How ZIMRA's TaRMS–FDMS Integration Changes Your VAT Workflow

What changed

ZIMRA runs two systems that now work as one. FDMS (the Fiscalisation Data Management System) receives every fiscal tax invoice at the time of sale. TaRMS (the Tax and Revenue Management System) is where VAT returns are filed. The integration feeds the first into the second.

16 April 2025: the upgraded TaRMS VAT module introduced an automatic input tax schedule built from fiscal tax invoices, plus automatic credit and debit note management (Public Notice 7 of 2025).
31 May 2025: deadline for fiscal devices to transmit buyer details: name, address, TIN, contact details and VAT number where applicable (Public Notice 30 of 2025).
1 December 2025: invoice management functions of the full TaRMS–FDMS integration went live (Public Notice 63 of 2025).
1 January 2026: the standard VAT rate moved from 15% to 15.5% (LookupTax, citing ZIMRA Public Notice 7 of 2026).
10 January 2026 onwards: VAT return submission upgrades under the integration (Public Notice 63 of 2025).

Why this matters

Before the integration, claiming input tax meant matching supplier invoices against your records by hand. It was slow and error-prone, and it created reconciliation bottlenecks every VAT period. Now the input tax schedule is built from the fiscal data your suppliers transmit, and you select what to claim from it.

The work moves from typing in invoices to checking a schedule ZIMRA has already built. If a supplier's invoices are missing from it, that is now your problem to chase.

How does the TaRMS–FDMS integration affect my VAT return?

ZIMRA's TaRMS system now builds your input tax schedule automatically from fiscal tax invoices, credit notes and debit notes that your suppliers transmit through FDMS, ZIMRA's fiscalisation system. This started on 16 April 2025 under Public Notice 7 of 2025, and the full integration rolled out from 1 December 2025, with upgraded VAT returns from 10 January 2026, under Public Notice 63 of 2025. You review, select and claim from that schedule instead of matching supplier invoices by hand.

How it works, in three steps

Supplier transmission. Your suppliers issue fiscal tax invoices with your details as buyer: name, address, TIN, contact details and VAT number.
Data flows into TaRMS. ZIMRA passes the fiscal invoice data into TaRMS, where it appears in your input tax schedule.
You review and claim. You check the schedule against your purchase ledger, select what to claim for the period and file your return.

Cut-offs you need to know

ZIMRA set hard cut-offs as each stage went live. Valid fiscal tax invoices, debit notes received and credit notes issued up to 30 November 2025 had to be claimed on or before 10 December 2025; ZIMRA stated it would not be able to process them for input tax in the new system after that (Public Notice 63 of 2025). The same notice ties tax clearance to fiscalisation compliance.

Can I still claim input tax on old fiscal tax invoices?

Only within ZIMRA's cut-offs. Under Public Notice 63 of 2025, valid fiscal tax invoices, debit notes received and credit notes issued up to 30 November 2025 had to be claimed on or before 10 December 2025; ZIMRA stated it would not be able to receive or process them for input tax in the new system after that. An earlier cut-off under Public Notice 7 of 2025 applied to invoices issued before 31 March 2025.

What to check now

Your input tax schedule. Log in to TaRMS and confirm that supplier invoices are appearing. Gaps usually mean a supplier is not fiscalising, or your details on their invoices are wrong.
Your details on supplier invoices. Give every supplier your exact registered name, TIN and VAT number. If they are wrong on the invoice, the invoice will not land where it should.
Your own invoices. Your VAT-registered customers rely on your fiscal invoices the same way. Buyer details have been mandatory since 31 May 2025.
The VAT rate on your invoices. The standard rate has been 15.5% since 1 January 2026.

The bigger picture

ZIMRA now has invoice-level data from the moment of sale through to the VAT return. That brings real benefits: faster returns, fewer manual entries and an audit trail that builds itself. It also means a fiscalisation gap now shows up in your VAT return and in your customers' returns. Getting fiscalisation right is part of getting VAT right.
