How to Call IRS from Abroad (Without SIM or Roaming)
If you’re outside the U.S. and need to reach the IRS for tax inquiries, using your local phone plan can get expensive fast. International calls to U.S. toll-free numbers often fail, and some VoIP apps are unreliable for important government calls. Even dialing from a hotel or using a local SIM may not work or could incur high charges.
This guide shows the easiest way to call the IRS from anywhere in the world without paying roaming fees or installing any apps. You’ll get step-by-step instructions and all the IRS numbers you might need.

Why Calling IRS from Abroad Often Fails
Most U.S. toll-free numbers, like 1-800 numbers, won’t work from outside the U.S. Even if you use the IRS’s international numbers, you might still face:
- High roaming charges ($3–10 per minute)
- Dropped calls or poor connections
- Keypad menus not working properly
| Method | Why It Fails |
|---|---|
| Hotel Phone | Expensive, limited control |
| Local SIM Direct Dial | Blocked or high cost |
| Skype/WhatsApp | Often blocked for government calls |
Tips for Calling IRS
- Have your information ready: Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), tax return, and any IRS notices
- Know your issue: write down specific questions or concerns before calling
- Check U.S. time zones: IRS operates on Eastern Time (ET) for phone support
- Be prepared to wait: IRS phone lines can have long wait times, especially during tax season (January–April)
- Keep records: write down any reference numbers or agent names for follow-up
