Frequently Asked Questions

Tax Compliance FAQs

Common questions about IntelliTax SA deployment, compliance, and technical architecture.

FAQ-01

What tax types does IntelliTax SA support?

IntelliTax SA supports Corporate Income Tax (ITR14), VAT 201 returns, PAYE and EMP501 reconciliations, Provisional Tax (IRP6), and Customs & Excise duties. Our tax code validation engine covers all major tax types under the South African Income Tax Act, VAT Act, Customs and Excise Act, and Carbon Tax Act.

FAQ-02

How does the SARS eFiling Bridge work?

The SARS eFiling Bridge is a certified API integration layer connecting directly to the SARS eFiling platform. It supports return submissions, payment reference number generation, notice of assessment retrieval, and taxpayer compliance status queries. All communications are encrypted using TLS 1.3 with SARS-issued digital certificates.

FAQ-03

Is IntelliTax SA POPIA compliant?

Yes. IntelliTax SA is fully POPIA compliant. All taxpayer data is processed and stored within South Africa's sovereign infrastructure. The platform implements data minimisation, purpose limitation, and automated data retention policies. All access is logged with full chain-of-custody records.

FAQ-04

How long does deployment take?

Standard cloud deployment is completed within 14 business days, including SARS eFiling Bridge configuration, ERP connector setup, user provisioning, and team training. Enterprise on-premise deployments typically take 4–6 weeks.

FAQ-05

What is the zero-hallucination protocol?

The zero-hallucination protocol (SEE R5) guarantees all system outputs are deterministically derived from verified data sources and tax code logic. No probabilistic AI models are used in tax computation. Every calculation is traceable to a specific legislative provision with full audit trails.

FAQ-06

Can IntelliTax SA handle multi-entity groups?

Yes. Professional and Enterprise plans support multi-entity consolidation with centralised control and decentralised data boundaries. The system supports VAT group registration, transfer pricing documentation, and consolidated CIT assessments with entity-level allocation schedules.
