All tax and royalty regimes are calculated in cash formulas. Fiscal models are a collection of cash formulas that model tax calculations for certain countries or states. PHDwin has default fiscal models written for the United States, which are available in the Fiscal Models form. To model another country’s fiscal regime, contact the consulting team for further assistance.

Viewing Applied Fiscal Models

To view the fiscal regime that has been applied to a case, click on the Forms Flyout and then double-click on Tax and Custom Models. On the left-hand side of the Tax and Custom Models form, a list of available Fiscal Models in the database is displayed. If a fiscal model has been applied to the case, a checkbox is placed next to the State name (for United States) and the tax rates are displayed on the right pane as State/Local Taxes.
