Canadian contractors are not subject to US tax reporting requirements like Form 1099 because they are not US residents or citizens. Instead, Canadian contractors may receive their own country's equivalent tax forms or documentation from their clients or employers in Canada, depending on local tax regulations.
The IRS requires a flat 30% withholding on ALL types of payments to foreign national individuals UNLESS: The individual has a U.S. tax identification number (SSN or ITIN) and qualifies for a tax reduction under the tax treaty between the U.S. and their country of tax residency.
Instead of filling out a 1099, when you hire Canadian contractors, you should request a completed W-8BEN from them. This form ensures compliance with the IRS and the Canada-US tax treaty; without it, you are required to withhold and remit 30% tax on all contractor earnings.
If you want to maintain control and manage employees directly, you can hire Canadian workers as independent contractors, or freelancers.
Federal law requires U.S. citizens and resident aliens to report their worldwide income, including income from foreign trusts and foreign bank and other financial accounts.
Independent contractors generally report their income on Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship). Also file Schedule SE (Form 1040), Self-Employment Tax if your net earnings from self-employment are $400 or more.
