You are preparing your corporate tax return when your accountant asks for the receipt for a $4,800 business purchase.

You know the expense was real.

You can see the payment on the company credit card.

The equipment is sitting in your office.

But the receipt is gone.

Then you find another missing receipt.

And another.

Now the question becomes uncomfortable:

Can CRA deny a legitimate business expense simply because you lost the receipt?

Potentially, yes.

CRA requires businesses to keep records that support income and expense claims. CRA specifically warns that expenses may be disallowed when a taxpayer cannot support them.

But losing one receipt does not automatically mean you should give up on the deduction.

A receipt is important evidence, but CRA’s definition of business records is much broader. Records can include invoices, agreements, bank statements, cancelled cheques, credit-card receipts, contracts, delivery slips, work orders, emails and other correspondence supporting a transaction.

The real issue is whether you can build a reliable audit trail showing:

What was purchased, who sold it, how much was paid, when it was purchased, and why it relates to the business.

This guide explains what to do when business receipts are missing, what supporting evidence can help, when bank statements may not be enough, how GST/HST claims are different, and when CRA could deny an expense.

Important: This article provides general Canadian tax information only. Whether a particular expense or input tax credit is allowed depends on the facts, documentation and applicable legislation.

What Does CRA Actually Require for a Business Expense?

A deductible business expense generally needs two things:

1. It must relate to earning business income.
2. You need records that support the claim.

CRA says a business expense is generally a cost incurred for the purpose of earning business income, and expense claims must be supported by documentation such as an invoice, receipt, purchase agreement or another voucher supporting the expenditure.

CRA’s record-keeping rules are broader than many owners realize.

Supporting records can include:

• Purchase invoices
• Receipts
• Credit-card receipts
• Bank statements
• Cancelled cheques
• Contracts
• Delivery slips
• Work orders
• Statements of account
• Emails
• Correspondence
• Electronic records

CRA requires records to be reliable, complete and supported by documents.

This means the question is not simply:

“Do I have the original paper receipt?”

The better question is:

“Do my records provide enough reliable evidence to establish the transaction?”

What Information Should a Business Receipt Show?

CRA’s current business-record guidance says an expense receipt should show information including:

• Date of purchase
• Seller or supplier’s name and address
• Buyer’s name and address
• Full description of the goods or services
• Vendor’s business number when applicable for GST/HST purposes on purchases of $100 or more before tax

If a normal cash-register receipt does not adequately describe the purchase, CRA recommends adding a description on the receipt, another voucher, or in the expense journal.

These details help explain why a simple bank statement may not always solve the problem.

Problem 1: “I Have the Credit-Card Statement, So That Should Be Enough”

Not necessarily.

Suppose your corporate Visa statement shows:

ABC Supplies: $2,460

That proves that $2,460 was charged to the card.

But what was purchased?

Office equipment?

Personal furniture?

Inventory?

A gift?

A deposit?

A capital asset?

The statement may not answer those questions.

CRA can review bank statements and credit-card information during an audit, but its record-keeping requirements also expect supporting source documents that explain the transaction.

The Solution

Use the credit-card or bank statement as one piece of evidence.

Then try to reconstruct the transaction with:

• Duplicate supplier invoice
• Order confirmation
• Email receipt
• Purchase agreement
• Delivery confirmation
• Supplier account statement
• Warranty registration
• Internal purchase order
• Relevant email conversation

The stronger the documentation package, the easier it is to explain the expense.

Problem 2: You Lost the Receipt but the Supplier Still Has It

This is usually the easiest problem to fix.

Contact the supplier.

Many businesses can reproduce invoices from their:

• Accounting software
• Ecommerce platform
• Customer portal
• Point-of-sale system
• Email system

For major purchases, do this before filing the tax return rather than waiting for CRA to ask.

Example

Your corporation purchased a computer for:

$3,200

The paper receipt is missing.

But you have:

• Credit-card transaction
• Supplier email confirmation
• PDF invoice
• Serial number
• Delivery confirmation

That is a substantially stronger record than a credit-card statement alone.

Problem 3: The Supplier Never Gave You a Receipt

CRA specifically addresses this situation.

If the seller or supplier did not provide a receipt, CRA says you should record:

• Name and address of the seller
• Amount paid
• Date of payment
• Details of the transaction

in your expense journal.

That does not mean businesses should intentionally operate without receipts.

But it shows why maintaining a detailed expense journal matters.

Better Practice

Immediately record:

Date: September 4, 2026
Supplier: XYZ Maintenance
Amount: $275
Purpose: Emergency repair to warehouse loading door
Payment method: Corporate Visa
Requested receipt: Supplier did not issue formal invoice

Then retain any related:

• Text messages
• Emails
• Bank or credit-card evidence
• Work order
• Photos where relevant

The contemporaneous record is much stronger than trying to remember the transaction four years later.

Problem 4: You Lost Hundreds of Receipts

One lost receipt is a documentation problem.

Hundreds of missing receipts may indicate a bookkeeping-control problem.

If your general ledger contains large amounts of expenses but supporting documents are consistently unavailable, an auditor may have much more difficulty verifying the claims.

CRA says records must be reliable and complete, and unsupported claims can be disallowed. If CRA cannot determine figures from incomplete records, it may use other verification methods.

The Solution

Do not wait until an audit.

Reconstruct your records systematically.

Export the year’s transactions from:

• Business bank accounts
• Corporate credit cards
• PayPal or payment platforms
• Vendor accounts
• Ecommerce platforms
• Accounting software

Then match each significant transaction to supporting documents.

This is also a warning that your company may have outgrown a casual bookkeeping process. Aterna’s Signs Your Business Has Outgrown Basic Bookkeeping explains how increasing transaction volume and tax complexity create the need for stronger accounting controls.

What May Help Support an Expense When the Original Receipt Is Missing?

There is no universal substitute that CRA guarantees will automatically be accepted for every expense.

However, CRA recognizes many forms of records and source documents.

A reconstruction might include:

Evidence	What It Helps Establish
Bank statement	That money left the account
Credit-card statement	Merchant, date and amount
Duplicate invoice	What was purchased
Contract	Business purpose and terms
Supplier statement	Amount owing or paid
Cancelled cheque	Payment
Email correspondence	Nature of transaction
Delivery slip	Goods received
Work order	Services performed
Purchase order	Business authorization
Electronic confirmation	Transaction details
Expense journal	Internal explanation

CRA specifically identifies bank statements, credit-card receipts, contracts, delivery slips, work orders and correspondence among the types of records that can support business transactions.

The goal is to create an audit trail.

CRA describes an audit trail as information that allows a business transaction to be reconstructed from supporting documents through to the summarized accounting records.

A Bank Statement Proves Payment, Not Necessarily Deductibility

This distinction is important.

Suppose your business bank statement shows:

Best Buy: $4,000

The payment occurred.

But CRA may still need to know:

• What was purchased?
• Who used it?
• Was it for the business?
• Was it equipment or a current expense?
• Was any portion personal?
• Should it have been capitalized?

This is why the business owner should not think:

“It’s on the corporate card, so CRA has to allow it.”

Payment evidence and tax deductibility are separate questions.

For equipment purchases, this distinction becomes especially important because the cost may need to be capitalized instead of deducted immediately.

Internal link: Your Business Bought Equipment, Vehicles or Technology: Expense It Now or Capitalize It?

When Could CRA Deny the Expense?

An expense may be vulnerable when you cannot adequately establish:

1. That the transaction occurred

There is no receipt, invoice, statement, payment record or other credible evidence.

2. What was purchased

A bank transaction shows $2,000 went to a retailer, but there is no evidence identifying the goods or services.

3. The business purpose

The transaction may have occurred, but there is no evidence showing why the company incurred it to earn business income.

4. Who actually paid

The documentation cannot establish whether the corporation, shareholder, employee or another entity incurred the cost.

5. The amount

The claimed expense does not reconcile with available records.

6. The transaction belongs to another period

The company claims an expense in the wrong fiscal year.

7. It was actually personal

Corporate funds were used, but the purchase benefited the shareholder personally rather than the business.

CRA expressly warns that expenses may be disallowed when taxpayers cannot support them.

Example: Strong Reconstruction vs Weak Reconstruction

Imagine two corporations each claim a:

$7,500 consulting expense

Both have lost the original invoice.

Business A

Business A provides:

• Bank transfer showing $7,500 payment
• Signed consulting agreement
• Emails discussing the work
• Consultant’s statement confirming the invoice
• Final report produced by the consultant
• General ledger entry

Business B

Business B provides:

• One bank withdrawal for $7,500
• Owner says, “I’m pretty sure it was consulting.”

The tax claim is the same.

The quality of evidence is very different.

That is why reconstructing the full transaction is more useful than simply printing a bank statement.

GST/HST Creates a Separate Documentation Problem

This is where missing receipts can become more expensive.

A business expense deduction for income tax and an Input Tax Credit, or ITC, for GST/HST are separate claims.

To claim an ITC, GST/HST registrants need supporting documentation containing prescribed information.

CRA says purchase invoices, receipts, contracts or other business papers must contain specific information supporting the ITC claim.

The required information increases with the size of the transaction.

CRA’s current thresholds are:

• Under $100
• $100 to $499.99
• $500 or more

For larger purchases, more detailed information is required.

Why This Matters

Suppose your company paid:

$5,650

for professional services, including HST.

Your corporate credit-card statement shows the $5,650 payment.

But there is no invoice and no document identifying:

• Supplier’s GST/HST registration information
• Tax charged
• Recipient
• Services provided

You may have a much weaker ITC claim even though you can prove money was paid.

CRA states that ITCs generally cannot be claimed without sufficient documentation establishing eligibility and the amount of the credit.

Practical Rule

When a receipt is missing, reconstruct:

Income-tax support

and

GST/HST support

separately.

Do not assume proof sufficient for one automatically satisfies the other.

Can CRA Accept Digital Receipts?

Yes.

CRA accepts records maintained in accessible and readable electronic formats and permits paper documents to be converted and stored using acceptable electronic imaging processes.

That means you do not necessarily need filing cabinets full of fading paper receipts.

Businesses can maintain:

• PDFs
• Scanned receipts
• Digital invoices
• Electronic statements
• Accounting-system attachments

provided records meet CRA’s requirements and remain accessible.

Better System

When an expense occurs:

1. Photograph or scan the receipt.
2. Attach it to the transaction in the accounting software.
3. Add a short business-purpose description.
4. Back up the electronic records.

CRA also recommends maintaining backups of electronic business information so records remain accessible if originals are lost or deleted.

How Long Should You Keep Business Receipts?

CRA generally requires business records to be kept for at least six years from the end of the last tax year to which they relate.

That means a receipt is not finished with once the tax return has been filed.

CRA may review the return later.

Keep the documents organized and retrievable.

Do not rely on:

• Paper receipts thrown into boxes
• Employee inboxes
• Personal phones
• Temporary download folders
• Vendor websites that may later remove old invoices

The company’s record-retention system should belong to the company.

What If the Employee Lost the Receipt?

This is common with:

• Meals
• Parking
• Travel
• Small supplies
• Taxis
• Emergency purchases

Create a missing-receipt procedure.

The employee should provide a written record including:

• Date
• Supplier
• Amount
• Description
• Business reason
• People involved where relevant
• Payment method
• Reason the original document is unavailable

Attach whatever secondary evidence exists.

For example:

Missing Receipt Declaration

Date: June 12, 2026
Vendor: Downtown Parking
Amount: $38
Purpose: Parking during client meeting
Paid using: Corporate Visa ending 1234
Reason receipt missing: Paper ticket lost
Supporting evidence: Credit-card transaction and calendar meeting record

This is much better than allowing employees to submit unexplained numbers months later.

It does not guarantee CRA acceptance, but it strengthens the audit trail.

What If the Expense Was Paid in Cash?

Cash transactions deserve particular attention because a bank or credit-card trail may not exist.

CRA advises businesses paying cash to obtain receipts or other vouchers. If a supplier does not provide a receipt, CRA says to record the supplier’s details, amount, payment date and transaction details in the expense journal.

Weak Record

Cash expense: $850

Better Record

September 2, 2026
ABC Emergency Plumbing
$850 cash
Emergency repair to broken pipe at warehouse
Technician: John Smith
Work completed between 4:00 p.m. and 7:00 p.m.
Supporting text-message conversation retained

The second record gives someone reviewing the transaction years later a much clearer explanation.

What If CRA Is Already Auditing You?

Do not start creating fake receipts.

Do not alter old documents.

Do not invent supplier invoices.

Instead, identify exactly what documentation is missing and reconstruct the transaction using legitimate existing evidence.

CRA business audits may examine:

• Ledgers
• Journals
• Invoices
• Receipts
• Contracts
• Bank statements
• Electronic accounting records

CRA may also request explanations from accountants, bookkeepers or employees.

Prepare a clear package for each significant missing document.

For example:

Expense claimed: $12,500 legal fees

Supporting package:

• Bank payment
• Engagement letter
• Law firm’s account statement
• Email correspondence
• Duplicate invoice requested from firm
• General ledger detail

If you have already received a CRA request, internally link to Aterna’s What to Do If You Receive a CRA Audit Letter for guidance on organizing records and responding carefully.

Do Not Send CRA a Random Folder of Everything

More documents do not automatically create better evidence.

Organize records so each transaction can be followed easily.

For example:

Expense 001

Accounting account: Legal fees
Amount claimed: $12,500
Original receipt: Missing
Alternative support:

1. Engagement agreement
2. Bank payment
3. Duplicate statement
4. Email correspondence
5. Ledger entry

A clean reconciliation makes it easier to understand the claim.

CRA itself emphasizes the importance of audit trails linking supporting documents to accounting records.

What If Your Records Were Destroyed in a Fire, Flood or Disaster?

That is different from simply failing to maintain them.

CRA has specific support procedures where books and records are destroyed because of a disaster and directs affected businesses to contact the agency.

Businesses should still attempt to reconstruct records from available sources such as:

• Banks
• Credit-card companies
• Suppliers
• Customers
• Cloud accounting systems
• Email
• Accountants
• Payroll providers
• Government filings

This is another reason cloud backups and offsite record storage are valuable.

Ten Steps to Reconstruct a Missing Business Receipt

If you discover a missing receipt today, use this process.

Step 1: Identify the Exact Transaction

Record:

• Date
• Amount
• Supplier
• Accounting category
• Payment method

Step 2: Search Email

Search:

• Supplier name
• Amount
• Order number
• Product description

Many receipts exist digitally even when the paper copy is gone.

Step 3: Log Into the Supplier Account

Check:

• Amazon Business
• Software accounts
• Telecom portals
• Utility portals
• Office suppliers
• Equipment vendors

Download a duplicate invoice.

Step 4: Contact the Supplier

Ask for a duplicate invoice or account statement.

Step 5: Save Payment Evidence

Download:

• Bank statement
• Credit-card statement
• Cancelled cheque
• Electronic-transfer confirmation

Step 6: Locate Business Evidence

Look for:

• Contract
• Work order
• Calendar appointment
• Purchase order
• Delivery slip
• Employee expense claim
• Email discussion

Step 7: Document the Business Purpose

Do not write:

“Business expense.”

Write:

“Annual accounting software subscription used by finance department.”

Specific explanations are more useful.

Step 8: Review GST/HST Requirements

If an ITC was claimed, determine whether your reconstructed documents contain the required GST/HST information.

Step 9: Attach Everything to the Accounting Entry

Create one digital record.

Step 10: Fix the System

Ask why the receipt went missing and change the process so it does not happen repeatedly.

Build a Receipt System Before Tax Season

A good process can be simple.

Every purchase should move through:

Purchase → Receipt captured → Transaction recorded → Business purpose documented → Receipt attached → Account reconciled

Do this every month.

Not once a year.

Aterna’s Signs Your Business Has Outgrown Basic Bookkeeping explains why businesses with growing transaction volumes often need better accounting systems, stronger controls and more timely reconciliations.

Frequently Asked Questions

Can CRA deny a business expense if I lost the receipt?

Yes, an expense can be disallowed if you cannot adequately support the claim. CRA specifically warns that unsupported expenses may be denied.

However, CRA recognizes many forms of source documents, so losing the original receipt does not necessarily mean there is no other evidence available.

Is a bank statement enough for CRA?

It can help prove that a payment occurred, and CRA recognizes bank statements as business records. But the statement may not identify what was purchased or establish the business purpose.

Stronger support usually combines payment evidence with transaction details.

Is a credit-card statement enough?

The same principle applies.

A credit-card statement can support the payment, but additional documentation may be needed to establish what the expense was.

What if a vendor never gave me a receipt?

CRA says that when a supplier does not provide a receipt, you should record the supplier’s name and address, amount paid, payment date and transaction details in your expense journal.

Can I scan receipts and throw away the paper?

CRA accepts records stored in accessible and readable electronic formats and provides rules for converting paper documents into electronic images. Businesses should ensure their imaging and retention process meets CRA requirements before destroying originals.

How long should my company keep receipts?

Generally, CRA requires records to be maintained for at least six years from the end of the last tax year to which they relate.

Can I claim GST/HST without the original receipt?

ITC claims require prescribed supporting documentation. Other business documents may potentially provide the necessary information, but the documentation must satisfy GST/HST requirements.

Can CRA review electronic accounting records?

Yes.

CRA may request electronic records during an audit, and businesses are required to keep electronic information accessible and readable.

A Missing Receipt Is Easier to Fix Today Than During a CRA Audit Three Years From Now

Losing one receipt does not automatically destroy a legitimate business deduction.

But ignoring missing documentation is risky.

The best response is to reconstruct the transaction while the details are still available.

Find the bank or credit-card payment.

Request a duplicate invoice.

Search emails.

Retrieve the contract.

Find the delivery slip.

Document the business purpose.

Check GST/HST requirements separately.

Then attach everything to the accounting entry.

CRA does not look only for a piece of paper labelled “receipt.”

It looks for reliable records capable of supporting what the business reported.

The stronger your audit trail, the easier it is to explain the claim.

Aterna Advisors supports Canadian businesses with bookkeeping, accounting, tax compliance and CRA-related matters. If missing receipts are becoming a recurring year-end problem, the bigger issue may not be the individual receipt. It may be that the company’s financial-record system needs stronger monthly controls.
