A VAT return should not be prepared as an isolated form at the end of a filing period. It should come from books that already reconcile sales, purchases, invoices, credit notes, bank receipts and other transaction records.
Before preparing the VAT return
- Complete sales entries for the period.
- Enter eligible purchase invoices and supporting documents.
- Check invoice dates, invoice numbers and taxpayer details.
- Reconcile cash, bank, wallet and credit sales where relevant.
- Review adjustments, returns and credit notes.
Reconcile sales first
Start with the sales ledger, not the VAT form. Compare recorded sales with issued invoices, bank deposits, digital-wallet collections, point-of-sale reports and major customer balances. Differences should be explained before filing.
Review purchases carefully
A purchase being a business expense does not automatically mean every associated amount receives the same VAT treatment. Keep the underlying tax invoice and confirm that the purchase is connected to the business and treated correctly under current rules.
Records that make VAT work easier
Maintain a clear invoice sequence, purchase register, customer and supplier ledgers, bank reconciliation and a folder for tax filings and payment evidence. Consistency reduces the risk of missing transactions and makes audit work easier.
Common VAT filing mistakes
- Filing before the bookkeeping is complete.
- Sales figures that do not reconcile with collections.
- Missing or duplicated purchase invoices.
- Claiming treatment without sufficient supporting documents.
- Using an old threshold or procedural rule.
Frequently asked questions
Should I prepare the VAT return before the books?
No. A better process is to complete and reconcile the books first, then prepare the return from those records.
Can I claim every purchase shown in my bank statement?
No. Bank payment alone does not establish the correct VAT treatment. Review the invoice and applicable rules.
