Do You Pay Tax on Affiliate Income? What Lesso Affiliates Should Know

The first commission that lands in your Stripe account raises a question nobody warns you about: is this actual income, the kind you have to tell a tax authority about, or is it closer to a gift card balance you can quietly spend? The honest answer is that it's real income from the moment it's paid, in the US, the UK, and every EU member state, regardless of how small the amount is or whether you've registered anything. This post covers the general mechanics of how that works and how Lesso's own payout system fits into it. It's not personal tax advice, and nothing here should be treated as a substitute for an accountant who knows your specific situation and jurisdiction.

Is affiliate income actually taxable

Yes. Commission you earn through an affiliate or referral programme is taxable income the moment it's paid to you, in the same way a freelance invoice or a self-employed sale is. There's no separate, lighter category for "affiliate income" or "referral income" in US, UK, or EU tax law. It gets treated as ordinary income from self-employment or a trade, reported alongside anything else you earn outside a standard payroll job.

This holds whether the payment is described as a "commission," a "bonus," or a "referral reward," and whether it arrives monthly or as a single lump sum. The label on the payment doesn't change its tax treatment; what changes it is that money changed hands for something you did.

Do you need a business or to register as self-employed to receive it

No, not to start. You can share a Lesso referral link, earn commission on it, and watch that commission accrue without registering a company, applying for an EIN, or becoming a sole trader first. Lesso's affiliate agreement states this directly: sharing your referral link and earning commission doesn't require approval of any kind. What does require a step is turning accrued commission into money in your bank account, and that step is about identity verification through Stripe, not business registration with a tax authority. Those are two separate gates, and mixing them up is the single most common source of confusion for new affiliates.

In the United States, you don't need an LLC, a corporation, or an EIN to receive affiliate income. Your Social Security number works as your taxpayer ID, and by default you're a sole proprietor the moment you start earning, reporting the income and any related expenses on Schedule C of your Form 1040. The IRS generally expects you to file if your net self-employment earnings reach $400 in a year, and a business paying you $2,000 or more in a calendar year must send you a Form 1099-NEC, a threshold that rose from $600 starting with 2026 payments under recent tax legislation, per the IRS's own instructions for Form 1099-NEC (checked July 2026). Not getting a 1099 for a smaller amount doesn't mean it's not reportable; the form is a paperwork trigger for the payer, not the line where your obligation to report begins. Whether an LLC is worth the state filing fee on top of any of this is a liability-protection and bookkeeping question, not a prerequisite for getting paid.

In the United Kingdom, you can earn up to £1,000 in gross trading income in a tax year under HMRC's trading allowance before you're generally required to tell HMRC about it at all, as confirmed on GOV.UK's guidance on tax-free allowances for trading income (checked July 2026). Cross that threshold and HMRC expects you to register for Self Assessment and file a return, but "register for Self Assessment" is a form you submit as an individual; it isn't the same as setting up a limited company, and most affiliates never need one.

In the EU, there's no single EU-wide tax authority or registration process. Each member state sets its own rules for what counts as self-employed or freelance income, at what point you must register, and what that registration involves, so what applies to you depends entirely on which country you're tax resident in. A useful shortcut: search "[your country] self-employed tax threshold" or ask an accountant licensed in your country, rather than assuming a rule you read for another EU state applies to you.

Does this only apply to affiliate income, or any side hustle?

HMRC applies the same £1,000 trading allowance and Self Assessment threshold to any side income, not only affiliate commission. The same figures cover money from selling on Vinted above the trading allowance, freelance design work, or weekend tutoring. If your actual question is "do I need to tell HMRC about a side hustle" rather than specifically about affiliate income, the answer worked through above still applies: no, not until your total trading income from that activity crosses £1,000 in a tax year, and yes, register for Self Assessment once it does. Categorising and reporting the income correctly once you're above that threshold depends on the specific activity, which is where an accountant familiar with your full mix of income earns their fee.

What it takes to actually get paid, versus what it takes to owe tax

These are not the same checklist, and Lesso's own structure makes the split visible. Payouts are available to affiliates in the United States, the United Kingdom, and the European Union; Stripe verifies your identity and bank details directly as part of onboarding your Stripe Connect account, and Lesso never sees or stores that banking information. That verification exists so Stripe and the platform know who they're paying, which is a fraud and compliance requirement, not a tax registration. Owing tax on the commission starts the moment it's paid to you, independent of whether you've completed Stripe's onboarding yet; commission earned before you have a payout-ready account still accrues and is still your income once it transfers, it just sits until you're set up to receive it.

Treat this table as the shape of the mechanism, not a substitute for checking the current rule in your own country. Thresholds and forms change; an accountant or your national tax authority's own site has the current figure.

Is this a hobby or a business, and does it matter

It matters more in the US than anywhere else, because the IRS distinguishes hobby income from business income and taxes them differently: business income lets you deduct related expenses (hosting, tools, a portion of your internet bill) against the commission you earned, while hobby income generally doesn't get the same deductions. The distinction turns on whether you're running this with the regularity and intent of a business, consistent effort, a profit motive, treating losses and reinvestment the way a business would, rather than posting a link once and forgetting about it. Most people writing reviews or recommendations regularly enough to earn meaningful affiliate income already clear that bar without trying to.

The UK and most EU countries don't split hobby from business the same way; if the income crosses the relevant threshold, it's reportable regardless of how seriously you consider the activity. Either way, "I didn't think of this as a real business" isn't a defence against a filing requirement in any of the three regions covered here.

How does Lesso report affiliate income

Lesso pays affiliate commission through Stripe Connect, the same payout infrastructure used for creator payouts. For US-based payees, information return filing on payments made through a platform like this is generally handled at the payment-processor level rather than by the platform manually issuing paper forms, which is worth knowing so a form (or the absence of one) doesn't come as a surprise. The specific form and threshold that apply to your account can change as US tax rules do, so check your Stripe dashboard directly, or ask Stripe support, for what applies to your account rather than relying on a general description here.

What Lesso commits to contractually is narrower and more stable: per section 7 of the affiliate agreement, you are solely responsible for declaring and paying tax on your affiliate earnings, and Lesso recommends consulting an accountant. That's the same position Lesso takes with course creators on their own revenue share. Neither Lesso nor Stripe files your personal tax return for you or tells your tax authority how to classify the income; that responsibility, and the judgement calls that come with it, stay with you.

Is affiliate income different from a salary

Functionally, yes, and the difference is what catches new affiliates out. A salary or PAYE job withholds tax before the money reaches you, so what lands in your account is already net. Affiliate commission through Stripe arrives gross, with nothing withheld, whether that's a US 1099-style payment, UK self-employment income, or a payment to an EU sole trader. Nobody sends a portion to a tax authority on your behalf as it's paid.

The practical consequence is that the full commission amount showing in your Stripe balance isn't the amount you get to keep. Setting money aside as it comes in, rather than working out what you owe once a year, is the difference between a manageable tax bill and an unpleasant one, and it's one of the first things an accountant will tell a new affiliate to do regardless of country.

What to actually do next

If you're earning enough that this stopped being a rounding error, the reliable move is the boring one: keep a simple record of what you've earned and when, and take it to an accountant who works with self-employed or freelance clients in your country before you file anything. None of the general mechanics above replace someone looking at your specific numbers, your other income, and your country's current rules.
