Quick answer

Non-US freelancers lose 24-30% of every payment to backup withholding without an ITIN. Getting one lets you submit a W-8BEN on Upwork, Fiverr, or Toptal, claim treaty benefits from 67+ countries, and deduct business expenses on Form 1040-NR. itin.so processes applications for $197-$297.

Why Do Non-US Freelancers Need an ITIN?

30% of every US-sourced payment disappears to withholding without a valid tax ID. The IRS requires platforms like Upwork, Fiverr, and Toptal to collect tax identification from every contractor under IRC 1441 and IRC 3406. Non-US individuals without an SSN use an ITIN.

The Real Cost of Missing an ITIN

A freelancer earning $5,000 per month from US clients loses $1,200 to $1,500 monthly to backup withholding. Over a year, that totals $14,400 to $18,000 in lost income. With an ITIN and valid W-8BEN, the withholding drops to 15%, 10%, or 0% based on your country's treaty with the US.

Which Platforms Require W-8BEN Filing

Every US-based freelance platform requires a W-8BEN from non-US contractors: Upwork, Fiverr, Toptal, 99designs, Catalant, and others. The form requires your ITIN, country of residence, and applicable treaty claim. Check who needs an ITIN for full eligibility.

How Do I Fill Out the W-8BEN Form in the USA?

The W-8BEN (Certificate of Foreign Status of Beneficial Owner for US Tax Withholding) establishes your non-US status and sets your withholding rate. Here is how to properly fill out a W-8BEN in 5 steps:

Part I — identify yourself. Enter your full legal name (matching your passport exactly), country of citizenship, and country of residence.
Line 5. Enter your ITIN in the US taxpayer identification number field.
Line 6. Enter your foreign tax identification number from your home country, if you have one.
Part II, Line 10.Enter your country's tax treaty article number and the reduced withholding rate for independent personal services income.
Sign, date, and submit.Submit the form through your platform's tax settings (Upwork, Fiverr, Toptal, etc.).

W-8BEN Validity Period

The W-8BEN is valid for 3 calendar years from the date you sign it, plus the remainder of the signing year. A form signed on March 1, 2026 expires December 31, 2029. Each platform sends reminders before expiration.

Common Treaty Rates by Country

Country	Treaty Article	Withholding Rate
United Kingdom	Article 14 (Independent Services)	0%
Canada	Article XIV	0%
India	Article 12 (Fees for Technical Services)	15%
Germany	Article 14	0%
No Treaty	N/A	30% (default under IRC 1441)

How Does Each Freelance Platform Handle ITIN Verification?

Upwork (10% Service Fee)

Upwork requires all freelancers to complete a tax information interview when they start earning from US clients. Non-US freelancers select W-8BEN and enter their ITIN. Upwork validates with the IRS and adjusts withholding. Upwork sends a 1042-S form at year end showing earnings and taxes withheld. Without an ITIN, Upwork withholds 30% of US-sourced earnings.

Fiverr (20% Service Fee)

Fiverr collects W-8BEN through account settings during tax onboarding. Once verified, your withholding drops from 30% to treaty rate. Fiverr issues a 1042-S annually. Note that Fiverr service fees (20% on orders up to $50, 10% on orders above $50) are separate from tax withholding and fully deductible on your Form 1040-NR.

Toptal ($60-$200/hr Contracts)

Toptal requires W-8BEN with ITIN before issuing the first payment. Because Toptal contracts average $60 to $200 per hour, the difference between 30% withholding and 0% treaty rate equals $18 to $60 per hour saved. A full-time Toptal contractor at $100/hr saves up to $124,800 per year with proper treaty claims.

What Tax Returns Do Non-US Freelancers File?

Non-US freelancers file Form 1040-NR annually to report US-sourced income. Attach Schedule C for business income and deductions. Filing deadline: June 15 for non-residents with no US wages, extendable to October 15 via Form 4868. Key deductions include:

Platform service fees (Upwork 10%, Fiverr 20%)
Software and tool subscriptions (Figma, GitHub, AWS)
Equipment (laptop, monitor, peripherals)
Internet and phone costs (business portion)
Coworking space or home office expenses
Professional development and courses

If more tax was withheld than you owe, filing Form 1040-NR is the only way to get a refund. Many freelancers leave money on the table by not filing. Learn more about filing your ITIN tax return.

Keep records throughout the year:

Track all income from each platform, save your 1042-S forms, and document business expenses with receipts. Good record keeping makes tax filing faster and maximizes your deductions.
