## Update Existing Subscriptions

When you integrate with Stripe Tax, you need to update your existing subscriptions to ensure that tax is automatically calculated going forward. Stripe provides tooling to help you with this process, or you can choose to manually update subscriptions if you require more control over specific options.

### Using Automated Tooling

Before you begin, ensure that Stripe Tax is activated. Refer to the [setup guide](https://stripe.com/docs/tax/set-up) for instructions.

To update your existing subscriptions using the automated tooling:

1.  Navigate to the **Dashboard**.
2.  Review the subscriptions that require updating.
3.  Examine the recommended actions presented by Stripe.
4.  Make any necessary manual adjustments.

Stripe will then remove manual tax rates from your subscriptions. This process can take up to 5 business days. You will receive an email notification upon completion.

**Note:** Tax changes are not prorated. The updates will take effect at the beginning of the next billing cycle.

You can use the automated tooling to update subscriptions that meet the following criteria:

*   Are currently active.
*   Do not automatically collect tax.
*   Have sufficient address information for tax calculation.
*   Have the `tax_behavior` set on the price.

The following types of subscriptions require updating:

*   Subscriptions with schedules. For more details, refer to [Update subscriptions with schedules](https://stripe.com/docs/billing/subscriptions/subscription-schedules#update-subscriptions).
