Bookkeeping Onboarding Checklist for New Businesses (2026)
Everything a new Canadian business needs to get its bookkeeping function running correctly from day one — CRA Business Number registration, the $30,000 GST/HST threshold, dedicated bank accounts, chart of accounts setup, and the record-keeping habits that save real time and money later.
1. Why the Order of These Steps Actually Matters
(cite index="32-1">A new business bookkeeping setup should not be rushed or left until tax season. Clean bookkeeping starts with the basics: business registration details, separate bank accounts, a proper chart of accounts, GST tracking, payroll setup, receipt organization, record keeping, and monthly reconciliations.

2. Step 1: Register for Your CRA Business Number (BN)
(cite index="35-1">The CRA business number is a nine-digit identifier used for all your dealings with the CRA — filing taxes, collecting GST/HST, remitting payroll deductions, importing goods, and more. Many new business owners try to use their personal SIN for business taxes, but the CRA requires a separate BN for business activities.
3. Step 2: Add the Right Program Accounts to Your BN
(cite index="35-1">The BN is the root number for all your CRA program accounts — if you start with just a GST/HST number but later hire employees, you add a payroll account to the same BN. The most common accounts are GST/HST and payroll.
4. Step 3: Understand the $30,000 GST/HST Threshold
(cite index="30-1">If your business earns more than $30,000 in revenue over four consecutive calendar quarters, you must register for a GST/HST number and begin collecting and remitting GST/HST. Even below the threshold, voluntary registration can be beneficial because it allows you to claim input tax credits (ITCs) on business expenses.

5. Step 4: Open a Dedicated Business Bank Account
6. Step 5: Set Up Your Chart of Accounts
(cite index="34-1">A Chart of Accounts is the categorized list of every account in the general ledger — assets, liabilities, equity, revenue, and expenses. Each main category is divided into sub-ranges (e.g., 1000-1099 = Cash, 1100-1199 = Accounts Receivable). (cite index="34-1">CRA does not mandate a specific Chart of Accounts — most accounting software handles GIFI mapping automatically.
7. Step 6: Build Dedicated GST/HST Accounts Into the Chart
8. Step 7: Choose and Configure Your Accounting Software
Once your BN, GST/HST registration status, bank account, and basic chart of accounts are in place, the next step is configuring your actual accounting software — company profile, chart of accounts import, GST/HST setup, bank feeds, and payroll integration if applicable. See our dedicated guide on the bookkeeping software setup checklist for the full step-by-step configuration process once these foundational pieces are ready.
9. Step 8: Organize Your Business Setup Documents
(cite index="32-1">Keep a simple folder for your business setup documents, including registration papers, incorporation documents, CRA business number details, GST account information, payroll account information, insurance, lease agreements, loan documents, and major contracts.
10. Step 9: Know Your Record-Keeping Requirements
| Requirement | Details |
|---|---|
| Types of records required | (cite index="30-1">Sales invoices, purchase receipts, bank statements, contracts, payroll records, GST/HST returns |
| Location | (cite index="30-1">Records must be kept at your place of business in Canada (or with CRA permission, elsewhere) |
11. Step 10: Set Up Training and Education Expense Tracking From Day One
12. Step 11: Establish Monthly Bookkeeping Habits
- (cite index="29-1">Record every transaction — income, expense, transfer, payroll — all of it. Categorise as you go using your chart of accounts.
- (cite index="29-1">Track GST and PST separately — set up sub-accounts for tax collected and tax paid so filing takes minutes, not hours.
- (cite index="29-1">File GST/HST and PST on schedule.
13. DIY vs. Professional Bookkeeping: When to Make the Switch
(cite index="29-1">DIY makes sense for sole proprietors with under 50 monthly transactions, no employees, and no GST registration. Once you have employees, GST/PST registration, or 50+ monthly transactions, the cost of professional bookkeeping is almost always worth it.
14. The Complete Onboarding Checklist
- Register for your CRA Business Number through Business Registration Online (phone registration no longer accepted)
- Add the correct program accounts to your BN (GST/HST, payroll, as applicable)
- Track taxable revenue against the $30,000 GST/HST threshold from your first sale
- Open a dedicated business bank account (and ideally a business credit card) before your first transaction
- Set up a chart of accounts customized for your industry, including dedicated GST/HST sub-accounts
- Configure your accounting software's company profile, bank feeds, and tax settings
- Organize a central folder for all business setup documents
- Confirm your record-keeping location and retention practices meet CRA requirements
- Set up a dedicated training and education expense category from your first month of operation
- Establish a monthly rhythm: record transactions continuously, reconcile monthly, file GST/HST on schedule
15. Common Onboarding Mistakes
- Using a personal bank account for business transactions: This creates real complications at reconciliation and in the event of a CRA review.
- Waiting until revenue is already well past $30,000 to register for GST/HST: This can create retroactive collection obligations the business didn't anticipate.
- Skipping dedicated GST/HST accounts in the chart of accounts: This forces manual reconstruction of every return each filing period.
- Treating bookkeeping setup as a tax-season task: Clean bookkeeping starts with the basics in the first 30 days, not reconstructed in April.
- Not tracking training expenses separately from the start: This buries a legitimate, often substantial deduction inside general overhead where it's easy to under-claim.

16. Frequently Asked Questions
What is the very first bookkeeping step a new Canadian business should take?
Register for a CRA Business Number (BN) before any other setup step, since the BN is the root identifier for every subsequent program account — GST/HST, payroll, and corporate tax all attach to this same number. Many new owners mistakenly try using their personal SIN, which creates confusion. As of November 3, 2025, the CRA no longer accepts BN and program account registrations by phone — registration must be completed through Business Registration Online.
At what revenue level does a new Canadian business need to register for GST/HST?
A business must register once taxable revenue exceeds $30,000 in any single calendar quarter or over four consecutive quarters — this is mandatory, and crossing it without registering can create retroactive collection obligations. Even below the threshold, voluntary registration can be beneficial since it allows claiming input tax credits on business purchases. Track taxable revenue against this threshold from the first sale, not just at year-end.
Why does a new business need a separate business bank account instead of just using a personal account?
A dedicated business bank account is one of the most important early steps, since commingling personal and business transactions makes bookkeeping significantly harder, obscures true profitability, and creates complications if the CRA reviews the records. A clean separation from day one means every transaction in the business account is presumptively a business transaction, dramatically simplifying bookkeeping and reconciliation.
What should a new business's chart of accounts include from the start?
A chart of accounts is the categorized list of every general ledger account — assets, liabilities, equity, revenue, expenses. Most software provides a default chart to customize for your industry. At minimum, include dedicated GST/HST accounts (payable, recoverable, and net owing), since skipping these means manually reconstructing every GST/HST return each filing period. CRA doesn't mandate a specific structure; software typically handles GIFI mapping automatically.
Should a new business track its own startup training and education expenses as a specific bookkeeping category?
Yes. Many new owners invest in courses, certifications, and professional development — often around back-to-school season — before and during their first year. These training expenses and related education deductions should get a dedicated expense category from the first month, not get buried in general operating costs. Properly documented training expenses incurred to earn business income are generally deductible, and tracking from day one makes claiming the full deduction far easier than reconstructing receipts later.
17. Final Thoughts
Getting bookkeeping right from a new business's very first transaction isn't about perfectionism — it's about avoiding the much larger cost of reconstructing a messy year of commingled accounts, missed GST/HST registration timing, and unorganized receipts right before a tax deadline. Registering your BN through Business Registration Online, tracking the $30,000 GST/HST threshold from day one, separating business and personal finances immediately, and building a chart of accounts with proper tax sub-accounts and a dedicated training expense category — these eleven steps, done in order, turn bookkeeping onboarding from a source of year-end stress into a foundation that actually supports the business as it grows.
