Initial development of the NICC was funded by the Annie E. Casey Foundation as part of the Low Income Working Families Project.
Funding to update the tool to use the tax and benefit rules that were in place in 2012 was provided by Urban Institute institutional funds. Other funding has been provided by the Department of Health and Human Services, Office of the Assistant Secretary for Planning and Evaluation (HHS/ASPE), and by the John D. and Catherine T. MacArthur Foundation.
NICC’s development built on an earlier tool, the Marriage Calculator, developed at the Urban Institute under contract with HHS Administration for Children and Families (ACF).
NICC’s calculations are performed by an adapted version of the TRIM3 microsimulation model. The standard version of TRIM3 is funded and copyrighted by HHS/ASPE and developed and maintained by the Urban Institute.
