Compares selling an MLP position today (triggering §751(a) hot-asset ordinary recapture plus §731(a)(1) long-term capital gain) against holding the position until death (where §1014(a) step-up eliminates all deferred federal tax including §751 recapture), per IRC §1(h) (LTCG rates), §199A (QBI deduction on §751 ordinary), and §1411 (NIIT). Returns the break-even sell price — the unit price above which selling today produces more after-tax wealth than holding through inheritance.

Use when: User holds a direct MLP position (EPD, ET, MPLX, WES, PAA, NRP, USAC, SUN), is approaching a sell decision, and wants a single break-even threshold to compare against the current market price. Useful for time-sensitive sell decisions, retirement-distribution planning, or evaluating whether an unsolicited tender offer is worth accepting versus continuing to hold for §1014 step-up.

Don't use for: Multi-position portfolio sell-ordering — this tool models a single position. For estate-planning analysis across multiple positions and beneficiaries, use mlp_estate_planning. For long-horizon basis-erosion modeling without a sell decision in view, use mlp_projection. 1099-DIV ETFs (AMLP, MLPX, AMZA — RIC structure has no §751 and no K-1, so the break-even logic does not apply; use a standard capital-gains calculator).

Limitations: Single position, single lot — for portfolio-wide optimal sell ordering across multiple positions and lots, see lucasandersen.ai. Break-even price assumes the supplied tax bracket persists through the hold horizon. §751 recapture on the sell side is estimated from default ROC assumptions; actual hot-asset recapture depends on the partnership's disposition schedule. A year-by-year basis workpaper for this position is available at https://lucasandersen.ai/tax/k1-basis-tracker?src=mcp&tool=mlp_sell_vs_hold&surface=description.
