In an update of an annual consumer alert, the Internal Revenue Service urges taxpayers to avoid falling victim to one of the "Dirty Dozen" tax scams. In the new 2003 ranking, several new scams have reached the top of the consumer watch list.

“With the tax season in full swing, we're seeing the traditional upswing in tax trickery,” said acting IRS Commissioner Bob Wenzel. “Year after year, con artists across the nation try pulling a fast one on honest taxpayers with different types of miracle tax solutions. Don't be fooled by the 'Dirty Dozen' and other misleading scams. There is no secret way to get out of paying taxes.”

The IRS urges people to avoid these common schemes:

1. Offshore transactions. Some people use offshore transactions to avoid paying United States income tax. Use of an offshore credit card, trust or other arrangement to hide or underreport income or to claim false deductions on a federal tax return is illegal.
     Through April 15, the IRS is offering people with improper offshore financial arrangements a chance to make things right. Eligible taxpayers who step forward will not face civil fraud and information return penalties. A taxpayer involved in these schemes who does not come forward now, however, will be subject to payment of taxes, interest, penalties and potential criminal prosecution.
2. Identity theft. The IRS is aware of at least two recent identity theft scams involving taxes or the IRS. In one, tax preparers allegedly used information, such as Social Security numbers and financial information, from their clients' tax returns to commit identity theft. In another, fraudsters sent bank customers fictitious bank correspondence and IRS forms in an attempt to trick them into disclosing their personal and banking data.
3. Phony tax payment checks. In this scheme, con artists sell fictitious financial instruments that look like checks to pay a tax liability, mortgage and other debts. The con artists may also counsel their clients to use a phony check to overpay their taxes so they can receive a refund from the IRS for the overpayment. The false checks, called sight drafts, are worthless and have no financial value. It is illegal to use these sight drafts to pay a tax liability or other debts.
4. African-American, special tax refund. Thousands of African-Americans have been misled by people offering to file for tax credits or refunds related to reparations for slavery. There is no such provision in the tax law. Taxpayers could face a $500 penalty for filing such claims if they do not withdraw the claim.
5. No taxes withheld from wages. Illegal schemes are being promoted that instruct employers not to withhold federal income tax or employment taxes from wages paid to their employees. These schemes are based on an incorrect interpretation of tax law and have been refuted in court.
6. Improper home-based business. This scheme purports to offer tax “relief” but in reality is illegal tax avoidance. The promoters of this scheme claim that individual taxpayers can deduct most, or all, of their personal expenses as business expenses by setting up a bogus home-based business. But the tax code firmly establishes that a clear business purpose and profit motive must exist in order to generate and claim allowable business expenses.
7. Pay the tax, then get the prize. The caller says you've won a prize, and all you have to do to get it is to pay the income tax due. Don't believe it. Someone who really wins a prize may need to make an estimated tax payment to cover the taxes that will be due at the end of the year. But the payment goes to the IRS - not the caller. Whether the prize is cash, a car or a trip, a legitimate prize giver generally sends both the winner and the IRS a Form 1099 showing the total prize value that should be reported on the winner's tax return.
8. Frivolous arguments. Frivolous arguments are false arguments that are unsupported by law. When a scheme promoter says “I don't pay taxes - why should you” or urges you to “untax yourself for $49.95,” beware. The ads may say that paying taxes is “voluntary,” but U.S. courts have continuously rejected this and other frivolous arguments. Unfortunately, hundreds of people across the country have paid for the “secret” of not paying taxes or have bought “untax packages.” Then they find out that following the advice contained in them can result in civil and/or criminal penalties.
9. Social security tax scheme. Taxpayers shouldn't fall victim to a scam offering refunds of the Social Security taxes they have paid during their lifetimes. The scam works by the victim paying a “paperwork” fee of $100, plus a percentage of any refund received, to file a refund claim with the IRS. This hoax fleeces the victims for the up-front fee. The law does not allow such a refund of Social Security taxes paid. The IRS processing centers are alert to this hoax and have been stopping the false claims.
10. “I can get you a big refund...for a fee!” Refund scheme operators may approach someone wanting to “borrow” their Social Security number or give him or her a phony W-2 so it appears that the person qualifies for a big refund. They may promise to split the refund with that person, but the IRS catches most of these false refund claims before they go out. And when one does go out, the participant usually ends up paying back the refund along with stiff penalties and interest.
11. Share/borrow EITC dependents. Unscrupulous tax preparers “share” one client's qualifying children with another client in order to allow both clients to claim the Earned Income Tax Credit. The IRS prosecutes the preparers of such fraudulent claims, and participating taxpayers could be subject to civil penalties.
12. IRS “agent” comes to house to collect. IRS special agents, field auditors and collection officers carry picture IDs and will normally try to contact you before they visit. If you think the person on your doorstep is an impostor, lock the door and call the local police. To report IRS impostors, call the Treasury Inspector General's Hotline at 1-800-366-4484.
