I'd like to be able to exclude that income from 2017 but am not sure if that will be a problem because it won't match with what the company for which I was consulting filed for my 1099-MISC. I just noticed that although my invoice date was January 2, 2018 and they appear to have cut the check on January 5, 2018, they back-dated the actual check itself to December 29, 2017. So if they're using the accrual method, do I need to do the same?
