September first is the beginning of National Payroll Week - a time for working folks everywhere to learn how to get more out of their paychecks. Money experts say paying more attention to the deductions that come out of your salary can help you hold onto to what you`ve worked for. If you normally get a big tax refund, that may mean you`ve had too much withheld - in effect giving the government an interest-free loan. Experts with MYPAYCHECK.COM also say flexible spending accounts for health, commute and child care costs can help you extend your salary. Such accounts create pre-tax pools of money to handle expenses.
