IRS FORMS AND LINKS:

WHAT TO EXPECT
Before a Coast representative calls to help resolve your overdue taxes, you will receive two letters:
- Notice CP40 and Publication 4518 from the IRS. These documents let you know that your overdue tax account was assigned to a private collection agency, and
- A letter from Coast, with instructions on how to resolve your debt.
Both of these letters contain a Taxpayer Authentication Number that is used to confirm your identity. Have it available when calling Coast.
Throughout the debt resolution process, letters and phone calls will be the only ways we reach out to taxpayers. During each phone call, the representative will identify him or herself as a Coast employee working on behalf of the IRS and take you through the authentication process to verify your identity. Private collection agencies such as Coast working on behalf of the IRS will not contact you via email or text.
MAKING PAYMENTS
Payments can only be made directly to the IRS or through a Pre-Authorized Direct Debit with Coast drafting a check on your behalf. Additional information on the Pre-Authorized Direct Debit payment method is available by contacting Coast at (888) 928-0510.
Payments by check are to be mailed directly to the IRS at the following address:
Department of the Treasury
Internal Revenue Service
Kansas City, MO 64999-0010
To make online payments or apply for a payment plan with the IRS at www.irs.gov/payments.
You will never be asked to pay with a pre-paid debit card or wire transfer. If this occurs, or if anyone other than Coast calls you about your debt, it is a scam.
