Making Tax Digital for Online Sellers: Etsy, eBay, Amazon & Vinted (2026 Guide)

Does MTD Apply to Online Sellers?

Short answer: yes, if your gross self-employment income exceeds £50,000 per year.

Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) rolls out on 6 April 2026 for the first wave. It applies to all self-employed individuals and landlords — and that includes online sellers.

If you sell products on Etsy, eBay, Amazon, Vinted, Depop, or any other online marketplace as a self-employed trader, you're caught by exactly the same rules as any other sole trader. HMRC doesn't distinguish between someone selling handmade candles on Etsy and someone running a plumbing business. Self-employment is self-employment.

The key dates:

That second wave in April 2027 is the big one for online sellers. Many Etsy and eBay sellers with gross sales between £30,000 and £50,000 will be drawn in. And since HMRC uses gross income (not profit), the threshold catches more people than you might expect.

The £50,000 Threshold: Gross Income, Not Profit

This catches a lot of online sellers off guard. The £50,000 threshold is based on gross income — your total sales before deducting any expenses.

Here's why that matters:

This is particularly harsh for online sellers because platforms like Etsy, eBay and Amazon charge significant fees (often 12-20% of your sale price). Your gross income looks much higher than what actually lands in your bank account.

What counts toward the £50,000:

• All sales revenue from all platforms (Etsy + eBay + Amazon + your own website)
• Any other self-employment income (freelancing, consulting, etc.)
• Property rental income (if applicable)

What doesn't count:

• Employment income (PAYE salary)
• Interest on savings
• Dividends
• Pension income
• Selling personal items (not trading)

Platform-by-Platform Breakdown

Etsy Sellers

If you run an Etsy shop as a business (not just selling the odd personal item), you're self-employed. Your Etsy sales count toward the MTD threshold.

Etsy sellers face a particular challenge with record-keeping because Etsy's payment system bundles multiple orders into periodic payouts. You need to track individual transactions, not just bank deposits. Most MTD software can import Etsy CSV statements, which makes this manageable.

Key Etsy expenses to track: listing fees (£0.16 per item), transaction fees (6.5%), payment processing fees (4% + £0.20), advertising fees (if using Etsy Ads), shipping labels, materials, packaging.

eBay Sellers

eBay selling falls into two categories, and MTD only applies to one:

• Trading (MTD applies): Buying stock to resell, selling handmade items, running an eBay business. This is self-employment.
• Personal sales (MTD doesn't apply): Clearing out your attic, selling items you bought for personal use at a loss. This isn't self-employment.

The line between these can be blurry. HMRC uses "badges of trade" to determine if you're trading: frequency of sales, volume, whether you're buying with the intention of reselling, whether you've modified items before selling. If you're doing it regularly and making a profit, you're probably trading.

Key eBay expenses to track: final value fees (up to 12.8% + £0.30), promoted listings fees, eBay shop subscription, packaging, postage, stock purchases.

Amazon / Amazon FBA Sellers

Amazon sellers, especially those using Fulfilment by Amazon (FBA), tend to have higher gross incomes and are more likely to hit the £50,000 threshold. If you're running an Amazon FBA business, MTD almost certainly applies to you.

FBA sellers have additional complexity: stock sent to Amazon warehouses, storage fees, long-term storage penalties, removal orders, reimbursements for lost/damaged stock. Your MTD software needs to handle all of this.

Key Amazon expenses to track: referral fees (8-15%), FBA fulfilment fees, monthly storage fees, long-term storage fees, advertising (PPC), stock purchases, shipping to Amazon warehouses, returns processing.

Vinted / Depop Sellers

These platforms sit in a grey area. Most Vinted and Depop users are selling personal items — clearing out their wardrobe. That's not self-employment and MTD doesn't apply.

But if you're buying clothes specifically to resell (thrifting for profit), running a vintage clothing business, or consistently selling at a profit, you're probably self-employed. And if your gross income from this activity (plus any other self-employment) exceeds £50,000, MTD applies.

In practice, very few Vinted/Depop sellers hit the £50,000 threshold from clothing resale alone. But if you also sell on other platforms or have other self-employment income, the combined total might push you over.

DAC7: HMRC Already Knows What You Sell

Since 1 January 2024, online platforms must report your selling activity to HMRC under the EU-derived Digital Platform Reporting rules (commonly called DAC7). This applies if you:

• Made 30 or more sales in a calendar year, OR
• Earned €2,000 or more (roughly £1,700) in a calendar year

Platforms report your name, address, date of birth, National Insurance number (if provided), total sales, number of transactions, and any fees deducted.

What this means for you: HMRC can now cross-reference what platforms report against your Self Assessment return (or lack thereof). If you're selling £50,000+ on Etsy and not filing a tax return, HMRC knows. And with MTD, they'll expect quarterly digital updates on top of that.

DAC7 and MTD are separate requirements, but they work together. DAC7 tells HMRC what you sold. MTD requires you to tell HMRC what you earned and spent — quarterly, in digital format.

If you haven't been declaring your online selling income, now is the time to get compliant. HMRC's voluntary disclosure process is much more favourable than being caught.

What Actually Changes Under MTD

If you're already filing Self Assessment as a self-employed online seller, MTD doesn't change what you report. It changes how and how often.

The quarterly updates are summaries, not full returns. You report total income and total expenses for the quarter. No receipts, no individual transactions — just the totals. The detail lives in your digital records, which HMRC can request if they open an enquiry.

For a detailed breakdown of what MTD means in practice, read our complete MTD guide.

Quarterly Submissions: What to Report

Under MTD, the tax year is divided into four quarters plus a final declaration:

Each quarterly update includes:

• Total income for the quarter (all platform sales combined)
• Total expenses for the quarter (broken down by category)

For online sellers, "income" means your gross sales — not your platform payouts. If you sold £15,000 of products on Etsy in Q1, but Etsy kept £2,250 in fees and only paid you £12,750, your income is still £15,000. The £2,250 in fees is an expense.

Best MTD Software for Online Sellers

You need software that can:

1. Import transactions from your selling platforms (Etsy, eBay, Amazon, etc.)
2. Keep digital records in the format HMRC requires
3. Submit quarterly updates to HMRC via the MTD API

Here are the best options for online sellers specifically:

Best Overall: FreeAgent (£7-14/month)

UK-focused, clean interface, handles Etsy and eBay imports well. Free if you bank with NatWest or RBS. Strong expense tracking and receipt capture. MTD-compatible.

Best for Multi-Platform Sellers: Xero (£8-15/month)

More powerful integrations — connects to Etsy, eBay, Amazon, Shopify and more via apps like A2X or Link My Books. Better for sellers doing £100k+ across multiple platforms.

Best for Amazon FBA: Xero + A2X

A2X is specifically built for Amazon and Shopify sellers. It breaks down Amazon's complex settlement reports into clean accounting entries. Essential for FBA sellers with significant volume.

Best Budget Option: Bridging Software (£0-5/month)

If you already track everything in a spreadsheet, bridging software connects your spreadsheet to HMRC's MTD API. You keep your existing system, just submit digitally. Options include 123Sheets, SimpleTax, and HMRC's own free tool.

Read our full MTD bridging software guide for details.

Best Free Option: HMRC's Free Software

HMRC is releasing free MTD software. It's basic — no bank feeds, no platform imports, no receipt scanning. But it's free and it meets the legal requirement. If you're a small seller close to the threshold, this might be enough.

For a detailed comparison, read our free vs paid MTD software guide.

Digital Record-Keeping for Online Sellers

Under MTD, your records must be kept digitally. This doesn't mean you can't use spreadsheets — it means you can't keep paper-only records.

What you must record for each transaction:

• Date of the transaction
• Amount
• Category (income type or expense type)

For online sellers, this means tracking:

Income Records

• Individual sale amounts (or platform settlement summaries)
• Which platform each sale was made on
• Refunds and returns (deducted from income)
• Any other self-employment income

Expense Records

• Platform fees (listing fees, transaction fees, payment processing)
• Cost of goods sold (materials, stock purchases)
• Shipping and postage
• Packaging materials
• Software subscriptions (accounting, design, listing tools)
• Advertising spend (Etsy Ads, eBay Promoted Listings, Amazon PPC)
• Home office costs (if you work from home)
• Equipment (camera, printer, computer — capital allowances)
• Storage costs (if renting storage space for stock)

Pro tip: Download your platform CSV statements monthly. Etsy, eBay and Amazon all provide downloadable transaction histories. Import these into your accounting software rather than entering transactions manually — it's faster and less error-prone.

Expenses Online Sellers Can Claim

Many online sellers under-claim expenses, paying more tax than necessary. Here's a comprehensive list of what you can claim:

Direct Costs

• Stock/materials: Everything you buy to make or resell products
• Platform fees: Etsy listing fees, eBay final value fees, Amazon referral fees, FBA fees
• Payment processing: Etsy Payments fees, PayPal fees, Stripe fees
• Shipping: Postage, courier charges, Royal Mail labels
• Packaging: Boxes, tissue paper, labels, tape, branded packaging

Operational Costs

• Software: Accounting software, listing tools, photo editing, design tools
• Advertising: Etsy Ads, eBay Promoted Listings, social media ads, Google Ads
• Photography: Camera equipment, lighting, backdrops (capital allowances for equipment over £1,000)
• Internet: Proportion used for business
• Phone: Proportion used for business
• Insurance: Product liability, public liability
• Training: Courses related to your business (photography, marketing, etc.)

Home Office

If you work from home (and most online sellers do), you can claim either:

• Simplified expenses: £10/month (25-50 hours), £18/month (51-100 hours), £26/month (101+ hours) — no receipts needed
• Actual costs: Proportion of rent/mortgage interest, council tax, electricity, heating, water based on the room you use and hours worked

Use our profit margin calculator to see how expenses affect your actual margins.

Penalties and the Grace Period

Good news first: HMRC confirmed a 12-month penalty grace period for the 2026/27 tax year.

This means:

• No penalty points for late quarterly submissions during your first year
• You won't get the £200 fixed penalty that normally applies after accumulating points
• The grace period is automatic — you don't need to apply for it

But there are limits to the grace period:

• Late payment penalties still apply from day one. Interest starts immediately on unpaid tax. A 2% charge kicks in at day 16, and another 2% at day 31.
• The final declaration (31 January 2028) is not covered. Miss your annual finalisation and you'll face penalties.
• The grace period ends after year one. From 2027/28 onwards, full penalty points apply.

After the grace period, the penalty system works on points:

• 1 point for each late quarterly submission
• At 4 points (for quarterly submissions): automatic £200 penalty
• Points reset after 12 months of compliance

For the full breakdown, read our MTD penalty grace period guide and use our MTD penalty calculator to see potential costs.

Your 5-Week Action Plan (Before 6 April 2026)

You have roughly 5 weeks before MTD starts. Here's what to do:

Week 1 (1-7 March): Check Your Numbers

• Download your 2024/25 platform statements (Etsy, eBay, Amazon)
• Add up your total gross income across all platforms
• If it's over £50,000, MTD applies to you from 6 April
• If it's between £30,000 and £50,000, you have until April 2027 — but start preparing now

Week 2 (8-14 March): Choose Your Software

• Sign up for a free trial of FreeAgent, Xero, or your preferred option
• Check it can import from your selling platforms
• If you want to keep your spreadsheet, research bridging software instead

Week 3 (15-21 March): Set Up Digital Records

• Connect your bank account to your accounting software
• Import your platform data for the current tax year (2025/26)
• Set up expense categories that match your business
• Backfill any missing transactions

Week 4 (22-28 March): Sign Up for MTD

• Register for MTD for Income Tax via your HMRC Business Tax Account
• Authorise your chosen software to submit to HMRC
• Do a test submission if your software allows it

Week 5 (29 March - 5 April): Final Checks

• Ensure your digital records are up to date through 5 April
• Set calendar reminders for Q1 deadline (5 August 2026)
• Download the mobile app for your accounting software (receipt capture on the go)

Common Mistakes Online Sellers Make

1. Using Platform Payouts as Income

Your income is your gross sales, not what the platform pays you. If you sold £1,000 of products on Etsy but only received £850 after fees, your income is £1,000 and your expenses include £150 in fees. Getting this wrong means your quarterly updates will be inaccurate.

2. Forgetting Multi-Platform Income

The £50,000 threshold applies to your total self-employment income. If you sell £30,000 on Etsy and £25,000 on eBay, your combined £55,000 puts you above the threshold. Many sellers only count their main platform.

3. Not Separating Personal and Business Sales

If you sell both personal items and trading stock on eBay, you need to separate them. Personal sales aren't self-employment income. Keep them on separate accounts if possible, or at least track which is which.

4. Ignoring Stock/Inventory

Under accrual accounting, stock you've bought but not sold isn't an expense yet. Most small online sellers use cash basis accounting (which is simpler), but make sure your software is set to the right method. Under cash basis, you claim the expense when you pay for the stock, regardless of when you sell it.

5. Missing the Threshold Because of a Good Month

One strong holiday season could push your annual gross income over £50,000. The threshold is based on the tax year — if you're close to £50,000, monitor your sales monthly. It's better to be prepared and not need MTD than to be caught out.

6. Not Claiming Legitimate Expenses

Many online sellers forget to claim home office costs, phone, internet, training, and software subscriptions. These add up. Under-claiming expenses means paying more tax than you owe.

Frequently Asked Questions

Does MTD apply to Etsy sellers?

Yes, if your gross self-employment income from Etsy (and any other self-employment or property income) exceeds £50,000 per year. From 6 April 2026, you must keep digital records and submit quarterly updates to HMRC using MTD-compatible software.

Does MTD apply to eBay sellers in the UK?

Yes, if you're trading (buying to resell or selling handmade items) and your gross income exceeds £50,000. If you're just selling personal items, that's not self-employment and MTD doesn't apply.

What's the difference between gross income and profit for MTD?

HMRC uses gross income (total sales before deducting expenses) to determine the threshold. So if you sell £55,000 on Etsy but your profit is only £20,000, MTD still applies.

Do I need MTD software if I sell on multiple platforms?

Yes, and you'll need software that handles income from all platforms. Most MTD-compatible software can import from multiple sources.

What about the digital platform reporting rules (DAC7)?

Since January 2024, platforms report seller data to HMRC if you make 30+ sales or earn €2,000+. This is separate from MTD but means HMRC already knows your activity.

Is there a penalty grace period for online sellers?

Yes — 12 months. No penalty points for late quarterly submissions during 2026/27. But late payment penalties apply from day one.

I sell on Vinted — does MTD apply to me?

Only if you're trading (buying to resell at profit). Selling personal items isn't self-employment. HMRC looks at frequency, volume, and profit motive.

Do Amazon FBA sellers need to comply with MTD?

Yes, if gross income exceeds £50,000. FBA sellers need software that can track Amazon payouts, fees, shipping, and inventory.
