Verifying Identity and Avoiding Identity Theft

In an ongoing effort to protect taxpayers from identity theft, the IRS, state tax agencies and the tax industry are asking for driver’s license numbers or state-issued identification numbers. Providing this information helps verify identity and can prevent unnecessary delays in tax return processing.

The department urges taxpayers to be cautious of companies or individuals offering free incentives or trying to collect money.

Keep in mind that ADOR will never:

  • Use text messages or any social media to discuss personal tax issues.
  • Call to demand immediate payment; nor will we call about taxes owed without first having mailed an official demand notice.
  • Demand that individuals pay taxes without giving them opportunity to question or appeal the stated amount owed.
  • Require taxpayers to use a specific payment method to pay their taxes, such as a prepaid debit card.
  • Threaten to bring in local police or other law-enforcement groups to have a taxpayer arrested for not paying.


Those individuals who suspect misuse of their Social Security numbers should contact the Federal Trade Commission for assistance. The agency can be reached at (877) IDTHEFT (877-438-4338). Information is also available at
