My Partner Buys the Stock and I Sell It on Vinted. Whose Income Is It?

This question comes up more often than you'd think, and it's rarely framed as a tax question when it first gets asked. It usually starts as a practical division of labour. One of you is better at spotting a bargain in a charity shop. The other is better at writing listings and dealing with buyers. You split the work, the money goes into one account, and neither of you has thought about it as anything other than a shared hobby that occasionally pays for itself.

Then someone mentions HMRC and platform reporting, and the question suddenly matters: whose income actually is this?

Why the Account Name Doesn't Settle It

It would be convenient if the answer were simply "whoever's Vinted account it is." It isn't.

HMRC looks at who is actually conducting the trade: making the decisions, putting in the effort, and bearing the risk if items don't sell. A platform account is just the mechanism for listing and receiving payment. It doesn't determine who the trading income legally belongs to.

This matters because plenty of couples run their selling exactly the way you've described, one person sourcing, the other selling, both genuinely contributing meaningful time and decision-making. If that's a fair description of your situation, you're not really one person trading with help. You're two people trading together, which in HMRC's eyes can look like a partnership, even an entirely informal one that's never been registered as such.

The Three Most Common Scenarios

Scenario one: it's genuinely a joint effort. You both source, you both make decisions about pricing and what to buy, and you both put in regular time. This is the scenario most likely to be treated as a partnership. Each partner reports their share of the profit on their own Self Assessment return, and each partner has their own £1,000 trading allowance to set against their share.

Scenario two: one of you is just helping occasionally. Your partner picks things up for you when they're at a charity shop anyway, or helps you carry boxes to the post office. The trading decisions, the profit motive, and the bulk of the work are yours. This looks much more like your sole trading activity with occasional help, not a partnership. The income is yours to declare.

Scenario three: you've never really thought about it and you're somewhere in between. This is the most common scenario and the hardest to give a definitive answer for. The honest approach is to look at where the decisions actually get made and where the time actually goes, then be consistent about how you treat it going forward.

Why This Isn't Just a Technicality

Splitting the income matters for two practical reasons beyond just getting the paperwork right.

Each individual has their own £1,000 trading allowance. If the activity genuinely belongs to both of you, splitting the profit means you're effectively getting two allowances against the same trading activity rather than one. A couple making £1,800 profit between them who correctly treat it as a 50/50 partnership each have £900 of profit, both comfortably under the personal trading allowance. The same £1,800 attributed entirely to one person exceeds the allowance and triggers a registration requirement.

It also matters for income tax if one of you is a basic rate taxpayer and the other is a higher rate taxpayer through employment. Profit correctly allocated to the lower earner is taxed at a lower rate than the same profit incorrectly bundled into the higher earner's return. This isn't a loophole. It's simply taxing income where it actually arose, which is exactly what HMRC expects.

What to Actually Do

If you've read through the three scenarios above and you genuinely think you're running this together, the practical fix is straightforward. Agree a fair split based on the actual contribution each of you makes, whether that's 50/50 or something else that reflects reality. Both of you register for Self Assessment if your individual share of gross income from the activity exceeds £1,000 in a tax year. Each of you reports your own share.

If it's clearly your activity with occasional help, keep treating it as yours. The help your partner gives doesn't change who the trading income belongs to. There's no obligation to involve them in the tax position just because they've occasionally carried a box to the post office.

If you're not sure which category you're in, the safest approach is to be consistent. Pick the description that most honestly reflects how the work actually happens, apply it for the whole tax year, and don't switch back and forth depending on which arrangement produces a lower tax bill in any given year. HMRC is far more concerned with consistency and honesty than with which exact split you chose.

Our trading allowance guide covers how the £1,000 threshold works for an individual, and our guide to whether your selling counts as trading has an interactive quiz that helps you work out where your activity sits on the personal-disposal-to-trading spectrum, which is worth doing for each of you separately if you're genuinely splitting the work.

The UK Online Seller Tax Template works for a single trader's gross income, expenses and profit calculation. If you and your partner are running this as a genuine partnership, each of you would use your own copy of the template based on your individual share of the income and expenses.
