So I'm going to be running a pathfinder society adventure tomorrow that is Tier 1-5. So it can either be run 1-2 or 4-5. My highest level PC is level 3.2, and I also have a 1.2 registered PC.
Am I allowed to used the chronicle sheet for my level 3 character if the session gets run as 4-5? Or would I have to use the 1-2 version on that character? Could I save the sheet until my primary character gets to level 4, or would I have to put it on my level 1 character since it is in the correct range for a 1-2 sheet?
The subtier for which a GM’s character receives credit depends on the character’s level. If a GM with a 1st-level rogue runs a Tier 1–5 scenario using Subtier 1–2, she takes a Subtier 1–2 Chronicle sheet for her 1st-level rogue. If she instead runs a Tier 1–5 scenario using Subtier 4–5, she still takes a Subtier 1–2 Chronicle sheet, as her PC clearly falls within the lower subtier.
Should a GM receive a Chronicle sheet that indicates her character is between subtiers (for example, if she runs a Tier 1–5 scenario with Subtiers 1–2 and 4–5 but has a 3rd- level character), she must always play down, taking a Chronicle sheet for the lower subtier. This rule is meant to balance the fact that the GM’s character does not have to expend any resources or risk death while gaining a Chronicle sheet for running a scenario.
Can I save the sheet until my level 3 character reaches level 4?
I'm not sure why you want to wait however.
Presumably to get the higher tier rewards, rather than effectively 'playing down'.
The only time you wait to apply GM credit is when the PC is out of tier for the scenario/module entirely.
...it's frustrating that my character is going to get around 1,000 less gold because I chose to help out my local PFS group when they were low on GMs for an event instead of playing my PC like I was planning.
No, unfortunately it will be applied to whatever character you choose immediately.
Or he can choose to not take his DM reward this time and run the game again in the future, when the circumstances are perfect for his to apply it the way he wants.
Unless you know something I don't and you have to take your DM chronicle the first time or else you can never get it (which I think is not the case).
I think I'm just going to apply it my level 1 PC, and get them to level 2 and stay on track for wealth by level with my level 3 PC

You actually aren't losing out on as much gold as you might think. Since you didn't play the scenario, you didn't have to use any resources. A single potion of fly is 1/3 of the gold you didn't get - not to mention all those charges from your wand of cure light wounds.
To get your character back "on track", just GM a couple more scenarios and apply the credit to that character. You'll soon have higher than average wealth.
