A client asked us last week if her single-member LLC could become a multi-member LLC without triggering a partnership return.
She wanted the stronger asset protection that comes with multi-member status, but she didn't want the extra tax filing. Short answer: yes, in the right setup.
A single-member LLC is easier at tax time (just add it to your 1040), but in most states it offers weaker charging order protection. A multi-member LLC is stronger from an asset protection standpoint, but it triggers a partnership return every year. New form, new deadline (March instead of April), extra K-1s, bigger CPA bill.
There's a way to get both.
If you and your spouse own the LLC together and you're in a community property state like Washington, your LLC is considered single member despite the multiple members. If you want the stronger protection of a multi-member LLC, but the tax simplicity of a disregarded entity, gifting a piece of the LLC to a grantor trust (an IDGT/SLAT/SPAT, usually for kids or a parent) keeps everything disregarded because the trust's income flows back to you anyway. Multi-member protection, single 1040.
In a non-community property state like Oregon, spouses owning an LLC directly get treated as a partnership by default. Same fix works though. Hold the membership interests through disregarded grantor trusts and the whole structure collapses back to one tax filing.
The end result: multi-member charging order protection, no partnership return, lower CPA bill.
For our client, this meant she could get the protection upgrade she wanted without adding a March deadline to her calendar.
