Understanding T4/T5 Slips in Alberta, Saskatchewan, and BC: Deadlines, Filing Steps, and Common Mistakes

If you pay employees or shareholders, T4 and T5 slips are non-negotiable. Each February, many Alberta, Saskatchewan, and BC business owners scramble to figure out who needs what, which boxes to fill, and how to file on time. Mistakes can lead to penalties and amended returns. This guide breaks down T4/T5 basics in plain language-so you can file confidently and avoid surprises.

At Big Country Accounting Group in Calgary, we help owner-managed companies and families align payroll, dividends, and tax planning so compliance is seamless. Whether you manage it in-house or want hands-off support, this article gives you the steps you need now.

T4 vs. T5: What’s the Difference?

T4 (Statement of Remuneration Paid): Reports employment income and related payroll deductions.

T5 (Statement of Investment Income): Reports passive income such as dividends and interest paid to individuals or corporations.

Who needs a T4?

Employees (full-time, part-time, seasonal, casual)
Owners/directors on payroll
Anyone who received taxable benefits (e.g., auto, group insurance, allowances)

Who needs a T5?

Shareholders who received dividends
Lenders or shareholders who received interest
Other recipients of investment income paid or credited by your business

Note: If you paid or credited $50 or more of interest or dividends in the year, you generally need to issue a T5. Even below $50, recipients still must report the income.

Deadlines and How to File

Deadline: File T4s and T5s and deliver copies to recipients by the last day of February following the calendar year.

Electronic filing: Required if you file more than 50 slips. Recommended for everyone to reduce errors.

How to file:

CRA Web Forms or Internet File Transfer via My Business Account – Payroll software that generates XML files – Mail (slower and more error-prone)
Penalties apply for late, missing, or incorrect slips and summaries. They accrue per day and scale with the number of slips, so don’t leave this to the last minute.

What Information Goes on Each Slip?

T4 highlights

Employment income (salary, wages, bonuses)
Taxable benefits (e.g., employer-paid premiums, automobile benefits)
Income tax deducted, CPP/QPP pensionable earnings and contributions, EI insurable earnings and premiums
Union dues and other deductions, if applicable

Tip: The total of your payroll remittances (PD7A statements) should reconcile to the T4 Summary. If it doesn’t, you likely missed a benefit or misclassified an amount.

T5 highlights

Dividends: Eligible and non-eligible amounts, plus corresponding dividend tax credit amounts
Interest: Paid or credited to recipients, including to shareholders or related parties’ other investment income: As applicable under CRA T5 Guide

Tip: Dividends to non-residents usually require NR4, not T5. Ask before you file.

Step-by-Step: How to Prepare Accurate T4/T5 Slips

Decide on remuneration mix early

For owners, plan salary vs. dividends with your accountant before year-end. The right blend can optimize CPP, RRSP room, and overall corporate tax planning.

Gather records and reconcile

Payroll registers, taxable benefits calculations, PD7A statements – For T5s, dividend resolutions, minute book entries, and interest schedules

Calculate taxable benefits correctly

Common items: auto standby charge/operating cost, employer-paid life and health premiums, cell phone plans – Use CRA guidance or payroll software; document your calculations

Check year-to-date totals

Confirm gross pay equals T4 employment income – Ensure CPP/EI amounts match thresholds and your remittances

Prepare slips and summaries

Use CRA Web Forms if you don’t have payroll software – Review recipient names, addresses, and SINs/BNs for accuracy

File and distribute

File electronically and provide employee/shareholder copies by the deadline – Keep proof of delivery (secure portal, email with read receipt, or mailed copies)

Document and retain records

Keep worksheets, resolutions, and reconciliations for at least six years

Common T4/T5 Mistakes (and How to Avoid Them)

Misclassifying workers as contractors: If they’re really employees, they need a T4 and source deductions. When in doubt, ask.

Forgetting taxable benefits: Auto, allowances, and premiums are often missed, creating CPP/EI and tax discrepancies.

Not issuing a T5 for shareholder interest: Interest on shareholder loans is investment income and may require a T5.

Mixing up eligible and non-eligible dividends: The type affects the dividend tax credit and must be recorded correctly.

Paying late or filing late: This triggers penalties and may draw attention to your file. Paying non-residents: Might require withholding and NR4 reporting—not a T5.

Practical Tips You Can Apply Today

Use a year-end checklist: Employees list, benefit summaries, bonuses paid, and shareholder distributions.

Reconcile monthly: With Calgary bookkeeping services or internal processes, reconcile payroll and dividends each month so February isn’t a scramble.

Standardize dividend documentation: Prepare resolutions at the time of payment, not at year-end.

Keep shareholder loan ledgers: If you charge or pay interest, track it and accrue it properly to avoid surprise T5s.

Run a test file: If your software allows, validate your T4/T5 XML files early to catch errors.

Plan ahead: Book a January meeting for tax planning to finalize salary vs. dividend amounts.

Real-World Example: How We Help

A Calgary trades company with 12 employees and two owner-managers paid bonuses in December and dividends in January. Their internal spreadsheet missed auto benefits and under-reported CPP.

We filed compliant T4s, prepared T5s for the dividends, and aligned the remuneration mix through proactive tax planning.

The result: no penalties, accurate filings, and insights to improve cash flow in the new year.
