PROTECT YOURSELF! The IRS will never: ** Call to demand immediate payment, nor will the agency call about taxes owed without first having mailed a bill. ** Demand that payment of taxes without giving you the opportunity to question or appeal the amount he or she owes. ** Require you to use a specific payment method for taxes, such as a prepaid debit card. ** Ask for credit or debit card numbers over the phone. ** Threaten to bring in local police or other law-enforcement groups to have you arrested for not paying.
