## Eligibility & scope

Allows Swiss applicants to include co-applicants in Denmark, Norway, Sweden, the Netherlands (up to 50% of budget), or the UK for humanities/social sciences projects (up to 30% of budget, co-funded with ESRC/AHRC).

## Summary

The SNSF International Co-Investigator Scheme lets Swiss-based researchers add co-applicants from Denmark, Norway, Sweden or the Netherlands to their project budget, or from the UK for humanities and social sciences projects co-funded with ESRC/AHRC. It works as an add-on to a standard SNSF application rather than a separate joint call, with a single SNSF evaluation and cut-offs twice a year. Partner countries are capped by budget share: up to 50% for the Nordic/Dutch partners and up to 30% for UK humanities/social sciences co-applicants.

## Who should apply

- Researchers eligible to apply to SNSF as the lead applicant based in Switzerland
- Projects including a co-applicant at a partner institution in Denmark, Norway, Sweden or the Netherlands
- Humanities or social sciences projects with a UK-based co-applicant co-funded by ESRC/AHRC
- Teams able to work within the fixed budget share caps per partner country

## Key dates

- Cut-off deadlines twice yearly: 1 April and 1 October
- Continuous call frequency with single-stage application
- Single evaluation conducted by SNSF

## Tips for applicants

- Budget share caps are fixed (50% for Nordic/Dutch partners, 30% for UK humanities/social sciences), structure the co-applicant's work package to fit within this limit before submission.
- There is no separate joint budget pot, so the entire project must be costed and justified within the standard SNSF application.
- Check country-specific employment rules early if hiring staff abroad, since these vary by partner country and can affect timeline.
