Before December 31 arrives, make sure your business finances are ready for the year ahead.
Running a small business in Alberta means juggling customers, projects, expenses, and countless daily responsibilities. With everything going on, reviewing your finances before year-end can easily slip down the priority list.
But the final weeks of the year are an important opportunity to get organized, identify potential bookkeeping issues, and prepare for your upcoming tax obligations.
Whether you're a contractor, tradesperson, sole proprietor, or growing business owner, a little preparation now can help you avoid unnecessary surprises later.
At Ask-Her® Tax + Bookkeeping Inc., we help Alberta business owners understand their numbers, stay organized, and approach tax season with greater confidence.
Here's what you should review before closing out 2026.
What Should Alberta Small Business Owners Do Before the End of 2026?
The most important year-end tasks include reconciling business accounts, reviewing income and expenses, organizing receipts, checking GST obligations, and identifying outstanding tax responsibilities.
For businesses operating on a December 31 year-end, these steps help ensure financial records accurately reflect the 2026 tax year.
Corporations may have a different fiscal year-end, so their deadlines and reporting periods can vary.
1. Make Sure Your Bookkeeping Is Up to Date
Start by reviewing your financial transactions for the year.
Are all business purchases recorded? Have deposits been categorized properly? Do your accounting records match your bank and credit card statements?
Incomplete bookkeeping can make it difficult to determine how much your business actually earned or spent.
Before year-end, take time to:
Reconcile your business bank and credit card accounts.
Record any missing income or expenses.
Review uncategorized transactions.
Investigate duplicate or incorrect entries.
Separate personal and business transactions.
Accurate bookkeeping provides the foundation for reliable financial reports and tax preparation.
If you're several months behind, addressing the problem now is usually more manageable than leaving everything until filing season.
2. Review Outstanding Invoices and Unpaid Bills
An important part of year-end bookkeeping is understanding what your business has earned and what it still owes.
Review unpaid customer invoices, outstanding supplier bills, and any deposits or advance payments received.
Most Canadian businesses report income using the accrual method of accounting. This generally means reporting income when it is earned, even if the customer hasn't paid yet.
Eligible business expenses are generally recorded when incurred, subject to applicable tax rules.
Why does this matter?
Your bank balance might look healthy, but it doesn't necessarily show outstanding obligations, unpaid invoices, or your actual profitability.
Reviewing these transactions helps create a more accurate financial picture before year-end.
3. Organize Your Business Expenses and Receipts
Missing receipts and incorrectly categorized expenses can create headaches when preparing your tax return.
Before December 31, review your business purchases and make sure you have appropriate supporting documentation.
Common categories worth checking include:
Office supplies and business software.
Advertising and marketing expenses.
Business insurance and professional fees.
Eligible vehicle and travel expenses.
Equipment and business-related purchases.
Eligible home office expenses.
Not every purchase is immediately deductible, and personal expenses cannot be claimed simply because they were paid through a business account.
Equipment and other capital purchases may be subject to different tax treatment than regular operating expenses.
The goal isn't to claim as much as possible without reviewing the details. It's to ensure legitimate business expenses are accurately documented and classified.
For guidance, review the Canada Revenue Agency's business expense information.
4. Check Your GST Registration and Filing Obligations
GST responsibilities can become more complicated as your business grows.
For most businesses, the CRA's small-supplier threshold is $30,000 in taxable revenue over a single calendar quarter or four consecutive calendar quarters. The timing of registration depends on how the threshold is exceeded, and special rules can apply.
The $30,000 threshold refers to qualifying revenue, not business profit.
If your business is registered for GST, review whether:
GST collected has been recorded correctly.
Eligible input tax credits are supported by appropriate documentation.
Previous returns and payments are up to date.
Your reporting frequency and upcoming deadlines are understood.
Staying on top of GST obligations throughout the year can help prevent unexpected balances or filing problems.
Learn more from the CRA's GST registration guidelines.
5. Review Your Business Vehicle Expenses
If you use your vehicle for business, now is a good time to review your mileage records.
For vehicles used for both personal and business purposes, only the eligible business-use portion of applicable expenses can generally be deducted.
The CRA expects supporting records, including the total distance driven and business kilometres.
Your mileage log should document the dates, destinations, purposes, and distances of business trips.
It's much easier to maintain accurate records throughout the year than to reconstruct months of travel later.
6. Review Inventory and Equipment Purchases
If your business sells products or maintains inventory, review the items you have on hand at year-end.
Inventory records can affect the calculation of your cost of goods sold and net business income.
For contractors and other businesses, it's also worth reviewing equipment purchases and significant business assets.
A common misconception is that buying expensive equipment before December 31 automatically creates an immediate deduction for the entire purchase price.
In reality, capital purchases can be subject to specific rules, including capital cost allowance and other applicable provisions.
Before making a significant purchase primarily for tax reasons, consider whether it genuinely benefits your business and discuss the potential tax treatment with a qualified professional.
7. Review Payroll and Contractor Payments
If your business has employees, review your payroll records before year-end.
Confirm that employee information, wages, deductions, benefits, and required remittances have been recorded accurately.
If you work with subcontractors, ensure their invoices and payments are properly documented and determine whether any information-reporting obligations apply.
Payroll corrections are often easier to identify before annual slips and returns are prepared.
8. Estimate Your Tax Obligations
One of the biggest financial surprises for small business owners is discovering they owe more tax than expected.
Your business can generate strong sales without necessarily setting aside enough money for income taxes, GST, or other obligations.
Before year-end, review your estimated taxable income and discuss whether additional planning is appropriate.
For sole proprietors, business profits generally flow through to their personal income tax returns.
Corporations have separate tax filing and payment responsibilities.
Understanding these differences can help you plan your cash flow more effectively.
9. Know Your Important 2027 Tax Deadlines
Getting organized also means knowing when your returns and payments are due.
For the 2026 tax year, the CRA identifies these important deadlines:
Tax obligationGeneral deadlineSelf-employed income tax returnJune 15, 2027Self-employed income tax balance owingApril 30, 2027Corporate income tax returnWithin six months of fiscal year-endCorporate income tax balanceGenerally two months after year-end, or three months for qualifying corporationsGST annual returnGenerally three months after the reporting year-end, with exceptions
Important: Some self-employed individuals have different filing deadlines. Eligible annual GST filers who are self-employed with a December 31 fiscal year-end generally have until June 15, 2027 to file their GST return, but must pay any balance owing by April 30, 2027.
Deadlines can also change when they fall on a weekend or recognized holiday.
For the latest requirements, consult the CRA's 2027 business tax deadlines.
10. Make a Plan for the Year Ahead
Year-end preparation isn't just about satisfying tax requirements.
It's also an opportunity to better understand your business.
Take a look at your revenue, operating expenses, cash flow, and overall profitability.
Ask yourself:
Which parts of my business performed best this year?
Are certain expenses increasing faster than revenue?
Do I have enough cash set aside for upcoming obligations?
Are my bookkeeping processes keeping up with business growth?
What should I improve heading into 2027?
Clear financial information helps you make decisions based on actual numbers rather than assumptions.
And if your books are disorganized, this is an ideal time to address the problem before another year begins.
Frequently Asked Questions About Small Business Taxes in Alberta
What is the year-end tax checklist for an Alberta small business?
A small business year-end tax checklist should include reviewing financial records, reconciling accounts, organizing receipts, verifying GST obligations, checking outstanding invoices, reviewing expenses, and preparing for upcoming tax deadlines.
The exact requirements depend on the business structure and fiscal year-end.
Do Alberta sole proprietors have to file taxes by April 30, 2027?
Generally, self-employed individuals have until June 15, 2027 to file their 2026 income tax returns, subject to exceptions. However, any outstanding income tax balance is generally due by April 30, 2027.
Can I claim business expenses paid with my personal credit card?
Yes, eligible business expenses may still be deductible when paid using a personal credit card, provided the business purpose and appropriate documentation are established.
The transactions must also be properly reflected in your bookkeeping to avoid omissions or duplicate claims.
How long should Alberta business owners keep their tax receipts?
The CRA generally requires business records and supporting documents to be kept for at least six years from the end of the last tax year to which they relate. Certain records may need to be retained longer.
What if my business bookkeeping is behind at year-end?
Start by gathering bank statements, invoices, receipts, and other financial documents. Identify missing transactions and reconcile your accounts.
If your records are significantly behind, a professional bookkeeping clean-up can help you establish a more accurate financial picture before preparing tax returns.
Does every Alberta business have a December 31 fiscal year-end?
No. While individuals generally use a calendar tax year, corporations can have different fiscal year-ends. Your tax deadlines and year-end tasks should align with your applicable reporting period.
