Rental Losses, Real Estate Professionals and Short-Term Rentals
When a rental loss offsets your other income: the $25,000 allowance and its phase-out, real estate professional status, the short-term rental rule, the seven material participation tests and the 3.8% net investment income tax.
A rental is a passive activity, so a rental loss offsets only passive income and the rest carries forward — unless one of the exceptions below applies (IRC §469(b), (c)(2), (i) — 26 U.S.C. § 469).
The $25,000 allowance
If you actively participate — you approve tenants, set rents and approve repairs — up to $25,000 of rental loss offsets other income. It phases out by 50 cents a dollar of modified adjusted gross income over $100,000, and is gone at $150,000. Married filing separately and living together, there is none (IRC §469(i) — 26 U.S.C. § 469). A trust gets no allowance at all.
Real estate professional status
If more than half your working time AND more than 750 hours a year are in real property businesses in which you materially participate, your rentals are not automatically passive; with material participation in the rentals themselves, the loss offsets wages and other income in full (IRC §469(c)(7); Treas. Reg. §1.469-9 — 26 U.S.C. § 469, Treas. Reg. § 1.469-9). For a married couple one spouse must qualify alone. With more than 500 hours in the rentals, the rental income is also outside the 3.8% tax (Treas. Reg. §1.1411-4(g)(7) — Treas. Reg. § 1.1411-4). Keep a contemporaneous log — the IRS and the Tax Court both ask for one.
Material participation
Material participation is one of seven tests (Treas. Reg. §1.469-5T(a) — Treas. Reg. § 1.469-5T). The ones rental owners use most:
- More than 500 hours in the activity during the year.
- Your participation is substantially all the participation by anyone, including people who are not owners.
- More than 100 hours, and not less than anyone else.
- You materially participated in five of the last ten years.
Short-term rentals
A rental whose average stay is 7 days or less is not a "rental activity" for these rules (Treas. Reg. §1.469-1T(e)(3)(ii)(A) — Treas. Reg. § 1.469-1T). With material participation, its loss is not passive — without real estate professional status.
Losses carried forward
Suspended losses carry forward on Form 8582 and are released in full when you dispose of your entire interest in a fully taxable sale to an unrelated person (IRC §469(g) — 26 U.S.C. § 469). Enter last year’s carryforward and the plan applies it.
The 3.8% net investment income tax
Rental income is net investment income unless it is from a trade or business in which you materially participate, or you meet the real estate professional safe harbor. The tax is 3.8% of the smaller of that income and your modified AGI above $200,000 (single) or $250,000 (married filing jointly) — thresholds the law does not index (IRC §1411(a)(1), (a)(2), (b). — 26 U.S.C. § 1411).
The 20% deduction
When your rentals are a trade or business — for example under the 250-hour safe harbor for rental real estate enterprises (Rev. Proc. 2019-38) — 20% of the qualified business income is deductible. Above the income threshold it is limited to the greater of 50% of W-2 wages or 25% of wages plus 2.5% of the unadjusted basis of your buildings, which Seayora takes from the register (IRC §199A(b)(2), (b)(3), (e)(2) as amended by P.L. 119-21 §70105; Rev. Proc. 2024-40; Rev. Proc. 2025-32 §4.26. — Public Law 119-21 (H.R. 1, 119th Congress), 26 U.S.C. § 199A, Rev. Proc. 2024-40, Rev. Proc. 2025-32).
