The most important things first
In a property sale in the canton of St.Gallen, the real estate capital gains tax is often a decisive cost. By keeping receipts meticulously, checking co-ownership or a timely transfer, and for owner-occupied homes observing the reinvestment deadline, you can legally influence the tax burden. It is also important that a later tax deferral continues to burden the replacement property.
From our practice at Prefera Immobilien AG, it repeatedly shows that the biggest savings are not achieved at the sale itself but in the preparation beforehand. By thinking about the tax consequences early, you can retain significantly more room for maneuver at the later sale.
Why is the real estate capital gains tax so important during the sale?
When selling a property in the region, the real estate capital gains tax is particularly relevant because current record prices often create high profits. However, the total gain does not stay entirely with the seller; when disposals come from private assets, it is subject to the property gains tax. That is exactly why it pays to review the tax consequences early with expert guidance.
What receipts are needed for the taxable gain?
A taxable gain exists when the sale proceeds are higher than the acquisition costs. These acquisition costs include the purchase price, value-enhancing investments and ancillary costs such as transfer taxes, land registry fees or the sales commission of a professional broker. For the cantonal tax office to accept these items, they must be clearly and fully documented with invoices.
Ordinary maintenance costs are not included; they are considered for income tax. This is where many practical mistakes occur, because maintenance and value-enhancing investments are often mixed up. If you collect the documents cleanly over the entire holding period, you avoid later discussions with the tax office.
Don’t hunt receipts only at the sale
Invoices, receipts and contracts should be archived during the entire ownership period. What is missing at the sale can often no longer be documented afterward and ultimately increases the taxable gain.
Why can co-ownership be tax advantageous?
With multiple co-owners, the total tax amount is lower than with a sole owner because the progression is divided. The gain is calculated per capita, and only then is the tax determined. For owners, this can make a noticeable difference depending on the situation.

In our daily business, we see that even the ownership structure can make a difference of several thousand francs. In the cited example, the tax drops from CHF 24,816 to CHF 18,116 when two people share equally. A transfer can thus be worthwhile, but must be planned in good time.
Which acquisition price variant is the better solution?
If a property has been owned for more than twenty years, two variants can be examined for the acquisition price. Either the effective purchase price at the time of acquisition applies, or the market value valid twenty years ago. Depending on holding period and timing of value-enhancing investments, this can lead to a significantly different tax amount.
What is often overlooked: A newer official appraisal can be tax-friendlier if it shows a higher market value. Therefore, waiting for an updated appraisal and potentially delaying the sale to reduce the taxable gain can be a deliberate strategy.
| Variant | When relevant | Possible effect |
|---|---|---|
| Actual acquisition price | At the original purchase | May result in a higher taxable gain |
| Market value twenty years ago | With longer ownership | May reduce the taxable gain if the appraisal is higher |
When is a tax deferral possible?
If owner-occupied property is sold and the proceeds are reinvested within a maximum of three years into another self-occupied replacement property, a tax deferral may be possible depending on the amount reinvested. If the replacement investment is lower than the acquisition costs of the sold property, deferral does not apply. The deferral is therefore not a tax exemption but is carried over to the new property.
This is exactly where a common misconception lies: Deferral is not elimination. If you don’t consider the mechanism, you may make a more expensive decision at the later sale because the deferred gain is taxed again.
