Singapore Budget 2025: 100% CSA Deductions, Extended M&A Incentives, and Land Use Allowances Explained

The Singapore Budget 2025 introduced major tax measures to encourage innovation, cross-border business collaboration, and strategic land use. Among the most notable updates are the 100% tax deduction for qualifying cost-sharing agreements (CSA), the extension of Merger & Acquisition (M&A) incentives, and a more flexible Land Intensification Allowance (LIA). These changes are designed to support companies that invest in R&D, global expansion, and efficient use of land resources. In this post, we break down the key measures, who can benefit, and how to prepare for compliance.

Our analysis is based on the Verified budget announcements and expert reviews, including Baker McKenzie Insight and Grant Thornton Singapore.

📢 Key Updates for Businesses in 2025

1. What Are Cost-Sharing Agreements (CSA) and Why Do They Matter?

A Cost-Sharing Agreement (CSA) is a business arrangement where group companies share the costs of developing intellectual property (IP) or performing R&D activities. Traditionally, only part of these costs was deductible. With Budget 2025, Singapore now allows 100% tax deduction on qualifying CSA payments, provided they meet the arm’s length principle and are linked to income-generating activities.

• ✅ Covers cross-border arrangements with overseas affiliates
• ✅ Applies to payments for R&D, patents, software, and innovation projects
• ⚠️ Requires documentation to prove commercial benefit to the Singapore entity

Insight: This is a game-changer for multinationals with R&D hubs in Singapore, making it more attractive to allocate global innovation budgets locally.

2. How the 100% CSA Deduction Works in Practice

Let’s look at an example. A Singapore-based tech company contributes SGD 5 million annually to a global CSA for AI software development. Under previous rules, only partial deductions were allowed. With Budget 2025, the company can now deduct the entire SGD 5 million from taxable income, resulting in significant savings.

Case study: Tax consultants have noted that this measure aligns Singapore with other innovation hubs like Ireland, making it globally competitive.

3. 💡 Extension of Merger & Acquisition (M&A) Tax Incentives

Another key update is the extension of M&A tax allowances, which were previously set to expire. Eligible companies can continue to claim tax allowances on qualifying share acquisitions, encouraging corporate restructuring and expansion.

• 25% M&A allowance on the acquisition value, capped annually
• Stamp duty relief extended for qualifying transactions
• Focus on supporting SMEs pursuing consolidation for scale and efficiency

Question for readers: How will your company use these extended incentives — for local acquisitions or regional expansion?

4. Land Intensification Allowance (LIA) — What’s New?

The LIA was introduced to promote efficient land use for industrial purposes. Budget 2025 brings more flexibility by expanding the list of qualifying buildings and simplifying approval processes. Businesses in logistics, advanced manufacturing, and data centers stand to benefit.

1. Enhanced allowance rate for projects that incorporate green technology
2. Broader eligibility for high-value services sectors
3. Streamlined application to reduce waiting times

Experience: Industrial property consultants expect a surge in applications from data centers, which require high-density land usage combined with sustainable infrastructure.

5. International Comparisons and Why Singapore Stands Out

Many countries offer R&D credits or M&A reliefs, but Singapore’s combination of CSA deduction + M&A + LIA is unique. It creates a holistic ecosystem where companies can innovate, scale, and optimize land resources simultaneously.

6. Practical Steps for Businesses to Benefit

Companies should act now to maximize these incentives. Key action points include:

• Review all existing CSA arrangements and ensure documentation meets arm’s length standards.
• Identify potential M&A targets and align with incentive timelines.
• Work with property consultants to assess eligibility for expanded LIA.
• Engage tax advisors early to integrate these measures into financial planning.

Tip: Small and medium enterprises (SMEs) should not overlook these schemes — collective savings can significantly improve cash flow.

7. Summary and Key Takeaways

• 📌 100% tax deduction now applies to qualifying CSA payments under Budget 2025.
• 📌 M&A incentives are extended, supporting business consolidation and expansion.
• 📌 LIA scope is broadened, helping industries with land-intensive operations.
• 📌 Together, these measures strengthen Singapore’s position as an innovation and investment hub in Asia.
