Factors affecting individual income tax compliance in Thu Dau Mot City: An approach from the Theory of Planned Behavior (TPB) and the Fischer Tax Compliance Model

2025-12-18T13:17:08+07:00

This study analyzes factors influencing personal income tax (PIT) compliance in Thu Dau Mot city, Binh Duong province, drawing on theoretical foundations including the Theory of Planned Behavior (TPB), the Fischer Tax Compliance Model, Transaction Cost Theory (TCT), and Rational Choice Theory (RCT). Employing a mixed-methods approach, the research identifies six determinants affecting tax compliance behavior: tax knowledge, perceived tax fairness, tax rates, penalty severity, quality of tax services, and compliance costs. Among these, tax knowledge and tax service quality show the strongest positive effects, whereas tax rates and compliance costs exert negative influences. Proposed solutions include enhancing tax education and outreach, simplifying administrative procedures, improving tax service quality, and developing a transparent and equitable tax system to foster voluntary
compliance.

2025-12-19T09:26:42+07:00

In the era of digital transformation, small and medium-sized enterprises (SMEs)
in Vietnam, particularly accounting enterprises located in Vinh Tan Ward, Ho Chi Minh
City, are facing both opportunities and challenges in integrating digital technologies and
artificial intelligence (AI) to achieve sustainable development. This study investigates the
interrelationships among Digital Conversion (DC), Digital Technology (DT), Artificial
Intelligence (AI), and Sustainable Development (SD) in the context of accounting SMEs.
Grounded in the Resource-Based View (RBV) and the Technology–Organization
Environment (TOE) framework, the research model proposes five hypotheses linking DC,
DT, AI, and SD. Data were collected through a structured survey using a five-point Likert
scale, capturing managerial and employee perceptions regarding digital practices and
sustainability. Statistical analysis was conducted using SPSS software, including reliability
testing, correlation, and regression analysis, to examine causal relationships among the
variables. The findings are expected to highlight the central role of DC in driving the adoption of digital technologies and AI, which in turn promote sustainable development
within SMEs. The study contributes theoretically by extending the understanding of the
digital transformation–sustainability nexus in the accounting sector, while also offering
practical implications for managers in formulating digital strategies aligned with
