If an IRS agent makes an in-person visit to your home or business and it feels a little off, ask for credentials.

All real IRS agents should carry two forms of identification showing that they’re legit – a personal identity verification card and a pocket commission card. And regardless of how an agent is contacting you, you can always ask for his/her name, badge number and phone number and call the IRS at 1-800-366-4484 to confirm the agent is a true employee.
