Small and Medium Enterprises constitute the backbone of Pakistan’s economy and play a central role in economic growth, employment generation, innovation, and regional development. Despite their importance, a large proportion of these enterprises operate informally, making tax evasion a persistent structural problem. This thesis examines the economic impact of tax evasion by SMEs in Pakistan, focusing on its implications for fiscal stability, economic growth, public welfare, and long-term development planning. The study explores the scale of tax evasion within the SME sector, investigates its underlying causes, and evaluates its broader macroeconomic consequences, while proposing policy-oriented solutions aimed at improving compliance.The research adopts a quantitative analytical framework supported by simulated macroeconomic and sectoral data aligned with indicators published by national and international institutions. Established economic theories and models are applied, including the Allingham–Sandmo model of taxpayer behavior, Keynesian fiscal multiplier analysis, regression-based econometric estimation, and sensitivity analysis. These approaches are complemented by micro-level case illustrations from retail and manufacturing SMEs, enabling the study to link individual firm behavior with aggregate economic outcomes and enhance analytical robustness.The findings indicate that tax evasion among SMEs in Pakistan remains widespread and systematic, significantly weakening public revenue mobilization. Econometric results demonstrate a clear negative relationship between SME tax evasion and economic growth, alongside a positive association with fiscal deficits. Higher levels of tax evasion are shown to reduce the government’s capacity to finance essential public goods, particularly in education, health, and infrastructure, thereby constraining social welfare and inclusive development. Multiplier simulations further suggest that improvements in tax compliance could generate substantial gains in national output by strengthening aggregate demand and public investment capacity.The study identifies several interrelated drivers of tax evasion within the SME sector. These include the complexity of tax regulations, high compliance costs, weak enforcement mechanisms, institutional corruption, limited financial literacy, and a deep-rooted lack of trust between businesses and tax authorities. These factors incentivize informality and create an uneven competitive environment in which compliant firms are disadvantaged. Moreover, operating outside the formal tax system restricts SMEs’ access to credit, technology, and growth opportunities, reinforcing low productivity and economic inefficiency.From a social perspective, the research highlights that tax evasion indirectly affects employment and income distribution through reduced public spending and slower economic expansion. Improved compliance is shown to have the potential to support job creation, reduce poverty, and strengthen welfare outcomes by enabling greater investment in labor-intensive public services and infrastructure. These findings emphasize that SME tax evasion is not merely a fiscal issue but a broader development challenge with long-term economic and social consequences. This thesis contributes to existing literature by providing an integrated micro–macro analysis of SME tax evasion in Pakistan, addressing empirical gaps and contextualizing the issue within the country’s institutional and regulatory environment. The study offers practical policy recommendations centered on tax simplification, digitalization of tax administration, reduction of compliance costs, enhanced transparency, and trust-building measures between SMEs and tax authorities. By reframing SMEs as potential drivers of sustainable growth rather than sources of fiscal risk, the research provides evidence-based insights to support more effective taxation policy, improved governance, and inclusive econo
