Tax return in Vaud

The Vaud tax return can be submitted online through the cantonal tax administration (ACI) portal. You must declare your income, assets, deductions, and attach the required supporting documents in PDF format. The standard deadline is March 15 of each year.

The lowest-taxed municipalities in Vaud are mainly located on the Riviera and in the Nyon district. Among the most tax-advantageous municipalities are Montricher, Essertines-sur-Rolle, and certain municipalities in the Pays-d'Enhaut. The municipal coefficient generally ranges between 54% and 79% of the base cantonal tax. The choice of municipality of residence can represent a difference of several thousand francs on the annual tax bill.

An extension request can be submitted online on the ACI portal before the March 15 deadline. A first extension until June 30 is generally granted free of charge. Additional extensions can be requested for a fee of CHF 50. In case of non-filing, the administration sends reminders before proceeding with an ex officio assessment, which is often unfavorable to the taxpayer.
