1. The 5 Mandatory Fields to Verify on Every Form W-8BEN
When reviewing a contractor's Form W-8BEN manually, 40% of submissions contain disqualifying errors. Before approving your first Wise Business or ACH payout, verify these five lines: (1) Line 1: Full legal name matching their passport, (2) Line 2: Country of citizenship (must NOT be USA), (3) Line 3: Permanent residence street address outside the US (cannot be a P.O. Box or US address), (4) Line 6a: Foreign Tax Identifying Number (FTIN, such as Philippine TIN, Indian PAN, Mexican RFC, or Brazilian CPF), and (5) Part III: Hand-signed or IRS-compliant electronic signature with the date and printed name.
Note: Because services performed entirely outside the United States are already exempt from US tax under IRC § 862(a)(3), Part II (Claim of Tax Treaty Benefits) is generally optional for pure remote service contractors, though completing Line 9 (country of tax residence) is best practice.

2. Watch Out for the 'US Citizen Living Abroad' Trap
If you hire a digital nomad living in Bali, Lisbon, or Mexico City who holds a US passport or US Green Card, they are a US Person for worldwide tax purposes—they CANNOT sign Form W-8BEN. You must collect a Form W-9 and issue them an annual Form 1099-NEC, regardless of where they live.
Onboarding platforms like Deel and Oyster HR automatically screen nationality and residency during KYC verification so your finance team never accidentally collects the wrong tax form.

3. How to Automate W-8BEN Collection & 3-Year Renewals in 5 Minutes
Under IRS regulations, a Form W-8BEN signed on any date in 2026 remains valid through December 31, 2029 (the end of the third succeeding calendar year), unless a change in circumstances occurs (such as the contractor moving to the United States).
Instead of maintaining manual Google Drive folders and calendar alerts, US companies use Deel ($49/mo) or Oyster HR ($29/mo) to require digital W-8BEN execution as a hard gate before a contractor's first invoice can be paid, with automated re-certification every 3 years.

Frequently Asked Questions (US Employers & IRS Compliance)
Q. Can foreign contractors sign IRS Form W-8BEN electronically?
Yes. Under Treasury Regulation § 1.1441-1(e)(4)(iv), withholding agents (US companies) may accept electronically signed Forms W-8BEN provided the electronic system authenticates the signer, timestamps the submission, and includes a perjury statement—all of which are built into Deel and Oyster HR.
Q. What if a foreign contractor incorporates a single-member US LLC (e.g., via doola or Stripe Atlas)?
If a foreign non-resident owns a single-member US disregarded LLC, IRS rules require looking through the disregarded entity to the foreign owner: the contractor provides a Form W-8BEN in their individual name (listing the LLC on the reference line), whereas a multi-member US LLC or US C-Corp provides a Form W-9.
