Tax collection scams are among the most stubborn cons out there. They reappear often, each time with a slightly different spin. The main theme is scammers posing as the Internal Revenue Service (IRS) in the U.S. or as the Canada Revenue Agency (CRA) in Canada, and trying to trick you into either paying up or sharing personal information.How the Scam Works:These scams most often start with a phone call and take two basic forms. In the first version, the IRS or CRA "agent" says you owe back taxes and pressures you into paying by prepaid debit card or wire transfer. If you don’t comply, the scammer threatens you with arrest and fines. In the other version, scammers claim they are issuing tax refunds and ask you for personal information so they can send your refund. This information can later be used for identity theft. These imposters often go to great lengths to appear real. The scammer may give a fake badge number and name. Your Caller ID may look like the call is coming from Washington, D.C. or Ottawa. In many instances, these scams start with a serious and official sounding “robocall” recording.Tips to Spot This Scam: You are pressured to act quickly. Scammers typically try to push you into action before you have time to think. The IRS and CRA will give you the chance to ask questions or appeal what you owe. Also, their first contact with you will always be by mail, not phone or email. Payment must be made by wire transfer, prepaid debit card, or other non-traditional payment methods. These methods are largely untraceable and non-reversible. The IRS and CRA will never demand these forms of payment.In the U.S., the IRS may call you about outstanding debts after reaching out by mail.

This occurs when a scammer uses your government-issued identity number (Social Security number in the U.S. or Social Insurance number in Canada) to file a tax return in your name and collect your refund. It can also be someone using your information to get a job. Consumers don’t usually realize they have been victims of tax identity theft until they get a written notice from the IRS or CRA saying that more than one tax return was filed, or they were paid by an employer they don't know.The best way to avoid tax identity theft is to file your taxes as early as possible, before a scammer has the chance to use your information to file a fake return. In the U.S., you can also get an Identity Protection PIN (IP PIN) from the IRS before you file your return. This is a six-digit number, which, in addition to your Social Security number, confirms your identity. It is important to note that you cannot opt-out once you get an IP PIN. So once you apply, you must provide the IP Pin each year when you file your federal tax returns. The IRS will provide your IP PIN online and then send you a new IP PIN each December by postal mail.

You should also file a complaint with the Federal Trade Commission (FTC) at ftc.gov/complaint or by calling 1-877-FTC-HELP. The FTC also offers a personalized identity theft recovery plan at identitytheft.gov. If you are a victim in Canada, contact your local police service. If you believe your Canadian Social Insurance Number has been stolen, contact Service Canada at 1-800-206-7218. For more information, see Social Insurance Number (Service Canada website).Refund AdvancesSome tax preparers offer Refund Advances, which are essentially short-term loans in the amount of your expected tax return, less the tax preparation cost. The upside of these loans is that you can get the money right away. However, you should consider whether receiving your refund a couple of weeks sooner is worth the cost of the tax preparation service. Also look out for large deductions from the refund amount to cover fees.To report a scam, go to BBB Scam Tracker.To learn how to protect yourself, go to “10 Steps to Avoid Scams”.Last Reviewed: February 9, 2018BBB Serving Metro Atlanta, Athens & Northeast Georgia contributed to this tip.
