Why a Bad Supplier Invoice Can Cost You Money
Published · Last checked 18 October 2026 · 4 min read
In 2026 a careless supplier can cost you real money. If their invoice is not valid on ZIMRA's system, you cannot claim back the VAT you paid them. You still paid it; you just cannot recover it. Here is how the new input tax claim rule works and how to protect yourself.
Input tax in one minute
When you buy stock or services for your business, you pay VAT to your supplier. That is your input tax. When you sell, you charge VAT to your customers. That is your output tax. Each month or period, you pay ZIMRA the difference.
The input tax you can claim directly lowers your VAT bill. Every claim you lose is money out of your pocket.
What changed in 2026
- No more manual input tax schedules for tax periods from 1 January 2026, unless the Commissioner approves.
- Your claimable invoices are pulled automatically from FDMS into TaRMS, under its Invoice Management Module.
- Only invoices that show Valid on the FDMS validation portal, with your correct details as buyer, are considered.
This is a matching system. If your supplier never sent the invoice to ZIMRA, or sent it with your wrong TIN, it does not exist for your return.
What a bad invoice costs
Say you buy US$10,000 of stock, before VAT. At 15.5%, the VAT is US$1,550.
| Supplier's invoice | Input VAT you can claim | Your loss |
|---|---|---|
| Valid on FDMS, your details correct | US$1,550 | US$0 |
| Not sent to FDMS | US$0 | US$1,550 |
| Sent, but your TIN is wrong | Not considered until corrected | US$1,550 at risk |
There is a second risk. ZIMRA has warned that invoices which are not compliant cannot support income tax expense claims either.
Protect your claims: a supplier checklist
- Send every supplier your exact business name, address, TIN and VAT number in writing.
- Ask new suppliers whether they fiscalise through FDMS before your first order.
- Scan the QR code on large invoices when they arrive. It should say Valid.
- Before each VAT return, open TaRMS and check that the invoices you expect are listed.
- Chase missing or wrong invoices early, not on deadline day.
- For suppliers who keep failing, add the lost VAT to their real price, or switch.
Example: a hardware store in Mutare
A hardware store buys cement every week from three suppliers. Two fiscalise properly. The third prints neat invoices that never reach FDMS. Over a quarter, the store buys US$18,000 from that supplier before VAT. The lost input VAT is US$2,790. The "cheap" supplier was 15.5% more expensive than it looked.

Frequently asked questions
Can I claim input tax on an invoice from a non-VAT-registered supplier?
No. Only VAT-registered suppliers charge VAT, so there is no input tax to claim.
What if the supplier fixes the invoice after I file?
Ask ZIMRA or your tax practitioner how to claim it in a later period. Keep a record of the correction.
Does this apply to Category B taxpayers too?
Yes. ZIMRA's TaRMS/FDMS integration notice says Category B taxpayers claim input tax on valid fiscal tax invoices as well.
