**Tell us about your request**
The EFS CSI Controller helm-chart support supplying additional-resource-tags for access-points created by the controller:

https://github.com/kubernetes-sigs/aws-efs-csi-driver/blob/628019a/charts/aws-efs-csi-driver/values.yaml#L62

This setting should be made available in the add-on parameters for the aws-efs-csi-driver.

**Which service(s) is this request for?**
EKS

**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
What outcome are you trying to achieve, ultimately, and why is it hard/impossible to do right now? What is the impact of not having this problem solved? The more details you can provide, the better we'll be able to understand and solve the problem.

I would like to apply a consistent tagging policy to resources used by a deployment of my application, including resources created by Kubernetes controllers.

I would like to apply ABAC for IAM policies related to EFS (I haven't tested if there are other blockers here - ABAC support for EFS is documented as "partial").

Start with the linked aws-efs-csi-driver charts/aws-efs-csi-driver/values.yaml entry for additional-resource-tags, then trace how EKS add-on parameters are defined and passed through this roadmap request. Done means the add-on exposes this setting and forwards it to the EFS CSI controller so access points receive the requested tags.
