I/I'll give you that

I('ll) give you that

I concede that what you just said is true or likely. A: "I don't understand why you're so upset—I told you I'd be late." B: "OK, I'll give you that, but 3 AM isn't just a little bit late, and you woke the whole house coming in the door." The tax breaks for business might spur the economy a bit, I give you that, but it means our budget for public works will be a lot smaller next year.
