On 13 October 2026, the Zambia Revenue Authority (ZRA) commenced a structured engagement with major business associations, including the Zambia Chamber of Commerce and Industry (ZACCI) and the Zambia Association of Manufacturers (ZAM), to discuss the migration of taxpayer data onto a new integrated tax administration platform. This initiative follows the enactment of the Tax Administration Amendment Act 2025, which mandates the modernization of tax records management and real-time compliance monitoring. The consultation aims to align system specifications with private-sector operational realities, ensuring minimal disruption during the transition scheduled for 1 January 2027. The new platform, known as the Integrated Tax Administration System (ITAS), will consolidate taxpayer registration, return filing, payment processing, and audit case management into a single digital interface, replacing the legacy TaxOnline system that has been in operation since 2014.
Key Takeaways
- Phased Migration Schedule: The ZRA outlined a three-phase migration plan starting with large taxpayers (annual turnover above ZMW 100 million) in Q1 2027, followed by medium enterprises (turnover ZMW 10–100 million) in Q2, and small taxpayers (turnover below ZMW 10 million) by Q4 2027. Each phase includes a 60-day parallel run period where both legacy and new systems operate concurrently to validate data integrity. Taxpayers must submit a migration readiness declaration 30 days before their designated phase.
- Data Validation and Dispute Resolution: Taxpayers will be granted a 30-day window post-migration to verify migrated data accuracy against their own records. The ZRA has established a dedicated dispute resolution desk to address discrepancies, with decisions appealable to the Tax Appeals Tribunal within 21 days. The authority has also committed to publishing a data migration audit trail for transparency.
- Compliance Incentives and Penalties: Early adopters who complete migration ahead of their designated phase will receive a 2% reduction in provisional tax installments for the 2027 tax year. Conversely, non-compliant entities face a penalty of 5,000 penalty units (approximately ZMW 250,000) per month of delay under Section 84 of the Tax Administration Act. The ZRA also announced that failure to migrate by the final deadline will result in automatic suspension of tax clearance certificates.
- Technical Requirements and Support: The ITAS platform requires taxpayers to adopt standardized electronic invoicing (e-invoicing) compatible with the ZRA’s Smart Invoice specifications. The ZRA will provide free API integration tools and a sandbox environment for testing from 1 November 2026. Dedicated support teams will be deployed to provincial offices to assist with onboarding.
