Updated Checked by the Tax-Services.ca editorial team How we check
The bookkeeping penalties in Canada start at a fine of $1,000 and can reach $25,000, plus up to 12 months in jail, for failing to keep the records the Income Tax Act requires. That’s the court route, and it’s rare. Most businesses meet the smaller, automatic penalties first, and those come from late returns and false claims rather than from messy books alone.
What does the law say you have to keep?
Under section 230 of the Income Tax Act, if you run a business you must hold books and records in Canada, at work or at home, in a form that shows the tax you owe. That’s the whole test. There’s no required software and no required chart of accounts. If a stranger can follow your sales, expenses and payroll back to a receipt or invoice, you’re in good shape.
Hold on to them for six years minimum, counted from the end of the last tax year they cover. If you’re in a dispute, the clock runs until the objection or appeal is settled. And if the CRA decides your books are inadequate, it can order you to keep specific records going forward.
Which bookkeeping penalties can you actually face?
We found no page that sets a dollar penalty for untidy books by themselves. The amounts below are the ones the CRA and the Act actually name.
| Problem | Penalty | Source |
|---|---|---|
| Not keeping required records (offence) | Fine of $1,000 to $25,000, up to 12 months in prison, or both | Income Tax Act, s. 238(1) |
| Corporation files its T2 late | 5% of unpaid tax, then 1% per complete month late, capped at 12 months | CRA, avoiding penalties |
| Repeat late T2 after a CRA demand | 10% plus 2% a month, up to 20 months | CRA, avoiding penalties |
| GST/HST return filed late with a balance owing | 1% of the amount, plus 25% of that 1% for each full month, up to 12 months | CRA, GST/HST penalties |
| Knowingly or grossly negligently false return | The greater of $100 or 50% of the tax understated | Income Tax Act, s. 163(2) |
What does a late return cost in real dollars?
Say an Ontario corporation earns $300,000 of active business income. The corporate tax calculator shows $35,088 of tax for 2026. File the T2 three full months late and the penalty is 5% ($1,754.40) plus 3% ($1,052.64). That’s $2,807.04, before any interest.
GST/HST is smaller but it adds up. Put $30,000 of sales through the GST/HST calculator in Ontario and you collect $3,900. If you file four full months late with all of it still owing, the penalty is $39 plus four times $9.75, so $78.
Where bad records really hurt
Here’s the pattern that catches people. You claim an expense, the CRA asks for the receipt, and you can’t find it. Then the question isn’t about penalties for bookkeeping at all. It’s about how you support the number on the return.
That’s where the false statement penalty comes in. The CRA has to show you acted knowingly or with gross negligence, and a simple mistake or a misunderstanding of the law doesn’t meet that bar. Sloppy records make it easier for a reviewer to argue the second one, though, so it pays to keep the paper trail.
Three habits prevent most of it.
- Record each sale and expense within days, with the receipt attached.
- Bank and card statements get the same six years.
- File on time even when you can’t pay. The late-filing penalty is charged on tax unpaid at the deadline, so filing on time removes it.
Payroll deserves its own care. If you have staff, the payroll remittance calculator gives you a check on what you should be sending in, and mixed-up payroll records are a common way to end up in a review. Self-employed people can test their own year with the self-employed tax calculator. For more tools, see the business tax hub.
What we couldn’t confirm
We didn’t find a published scale for how often the CRA prosecutes record-keeping offences, and we won’t guess. We also didn’t confirm how provincial bodies treat records. Provincial taxes follow provincial rules, so ask the authority you file with.
Where the numbers come from
The fines and imprisonment terms come from section 238 of the Income Tax Act on the Justice Laws website. The retention period is from CRA Information Circular IC78-10. Penalty percentages are from CRA pages on corporation penalties and GST/HST filing, read in September 2026. Examples use this site’s own calculators. We’re an independent site with no link to the CRA or any government.
Frequently asked questions
How long do I have to keep business records in Canada?
At least six years from the end of the last tax year they relate to. Keep them longer if you have an open objection or appeal.
Can the CRA fine me for untidy books?
The Income Tax Act makes failing to keep required records an offence, with a fine of $1,000 to $25,000, jail up to 12 months, or both. Charges are for serious cases.
What is the penalty for a false or misleading tax return?
The greater of $100 or 50% of the tax understated, when the CRA shows you acted knowingly or with gross negligence.
What is the late filing penalty for a corporation?
5% of the unpaid tax plus 1% for each full month late, up to 12 months. It is higher if you were penalized in the past three years.
Do I need accounting software?
No. The law asks for records that let the CRA work out your tax, on paper or electronically.
