IntroductionĀ
Receiving aĀ CRA reassessment noticeĀ can raise immediate questions about what changed, why it changed, and whether your bookkeeping records support the amounts reported. A reassessment may point to missing documentation, incorrectly classified expenses, GST/HST discrepancies, unsupported deductions, or unreconciled transactions.Ā
AtĀ NCSGX, we understand the importance of keeping Canadian business records organized,Ā accurate, and supported by proper documentation.Ā When a CRA review exposes gaps in the books, professionalĀ bookkeepingĀ support can help bring records up to date and create a clearer trail for future reporting.Ā Ā
Key TakeawaysĀ
- AĀ CRA reassessment noticeĀ does not automatically mean your business made an intentional error. Review what CRA changed and why.Ā
- Start by comparing theĀ notice of reassessmentĀ with the filed return, bookkeeping records, and supporting documents.Ā
- Catch-up bookkeepingĀ can help identify unreconciled accounts, missing records, GST/HST discrepancies, and otherĀ correcting bookkeeping errorsĀ that may need attention.Ā
- If you disagree with the reassessment, understand the difference between providing information, requesting an adjustment, and filing a formalĀ CRA notice of objection.Ā
- When consideringĀ how to respond to a CRA reassessment, check the applicable deadline and keep a clear record of all informationĀ submittedĀ to CRA.Ā
Cleaning Up Your Books After a CRA Review or Reassessment NoticeĀ
Receiving aĀ CRA reassessment noticeĀ can be stressful, especially when the amount owing is higher than expected. But the notice is also a useful signal: something in the filed information, supporting records, or CRA’s review needs a closer look.Ā
A reassessment may exposeĀ missing documentation, incorrectly classified expenses, GST/HST errors, unreconciled transactions, unsupported deductions, inaccurate balances, or inconsistent records. The right response is not simply to make the accounting file look better. You need to understand what changed, verify the underlying transactions, and build a clear record supporting your position.Ā
For many Canadian businesses, that means going beyond the tax return and doing a properĀ Bookkeeping cleanup.
What a review or reassessment notice actually meansĀ
AĀ notice of assessmentĀ is the CRA’s assessment of a return. AĀ Notice ofĀ ReassessmentĀ reflects a later change to an assessment. Receiving one doesĀ not automatically mean fraud or intentionallyĀ doingĀ wrong activities. Adjustments can arise because information was missing, amounts did not match CRA’s records, a deduction was not adequately supported, or CRA reached a different conclusion about an amount.Ā
For corporations, the normalĀ T2 reassessment periodĀ is usually three years from the date CRA sent the original notice of assessment if the corporation was a Canadian-controlled privateĀ corporation (CCPC), and four years if it was not a CCPC. Exceptions can apply, including misrepresentation attributable to neglect, carelessness,Ā wilfulĀ default, fraud, or certain waivers and special adjustments.Ā Ā
First things to do when the notice arrivesĀ
Use this checklist before changing your books or contacting CRA:Ā
- Read the entire notice carefully.Ā
- Identify the tax year or reporting periodĀ involved.Ā
- Note exactly what changed: income, expenses, deductions, credits, GST/HST, interest, or penalties.Ā
- Compare the notice with theĀ originally filed return and accounting records.Ā
- Review CRA’s explanation of the adjustment.Ā
- Check every response or objection deadline.
- Gather supporting records before deciding what went wrong.
- Get professional help if the issue is significant, technical, or disputed.Ā
Deadlines matter. For a Canadian corporation, a formal income tax objectionĀ generally mustĀ be filed withinĀ 90 daysĀ from the date of the notice of assessment or reassessment.Ā
Why your books need a cleanup
Ā
A CRA review can reveal problems that existed well before the notice arrived. Cleaning up those issues helps establish whether the reassessment is supported by the actual transactions.
Ā
Issue | What it can cause | What to review |
| Unreconciled bank accounts | Incorrect income or expenses | Bank statements and ledger |
| Missing receipts | Unsupported deductions | Receipts and proof of payment |
| Duplicate transactions | Inflated expenses | Transaction listings |
| GST/HST discrepancies | Incorrect net tax or ITCs | GST/HST reports and invoices |
| Payroll discrepancies | Incorrect liabilities | Payroll reports and remittances |
Catch-up bookkeeping is useful when records have fallen behind or contain incomplete transactions. However, proper catch-up bookkeeping is more than entering old transactions. CRA describes
Business Records as including accounting and financial documents such as ledgers, financial statements, invoices, receipts, contracts, and bank statements that support business transactions.
Step-by-step book cleanupĀ
Use this workflow whenĀ correcting bookkeeping errorsĀ after a review or reassessment.Ā
Step 1: Identify what CRA changedĀ
Create a simple reconciliation between the original filing and the CRA adjustment. Quantify each difference.Ā
Step 2: Reconcile the affected accountsĀ
Review bank accounts, credit cards, GST/HST accounts, payroll liabilities, loans, A/R and A/P. An unreconciled balance can hide the transaction that caused the problem.Ā
Step 3: Trace transactions to source documentsĀ
For material items, match the ledger entry to the invoice, receipt, contract, bank transaction, or other evidence.Ā
Step 4: Correct bookkeeping errorsĀ
Fix duplicate entries, incorrect classifications, missing transactions, or unsupported amounts. Keep a record explaining each correction instead of simply overwriting history.Ā
Step 5: Review GST/HST implicationsĀ
Check whether sales and purchases were treated correctly and whether claimed input tax credits are supported. CRA requires GST/HST records to contain enough information to support the amounts reported and ITCs claimed.Ā
Step 6: Reconcile tax and liability accountsĀ
Compare the accounting balances with CRA statements and filed returns. Investigate unexplained differences.Ā
Step 7: Document every correctionĀ
Keep notes showing what changed, why it changed, the source document, and the date of the adjustment.Ā
Step 8: Prepare a clean review trailĀ
Someone unfamiliar with the file should be able to follow the transaction from source document to bookkeeping entry, reconciliation, tax return, and CRA response.Ā
Gathering and organizing your supporting documentationĀ
The records required will depend on what CRA is reviewing. A practical documentation package may include:Ā
- Sales and purchase invoicesĀ
- Receipts and proof of paymentĀ
- Bank and credit-card statementsĀ
- Payroll recordsĀ
- GST/HST records and working papersĀ
- Accounting ledgers and journal entriesĀ
- Financial statementsĀ
- Evidence explaining business purposeĀ
CRA generally requires businesses to keep records and supporting documents forĀ six years from the end of the last tax year they relate to, although certain records, such as some long-term property or corporate historical records, can have longer or indefinite retention requirements.
Responding to the CRAĀ
There are three situations that should be kept separate.
A. Providing requested information
Ā Ā Ā If CRA is conducting a review and asks for documents, provide the requested information by the stated deadline.Ā Ā Ā Ā CRA can make its decision using the information available if requested information is not provided.
B. Requesting a reassessment or adjustment
Ā Ā If you discover that a previously filed amount is wrong, the appropriate correction process depends on the returnĀ Ā Ā Ā involved. For a corporation, CRA allows a business to request a reassessment of its T2 return electronically or inĀ Ā Ā Ā writing with relevant supporting information.
C. Filing a formal CRA notice of objection
Ā Ā If you disagree with an assessment or reassessment, aCRA notice of objection is the formal dispute mechanism.Ā Ā Ā Ā For corporations, the general deadline is 90 days from the date of the notice. The objection should explain theĀ Ā Ā Ā Ā Ā disputed issue, facts, reasons, and supporting documentation. Corporations canĀ generally fileĀ aĀ FormalĀ Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā objection online through My Business Account or, where an authorized representative is involved, throughĀ Ā Ā Ā Ā Ā Ā Ā Ā Represent a client.Ā
Keeping it from happening againĀ
A CRA-ready bookkeeping routine is usually less expensive and less disruptive than reconstructing several years of records.Ā Ā
Focus on consistency:Ā
- Reconcile bank andĀ credit cardĀ accounts monthly.Ā
- Review GST/HST payable and input tax credit accounts regularly.Ā
- Store invoices and receipts in organized digital folders.
- Keep personal and business spendingĀ separately.Ā
- Review A/R and A/P balances each month.Ā
ConclusionĀ
A CRA review or reassessment is a good reason to take a closer look at your bookkeeping, supporting documents, and reporting processes.
