How Old to Sell Online? The 2026 Age Rules, Site by Site

For years, the age question on the internet was a formality. Type a birthday, click continue, nobody looked twice.

That era is ending. Google announced this week that it is rolling out its age-assurance technology to Android developers worldwide by the end of the year, following similar verification pushes across app stores and social platforms. Sites that once shrugged at birthdays are starting to actually check. For a family with a young entrepreneur, that changes the calculus. A shop built on a fudged birthday is now a shop that can vanish overnight, sometimes with money still in it.

Parents tend to discover this at the worst moment. The kid spends a summer building an audience and a review history, the platform runs a verification sweep, and the account freezes with two weeks of payouts inside. Appeals go slowly when the original sin is a false birthdate, because the platform's records now say the account never should have existed. The good news: there are fully legitimate paths for kids to sell, and they are not complicated. You just need to know the real rules before the first listing goes up, not after.

Three reasons, and none of them is meanness.

First, contracts. Selling on a platform means agreeing to a legal contract, and minors generally cannot be held to one. Platforms set age floors to protect themselves.

Second, privacy law. U.S. federal rules under COPPA put strict limits on collecting personal data from children under 13, so most services simply exclude that group.

Third, money. Getting paid requires payment processing, and processors run identity checks that minors cannot pass. Follow the money and you will find the reason almost every marketplace wants an adult's name on the account.

Etsy is one of the friendlier big platforms for young makers, and its rules are specific. A seller must be 18 to have their own shop. Kids between 13 and 17 can sell, but only through a shop their parent or legal guardian owns and supervises.

Supervised means more than nearby. The account must carry the parent's name, the parent's financial details, and the parent listed as the shop owner in the About section. Under-13s cannot use Etsy at all, even with permission. When the teen turns 18, Etsy support can help transfer the shop into their name, with reviews and history intact. That transfer is worth planning for, because a shop with three years of five-star reviews is a real asset on day one of adulthood.

eBay sets its minimum at 18, no youth tier. The workable arrangement is the same parent-owned model: you open the account, and your teen runs the operation inside it. They can photograph items, write listings, answer buyers, and pack boxes. You own the login, the payouts, and the legal responsibility, including any taxes.

Most other big venues rhyme with this. Facebook Marketplace requires an adult account. Local selling apps generally do too. Before your kid touches any platform, spend five minutes reading its actual terms page rather than a forum post from 2019, because these policies have tightened and keep tightening as verification tech spreads.

The model works when the division of labor is explicit. Write it down like a tiny partnership agreement.

The kid owns the product, the pricing, the listing photos, the customer messages (with you reading over their shoulder for anything odd), and the fulfillment. You own the account, the payment flow, tax records, and the final call on anything involving a stranger, a refund, or an address.

One more rule that saves grief later: the money is the kid's, minus agreed costs, and it moves to their savings on a schedule. When the account is in a parent's name it is easy for earnings to blur into the family budget. Do not let them. Ownership of the profit is what makes the whole exercise feel real.

Even a kid's business earns real income, and payment platforms report business earnings to the IRS above certain thresholds. Because the account carries your name, those reports land on you.

No need for panic, just for records. Keep a simple ledger from the first sale: date, item, sale price, fees, shipping, supply costs. A photo folder of receipts is enough. Small ventures often owe little or nothing once costs are counted, but only records can prove it. There is a bonus here that has nothing to do with the IRS: a kid who watches fees and shipping eat a $20 sale learns margin faster than any worksheet could teach it.

Make the ledger the kid's job, with a weekly five-minute review together. Ten sales in, ask them the two questions every business owner eventually faces: which product actually makes money, and which one just feels good to sell? Plenty of adults have never run that math on their own ventures. A 14-year-old who has done it owns a skill that compounds for decades.

If the account rules feel heavy for a first venture, skip platforms entirely. In-person selling has no terms of service.

Children's business fairs run all summer and fall across the country, and the Acton Children's Business Fair network hosts events built specifically for ages 6 to 14, where kids handle real customers and real cash. This July alone, fairs from Texas to Washington put dozens of kid-run booths in front of paying strangers. Farmers markets often rent youth tables cheaply. Neighborhood sales, school craft fairs, and community events round out the list. Cash businesses teach the same core loop, make something, price it, sell it, count profit, with zero age verification. Many families do a season of fairs first, then graduate to a supervised online shop once the product proves itself.

Whichever venue you choose, make the kid write the plan first. One page, four questions: what am I selling, who buys it, what does each unit cost me, what do I charge?

This is the step that separates a business from an expensive hobby. It can live in a notebook, a shared doc, or a planning tool like Foundra that gives young founders a structured template for exactly these questions. The plan also becomes your decision tool as the parent: if the numbers on the page do not work at a lemonade-stand scale, they will not work with Etsy fees stacked on top. Approve the plan, then open the shop, in that order.

• Age verification is tightening across the internet, with Google pushing age-assurance tech to Android developers worldwide this year. Fudged birthdays are now a business risk.

• Etsy allows 13- to 17-year-olds only inside a parent-owned, parent-supervised shop. eBay and most marketplaces require an adult account outright.

• The parent-owned model works when roles and profit ownership are written down.

• Keep sale-by-sale records from day one, since platform earnings reports arrive in the parent's name.

• Children's business fairs and markets offer a no-platform starting line for ages 6 to 14.

Can my 12-year-old have an Etsy shop if I run it? No. Etsy's floor is 13 even with full parental supervision, because federal privacy rules treat under-13s differently. Until then, in-person venues are the way.

Is letting my kid use my account against the rules? On Etsy, the supervised structure is officially supported for 13 and up. On eBay and most others, an adult-owned account with the teen helping is the accepted arrangement. What breaks the rules is a minor claiming to be an adult.

Who pays taxes on my kid's sales? Earnings reported under your name land on your return by default. Keep clean records of income and costs, and talk to a tax preparer once sales pass hobby scale. This article is general information, not tax advice.

What about a kid selling digital products or coding apps? Same account rules apply, and app stores add their own developer age requirements, usually 18 with parent-managed paths varying by platform. Check the specific store's current terms.

When should the business move into the kid's own name? At 18, transfer accounts formally rather than starting over. Etsy supports handing a supervised shop to the now-adult seller, reviews included.
