Excess Business Interest Expense 163(j)

[Tzvi Nussbaum]

I recently reviewed my tax return for 2018 prepared by my CPA and noticed that the amount deducted this year for depreciation was significantly less than years prior.  He used the Excess Business Interest Expense form 163(j).  The losses are significantly diminished as a result.  Does this apply to passive investors, active investors, or both?  Is this affected by taking bonus depreciation?  My wife is classified as an active real estate investor while I am passive.  Does anyone have any insight to this?
