etq - Being a bit testy aren't we? Since DEP is now gone in the history books the K-1 should be out when it is due - the first week of March. As an aside - FINAL broker 1099s are not due out until 3/18! I would expect you will have your K-1 beofre the final numbers from your broker.
I got mine in by the filing deadline even with the K-1 from EPD. EPD wasn't even the last one for me - TNH K-1 came in April about a week before tax filing deadline.
If you are investing in MLPs you have to expect to be filing in April, not February.
EPD has stated you can get online on March 22nd - 4 days after you get your 1099Bs. Or they will be mailed on 3/28 and you get them whenever. If you don't like waiting for K-1s or 1099s then sell both and you can file in February.
