Staying Safe from Tax Scams
From the offices of Cybersecurity and Identity____________________
Though Benjamin Franklin is often quoted as saying "in this world, nothing
can be said to be certain, except death and taxes," an updated version for
the current day would need to include tax scams. As people nationwide seek
to file their tax returns, cybercriminals attempt to take advantage of this
with a variety of scams. Hundreds of thousands of U.S. citizens are targeted
by tax scams each year, often only learning of the crime after having their
legitimate returns rejected by the Internal Revenue Service (IRS) because
scammers have already fraudulently filed taxes in their name. The IRS
reported a 400% rise in phishing scams from the 2015 to the 2016 tax season.
In the state, local, tribal, and territorial government sector during 2017,
approximately 30% of all reported data breach incidents were related to the
theft of W-2 information, which was likely used for tax fraud.

How is Tax Fraud Perpetrated?
Unfortunately, much of your personal information can be gathered from
multiple locations online with almost no verification that the right person
is receiving the information. Criminals know this, so they use this trick to
get your personal information from a variety of websites and use the
information to file a fake tax refund request! If a criminal files a tax
return in your name before you do, they will file it with false information
to get a large refund, forcing you to go through the arduous process of
proving that you did not file the return and subsequently correcting the
return. Once they have your personal information, criminals can continue to
commit identity theft well beyond the tax season.
Another favorite technique used by criminals during the tax season is
sending phishing messages indicating that a new copy of your tax form(s) is
available. These emails often impersonate state, local, tribal, and
territorial government comptroller and/or IT departments. They might include
a link to a phishing website that uses your organization's logo and the
email might even have the right signature line. If you fill out or attempt
to login into the phishing website, the criminals will be able to see your
login name and password, which they can then use to try and compromise your
other accounts. The more information they gather from you, the easier it is
for them to use the information to file a fake tax return in your name.
Tax fraudsters also impersonate the IRS and other tax officials to threaten
taxpayers with penalties if they do not make an immediate payment. This
contact may occur through websites, emails, or threatening calls and text
messages that look official but are not. Sometimes, criminals request their
victims pay the "penalties" via strange methods like gift cards or prepaid
credit cards. It is important to remember:
. The IRS will not initiate contact about payment with taxpayers by
phone, email, text messages, or social media without sending an official
letter in the mail first.
. The IRS will not call to demand immediate payment over the phone
using a specific payment method such as a debit/credit card, a prepaid card,
a gift card, or a wire transfer.
. The IRS will not threaten to immediately notify local police or
other law-enforcement agencies to have you arrested for not paying.
. The IRS will not demand that you pay taxes without giving you the
opportunity to question or appeal the amount you owe.
What Can You Do?
Here are some basic tips to help you minimize the chances of becoming a
victim of a tax scam:
. If you haven't already, file your taxes as soon as you can.before
the scammers do it!
. Be aware of phone calls, emails, and websites that try to get your
information, or pressure you to make a payment. If something seems
suspicious, contact the organization through a known method, like their
publicly posted customer service line.
. Ignore emails and texts asking for personal or tax information. Be
cautious as to whom you provide your information, including your Social
Security Number and date of birth.
. Don't click on unknown links or links from unsolicited messages.
Type the verified, real organizational website into your web browser.
. Don't open attachments from unsolicited messages, as they may
contain malware.
. Only conduct financial business over trusted websites. Don't use
public, guest, free, or insecure Wi-Fi networks.
. Remember, the "HTTPS" does not mean a site is legitimate.
. Shred all unneeded or old documents containing confidential and
financial information.
. Check your credit report regularly for unauthorized activity.
Consider putting a security freeze on your credit file with the major credit
bureaus if you suspect you have been targeted for identity theft.
If you receive a tax-related phishing or suspicious email at work, report it
according to your cybersecurity policy. The IRS encourages taxpayers to send
