Person – Job Fit and Job satisfaction are two integral parts associated with every job. While the first is constructed by amalgamation of the ability to perform the job and availability of the resources, the second one measures the mental status of the workers while they are in the job. Several research works have been conducted to estimate the interrelationship among these two aspects associated with jobs.This study set out to clarify how Person–Job Fit and Job Satisfaction are structured and how they interact in shaping employees’ experiences within the Central Board of Indirect Taxes and Customs. Using CFA and SEM, the analysis demonstrated that P–J Fit is best understood as a higher-order construct comprising two distinct yet related dimensions—Demand–Ability Fit and Need–Supply Fit—while Job Satisfaction is effectively captured as a second-order construct reflected in nine classic facets. The structural model revealed a strong and positive path from P–J Fit to Job Satisfaction, with P–J Fit explaining more than half of the variance in overall satisfaction. An alternative first-order model further showed that both D–A Fit and N–S Fit significantly predict Job Satisfaction, with N–S Fit exerting a somewhat stronger influence.
