The dates displayed here are the dates you selected in the Select Date Range
for Liabilities window.
To change this date, click the Date drop-down list and choose a date range, or enter dates in
the From and Through fields.
When you pay the liabilities, QuickBooks tracks the payment of those
liabilities for this period (regardless of the check date). It can then report
payments against liabilities by month or quarter on Form 941 and Form 940.
