Trader (dealer, developer, builder)

A property trader is someone who acquires property with the intention of resale. In tax terms, this sits alongside dealer, developer and builder classifications, each of which has its own land-sale provisions.

Why classification matters

A trader's property is trading stock, not a capital asset. Profits are taxable as income, and there is no bright-line safe harbour — the gain is taxable regardless of how long the property is held.

The classification attaches to the person, not just the transaction. Once you are trading, subsequent purchases can be caught, and associated persons can be caught too.

What indicates trading

• A pattern of buying and selling
• Short holding periods
• Renovating and reselling repeatedly
• How the purchase was financed and described
• Statements of intent — including in finance applications, to agents, or in writing

Common misunderstanding

Intent is assessed at the time of acquisition and evidenced by conduct. IRD does not simply accept your account. Emails, texts, loan applications, business plans and social media have all been used as evidence.

One flip does not necessarily make you a trader, but it may be taxable anyway under the intention test. These are separate questions.

"I changed my mind" is a difficult argument. It can succeed on the facts, but the burden is on you and the documentary trail usually decides it.

Trading and investing can coexist but should be structured separately, with advice, so the trading activity does not contaminate the long-term portfolio.
