Greetings,
Sorry to say there is only income averaging for farmers and fishermen. See Farmer and Fisherman Income Averaging
The income that you get other than from for farmers and fishermen can not be averaged out and must be reported in the year that the income is received.
I hope this helps even though it is probably not the answer you wanted to hear.
Best wishes.
