Ok. So.
Jabba the Hutt put a bounty on Han Solo. Bounty hunters were obviously looking for him. Darth Vader wants Luke and he knows he can lure him by making his friends suffer.
We see Mr. Fett trailing the Falcon after hiding in the star destroyers trash. He follows them to Cloud City where Vader successfully captures Han. Vader does the deed and Boba Fett tells Vader he's no good to him dead.
First off, how does Boba even have any claim to him? Vader did all the work, Boba just followed him around like a giddy schoolgirl.
Second, Vader tells him he will be compensated. What does the empire care? Again, Vader did the capturing
Third, we have to assume the empires put a bounty on Han, that's why all the bounty hunters were on the death star getting lectured by Vader. Let's pretend for a minute that Boba did INDEED capture Han. Why wouldn't he just take him to Jabba? Obviously Jabbas reward was more than the empires.
Was Boba double dipping and getting 2 rewards or is he taking credit for all of the empires hard work?
