SMLLC Tax Extension Deadline

[Mark S.]

If someone files an extension and has a single member LLC (SMLLC), is the LLC's extension due date 9/15 (or 9/16 this year) or 10/15?

Even though in most cases it’s a disregarded entity for tax purposes, in Kentucky we have a $175 minimum Limited Liability Entity Tax (LLET) so a return must be filed.

If my assumption is correct, SMLLC extension deadline is 10/15 and multi-member LLC extension deadline is 9/16/19. Is this correct?
