You will receive a minimum of 26 and a maximum of 27 paychecks in a year. Because biweekly periods do not always line up exactly to the calendar year, there is often a biweekly pay period that crosses over from December to January. As a result, the gross pay reported on an annual W-2 tax form may not exactly match your annualized pay rate, and occasionally there will be 27 periods in one year.
