Did anybody else notice? If you have a loss of 900 million and then make 600 million per year in gain, your capital loss write off lasts exactly 1.5 years. And that is only if the loss shares the same type of long-term or short-term status as your gain. If the gain is normal income, then you only get to deduct $3000 per year as you consume the carry-over.

I think if Trump's 900 million dollar loss has lasted 18 years, then he must have worked it out so he only makes a gain of 50 million per year. And his actual income as wages must effectively be zero.

He has structured his gain and income so it is pushed off into the future. Maybe he is waiting until he can lower the top tax rate to realize the income. If he can get the estate tax repealed then he can leave it all to his kids with ZERO tax.
