# Annual-only plans for Clerk Billing

Clerk Billing now has support for annual-only subscriptions. Previously, all plans renewed monthly with an option to subscribe on an annual basis. Now, you can configure plans to support annual-only billing.

To enable support for annual-only plans, visit your applications [Updates](https://dashboard.clerk.com/~/updates) page to opt-in to annual-only plans.

> Opting into annual-only plans will result in the `fee` property of plans potentially being `null`. Please ensure any logic your application has that interacts with the `fee` property is updated to account for `null` values.

To configure a plan for annual-only billing, enable only the "Annual base fee" option in the plan settings.
