# Accounts v2 now always returns the responsibilities field when the defaults field is included

## What’s new

The [defaults.responsibilities](https://docs.stripe.com/api/v2/core/accounts/retrieve.md?api-version=2025-12-15.preview#v2_retrieve_accounts-response-defaults-responsibilities) field is now always returned in the [Accounts v2](https://docs.stripe.com/api/v2/accounts.md?api-version=2025-12-15.preview) object if you specify [defaults](https://docs.stripe.com/api/v2/core/accounts/retrieve.md?api-version=2025-12-15.preview#v2_retrieve_accounts-response-defaults) in the [include](https://docs.stripe.com/api-includable-response-values.md?api-version=2025-12-15.preview) field. This is a breaking change for users on the existing public preview for Accounts v2, which became available in our GA channel as of [2025-12-15.clover](https://docs.stripe.com/changelog.md#2025-12-15.clover).

## Why is this a breaking change?

The `defaults.responsibilities` field is returned even when [responsibilities.fees_collector](https://docs.stripe.com/api/v2/core/accounts/retrieve.md?api-version=2025-12-15.preview#v2_retrieve_accounts-response-defaults-responsibilities-fees_collector) and [responsibilities.losses_collector](https://docs.stripe.com/api/v2/core/accounts/retrieve.md?api-version=2025-12-15.preview#v2_retrieve_accounts-response-defaults-responsibilities-losses_collector) are `null`. If your existing integration doesn’t expect this field in API responses, you must use the new object structure to prevent validation errors.

## Impact

Previously, the [responsibilities.requirements_collector](https://docs.stripe.com/api/v2/core/accounts/retrieve.md?api-version=2025-12-15.preview#v2_retrieve_accounts-response-defaults-responsibilities-requirements_collector) field wasn’t returned unless `fees_collector` and `losses_collector` were present in the response.

You must update your integration to expect the `defaults.responsibilities` field, even if you didn’t set `fees_collector` and `losses_collector` when [creating](https://docs.stripe.com/api/v2/core/accounts/create.md?api-version=2025-12-15.preview) or [updating](https://docs.stripe.com/api/v2/core/accounts/update.md?api-version=2025-12-15.preview) the account. Make sure your integration correctly handles `fees_collector` and `losses_collector` when their values are `null`.
