Canadian businesses face thousands of GST/HST audits every year. The Canada Revenue Agency (CRA) conducts about 70,000 GST/HST audits annually. These audits represent one of the most common tax reviews businesses encounter. Collins Barrow’s experience shows a substantial increase in CRA’s GST/HST audit activities in the last year, especially when refund or rebate claims are involved.
The CRA has changed its strategy for small businesses with annual sales under $4 million. They now conduct separate GST/HST audits instead of combining them with income tax reviews. This change affects thousands of businesses, particularly those that must register for GST/HST after their income exceeds $30,000. Certain activities can trigger an audit quickly. These include reporting large sales or input tax credits (ITCs) during your company’s original years of operation.
Understanding CRA inspector’s priorities makes it easier to prepare for and handle the audit process effectively. This piece guides you through crucial preparation steps, common audit triggers, required documentation, and proven strategies to help you manage your next GST/HST audit with confidence.
Understanding GST/HST Audits
Canadian businesses often find GST/HST compliance challenging. The Canada Revenue Agency (CRA) made a big change in 2010. They split GST/HST audits from income tax audits and created a dedicated program to focus on these specific taxes. This change has substantially altered how businesses prepare for and handle their tax obligations.
What is a GST/HST audit?
A GST/HST audit works like a detailed checkup of your tax filings. The CRA takes a close look at your business records to make sure you collect, report, and remit GST/HST correctly. You can call it a financial health check where auditors review your sales records, invoices, and input tax credit (ITC) claims to see if they line up with Canada’s tax laws.
Auditors select files in two ways. The CRA uses risk assessment to spot possible non-compliance. They also pick files randomly to keep the tax system honest. Random selection happens, but most audits start because of red flags in filings or information from third parties.
Over the last several years, the CRA has stopped doing combined audits. Businesses now face either an income tax or GST/HST audit, not both at once. Auditors can now build specialized expertise and apply tax laws better. The CRA also reviews all GST/HST refund requests before approval. An examiner from anywhere in Canada might contact you as part of their national workload model.
Why CRA conducts these audits
GST/HST audits keep the tax system fair and consistent for everyone. These audits help the CRA find:
- Underreporting of GST/HST amounts
- Incorrect input tax credit claims
- Failure to charge or remit GST/HST appropriately
- Misclassification of taxable and non-taxable sales
The CRA’s GST/HST Audit and Examination Program goes beyond simple compliance checks. They help GST/HST registrants meet their tax obligations while measuring additional taxes owed when non-compliance happens.
The program also watches and assesses risk in new economic activities, especially in digital economy and cryptocurrencies. The CRA develops targeted compliance strategies for high-risk business segments and guides businesses on GST/HST compliance issues.
These audits help the CRA promote quality standards consistently. They also spot trends and learning needs that help businesses improve their compliance. These reviews serve as both enforcement tools and learning opportunities for businesses to build stronger tax management systems.
GST/HST meaning and scope
GST means Goods and Services Tax – a federal sales tax that applies to most goods and services sold in Canada. Many provinces have combined this with their provincial sales taxes to create the Harmonized Sales Tax (HST). This system forms the basis for business taxation and affects almost all commercial transactions.
Consumers might find it simple, but GST/HST can get “very complex, very quickly” according to the CRA. The biggest challenge lies in putting what you’re selling into the right category—whether it’s a good, service, real property, or intangible personal property. These categories determine which place-of-supply rules apply and what GST/HST rate to charge.
GST/HST-registered businesses can get back taxes paid on business purchases through input tax credits (ITCs) when filing returns. Usually, these credits equal 100% of the GST or HST paid on supplies for business activities, with some exceptions.
Good record-keeping and clear understanding of GST/HST rules help businesses maximize their returns. Keep detailed records of business spending all year and note exact GST/HST amounts. This makes tax returns easier and gives you peace of mind if you face an audit.

Top Triggers That Can Lead to a CRA Audit
You can avoid potential problems by knowing what makes the CRA start an audit. The Canada Revenue Agency doesn’t pick businesses randomly for GST/HST audits. They use advanced risk assessment systems and research to spot taxpayers who might not understand their tax duties. Any business could face an audit, but specific warning signs make it much more likely you’ll get that dreaded notice.
Large input tax credit (ITC) claims
GST/HST audits happen most often when you claim unusually high input tax credits compared to your business activity. The CRA might suspect something’s wrong if your ITC claims don’t match your revenue:
- You’re mixing personal and business expenses
- You’ve turned in fake or duplicate invoices
- Your claimed expenses don’t match what your business does
Businesses that get big refunds outside what’s normal for their industry often face extra review. Before approving any GST/HST refund requests, the CRA checks everything carefully to find mistakes or signs that rules aren’t being followed. You should keep detailed records of all business purchases and regularly check that expenses are properly classified to reduce your risk.
Discrepancies between GST/HST and income tax returns
Your GST/HST returns get compared with income tax filings by the CRA. Different numbers between these documents quickly raise questions about your bookkeeping. Auditors watch for:
- Sales numbers that conflict between tax filings
- Revenue reports that don’t match across T4 slips, invoices, and reported income
- Signs that suggest you’re not reporting all income
Simple mistakes often cause these differences rather than attempts to cheat. You should still make sure your sales and revenue numbers match across all tax documents to avoid unwanted attention.
Operating in cash-heavy industries
The CRA watches businesses that handle lots of cash more closely. They often target these industries:
- Restaurants and food service establishments
- Construction and skilled trades
- Auto repair and detailing shops
- Retail stores
- Transportation services
These sectors get extra attention because they’ve shown higher risks of unreported earnings historically. On top of that, businesses using electronic point-of-sale systems might be checked for “zappers” – software that can change or delete transactions to show lower sales.
Frequent losses or unusual deductions
The CRA quickly notices if you report business losses year after year while staying open. They might ask if you’re running a real business or just trying to write off hobby expenses as business costs.
Unusual deductions for your industry or business size also draw attention. The CRA measures your business figures against others in your industry. An audit might start if your numbers look very different – like having much lower taxable sales than usual.
Newly registered businesses
New GST/HST registrants face extra checks, especially if they report big sales or input tax credits right after starting. The CRA usually checks compliance in the first years to set good habits from the start.
New registrants who were small suppliers before registering can claim ITCs for GST/HST paid on supplies they already had. But claiming too many of these credits might trigger an audit.
Knowing these triggers won’t guarantee you’ll avoid an audit, but it helps you prepare better. Reach out to BOMCAS Canada for expert help with your GST/HST audit concerns.
The CRA Audit Process Explained
The CRA’s selection of your business for a GST/HST audit kicks off a step-by-step process with specific protocols. You need to know each step to guide you through this stressful situation confidently. My years of working with Canadian businesses have shown me how good preparation can change audit outcomes completely.
Initial contact and audit letter
The audit process usually starts when the CRA reaches out. You’ll get a call, mail, or both from an auditor telling you that your business needs a review. The caller’s identity might make you unsure at first. You can end the call politely and dial back using the official CRA number or wait for your letter in the mail.
Your first contact letter makes it official and includes key details:
- The tax years under review
- A detailed list of documents you need to provide
- Specific questions requiring your response
- The auditor’s contact information
This letter needs your full attention as it shows what the CRA wants to look into. After this first contact, your auditor might schedule a visit to your business or ask you to send documents online.
What documents are typically requested
The CRA needs complete documentation during GST/HST audits to check if your tax reporting is accurate. Audit specialists say you should get ready with:
- Banking records for all business accounts including statements
- Your detailed general ledger
- A complete listing of GST/HST collected and ITCs claimed
- Sales and purchase invoices
- Lease/purchase/sales agreements for any vehicles or capital assets
On top of that, auditors look at personal financial records that could affect your business operations, like personal bank statements, mortgage documents, and credit card statements. The auditor wants electronic records before meeting in person to speed up the process.
Security concerns prevent auditors from accepting records through email. Your auditor will tell you how to submit documents securely through CRA’s online services.
Timeline and deadlines
The CRA sets clear timelines for audit responses. You must provide all requested documentation within 30 days after getting the first request. These timelines might change based on:
- The complexity of the request
- Whether documents are located outside Canada
- The age of the tax years being examined
- If documents require complex retrieval methods
You can ask for more time if you face situations beyond your control like illness, death, natural disaster, or changing representatives. Remember that delays in providing information will make the audit longer and might raise new questions.
The time needed for the whole audit changes based on several things. Your record keeping, the audit’s scope, missing documentation delays, and talks with CRA tax specialists all play a part. Well-organized records and quick responses to the auditor cut down the review time substantially.
The process ends with an official letter about the findings and final reassessment. You have 90 days from the reassessment date to file a GST/HST objection if you disagree with the results.
BOMCAS Canada offers professional guidance through this complex process for all your GST/HST audit needs. Their expertise helps from first contact to final resolution.
How to Prepare Before the Audit Starts
Good preparation serves as your best defense against GST/HST audits. The old shoebox of receipts won’t cut it anymore—auditors expect well-documented records. Poor documentation usually leads to denied input tax credits and unfavorable audit results. Your business stands a better chance by taking action before receiving an audit notice.
Organize your financial records
The CRA requires businesses to keep proper books and records for at least six years from the end of the last tax year they relate to. This legal requirement covers both paper and electronic formats. Even with paper records, you need electronically readable versions of your accounting records.
Your documentation should include:
- Business finances separated from personal transactions to avoid reporting errors
- Clear categories for all income and expenses that anyone can reference
- Monthly bank and credit card statement reconciliation to spot problems early
- Receipts stored and labeled by date and type of expense
The goal is to create a system where you can find any document quickly. This setup meets CRA requirements and saves time during an audit.
Review past GST/HST filings
Self-audits work best to prevent compliance issues. Regular reviews help catch mistakes early and ensure you meet all business tax obligations.
While exploring your past filings:
- Make sure financial statements match your tax returns
- Check if GST/HST collected lines up with reported amounts
- Verify documentation for all input tax credits
- Watch for unusual patterns that might catch CRA’s attention
These reviews work better quarterly instead of yearly. This way, you can fix potential issues while details remain fresh in your mind.
Identify high-risk transactions
The CRA pays special attention to unique or large transactions during audits. Spotting these becomes crucial. You should flag:
- Large input tax credit claims outside your industry’s normal range
- Transactions with related parties
- Big one-time purchases or sales
- New areas like digital services or cryptocurrencies
A retail business that adds online sales to customers in different provinces needs extra attention. You must apply correct tax rates based on customer location and include complete addresses on invoices.
The CRA has become stricter during audits. They often deny ITCs claimed by corporations when documents show the owner personally as the recipient. Problems also arise when Company A receives an invoice for Company B’s commercial activities, then pays and claims the ITC.
Ensure proper tax rates were applied
Tax rate checks form a basic part of audit preparation. Tax requirements get more complex as businesses expand across provinces or internationally.
Your tax rate review should:
- Check correct GST/HST rates for each business location
- Validate supplier GST/HST registrations to avoid denied ITCs
- Test your point-of-sale system’s automatic rate application
- Keep clear records explaining special tax situations
You must not only collect the right amount but also document why specific rates applied to each transaction.
These preparation steps substantially improve your audit readiness. Professional guidance offers a great way to get through complex tax requirements. Contact BOMCAS Canada for all your GST/HST audits to ensure your business stays ready for CRA review.
What Happens During the Audit
A GST/HST audit moves through several distinct phases after the CRA picks your business to review. Getting a clear picture of what happens during this vital examination will help you handle the process confidently and professionally.
Phone interviews and document reviews
Phone interviews play a key role in the audit process. The CRA now holds broader powers to conduct oral interviews with taxpayers, including owner-managers and employees of an affected business. These interviews might seem casual, but they carry substantial weight in the audit findings.
Before any phone interview:
- Get all records and documents you might need handy
- Ask for questions ahead of time if possible
- Pick a time that works for you and your representatives
- Set up a quiet, private space for the call
The auditor will ask questions about your business operations and submitted documents during the interview. Note that your answers could expose you to penalties, higher assessments, or even criminal prosecution since these conversations happen without an official court record.
The auditor usually asks for electronic records before meeting you, which speeds up the audit. CRA auditors can’t accept email files due to security protocols, so they’ll give you secure online options to submit your documents. They’ll review various documents, including business records, business owners’ personal records, and possibly records from related individuals or entities.
On-site visits and what to expect
Auditors usually conduct on-site reviews at your home, business, or your representative’s office. The auditor will show valid ID when they arrive. Face-to-face meetings help resolve questions quickly and reduce audit completion delays.
Auditors might:
- Talk to accounting staff about business operations
- Look through family members’ records if relevant
- Copy electronic records or borrow physical documents (giving you a detailed receipt)
- Compare your sales data with ITC claims
- Search for gaps in tax preparation documents
Your cooperation and transparency make the audit run smoother. A professional and well-organized environment shows the CRA you take compliance seriously and helps everyone work more efficiently.
How to communicate with the auditor
Good communication with your auditor shapes the outcome. The CRA expects you to answer questions honestly and provide requested records promptly. A collaborative approach makes the audit more efficient.
You might want a tax professional present during interviews. A Canadian tax lawyer can help answer questions and step in if an auditor asks about privileged information or inappropriate questions. Their presence ensures the CRA only asks for relevant and reasonable information.
Your communication should be:
- Professional and respectful yet strategic
- Quick to respond to information requests
- Clear about business processes without giving too much detail
- Backed by professional help when needed
If you couldn’t provide certain details during the interview, send written answers to pending questions. The auditor will set up time to discuss any questions that come up while reviewing your documents.

Common Documentation You Must Have Ready
Good documentation is the foundation of a successful GST/HST audit defense. The CRA gets into specific records during these reviews. Some documents carry more weight than others. Your audit experience can improve when you have these four types of documentation available and well-organized.
Invoices and receipts
You must provide documentation that proves GST/HST payment on expenses to claim an Input Tax Credit (ITC). Your supporting documents need five vital elements: your supplier’s name and GST/HST registration number, invoice date, total supplies amount with tax paid, description of supplies/services received, and payment terms.
Requirements become stricter for purchases over $696.68. On top of that, your customer invoices must clearly show if GST/HST is part of the price or added separately. You need to show the full HST rate as one percentage instead of splitting it into federal and provincial parts. Your customers who are GST/HST registrants need this documentation to support their ITC claims.
Bank statements and ledgers
GST/HST auditors look at both business and personal financial records. These include ledgers, journals, invoices, receipts, bank statements, and expense reports. The CRA might review business owner’s personal bank statements, mortgage documents, and credit card statements.
Records of spouses, family members, and related entities like corporations or partnerships may also face scrutiny. Complete, accurate, and properly settled financial records are significant. Even senior-level employees must have appropriate sign-off for every expense claim.
Contracts and agreements
Written agreements and contracts serve as strong documentary evidence in tax disputes. These documents help you report income and expenses correctly and validate claimed expenses. Poorly written contracts—or not following their terms—can hurt your position during an audit.
The CRA might ask anyone who signed a contract for information or question them in tax court. Limited evidence supports your tax position without written agreements. Some cases need extra material beyond primary documentation—a service contract might list supplier and recipient details while separate invoices show consideration and tax amounts.
Expense reports with tax details
CRA requirements demand specific tax information in your expense reports. Each receipt should display purchase date, seller’s details, your information, a detailed description of purchases, and GST/HST payment information.
Vehicle expense records must show total kilometers driven and business-related kilometers. Business owners should keep these records for at least six years from the last related tax year’s end. Every expense needs a valid business reason and receipts with all required tax details.
BOMCAS Canada can help ensure your documentation meets CRA standards for all your GST/HST audits.
Post-Audit: Understanding the Results
The final steps after your GST/HST audit are vital to protect your business interests. This phase determines if you’ll need to pay more taxes or if your filings check out correctly.
Receiving the reassessment letter
After completing their examination, the CRA sends an official letter that outlines their findings and final reassessment. The document will show one of these outcomes:
- The assessment may be vacated (completely reversed)
- A reassessment may be made (objection allowed wholly or partially)
- The assessment may be confirmed (original assessment upheld)
- An upward reassessment may occur (increasing GST/HST collectible or decreasing ITCs)
This document needs your careful review since it contains significant information about the CRA’s decision and serves as the foundation for any future actions.
How to file a GST/HST objection
You have the right to dispute the results if you disagree with the reassessment. Here’s how to formally contest a GST/HST reassessment:
- Complete Form GST159 (Notice of Objection for GST/HST)
- Submit the form to the Chief of Appeals at your designated appeals intake center
- Include detailed reasons that explain why you think the assessment is incorrect
The CRA assigns an appeals officer to your case after receiving your objection. This officer will review the assessment based on your provided information. The appeals officer will then decide to vacate, vary, or confirm the reassessment.
Timelines for appeals
Time limits play a vital role in tax disputes. The CRA must receive your objection within 90 days from when they mailed your reassessment. You can ask for an extension up to one year after the normal deadline if you miss it.
You can take your case to the Tax Court of Canada within 90 days if you disagree with the objection review decision. You also have the right to appeal if the CRA hasn’t made a decision within 180 days from your GST/HST objection filing date.
The Tax Court gives you two options for appeals:
- Informal Procedure – for disputed amounts under $69,668.01 with no filing fee
- General Procedure – for larger amounts with filing fees between $348.34 and $766.35
BOMCAS Canada can help guide you through your GST/HST audits. We’ll help you handle these post-audit challenges and meet all important deadlines for objections or appeals.
Tips to Avoid Future GST/HST Audits
You can take steps to prevent GST/HST audits by being proactive rather than reactive. While no business can completely avoid an audit, we can reduce the risk by a lot through specific strategies.
Maintain consistent records
Good record-keeping is the foundation of GST/HST compliance. The CRA requires businesses to keep all records for six years from the end of the last tax year they relate to. Your documentation system should include:
- Sales invoices with proper GST/HST registration numbers
- Purchase receipts showing tax paid
- Detailed financial statements reconciled monthly
- Digital copies of all tax-related documents
It’s worth mentioning that bank statements alone won’t prove your expenses—you need actual receipts or invoices from vendors that include their GST/HST numbers to claim ITCs.
Use automated accounting tools
Digital accounting solutions make GST/HST compliance much more accurate. CRA-approved accounting software helps businesses:
- Calculate correct GST/HST amounts based on jurisdiction automatically
- Track input tax credits with proper documentation
- Generate compliant financial reports for tax filings
- Keep audit-ready records
QuickBooks and Xero are great tools that help Canadian businesses manage tax filing and meet CRA compliance requirements with their GST/HST tracking features. These tools cut down on manual errors that often trigger audits and help maximize legitimate input tax credit claims.
Work with a tax professional
Tax professionals are a great way to get protection against audit triggers. Tax specialists can:
- Review internally to spot potential compliance issues
- Set up monthly reconciliation routines
- Improve processes to fix compliance gaps
- Represent you professionally during audits
A CPA makes sure everything follows CRA regulations properly. This lets you focus on growing your business while keeping your finances accurate.
BOMCAS Canada can help with all your GST/HST audits. We’ll help your business stay compliant and reduce audit risks through professional guidance.
