SMLLC Tax election with CPA

[Shawn H.]

I created a Single member LLC at the end of last year. I called my CPA to ask about any consequences transferring from husband/wife to SMLLC (myself as the sole member). He mentioned that I would have to choose partnership or S corp? I told him it is single member and I selected disregarded entity when applying for EIN. He said I still had to choose partnership or s Corp within a certain amount of time after creating the LLC. Am I missing something?
