You can elect points up until either 2 or 3 months BEFORE the Year of the enrolled week. You can elect for the following year and borrow. You can bank up until either 4 or 6 months before the end of the year. For example looking at my 2026 weeks. I can elect points up until 31 October, 2025 for the 2026 year/points, I could elect and borrow from the 2027 points for a reservation in 2026 and I could bank those 2026 points into 2027 up until 31 August of 2026. Those 2026 points banked to 2027 would then be good for me for 2 years. The election window, banking window and expiration of banked points are all tied to status, we're Chairman's Club.
Here is a link the the Premier Status levels.
BTW, for MVC you can't deposit 24 months out. TRUE fixed weeks like Monarch, Harbour Point and Vail can be deposited 18 months out and anything that's floating, even for plus weeks where you still have to make a reservation, it's when you have the reservation number which is not going to that far out, maybe 12-15 months at the outside.
