ChangeGPS Tax Plan supports five entity types: Individual, Company, Trust, Partnership, and Self-Managed Superannuation Fund (SMSF). You can add any combination of these entity types to a single Tax Plan, allowing you to model the full tax position of a client group — for example, a family with an individual, a discretionary trust, and a company — in one analysis. Each entity appears as a column in the workspace, and income, deductions, and adjustments are entered per entity. Tax calculations are performed for every entity in the group simultaneously across all scenarios.
