With 1031 exchange for personal property going away, I wouldn't be surprised if the days of upgrading planes every year or two is over. It used to be that owners would put their planes in an LLC, depreciate it over a couple of years, and once it's fully depreciated do a 1031 exchange for a new plane and take depreciation again. The new tax law takes away 1031 exchanges for personal property, retaining it only for real estate. Now if you sell your plane after depreciating it the IRS will "recapture" that depreciation and tax you on it as income. I bet this puts a big dent in aircraft sales going forward.
ho are leasing them back to do that.
In a partnership, you would have much lower hourly expenses, that's for sure.
@wayne has a spreadsheet that lays it all out nicely.
