Con artists use personally identifiable information of unsuspecting consumers to file phony tax returns and steal refunds.
Consumers and businesses aren't the only ones preparing for tax season; so are the scammers.

In Canada, there are a variety of ways to minimize your risk when preparing for tax season. The Canadian Revenue Agency has these tips to protect yourself from identity theft.
Be aware of online identity theft with these tips.
How tax identity theft scams work:

Online filers that go through the IRS or CRA website usually expect a refund. Instead, a written notice arrives in the mail, stating that more than one tax return was filed using your information.
What happened? Scammers got hold of personal information, typically the account holder's Social Security or Social Insurance number, address, and birth date. They filed your return early and received your refund before you even got around to filing. Tax ID theft is a particularly sneaky con, because victims typically don’t realize they’ve been targeted until they actually file their taxes.
Scammers steal tax information in several ways, such as a phishing scam, a corrupt tax preparation service, or the information was exposed in a hack or data breach. Sometimes tax scammers file in the name of a deceased person or steal children’s identities to claim them as dependents.
