ZIMRA's Public Notice 18 of 2026 calls on all registered taxpayers to update their master data records on the TaRMS system by 30 April 2026. Accurate and current taxpayer records are essential for ZIMRA to issue assessments, correspondence, and notices to the correct address and contact details, and for the TaRMS system to accurately reflect each taxpayer's registration status and business profile. Outdated records expose taxpayers to the risk of missing critical communications from ZIMRA.
Data Fields to be Updated
Taxpayers are required to review and update the following categories of information where any change has occurred since the record was last confirmed:
| Data Category | Specific Information |
|---|---|
| Legal and Trade Names | Registered company name, trading name (if different), and any name changes following re-registration or restructuring |
| Contact Information | Physical address, postal address, telephone numbers, email addresses, and website (if applicable) |
| Business Activity Classifications | Standard Industrial Classification (SIC) codes reflecting the actual primary and secondary business activities |
| Tax Agent Data | Name, TIN, and licence number of the appointed tax agent (if any); removal of agents no longer engaged |
| Public Officer Details | Name, ID number, and contact details of the designated public officer responsible for tax compliance (applicable to companies and other entities) |
How to Update Records
Most taxpayers (individuals, companies, and other entities) may update their records directly through the TaRMS self-service portal at mytaxselfservice.zimra.co.zw. After logging in, navigate to the Taxpayer Profile section, review each data category, and submit any corrections or additions. Certain changes — such as a change of company name or a change in the nature of a business's primary activity — may require supporting documentation (for example, a certificate of incorporation showing the new name), which can be uploaded through TaRMS or submitted to a ZIMRA office.
ZIMRA has specified that only registered tax agents are required to visit ZIMRA offices to update their own agent registration details. All other taxpayers should complete updates via TaRMS without needing to attend in person, thereby saving time and reducing administrative burden.
Importance of Correct SIC Codes
The Standard Industrial Classification (SIC) code assigned to a taxpayer's profile is used by ZIMRA for risk profiling, statistical analysis, and sector-based compliance monitoring. An incorrect SIC code — whether because the business has changed its primary activity or because the original registration used an approximate classification — can result in the taxpayer being benchmarked against the wrong industry peer group, potentially triggering unnecessary compliance reviews. Taxpayers who have diversified their business activities or changed their primary revenue source since initial registration should ensure that their SIC code accurately reflects their current operations.
Deadline and Consequences of Non-Update
All updates must be completed by 30 April 2026. Taxpayers who fail to update their records by this deadline risk:
- Receiving ZIMRA correspondence (assessments, audit notifications, refund approvals) at an incorrect address, which does not suspend the legal effectiveness of such notices;
- Missing TaRMS system notifications related to their tax account;
- Being flagged as non-responsive in ZIMRA's compliance monitoring system; and
- Potential delays in the processing of VAT refunds or other claims that require verified taxpayer identity information.
Deadline: 30 April 2026. All registered taxpayers must update their legal/trade names, contact details, SIC codes, tax agent records, and public officer details on TaRMS by this date. Most updates can be completed online via the TaRMS Self-Service Portal. Only registered tax agents need to visit a ZIMRA office for agent-specific updates.
