Can a publisher’s Open Access fee be charged to the grant that funded the research?
The NIH FAQ states: “Yes. The NIH will reimburse publication costs, including author fees, for grants and contracts on three conditions: (1) such costs incurred are actual, allowable, and reasonable to advance the objectives of the award; (2) costs are charged consistently regardless of the source of support; (3) all other applicable rules on allowability of costs are met.
