The state Department of Taxation and Finance is warning taxpayers about some unscrupulous tax preparers, as St. Lawrence County residents get their income tax returns done before the Wednesday deadline.

According to state authorities, here’s how the scam works: The taxpayer - unfamiliar with the tax forms - is led to believe the refund is $200, when his actual refund is $2,000. The dishonest preparer pays the taxpayer the $200 on the spot. The preparer then arranges for the actual refund of $2,000 to be deposited into another bank account, stealing the $1,800 difference.

The vast majority of paid preparers provide honest, professional advice and service, the department says, but scams such as this are reminders that taxpayers must remain vigilant.

There are steps to take for those using the services of a tax preparer:

• Have the preparer review your return with you before you sign it

• Never sign a blank or incomplete return

• Make sure your preparer signs the return appropriately

• Do not let the preparer deposit your refund into his or her checking account - have your refund deposited directly into your own bank account or sent directly to you on a debit card

• Keep a copy of your completed and signed tax forms

• Report tax evasion or fraud
