For the self-employed, these figures amounted to GHC 8.0 for native-bom workers and GHC 6.6 for the foreign-bom. In total, the gap between the average income tax per capita paid by a native- and foreign-bom worker amounted to GHC 29.2 (GHC 111.2 and 140.4, respectively). Of these 18.5%, 13.5% go to SSNIT (of which 2.5% are remitted to the National Health Insurance Authority), while the remaining 5% are allocated towards the mandatory Second Tier Occupational Scheme.
