I need to file tax extensions.
I already know I need to file Form 4868: Application for Automatic Extension of Time To File U.S. Individual Income Tax Return. I expect a refund, so I'm sending no payment with this.
However, my wife and I have two LLCs. We're the only members: we each have a 50% interest in each.
An extension to file these would be through Form 7004: Application for Automatic Extension of Time To File Certain Business Income Tax, Information, and Other Returns. Taken by themselves there would be profit on them that would pass through to us on our 1040, but, again, we are expecting a refund overall.
I've found elsewhere that single-member LLCs only need to file Form 4868, because (link):
Single member LLCs only need to file for a personal tax extension (IRS Tax Form 4868), which will extend both the personal and business tax deadline, since your LLC is a "pass-through entity" and your business tax return is part of your 1040 personal tax return on Schedule C.
This is basically the same situation my wife and I have -- it's our LLC, and passes through to our joint return.
I don't know if this is pertinent or not, but we have not made any election to become a disregarded entity.
Do I need to file form 7004 for our LLCs? I'd prefer not to, because I'd likely need to pay estimated taxes that would be refunded once our individual return goes through. Or maybe I'm missing the correct reason entirely.
