Due date if paying annually is Jan 15, but you have grace period until Feb 15, and you do not get bill until after the annual meeting. You can sign up with MS accounting to do monthly withdrawals from checking account (you need a US account for that purpose), and there is no fee or interest charge for doing so. Many prefer that method while many just like to pay annually, including because they can pay with credit card and get the credit card points, or pay with Disney gift cards purchased at a 5% discount at Target when they have a Target Red Card charge card, although I vaguely recall mention that Disney is now limiting the number of gift cards you can use to pay dues to one or two.
