socialising — may be partially disallowed.
Production of income: The expense must relate to income-producing activities. Marketing expenses for activities that do not generate revenue — such as promoting a charitable cause without commercial benefit — are not deductible under Section 14(1), although they may qualify for deduction under other provisions such as Section 37 (charitable donations).

Understanding these principles helps marketing teams and finance departments work together to structure marketing expenditure in a way that maximises legitimate tax deductions. Our digital marketing services team works with businesses to plan campaigns with both performance and tax efficiency in mind.

Deductible Marketing Expenses

The following categories of marketing expenses are generally deductible under Singapore tax law, provided they meet the conditions outlined above:

Digital advertising: Spending on Iklan Google, Meta (Facebook and Instagram) advertising, LinkedIn advertising, TikTok ads, programmatic display advertising, and other digital advertising platforms is fully deductible as revenue expenditure. This includes the cost of ad spend, platform fees, and agency management fees.
Search engine optimisation: Fees paid to SEO agencies or consultants for ongoing SEO services — including technical audits, content optimisation, link building, and keyword research — are deductible as revenue expenditure. These are recurring services that maintain your online visibility, not one-off capital investments.
Content creation: Costs of producing marketing content — blog articles, videos, infographics, whitepapers, case studies, and social media content — are deductible. This includes fees paid to content marketing agencies, freelance writers, photographers, and videographers.
Email marketing: Subscription fees for email marketing platforms (Mailchimp, HubSpot, Klaviyo), costs of email template design, and fees for email marketing services are deductible.
Social media management: Fees for perkhidmatan pemasaran media sosial, social media management tools, and influencer marketing payments are deductible as revenue expenditure.
Print and outdoor advertising: Costs of newspaper advertisements, magazine placements, billboard rentals, MRT advertising, bus advertising, and other traditional media placements are deductible.
Trade show and event marketing: Booth rental, display materials, promotional giveaways (subject to the entertainment expense rules), and event sponsorship costs related to trade shows and industry events are generally deductible.
Public relations: Fees paid to PR agencies for media relations, press release distribution, crisis communications, and reputation management are deductible.
Marketing software and tools: Subscription fees for marketing automation platforms, CRM systems, analytics tools, A/B testing platforms, and project management software used by marketing teams are deductible.

Non-Deductible Marketing Expenses

Certain marketing-related expenses are not deductible under Singapore tax law, either because they are capital in nature, not incurred in the production of income, or specifically excluded by the Income Tax Act:

Entertainment expenses: Under Section 17(1)(b) of the Income Tax Act, entertainment expenses are generally not deductible. This includes client entertainment (meals, drinks, hospitality), corporate gifts, and event hospitality. However, there are exceptions — entertainment provided to employees, entertainment at trade or industrial exhibitions open to the public, and promotional gifts bearing the company’s name or branding (valued at SGD 50 or less per item) are deductible.
Capital brand-building expenditure: Costs of developing a brand from scratch — including trademark registration fees, brand strategy consulting fees for a new brand, and initial brand identity creation — may be treated as capital expenditure. However, the distinction between capital and revenue brand expenditure is nuanced and depends on the specific circumstances.
Private or non-business purposes: Marketing expenses that are not related to business income production are not deductible. For example, advertising for a director’s personal event or promoting a cause unrelated to the business does not qualify.
Penalties and fines: Any fines or penalties arising from non-compliant marketing practices — such as PDPA fines, CCCS penalties, or advertising standards sanctions — are not deductible.
Political or quasi-political advertising: Expenditure on political advertising or lobbying activities is not deductible under general tax principles.

The entertainment expense restriction catches many businesses off guard. Marketing teams that host client events, sponsor corporate hospitality, or provide gifts to business partners should work with their finance teams to ensure these expenses are correctly classified and that deductible exceptions are properly identified.

Capital vs Revenue Expenditure

The distinction between capital and revenue expenditure is the most significant issue in the tax treatment of marketing expenses. Revenue expenditure is deductible; capital expenditure generally is not (although capital allowances may be available for certain assets).

The general test is whether the expenditure creates a lasting asset or advantage (capital) or is incurred in the day-to-day operation of the business (revenue). For marketing expenses, this distinction is usually straightforward, but certain categories require careful analysis:

Website development: The cost of building a new laman web is typically treated as capital expenditure because it creates a lasting asset. However, ongoing website maintenance, updates, content additions, and hosting fees are revenue expenditure and deductible. If you redesign an existing website, the treatment depends on whether the redesign creates a fundamentally new asset (capital) or maintains and improves the existing one (revenue).
Brand development vs brand promotion: Developing a new brand identity — logo design, brand guidelines, trademark registration — for a new business may be capital. Ongoing promotional expenditure to maintain and build awareness of an existing brand is revenue.
Software and platforms: Purchasing marketing software outright is capital expenditure (potentially eligible for capital allowances under Section 19 or Section 19A of the Income Tax Act). Subscribing to software-as-a-service (SaaS) platforms on a monthly or annual basis is revenue expenditure and deductible.
Video and content assets: A corporate video with a long useful life may be treated as a capital asset. Short-form content created for specific campaigns and with a limited shelf life is more likely to be revenue expenditure.

When in doubt, the safest approach is to apply the “enduring benefit” test: if the expenditure provides a benefit that extends significantly beyond the current accounting period and creates a recognisable asset, it is likely capital. If the benefit is consumed in the current period as part of ongoing business operations, it is likely revenue.

Record-Keeping Requirements

IRAS requires businesses to maintain adequate records to support their tax deductions, including marketing expense claims. Under Section 67 of the Income Tax Act, records must be retained for at least five years from the relevant Year of Assessment.

For marketing expenses, the following records should be maintained:

Invoices and receipts: Original invoices from advertising platforms, agencies, freelancers, and suppliers. For digital advertising, download and retain monthly invoices from Google Ads, Meta Business Manager, and other platforms — auto-generated summaries are not sufficient.
Contracts and agreements: Agency retainer agreements, freelancer contracts, platform subscription agreements, and sponsorship contracts. These documents establish the nature and purpose of the expenditure.
Campaign documentation: Records showing the business purpose of each marketing campaign, including campaign briefs, objectives, and results. This documentation supports the “wholly and exclusively” requirement.
Payment records: Bank statements, payment confirmations, and credit card statements showing the actual payment of marketing expenses. Accrued but unpaid expenses may be deductible, but proof of the underlying obligation is required.
Entertainment records: For any entertainment expenses claimed as deductible exceptions, maintain detailed records including the date, venue, attendees, business purpose, and the amount spent. Without this documentation, the deduction will be disallowed.
GST documentation: If you are GST-registered, maintain proper tax invoices for marketing expenses to support input tax claims. Ensure that invoices from overseas suppliers — such as Google and Meta — comply with Singapore’s reverse charge provisions for imported services.

Modern accounting software and digital record-keeping systems make compliance straightforward. The key is to establish the record-keeping process at the start — retrofitting documentation at tax filing time is difficult and increases the risk of missing or incomplete records.

Common Marketing Tax Claims and Examples

To illustrate how the tax rules apply in practice, here are common marketing expense scenarios and their IRAS treatment:

Google Ads spending of SGD 5,000 per month: Fully deductible as revenue expenditure. Retain the monthly invoices from Google Ads and evidence that the campaigns were for business purposes. Annual deduction: SGD 60,000.
SEO agency retainer of SGD 3,000 per month: Fully deductible as revenue expenditure for ongoing SEO services. The agency contract and monthly reports serve as supporting documentation. Annual deduction: SGD 36,000.
New website development costing SGD 25,000: Capital expenditure — not immediately deductible as a revenue expense. However, the website may qualify for capital allowances under Section 19A of the Income Tax Act, allowing the cost to be written off over the useful life of the asset (typically three years for websites and software).
Corporate video production costing SGD 8,000: If the video is created for a specific short-term campaign, it is likely revenue expenditure. If it is a corporate brand video intended for long-term use, it may be capital. The distinction depends on the expected useful life and purpose.
Client dinner costing SGD 500: Not deductible under the entertainment expense restriction. However, if the dinner is part of a formal trade conference or exhibition open to the public, it may qualify for the trade exhibition exception.
Promotional merchandise (pens, notebooks) with company logo, SGD 2,000 total, each item under SGD 50: Deductible under the exception for promotional items bearing the company’s name, provided each item costs SGD 50 or less.
Influencer marketing campaign of SGD 10,000: Fully deductible as revenue expenditure for promotional services. Maintain the influencer agreement, content deliverables, and payment records.
Marketing automation subscription (HubSpot) of SGD 12,000 per year: Fully deductible as a revenue expense for SaaS subscription. Retain the subscription agreement and invoices.

Enhanced Deductions and Government Schemes

Beyond standard deductions, Singapore offers several government schemes that provide enhanced tax benefits for certain marketing-related activities. Taking advantage of these schemes can significantly amplify the tax benefit of your marketing investment.

Enterprise Development Grant (EDG): Enterprise Singapore offers the EDG, which can fund up to 50 per cent (or 70 per cent for qualifying SMEs) of qualifying project costs. Marketing-related projects that qualify include brand development, digital marketing strategy, and market expansion activities. The grant amount received is not taxable if used for approved purposes.
Market Readiness Assistance (MRA) Grant: The MRA grant supports Singapore SMEs in expanding overseas. It covers up to 50 per cent of eligible costs for overseas marketing activities, including market research, advertising, and trade fair participation in overseas markets. The maximum support is SGD 100,000 per new market per fiscal year.
Double Tax Deduction for Internationalisation (DTDi): Under Section 14K of the Income Tax Act, qualifying expenses incurred for overseas market expansion — including overseas advertising, trade fair participation, and market feasibility studies — may qualify for a 200 per cent tax deduction. The automatic DTDi scheme covers up to SGD 150,000 of qualifying expenses per Year of Assessment without prior approval.
Productivity Solutions Grant (PSG): The PSG supports the adoption of pre-approved digital marketing solutions, including CRM systems, marketing automation platforms, and e-commerce solutions. Qualifying businesses can receive up to 50 per cent support for the adoption cost.

These schemes are subject to eligibility criteria and may change. Businesses should check the current terms on the Enterprise Singapore and IRAS websites before applying.

Are Google Ads and Facebook Ads spending fully tax-deductible in Singapore?

Yes. Advertising spend on digital platforms — including Google Ads, Meta (Facebook and Instagram), LinkedIn, TikTok, and others — is fully deductible as revenue expenditure under Section 14(1) of the Income Tax Act, provided the advertising is for business purposes. The fact that the platform provider is based overseas does not affect the deductibility. However, GST-registered businesses should be aware of the reverse charge mechanism for imported digital services.

Can I claim a tax deduction for client entertainment expenses?

Generally, no. Section 17(1)(b) of the Income Tax Act disallows deductions for entertainment expenses. However, there are specific exceptions: entertainment provided to employees (excluding directors), entertainment at trade or industrial exhibitions open to the public, and promotional gifts bearing the company’s name or branding that cost SGD 50 or less per item. If your marketing activities involve client hospitality, structure them to fall within these exceptions where possible.

Is the cost of building a website tax-deductible?

Website development costs are typically treated as capital expenditure and are not immediately deductible as a revenue expense. However, the cost may qualify for capital allowances under Section 19A of the Income Tax Act, which allows the expenditure to be written off over the useful life of the website (commonly three years). Ongoing website maintenance, hosting, content updates, and minor enhancements are revenue expenditure and deductible in the year incurred.

How do I claim the Double Tax Deduction for overseas marketing?

The automatic DTDi scheme under Section 14K allows businesses to claim a 200 per cent deduction for qualifying overseas marketing expenses up to SGD 150,000 per Year of Assessment without prior IRAS approval. Qualifying expenses include overseas advertising, participation in overseas trade fairs and exhibitions, and overseas market feasibility studies. For expenses exceeding SGD 150,000, you must apply to Enterprise Singapore for approval before incurring the expenditure. Maintain detailed records of the overseas nature and business purpose of each expense.

Are marketing agency retainer fees deductible?

Yes. Monthly retainer fees paid to marketing agencies for ongoing services — including SEO, content marketing, social media management, Google Ads management, and general marketing strategy — are deductible as revenue expenditure. The retainer agreement should clearly describe the services provided, and invoices should be issued monthly or as agreed. One-off project fees are also deductible provided they relate to revenue-nature activities and not capital asset creation.

What happens if IRAS disallows a marketing expense deduction?

If IRAS disallows a deduction during an audit or review, the disallowed amount is added back to your taxable income, and you will owe additional tax plus interest. If the disallowance results from negligence or fraud, IRAS may impose penalties of up to 200 per cent of the tax undercharged. You have the right to object to the disallowance within 30 days of the notice of assessment and can appeal to the Board of Review and subsequently to the High Court. To minimise the risk of disallowance, maintain comprehensive records and seek professional tax advice for complex or unusual marketing expenditure.
