Tax Document Gathering for International Tax Specialists with ONESOURCE
Run tax document gathering on autopilot inside ONESOURCE.
The Problem
Chasing Cross-Border Tax clients for 1099s, K-1s, brokerage statements, and receipts consumes the first three weeks of every filing season — and the slowest 10% of clients create 80% of the deadline risk.
What We Build in ONESOURCE
AI monitors ONESOURCE and the client portal, auto-classifies incoming documents, flags what's missing against the prior-year return, and sends personalized nudges on a cadence — reducing document-gathering time by 65%. Purpose-built for teams running ONESOURCE — uses the native API or agent integration so nothing leaves the system of record.

Human-in-the-loop handoff
Every automation routes exceptions back to a human in ONESOURCE with enough context to act — AI handles the 80%, your team owns the judgment calls.
Frequently asked
Does this tax document gathering automation work natively in ONESOURCE?+
Yes — we build directly on ONESOURCE's API or agent integration. Your data stays in ONESOURCE, your international tax specialists keep the same login and UI, and there's no parallel system for the team to learn.
What ONESOURCE configuration do we need before deployment?+
We work with your existing ONESOURCE setup. During discovery we map the specific objects, custom fields, and workflows the automation touches — no rip-and-replace required for cross-border tax teams.
Can ONESOURCE handle tax document gathering on its own?+
ONESOURCE handles configuration; AI handles judgment. Native ONESOURCE workflows route deterministic tasks; our automation layer adds the AI judgment ONESOURCE doesn't ship out of the box — document classification, exception triage, drafting.

ONESOURCE is widely used among cross-border tax teams precisely because of its data model around tax document gathering. We've deployed this workflow on ONESOURCE for similar firms and the integration is well-trodden.
What's the typical ROI of tax document gathering automation in ONESOURCE?+
For cross-border tax firms running ONESOURCE, automation typically pays back inside the first quarter — measured against the loaded cost of the international tax specialist hours absorbed. Higher volumes deploy faster.
