Education, not tax advice. 2026 federal brackets. The 3.8% test uses modified AGI, estimated as your “other taxable income” plus the 2026 standard deduction ($16,100 single / $32,200 married) plus the gain. Unrecaptured §1250 gain is stacked on top of your other income and each slice taxed at the lower of its ordinary bracket or 25% (§1(h)(1)(E)); the remaining gain fills the 0/15/20% bands above that. Assumes the property was held more than a year, straight-line depreciation on the building, and that the 3.8% NIIT applies (it may not if you qualify as a real estate professional). No §121 home-sale exclusion, passive-loss carryforwards, AMT or state depreciation differences are modelled. Have a CPA confirm before you sign anything.
