Catching up on overdue bookkeeping: What to do
July 23, 2026
At a Glance. Overdue bookkeeping can almost always be caught up on, but every month you wait costs more: a late filing with an outstanding balance results in a penalty of 5% of the unpaid balance plus 1% per full month, for both the CRA and Revenu Québec, in addition to daily compounded interest. For budgeting purposes, the Bankeo Fee Barometer is a reliable benchmark: a business’s accounting costs a median of about $3,000 per year (most fall between $500 and $6,000), and the cost of catch-up accounting is roughly this annual benchmark multiplied by the number of years to be reconstructed. The winning strategy: stop letting the backlog grow, gather all the documents, prioritize GST/QST and source deductions, then hand the entire batch over to an accountant who accepts urgent cases.
A stack of bills in a box, statements piling up, a notice from Revenu Québec buried under the rest: falling behind on bookkeeping is one of the most common problems among Quebec entrepreneurs, and one of the easiest to let drag on. The good news: even if your records are six months, a year, or even three years behind, you can get them back on track with a proven method, a budget you can work with, and the right professional. This guide shows what really needs to be done right away, how much it costs to do catch-up accounting according to the Bankeo Fee Barometer, and how to quickly be matched with an accountant who accepts this type of assignment.

In Quebec, a business reports to two agencies: the Canada Revenue Agency (CRA) at the federal level and Revenu Québec at the provincial level. When bookkeeping falls behind, it’s not just numbers that are missing, it’s overdue obligations that keep piling up, with penalties that add up on their own.
The primary cost of a delay isn’t the accountant’s fee, it’s the penalties and interest that accrue while the file is pending. Here are the main rates in effect for 2026.
| Noncompliance | Standard Penalty | Administration |
|---|---|---|
| Late tax return with an outstanding balance (T1, TP1, T2, CO-17) | 5% of the outstanding balance + 1% per full month, up to 12 months | CRA and Revenu Québec: Each Handles Its Own Matters |
| Repeated Late Filings | Up to 10% of the balance + 2% per month, for up to 20 months | CRA (similar rules in Quebec) |
| Late Filings: QST, GST Administered in Quebec, Quebec source deductions | 7% to 15% of the amount due, depending on the number of days overdue | Revenu Québec |
| Late Federal Withholdings | 3% to 10% of the amount owed | CRA |
| Any outstanding balance | Interest is compounded daily at the prescribed rate, which is revised quarterly | CRA and Revenu Québec |
In addition to these penalties, there is a more serious risk: if you fail to file any returns at all, the CRA and Revenu Québec can issue an arbitrary assessment, that is, estimate your income on your behalf and tax you based on that figure, which is often higher than your actual income. To challenge this, you’ll need… reconstructed records. In other words, catching up becomes mandatory anyway, but under the worst possible conditions.
If you’ve never filed returns, the CRA’s Voluntary Disclosure Program and its equivalent at Revenu Québec can reduce penalties, but there’s one key condition: you must take the first steps before the tax authorities contact you. This is yet another reason to act now rather than wait for a letter. An accountant experienced in catch-up accounting will verify your eligibility and prepare your case.
This is the question that concerns most business owners, and it should be answered based on data rather than guesswork. The Bankeo Fee Barometer Actual accounting fees in Quebec: the median is around $3,000 per year, with most businesses paying between $500 and $6,000 depending on the industry and volume. Based on actual fees from 1,248 contracts finalized through Bankeo (2024-2026), out of more than 15,000 requests received since 2023, this is the most reliable benchmark in the Quebec market.
Catching up follows a simple logic: reconstructing a year’s worth of records costs roughly the same as a year of ongoing bookkeeping, adjusted for three factors: the volume of transactions, the condition of the documents, and the returns to be filed (GST/QST, source deductions, taxes). Here’s how to assess your situation.
| Extent of the Backlog | Common Tasks | Cost Benchmark (Bankeo Fee Barometer) |
|---|---|---|
| A few months, complete documents | Data entry, reconciliations, updating quarterly tax information | At the lower end of the range: a few hundred dollars |
| A Full Year | Data entry and reconciliations for 12 months, GST/QST returns, tax return to be prepared | Around the annual median of about $3,000 |
| Two to three years | The total, multiplied by the number of years to be reconstructed, from the oldest to the most recent | The annual benchmark per year of delay ranges from $500 to $6,000, depending on the volume |
| Complex Case: Missing Documents, Unfiled Tax Returns, Ongoing Audit | Reconstructing Records from Bank Statements, Representation Before the Authorities | At the high end of the range, plus representation fees: ask for a detailed quote |
Two tips for staying within your budget. First, ask for a fixed-price package for the catch-up work, an amount known in advance, rather than an open hourly rate: our comparison Hourly rate or flat fee explains why. Next, split the estimate into two parts, the (one-time) catch-up work and the (recurring) ongoing bookkeeping, to compare each to the appropriate benchmark in the Barometer.
A successful catch-up always follows the same steps. Following them ensures you don’t end up paying twice for the same work.
The real bottleneck in catching up isn’t the method, it’s finding a professional who has availability right now. In the middle of tax season, many firms turn down new catch-up assignments; outside of tax season, you still need to know who will take them on. That’s exactly what Bankeo does: you describe your situation (number of years behind, legal structure, taxes and source deductions involved, status of your documents), and we search our network of over 1,500 accountants to find those who take on catch-up cases and have short-term availability. Initial matching takes place within 48 hours; the service is free and non-binding, and we’re always there to support you: if the first match isn’t a good fit, we’ll introduce you to others at no cost.
In terms of personnel, an experienced bookkeeper is sufficient for data entry and reconciliations; if T2 and CO-17 forms are overdue or if an audit is underway, consult a CPA who is a member of the Ordre des CPA du Québec and authorized to file these returns and represent the business before the authorities. Our comparison CPA or bookkeeper explains who does what, and at what cost. Trust is also backed by reviews: entrepreneurs matched through Bankeo give us a rating of 4.7/5 based on over 180 Google reviews.

Find my accountantThis data comes from the Bankeo Fee Barometer, based on actual fees from 1,248 contracts concluded through Bankeo (2024-2026), out of more than 15,000 requests received: the median accounting fee is around $3,000 per year, with most businesses paying between $500 and $6,000. The cost of catching up is roughly this annual benchmark per year of books to be reconstructed, adjusted according to the volume of transactions, the condition of the documents, and the returns to be filed. Request a fixed-price package rather than an open hourly rate.
A late tax return with an outstanding balance results in a penalty of 5% of the unpaid balance plus 1% for each full month of delay, up to 12 months, for both the CRA and Revenu Québec. In the event of a repeat offence, the penalty can rise to 10% plus 2% per month. Late payments (QST, source deductions) are subject to a penalty ranging from 7% to 15% of the amount due, depending on the number of days late, and interest, compounded daily, is added to any outstanding balance.
The CRA and Revenu Québec can issue an arbitrary assessment: they estimate your income themselves and tax you based on that figure, which is often higher than your actual income, leaving it up to you to challenge it with reconstructed records. If tax returns have never been filed, the federal and Quebec voluntary disclosure programs can reduce penalties when you take the first steps before being contacted. An accountant experienced in catch-up accounting will work with you to prepare your case.
A few days for a delay of a few months with complete supporting documents; a few weeks for one or two years to reconstruct; longer if documents are missing or if GST/QST returns have never been filed. An accountant taking on these files as a rush job starts with the most critical obligations (source deductions, GST/QST), then reconstructs the years from the oldest to the most recent. Providing complete bank statements from the outset significantly shortens the turnaround time.
Not necessarily for data entry and reconciliations: an experienced bookkeeper can handle this work very well. A CPA who is a member of the Ordre des CPA du Québec becomes essential when T2 and CO-17 returns are overdue, when an audit is underway, or when the business needs to be represented before tax authorities. Many catch-up projects combine both roles: the bookkeeper reconstructs the records, and the CPA reviews and files them.
Establish a routine before you’ve even finished catching up: cloud-based accounting software connected to your bank accounts, real-time document filing, monthly reconciliation, and a calendar of GST/QST and source deductions deadlines. If you’re short on time, outsource your ongoing bookkeeping: this is exactly the scenario where a monthly flat-rate plan costs less than the next catch-up accounting session. Your Bankeo-assigned accountant can help you set up this routine, we’re always here to support you.
