When a partial payment is made after interest has accrued for an amount due for a tax jurisdiction not using a compounding method, Instant Interest asks you whether to apply the payments first to accumulated interest or to outstanding taxes due.

The three buttons functions as follows:

Tax       –	Applies payments to accumulated interest first.
Interest –	Applies payments to outstanding taxes first.
Cancel  –	Abandons the calculation and returns you to the appropriate data entry panel.

Select the appropriate option by clicking on the corresponding command button.
