What if you have an LLC that has one owner and rents 1/3 of a building to the owner’s 100% owned SSTB S Corporation. The other 2/3 of the property is rented to non related entities. the rental LLC qualifies as a trade or business.
The self rental would be treated as a SSTB similar to the S Corporation. Could the other 2/3 of the net rental QBI be treated as non SSTB QBI?
