How Do I Fix Bookkeeping That's Months Behind?

Start with anything that has a CRA deadline: payroll remittances and GST/HST returns. Then gather every bank and credit card statement, fix your accounting software setup, and work forward month by month, reconciling each account to its statement before moving on. Finish with year-end adjustments, then put a monthly close in place so it doesn't happen again.

Falling behind is common, especially in a growing business where the owner's time goes to customers and crews first. It's fixable. What matters is the order you do it in, because some of what's overdue carries penalties and some of it doesn't.

What does being behind actually cost?

Being behind on the books usually isn't penalized on its own. The costs come from what it holds up: filings, remittances and decisions.

Interest is charged on top of these, and it compounds daily.

The costs that don't show up on a CRA notice are often bigger:

• You can't see your cash. Without current books, you don't know what's coming in, what's owed or what you can safely spend. That's how profitable businesses end up short on cash.
• You miss deductions. Expenses that aren't recorded aren't claimed.
• Lenders and bonding companies wait. Most require current financial statements, and a delay can hold up financing.
• Tax planning becomes impossible. You can't plan around numbers you don't have, so decisions like salary versus dividends get made at the last minute.

How to catch up, step by step

1. Find out exactly how far behind you are

Before touching any transactions, list three things:

• The last month that was fully reconciled for each bank account and credit card.
• Every filing and remittance that's overdue: payroll, GST/HST, T4s and T5018s, corporate tax returns and instalments.
• What's due in the next 90 days.

That list tells you what to do first and whether the catch-up has to be finished by a specific date.

2. Deal with deadlines before history

Keep current payroll remittances and GST/HST filings on time while you catch up. Falling further behind on these while fixing the past only adds penalties.

If returns have already been missed, talk to an accountant before the CRA contacts you. Under the Voluntary Disclosures Program, which was updated on October 1, 2025, disclosures made before the CRA reaches out can qualify for full penalty relief and 75% interest relief. Once the CRA has contacted you, interest relief drops to 25%.

3. Gather every record

Download statements for every business bank account, credit card, line of credit and loan for the whole period. Pull payroll reports, sales invoices, supplier bills and receipts. Digital copies are fine. The CRA generally requires you to keep business records for six years.

Bank statements are the backbone of the catch-up. Missing receipts can often be worked around; missing statements can't.

4. Fix your software setup before entering anything

Make sure your opening balances match your last completed year-end financial statements, that bank feeds are connected, and that your chart of accounts makes sense for how the business runs today. If the file is badly damaged, or you're on software that no longer fits, it can be faster to start a clean file or migrate than to repair the old one.

5. Work forward one month at a time and reconcile

Record and categorize each month's transactions, then reconcile every bank and credit card account to its statement before moving to the next month. Reconciliation is the step people skip when they're behind, and it's the one that makes the numbers trustworthy. Catching an error in month two is far easier than finding it in month nine.

6. Bring receivables and payables up to date

Match payments to invoices so you know who still owes you and who you owe. This step often turns up cash: invoices that were never sent, or never followed up.

7. True up payroll and sales tax

Compare the GST/HST collected and paid in your books to what was actually filed, and your payroll liabilities to what was remitted. Differences need to be corrected with the CRA, not just in your books.

8. Close and lock each period

Review the profit and loss and balance sheet for each month, check balances like the shareholder loan account, then lock the period in your software so nothing changes after the fact. Once you're current, your accountant can finish the year end.

Should you catch up yourself or get help?

Doing it yourself can work if you're only a month or two behind, have a single bank account, and know your accounting software well.

Once you're several months behind, have payroll and GST/HST in the mix, or have missed a filing, it usually makes sense to bring in help. The work isn't only data entry. It's reconciling, correcting errors and fixing what was filed with the CRA, and the hours an owner spends on it come straight out of running the business.

How long does catching up take?

It depends on four things more than on the number of months:

• Transaction volume. A business with a few hundred transactions a month catches up far faster than one with thousands.
• How complete your records are. Downloaded statements and organized receipts save the most time.
• Payroll and sales tax. Each adds a true-up step.
• The state of the software file. A damaged file can take longer to repair than to rebuild.

For most businesses a few months behind, a focused catch-up is measured in weeks, not days.

How do you stay caught up?

The fix is a monthly close: every account reconciled, every month, within a few weeks of month end. A good monthly process includes:

• Bank feeds connected and transactions reviewed weekly.
• Receipts captured when they happen, not at year end.
• Payroll and GST/HST reconciled every time they're filed.
• A short monthly report you actually read.

Frequently asked questions

Will the CRA penalize me just for being behind on bookkeeping? Usually not on its own. The penalties come from what bookkeeping delays: late payroll remittances, late GST/HST returns and late corporate tax returns.

Can I file my corporate tax return if my bookkeeping isn't done? Not accurately. Your T2 is based on your year-end financial statements, which come from your books. If your filing deadline is close, talk to your accountant about priorities.

What if I'm missing receipts? Bank and credit card statements show most of what you need. Many suppliers can reissue invoices, and your accountant can advise on how to support expenses without a receipt.

I've missed some filings. What should I do? Speak to an accountant before the CRA contacts you. The Voluntary Disclosures Program offers more relief for disclosures made before the CRA reaches out.

How do I keep my books from falling behind again? Close the books every month: reconcile each account, review a short report, and deal with payroll and sales tax as you go. Many owners hand this to a bookkeeping team so it happens whether or not they have time.
