The VAT margin scheme exists because taxing second-hand goods, art, antiques, and collectibles on their full selling price would mean charging VAT on value that has already been taxed once. The scheme allows eligible businesses to calculate VAT on the margin between the buying price and the selling price, rather than on the total sale.
That sounds straightforward. In practice, running a margin scheme business involves record-keeping requirements that standard VAT software was never designed to handle. Most accounting platforms treat every sale as a full VAT transaction. Margin scheme sales are fundamentally different, and the software needs to reflect that difference at the transaction level, not as a manual adjustment at period end.
This post covers how the margin scheme works, where compliance breaks down, and what software built for this kind of business actually does.
How the VAT Margin Scheme Works
HMRC operates several margin schemes depending on the type of goods involved. The Global Accounting Scheme and the standard margin scheme are the two most commonly used by dealers in second-hand goods, art, and antiques.
Under the standard margin scheme, VAT is calculated on the profit margin for each individual item. If a dealer buys an antique for £800 and sells it for £1,200, the margin is £400. VAT is calculated on that £400 rather than on the £1,200 selling price. The VAT-inclusive margin is divided by 1.2 to find the VAT element, giving £66.67 in this case.
Under the Global Accounting Scheme, eligible businesses calculate VAT on the total margin across all eligible goods in a VAT period rather than item by item. Total purchases of eligible goods are deducted from total sales of eligible goods, and VAT applies to the resulting figure. This simplifies the calculation for businesses dealing in high volumes of lower-value items.
Both schemes carry specific eligibility rules. The schemes apply only to eligible goods, which generally means second-hand goods, works of art, antiques over 100 years old, and certain collectors’ items. They apply only to goods purchased without VAT, typically from private individuals, unregistered businesses, or other margin scheme dealers. Goods purchased with VAT cannot enter the margin scheme and must be sold under standard VAT rules.
The Record-Keeping Requirements
HMRC’s record-keeping requirements for margin scheme businesses are more detailed than those for standard VAT businesses, and they apply at the individual item level for businesses using the standard scheme.
For each eligible item, the business must maintain a stock book recording the purchase price, the sale price, and the margin. The stock book must be kept even for items where the margin is zero or negative, since negative margins can be offset against positive ones under the Global Accounting Scheme but must still be documented.
Purchase invoices must show that no VAT was charged on the original purchase. If a purchase invoice shows VAT, the item cannot enter the margin scheme. Businesses need a process for identifying and separating standard VAT purchases from margin scheme purchases at the point of acquisition, not retrospectively.
Sales invoices for margin scheme goods must not show the VAT amount separately. Displaying VAT on a margin scheme invoice is a compliance error because it implies the buyer can reclaim input tax they are not entitled to claim.
HMRC can request stock book records during an inspection, and discrepancies between the stock book, purchase invoices, sales records, and VAT returns create significant audit exposure.
Where Compliance Breaks Down
The most common failure point is using standard accounting software for margin scheme transactions without adapting the process to meet the scheme’s requirements.
Standard VAT software calculates output tax on the full selling price of every transaction. A dealer in second-hand goods using standard software and manually adjusting their VAT return at period end is creating a reconciliation gap between what the software records and what was actually declared to HMRC. If that gap is ever examined, explaining it requires documentation that many businesses have not maintained consistently.
The second failure point is mixing eligible and ineligible goods without proper separation. A business that buys some goods with VAT and some without needs a clear process for routing each purchase to the correct treatment. When that process relies on manual identification rather than system-level categorisation, errors accumulate over time.
The third failure point is invoice presentation. Margin scheme sales invoices must not show VAT separately. A business using standard invoicing software that automatically populates a VAT line on every invoice is issuing non-compliant documents for every margin scheme sale. The invoices look professional and the VAT figure appears accurate, but they misrepresent the tax position of the transaction.
The fourth failure point is negative margin handling. Under the Global Accounting Scheme, a period where purchases exceed sales produces a negative margin. That negative margin reduces the VAT due in the current period and, where it exceeds the positive margin, carries forward. Standard VAT software has no concept of a carried-forward negative margin from a scheme calculation.
What Compliant Margin Scheme Software Handles
Software built for margin scheme businesses handles the scheme’s requirements at the transaction level rather than leaving them to manual adjustment.
Item-level stock records are maintained within the platform. Each eligible purchase creates a stock record capturing the acquisition cost, the source, and the VAT status of the purchase. When the item is sold, the system calculates the margin automatically and records it against the stock entry. The stock book HMRC requires is a report generated from data the system already holds, not a separate manual register.
Scheme eligibility is set at the transaction level. When a purchase is entered, the system captures whether it was bought with or without VAT and routes it to the correct treatment accordingly. Standard VAT purchases and margin scheme purchases are separated in the system, not manually identified at period end.
Invoicing follows the correct format for each transaction type. Margin scheme sales generate invoices that do not display VAT separately. Standard VAT sales generate invoices with the VAT amount shown. The format is determined by the transaction type, not by a manual choice the user makes each time.
Global Accounting Scheme calculations aggregate eligible purchases and sales across the period and calculate the net margin automatically. Negative margins are tracked and carried forward correctly without manual intervention.
VAT return preparation draws from the scheme calculations already in the system. The output tax figure on the return reflects the margin scheme methodology, and the supporting records that explain how that figure was reached are in the platform, not in a separate spreadsheet.
Art Dealers and the Artist’s Resale Right
Art dealers operating in the secondary market face an additional compliance layer that margin scheme software needs to accommodate. The Artist’s Resale Right requires dealers selling qualifying works of art above the minimum threshold to collect and remit a royalty to the relevant collecting society.
The royalty is calculated as a percentage of the sale price on a sliding scale, and it applies regardless of whether the sale is made under the margin scheme or standard VAT rules. For dealers with high volumes of secondary market transactions, tracking resale right obligations alongside margin scheme calculations creates a compounded record-keeping requirement.
Software that handles both margin scheme VAT and resale right tracking within the same transaction record removes the reconciliation step between two separate processes. The sale creates both the margin calculation and the resale right obligation in the same entry.
Auction Houses and Multiple Margin Scheme Goods
Auction houses selling second-hand goods, art, and antiques on behalf of vendors operate under different margin scheme rules depending on whether they are selling as principal or as agent.
When an auction house buys goods and resells them, it operates as a principal and the standard margin scheme rules apply. When it sells on behalf of a vendor and takes a commission, the margin scheme calculation is more complex, and the vendor’s status affects the eligibility of the goods.
Software supporting auction house operations needs to handle both scenarios, separating principal transactions from agency transactions and applying the correct VAT treatment to each. Commission income from agency sales is standard rated regardless of the margin scheme status of the underlying goods.
Monesize Core for Margin Scheme Businesses
Monesize Core’s Accounting module supports configurable VAT treatment at the transaction level. For businesses operating the VAT margin scheme, transactions are categorised at the point of entry, stock records are maintained within the platform, and VAT calculations reflect the scheme methodology throughout the period.
The Sales module generates invoices in the correct format for each transaction type, ensuring margin scheme sales do not display VAT separately while standard VAT transactions show the correct VAT amount.
The Activity Logs module maintains a complete record of every transaction, purchase classification, and VAT calculation. For a margin scheme business subject to an HMRC inspection, the stock book, purchase records, and VAT workings are all in one place, retrievable without manual reconstruction.
For businesses using the Global Accounting Scheme, the Accounting module aggregates eligible purchases and sales across the period and calculates the net margin, including carry-forward of negative margin positions where they arise.

The Analytics module gives margin scheme businesses visibility over their VAT position throughout the period. Rather than discovering the VAT liability at return preparation time, finance teams can monitor the margin position as transactions are recorded and plan accordingly.
Choosing Software That Understands the Scheme
The VAT margin scheme is a niche compliance area, and most general accounting software treats it as an edge case to be handled manually. For businesses where margin scheme transactions are the core of the operation, that approach is not viable at scale.
The right software for a margin scheme business is not software with a margin scheme workaround. It is software that treats margin scheme transactions as a native transaction type, maintains the required records automatically, and produces compliant VAT returns without manual adjustment.
If your current software requires you to manually adjust your VAT return to reflect the margin scheme, you are working around a gap that should not exist. That workaround is also the point where your compliance is most exposed.
