It is important not to have overlapping subsidies, this will result in double subsidies. The first step in entering a new approval is to end the previous approval. Under the child, click "Subsidy" and choose the current subsidy. Change the end date to the day before the new approval begins. Next you will enter the new approval exactly as it appears on the letter you received as a new subsidy. Now you can re-print the child's statement. The subsidy calculator on the second page will now show the new amounts. If the amounts change partway through the billing period, you will see the two different subsidies appear with different amounts for each part of the billing period.
