We handle your side.

The Problem
When your organization pays a foreign vendor, the IRS treats you as the withholding agent.
You are responsible for collecting a valid W-8, applying the correct treaty rate, withholding the right amount, and reporting it every year on Form 1042 and 1042-S. Most accounts payable teams were never trained for this. Forms come in wrong, treaty claims go unverified, and the exposure sits with the payer, not the vendor.
What We Do
What TaxJet does
W-8 collection and validation.
We confirm each vendor filed the right form (W-8BEN, W-8BEN-E, and the less common variants) and that it is complete and current.
Treaty determination.
We identify the correct withholding rate for each vendor and income type, and document why.
Withholding support.
We give your AP team the exact rate to apply before payment goes out.
Form 1042 and 1042-S.
When an engagement calls for it, we prepare your annual withholding return and the 1042-S statements, or work alongside the team that files them. Scoped case by case.
Clean-up and review.
If your documentation is behind, we review what you have and tell you what is missing.
Credibility
Why TaxJet
TaxJet specializes in cross-border tax. Its founder, Renee Mizrahi, EA, served as Unit Chief of Tax Reporting at the New York City Comptroller’s Office, where she managed W-8 and 1042 collection and filing for the individuals and businesses that contracted with the city.
