PHOENIX ' Starting this month, the Internal Revenue Service will begin sending letters to a relatively small group of taxpayers whose overdue federal tax accounts are being assigned to one of four private-sector collection agencies.

The new program, authorized under a federal law enacted by Congress in December 2015, enables these designated contractors to collect, on the government's behalf, unpaid tax debts. Usually, these are unpaid individual tax obligations that are not currently being worked by IRS collection employees and often were assessed by the tax agency several years ago.

Taxpayers being assigned to a private firm would have had multiple contacts from the IRS in previous years and still have an unpaid tax bill.

"The IRS is taking steps throughout this effort to ensure that the private collection firms work responsibly and respect taxpayer rights," said IRS Commissioner John Koskinen. "The IRS also urges taxpayers to be on the lookout for scammers who might use this program as a cover to trick people. In reality, those taxpayers whose accounts are assigned as part of the private collection effort know they have a tax debt."

The program will begin this week with a few hundred taxpayers receiving mailings and subsequent phone calls, with the program growing to thousands a week later in the spring and summer. Taxpayers with overdue taxes will always receive multiple contacts, letters and phone calls, first from the IRS, not private debt collectors.

How the New Program Works

The IRS will always notify a taxpayer before transferring their account to a private collection agency (PCA). First, the IRS will send a letter to the taxpayer and their tax representative informing them that their account is being assigned to a PCA and giving the name and contact information for the PCA. This mailing will include a copy of Publication 4518, What You Can Expect When the IRS Assigns Your Account to a Private Collection Agency.

Only four private groups are participating in this program: CBE Group of Cedar Falls, Iowa; Conserve of Fairport, N.Y.; Performant of Livermore, Calif.; and Pioneer of Horseheads, N.Y. The taxpayer's account will only be assigned to one of these agencies, never to all four. No other private group is authorized to represent the IRS.

Once the IRS letter is sent, the designated private firm will send its own letter to the taxpayer and their representative confirming the account transfer. To protect the taxpayer's privacy and security, both the IRS letter and the collection firm's letter will contain information that will help taxpayers identify the tax amount owed and assure taxpayers that future collection agency calls they may receive are legitimate.

The private collectors will be able to identify themselves as contractors of the IRS collecting taxes. Employees of these collection agencies must follow the provisions of the Fair Debt Collection Practices Act, and like IRS employees, must be courteous and must respect taxpayer rights.

The private firms are authorized to discuss payment options, including setting up payment agreements with taxpayers. But as with cases assigned to IRS employees, any tax payment must be made, either electronically or by check, to the IRS. A payment should never be sent to the private firm or anyone besides the IRS or the U.S. Treasury. Checks should only be made payable to the United States Treasury. To find out more about available payment options, visit IRS.gov/Payments.

Private firms are not authorized to take enforcement actions against taxpayers. Only IRS employees can take these actions, such as filing a notice of Federal Tax Lien or issuing a levy. To learn more about the new private debt collection program, visit the Private Debt Collection page on IRS.gov.

Watch out for Phone Scams

The IRS reminds taxpayers to be on the lookout for scammers posing as private collection firms. The IRS will be watching for these schemes as the collection program begins, and this effort will include working with partners in the tax community and law enforcement about emerging scams.

People should remember that these private collection firms will only be calling about a tax debt the person has had - and has been aware of - for years and had been contacted about previously in the past by the IRS.

"Here's a simple rule to keep in mind. You won't get a call from a private collection firm unless you have unpaid tax debts going back several years and you've already heard from the IRS multiple times," Koskinen said. "The people included in the private collection program typically already know they have a tax issue. If you get a call from someone saying they're from one of these groups and you've paid your taxes, that's a sure sign of a scam."

If taxpayers are unsure if they have an unpaid tax debt from a previous year - which is what the private collection firms will handle - they can go to IRS.gov and check their account balance: www.irs.gov/balancedue. If the account balance says zero, that means nothing is due, and you typically wouldn't be getting a contact from the IRS or the private firm.

Whether or not a taxpayer's account is assigned to a private collection agency, the IRS warns taxpayers to beware of scammers pretending to be from the IRS or an IRS contractor. Here are some things the scammers often do but the IRS and its contractors will never do:

• Call to demand immediate payment using a specific payment method such as a prepaid debit card, gift card or wire transfer. Generally, the IRS will first mail a bill to any taxpayer who owes taxes, and if a case is assigned to a PCA, both the IRS and the authorized collection agency will send the taxpayer a letter. Payment will always be to the United States Treasury.
• Threaten to immediately bring in local police or other law-enforcement groups to have the taxpayer arrested for not paying.
• Demand that taxes be paid without giving the taxpayer the opportunity to question or appeal the amount owed.
• Ask for credit or debit card numbers over the phone.

"Unexpected and threatening calls out of the blue from someone saying they're representing the IRS to collect a tax debt is a warning sign people should watch out for," Koskinen said.

Don't Wait to Hear from the IRS or a Contractor

As always, the IRS encourages taxpayers behind on their tax obligations to come forward and either pay what they owe or set up a suitable payment plan. This means there's no need to wait for a phone call or letter from the IRS or any of its contractors.

Frequently, taxpayers qualify for one of several payment options, and taking advantage of them is often easier than many people think. These include the following:

• Most people can set up a payment agreement with the IRS online in a matter of minutes. Those who owe $50,000 or less in combined tax, penalties and interest can use the Online Payment Agreement to set up a monthly payment agreement for up to 72 months. Taxpayers can choose this option even if they have not yet received a bill or notice from the IRS. With the Online Payment Agreement, no paperwork is required, there is no need to call, write or visit the IRS and qualified taxpayers can avoid the filing of a Notice of Federal Tax Lien if one was not previously filed. Alternatively, taxpayers can request a payment agreement by filing Form 9465. This form can be downloaded from IRS.gov and mailed along with a tax return, bill or notice.
• Some struggling taxpayers may qualify for an offer-in-compromise. This is an agreement between a taxpayer and the IRS that settles the taxpayer's tax liabilities for less than the full amount owed. The IRS looks at the taxpayer's income and assets to make a determination regarding the taxpayer's ability to pay. To help determine eligibility, use the Offer in Compromise Pre-Qualifier, a free online tool available on IRS.gov.

"If people have a problem paying their tax bill, we encourage them to reach out to us," Koskinen said. "We have many programs designed to help people who are having trouble meeting their tax obligations. It's better to reach out to us sooner rather than later for help, because interest and penalties on unpaid taxes can add up quickly."
