Context

Eswatini's Revenue Service (ERS) faces an estimated annual tax leakage of E4.259 billion, with VAT collected from consumers not always reaching the treasury.

Activities

In May 2026 ERS launched TaxCore, real-time e-invoicing built by Data Tech International; in July 2026 it announced a 12-month 'compliance by default' plan piloting AI models to flag high-risk returns, with human staff retaining audit sign-off; in August 2026 ERS partnered with the University of Eswatini's AI Academy on an AI Literacy Programme for staff.

Results

ERS's broader digitalisation drive coincided with a rising tax-to-GDP ratio, higher voluntary compliance, an improved client Net Promoter Score and a lower cost-to-revenue ratio, though none of these figures isolates the AI pilot's own contribution.

Implementation
Indicative cost
Medium (€50k–€500k) — TaxCore e-invoicing platform procurement plus an AI pilot and UNESWA AI Literacy Programme partnership; costs not publicly itemised.
Time to results
