How can I empty my Apple Account balance?

If you cannot spend your balance, you can contact Apple directly and they will clear it:

Contact Apple for support and service - Apple Support

After that review this article for additional steps you may need to take if you are looking to change your region, such as:

• Cancel all subscription. When cancelling the subscription, it just prevents it from being renewed again, so if you do not want to wait until the expiration date, you will need to contact Apple to remove it immediately.
• If you want to use the App Store in your new region, make sure you have a payment method for that region. The region of the payment method must match the region of the device. That is how Apple is able to determine you are using the correct App Store.

Change your Apple Account country or region - Apple Support

Things to consider:

If you have any store credit on your Apple Account, then you will need to use it or ask for balance removal by ⇢ contacting Apple Support.

Important:

If you need to change your region, then click ▶︎ Change Region for step-by-step instructions. 🌐

Good luck! 👋🏼😉
