Malaysia's tax architecture faces renewed scrutiny as policymakers weigh options for a more balanced consumption tax regime. An economist from IPPFA Sdn Bhd has thrown support behind a hybrid sales and service tax (SST) model, arguing that the addition of input tax credit mechanisms would address longstanding inefficiencies in how taxes accumulate through the supply chain.
Mohd Sedek Jantan, the firm's director of investment strategy and country economist, contends that both existing alternatives present structural problems. The current SST, he argues, casts too narrow a net to generate the revenue needed for government operations while simultaneously creating cascading tax effects that distort pricing. Conversely, the goods and services tax (GST) casts its net too wide, imposing excessive compliance burdens across the economy. A reformed hybrid approach that selectively incorporates elements from each model would offer Malaysia a more pragmatic solution tailored to local economic conditions.
The core of Jantan's proposal centres on integrating an input tax credit system into an enhanced SST framework. This mechanism would fundamentally alter how businesses account for taxes paid at earlier stages of production and distribution. Rather than treating such taxes as an irrecoverable cost component, companies could offset taxes already paid against their own tax liabilities, creating a cleaner flow of tax obligations through the supply chain.
To illustrate how this works in practice, consider a typical manufacturing and wholesale transaction. A manufacturer producing goods valued at RM100 applies RM10 in tax, meaning the wholesaler purchases the items for RM110. When the wholesaler subsequently marks up those goods to RM130 and collects RM13 in tax, an input credit system permits the wholesaler to deduct the initial RM10 tax already paid from the RM13 they have collected. The net remittance to the government becomes only RM3—the difference between what they collected and what they already paid upstream.
Jantan emphasises that while this mechanism does not automatically translate into lower consumer prices, it meaningfully reduces cost pressures on businesses handling goods in intermediate stages of the supply chain. By preventing taxes from embedding themselves as permanent cost components at each transaction point, businesses face less pressure to inflate their selling prices simply to maintain profit margins. The psychological and operational impact of this relief matters significantly for Malaysia's competitive positioning in regional trade and investment contexts.
Without input tax credits, the economist warns, Malaysia faces what economists call tax cascading—a compounding effect where taxes imposed at one stage become incorporated into the cost base upon which the next business calculates its own tax liability. The result is a form of involuntary double or multiple taxation, where the same underlying value gets taxed repeatedly as goods move through the distribution network. This distortion particularly harms Malaysian manufacturers competing internationally, as they face embedded costs that their counterparts in countries with proper input credit systems do not carry.
The timing of this proposal aligns with broader government interest in tax reform. Last week, Prime Minister Datuk Seri Anwar Ibrahim publicly signalled that the government is actively exploring structural changes to make Malaysia's taxation system more progressive while remaining competitive. He specifically mentioned consideration of incorporating selected elements from the GST model into the existing SST framework—a clear indication that policymakers are receptive to hybrid approaches rather than wholesale replacement of the current regime.
Malaysia's recent tax history provides important context for this debate. The country previously operated under a GST system that drew significant criticism from small and medium-sized enterprises citing compliance costs and implementation complexity. The reversion to SST in 2018 reflected political commitments to simplify the system for businesses, particularly smaller operators. However, SST's narrower revenue base has created fiscal pressures and left unresolved the cascading tax problem that penalises manufacturing and export sectors.
From a regional perspective, Malaysia's tax policy choices matter beyond its borders. As part of the ASEAN community and a significant player in global supply chains, Malaysia's tax efficiency directly affects competitiveness relative to competitors like Vietnam, Thailand, and Indonesia. Countries operating proper input tax credit systems create advantages for their manufacturers that cascade through regional value chains. A reform that enhances Malaysia's competitive position without requiring wholesale system overhaul would be strategically valuable.
Implementing input tax credits would require substantial administrative enhancements to Malaysia's tax authority infrastructure. The system demands sophisticated tracking of tax flows through supply chains and reliable verification that credits claimed correspond to actual taxes paid at earlier stages. This represents a meaningful investment in tax administration capacity, though considerably less disruptive than transitioning to an entirely new tax regime.
The proposal also carries implications for different business sectors. Retail and service businesses would experience different impacts than manufacturing and wholesale operations, necessitating careful calibration during design phases. Policymakers must balance the benefits of reduced cascading against potential revenue effects and ensure the system remains transparent for small businesses without creating excessive compliance complexity.
Economist Jantan's endorsement of the hybrid model with input credits contributes important technical analysis to an ongoing policy conversation. His framework explains how Malaysia could capture GST's advantages in preventing tax cascading while maintaining the administrative simplicity and political acceptability that SST provides. As the government continues refining its tax reform agenda, this analytical perspective highlights a potentially viable middle path forward for Malaysia's consumption tax system.
