A flat rate that's been trending down for years.
North Carolina applies a flat 4.50% income tax to capital gains, a rate that's been declining in recent years and may keep falling. For now, combined with federal and NIIT, an investment property sale reaches up to 28.3% (20% federal + 3.8% NIIT + 4.50% state).
The 28.3% splits cleanly into three pieces, and the state's share is the one most likely to shift going forward. The capital gains tax calculator can estimate a real sale, depreciation recapture included, using the current rate below.
A 1031 exchange defers all three layers of that 28.3% by reinvesting sale proceeds into a replacement property instead of taking a cash payout. Set up the exchange in the 1031 exchange calculator and get your deadline dates from the timeline calculator.
