Do I have to tell HMRC if I sell my old clothes on Vinted?

If you're selling your own personal possessions — clothes, books, kitchen equipment, jewellery, phones, anything that belonged to you for your own use — you almost certainly do not have to pay Income Tax, no matter how many items you sell. HMRC's own example on gov.uk says: 'clearing out your attic and selling unwanted items... it's unlikely that you'll need to tell us about this income or pay any tax, no matter how many items you sell.' The exception is if a single item (or a matching set) sells for more than £6,000, which can trigger Capital Gains Tax.

What is the £1,000 trading allowance?

The trading allowance is a tax exemption of up to £1,000 per tax year (6 April to 5 April) for individuals with trading income. If your total gross trading income is £1,000 or less, you generally do not need to tell HMRC or register for Self-Assessment. If your gross trading income is more than £1,000, you can either use the £1,000 allowance as a flat deduction, or claim your actual expenses — whichever gives you the lower taxable profit. The allowance has existed since 6 April 2017.

When do I have to register for Self-Assessment as a UK reseller?

If your gross trading income for a tax year is more than £1,000, you must register for Self-Assessment by 5 October in the following tax year. 'Gross' means the total you received before deducting stock cost, postage, platform fees or any other expenses. You register online at gov.uk/log-in-file-self-assessment-tax-return/register-if-youre-self-employed. Even if you can later knock your taxable profit below £1,000 using the allowance or expenses, the registration obligation is triggered by gross income.

Do online marketplaces report my sales to HMRC?

Yes — from January 2024, digital platforms operating in the UK (eBay, Vinted, Depop, Etsy, Airbnb and others) are required to collect information about their sellers and report certain activity to HMRC. HMRC's guidance on income from online platforms was first published 28 November 2024 and last updated 13 February 2025. The reporting applies regardless of whether you count as trading — it's the platforms' obligation, not yours — but it means HMRC can cross-check your tax return against what the platforms say you received.

Can I deduct stock cost, postage and packaging from my reselling income?

Yes — if your gross trading income is above £1,000 and you're registered for Self-Assessment, you can deduct legitimate business expenses (stock cost, postage, packaging, platform fees, a portion of transport, etc.) instead of using the £1,000 trading allowance. You choose whichever gives you the lower taxable profit. You cannot use both. You must keep records of income and expenses either way — HMRC requires this even under 'full relief' when your gross is under £1,000.

Is the £1,000 trading allowance based on profit or total sales?

Total sales (gross). HMRC defines gross income as 'the total amount you would put on your tax return before any allowances or expenses are taken off.' This is the single most misunderstood part of the rule. If you sold £1,500 worth of goods across the year but after stock, postage and packaging your actual profit was only £300, you have still crossed the £1,000 threshold on gross and must register for Self-Assessment. Profit only matters for calculating how much tax you owe, not for whether you have to register.

What records do I need to keep for HMRC as a reseller?

HMRC requires records of income even if you don't have to report it. For resellers that usually means: sale price and date, buyer location (for platform fees), stock cost and where you bought it, transport costs, packaging, postage, payment processing fees, and any unsold stock at year-end. A tracking app or spreadsheet with CSV export is usually sufficient. Keep records for at least 5 years after the 31 January Self-Assessment deadline of the relevant tax year.

When Does HMRC Say You're a Business? The £1,000 Trading Allowance for UK Resellers (2026)

Q: At what point do I count as a reseller rather than someone selling unwanted stuff?

HMRC says you're probably trading if you sell goods that you bought intending to sell for a profit, or items you made (including hobby items). The key signals are intent to profit, regularity, and buying-to-sell. HMRC's gov.uk example states: 'After earning some money from selling unwanted clothes, you start buying items from car boot sales and charity shops. You sell these items through online marketplaces, with the intention of selling them for more money than you paid for them. This is something you do regularly. You have received income through online platforms from selling goods and you may need to tell us about this income.'

Q: If I have no other job, do I actually owe tax on my reselling profit?

Possibly not. Registering for Self-Assessment and owing Income Tax are two different things. If your gross trading income is over £1,000 you must register, but you only pay Income Tax on your taxable profit, and only on the portion above the Personal Allowance. The standard Personal Allowance for 2026-27 is £12,570. So if reselling is your only income and your taxable profit (after the £1,000 allowance or actual expenses) is below £12,570, you still have to file a return, but your tax bill is £0. National Insurance has its own thresholds and is separate from Income Tax.

15 April 2026 Guides 9 min read

Every reseller subreddit in the UK has the same recurring post: "Do I need to tell HMRC?" The answers are always confident and usually wrong in some way — either cartoonishly paranoid ("they’ll audit you for selling a jumper") or dangerously relaxed ("under a grand doesn’t count, ignore it").

HMRC’s actual guidance is surprisingly readable. It was first published on 28 November 2024 and last updated on 13 February 2025. This post walks through what it says, with the specific rules that apply to people buying from charity shops, car boots and estate sales and re-selling on eBay, Vinted, Depop, Facebook Marketplace and Etsy.

Important: this is an explainer of HMRC’s own published guidance. It’s not tax advice. If you’re close to a threshold, or your situation involves multiple income types, talk to an accountant.

The three categories HMRC cares about

HMRC splits online income into a few categories. For resellers the two that matter are:

Selling personal possessions — items that belonged to you for your own use (clothes, ornaments, kitchen equipment, jewellery, computers, phones).
Selling goods — goods you bought intending to sell for a profit, or items you made.

They’re treated completely differently. Knowing which bucket a sale falls into is the single most important thing on this page.

Selling personal possessions — usually no tax, no matter how much

If you’re clearing out your own wardrobe, attic, kitchen or storage and selling things you previously owned for your own use, HMRC’s guidance is explicit:

“You’re clearing out your attic and decide to sell your unwanted items using online marketplaces. None of the items you sell are worth more than £6,000. It’s unlikely that you’ll need to tell us about this income or pay any tax, no matter how many items you sell.”

— HMRC, Check if you need to tell HMRC about your income from online platforms

The one exception: if you sell a single item or a matching set for more than £6,000, you may need to pay Capital Gains Tax. HMRC gives the examples of chess pieces, a set of books by the same author, and matching vases — any of which, if sold as a set above £6,000, counts as a single disposal.

So for the typical Vinted user clearing out their own wardrobe? You’re almost certainly in the clear, even if you sell hundreds of items over a year.

Selling goods — where resellers live

The moment you buy something with the intention of reselling it for a profit, HMRC considers that trading. The same is true if you make items for a hobby and sell them.

This is the line most resellers cross without noticing. HMRC’s own example:

“After earning some money from selling unwanted clothes, you start buying items from car boot sales and charity shops. You sell these items through online marketplaces, with the intention of selling them for more money than you paid for them. This is something you do regularly. You have received income through online platforms from selling goods and you may need to tell us about this income.”

— HMRC, gov.uk

The three signals HMRC looks for:

Intent to profit — you bought the item specifically to sell it for more
Regularity — this is something you do often, not a one-off
Buying to sell — as opposed to disposing of things you already owned for your own use

If two or three of those apply to you, you’re in the trading category. What happens next depends on how much you made.

The £1,000 trading allowance

This is the number everyone half-remembers. Here’s exactly what it does.

The trading allowance is a tax exemption of up to £1,000 per tax year (6 April to 5 April the following year). It has existed since 6 April 2017. There are two modes:

Full relief — if your gross trading income for the tax year is £1,000 or less, you do not need to tell HMRC or register for Self-Assessment. You still have to keep records of the income.
Partial relief — if your gross trading income is more than £1,000, you can deduct the £1,000 allowance as a flat reduction instead of claiming your actual expenses. You pick whichever is better for you. You can’t use both.

Gross means the total amount you received, before stock cost, postage, packaging or platform fees are deducted. If you bought ten charity-shop jumpers for £3 each, sold all ten for £20 each, and your postage totalled £30 — your gross income is £200, not your profit.

Straight from HMRC: “Gross income means the total amount you would put on your tax return before any allowances or expenses are taken off.”

— HMRC, Tax-free allowances on property and trading income

This matters because the £1,000 trigger is about money in, not money kept. You can sell £1,500 of stock across the year, net only £300 after costs, and you still have to register for Self-Assessment. Gross = sales. Profit comes later.

When you must register for Self-Assessment

If your gross trading income crosses £1,000 in a tax year, you must register for Self-Assessment by 5 October of the following tax year. HMRC guidance:

“If your gross income for a tax year is more than £1,000, you must register for Self Assessment by 5 October in the following tax year.”

— HMRC, Tax-free allowances on property and trading income

The registration deadline is triggered by gross income, not profit. This is the part that catches people out: even if you end up with barely any taxable profit (because expenses ate it all), the fact that you took more than £1,000 in gross revenue means you still have to register.

Registration is online at gov.uk.

Registering isn’t the same as paying tax: the Personal Allowance

This is the part that gets lost in every “HMRC is coming for resellers” post. Having to register is not the same as having to pay.

The UK has a Personal Allowance — the amount of income you can earn each tax year before Income Tax kicks in at all. For the 2026–27 tax year (6 April 2026 to 5 April 2027), the standard Personal Allowance is £12,570. Bands above it:

Up to £12,570 — 0% (Personal Allowance)
£12,571 to £50,270 — 20% (Basic rate)
£50,271 to £125,140 — 40% (Higher rate)
Over £125,140 — 45% (Additional rate)

The Personal Allowance is shared across all your income — job, reselling, pension, savings interest. If you already use it up at a day job, every pound of reselling profit above £1,000 is taxed at your marginal rate. But if reselling is your only income, you get the full allowance against it.

Practical example. You’re a stay-at-home parent with no other UK income. Across the tax year you gross £6,000 on Vinted and eBay reselling items you sourced from car boots. After the £1,000 trading allowance, your taxable profit is £5,000. That’s well under the £12,570 Personal Allowance — your Income Tax bill is £0. You still have to register for Self-Assessment and file the return, because gross is over £1,000. But you owe nothing.

Two things worth knowing:

The Personal Allowance tapers away if your total taxable income is above £100,000 (£1 removed for every £2 over). It hits zero at £125,140. Not a typical reseller problem, but mentioned for completeness.
National Insurance is separate from Income Tax and has its own thresholds. Class 2 and Class 4 NICs can kick in on self-employed profits even if you owe no Income Tax. Check gov.uk’s NI pages or ask an accountant if your trading profit is above a few thousand pounds.

The takeaway: registering for Self-Assessment sounds scary but in many hobby-level reseller cases the actual Income Tax bill is zero. What you’re doing is putting the numbers on paper so HMRC can see you’re below the line — which is the whole reason the platform-reporting rules (next section) exist.

Platforms are now sharing data with HMRC

From January 2024, UK-operating digital platforms (including eBay, Vinted, Depop, Etsy, Airbnb and others) are required to collect seller information and report certain activity to HMRC. This is an obligation on the platforms, not on you — but the practical effect is that HMRC can now cross-reference what you declare against what the platforms say you received.

If you’ve been flipping on Vinted for three years without registering for Self-Assessment while earning £5,000 a year gross, that information may now be sitting in HMRC’s system. The safest move is to register, use the allowance or claim expenses, and report honestly.

Worked examples (in reseller language)

Example 1: Clearing your own wardrobe

You sell 80 items from your own wardrobe on Vinted across the year, totalling £1,400. None of the items cost more than £6,000.

Category: personal possessions
Tax owed: none
Register for Self-Assessment: no

Even though you crossed £1,000, the £1,000 trading allowance isn’t the relevant rule here — you weren’t trading. You were selling your own stuff.

Example 2: Occasional charity-shop flipping

You pick up 20 items at charity shops and car boots across the year, spend £60 on stock, sell them for £480 gross.

Category: trading (you bought to resell)
Gross income: £480 — under £1,000
Tax owed: none
Register for Self-Assessment: no (full relief applies)
Keep records anyway: yes

Example 3: Serious side hustle

You flip regularly all year. Gross sales £3,200. You spent £400 on stock, £180 on postage and packaging, £100 on petrol/parking to car boots, £0 on platform fees (eBay private seller, Vinted).

Category: trading
Gross income: £3,200 — over £1,000, register for Self-Assessment
Option A — claim £1,000 trading allowance: taxable profit = £3,200 − £1,000 = £2,200
Option B — claim actual expenses (£680): taxable profit = £3,200 − £680 = £2,520
Better choice: the £1,000 allowance

This is exactly why records matter. Without knowing your actual expenses you can’t pick the better option — and in most cases the allowance is better for small, low-expense traders, while actual expenses are better once your costs climb above £1,000.

Example 4: Reselling as your only income

Stay-at-home parent, no day job, no other UK income. Gross sales on Vinted and eBay across the year: £6,000. Stock £900, postage £400, packaging £80, transport to car boots £120. Total expenses: £1,500.

Category: trading
Gross income: £6,000 — over £1,000, register for Self-Assessment
Taxable profit (actual expenses): £6,000 − £1,500 = £4,500
Personal Allowance available against it: £12,570
Income Tax owed: £0
You still have to file a Self-Assessment return. Check separately whether Class 2 / Class 4 National Insurance applies.

Example 5: Full-time reseller

Gross sales £18,000. Stock £5,500. Postage £1,800. Packaging £400. Transport £900. Platform fees (eBay business seller) £2,300. Total expenses £10,900.

Category: trading, business-scale
Register for Self-Assessment: yes (obviously)
Claim actual expenses: taxable profit = £18,000 − £10,900 = £7,100
The £1,000 allowance would leave you with £17,000 taxable — far worse

What records do you actually need?

HMRC’s rule is simple: keep records. Even if you’re under £1,000 and on full relief, you still have to be able to prove it if asked.

For a reseller that means, per item:

Date and where you bought it (“charity shop in Wandsworth, 12 April” is fine)
Cost price
Date sold
Sale price and which platform
Postage paid (if not covered by buyer)
Packaging cost (bubble wrap, mailer)
Platform fees deducted

Plus shared costs allocated across trips:

Petrol / parking / train to sourcing locations
Entry fees at car boots
Returns and lost postage

HMRC wants to see records kept for at least 5 years after the 31 January Self-Assessment deadline of the tax year they relate to.

FAQ

Do I need to tell HMRC if I sell my old clothes on Vinted?

Almost certainly no. Selling personal possessions (your own clothes, household items, etc.) that never cost more than £6,000 individually is not taxable income. HMRC’s own guidance says this applies “no matter how many items you sell.”

What counts as “trading” in HMRC’s eyes?

Buying goods with the intention of selling them for profit, or making items (including hobby items) and selling them. The key signals are intent to profit, regularity, and buying-to-sell.

When do I have to register for Self-Assessment?

If your gross trading income for a tax year is more than £1,000, you must register by 5 October of the following tax year. Gross means before any expenses are deducted.

If I have no other job, do I actually owe tax on my reselling profit?

Possibly not. Registering and owing tax are different things. If your only UK income is reselling and your taxable profit (after the £1,000 allowance or your actual expenses) is below the £12,570 Personal Allowance, your Income Tax bill is £0. You still have to file a return if your gross went over £1,000, but there’s nothing to pay. National Insurance is separate and has its own thresholds.

Is the £1,000 allowance based on profit or total sales?

Total sales (gross). HMRC’s own words: “Gross income means the total amount you would put on your tax return before any allowances or expenses are taken off.” Sell £1,500 with only £300 net profit? You still crossed £1,000 and must register.

Can I use the £1,000 allowance AND deduct my actual expenses?

No. You pick one: either the flat £1,000 allowance or your actual business expenses. Usually small traders benefit from the allowance; larger operations benefit from expenses. A good tracker or spreadsheet lets you compare both before choosing.

Do eBay, Vinted and Depop report my sales to HMRC?

Yes. Since January 2024, UK-operating digital platforms have to report seller information to HMRC. This is an obligation on the platform, not on you — but it means HMRC can cross-check your tax return against what the platforms say you received.

What happens if I didn’t register when I should have?

Talk to an accountant or HMRC directly. HMRC has voluntary disclosure routes and tends to be more lenient with people who come forward than with people who are caught. Penalties for unprompted disclosure are usually much lower than penalties after an investigation.

What’s the best way to keep HMRC-ready records as a UK reseller?

A tracking app that captures per-item cost, sale price, platform, dates, and allocated transport/entry fees, and exports to CSV. FlipperHelper does this and is free on the App Store. A spreadsheet works too — the point is that you can show HMRC a per-item ledger with dates and costs if they ask.
