Accountant for Trading Card Sellers UK — Simplr Accounting

Accountant for
Trading Card Sellers.

Specialist UK accountants for trading card sellers — Pokémon, Yu-Gi-Oh, Magic The Gathering, One Piece, sports cards, sealed products and singles.

Trading card businesses come with a unique set of financial challenges: stock-heavy inventory, sealed vs second hand VAT treatment, grading costs, platform fees across Whatnot, eBay and TikTok Shop, and DAC7 platform reporting already sharing your income data with HMRC. We understand how trading card tax works, the VAT margin scheme rules and exactly what records HMRC expects.

DAC7 reporting

Whatnot, eBay and TikTok Shop now share seller income data directly with HMRC under DAC7 platform reporting rules. If you sell on any of these platforms, HMRC may already have a record of your sales before you file. Undeclared income or inconsistent figures are a red flag. Read our guide on what records HMRC expects or book a call to make sure your returns align.

01 / Why Simplr

We get how card sellers actually operate.

Most accountants see online selling and treat it as simple self-employment. We understand the realities of a stock-heavy TCG business — sealed vs second hand, grading, box breaks, live selling, and the VAT margin scheme rules that most accountants have never heard of.

01

Multi-game specialists

Pokémon, Yu-Gi-Oh, Magic The Gathering, One Piece, sports cards, sealed products and singles — we understand every TCG format and exactly which costs can be deducted from your profits.

02

VAT and the margin scheme

Sealed products are standard-rated for VAT. Second hand singles and graded cards may be eligible for the VAT margin scheme — meaning VAT on your profit, not the full sale price. The rules are strict. Read our full guide on VAT on trading cards.

03

DAC7 platform reporting

Whatnot, eBay and TikTok Shop report seller income to HMRC. Your declared income must match what the platforms report. We make sure your Self Assessment is accurate and consistent before HMRC spots a discrepancy.

04

Record keeping built for sellers

HMRC expects clear records — stock purchases, sales across platforms, grading costs, shipping, refunds and fees. Read our guide on what HMRC expects from trading card sellers and how we help you stay compliant.

05

Platform payout knowledge

Whatnot, eBay, TikTok Shop, Shopify, Discord and card show cash — we understand platform fees, shipping labels, refunds and chargebacks. Your bookkeeping reflects real profit, not just gross sales figures.

06

Fixed monthly fees

No hourly rates, no surprise invoices. A clear monthly fee that covers everything — you know the cost from day one regardless of how many platforms you sell on.

02 / How we help

Everything a card seller needs.

From your first Self Assessment to ongoing bookkeeping, VAT, limited company accounts and tax planning — we handle the financial side so you can focus on sourcing, selling and scaling.

03 / Expenses

Record keeping and HMRC

What records do card sellers actually need?

HMRC expects trading card sellers to keep records of every purchase and sale — purchase price, date, platform, and sale price for each item. For sellers using the VAT margin scheme, the record keeping requirements are even more specific: you need evidence of purchase price for every individual card sold under the scheme. Many sellers grow quickly and find their records can not support a HMRC enquiry. Read our full guide on what HMRC expects from trading card sellers.

VAT margin scheme for second hand cards

Pay VAT on your margin, not the full sale price

The VAT margin scheme may apply to eligible second hand trading cards — singles, slabs and graded cards — where you bought them from a private individual (not a VAT-registered business) and can evidence the purchase price for each item. VAT is then charged only on your profit margin. This can significantly reduce the VAT liability for sellers with high-volume second hand stock. Read our guide on VAT on trading cards for the full detail.

Personal collection vs business stock

Keeping the two clearly separate

Selling cards from your personal collection is generally not trading income — it is a capital disposal, and whether it is taxable depends on the amounts involved. However, if you are buying with the intention to resell, those cards are business stock from the moment of purchase. Mixing the two creates real problems with HMRC and makes the VAT margin scheme records near impossible to maintain correctly. We help you set up clean, defensible records from the start.

04 / Key thresholds

Know where
you stand.

Trading card businesses can scale quickly — particularly sealed product sellers with high throughput, who can hit the VAT threshold faster than expected because registration is triggered by gross turnover, not profit.

£1k
Trading allowance
Once gross trading card income exceeds £1,000 in a tax year, you need to register as self-employed with HMRC and file a Self Assessment return.
£12.5k
Personal allowance (approx.)
You only pay Income Tax on profit above your Personal Allowance. Every allowable expense — stock, fees, grading — reduces your taxable profit and your tax bill.
£50k
MTD Income Tax threshold
If qualifying self-employed income exceeds £50,000, Making Tax Digital applies from April 2026 — digital records and quarterly HMRC updates required.
£90k
VAT registration
Once taxable turnover exceeds £90,000 in a rolling 12-month period, VAT registration is mandatory. For sellers with high throughput, this can arrive sooner than expected. Read our VAT guide.

06 / FAQs

Trading card seller tax questions, straight answers.

Everything you need to know before booking a call.

Do trading card sellers pay tax in the UK?
Yes. If your trading card income goes over £1,000 in a tax year, you will usually need to register for Self Assessment and file a tax return. This applies whether you are full-time or part-time. Read our full guide on whether trading card sellers pay tax in the UK.
What income do I need to declare?
All of it. Sales through marketplaces and live selling platforms, private sales, card shows and any other payments you receive related to selling cards. You report your sales then deduct allowable business expenses to calculate your taxable profit.
What expenses can trading card sellers claim?
Stock purchases, shipping and packaging, platform fees, payment processing fees, grading and authentication costs, storage, card show table fees, business mileage, marketing costs, home office costs, software subscriptions and accountancy fees. Read our guide on what records HMRC expects to make sure you are capturing everything correctly.
Do trading card sellers need to register for VAT?
If your taxable turnover exceeds £90,000 in any 12-month period, you must register for VAT. VAT treatment varies depending on what you sell and how you source your stock — sealed products and second hand cards are treated differently. Read our guide on VAT on trading cards. HMRC's VAT registration guidance covers the general rules.
Can trading card sellers use the VAT margin scheme?
In some cases, yes. The VAT margin scheme may apply to eligible second hand trading cards where you bought them from a private individual (not a VAT-registered business) and can evidence the purchase price for each item. VAT is charged on your profit margin rather than the full sale price. The record keeping requirements are strict. We advise on whether it applies and help you maintain the evidence HMRC requires.
Should I set up a limited company for my card selling business?
It depends on your profits and personal plans. A limited company can be more tax-efficient once profits reach a certain level, but it comes with additional admin and compliance requirements. We run the numbers and advise what makes sense for where you are right now.
Is my information kept private?
Absolutely. We are bound by strict professional confidentiality rules and GDPR. Your financial information is stored securely in encrypted, cloud-based software. We will never share your data with anyone without your explicit permission.
