AI agent for tax analysts
Withholding Tax Treaty Check Agent
Each cross-border payment has the correct withholding rate backed by valid forms.
What it does
Cross-border payments need the right withholding rate, and a treaty rate applies only if the recipient has a valid form on file. Mistakes mean over-withholding or tax owed later. This agent reads each payment, checks the recipient's country, the forms on file and the treaty rate, and flags missing or expired forms. It requests them and recomputes. The analyst approves payment release. It decides by the payment type, the country and whether a valid form supports the reduced rate. Edge case: a form is on file but expired, so the agent applies the default rate until a new one arrives.
How it works
Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

- Is a valid form on file for each reduced rate?If not: request the form and apply the default rate. Back to step 2.

- Analyst approves payment releaseThe agent waits here for your OK.

How it decides
