The change was introduced in Trump's tax cuts, so I doubt he will reverse it.

Did the change take effect during his administration or after the tax cuts expired or rather after the income brackets also increased? That change was intentional so that the following administration if it wasn't the GOP would feel the heat of and get the blame fortaxes going up.

It took place during the administration.

I think this is the more important comment in that thread: https://news.ycombinator.com/item?id=42380764

"Note: these changes were signed into law in 2017 but came into effect in 2022"

Like I thought, changes were meant to be a time bomb if the GOP wasn't in control.

Thank you, I missed that and it’s important context. I’ve upvoted your comment for more visibility.

Do you have a reference where I can read more about this, specifically the timelines?
