Cost share

Learn about cost sharing, the commitments and documentation required

Definition of cost share

Cost sharing means charging part of the costs of a sponsored project to a source other than the sponsor. If cost-sharing is offered in any part of the proposal, it is a binding commitment that must be met and documented.

Ohio State and the College of Public Health discourage voluntary cost share unless the funding opportunity announcement (FOA) has language suggesting that the cost share may influence the proposal review. Note: cost share is a real expense and the source for the expense must be identified in advance. The PI’s division chair, ADR, and assistant dean for finance and administration must review and approve any proposal with a cost share before its submission to the funder. If prior approval is not secured, the award is unlikely to be accepted. 

Types of cost share: Required and voluntary

Sources of cost share

Allowable and unallowable types of cost share

Requesting, approving and documenting cost share 

If the FOA refers to cost share, the director of research support or grants manager provides guidance to the PI regarding whether the specific cost share is required or voluntary, the process of securing the required approvals, and drafting a budget that includes the cost share. Typically, investigators in CPH and other units, possibly including external collaborators, are expected to assist in meeting the cost share expectations in the FOA. The PI may ask the grants manager for assistance in drafting the email request for approval from CPH. The email request, which should specify the FOA and include the draft budget, is sent to the division chair, ADR, and assistant dean for finance and administration for approval.

If approved, the assistant dean for finance and administration emails documentation of the approval, which is to be included in the proposal and attached to the ePA005 together with the approved budget. The cost share must be documented on the ePA005 in the cost share section by checking the source(s) of the cost share and listing the amount(s).

Expensing cost share commitments in Ohio State's financial system 

If any cost sharing is included in a proposal (required or voluntary, in-kind, cash, or third party), the promised cost share becomes a requirement of the award whether or not that requirement is specified in the award document. All cost sharing must be documented as having been provided by the end of the project period. It is best to expend cost share commitments in real time with the project in the same manner as expenses to the sponsor. The grants manager can provide guidance to the PI to ensure cost share expenditures are reflected in the project financials and that all cost share contractual obligations are met.
