Is this a multi-member LLC? If no, stop reading now. Nothing below applies to your situation.
If yes. Are the owners/partners of the multi-member LLC exactly the same as the owners of the property before anything was transferred to new ownership?
If yes, then it's physically impossible for a business to own assets, before that business existed. The start date of the multi-member LLC *must* be on or before the date the first asset was placed "in service".
Assuming the same people listed on the title before the transfer are the same people that own the LLC, that means you don't have a reportable transaction on the tax front. Just make the start date of the multi-member LLC on or before the first asset is placed in service, and it will all work out fine, as it should.
