Are You Selling Goods or Services on a Digital Platform? What You Need to Know About Tax in 2025 and ownward
But with this convenience comes a new reality:
HMRC is now closely monitoring these platforms, and automatic reporting is the norm.
If you’ve received a message from HMRC or your platform, don’t panic — but don’t ignore it either. This guide explains exactly when tax applies, when it doesn’t, and how to protect yourself.
Why HMRC Now Sends Messages to Digital Sellers
- Buying and reselling items online or making things to sell (even as a hobby).
- Providing services online, such as tutoring, repairs, food delivery, dog walking, or equipment hire.
- Creating digital content, like podcasts, YouTube videos, or social media influencing.
- Earning income by renting out property or land, like letting a holiday home, running a bed and breakfast, or renting out a parking space on your driveway.
- You made 30 or more sales in the year.
- You earned over €2,000 (about £1,700).
Platforms affected include:
-
Vinted
-
eBay
-
Depop
-
Etsy
-
Airbnb
-
Uber / Deliveroo
-
Fiverr / Freelancer sites
-
Any online marketplace or gig platform
If you hit certain activity thresholds, HMRC will automatically receive your data — even if you made no profit.
This is why many people are suddenly receiving messages they didn’t expect.
Income Tax & Online Platform
When You Do Owe Tax
You may owe tax if your activity becomes trading, meaning you are running a side business.
HMRC looks for indicators like:
-
Buying items specifically to resell
-
Selling items regularly in bulk
-
Making items to sell (handmade goods, artwork, custom clothing)
-
Running an online shop through a platform
-
Reselling trainers, electronics, and vintage clothing
-
Earning more than the £1,000 Trading Allowance
If your profit exceeds £1,000 a year, you may need to file a Self-Assessment tax return.
What About Services on Digital Platforms?
If you’re earning through:
-
Tutoring
-
Deliveries
-
Driving
-
Cleaning
-
Personal training
-
Coaching
-
Freelancing (graphic design, writing, social media)
-
Renting out equipment
-
Renting out property via Airbnb
Then HMRC classifies this as income from services.
You must check whether:
-
You exceed the £1,000 Trading Allowance
-
Your income makes you self-employed
-
You need to register for Class 2 & Class 4 NI
Making Tax Digital
Does HMRC See Everything Now? Yes — Automatically.
In the past, tax was based on honesty and voluntary disclosures.
Today:
Platforms send your data to HMRC every year.
HMRC can now cross-match:
Platform data
Bank account activity
PAYE records
Your UTR (tax ID)
Previous returns
This gives HMRC a clear picture of your digital activity.
What Happens If You Receive an HMRC Nudge Message?
A nudge letter or message means:
HMRC has data suggesting you received income
They want you to review your tax position
They expect a reply or correction if needed
You have three options:
Do nothing —
Only if you sold personal items at a loss and have no trading activity.
Explain your situation —
We can help you craft a clear, correct response.
Register for Self Assessment —
If you crossed the £1,000 profit threshold.
Ignoring HMRC messages can lead to:
Penalties
Backdated tax
Interest
Investigations
Examples: What Counts as Trading?
Example 1 – Decluttering (No Tax)
Sarah’s Situation
Sarah decided to declutter her wardrobe and sold 40 items of second-hand clothing on Vinted over five months. She made £480 in total, with individual items selling for anywhere between £5 and £20.
Key Facts
All items were originally purchased for personal use
Every item was sold for less than its original purchase price
No buying to resell
No profit motive
No regular or structured business pattern
Tax Position
This type of activity is not trading.
HMRC cannot tax Sarah for disposing of personal possessions at a loss — even if she sells large quantities.
Conclusion
→ No tax. No Self Assessment required.
→ Even if Vinted or HMRC contacts her, she needs to explain that the sales were personal, second-hand items.
This example is typical and should reassure most casual sellers.
Example 2 – Side Hustle Reseller (Tax Applies)
James’s Situation
James loves finding vintage jackets at weekend markets. He buys each one for around £30 and resells them on Depop for about £70. Over the year, he sells around 60 jackets, generating roughly £4,200 of sales.
After subtracting his costs:
Purchase costs: 60 × £30 = £1,800
Selling fees, packaging & postage: approx. £1,000
Net profit: £2,400
Key Indicators of Trading
Buying stock specifically to resell
Clear intention to make a profit
Regular and repeated activity
A consistent pattern of listings
Activity resembling a small business
Tax Position
James is running a reselling business, not simply decluttering.
His profit of £2,400 exceeds the £1,000 Trading Allowance, meaning he must:
Register as self-employed
File a Self Assessment tax return
Report trading income and allowable expenses
Conclusion
→ Tax applies. Self-assessment required.
→ James may also need to consider NI contributions and record-keeping.
This is a textbook example of a digital side hustle that HMRC treats as a business.
Example 3 – Etsy Creator (Tax Applies)
Mia’s Situation
Mia creates personalised jewellery in her spare time and sells her pieces through Etsy. Her total annual sales are £6,500. After deducting material costs, Etsy fees, and packaging expenses, her net profit is around £3,200.
Key Facts
She creates products with the intention of selling
Her income is recurring and predictable
She actively markets her items
She reinvests profits into materials and tools
She is clearly operating a business, even if part-time
Tax Position
This is a self-employed creative business.
Mia must:
Register as self-employed
File a Self Assessment
Declare her profit. Keep receipts for materials, tools, and postage
Because her profit exceeds £12,570?
Only the profit above the personal allowance becomes taxable.
Because her profit exceeds £1,000?
Self-assessment is required regardless.
Conclusion
Tax applies. Must declare income as a business.
This example aligns with both HMRC guidance and Etsy’s seller expectations.
Example 4 – “I Didn’t Know I Was Trading” (Grey Area Case)
Amira’s Situation
Amira clears out her wardrobe but also buys trendy items on sale to resell occasionally. Over the year, she sells 25 of her own items and 15 items she bought specifically to resell.
She made:
£600 from personal items (no profit → not taxable)
£1,400 profit from resale items → taxable
HMRC may view part of her activity as trading.
Conclusion
Hybrid cases exist — and they often trigger HMRC letters.
Professional assessment can avoid penalties and incorrect disclosure.
