Practical Experience:
We are assisting clients with their SARS GMT XML submissions.
This experience informs how we help teams move from prepared calculations through validation, XML creation, review, and submission, while retaining the controls needed for future cycles.
Who This Is For
For South African-headquartered multinational groups that already have calculations, but need confidence in the final mile
This is designed for groups that operate in multiple jurisdictions, exceed the EUR 750 million threshold, and want a cleaner route from existing calculations to a submission-ready SARS XML output.
Existing calculations, limited assurance
Teams have already done much of the hard work, but still need comfort that the final position reflects the GloBE rules consistently.
Manual spreadsheets at the submission stage
Spreadsheet-heavy workflows create risk when moving from Safe Harbour reviews and elections into GIR and XML output.
One-off filing fixes do not scale
The immediate pressure may be submission, but the lasting issue is managing group changes, prior year adjustments, and future filings in a repeatable way.
How It Works
A software-led process with the GloBE rules built in
Rather than asking teams to start again, TaxPacc Pillar Two validates existing calculations and automates the next steps through to GIR and SARS XML creation.
Upload in bulk
Entity and financial information is uploaded in bulk so teams can move quickly without rebuilding the data set manually.
Apply the GloBE logic
Safe Harbours are applied automatically. Entities that do not qualify can move into De Minimis or a detailed GloBE calculation path.
Manage elections and tax allocation
Entity and jurisdictional elections are captured in a controlled way, with top-up tax calculated and allocated to parent entities automatically.
Generate GIR and SARS XML
Once the calculation position is validated, TaxPacc Pillar Two produces a submission-ready output for internal sign-off and SARS filing.
FAQs
Questions you are likely thinking now
Can TaxPacc Pillar Two work with calculations we have already prepared?
Yes. A core TaxPacc Pillar Two use case is validating your existing Pillar Two or GMT calculations rather than forcing teams to restart the process.
Does it only create SARS XML, or does it also support the wider calculation workflow?
It does both. TaxPacc Pillar Two validates calculations, applies the GloBE rules, manages elections, calculates allocations, and generates GIR and SARS XML outputs.
What happens if entities do not meet the Safe Harbour requirements?
The workflow supports De Minimis elections where relevant, or moves those entities into a detailed GloBE calculation path.
Do you have practical SARS GMT XML submission experience?
Yes. We are assisting clients with their SARS GMT XML submissions, and this practical experience informs our validation, XML, review, and workflow support.
Is this only for the current filing cycle?
No. It is designed to support future cycles through roll-forward capability, group structure tracking, and prior year adjustment management.
