What is a T4A and When Do Calgary Contractors Receive It?
A T4A slip is a Canadian tax form used to report various kinds of non-employment income, including fees for services paid to independent contractors.[1][3] For contractors, the key box is usually Box 048 – Fees for services, which shows the total gross amount a client paid you during the year.[1][4] Unlike a T4, there is no employer–employee relationship and generally no source deductions for income tax, CPP, or EI.
Under CRA rules (Income Tax Regulations, often applied with reference to Box 048), businesses must issue a T4A if they pay $500 or more in a year to a contractor for services.[4][9] That means if a Calgary home builder pays a drywall contractor $18,000 in 2025, they must issue a T4A with the full amount in Box 048 for the 2025 tax year.
For Calgary contractors T4A tax filing 2026, the key timing points are:
- Income year: Calendar year 2025
- T4A issuance and filing deadline: February 28, 2026[2][9]
- Contractors typically get their T4A from each client by the end of February.
Importantly, CRA requires that the gross amount paid be reported; that usually includes sales tax if it formed part of the total payment.[1] You do not deduct your business expenses on the T4A itself—those are claimed on your own return.
Common Calgary examples:
- A Kensington marketing consultant bills a local restaurant $3,000 + GST monthly. The restaurant issues a T4A showing the annual gross amount in Box 048.
- A self‑employed electrician in Mahogany gets T4A slips from two general contractors plus additional cash jobs not on T4A. All of it is taxable business income.

Step-by-Step: How to File 2025 T4A Income in 2026
If you are self‑employed, CRA expects you to report all business income—both on and off T4A—using Form T2125 – Statement of Business or Professional Activities.[6] This is attached to your T1 personal tax return under the Income Tax Act.
Step 1 – Gather Your Income Slips and Records
- All T4A slips Calgary clients issued (Box 048 for contractor fees)
- Any invoices, e‑transfers, or cash income not reflected on T4A
- Bookkeeping reports from QuickBooks, Wave, or spreadsheets
Total all business income, including non‑T4A amounts. The CRA expects gross income to be reported under s. 9 of the Income Tax Act, which defines business income.
Step 2 – Complete Form T2125
On Form T2125, you will:
- Enter your business name and Calgary address
- Report gross professional or business income (T4A + non‑T4A)
- List all business expenses (vehicle, home office, supplies, etc.)
- Calculate net business income, which flows to your main tax return
This is where most contractor tax deductions Alberta are claimed.
Step 3 – Report CPP Contributions
As a self‑employed person, you must pay both employer and employee portions of CPP contributions, governed by the Canada Pension Plan and referenced in the Income Tax Act through s.118.7 (CPP credit). The calculation is done on Schedule 8 of your T1.
Step 4 – File Electronically
File via:
- NETFILE‑certified tax software, or
- A professional Calgary CPA firm like Tax Buddies using EFILE
Electronic filing reduces processing time and errors, which is particularly helpful for complex Calgary contractors T4A tax filing 2026 situations.
Step 5 – Keep Records
Under Income Tax Act s.230(4), you generally must keep books and records for at least six years. Maintain:
- T4A slips
- Invoices and receipts
- Mileage logs
- Bank and credit card statements
These support your income and deduction claims in case of CRA review.

Tax Rate Overview and T4A Income Impact in Alberta
While Tax Buddies Calgary will tailor planning to your exact income level, it helps to understand how your T4A income interacts with federal and Alberta provincial tax rates.
Simplified 2025 Personal Tax Brackets (Approximate)
Your T4A income from contracting is added to any other income (T4 wages, investment income, rental profits) to arrive at total taxable income. Proper contractor tax deductions Alberta and CPP planning can significantly affect your final bill.
Example:
A Calgary plumbing contractor earns:
- $90,000 in T4A income (gross)
- Claims $35,000 in legitimate business expenses
- Net business income: $55,000
This positions them in the lower bracket and may free up cash for RRSP contributions, which can further reduce taxable income.
For self‑employed taxes Calgary, coordinating T4A income with RRSP contributions, spousal income, and incorporation decisions is an area where a CPA can provide significant value.

Audit‑Proofing Your T4A Income: CRA Risk Reduction Tips
Receiving a T4A does not automatically trigger a CRA audit, but self‑employment is inherently higher risk in CRA’s eyes because you control both income reporting and deductions. Good habits can make Calgary contractors T4A tax filing 2026 far safer.
Practical CRA Audit‑Prevention Tips
1. Match All Reported Slips
CRA’s systems cross‑match T4A slips issued by your clients with your tax return. If a slip shows $60,000 and your return only reports $40,000 of income, an automatic review is likely. Make sure:
- All T4A amounts are fully included in gross income.
- You add any additional income not reported on slips.
2. Keep Clean, Organized Records
Maintain:
- Separate business bank account for contractor work.
- Digital copies of receipts (scanned or photographed).
- Mileage logs for vehicle use (dates, destinations, purpose).
This supports your deductions under CRA’s general record‑keeping requirements and Income Tax Act s.230.
3. Be Reasonable with Deductions
CRA looks for unusually high expense ratios (e.g., claiming 90% of home expenses or a large loss year after year). Ensure:
- Home office percentage is realistic (e.g., dedicated room, measured square footage).
- Vehicle business‑use percentage matches your logs.
- Meals are correctly limited to 50% where required.
4. Avoid Mixing Personal and Business
Try not to pay personal expenses from your business account or vice versa. If you must, clearly record shareholder draws or owner withdrawals in your bookkeeping.
5. Work with a CPA for Complex Files
If you have large T4A income, multiple clients, or are considering incorporating, a Calgary CPA can help structure your affairs and prepare solid, audit‑ready filings.

FAQ: T4A Slips and Self‑Employed Taxes in Calgary
1. I’m a Calgary contractor and only one client issued a T4A. Do I still report other income?
Yes. CRA expects you to report all business income, not just amounts on T4A slips, on Form T2125.[6] Cash jobs, e‑transfers, and invoices without T4As are still taxable.
2. What if my T4A slip is wrong or missing?
If the amount is clearly wrong, contact the payer and request an amended T4A.[1] If you cannot get a corrected slip before filing, use your own accurate records to report the correct income and keep documentation in case CRA asks.
3. Do I pay CPP or EI on T4A income?
You generally pay CPP contributions as a self‑employed person via Schedule 8, but you are not typically eligible to pay into EI unless you opt into a special self‑employed EI program. CPP is based on your net business income after expenses, within annual limits set under the Canada Pension Plan.
4. Do I charge GST/HST on my contractor invoices in Calgary?
If your worldwide taxable supplies exceed $30,000 in a 12‑month period, you must register and charge GST (5% in Alberta) under Excise Tax Act s. 240. The T4A usually includes the gross amount paid (service plus GST) when reported by the payer, while you report GST separately on your GST return.
5. Is it better to stay as a sole proprietor or incorporate my Calgary contractor business?
It depends on income level, risk, and long‑term plans. Higher and more stable income may benefit from incorporation, which introduces corporate tax rates and deferral opportunities. This decision goes beyond Calgary contractors T4A tax filing 2026 and should be reviewed with a local CPA.
