Property gains tax sounds like something for large houses with gardens. Yet it applies just the same to the condominium on the third floor. In Bassersdorf the median comparison shows this clearly.
In 2007 a flat here cost a median CHF 499,000, a house CHF 710,000. In 2025 the figures are CHF 1,327,500 and CHF 1,560,000. In the median comparison, the flat therefore pays CHF 179,648 in property gains tax and the house CHF 184,464. Almost the same amount, for a property that costs CHF 232,500 less at the median.
Why are flat and house so close when it comes to tax?
Worked example
Worked example, Bassersdorf: house, 18 years of ownership
Assumption: bought in 2007 and sold in 2025, each at the Bassersdorf median for single-family houses, without investments or costs. For a flat, the same calculation gives a gain of CHF 828,500 and tax of CHF 179,648.
- Sale price (median 2025, provisional)
- CHF 1,560,000
- Purchase price (median 2007)
- – CHF 710,000
- Property gain
- CHF 850,000
- Tax per tariff, before reduction
- CHF 329,400
- Reduction for 18 full years: 44%
- – CHF 144,936
- Property gains tax
- CHF 184,464
- Remaining after tax, before mortgage
- CHF 1,375,536
Why does a flat in Bassersdorf pay almost as much tax as a house?
Because it made almost the same gain. In 2007 the median flat cost CHF 499,000, the median house CHF 710,000.2 By 2025 the gap had barely grown. The gain on the flat is CHF 828,500, on the house CHF 850,000.
The tax follows the gain, not the type of property.1 So the flat incurs CHF 179,648 and the house CHF 184,464. Since 2015 the flat median has risen by 79 per cent, the house median by 46 per cent. Today the flat is 11 per cent above the canton, the house 2 per cent below.
What this means for you: if you own a flat in Bassersdorf, take the tax as seriously as a house owner would. Purchase date, receipts and your next home count just as much for you. A smaller flat is no protection against a large tax bill.
How do owners in Bassersdorf reduce the tax legally?
With time. From 20 full years of ownership the tax is halved.1 For the house in the example it would then be CHF 164,700 instead of CHF 184,464. A purchase from 2007 reaches that threshold in 2027.
With receipts. The purchase price, value-adding investments and customary selling costs are deducted.1 For a flat, that can be a conversion that raises its value. Replacing worn-out items, on the other hand, counts as maintenance and is not deductible.
With your next home. Did you live in the flat or house permanently and exclusively yourself? If you then buy or build a home for the same use in Switzerland within a reasonable period, the tax is deferred.1 This applies only to the extent the proceeds are used for it. What this means for you: the three levers work together, and you can only choose the date once.

How reliable are the Bassersdorf median prices?
For houses, only to a degree. The median of CHF 1,560,000 is based on 17 sales.2 The canton only publishes a median from 15 sales a year. Three houses fewer, and there would be none for 2025. The values are also provisional. Flats: 36 sales in both 2015 and 2025.
The canton estimates residential building land in Bassersdorf at CHF 1,988 per square metre in 2025, 85 per cent more than in 2015.10 For commuters, the train from Bassersdorf station to Zürich HB takes from 19 minutes, on the S 24.5
The municipal tax rate is 114 per cent, 209 per cent including the canton.3 It only affects income and wealth. In Kloten you pay about 7 per cent less cantonal and municipal tax on the same income, in Dübendorf about 11 per cent less. In Bassersdorf, 18.1 per cent of the population are 65 or older.4 What this means for you: your house needs its own valuation, not a village average.
What applies to the value capture levy in Bassersdorf?
Bassersdorf revised its zoning regulations in 2022; they have been fully in force since February 2024. They provide for a levy of its own: 25 per cent of the gain in value minus CHF 100,000.6 Plots under 2,000 square metres are generally exempt.6 Only the rise in value from upzoning or rezoning is covered.
The levy only falls due on development, not on sale.9 If the plot is sold first, the obligation passes to the buyer and belongs in the sale contract.8 For an upzoned or rezoned plot it therefore plays a part in the price negotiation. More in the guide to the value capture levy.

Is it worth waiting until 2027 to sell?
That depends on the purchase date. For a purchase in 2007, twenty full years are reached in 2027; in the house example the tax then falls from CHF 184,464 to CHF 164,700. Whether waiting pays off also depends on price trends, the mortgage and your circumstances.
