Why most companies do this badly
The default workflow — CFO opens a wire at Chase, accountant pulls a W-9 (which is wrong for foreign payees), and nobody files 1042-S — works for a year or two until the company crosses the threshold that triggers a Form 1042 audit. Once the audit starts, the back-taxes, penalties and required filings can easily exceed the original payment volume. AION's remittance module is built so this doesn't happen.
What we handle
Outbound wires to vendors, contractors, employees and intercompany affiliates in 130+ countries. Currency conversion at institutional FX rates (not retail-bank markups). W-8BEN / W-8BEN-E collection and validation. Treaty-based withholding determinations. Form 1042 and 1042-S preparation. FBAR (FinCEN 114) and Form 8938 tracking for officers with foreign-account authority.
- Wire execution to 130+ countries with same-day settlement where supported
- Institutional FX (typically 25–75 basis points vs retail bank markups of 200–400 bp)
- W-8BEN-E collection, validation and refresh on renewal cycles
- Treaty-based withholding analysis (US-Korea, US-UK, US-Singapore, US-Netherlands, etc.)
- Form 1042 / 1042-S annual reporting with deposit reconciliation
- FBAR / FinCEN 114 tracking for signatory officers
- Real-time payment status in the AION client portal
Korean-corridor specifics
For our Korean-corridor clients, AION's Seoul team handles the Korean-side coordination — KRW/USD execution, NTS reporting on inbound treaty payments, and resident-tax considerations for Korean officers receiving U.S.-source income. This is bilingual, credentialed work, not outsourced.
Compliance you'll appreciate at audit time
Every wire AION executes is accompanied by the W-8 series form for the payee on file, the treaty analysis backing any reduced withholding, the wire confirmation, and the journal entry tying it to your books. When your 1042 audit comes (and it will, eventually), the file is already built.
Pricing and limits
AION's remittance module is offered as part of the Tax & Bookkeeping bundle or as a standalone service. Standalone clients are quoted by volume tier. There is no individual transaction fee for clients on the bundled plan; standalone clients see a flat per-transaction execution fee plus institutional FX, with no hidden conversion markups.
