Free tools for cross-border freelancers

Practical, no-signup calculators and helpers for freelancers working with US clients. Built by the TaxFlow team to make cross-border taxes a little less painful.

  • W-8BEN Withholding Tax Calculator — see exactly how much a missing or expired W-8BEN costs you: compare the default 30% withholding against your country’s tax-treaty rate.
  • W-8BEN Form Checklist — a step-by-step checklist for filling out Form W-8BEN correctly, and avoiding the mistakes that trigger 30% backup withholding.
  • Invoice Generator — create a clean, professional, tax-ready invoice in seconds; multi-currency and downloadable as PDF.

Every tool runs free and without an account. TaxFlow — the full workspace — adds W-8BEN expiry tracking with reminders, invoice scanning (OCR), cloud sync, and a multi-currency dashboard.
