Updated Checked by the Tax-Services.ca editorial team How we check
Nobody publishes an official or reliable price range for catch-up bookkeeping in Canada, so we won’t invent one. What we can tell you is that the price follows the amount of untidy history, not the number of months. Months of clean statements are cheap to catch up. A single year of missing receipts and mixed accounts isn’t.
What drives the price of catch-up bookkeeping?
Bookkeepers price the work in different ways (see the fee methods in our guide to how accountants charge). Whatever the method, the quote reflects these things.
| Driver | Cheaper | Costlier |
|---|---|---|
| Months behind | A few | Several years |
| Statements | All downloaded | Missing or from closed accounts |
| Receipts | Photographed and sorted | Lost or in a bag |
| Accounts | Business only | Personal and business mixed |
| Sales tax | Not registered | Registered with returns unfiled |
| Payroll | None | Staff with remittances due |
Everything in the right-hand column is time, and time is what you pay for. So the fastest way to lower a quote is to do the gathering yourself before anyone starts.
What should you gather first?
Bank and credit card statements for every month you’re behind, including any account you’ve since closed. Sales reports from every platform you sell on. Loan statements. Prior returns and any CRA letters. If GST/HST is involved, the reporting periods the CRA assigned you.
Ask the bank for missing statements now, because the request can take days to come back and that wait is the step that stalls most catch-up projects.
Where do you start if everything is a mess?
Picture Sam, a freelance photographer in Calgary who shoved every receipt into a banker’s box for two years. Sam doesn’t need to fix it all at once. A sensible order is to download the statements, sort the receipts by month, flag anything with a deadline, and only then hand it over. The tax-time panic eases once you can see the pile has edges.
Give the bookkeeper a short note about anything odd: a business loan from a relative, a laptop bought personally and used for work, a refund you never banked. Surprises found midway are the ones that blow up a quote.
Why does lateness cost more than the bookkeeping?
Because the CRA charges penalties by formula, and the formula keeps running. A late personal return starts with a charge of 5 cents on every dollar you owe, then adds a cent per dollar for each full month, for up to a year. Owe $2,000 and file six months late? That’s $100 to start plus $120, so $220.
Late GST/HST works on smaller numbers. The start is one cent per dollar owing. Each full month adds a quarter of that first charge, and the count stops at 12. On $2,000 owing and six months late, the first charge is $20 and each month adds $5, so the total is $50. Interest can come on top, and we didn’t confirm the current rate. Nothing is charged if you owe zero or the CRA owes you a refund.
So the order of work matters. If a return is overdue, do the numbers for that year first.
Can you get penalties reduced?
Sometimes. The CRA runs a Voluntary Disclosures Program that can reduce penalties case by case for people who come forward on their own to fix a mistake. Conditions have changed in recent years, so read the CRA’s eligibility page before you count on it. Ask your bookkeeper if your case fits.
Can you estimate what you owe before hiring anyone?
Roughly, yes. Add up a year’s deposits and expenses, then put the net profit into the self-employed tax calculator. It leaves out EI and doesn’t lower CPP for deductions, so the answer is a floor. For sales tax, the GST/HST calculator shows the tax on a sale, $13 on $100 in Ontario. Once you’re current, the tax installments calculator plans your payments so you don’t fall behind again.
See what your next dollar of profit costs in the marginal tax rate calculator. In Ontario for 2026 it’s 19.05% at $45,000 of taxable income and 29.65% at $70,000.
Mistakes when catching up
Paying for tidy reports on data that’s still wrong. Booking guesses as facts. Mixing years in one file. And, the costly one, filing an estimate to stop the penalty clock and never fixing it.
Keep everything you gather. The CRA’s circular on books and records says they must be kept for a minimum of six years from the end of the last tax year they relate to.
How we checked the figures
Penalty formulas and record rules are from Canada Revenue Agency pages on GST/HST filing penalties, late-filing penalties for individuals, the Voluntary Disclosures Program and record keeping, read in September 2026. The 2025 return page states the individual penalty; we found no 2026 return dates published. Fee levels are left out on purpose. This site isn’t affiliated with the CRA.
Frequently asked questions
What does catch-up bookkeeping cost in Canada?
We couldn't confirm a reliable range. Get written quotes after you've gathered your statements, since disorder drives the price.
What do I need to gather?
Bank and card statements for every missing month, sales reports, loan statements, prior returns and any CRA letters.
What's the penalty for a late GST/HST return?
It starts at one cent per dollar owing, then adds a quarter of that for each full month, up to 12 months. Nothing is charged if you owe zero or are owed a refund.
Can late penalties be reduced?
Sometimes, through the CRA's Voluntary Disclosures Program. Check its eligibility page first.
Should I file before the books are done?
If a return is overdue, do that year first. An estimate can stop penalties from growing, but fix it once the books are complete.
