This section describes how to develop budgets for S2S submissions. It explains how budgets map and additional special considerations. Please note that the Budgets Guide may also serve as helpful resource for budget development.

The SF424 can use either the R&R Budget form or the PHS 398 Modular Budget form. Modular Budget is only used by the NIH. If this is an NIH modular budget, it’s important to confirm the Budget Period and Project Dates of the funding proposal SmartForm and that yes is selected for the Modular Budget Question. This will ensure your Total Direct Costs, Total Indirect Costs, and Total Project costs are calculated correctly using the modular method. It is also important to note that budget periods and their dates are also determined on the Budget Periods and Key Dates page. This page will be used in accordance with the budget information below when the SF424 budget is created.
