Protect yourself from identity theft
Identity theft is the unauthorized use of personal information such as:
Social Security number
credit card number
Identity thieves can file forged tax returns to collect fraudulent refunds and victims may not be aware their identities have been stolen.
Protect your identity by writing only the last four digits of your Social Security number on any check or money order you send to the Tax Department. You must include your complete Social Security number on your return and payment voucher. We cannot process these forms without the complete number.
