Note that for pre-existing calculations using this feature where Germany is the host country, the cost estimate will need to be updated to set the tax position to Yes on the home estimator. Going forward, the tax position will be present on the home estimator for each country that has at least one enhanced agreement.
New Swiss Canton: Valais
Added support for the Swiss canton of Valais, bringing the total number of supported cantons to 10. Situated in the southwestern portion of Switzerland, Valais borders Italy and France. French and German are its two official languages, and Sion is its capital and the largest city. The top cantonal and communal rates of 14% and 10%, respectively, are imposed on taxable income above CHF 200,000.
Canton-Specific Tax Positions
As with other supported cantons, the communal coefficient can be overridden by using the Communal Rate Override input. Unique to Valais, a Communal Indexation Override input is also provided to override the indexation value that is used to determine the applicable communal tax bracket. The default communal coefficient and indexation rate used are 1.10 and 176%, respectively, which correspond to the capital city of Sion.
Cantonal Family Allowance Contributions
As with all other supported cantons, a family allowance contribution is calculated as part of Switzerland social security. Employer and employees contribute at rates of 3.16% and 0.171%, respectively.
Features
The current release includes several features which enhance the functionality of the Equus Platform.
France

Private Health Insurance deduction calculates.
Social security excludes employee and employer Health Insurance and Nursing contributions for actual calculations but includes them for hypothetical calculations. Note that when Tax Calculation Method is set to Grossup Only, the without side of the calculation will continue to follow the behavior on the with side to ensure a valid grossup is calculated (i.e. it will behave as if Yes is selected for Contributes to Private Health Insurance?).
