1031 exchange depreciation recapture

[NJ4242]

I did an exchange with  the new property being less than the old, resulting in a 41k realized gain (boot), after selling expenses.  I entered the 41k as unrecaptured section 1250 gain. However, the federal tax due increased by 12K (29.2%). Isn't the max on recapture 25%?

Did it possibly kick in the NIIT? 

The gain attributable to the depreciation may be subject to the 25% unrecaptured Section 1250 gain tax rate. Additionally, taxable gain on the sale may be subject to a 3.8% Net Investment Income Tax.
