Facebook Marketplace & HMRC: Do They Report You?

Last checked against GOV.UK, Facebook's Help Centre and Gumtree's Help Centre: 27 October 2026 · General information, not tax advice

Who has to report sellers to HMRC

Since 1 January 2024, UK rules require digital platform operators to collect details about sellers and report their income to HMRC each January. For goods, GOV.UK says your details won't be reported if you make fewer than 30 sales in a calendar year and receive less than €2,000 (about £1,700) for them (GOV.UK: Selling goods or services on a digital platform). Vinted, eBay, Depop and Etsy all say they follow these rules: see our Vinted and eBay guides.

Facebook Marketplace: what we could and couldn't confirm

You may have read that Meta only reports sales made through Facebook's own checkout. We looked for that on Meta's and HMRC's own pages and couldn't confirm it, so we'd treat it as unverified. Here's what we did find, checking from the UK on 27 October 2026:

• Facebook's Help Centre page on selling with delivery said: "Selling with delivery on Marketplace isn't available in your location at the moment", and pointed to selling locally instead (Facebook Help Centre).
• Facebook's guide to selling an item covers creating a listing and marking it as sold (Facebook Help Centre). We didn't find a Meta help page for UK sellers about HMRC or UK digital sales reporting.

If Facebook ever asks you for your National Insurance number or tax details, check the request inside the Facebook app rather than through a link in a message.

Gumtree: it says it reports

Gumtree's help centre says the UK reporting rules for digital platforms require it to provide sellers' information to HMRC (Gumtree: HMRC reporting for sellers). It says it will contact you automatically if, within a calendar year, you:

• complete 30 sales or more, or
• sell over £1,700.

If you reach that, Gumtree says it will ask individual sellers for their full name, main address and National Insurance number, and share them with HMRC along with the number of transactions and amount paid each quarter (sales minus fees and refunds) and the fees it charged. Gumtree says that if you don't hear from it, you don't need to do anything.

Reported or not, the tax rules are the same

Platform reporting is about what platforms tell HMRC. It doesn't decide whether you owe tax. GOV.UK says being reported "does not automatically mean you owe tax", and HMRC's rules on selling things apply "whether it's online or in person" (HMRC: tax rules for selling things). The same goes the other way: a sale that isn't reported, such as cash on collection, still counts if you're trading.

• Your own unwanted things sold from time to time: you don't usually need to tell HMRC. Valuable items sold for £6,000 or more can be different: see selling personal items.
• Things you buy or make to sell for a profit: likely to be trading. If your gross trading income from all your side hustles is over £1,000 in a tax year (6 April to 5 April), you need to tell HMRC (GOV.UK: trading allowance). Not sure? Read Am I trading? HMRC's badges of trade.

Add your Marketplace sales to the checker

The £1,000 trading allowance covers all your platforms together, including Facebook Marketplace, Gumtree and cash sales. Our free HMRC limit checker has an Other row: put your Marketplace and Gumtree sales there alongside Vinted, eBay and Depop. If you take cash, write each sale down as you go, because there's no platform report to fall back on.

Budget 2026

We checked everything on this page on 27 October 2026. The Budget is on 28 October 2026, and HMRC says full details of its tax announcements will be published that day (GOV.UK: Budget 2026 tax documents). The £1,000 trading allowance is a tax rule that a Budget could change. We'll re-check this page after the Budget.

Quick answers

Does Facebook Marketplace report to HMRC?

We couldn't find a Meta help page that says whether Facebook reports UK Marketplace sellers to HMRC, so we can't confirm it either way. When we checked from the UK on 27 October 2026, Facebook's Help Centre said selling with delivery on Marketplace isn't available in this location. Either way, the tax rules are the same.

Does Gumtree report to HMRC?

Yes. Gumtree's help centre says UK reporting rules require it to provide sellers' information to HMRC, and that it will contact you if you complete 30 or more sales or sell over £1,700 in a calendar year.

Do you pay tax on Facebook Marketplace sales?

It depends what you sell, not where. Selling your own unwanted things is usually not taxed. Buying or making things to sell for profit is likely to be trading, and if your gross trading income from all side hustles is over £1,000 in a tax year, you need to tell HMRC.

Not sure where you stand?

• Use HMRC's free tool: Check if you need to tell HMRC about additional income.
• Read GOV.UK's guide to telling HMRC about income from online platforms.
• Speak to an accountant or tax adviser. If you're on a low income, the charity TaxAid gives free tax help.
