Tearing up a cancelled invoice and issuing a new one is one of the fastest ways to put your business on ZIMRA's high-risk list.
Tax Article No. 4: Common mistakes in Accounting for cancelled or amended Fiscal Tax Invoices
Section 21, VAT Act provides for mechanism for cancellation or amendment of Fiscal Tax Invoices.
Two statutory documents are used for amendments: A Debit Note and a Credit Note.
A Credit note is issued by a supplier where the amount of supply & VAT charge has to be reduced due to overcharge or a supply has been cancelled or some goods has been returned.
A Debit note is issued where the value of supply and tax charge has to be increased owing to circumstances such as undercharging, or the nature of supply has been amended.
In a nutshell, a debit note increases and a credit note decreases amounts on Invoices.
Here are the common mistakes in Accounting for cancellation or amendments of supply.
1. Not raising a credit or debit note on amendments
Some accountants think they can simply tear the cancelled invoice, issue another and move on.
Implication
With the FDMS in place, every invoice raised remains intact in your FDMS as "valid" — ignoring the invoice is disastrous as it creates mismatch between your FDMS data and your return submission.
2. Properly raising a credit note, or debit note but omit the cancelled invoice in your return
Implications
This again creates a mismatch between fiscal data in FDMS and your tax return submission. All cancelled Invoices should be declared in your return and should be part of your turnover. The credit notes issued will show in your Invoices management module available input Tax claim. So you declare cancelled Invoices and claim input Tax on credit notes.
3. Recipients of Credit notes not Accounting for credit notes received
Some accountants would simply omit cancelled Invoices in their input Tax claim.
Implications
Not accounting for cancelled invoices will result in data mismatch which may attract audits or investigations.
Cancelled Invoices should be claimed and credit notes received declared in output tax adjustments to ensure FDMS data matches with returns.
Conclusion
An issued Fiscal Tax Invoice remain legally valid, adjustments to the invoice should be made via debit and credit notes.
Raising fiscal invoices require diligence and care to avoid unnecessary cancellation and amendments which certainly complicates accounting and moreso put your account as high risk, triggering ZIMRA audits or investigations.
