• What "passive" means to the IRS
  • Ideas that need time and a skill

Each idea on this page needs either your time up front or some money to start. You build something once, such as a template, a course, a photo library or a rental listing, and it can then earn with less of your time. How much less depends on the idea, so the question to ask is what each one takes to start and to keep running. Nothing on this page promises an amount: what you earn depends on demand, your price and the work you put in.

This page groups the ideas by what they need from you. Before you build anything, how to validate a business idea shows how to find out whether anyone will pay, and how to price your services helps you set the price.

What "passive" means to the IRS

The everyday meaning and the tax meaning differ. In the US, the IRS's topic on passive activities (last reviewed or updated September 24, 2026) says: "Passive activities include trade or business activities in which you don't materially participate." It adds: "In general, rental activities, including rental real estate activities, are passive activities even if you materially participate."

Whether one of your own income streams counts as passive for tax purposes is a question for an accountant. The word on a course sales page doesn't decide it.

Ideas that need time and a skill

  • Templates and digital downloads. Turn something you already make for clients, such as a spreadsheet, a checklist or a design file, into a product people can buy and download.
  • A course or a written guide. Teach a process you know well. Recording or writing it is the upfront work; updates and buyer questions continue after launch.
  • Photos, illustrations or music licensed through a marketplace. Each marketplace sets its own terms and its own share of each sale, so read them before you upload.

Ideas that need an asset

  • Renting out a room, a parking space or equipment. You need the asset, plus time for bookings, cleaning and repairs. In the US, the IRS's topic on rental income and expenses (last reviewed or updated September 24, 2026) says: "Cash or the fair market value of property or services you receive for the use of real estate or personal property is taxable to you as rental income."
  • Renting your car or tools through an app. The app takes the bookings, but you still handle wear, insurance questions and handovers.

Ideas that need money

  • Dividend-paying investments, or a stake in someone else's business. These need capital you can afford to tie up or lose, and the return isn't certain. Talk to a licensed financial advisor before you invest.

Ideas that stay partly active

  • Monthly service packages. Bookkeeping, website care or social media scheduling sold as a fixed monthly package. The work continues, but each client pays a fixed monthly fee on a set date instead of one-off project invoices.

Worked example: when does a template pay back your time?

Sample figures, not a sales forecast:

  • Time to build and test the template: 30 hours
  • Value you put on your time: $40 an hour, so the build costs 30 × $40 = $1,200
  • Price $29, less a sample marketplace fee of 10% ($2.90): $26.10 a sale
  • Sales needed to cover the build: $1,200 ÷ $26.10 = 45.98, so 46 sales

If you can't see a way to 46 buyers, change the product, the price or where you sell it before you build. Use the actual fee of the marketplace you pick.

Check done-for-you income offers before you pay

Some sellers promise passive income from a store or system they say they'll run for you. In the US, the FTC's consumer alert "Vetting a business or coaching opportunity before you buy in" (August 22, 2023) says: "Ask the seller to give you a copy of the legally required 1-page disclosure document." Among the things that document must do, it lists: "tell you if the seller is making a claim about how much money you can make. If they are, they also must give you an earnings claim statement."

Report what you earn

Money from apps and marketplaces still belongs on your tax return. The IRS's gig economy page (US, last reviewed or updated July 9, 2026) says: "You must report income earned from the gig economy on a tax return, even if the income is" not on an information return, or is "Paid in any form, including cash, property, goods, or virtual currency". Ask an accountant how this applies to you.

Where Billed fits

If one of your ideas is a monthly service package, Billed's invoice software page says: "For clients you bill on a schedule, set up a recurring profile once." It also says: "Clients can link a credit card to make recurring payments easier, and each recurring profile keeps its invoices and payments in one place."

When this guide isn't for you

If you need income within the next month, start with paid client work; the ideas here can take time to earn back what you put in. This page doesn't give tax, legal or investment advice.

Frequently Asked Questions

Does the IRS treat my side income as passive?

That depends on how involved you are. The IRS (US, last reviewed or updated September 24, 2026) says: "Passive activities include trade or business activities in which you don't materially participate." An accountant can tell you how that applies to your own income.

Do I have to report small amounts paid through an app?

The IRS's gig economy page (US, last reviewed or updated July 9, 2026) says: "You must report income earned from the gig economy on a tax return, even if the income is" missing from any information return form, such as a Form 1099-K.

How can I tell if a passive income program is a scam?

Ask for the seller's disclosure document and compare it with what they tell you. The FTC (US, August 22, 2023) says: "If the seller says anything that contradicts what’s in their disclosure document or earnings claim statement, that’s a sign of a shady operation that you should steer clear of."

Which ideas need the least money to start?

Ideas built on a skill you already have, such as templates, guides or a course, start with your time rather than money. Renting out an asset or investing needs the asset or the capital first.
