Hi, can you please tell which of these phrases sound correct?
I’m finished with the report.
I’m done with the report.
I’ve finished the report.
Many thanks,

All of them sound equally correct to me.
They all sound correct to my ears too, but I’m not a native speaker, you see. 
Me too, but you realise that they don’t necessarily mean the same thing? The last means finished writing it, whereas the first two can mean finished using it, or finished reviewing it, for example
Yes, the last one suggests that the subject himself or herself has just completed his or her report. The first two don’t convey the same idea, as their subjects may have carried out a different action on the report.
