The zone changes. Who now pays the value capture levy?

When meadow or farmland becomes land for building, its value often rises sharply. This gain comes from a decision by the authorities, not your own work. That is why the law asks for a share back.

The canton collects its levy on a new rezoning for building (Einzonung): your land becomes a building zone for the first time¹. The rate is 20 per cent of the gain². Below CHF 30,000 of gain, no levy is charged at all².

Extra building rights or a shift between zones work differently. You may simply build more on land already zoned for building. Here, your municipality decides, not the canton. It sets its own rate and open-space rule. One exception: a public-buildings zone rezoned into another building zone is charged by the canton, as for a new rezoning².

What this means for you: ask your municipal building office whether your plot faces a new rezoning or just extra building rights. That decides which rule applies to you.

For a new rezoning for building, the levy falls due in two cases. Either once building release is granted for your plot. Or at a sale, meaning once ownership changes hands².

Sell before building release, and you, as the seller, owe the levy². There are exceptions for inheritance, an early inheritance payout and a gift. There, the new owners only pay once they themselves build or sell².

Extra building rights or a rezoning follow a different rule. A sale alone does not trigger it³. Only building by the new owner triggers the levy. Sell your plot, and the duty simply passes to the buyer²³.

What this means for you: we work for you as the owner, not for the buyer. That is why we say plainly when a levy is passing to the buyer. It belongs in every sale contract and every serious offer.

Yes. The value capture levy later reduces your gain for property gains tax (Grundstückgewinnsteuer), the tax on the profit from a sale⁴. You pay this tax when you sell land for building, on the profit you make. This applies whether a new rezoning or extra building rights triggered your levy.

The tax act counts the levy you have paid as an expense⁴. Expenses are deducted from your gain before the tax is calculated. The federal Spatial Planning Act confirms this deduction too¹. The rule applies in every canton, not only in Zurich.

The order matters here: only a levy you have already paid counts for you. If the duty passes to the buyer later, the buyer claims that deduction instead. You, as the seller, no longer benefit from it.

What this means for you: keep a written record of every levy you have paid or still owe. Your tax adviser needs this figure for the exact calculation. The calculator for the Canton of Zurich shows the matching tax.

The gain in value is a simple difference. What would your plot be worth without the zoning change, and what is it worth with it? That difference is the gain. This applies equally to a new rezoning and to extra building rights³.

For a consistent calculation, the cantonal building authority (Baudirektion) uses so-called land price models³. These are formulas based on sales that have actually been notarised. This saves costly individual valuations. They are reviewed roughly every four years³.

At the public planning notice (Planauflage), you receive your forecast gain in value and may comment on it.³ After it is finalised, the authority checks of its own accord whether an individual valuation is needed. Within ten days of that notice, you may request one yourself – at your own cost, without choosing the valuer.³

What this means for you: read your municipality's notice carefully and within the deadline. A building lease as an alternative to a sale follows its own calculation.
