AWS Cost Allocation Tags Support for Account Tags

AWS has introduced support for Cost Allocation tags across AWS Cost Management products, allowing customers with multiple member accounts to use their existing AWS Organizations account tags directly in cost management tools. Account tags are applied at the account level in AWS Organizations and automatically apply to all metered usage within tagged accounts, eliminating the need for manual configuration and maintenance of separate account groupings in AWS Cost Explorer, Cost and Usage Reports, AWS Budgets, and Cost Categories.

Key Benefits

  • Analyze costs by account tag directly in Cost Explorer and Cost and Usage Reports (CUR 2.0 and FOCUS).
  • Set up AWS Budgets and AWS Cost Anomaly Detection alerts on groups of accounts without configuring lists of account IDs.
  • Build complex cost categories on top of account tags for further categorization.
  • Enable cost allocation for untaggable resources including refunds, credits, and certain service charges.
  • Automatically apply changes when new accounts join or existing accounts are removed.

What to do

  • Apply tags to accounts in the AWS Organizations console.
  • Activate those account tags from the Cost Allocation Tags page in the Billing and Cost Management console.

This feature is generally available in all AWS Regions, excluding GovCloud (US) Regions and China (Beijing) and China (Ningxia) Regions.
