This study used a quantitative approach and a case study design was used as the research design. A simple random sampling method was used in this research to guarantee fair representation and widespread results for the general population. Primary data for this research was collected using a questionnaire involving taxpayers. Data analysis was done using inferential statistics for the statistical data with the aid of SPSS version 26. Data was analyzed and presented in tables and figures. The study revealed that technological factors, organizational factors, and support factors, have a positive relationship with GITS Performance. The model constructed in this study showed that Technological Factors, Organizational Factors, and Support Factors, (TOS) account for 94.6% of the GITS Performance. Therefore, TOS (Technological Factors, Organizational Factors, and Support Factors) might be employed to make better use of the GITSs that have been put in place to increase revenue collection by Tanzanian local government authorities. Future studies should take into account all other kinds of own sources of revenue that are gathered utilizing the GITS as this research only looked at the business license as the primary OSR to analyze factors affecting the GITS performance. To facilitate effective data collection, storage, sharing, regular data updates, and system integration among LGA systems and other stakeholders, the study advises LGAs to develop, introduce, operationalize, and update policies, rules, and procedures that govern GITS's applications in revenue collection. Keywords: GITS Performance, Technological, Organizational, Support Factors 1. Introduction Local governments have greater autonomy and are more attentive to the needs and objectives of their residents when they have robust local revenue-collecting systems. Tanzanian local governments have decided to invest in information technology to boost tax collection. This is so that local government performance and the standard of public service delivery may be improved by using information technology (Dwivedi et al., 2015; Arpaci, Yardimci, Ozkan, & Turetken, 2012; Mandal & Gunasekaran, Paper Id: 230049 https://doi.org/10.37082/IJIRMPS.v11.i2.230049 1
