How to Call the IRS from Abroad: Complete Guide for 2026


If you're a US citizen living abroad, an expat, or a foreign national with US tax obligations, you may need to call the IRS. The challenge: expensive international rates combined with long hold times.

Why is calling the IRS from abroad so expensive?

Three factors combine to make IRS calls costly from overseas:

Carrier international rates

Without a plan that covers calls to the US, your carrier charges its standard per-minute international rate. Carriers list these on their international calling pages.

The "toll-free trap"

US toll-free numbers (1-800, 1-888, etc.) are only free within the US. International callers pay their carrier's international rates to reach these numbers—often the same as calling any US number. Some carriers even block toll-free calls from abroad.

IRS wait times

Average IRS hold times exceed 30 minutes. During tax season (January–April) or on Mondays/Tuesdays, waits can extend beyond an hour. Post-filing season, wait times can triple.

The math: every minute of a 30-minute hold is billed at your per-minute rate before you reach an agent. If the call drops, you start over.

What are the cheapest ways to call the IRS from abroad?

VoIP (Voice over IP) services let you call US numbers through the internet.
