AWS Billing and Cost Management
User Guide (Version 2.0)

User-Defined Cost Allocation Tags

User-defined tags are tags that you define, create, and apply to resources. After you have created and applied them, you can activate them on the Billing and Cost Management console for cost allocation tracking. After you activate them, they appear on your cost allocation report. You can then use the tags on your cost allocation report to track your AWS costs.

Applying User-Defined Cost Allocation Tags

For ease of use and best results, use the AWS Tag Editor to create and apply user-defined tags. The Tag Editor provides a central, unified way to create and manage your user-defined tags. For more information, see Working with Tag Editor in Getting Started with the AWS Management Console.

For supported services, you can also apply tags to resources using the API or the AWS Management Console. Each AWS service has its own implementation of tags. You can work with these implementations individually, or use Tag Editor to simplify the process. The following is a current list of services that support tags:

After you create and apply user-defined tags, you can activate them for cost allocation. If you activate your tags for cost allocation, it's a good idea to devise a set of tag keys that represent how you want to organize your costs. Your cost allocation report displays the tag keys as additional columns with the applicable values for each row, so it's easier to track your costs if you use a consistent set of tag keys.


User-defined cost allocation tags created by linked accounts can take up to seven days to appear in the Billing and Cost Management console. To speed the process up, you can trigger a manual refresh to make them appear within 24 hours.

Some services launch other AWS resources that the service uses, such as Amazon EMR or AWS Marketplace launching an EC2 instance. If the supporting service (EC2) supports tagging, you can tag the supporting resources (such as the associated Amazon EC2 instance) for your report. For a full list of taggable resources, use the Tag Editor to search for taggable resources. For more information about how to search for resources using Tag Editor, see Searching for Resources to Tag.
