Closing costs in the canton of Basel-City
Overview
Basel-City sits in the top group when it comes to the tax rate — yet it has a mechanism unusual among Swiss cantons: “living without transfer tax”. If the buyer occupies the property exclusively and keeps it up for the statutory minimum period, the tax liability switches sides — the then-reduced tax is owed by the seller, and the buyer simply pays nothing. Giving up owner-occupation early triggers retroactive taxation. Deeds are notarized by independent notaries under a state-fixed, degressive tariff; the land register charges per mille with a floor and a ceiling.
Rates, who pays, source and check date for every block are gathered in the table; what the switch of liability means in francs is shown by the calculator. The canton overview serves the comparison, and the underlying principle is explained in the guide to the transfer tax.

Frequently asked questions
Do I pay transfer tax as a buyer in Basel-City if I move in myself?
No. If the property is exclusively owner-occupied for the statutory minimum period, the — then reduced — tax is owed by the seller; the buyer pays nothing.
What happens if I move out early?
The relief is tied to uninterrupted owner-occupation over the minimum period; if that condition is broken, the law provides for retroactive taxation.
Do Riehen or Bettingen levy surcharges of their own?
No. The transfer tax is purely cantonal; municipal surcharges do not exist in Basel-City.
