This paper is a thematic review of the existing literature on International Public Sector Accounting Standards (IPSAS) between 2000 and 2023. The review finds various advantages associated with the high adoption rates in the literature in the developed world. It also identified challenges associated with implementation and the effects of the cash-basis standard in developing countries. The study finds that uniform application may not be feasible at this stage of the diffusion process given the inherent limitations in developing countries. This review also provides a platform for identifying strands of the literature which have been underexplored and require further studies.
