Passive income is money that keeps arriving from something you own or set up once, without you working for it each time. The US tax office uses a tighter version of the phrase, and it's worth knowing before you read any list of ideas. By that rule a lot of the usual suggestions don't qualify, including savings interest, dividends, and a book you wrote yourself.
We make an app that pays people for small jobs on their phone. That gives us an obvious reason to want you to like this category. Read us with that in mind. Nothing here is tax or money advice. We won't tell you what you'd earn either, for a reason you'll find at the end.
Why you keep seeing the phrase passive income
It turns up in money videos and adverts all the time, and that isn't an accident. The phrase sells, so people sell it, and a few of them get sued for doing it badly.
In March 2025 the US Federal Trade Commission took action against a company called Click Profit. The promise was guaranteed passive income from an online business. The FTC's consumer protection director said the company "misled consumers by falsely promising them guaranteed passive income". According to the complaint, what people lost came to 14 million dollars or more.
The legal definition of passive income almost nobody quotes
In the United States the phrase has a written meaning that's free to read and surprisingly short.
IRS Publication 925, the 2025 edition, says there are two kinds of passive activity. The first is "trade or business activities in which you do not materially participate during the year". The second is "rental activities, even if you do materially participate in them, unless you are a real estate professional". Nothing else is on the list.
Two things are worth holding on to here. This is a tax rule, so it decides how income and losses get reported rather than how people talk. And that phrase, "materially participate", is the hinge the rest of this turns on.
The 500 hour line that decides what is passive
The rule behind the phrase is 26 CFR 1.469-5T, and it puts a number on it. You took part materially if you worked on the thing "for more than 500 hours during such year".
500 hours a year works out at about ten hours a week, since 500 divided by 52 is 9.6.
That hands you a test you can run on anything somebody sells you. If it needs more than roughly ten hours a week, the rulebook that defines the term won't call it passive. It's a job.
What the IRS rule excludes from passive income
Publication 925 also lists what doesn't count as passive activity income, and two of those exclusions matter a lot here.
The first is portfolio income, which the IRS defines as "interest, dividends, annuities, and royalties not derived in the ordinary course of a trade or business". Money in a savings account pays interest, and shares pay dividends, so neither one is passive activity income under this rule.
The second exclusion is sharper. Income from "a patent, copyright, or literary, musical, or artistic composition" is out too, where "your personal efforts significantly contributed to the creation of the property". A book you wrote, a song you recorded, a photo you took.
In everyday speech, calling your savings interest passive income isn't a lie, and it's a normal way to talk. The problem is that most of the pages we counted recommend savings interest or dividends and never mention the rule that excludes them, as the next section shows.
What the top passive income pages say, counted
On 22 September 2026 we fetched the ten pages that came back for "what is passive income definition explained". We stripped them to plain text and searched every one of them for the same words. All ten loaded, and anyone can repeat it.
- 10 of 10 present savings interest as passive income, and 9 of 10 present dividends.
- Only 3 of 10 mention portfolio income, the rule that excludes both.
- That leaves 7 of 10 recommending interest or dividends without ever mentioning the exclusion.
- 6 of 10 mention the IRS, 2 of 10 name Publication 925, and none cite section 469.
- 2 of 10 give the 500 hour figure.
- They ran from 2,044 to 9,723 words.
We also counted how much they repeat each other, against a fixed list of 18 stock ideas. Renting out property is on all ten, a savings account is on nine, and an ebook is on eight.
| Idea | On how many of the ten | What the IRS rule makes of it |
|---|---|---|
| Rent out a property | 10 | Passive. Rentals count even when you do the work, unless you're a real estate professional. |
| Money in a savings account | 9 | Not passive. Interest is portfolio income. |
| Write and sell an ebook | 8 | Not passive, if you wrote it. Income from what your own effort created is excluded. |
| Dividend shares | 7 | Not passive. Dividends are portfolio income. |
| Affiliate links | 7 | A business. Above 500 hours a year, not passive. |
| Royalties | 7 | Not passive, where they don't come from a trade or business you run. |
| A YouTube channel | 6 | A business. Same 500 hour test. |
| An online course | 6 | A business, and you made the course. |
Three ideas show up on eight or more of the ten pages. One of them is passive by the rule, and the other two are things the rule throws out.
What each passive income idea costs before it pays you
The lists tell you what to do, but rarely what it costs first, in money or in hours.
| Idea | Money up front | Before the first payment | After that |
|---|---|---|---|
| A rental | A lot. We won't guess a figure. | Buying it first | Work, or you pay someone to do it |
| Savings or shares | Whatever you put in | None | None |
| A YouTube channel | Little, past a phone | 1,000 subscribers and 4,000 qualified watch hours in 12 months | Keep posting |
| A Kindle book | Little, past your own time | Writing it, then the price band below | Marketing it |
| An online course | Your time, sometimes money too | Building it | Answering students, keeping it current |
| An app running in the background | None | Minutes to install and switch on | None. It runs while the device is on. |
Two of those bars are published by the companies themselves. YouTube says a channel joins its Partner Program at "1,000 subscribers with 4,000 qualified watch hours in the last 12 months". The other route is 1,000 subscribers and 10 million Shorts views in 90 days. Below either bar, a channel can't join the Partner Program.
Amazon says a Kindle book gets the 70 percent rate only inside a price band. From 7 July 2026 that band runs 2.99 to 12.99 dollars on Amazon.com. A book priced outside it can't use the 70 percent option, and Amazon's other option pays 35 percent.
We can't give you a figure for what a rental costs to buy. We couldn't find one we trust, and we're not inventing one.
Who actually gets passive income
Each year the US Federal Reserve asks nearly 13,000 adults about their money. In the survey for 2025, published in May 2026, 37 percent said they got interest, dividends or rental income.
By age it splits hard. Among adults aged 18 to 29, 24 percent got any of it, against 50 percent of people aged 60 and over.
That's the quiet part of most idea lists. They're written for somebody who already has money.
Which passive income ideas actually run without you
Put the two tables together and the ideas fall into three piles.
Ones that need money you already have: rentals, shares, bonds, savings. They really are low effort once bought, and that's the point. The effort got replaced by capital.
Ones that need hours, for months, before anything arrives: a channel, a course, a blog, a book. The 500 hour line says what these really are, and so does YouTube's own threshold.
Ones that need neither. It's a small pile, and a background app is what sits in it. You install it, you switch it on, and it works while your device is online. That's the lane we build in. In PaysFair each way of earning is its own switch. Every one of them stays off until you turn it on. There's more in our guide to sharing your connection.
Be straight about what this pile is and isn't. It asks almost nothing of you, and low effort tends to mean small money. It earns nothing while your device is off. If your internet plan has a data cap, sharing uses part of it.
Passive income outside the US
The IRS rule is American, and other countries write their own. In the UK, HMRC gives "up to £1,000 each tax year in tax-free allowances for property or trading income". If you have both kinds of income you get £1,000 for each. Below that, HMRC says you may not need to tell them at all.
Your own tax office publishes its own rules, and they're free to read. That beats any list you'll find, this one included.
What this page can't tell you about passive income
We won't tell you what you'd earn, and the reason is worth reading. The FTC keeps a notice of what counts as deceptive in exactly this market. One line says that showing an earnings figure implies the figure is typical. To use one you'd have to say how many hours those earners put in, and what share of people got there.
Another line says it's deceptive to claim a money-making opportunity is "risk-free or involves little risk". You'll get no earnings numbers from us then, on this page or anywhere else on this site.
This isn't tax advice either, and the IRS rule only decides how income and losses get reported. If that touches your own return, ask someone qualified where you live.
One more limit: our count covered ten pages, for one search, on one day, from one country. It's a snapshot, not a ranking.

Questions people ask about passive income
How do I actually start with passive income?
Start by sorting the ideas instead of picking one. Almost every idea on the popular lists needs either money you already have, or months of unpaid hours. Rentals, shares and savings are the first kind. A channel, a course or a book is the second kind: YouTube, for example, wants 1,000 subscribers and 4,000 qualified watch hours inside 12 months before a channel can join its Partner Program. A third and much smaller group needs neither, and that is where background apps sit. Work out which of the three you can afford first, in money or in hours, and the choice gets a lot smaller.
Is passive income legitimate, or is it all a scam?
Both exist, and the phrase itself is neutral. It has a written legal meaning in the United States, set out in IRS Publication 925, and plenty of ordinary income falls under it. The category also attracts sellers: in March 2025 the US Federal Trade Commission took action against a company called Click Profit over promises of guaranteed passive income, and the complaint put what people lost at 14 million dollars or more. The FTC has also stated that calling a money-making opportunity risk-free is deceptive. A promise of guaranteed returns is the warning sign, not the phrase itself.
What is a good option if I am a student with no money?
Most of the standard advice does not apply to you, because most of it assumes capital. The Federal Reserve measured this: in its survey for 2025, 37 percent of US adults received interest, dividends or rental income, but only 24 percent of adults aged 18 to 29 did. Without capital your real options are the ones that cost hours rather than money, or the small group that costs neither, such as an app that runs in the background while your device is on. Nobody can tell you what any of them would pay you.
Is rental income or dividend income better?
They are treated differently, which surprises people. Under the IRS rule a rental counts as a passive activity even if you do the work yourself, unless you are a real estate professional. Dividends do not: the same publication classes them as portfolio income and excludes them from passive activity income. That is a tax distinction about how things get reported, not a ranking of which one pays more, and this page is not tax advice. Which is better for you depends on capital, on hours and on your own tax position, so that question belongs to someone qualified.
Can I have lots of small passive incomes instead of one big one?
You can, and it is a common question, but the arithmetic is usually harsher than it looks. Each source carries its own setup cost in money or hours, and those costs add up faster than the income does. The IRS rule has a version of this problem built into it: separate activities you spend more than 100 hours on each can be added together, and once the total passes 500 hours in a year you have materially taken part in them. Spreading your effort widely does not make the effort passive.
