Method, policy basis, and limitations
How the estimate is built
The calculator resolves the effective rate for the selected transaction date and either adds tax to the net amount or extracts tax from a tax-inclusive amount.
Important limitation
GCT treatment depends on the supplier, customer, place and type of supply, exemptions, and zero-rating rules. The turnover indicator is not a registration determination or tax opinion.
Your inputs
Enter the values you know. Required fields should be completed first, and optional fields can be left blank if they do not apply to your situation.
Run the calculator to see the planning signal, key measures, reconciliation detail, and any schedules or stress scenarios returned for these inputs.
Your results
