Though I don't want to be a Grinch, big tax refunds are one present you can do without. A big tax refund means your W-4 or payroll withholding form wasn't properly adjusted, and you overpaid Uncle Sam. In effect, you gave the government an interest-free loan for a year.
Some taxpayers withhold too much on purpose.
They use their W-4s to save money for property taxes and auto insurance. The problem is that those funds don't earn interest. A savings account or certificate of deposit would be a better place to put that extra money. Consider having your savings payroll deducted by your credit union. Your bank can also automatically transfer money to your savings after your paycheck is deposited.
