Almost nothing sold as passive income is free. Passive income is money that keeps arriving without you trading fresh hours for each payment: interest on savings, dividends from shares, rent, royalties, or profits from a business someone else runs day to day. Instead, each kind is paid for with money, effort or risk supplied earlier, usually some of each.

So the honest answer to what is passive income depends on who is asking. To a friend it often means money that takes little time; to a tax authority, a legal category with rules attached; to a seller, a promise that you will barely have to work.

What is passive income, in plain speech and in tax law

In plain speech, passive income means earnings that don’t depend on the hours you work this week. US federal tax law is far narrower: for 2025 returns, the IRS’s Publication 925 counts only businesses you don’t materially participate in and, with some exceptions, rental activities as passive, and generally classes interest and dividends as portfolio income.¹

That working definition is ours, and it asks what had to be put in first, not how the money feels to receive. An illustration: one friend earns interest on a savings account and does nothing for it; another spends Saturday mornings answering emails for her online shop. Both may call it passive, but only the first is right in the everyday sense; the second has a part-time job with irregular pay.

The practical lesson: when someone calls an income stream passive, ask which meaning they intend. “Little work” is a claim about your time; “passive” on a US tax form is a legal category with its own rules.

The tax label depends on the rules, not on effort

Whether income counts as passive for tax depends on the rules, not on how effortless it feels. Under US federal rules for 2025 returns, a business counts as passive when you don’t materially participate, and several of the IRS’s seven tests for that count hours: the best known is working in it for more than 500 hours in the year, roughly 10 hours a week. Rentals generally count as passive even if you work hard at them, unless you qualify as a real estate professional, and interest, dividends and royalties not earned in the ordinary course of a business are portfolio income, outside the passive category.¹

In the US, those categories carry consequences: losses from passive activities can generally offset only passive income, with unused losses carried forward to later years.² An illustration: a teacher who rents out a condo and spends weekends fixing it runs what feels like an active business, yet US tax law still calls it passive, while her colleague’s fund dividends take no effort and count as portfolio income.

In the UK, GOV.UK guidance sorts the same income by source instead, with separate rules and tax-free allowances for savings interest, dividends and rental income. Each allowance applies per tax year, which in the UK starts on 6 April.³

The practical point: before counting on a tax break or tax-free amount, check how your tax authority treats each stream, or ask a qualified tax professional. Outside the US and UK, national rules differ again.

Where passive income comes from: money, earlier work, or both

Passive income comes from three places: capital you put to work, such as savings, shares or property; work done earlier, such as a book; or a mix, such as a rental that needs money and management.

Myth

Passive income is money for doing nothing.

Fact

Each kind is paid for with money put in, work done earlier, ongoing upkeep or risk, and US tax law uses the word more narrowly still.

Interest is what a borrower pays to use your money, and rent is what a tenant pays to use your property. A dividend is part of a company’s earnings paid out to shareholders. The SEC’s Investor.gov notes that growth stocks rarely pay dividends at all, and that share prices fall as well as rise, so you can lose money you invest in stocks.⁶

Because income from capital is a percentage of the money behind it, run the arithmetic backwards: divide the yearly income you want by a yearly rate. The table is our hypothetical example in US dollars, before tax, fees and inflation, assuming you spend only the payments; the rates are not quotes or forecasts, and real income can be lower.

At these rates, even a modest monthly top-up from savings or dividends needs a five- or six-figure balance first. The income is real, but it is rent on money you already have, and that balance can shrink, as our guide to how stocks, bonds and funds gain and lose value explains.

1. Capital: interest, dividends and rent are paid on money you put in, and shares can fall in value
2. Up-front work: a book or other creative work is made before it earns any royalties
3. Upkeep: finding tenants, repairs and tenancy paperwork keep coming after the first rent
4. Risk: payouts, prices and sales can drop, and some offers sold as passive income are scams

The habit worth keeping: if a pitch promises steady income but never says how much money has to go in first, it has skipped the most important number.

Royalties and rentals: the work comes first, and keeps coming

Income from creative work and property is often called passive, but the work comes before the money, and for property it keeps coming. In the Authors Guild’s 2023 survey of published US authors, the median respondent earned about US$2,000 from books in 2022 once advances, royalties and licensing fees were counted.⁷

The survey was run by a writers’ advocacy group, and most respondents did not see themselves as full-time authors, so it describes the published authors who answered, not all writers. At that level, books are a top-up rather than a living. It also shows how a royalty works: a delayed payment for work already done, sized by sales the author does not control.

Property mixes capital and labor. GOV.UK’s tax guidance for landlords lists work a landlord may still do even when letting is not their main job: collecting rent, arranging or carrying out repairs, maintaining common areas, preparing the property between lets, advertising for tenants and arranging tenancies.⁵

An illustration, not a case: a tenant texts late on a winter night that the heating has failed, and the fix falls to you or to someone you pay. Paying a manager turns your hours into a cost; it lowers the income rather than removing the work.

Seen that way, many so-called passive projects are side hustles with late pay.

“Passive income” as a sales pitch: what US regulators alleged

Passive income has been the hook in several online-store offers that US regulators have taken to court. In March 2025 the Federal Trade Commission (FTC) sued Click Profit, alleging that it promised “passive income” from online stores it would build and run for buyers, while most buyers lost their entire payment.⁸

The study

Limited evidence

The FTC's case against Click Profit, 2025

The FTC alleged that Click Profit charged buyers a management fee of at least US$45,000, plus more for inventory, for online stores that its AI-powered system would supposedly turn into large sums of passive income. According to the complaint, after Amazon’s fees more than a fifth of the company’s stores there earned no money and another third made less than US$2,500 in gross sales over their lifetimes, and once the company’s own fees were counted, most buyers never recovered their costs.⁸ In August 2025 the operators agreed to a settlement whose proposed orders permanently ban them from selling business opportunities.⁹

These are allegations about one company, settled without a trial, so they show how such schemes can work, not how common they are. The FTC has settled two similar online-store cases: in 2024 with the owners of Automators AI, which it said promised “passive investment income”, and in 2025 with the owner of FBA Machine, formerly Passive Scaling.¹⁰¹¹

Our reading of why the pitch works: it sells the outcome and quietly moves the costs. The buyer supplies the capital as fees, the seller claims to supply the work, and the risk stays with the buyer. It is the usual bill for passive income, reordered so the seller is paid first.

Four questions to put to any passive income offer

Four questions sort most offers: how much money goes in, how many hours it really takes, what you could lose, and who is selling it and how they are paid. Each drags one of the costs above into the open; the question a seller dodges is the one to press.

Regulators flag the same gaps: a 2013 SEC investor alert on pyramid schemes lists offers of easy money or passive income for little work, such as recruiting others, as a red flag.¹² The Financial Conduct Authority (FCA), the UK regulator, says get-rich-quick schemes promise high returns not usually available from traditional investments, and urges caution about unexpected contact and pressure to act quickly.¹³

Run the questions on two offers. A savings account gives dull, clear answers: your deposit, almost no hours, a rate that can change, a provider you can check. The Click Profit stores, as the FTC described them, gave alarming ones: a fee in the tens of thousands of dollars, a seller claiming to do the work, the risk of losing everything, and fees paid before any sales.

In the US, the FTC’s Business Opportunity Rule puts some answers in writing, but only for offers that fit its definition: broadly, you pay to start a new business and the seller says it will supply locations, outlets, accounts or customers, or buy back what you make.¹⁴ Sellers it covers must give you a one-page disclosure document at least seven days before you sign or pay, and any earnings claim must come with the number and percentage of buyers who did at least that well, plus written proof if you ask.¹⁵

Questions to answer in writing before you pay

• How much money goes in, and where exactly does it go?
• How many hours will it take in the first year, and each year after?
• What could go wrong, and could I lose all of it?
• Who is selling it, and do they earn from my fees or from my results?
• For a US business opportunity the FTC rule covers: did I get the disclosure document at least seven days before paying?
• For an investment: is the firm or person registered in the US with the SEC, FINRA or a state, or listed on the FCA register in the UK?
• Have I searched the company name with words such as scam or complaint, and talked to someone I trust?

Reporting a doubtful offer and finding help

Some situations need action today, debts deserve advice within weeks, and a yearly check covers the rest. The ordering is ours; each route comes from the organization named.

• Today, if you think you have paid a scammer: send no more. In the US, the FTC suggests reporting the offer to the attorneys general of your state and the promoter’s state, and to the FTC at ReportFraud.ftc.gov.¹⁶ In the UK, the FCA asks people to report suspected scams to it, and to Report Fraud if they have lost money; it warns that victims may be approached again by “recovery room” scammers offering to get money back for a fee.¹⁷ The UK government’s anti-fraud campaign adds that anyone who has lost money should tell their bank or payment provider as soon as possible, and that in Scotland fraud is reported to Police Scotland on 101.¹⁸ Elsewhere, go to the national police or financial regulator.
• Today, if money worries come alongside thoughts of self-harm or suicide: the National Institute of Mental Health, in the US, directs people to the 988 Suicide & Crisis Lifeline, which takes calls and texts, and to 911 when someone’s life is in immediate danger.¹⁹ In the UK, the NHS advises calling 999 or going to A&E if anyone’s life is at risk, or if you feel unable to keep yourself safe; Samaritans offers a free listening service on 116 123, and in England NHS 111’s mental health option gives urgent help.²⁰ Outside the US and UK, dial your local emergency number.
• Within a few weeks, if a scheme has left you with debts: credit counseling organizations in the US are usually non-profit and give advice free or cheaply, the Consumer Financial Protection Bureau notes, though counselors may charge for some services; it also passes on FTC findings that some debt management plan providers have defrauded people.²¹ UK government guidance on paying off debts sends people to MoneyHelper for details of free debt advice services.²² Elsewhere, start with a government or non-profit debt service that charges nothing.
• Before a large commitment: Investor.gov, the SEC’s site, advises confirming that any financial professional you use holds a license, and notes that unlicensed, unregistered people commit much of the investment fraud in the US.²³ UK readers can use the FCA’s Firm Checker to see if a firm is authorised, and its Financial Services Register to check an individual.²⁴ Elsewhere, check with your national financial regulator. For choices that depend on your own finances, a regulated financial adviser can review your numbers, and a tax professional can explain how each stream would be taxed where you live; ask either one how they are paid.
• Every year: put each income stream through the four questions again; setting up a monthly budget shows whether it pays its own costs.

The bottom line

The useful question about any income stream is not whether it is passive but what it is paid for: money, earlier work, upkeep or risk. For tax, the label follows the rules, not the effort, and US law draws it narrowly. When an offer’s main selling point is how little you will have to do, ask what goes in, what could be lost and how the seller is paid, and check the seller before you pay.
