What happens when I go Over My iCloud Storage Limit?

iCloud offers 5GB of free storage space to all its users. If you exceed your iCloud 5GB storage limit, then photos and videos will not upload to your iCloud account and your library will not stay up to date across your devices. So you need to upgrade your storage plan or reduce the amount of storage which you are using. You can upgrade your iCloud storage from your iPhone, iPad, Mac or Windows PC. iCloud offers 50GB space for $0.99/month, 200GB space for $2.99/month or 1TB space for $9.99/month.

If you want to reduce the storage for iCloud Photo Library, then delete the photos and videos that you don't want to keep from your iOS device. You can also delete your photos and videos on iCloud.com. Once you delete the photos nd videos from iCloud, they will immediately remove from your device and won't be available for recovery in your "Recently Deleted" album.
