Malaysia's tax architecture is under scrutiny as economists weigh the merits of reforming the current system to balance revenue generation with economic efficiency. An investment strategist at IPPFA Sdn Bhd has thrown his weight behind a hybrid approach to the nation's sales and service tax, arguing that the inclusion of input tax credits could significantly ameliorate the structural problems inherent in the existing framework.
The present SST regime, according to Mohd Sedek Jantan, operates within an overly narrow scope that proves insufficient for generating the revenue needed to sustain government operations while simultaneously failing to adequately address the problem of tax cascading through the supply chain. Conversely, the broad-based goods and services tax model, which the government abandoned in 2018 following public backlash over perceived regressive impacts, casts too wide a net. A middle-ground hybrid system, in his assessment, represents the optimal policy position for Malaysia's current economic circumstances.
The cornerstone of Mohd Sedek's proposal centres on incorporating input tax credits into the hybrid SST structure. This mechanism operates on a fundamentally different principle than the current system, allowing businesses at each stage of production and distribution to recover taxes paid on inputs used in generating their own taxable outputs. The practical effect, he explained, is that tax liability becomes attached only to the genuine value added at each transaction point rather than accumulating as a hidden cost component passed downstream.
To illustrate how this mechanism would function in practice, Mohd Sedek outlined a straightforward supply-chain scenario. When a manufacturer sells goods valued at RM100 to a wholesaler, with RM10 in tax applied, the wholesaler's acquisition cost rises to RM110. Should that wholesaler subsequently sell the same goods for RM130, generating RM13 in tax revenue, the input credit system permits offsetting the previously paid RM10 against the RM13 now collected, reducing net remittance to just RM3.
This structured approach addresses a critical economic distortion that plagues pure cascading tax systems. Without input credits, taxes imposed at earlier supply-chain stages become embedded in business costs, which companies then use as the foundation for calculating their own prices at subsequent stages. The outcome is a self-perpetuating spiral whereby taxation drives up costs, which drive up prices, which become subject to further taxation—a vicious cycle that artificially inflates consumer prices beyond what genuine economic value would justify.
The economist emphasised that while input tax credits do not guarantee lower end-consumer prices, they perform the essential function of preventing the accumulation of tax burden across production and distribution networks. By ensuring businesses do not remit tax on tax, the mechanism preserves price competitiveness and reduces hidden levy costs embedded in final goods and services. This distinction carries particular significance for export-oriented sectors, where embedded tax costs reduce international competitiveness, and for import-competing industries attempting to maintain domestic market share.
The timing of this economist's intervention aligns with recent signals from Malaysia's political leadership regarding tax system reform. Prime Minister Datuk Seri Anwar Ibrahim, speaking last Tuesday, indicated that the government is actively exploring pathways toward a more progressive taxation structure. His statement specifically referenced the possibility of selectively incorporating elements from the GST framework into the existing SST architecture, suggesting openness to hybrid models that might capture the revenue-raising benefits of broader-based taxation while avoiding the political liabilities that led to the previous GST's reversal.
For Malaysian policymakers, the input tax credit proposal addresses several pressing economic considerations simultaneously. The nation faces persistent pressures on government revenues amid demographic shifts, infrastructure requirements, and social spending expectations. Simultaneously, Malaysian businesses operate in an increasingly competitive regional environment where production costs significantly influence export performance and attractiveness to foreign investors. A hybrid SST with input credits could theoretically enhance the fiscal position while reducing structural cost burdens on the productive sector.
The broader implications for Malaysia's economy warrant careful consideration. Small and medium enterprises, which constitute the backbone of employment and economic dynamism, often lack the sophistication to navigate complex tax compliance frameworks. A well-designed input credit system, accompanied by proportionate administrative procedures, could actually simplify compliance while reducing the effective tax burden. Conversely, poorly implemented mechanisms could impose disproportionate compliance costs on smaller operators who lack dedicated tax departments.
Regionally, Malaysia's tax system reform carries weight beyond domestic policy circles. Other Southeast Asian economies, particularly those in the ASEAN Economic Community framework, maintain varying approaches to value-added and consumption taxation. A successful hybrid model could provide a template for regional peers while positioning Malaysia as a thought leader in progressive tax design. Conversely, reform missteps could impose competitive disadvantages relative to lower-tax jurisdictions competing for manufacturing relocation and foreign direct investment.
The political dimension cannot be overlooked. The previous GST experiment, introduced in 2015 and repealed in 2018, remains a sensitive topic in Malaysian political discourse. Public perception of consumption tax measures continues to shape electoral calculations, making the hybrid approach appealing to policymakers seeking revenue enhancement without revisiting policies associated with the preceding administration. However, the success of any new system will ultimately depend on transparent communication regarding both its mechanisms and its rationale.
As the government proceeds with exploring reform options, technical economists like Mohd Sedek Jantan serve a critical function in articulating how specific design features address known economic problems. The input tax credit mechanism, grounded in international best practice and supported by economic theory, represents an evidence-based approach to tax system improvement. Whether Malaysia's policymakers will embrace these recommendations remains to be seen, but the emerging policy conversation suggests receptiveness to genuine structural reform.
