Tis the (tax) season. Watch out for scammers!

Remember that the IRS will never initially contact a taxpayer via email or by telephone about a bill or tax refund. No legitimate agency is going to ask you to pay your alleged tax bill using gift cards, iTune cards or any other type of non-cash payment.  No one is going to throw you in jail if a tax bill isn’t paid in the next 8 hours.   If you get a pop up on your computer screen that says you are infected with a virus and need to click on the link below or call a phone number for help DON’T DO IT!  Shut your computer off immediately and get help from a legitimate source. 

If you have any questions about your tax account, if you receive a suspicious email, or if you think that you have been the victim of identity theft, please do not hesitate to contact us for assistance.
