Taxes in the canton of Aargau

Aargau lives, for tax, off its location between Zurich, Basel, Bern and Lucerne: a solid mid-table burden, but direct competition with four large regions — which disciplines the municipal multipliers. For commuters into the surrounding centres, the canton is among Switzerland’s most popular places to live, precisely because the combination of tax burden and housing costs often comes off better than in the central cantons themselves.
