Shopify VAT Margin Scheme: Why It Does Not Work and What to Do Instead

If you sell second-hand goods through Shopify — whether that is jewellery, antiques, watches, or vintage items — you have probably discovered a frustrating gap: Shopify does not support the VAT Margin Scheme.

There is no setting, no app, and no built-in workaround. Shopify applies standard VAT to every product, and there is no way to tell it to calculate VAT on your profit margin instead.

This guide explains why this is a problem, what dealers currently do to work around it, why those workarounds carry risk, and how to solve it properly.

The Problem: Shopify and the VAT Margin Scheme Are Incompatible

The VAT Margin Scheme allows dealers of eligible second-hand goods to pay VAT only on the profit margin of each sale — the difference between what you paid for an item and what you sold it for — rather than on the full selling price.

For example, if you buy a vintage brooch for £200 and sell it for £350:

• With the margin scheme: VAT is calculated on the £150 margin = £25.00 (£150 ÷ 6)
• Without the margin scheme: VAT is calculated on the full £350 = £58.33 (£350 ÷ 6)

That is a saving of £33.33 on a single item. Across hundreds of transactions a year, the difference is substantial.

The problem is that Shopify has no concept of a “purchase price” for your products. It knows the selling price and the VAT rate — and that is all. It cannot calculate VAT on the margin because it does not know what the margin is.

What Shopify Actually Does

When you create a product in Shopify and assign it a VAT rate:

• Shopify charges the customer the full VAT amount on the selling price
• The order confirmation shows standard VAT
• Shopify’s tax reports calculate VAT on the full selling price
• There is no field for purchase price, no margin calculation, no stock book

This is fine for retailers selling new goods at standard VAT. It is completely inadequate for dealers of second-hand goods who are eligible for — and legally entitled to use — the margin scheme.

The Shopify Community Knows This Is a Problem

Search the Shopify Community forums for “VAT Margin Scheme” and you will find threads going back years from frustrated dealers. The responses from Shopify’s support team are consistent: “Shopify doesn’t support this. You may want to look for a third-party app.”

The difficulty is that no adequate third-party app exists within Shopify’s ecosystem to solve this properly. The margin scheme requires item-level purchase price tracking, per-item margin calculations, and a detailed stock book — none of which Shopify’s product model supports.

What Dealers Currently Do (and Why It Is Risky)

Faced with Shopify’s limitations, dealers have developed various workarounds. All of them introduce risk.

Workaround 1: Set VAT to Zero on Shopify

Some dealers mark all their products as zero-rated or VAT-exempt on Shopify. The customer sees no VAT on their receipt. The dealer then calculates margin scheme VAT manually and accounts for it in their bookkeeping software (Xero, QuickBooks, or FreeAgent).

The risks:

• Your Shopify records show no VAT, but you are collecting and owing VAT on margins — the records do not match
• If HMRC audits your Shopify data, it will appear that you are not charging VAT at all
• There is no digital link between the Shopify sale and the margin calculation
• Under Making Tax Digital, records must be kept digitally with digital links between systems

Workaround 2: Apply Standard VAT and Adjust in Accounting

Other dealers let Shopify charge standard VAT, then create manual journal entries in their accounting software to reverse the standard VAT and replace it with margin scheme VAT.

The risks:

• Customers are overcharged VAT on their receipts (though they cannot reclaim it on second-hand goods, it is still incorrect)
• Every sale requires a manual adjustment — time-consuming and error-prone
• Journal entries are easily forgotten, especially during busy periods
• HMRC can question discrepancies between your point-of-sale records and VAT returns

Workaround 3: Spreadsheets Alongside Shopify

A third approach uses spreadsheets to maintain a parallel stock book. The dealer enters purchase prices, sale prices, and margin calculations in a spreadsheet, while using Shopify purely as a storefront.

The risks:

• Double data entry (Shopify and the spreadsheet) invites errors
• The spreadsheet is not linked to Shopify — data can drift apart
• Spreadsheets are difficult to audit and easy to corrupt
• Under Making Tax Digital, spreadsheets must have digital links to your submission software — most do not

The Common Thread

Every workaround shares the same fundamental problem: you are maintaining two separate systems that do not talk to each other. One system handles selling (Shopify), and a completely different system handles VAT compliance (spreadsheets, accounting software, or paper records). The gap between them is where errors happen.

Why Getting It Wrong Matters

The VAT Margin Scheme is not optional once you have elected to use it. HMRC requires:

• A detailed stock book recording purchase price, sale price, and margin for every eligible item
• Correct VAT calculations on each transaction
• Proper identification of which items qualify for the margin scheme (not all do)
• Digital records under Making Tax Digital

Getting it wrong can result in:

• Penalties for incorrect VAT returns — HMRC charges penalties based on the amount of tax underpaid and whether the error was careless or deliberate
• Interest on underpaid VAT — if your manual calculations understated your VAT liability, you owe interest on the difference
• Loss of margin scheme eligibility — repeated non-compliance can result in HMRC withdrawing your right to use the scheme
• Time-consuming audits — inconsistent records between Shopify and your VAT returns are a red flag for HMRC compliance checks

The irony is that most dealers use the margin scheme because it reduces their VAT bill. But if your record-keeping does not support the calculations, HMRC can assess you at standard rates — wiping out the benefit entirely.

What About Shipping Charges, Card Fees, and Insurance?

A common question from dealers is whether costs like delivery charges, payment processing fees, or insurance affect the margin scheme calculation. The answer depends on who charges what to whom.

Costs That ARE Part of the Margin

According to HMRC’s VAT Notice 718, incidental expenses directly linked to the purchase or sale that you charge to (or are charged by) the other party form part of the purchase or selling price. These include:

• Transport and delivery — If you charge the buyer for shipping, that charge is part of your selling price and included in the margin calculation. Equally, if your supplier charges you for delivery, that is part of your purchase price.
• Packaging — Packaging costs charged to the buyer are part of the selling price; packaging charged by the supplier is part of the purchase price.
• Commission — If you buy at auction, the buyer’s premium you pay is part of your purchase price. If you sell through an auctioneer using the Auctioneers’ Scheme, the seller’s commission reduces the purchase price and the buyer’s premium increases the selling price — both affect the margin calculation. If another dealer charges you commission as part of a purchase, that commission forms part of your purchase price. Some online platforms (such as 1stDibs) act as intermediaries who sit between you and the buyer, arrange shipping, and handle customer service — more like an agent than a simple storefront. In these cases, their sales commission may reduce your selling price for margin scheme purposes. The treatment depends on the specific contractual arrangement, so check with your accountant if you sell through a platform that acts as an intermediary.
• Insurance — If you charge the buyer for insurance as part of the sale, it is included in the selling price. If your supplier charges you insurance as part of the purchase, it is included in the purchase price. However, if the insurance is provided by a third party and the buyer arranges it separately, it is not part of your selling price — account for it outside the margin scheme.

Example: You buy a vintage watch for £400 and the seller charges you £15 for insured postage. Your purchase price is £415. You sell it for £750 and charge the buyer £12 for delivery. Your selling price is £762. The margin is £762 − £415 = £347, and the VAT due is £347 ÷ 6 = £57.83.

Costs That Are NOT Part of the Margin

Business overheads and selling costs cannot be deducted from the margin. The margin scheme taxes the difference between what you paid for an item and what you sold it for — not your overall profit. This means you cannot reduce your margin by subtracting:

• Card processing fees — Stripe, PayPal, or Shopify Payments fees are a cost of doing business, not part of the margin calculation
• Platform fees — Shopify subscription costs, eBay listing fees, or similar charges cannot be deducted from the selling price
• Repair and restoration costs — If you restore an antique before selling it, you cannot add the restoration cost to your purchase price
• Storage, rent, or other overheads — These are general business costs

The distinction between a platform fee and agent’s commission matters here. Shopify charges you a monthly subscription and a payment processing percentage — these are clearly business overheads. But platforms like 1stDibs or auction houses that act as intermediaries between you and the buyer may charge commission that affects the margin calculation because they are functioning as agents rather than simply providing a storefront. If you are unsure how a platform’s fees should be treated, check with your accountant — the answer depends on whether the platform acts as your agent or simply as a service provider.

Why This Catches People Out

Many dealers assume that if Shopify or PayPal takes a 2-3% cut, they can subtract that from the selling price before calculating the margin. You cannot. The selling price is what the customer pays you, before any fees are deducted by payment processors or platforms. Similarly, you cannot add repair costs to inflate your purchase price and reduce the margin.

GemJam handles this correctly: it calculates the margin based on the purchase price you recorded (including any incidental purchase costs) and the selling price, without deducting business overheads or platform fees that are not part of the margin scheme calculation.

Who This Applies To

The VAT Margin Scheme is available to VAT-registered dealers who buy eligible second-hand goods from individuals who are not VAT-registered. Common examples include:

• Jewellery dealers buying from private sellers, estates, and auctions
• Antique dealers sourcing from house clearances and private collections
• Watch dealers purchasing pre-owned timepieces
• Art dealers acquiring works from private owners
• Vintage and retro dealers buying from markets and private sellers

If you buy from VAT-registered businesses, the margin scheme does not apply to those purchases — standard VAT rules apply. GemJam tracks which items qualify and which do not, so you always know which scheme applies to each sale.

Frequently Asked Questions

Does Shopify support the VAT Margin Scheme?

No. Shopify does not have a native VAT Margin Scheme option. It applies standard VAT to all products, which means you cannot use Shopify alone to calculate VAT on the profit margin as required by the margin scheme. You need a separate system to handle margin scheme calculations and record-keeping.

Can I set VAT to zero on Shopify and handle margin scheme VAT separately?

Some dealers set VAT to zero or mark products as VAT-exempt on Shopify, then calculate margin scheme VAT manually in their accounting software. While this avoids charging customers the wrong VAT amount, it creates compliance risks: your Shopify records will not match your VAT returns, there is no audit trail linking sales to margin calculations, and manual processes are prone to errors.

What is the VAT Margin Scheme for second-hand goods?

The VAT Margin Scheme allows dealers of eligible second-hand goods to pay VAT only on their profit margin (the difference between the purchase price and selling price) rather than the full selling price. This can significantly reduce VAT liability. Eligible goods include jewellery, antiques, watches, art, and other unique items bought from non-VAT-registered individuals.

Do I need to keep a stock book for the VAT Margin Scheme?

Yes. HMRC requires dealers using the VAT Margin Scheme to maintain a detailed stock book recording the purchase price, selling price, and margin for every eligible item. Under Making Tax Digital, this stock book must be kept digitally rather than on paper.

Can I sell on Shopify and still use the VAT Margin Scheme?

Yes, but not through Shopify alone. You need a separate inventory management system that handles margin scheme calculations and record-keeping. GemJam does this and syncs your product listings to Shopify, so you get the benefit of selling through your Shopify store while maintaining full margin scheme compliance.

How does GemJam work with Shopify for the margin scheme?

GemJam manages your inventory with built-in VAT Margin Scheme calculations. When you add items to GemJam, it tracks purchase prices, calculates margins on sale, and maintains the digital stock book HMRC requires. GemJam then syncs your product listings — including titles, descriptions, images, and prices — directly to your Shopify store. You sell through Shopify; GemJam handles the VAT.

What happens if I get the VAT Margin Scheme wrong on my Shopify sales?

Getting margin scheme calculations wrong can result in HMRC penalties, interest on underpaid VAT, and potential audits. Common mistakes include applying standard VAT instead of margin scheme VAT, failing to maintain adequate records, and incorrectly claiming items under the margin scheme. The more manual your process, the higher the risk of errors.
