MLP K-1 Tax Issues for Individual Investors: UBTI, Section 751 Recapture, and Multi-State Filings
A Master Limited Partnership pays cash quarterly but issues a Schedule K-1, not a 1099. Most distributions reduce your cost basis instead of being taxed, holding units in an IRA can trigger UBTI and a Form 990-T once income exceeds $1,000, and selling converts depreciation into ordinary income under Section 751 — taxed up to 37%.

NIL Collectives and 501(c)(3) Status: What IRS Memorandum AM 2023-004 Means for Donors
IRS Memorandum AM 2023-004 holds that most nonprofit NIL collectives fail the 501(c)(3) operational test because compensating student-athletes is substantial private benefit, not charitable activity — meaning donor contributions are often not deductible.
Why Most NIL Collectives Aren't Real Charities (and Your Donation Isn't Deductible)
The IRS memorandum AM 2023-004 concluded that NIL collectives paying 80-100% of donations to athletes confer substantial private benefit and fail the operational test for 501(c)(3) status, so contributions to them are generally not tax-deductible.
