It's important to clarify that the CRA does not have direct access to your bank account to monitor transactions as they happen. They cannot simply log in and view your account activity. The CRA relies on the bank statements, receipts, and proofs of payment that you provide during an audit.
We already mentioned that bank statements are important paperwork during an audit process. The CRA typically ensures that your income deposits in your bank match your reported income. If you have a significant discrepancy, then it could raise a red flag which often calls for further investigation.
Bank statements can serve as proof of payment if they clearly display the transaction details. They provide evidence that funds were withdrawn from your account for a specific expense. However, bank statements often lack the detailed description of the purchase that a traditional receipt would include.
If you choose to claim an expense without a receipt, make sure you have other proof of the transaction, either on a bank statement or as detailed notes. You need to be able to demonstrate that the expense is solely for business use and that the amounts have been recorded and calculated accurately.

Bank account records or credit card statements are a good place to start. If you don't have these, you could try to reconstruct your records with additional information.
The most common proof of income documents are pay stubs, tax forms, and bank statements. For self-employed applicants, you should request 1099s and bank statements. For regular wage employees, you should request recent pay stubs.
Basically, the de minimis safe harbor allows businesses to deduct in one year the cost of certain long-term property items. IRS regulations set a maximum dollar amount—$2,500, in most cases—that may be expensed as "de minimis," which is Latin for "minor" or "inconsequential." (IRS Reg. §1.263(a)-1(f) (2025).)
There are many alternatives to pay stubs, including tax returns, bank statements, employer income letters, 1099s, Social Security statements, court-ordered payments, unemployment benefit letters, annuity statements, interest and dividend income statements, and bonus/incentive payout records.

Which Taxpayers the IRS Audits Most Often. Oddly, people who make less than $25,000 have a relatively high audit rate. This higher rate is because many of these taxpayers claim the earned income tax credit, and the IRS conducts many audits to ensure that the credit isn't being claimed fraudulently.

Unexplained bank deposits are the top trigger for HMRC tax investigations. Can HMRC see my personal bank accounts? Yes, HMRC can access data from banks, payment platforms, and other sources.

Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit. The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.

How far back can the IRS go to audit my return? Generally, the IRS can include returns filed within the last three years in an audit. If we identify a substantial error, we may add additional years. We usually don't go back more than the last six years.
