Can a game pass be purchased from an account balance of a child account?

Hello, first it's a pleasure to be able to help you today.

Hello JV, unfortunately not,, If you are trying to buy a subscription only with balance, I regret to inform you that this is not possible, the new Xbox policies are necessary to back up the purchase with a credit card or debit and this is mandatory, even for a child account or not.

I am sorry for the inconveniences that this may cause you.

So account balance cannot be used to purchase game pass? Only credit/debit cards?

Yes, account balance can be used to purchase game pass, i just purchased it today part of it was paid with a partial balance i had on my microsoft account and the rest was paid with my paypal account.

This is an issue with the market place and 360 games.

This can be an issue with a child account or trying to use Microsoft credits, some purchases may need to be created on the Xbox 360

Hello Laura, this message appears because your child's account is a child and it is not enable for purchases, in which case you can put your child's account in a Family and enable the purchase of the subscription for their account.

The other way to uprgrade from Live Gold to Game Pass Ultimate would be to buy a 25-digit Game Pass Utimate card and redeem it in your child's account, so the time he has of Gold will convert to Ultimate.

The Microsoft account balance can only be used to purchase 360 content from a 360 console, but you should still be able to make the purchase using a credit card as long as you're not on a child account. Have you also tried making the purchase from the
console itself?
