Receipts vs Invoices for Tax Records
Receipts and invoices are often confused, but for tax purposes they prove different things: an invoice shows what was owed, a receipt shows what was paid. You generally need both. Here is how each works in your tax records.
What Each Document Proves
An invoice is a demand for payment issued before (or at the time of) the transaction — it details what was sold, the amounts, tax charged, and payment terms. A receipt is issued after payment, confirming the amount received, the date, the payment method, and which invoice it settles. For your sales, invoices prove revenue; receipts prove collection.
For your purchases (expenses), the supplier's invoice or receipt is your evidence for deductions and input tax credits. Tax authorities generally want the supplier's tax invoice specifically — a card slip alone often lacks the required details like the supplier's tax number and tax breakdown.
Which One Tax Authorities Require
For claiming VAT/GST input credits or business expense deductions, you need a valid tax invoice from the supplier showing their tax registration number, the tax charged, and the other required fields. A simple payment receipt without these details may not support the claim — this is why 'please send a proper tax invoice' is a common request to suppliers.
For your own sales records, keep both the invoices you issued and proof of payment (bank records, receipt copies). Under cash accounting the payment proof determines the tax year; under accrual accounting the invoice does. Either way, the pair tells the complete story.
Issuing Receipts to Customers
Issue a receipt whenever a customer pays — automatically for online payments, and on request (or as policy) for bank transfers and cash. A good receipt shows your business details, the receipt number and date, the customer's name, the amount paid, the payment method, and the invoice number(s) it covers.
For cash payments, receipts are essential — without one, disputes about whether payment was made are word-against-word. Number receipts sequentially like invoices and store them with the settled invoice.
Keeping Both Audit-Ready
File receipts with their invoices: each invoice folder (physical or digital) should end up containing the invoice, the payment receipt or bank record, and any credit notes. An auditor picking any invoice should be able to trace it to payment in under a minute.
For small cash expenses without invoices (parking, tips), keep a contemporaneous log with date, amount, and business purpose — many jurisdictions allow reasonable small expenses with a log, but invented-at-tax-time lists do not survive scrutiny. When in doubt, get the invoice.
Frequently asked questions
Can I claim a tax deduction with just a receipt?
Sometimes, but a proper tax invoice is stronger and often required — especially for VAT/GST input credits, which generally need the supplier's tax number and tax breakdown shown on a tax invoice. Always request a tax invoice for significant purchases.
Do I need to issue receipts if I already sent invoices?
It is good practice and often expected, particularly for cash and in-person payments. At minimum, send payment confirmations referencing the invoice number — it prevents 'I already paid' disputes.
What is the difference between a receipt and a paid invoice?
A paid invoice is an invoice marked as paid; a receipt is a separate document confirming payment received. Functionally similar, but receipts carry payment-specific details (method, date received, receipt number) that a marked invoice may lack.
