Low-skilled immigrants indirectly affect public finances through their effect on native wages & labor supply. We operationalize this indirect fiscal effect in various models of immigration and the labor market. We derive closed-form expressions for this effect in terms of estimable statistics. Empirical quantifications for the U.S. reveal that the indirect fiscal benefit of one low-skilled immigrant lies between $770 and $2,100 annually. The indirect fiscal benefit may outweigh the negative direct fiscal effect that has previously been documented. This challenges the perception of low-skilled immigration as a fiscal burden.
