How to Call the IRS, HMRC, CRA or Social Security From Abroad

The international phone numbers and opening hours for the IRS, HMRC, the Canada Revenue Agency and the US Social Security Administration, and the cheapest way to call them.

If you live abroad, you still deal with the tax office at home: a missing refund, a letter you do not understand, a pension question. The domestic toll-free numbers often do not work from abroad, and calls on roaming are expensive, especially when you wait on hold for 30 minutes or more.
