How to prepare for a call to the IRS

The right number depends on whether you need individual, business, appointment or notice-specific help. A complete file makes it easier to pass authentication and explain the issue.

Quick principle

Use the official online or phone route first when it can solve the task. If you need in-person help, schedule the appointment and bring a complete file.

Choose the correct number

Start with the contact information on your notice when you have one. Use 844-545-5640 specifically for scheduling a Taxpayer Assistance Center appointment.

Prepare to authenticate

Have taxpayer identification numbers, filing status, the return in question and recent account information nearby. Third-party callers need valid authorization.

Keep a call record

Write down the date, representative identification, case or reference number, instructions and any promised timeframe. Do not share login passwords or full payment-card credentials.
