Malaysia's tax system may be heading towards a more nuanced approach that blends elements of existing frameworks. An economist from IPPFA Sdn Bhd has voiced support for a hybrid sales and service tax (SST) system that would incorporate input tax credit mechanisms, addressing longstanding concerns about how taxes accumulate through production and distribution networks.

Mohd Sedek Jantan, the investment strategy director and country economist at IPPFA Sdn Bhd, argues that neither the current SST nor a full goods and services tax (GST) system represents an optimal solution for Malaysia's fiscal needs. The existing SST framework, he contends, operates too narrowly in scope to generate the revenue levels required for government operations while simultaneously failing to prevent tax cascading—the problematic phenomenon where taxes compound as goods move through supply chains. Conversely, a comprehensive GST regime casts too wide a net, potentially creating unintended economic consequences across sectors.

The economist's endorsement of a hybrid model reflects growing recognition among fiscal policy analysts that Malaysia requires a tax structure tailored to its specific economic context. Rather than adopting wholesale either the narrow SST or expansive GST approaches, the hybrid framework would selectively incorporate elements from GST while maintaining the operational structure of SST. This middle-ground approach appeals to policymakers concerned about revenue adequacy, business competitiveness, and social equity simultaneously.

Central to Jantan's advocacy is the inclusion of an input tax credit mechanism within any reformed SST architecture. This mechanism functions by allowing businesses to offset taxes paid on inputs against taxes collected on outputs, thereby preventing the accumulation of tax burdens as products traverse through manufacturing, wholesale, and retail stages. The distinction may seem technical, but its practical implications are substantial for Malaysia's business environment and ultimately consumer prices.

Jantan illustrated the mechanism's operation through a concrete example spanning the supply chain. When a manufacturer sells goods to a wholesaler for RM100 and levies RM10 in tax, the wholesaler's immediate cost is RM110. Subsequently, the wholesaler sells these goods for RM130 and collects RM13 in tax. Under an input tax credit system, the wholesaler can deduct the RM10 previously paid from the RM13 collected, remitting only the net difference of RM3 to government. This approach ensures that tax functions purely as a final consumption tax rather than embedding itself as an intermediate cost at each supply chain stage.

Without such a credit mechanism, the economist warned, taxes imposed earlier in production chains become part of the cost base that subsequent businesses use to calculate their own selling prices. This creates a pernicious cycle: tax is imposed, becomes embedded in costs, forces price increases, and then tax is imposed again on the higher price. The result is exponential growth in effective tax rates as products move towards consumers, distorting price signals and creating artificial cost inflation unrelated to underlying economic value.

The practical distinction matters considerably for Malaysia's manufacturing sector and small-to-medium enterprises, which operate on relatively thin margins and depend heavily on regional supply chains. Tax cascading effectively penalizes businesses further down the supply chain and can make Malaysian products less competitive internationally when compared to countries operating under credit-based systems. For consumers, cascading effects manifest as unexplained price premiums that reflect cumulative tax burdens rather than genuine production costs.

Jantan's comments arrive as Malaysian policymakers deliberate tax system reforms at the highest levels. Prime Minister Datuk Seri Anwar Ibrahim signalled last week that the government is actively examining mechanisms to make Malaysia's tax system more progressive while incorporating selective GST elements into the existing SST framework. This signals serious governmental consideration of the hybrid approach that economists like Jantan have advocated, moving beyond rhetorical commitment towards substantive policy exploration.

The timing of this debate reflects Malaysia's broader challenge: generating sufficient government revenue to fund public services and infrastructure while maintaining business competitiveness and protecting household purchasing power. Many Southeast Asian economies have grappled with similar tensions, with countries like Thailand and Indonesia experimenting with various VAT and GST configurations to balance these competing objectives. Malaysia's policymakers can draw instructive lessons from regional experiences while designing a system suited to the nation's particular fiscal and economic circumstances.

Implementing an input tax credit system would require sophisticated tax administration infrastructure capable of tracking credits across complex supply chains and preventing fraudulent claims. The Inland Revenue Board would need enhanced compliance monitoring and information systems to manage the increased administrative complexity compared to the current SST arrangement. Training for tax professionals and businesses would also prove essential to ensure proper implementation and voluntary compliance with new procedures.

The economist's emphasis on incorporating input tax credits rather than merely adjusting tax rates underscores an important principle: tax system design fundamentally shapes business behaviour and price formation across economies. A well-designed hybrid framework with proper credit mechanisms could preserve government revenue objectives while reducing unintended economic distortions. Conversely, merely borrowing GST revenue potential without implementing its supporting mechanisms could replicate GST's broader scope while losing the efficiency gains that input tax credits provide.

As Malaysia moves forward with tax reform discussions, the role of expert voices like Jantan's will prove increasingly important. The economist's focus on input tax credit mechanisms addresses a specific technical flaw in the current system rather than advocating for ideological positions around taxation philosophy. This grounding in practical mechanics rather than abstract principles may resonate with policymakers seeking solutions that improve system efficiency without requiring revolutionary institutional restructuring.
