Tax Due Diligence Agent
The agent analyses group structures, transfer pricing arrangements, SARS correspondence and tax returns to identify permanent establishment risk, intercompany issues and compliance gaps. It delivers a cited tax risk assessment under the Income Tax Act and relevant double tax agreements, ready for your legal and finance teams.

The difference
From 3-4 weeks to 2-3 days
Your tax advisers deliver findings within the deal timetable and spend their time quantifying and structuring around risk rather than reading files.

Indicative figures. We measure your own baseline in the first fortnight so the numbers you see are yours.
Hidden exposures found early
Transfer pricing gaps, s23M limits, CFC positions and prior s45 or s47 restructurings are surfaced before they become price chips or post-deal liabilities.
Returns tested against the books
ITR14s, IRP6s, VAT201s and PAYE returns are cross-referenced with the financial statements and Tax Compliance Status to reveal inconsistencies.
Stronger negotiating position
Every risk is cited to source, giving your team the evidence it needs for warranties, indemnities and price adjustments.
Capabilities
Surface transfer pricing, structure and compliance exposures before you sign.
Built for M&A tax advisers, PE deal teams, and corporate development and legal teams on SA and cross-border transactions.
Permanent establishment detection
Analyses entity structures, operational footprints and contracts to identify where a foreign company may have a PE in SA, or an SA group abroad, under the relevant double tax agreement.
Transfer pricing analysis
Reviews intercompany pricing against s31, SARS Practice Note 7 and Interpretation Note 127, flagging missing master file or local file documentation and secondary adjustment exposure.
Entity structure mapping
Maps ownership hierarchies from CIPC records, share registers and beneficial ownership registers, highlighting CFCs under s9D and prior s45 or s47 restructurings.
Compliance verification
Cross-references financial statements with ITR14s, IRP6s, VAT201s, PAYE returns, SARS assessments and the Tax Compliance Status to surface gaps.
Related-party transaction identification
Detects undisclosed or poorly documented connected-person transactions and debt that could trigger s31 adjustments, s23M limits or penalties.
Audit trail and documentation
Provides a cited analysis of every risk with links to source documents, supporting warranties, indemnities and price negotiations.

In the frontier assistant you already pay for
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.

How we deliver it
One agent, three ways to hold it
Start where your team already works, then take it as far into your systems as the value justifies.
DATA SECURITY & PRIVACY
Your tax files stay yours.
The agent runs inside your tenancy, reads only what each task needs, and never trains on your tax files. Every step is logged so your auditors can see exactly what it touched.
Built for regulated work.
