Definition
Passive income for tax purposes is income from a *passive activity* as defined by Section 469 of the tax code. Only two things qualify:
- Rental activities — income from renting out real estate or equipment, which the tax code treats as passive *by default*, even if you spend real time on it (special rules exist for real-estate professionals and short-term rentals).
- A trade or business in which you do not materially participate — for example, a silent-partner stake in a friend's restaurant, or a limited-partnership interest where you put up money but don't work in the business.
Everything else that people casually call "passive income" falls into other buckets:
- Portfolio income — dividends, interest, capital gains, royalties, and annuity income from investments. This is its own category, *separate* from passive income.
- Earned (active) income — wages, salaries, and self-employment earnings.
The reason the boundary exists is the passive activity loss (PAL) rules: losses from passive activities generally may only offset income from passive activities. Congress drew the line in 1986 to stop taxpayers from using paper losses (often from real-estate shelters) to wipe out their salaries and investment income — so the definition of "passive" is deliberately narrow and the walls between buckets are deliberately high.
The short version: to the IRS, "passive" ≈ rentals plus businesses you don't materially work in. Dividends and interest are portfolio income — a different bucket with different rules. See is dividend income passive income? for the dividend-specific view.
Why It Matters
Losses are quarantined by bucket. A passive loss — say a rental property that runs $8,000 in the red after depreciation — generally cannot offset your wages or your dividend income. It can only offset *other passive income*, and any unused amount is suspended and carried forward until you either generate passive income or dispose of the activity. (A limited exception lets many active-participation landlords deduct up to $25,000 of rental losses against other income, phasing out at higher incomes.)
Material participation is the dividing line for businesses. The IRS applies a set of material-participation tests — the best known being more than 500 hours of work in the activity during the year. Pass one and the business income is *active*; fail them all and it's *passive*. The same K-1 income can land in either bucket depending on your hours.
Passive income still isn't cheap income. Passive income is generally taxed at ordinary rates, and — like portfolio income — it can be hit by the 3.8% net investment income tax (NIIT) at higher incomes. The favorable 0/15/20% rates belong to qualified dividends and long-term capital gains, which are portfolio items. "Passive" describes *how you earned it*, not *how it's taxed*.
Self-employment tax usually doesn't apply. True passive income (rentals, non-participating business stakes) generally escapes self-employment/FICA tax — one trait it shares with dividends and interest.
The Three Buckets at a Glance
| Income type | Bucket | Typical tax treatment |
|---|---|---|
| Wages, self-employment | Earned | Ordinary rates + payroll tax |
| Rental profits | Passive | Ordinary rates; no SE tax; NIIT possible |
| Business (no material participation) | Passive | Ordinary rates; NIIT possible |
| Dividends | Portfolio | 0/15/20% if qualified, else ordinary; NIIT possible |
| Interest (savings, bonds, CDs) | Portfolio | Ordinary rates; NIIT possible |
| Capital gains | Portfolio | 0/15/20% long-term; ordinary short-term |
| Royalties (investment) | Portfolio | Ordinary rates |
The bucket controls which losses can touch which income — the rate is decided separately, mostly by the qualified/ordinary and long-term/short-term distinctions.
Example
Meet an investor with four income streams this year:
- $90,000 salary (earned)
- $4,000 of dividends from SCHD and JEPI (portfolio)
- $6,000 profit from a rental condo (passive)
- $10,000 loss from a limited-partner stake in a brewery they don't work in (passive)
The brewery loss can offset the $6,000 of rental profit — both are passive — wiping it out. But the remaining $4,000 of loss cannot touch the salary or the dividends; it is suspended and carried forward. The dividends are taxed under portfolio rules: the qualified portion (most of the SCHD payout) at capital-gains rates, the option-premium portion of the JEPI distribution at ordinary rates. The salary is taxed at ordinary rates plus payroll tax.
One year, four streams, three rulebooks — and the "passive" label did the sorting.
Common Mistakes
- Calling dividends and interest "passive income" on the tax side. They're portfolio income. The label matters because passive losses can never shelter them.
- Expecting a rental loss to cut tax on your paycheck. Outside the up-to-$25,000 active-participation allowance (which phases out at higher incomes) and real-estate- professional status, rental losses stay locked in the passive bucket.
- Ignoring suspended losses. Disallowed passive losses aren't gone — they carry forward indefinitely and are generally freed in full when you sell the activity. Track them; they're future deductions.
- Assuming REIT fund distributions are passive because real estate is. Owning VNQ or any REIT fund produces *dividends* — portfolio income — not passive rental income. Direct property ownership and REIT shares live in different buckets.
- Forgetting the NIIT. Both passive and portfolio income can incur the extra 3.8% net investment income tax above the income thresholds.
- Treating "no self-employment tax" as "no tax." Passive and portfolio income skip FICA but are still fully reportable, mostly at ordinary rates.
This is educational information, not tax advice. The passive-activity rules are among the most intricate in the code — material participation, grouping elections, and real-estate-professional status all turn on specific facts. Confirm your situation with a qualified tax professional.
FAQ
What income does the IRS consider passive?
Only two kinds: income from rental activities (passive by default, with exceptions for real-estate professionals and certain short-term rentals) and income from a trade or business in which you do not materially participate, such as a limited-partner or silent-investor stake. Dividends, interest, and capital gains are *portfolio* income — a separate category — and wages are earned income.
Is interest passive income?
Not for tax purposes. Interest is portfolio income, taxed at ordinary rates. It's "passive" only in the everyday sense that you don't work for it. The distinction matters because passive activity losses cannot offset interest income.
Are dividends passive income to the IRS?
No — dividends are portfolio income. They may still enjoy the lower qualified-dividend rates, but rental or business losses in the passive bucket can't shelter them. See is dividend income passive income? for the full breakdown.
Can passive losses offset dividend or wage income?
Generally no. Passive losses offset passive income only; the excess is suspended and carried forward. The main exceptions are the up-to-$25,000 allowance for active-participation rental losses (income-limited) and the release of suspended losses when you dispose of the entire activity.
Is rental income always passive?
Almost always by default, regardless of how many hours you put in — that's a special rule for rentals. The headline exceptions are qualifying real-estate professionals (who can treat rental activities as non-passive) and some short-term rental situations that are treated as a business rather than a rental activity.
Does passive income get taxed at a lower rate?
No — passivity by itself confers no rate break. Passive income is generally taxed at ordinary rates. The favorable 0/15/20% rates apply to qualified dividends and long-term capital gains, which are portfolio income. Passive income's perks are narrower: no self-employment tax, and the ability to absorb passive losses.
