Zurich canton + city of Zurich only. Switzerland has no flat national tax rate: every canton and municipality sets its own multiplier. This calculator models federal tax plus the Canton of Zurich and City of Zurich multipliers specifically. Other cantons (Zug, Geneva, Schwyz, Basel...) and other Zurich-canton municipalities have meaningfully different effective rates.
Swiss salaries are commonly paid as 13 monthly payments (13. Monatslohn). If your contract quotes a monthly figure, multiply by 13, not 12, to get your true annual gross, or enter your annual figure directly above.

Calculations use 2026 rates for Federal tax, Canton of Zurich (95% Staatssteuerfuss), and City of Zurich (119% Gemeindesteuerfuss) only: other cantons and municipalities have different multipliers and can differ substantially. Federal and cantonal bracket boundaries are reconstructed from published anchor points (confirmed floor/ceiling rates and multipliers) rather than the full official step table, so treat exact franc thresholds as indicative. BVG assumes a standard 50/50 employer/employee contribution split; your actual pension plan may differ. Assumes single taxpayer, no dependents. For precise figures, consult a Swiss tax adviser or the official ZH Steueramt calculator.

Contract median
CHF 1'002/day
≈ CHF 220'440 gross a year
At a median CHF 1'002/day, contract work grosses about CHF 220'440 a year over 220 billable days, 50% more than the CHF 147'000 permanent median. That premium has to pay for what an employer would otherwise cover: paid holiday and sick days, pension contributions, and the gaps between contracts.
Contract and permanent benchmarks come from separate samples, so treat the gap as a guide rather than a like-for-like quote. See AI Research Scientist contract rates and contractor take-home →
