What Your Bank Statement Doesn't Prove: Receipt Recordkeeping for Sole Proprietors

A bank statement is a good record of one thing: money moved. It shows the date, the amount, the direction, and usually a merchant name. For a sole proprietor assembling a year of expenses, that is a genuinely useful starting point — it is the input Heightly works from.

It is also, on its own, not quite what either tax authority asks you to keep.

The reasoning is the same in both countries; the rules differ mainly on how long you have to hold the records. Each section below states the shared point first, then splits by country.

The element a statement is missing

A statement tells you that a payment happened. It does not tell you what the payment was for — and business purpose is the thing being substantiated. Both authorities get there, by slightly different routes.

United States

The IRS is unusually specific. Its guidance on what kind of records to keep says supporting documents for a business expense should identify:

1. the payee
2. the amount paid
3. proof of payment
4. the date incurred
5. a description of the item purchased or service received that shows the amount was for a business expense

A bank statement gives you the first four cleanly. It almost never gives you the fifth. SQ *THE MARKET 604-555-0134 establishes that $88.40 left your account on 12 March and went to a merchant. It says nothing about whether that was client catering or your own groceries.

The IRS makes the point directly in the same guidance: "A combination of supporting documents may be needed to substantiate all elements of the expense." Account statements and credit card statements appear on its list of supporting documents — as one entry among several, not as a complete answer.

Canada

The CRA arrives at the same place from a different direction. Information Circular IC05-1R1, Electronic Record Keeping lists what counts as a source document: sales invoices, purchase invoices, cash register receipts, written contracts, credit card receipts, delivery slips, deposit slips, work orders, dockets, cheques, bank statements, and tax returns.

Bank statements are on that list — as one item on it. The circular is explicit that taxpayers keeping electronic records must also retain their source documents. A statement is part of the record, not the whole of it.

Both countries

Some categories are stricter again. Travel, meals, gifts and vehicle expenses carry their own substantiation requirements on both sides of the border, and a line on a statement does not come close to meeting them.

How long you have to keep them

This is where the two regimes genuinely differ, and it is the part worth knowing for your own country rather than in general.

United States

Until the period of limitations for that return expires. Per the IRS guidance on how long to keep records, that is generally three years from the filing date — extending to six years if you omitted more than 25% of the gross income shown on the return, with no limit where a return was fraudulent or never filed.

Two carve-outs matter for a sole proprietor. Employment tax records are held at least four years. And records for business assets run until the limitations period expires for the year you dispose of the asset — so a piece of equipment you use for a decade means a decade of paperwork.

Canada

Simpler to state: six years from the end of the last tax year the records relate to, under subsection 230(4) of the Income Tax Act. Destroying them earlier requires written permission from the CRA first, and disposing of records without it can be prosecuted.

The practical reading

Assume six years, and longer for anything touching an asset you still own. That satisfies both.

Digital copies are fine — with conditions

Neither authority requires a shoebox of fading thermal paper. Both accept electronic records. Canada is the more prescriptive of the two about what happens when you throw the paper away.

Canada

The CRA's general position is that records must be kept, and that records kept electronically must be retained in an electronically readable format for the full retention period — with an accessible and useable copy available if the CRA asks for one. Keeping a scan alongside the paper is uncontroversial.

Going further and disposing of the paper is where conditions attach. IC05-1R1 says paper source documents imaged in accordance with the applicable national standard may be disposed of, with the images kept as the permanent record — and it sets out what an acceptable imaging program involves: a documented process, a logbook of what was imaged and when, images of commercial quality that are legible on screen or on paper, quality control, and imaging software that maintains an index permitting the immediate location of any record.

Worth reading in full before you rely on it, and worth noting those conditions come via a national standard the circular cites from 1993. But the practical shape is clear enough: a folder of 4,000 photos named IMG_2291.jpg is not going to satisfy anyone. If you intend to throw the paper away, the archive needs to be organized enough that any single document can be produced on request.

United States

Briefer, and pointing the same way: whatever electronic system you choose should meet the same basic recordkeeping principles as paper, and all requirements that apply to hard copy books and records also apply to electronic records.

The caveat if you use a service

IC05-1R1 is clear that where imaging is done by a third party, the taxpayer remains responsible for ensuring it was done acceptably — and more generally, contracting the record-keeping function out to a bookkeeper, accountant or software provider does not transfer the obligation. The same principle holds in the US. Whoever holds the files, the records are yours to produce.

Making it a habit rather than a March problem

The failure mode is familiar to anyone who has done a year-end for a sole proprietor. The statements are complete, because the bank produces them whether or not anyone is paying attention. The receipts are not, because they depend on a person remembering — and a year later the ones that matter most are the ambiguous ones nobody can now explain.

The fix is not complicated: capture the receipt when the transaction happens, into something that will still hold it in six years.

Shoeboxed(Paid link) is one option for that specific job. You send it receipts — photographed, emailed, or physically mailed in — and it digitizes and stores them. Its role is capture and storage, which is the gap a bank statement leaves.

Being able to search that archive is not a compliance requirement. It is a convenience, and the moment you appreciate it is the one where somebody has asked about a single $340 charge from three years ago and you need the receipt for it this week — an audit query, a client dispute, a warranty claim. Rummaging through a shoebox or a phone camera roll on that timeline is where good intentions usually come apart.

Where this leaves Heightly

Heightly is AI-assisted bookkeeping for unincorporated sole proprietors. It reads your bank and credit card statements, sorts the transactions into Schedule C or T2125 categories, flags what needs a human decision, and produces a Tax Prep Report you or your accountant can work from.

The point of it is that most sole proprietors do not need a full accounting system to file a return. Platforms like QuickBooks Online and Xero are built for businesses that invoice customers, chase receivables, schedule payables and run payroll — and you pay for that machinery every month whether you use it or not. If what you actually need once a year is a categorized set of income and expenses in the right boxes, that is a much smaller job, and Heightly does the bookkeeping part of it at tax-time cost rather than as an ongoing subscription.

When the business grows past that — real invoicing, accounts receivable and payable, payroll, monthly financial statements — the accounting platform becomes the right tool, and we say so on our resources page. Until then it is usually a subscription to features you are not using.

What Heightly does not do is collect receipts, and the report says so. Your Tax Prep Report notes where documentation is your responsibility, and points at the same CRA and IRS requirements described above — because the report is built from statement data, and statement data has the limitation this article is about.

The two halves fit together fairly neatly. The Excel file Heightly produces lists every transaction with its date, amount, merchant and category, which makes finding a transaction easy — sort by category, filter by merchant, and the year is in front of you. What it cannot do is hold the document that explains the transaction. That is the piece your receipt archive keeps, and the piece an auditor eventually asks for.
