Update: Please see the NIH Paylines & Resources page for the latest information.
The NIH Extramural Financial Operations Website covers NIH fiscal policy, award trend data, budget presentations, and information about the whole sausage-making process. If you scroll to the very bottom of the page, they now also provide a summary table with links to the funding policy of individual ICs. I’m still hopeful eventually these links will provide payline data. Most Advisory Councils have met now, so watch the Website of your favorite IC both for payline info and cleared concepts (ie, future funding opportunities). Best of luck to you all!
