Tax Notice & Agency Correspondence for International Tax Specialists with ONESOURCE

ONESOURCE International Tax Specialist Cross-Border Tax

The Problem

IRS and state notices arrive for Cross-Border Tax clients with 30-day deadlines and cryptic codes — and the partner doesn't see them until the team finally surfaces the mail pile.

What We Build in ONESOURCE

AI classifies every incoming notice, links it to the client file in ONESOURCE, drafts the response, and calendars the deadline — no notice slips past a response window. Purpose-built for teams running ONESOURCE — uses the native API or agent integration so nothing leaves the system of record.

ONESOURCE Integration Approach

1

Audit your ONESOURCE configuration

We map the specific ONESOURCE objects, custom fields, and workflows the automation needs to touch for your cross-border tax practice.

2

Build on the ONESOURCE API or agent

Integration happens inside ONESOURCE — no data leaves the system, no parallel tool for your team to learn, no license changes.

3

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.
