Tax Return Basel-Stadt – How much tax will I pay?
Unlike most other cantons, in Basel-Stadt you pay roughly the same tax almost regardless of where you live: the canton consists of only three municipalities with very similar tax multipliers — "municipality hopping" like in Zurich or Bern barely pays off here.
| Net income (4000 Basel) | Total tax | Marginal tax rate |
|---|---|---|
| CHF 80’000 | CHF 18’178 | 26.9% |
| CHF 120’000 | CHF 29’449 | 29.8% |
| CHF 200’000 | CHF 54’903 | 34.2% |

The rate shown is the marginal tax rate (the rate on your next franc earned), not the average effective rate. Your actual tax load depends on your deductions — we check that individually.

What makes canton Basel-Stadt different
Only three municipalities: Basel, Riehen, Bettingen
Basel-Stadt is Switzerland's smallest canton by area and consists of just three municipalities. Unlike most other cantons, you don't need to weigh municipalities with sharply different tax multipliers against each other here.
Online only: eSteuern BS
The tax software BalTax is available exclusively online. We file your tax return directly through that same official channel — no printing, no posting a signature.
Low commuting allowance, high further-education deductions
Basel-Stadt allows comparatively little for commuting, but noticeably more for further education than many other cantons. Especially if you're planning further education, this deduction is worth a close look.
