Buying and selling horses sounds simple: buy low, sell higher. In practice, a trading business stands or falls with your eye for a good purchase, your paperwork, and your reputation. Anyone who sells as a professional dealer is also subject to stricter rules than a private individual selling their own horse.
Hobby, Side Income, or Business
The first question is whether you're trading as a private individual or as a business owner. That distinction determines both your tax liability and your legal liability at the point of sale. You're quickly considered a professional seller as soon as you structurally buy horses to resell — even without a registered business.
Characteristics that point toward "business":
- You regularly buy horses with the intention of selling them at a profit.
- You present yourself publicly as a dealer (website, advertisements, stable name).
- The volume and turnover are more than incidental.
Register with the Kamer van Koophandel (KvK, the Dutch Chamber of Commerce) as soon as you trade structurally. For the exact line between a hobby and a business — and the consequences for income tax — the Belastingdienst (the Dutch Tax Administration) or an accountant is the source. Don't underestimate this: being classified as a business owner after the fact while you kept no records is an expensive surprise.
Business Structure and Liability
Most starting dealers begin as a sole proprietorship (eenmanszaak): little paperwork, low start-up costs. The downside is that you're liable with your personal assets. One sale that goes wrong — a horse that turns out to have a hidden defect — can result in a claim that hits you personally.
A BV (the Dutch private limited company) shields your personal assets, but costs more to set up and in annual filings. The choice depends on your volume, the value of the horses, and your risk tolerance. Get advice on this; it's not a decision to make on a gut feeling. The guide Setting up a training or trading stable goes deeper into business structure, permits, and animal welfare.
The Purchase Contract: Your Most Important Document
A verbal agreement is legally valid but impossible to prove if something goes wrong. Put every sale in writing. A usable purchase contract describes at least:
| Item | What you record |
|---|---|
| Parties | Name, address, and whether the buyer is private or a business |
| The horse | Name, chip number, breed, age, sex, studbook papers |
| Price and VAT | Amount, whether VAT is included, payment term |
| Condition and use | What the horse is suitable for (recreation, dressage, jumping up to which level) |
| Vetting | Whether a pre-purchase exam takes place and who pays for it |
| Transfer of risk | From what point the horse is at the buyer's risk |
| Particulars | Known defects, medical history, behavior |
Preferably use a template contract from an industry association or a version drafted by a lawyer, and adapt it for each transaction. Don't invent your own legal wording.
Conformity: Why a Dealer Carries More Risk
If you sell to a consumer (a private buyer), the legal rule applies that the horse must correspond to the agreement — so-called conformity. The animal must have the characteristics the buyer was entitled to expect based on the purchase. If a defect comes to light shortly after the purchase, the buyer can invoke non-conformity.
A few principles in broad outline:
- A dealer is judged more strictly than a private seller. You're assumed to have more expert knowledge.
- What you promise counts. If you sell a horse as "suitable for basic-level sport" or "suitable for riding-school use," it needs to actually be that. Don't promise anything you can't substantiate.
- You must disclose known defects. Concealing something you knew or should have known significantly increases your liability.
- The line between a defect and a normal living-animal risk is often debatable. A horse is not a washing machine; not every issue that surfaces later is a hidden defect.
How non-conformity plays out exactly, and which time limits and burden-of-proof rules apply, depends on the circumstances and current case law. Have an unclear case assessed by a lawyer specialized in equine law. See also Liability around your horse for the broader picture.
The Pre-Purchase Exam as Risk Management
A veterinary pre-purchase exam isn't a legal requirement, but for a dealer it's a form of risk management. An exam records the health status at the time of sale and limits later discussion about when a defect arose.
In practice:
- Agree in advance who pays for the exam and which veterinarian performs it.
- A clinical exam is the basis; X-rays or additional tests belong with more expensive horses or those used in sport.
- Keep the exam report with your sales file.
For the exam process and what X-ray classification grades mean, your veterinarian is the right source.
VAT, Margin, and Record-Keeping
As a business owner, you'll have to deal with VAT. Horse trading has a margin scheme available under certain conditions, where you pay VAT on your profit margin instead of on the full sale price — relevant if you buy in without VAT, for example from private individuals. The rules and conditions are specific; have an accountant confirm whether and how the margin scheme applies to your situation. The guide VAT and tax for the horse business sets out the main points.
Keep watertight records from the very first transaction:
- Purchase invoices or agreements with chip number.
- Costs per horse: boarding, feed, farrier, veterinarian, training, transport.
- Sales contracts and exam reports.
That last item — the costs a horse runs up while it's in the stable — partly determines your actual margin. A horse that stays on the market for three months eats into your paper profit.
Calculating Your Margin
A healthy trading business doesn't earn from one golden deal, but from a responsible margin across your whole stock. Calculate realistically:
- Purchase price is only the start. Add transport, the exam, and a buffer for the unexpected.
- Turnaround time costs money. Roughly a few hundred euros a month for boarding, feed, and care, plus any training costs.
- Not every horse sells for the price you had in mind. Some sell below expectation; plan for that.
- Reputation is your most important asset. One satisfied buyer brings follow-on buyers; one angry buyer with a legitimate complaint costs you far more than the profit on that one transaction.
A rule of thumb dealers use is that the margin must be wide enough to cover the boarding and care costs of the turnaround time and the occasional misstep, and still leave something over. What that margin actually is varies strongly by segment — from a few hundred euros on a recreational horse to a multiple of that on a sport horse with results.
Getting Started in Practice
- Determine your segment: recreational, basic-level sport, or competition horses. It shapes your buying expertise, your risk, and your margin.
- Register with the KvK as soon as you trade structurally, and set up your record-keeping from day one.
- Work with a lawyer-checked purchase contract and adapt it for each transaction.
- Have the margin scheme and your tax liability confirmed by an accountant.
- Build a file per horse — purchase, costs, exam, sale. It's both your evidence and your margin check.
- Don't sell anything you can't stand behind. In the long run, a trustworthy name is your best business model.
Terms such as conformity, pre-purchase exam, and margin scheme are briefly explained in the glossary. For binding details on law and tax, a specialized lawyer and your accountant remain the right source.
