Personal Goods as Opening Stock When You Start Reselling

You cleared out your wardrobe, the bits sold quickly, so now you buy to sell as well. The moment you cross from "clearing out" to "reselling", a question lands on your desk: what about all the clothes you already owned and have now started listing for profit? Do they count? At what value? And does any of this even need to go on a tax return?

This is one of the fiddliest corners of starting a small resale business, and people get it wrong in both directions. Some ignore their own goods entirely. Others try to deduct what they originally paid years ago at full retail. Neither is right.

This guide explains how HMRC treats personal goods that you bring into a new resale trade as opening stock, why the value is market value (not what you paid), and how it flows through to your profit and your tax. It is written for people selling on platforms like Vinted, but the rules apply to any reseller. If you sell on Vinted specifically, our guide for Vinted sellers walks through the wider picture.

All figures are for the 2025/26 tax year unless stated.

Do your own clothes count as opening stock?

If you have genuinely started trading, then yes, the personal items you bring into that trade and sell for profit are treated as stock of the business, and they come in at their market value on the day you introduce them.

That is the short answer. The longer answer turns on two separate questions that people tend to blur together: first, are you actually trading at all, and second, if you are, how do those personal items get valued and taxed. We will take them in that order, because the first one decides whether the rest even applies to you.

When does selling your own things become a trade?

Selling your own unwanted possessions is not trading. If you list last season's coat and a pair of boots you never wear, that is not a business, it is a clear-out, and there is no income tax to worry about.

It becomes a trade when the activity takes on the character of a business. HMRC decides this using the "badges of trade", a set of factors drawn from decided tax cases. No single badge is conclusive on its own. HMRC looks at the overall picture (see HMRC's Business Income Manual at BIM20205). The factors that matter most for resellers are:

• Profit-seeking motive. Are you buying or sourcing items mainly to sell them on at a profit?
• Frequency and number of transactions. A few one-off sales is not a trade. Repeated, systematic, organised selling points strongly towards one.
• Nature of the goods. Items bought for resale, rather than for your own use and enjoyment, look like stock.
• The way the sale is organised. Sourcing, photographing, listing and shipping at volume looks like a business.

The crossover point in practice is usually when you start buying (or making) things specifically to sell. The moment your motive shifts from "I no longer want this" to "I bought this to flip", you are likely trading. From that point, the clothes you already owned and decide to fold into the same selling activity become part of the trade too.

How do you value personal goods brought into the business?

When you take an asset you already own personally and bring it into your trade as stock, tax law treats it as if your business bought it from you at its market value on the day it goes in. Not what you originally paid. Not retail. Market value, meaning what the item would realistically fetch in its current condition.

This rule comes from a long-standing principle established in the case Sharkey v Wernher, now written into statute at sections 172A to 172F of the Income Tax (Trading and Other Income) Act 2005. HMRC sets it out in its Business Income Manual at BIM33630, which says that where a trader "transfers to his business stock which he owns in some other capacity than that of proprietor of that business, the transfer should be dealt with for taxation purposes as if it were a sale or purchase at market value."

So your opening stock figure for these items is the total of their realistic resale values at the date you start trading. That total becomes the cost of that stock in your accounts. When you sell the items, the difference between what they sell for and that opening value is your taxable profit on them.

For a reseller, market value of a used garment is essentially what a willing buyer would pay for it second-hand right now, the sort of price comparable items list and sell for on the platform you use. Keep it sensible and evidenced. An inflated valuation reduces your profit on paper but will not survive an enquiry.

Why market value and not what you paid?

It feels counter-intuitive, so it is worth understanding why the rule works this way.

When you bought a £90 dress for yourself two years ago, that was personal spending. It was never a business cost, because at the time there was no business. You cannot retrospectively turn old personal purchases into tax-deductible stock at their original price, because that is not what they cost the business.

What the business effectively "pays" for the dress is its value on the day it enters the trade. If that dress is now worth £20 second-hand, your business takes it in at £20. Sell it for £25 and you have made £5 of taxable profit on it. Sell it for £18 and you have a small loss on that item. The original £90 is irrelevant to the trade, because it was your money as a private individual, not the business's.

This also stops the opposite abuse, where someone tries to claim a big "loss" by valuing old goods at full retail and then selling them for far less. Market value at the date of introduction keeps the figure honest.

Illustrative example: turning a wardrobe into opening stock

Illustrative example. Priya decides her occasional Vinted selling has become a proper side business. From spring 2025 she starts buying job lots of clothing to resell, and she folds 60 items from her own wardrobe into the same trade.

She values those 60 personal items at their realistic second-hand prices, evidenced by comparable listings. They come to £540 in total. That is her opening stock.

Over the 2025/26 tax year:

Her taxable profit is worked out as sales, less cost of goods sold, less other expenses:

£2,400 − £960 − £210 = £1,230 profit.

Because that £1,230 sits well inside her remaining personal allowance for the year (the tax-free amount most people can earn, £12,570 for 2025/26), and her profit is below the £12,570 Class 4 National Insurance lower profits limit, Priya may have no actual tax to pay on it. But the profit still has to be reported on her Self Assessment return once her trading income passes the reporting threshold (covered below). The arithmetic, and whether the trading allowance would beat claiming expenses, is the next thing to check.

A quick calculator can help you sanity-check the position. Our self-employed tax calculator estimates the Income Tax and National Insurance on a profit figure like this.

Trading allowance or actual expenses, which is better?

Every individual gets a £1,000 trading allowance per tax year. It is an alternative to deducting your real costs, and HMRC's guidance is explicit that you cannot do both: "You cannot deduct any other expenses or allowances if you claim the allowances" (see tax-free allowances on property and trading income).

So you pick whichever leaves you better off:

• Claim the £1,000 allowance if your total costs (including the market value of your opening stock that you sold) are less than £1,000. You then pay tax on gross income minus £1,000.
• Claim actual expenses if your real costs are higher than £1,000, which they usually are once you factor in opening stock, purchases, postage and fees.

In Priya's example, her gross income is £2,400. Using the allowance would leave £2,400 − £1,000 = £1,400 taxable. Claiming actual costs gives a £1,230 profit. Actual expenses win here, by £170 of taxable profit, precisely because her opening stock and other costs comfortably exceed £1,000.

There is one trap worth flagging. If you claim the £1,000 trading allowance, you forfeit the value of your opening stock as a deduction. For most genuine resellers that makes the allowance the worse choice, because the whole point of valuing your own goods as stock is to get relief for that value. The allowance suits very small, low-cost sellers, not someone building a real resale business.

If your gross trading income for the year is more than £1,000, you must register for Self Assessment by 5 October following the end of that tax year, and report the trade.

Will Vinted report you to HMRC?

Possibly, and this is the change that has made so many sellers suddenly anxious. Under the UK rules for digital platforms, marketplaces such as Vinted, eBay and Etsy collect information about their sellers and report it to HMRC once a year.

A platform does not have to report you if, in the calendar year, you both make fewer than 30 sales of goods and receive less than 2,000 euros (about £1,700) for those sales. You have to be under both limits to fall outside reporting (see HMRC's guidance on selling goods or services on a digital platform).

Two things to keep clear in your head:

• Being reported is not the same as owing tax. The platform passing your data to HMRC does not decide your tax. Whether you owe anything depends on whether you are trading and what your profit is.
• Not being reported does not mean tax-free. If you are genuinely trading and your gross income tops £1,000 in a tax year, you must tell HMRC, whether or not the platform reported you. HMRC's check if you need to tell HMRC about income from online platforms is the plain-English starting point.

The practical upshot: keep your own records straight, because they are what your tax is actually based on, and they should reconcile to whatever the platform reports.

Is there any capital gains tax on selling old clothes?

For the genuine clear-out items you sell before you start trading, almost never.

Selling a single personal possession only comes onto the Capital Gains Tax radar if the proceeds exceed £6,000, and even then most clothing is exempt as a "wasting asset". A wasting asset is one with a predictable life of 50 years or less, and HMRC's helpsheet HS293 for 2025/26 confirms that "any gain or loss on the disposal of a personal possession which is a wasting asset is exempt from Capital Gains Tax". Everyday clothes fall squarely in that bracket.

The important distinction is this: once an item is part of your trade as stock, it is no longer a personal possession. Profit on selling trading stock is taxed as trading income, not as a capital gain. Capital Gains Tax and the £6,000 chattels rule are about the genuine personal sales, not your resale business.

What records should you keep?

Good records here are not optional, they are the difference between a clean Self Assessment and a painful enquiry. For your opening stock specifically, keep:

• A dated list of every personal item you brought into the trade, with the market value you gave each one.
• Evidence for those values, such as screenshots of comparable sold listings around the date you started trading.
• The date you consider the trade to have started. This anchors your opening stock and your reporting obligations.

Then run normal bookkeeping for the trade: all sales, all purchases of stock, postage, packaging, platform and payment fees, and your closing stock figure at the year end. Profit is sales, minus cost of goods sold, minus other allowable expenses. Solid records make that calculation simple and defensible.

If the bookkeeping is starting to feel like more than the selling, that is usually the point to get help. Zmartly handles the records and the return for online sellers, so the numbers are right and you can get back to sourcing stock.
