Cross-Border Tax Compliance Agent
The Cross-Border Tax Compliance Agent analyses intercompany agreements, invoices and transaction records against South African transfer pricing, withholding tax and permanent establishment rules. It flags non-compliant items and records a clear audit trail, so your tax team can focus on strategy rather than checking.

Indicative figures. We measure your own baseline in the first fortnight so the numbers you see are yours.
One review across every tax
Cross-border flows touch section 31, section 23M, withholding taxes, dividends tax, treaties and VAT on imported services at once. The agent checks them together instead of in separate spreadsheets.
Quarterly effort cut to hours
Reviewing intercompany and foreign supplier transactions every quarter consumes weeks of senior time. The agent does the heavy lifting and hands your team the exceptions.
Ready for SARS questions
Every flagged item links to the relevant provision and source document, so you can answer SARS queries and audits quickly and consistently.
Capabilities
Catch transfer pricing, withholding and PE risks before they become SARS findings.
Built for group tax teams in South African multinationals and inbound subsidiaries, and the transfer pricing advisers who support them.
Multi-jurisdiction regulatory checking
Verifies transactions against SA VAT (including imported services), transfer pricing, permanent establishment and double tax agreement rules, alongside the local rules of your other operating countries.
Cross-border invoice validation
Checks intercompany and foreign supplier invoices for tax numbers, correct VAT treatment and the documentation needed to support deductions and any reverse charge on the VAT201.
Transfer pricing risk detection
Identifies intercompany transactions that may attract section 31 scrutiny, flags unusual pricing and connected-party debt affected by section 23M, and checks that master and local files match actual flows.
Contract and withholding analysis
Reviews contracts for withholding tax on royalties, interest and service fees to non-residents, dividends tax, change-of-control provisions and terms that could create a PE or affect treaty relief.
Audit trail and documentation
Records every check, linking each flagged item to the relevant provision and source document, ready for SARS queries or audit.
Continuous regulatory updates
Your knowledge base can be updated with new SARS guidance, OECD Transfer Pricing Guidelines and treaty changes, so the agent always applies current rules.

We publish the agent as an MCP server. Add it as a connector and your team calls it from the chat they use every day, with no new tool to learn.
