Computes a multi-year tax projection for a publicly traded MLP position, applying the IRS Partner's Basis Worksheet methodology (Lines 1-14) per IRC §705 (basis computation), §731(a) (distributions exceeding basis), §733 (basis reduction), §751 (hot asset recapture), §752 (liability allocation), §1014 (stepped-up basis at death), and §199A (QBI deduction). Returns year-by-year basis erosion, §751 accumulation, annual federal tax, terminal FMV, §1014 step-up value at death, and the break-even sell price.

Use when: User holds direct units of a midstream MLP (EPD, ET, MPLX, WES, PAA, NRP, USAC, SUN) and wants to model long-term tax outcomes — when basis reaches zero, total tax paid over the hold horizon, deferred tax eliminated by §1014 step-up at death, or the unit price at which selling matches holding through inheritance. Single position, single lot.

Don't use for: 1099-DIV ETFs (AMLP, MLPX, AMZA — these use RIC structure, pay corporate-level tax, and issue 1099-DIV instead of K-1; use a standard cost-basis calculator instead). Multi-position estate analysis — use mlp_estate_planning. Computing basis from actual K-1 data the user has in hand — use k1_basis_compute (single year) or k1_basis_multi_year.

Limitations: Single position, single lot — for multi-position portfolios and per-lot optimal sell ordering, see lucasandersen.ai. Federal-level only — does not include state-level basis adjustments or state estate tax. §751 recapture is estimated from default ROC assumptions; actual recapture depends on the partnership's hot-asset disposition schedule.

Maintained by Lucas Andersen, MS Finance, with direct positions in major midstream MLPs. Methodology auditable at lucasandersen.ai/methodology.
