Planning isn't possible without having the 2025 software available on September 26th?  I remember back in the day when we would have to walk uphill, both ways, to get a tax projection done without the aid of any software.  Personally, if I needed a projection done on September 26th I would use the 2024 tax planner and tweak for anything that the software hasn't updated yet for 2025.  I never load the following year software until at least early January ----------- when it is "starting" to get closer to being a functional software.
