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

Traditional carriers charge $1-3/minute for international calls to the US. Without a special plan, T-Mobile charges $3/minute from most European countries. Verizon starts at $0.49/minute.

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: 30 minutes at $2/minute = $60 just to 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 at a fraction of carrier rates.

VoIP services

DialHard: Browser-based (no app needed). Rates from $0.03/minute to US numbers. Toll-free calls (1-800, 1-888, etc.) are free—first 5 minutes daily with 98% completion rate. Credit never expires. Minimum purchase $20.

Viber Out: App-based. Rates from ~$0.01/minute to US. Minimum ~$5. Credit expires after 180 days.

Google Voice: Free for US residents—calls to US numbers are free. Only available to US residents with a US phone number.

The toll-free advantage

Most IRS numbers are toll-free (1-800). If your VoIP service routes toll-free calls for free, you can wait on hold without racking up charges. DialHard offers this—critical when IRS hold times exceed 30 minutes.
