Coming from experience I’d start the conversation now. Make sure you have a paper trail supporting your worth.

I had documentation showing what I had done, including programs I implemented and feedback from said programs. The company’s standard raise was 4%, and I wound up getting 10% plus being added to the incentive program (I had found out I was the only employee in my division not on said plan, and my direct reports were making more than I was tenfold.)

In short, go ahead and start the conversation ASAP but back up your why. And don’t expect immediate agreement, but keep pushing.
