Is $15k more (~15% increase over offer) too much to counter with on a job offer?

Can someone help me negotiate my salary?

I’ve been a federal employee my whole career until now. We can’t negotiate so I’ve never done this before.

I work in tech. I got an offer for $115k and a 5% bonus. Fully remote.

I currently make $140k flat, but not remote. I’m willing to make less for a job that allows me to work anywhere

How should I go about negotiating to get it a bit closer to what I make now tho?

Is it crazy to ask for $130k? Chatgbt said it is normal to counter with that but it seems like a lot so i just want to make sure.

Anyone have advice on the amount and how to have the conversation?

Industry is tech. I’m mid level.
