Ask a Calgary business owner what payroll costs them and most will name a software subscription. Forty dollars a month, maybe sixty with the add-ons. It sounds like a solved problem.
It rarely is. The subscription is the smallest line in the calculation, and it is the only one that appears on a statement. Everything else, the hours, the year-end scramble, the cost of getting a remittance wrong sits off the books, which is precisely why it goes unexamined for years.
Here is the full arithmetic, using 2026 figures, for a business of the size most Calgary firms actually are.
The Alberta advantage — and exactly where it ends
Alberta employers genuinely do have it easier than most of the country. There is no provincial sales tax to administer. There is no provincial payroll health levy of the kind British Columbia applies once B.C. remuneration passes $1,000,000. The general minimum wage has sat at $15.00 an hour since 2018, with a $13.00 rate for students under 18 in defined circumstances, so the annual re-costing exercise that occupies employers in other provinces simply does not arise here.
That advantage is real, and it is also narrower than it looks. Every federal obligation applies in full. Alberta employers calculate CPP against the same $74,600 ceiling as everyone else, contribute to the CPP2 band up to $85,000 at 4.00%, and pay EI at $2.28 per $100 of insurable earnings up to $68,900. They face the same remittance deadlines and the same penalty schedule.
In other words: Alberta removes a layer of provincial administration. It does not reduce the federal compliance load at all, and the federal load is where the expensive mistakes live.
Building the honest in-house number
Take a Calgary business with eight employees, semi-monthly pay, a couple of people on commission, and an owner or office manager handling payroll personally.
| Cost component | Realistic annual figure | Note |
| Payroll software | $600 – $1,400 | Scales with headcount and add-on modules |
| Processing time | $3,000 – $5,200 | 3–4 hrs per semi-monthly run at a loaded $40–$55/hr |
| Year-end and T4 season | $800 – $1,600 | Reconciliation, slips, summary, employee questions |
| CRA correspondence and corrections | $300 – $900 | Assumes no penalty — queries only |
| Total, clean year | $4,700 – $9,100 |
The processing-time line is the one the owners resist. Three to four hours per run sounds high until you count what is actually in it: collecting and checking timesheets, chasing the one person who submits late, entering commission adjustments, reviewing the register before approval, funding the account, submitting the remittance, filing the confirmation, and answering the two questions that always follow the deposit.
And that is a clean year. It assumes nothing went wrong.
What going wrong costs
The CRA penalty for a late remittance is tiered by lateness: 3% at one to three days, 5% at four to five days, 7% at six to seven days, and 10% once you pass seven days. For a business remitting $18,000 a month, a single remittance that slips past the one-week mark costs $1,800 considerably more than the entire year’s software bill.
Late T4 filing adds its own penalty: $10 per day to a $1,000 maximum for a business filing fifty slips or fewer.
These are not exotic scenarios. They happen when the person who runs payroll is on vacation, or ill, or simply busy in the week a deadline lands. In a small business, payroll is almost always a single point of failure with no backup.
What outsourced payroll costs in Calgary
Local accounting firms generally price small-business payroll monthly, based on headcount and pay frequency. For a business in the five-to-fifteen employee range, market rates in Calgary typically fall somewhere between $150 and $400 a month depending on complexity — commission structures, multiple provinces, benefit administration and year-end scope all move the number.
Annualised, that is roughly $1,800 to $4,800, usually with T4 preparation and CRA correspondence included rather than billed separately. Confirm that inclusion specifically; it is the most common source of an unexpected February invoice.
The break-even, stated plainly
On a straight cash comparison, outsourcing usually lands at or slightly below the fully loaded in-house cost once a business passes roughly five employees — earlier if payroll involves commissions, multiple provinces, or meaningful staff turnover.
But the cash comparison understates the case, because it prices the owner’s time at a bookkeeping rate. The hours a Calgary owner spends on payroll are not generic hours. They are the same hours that would otherwise go to quoting work, following up on receivables, or handling the client who is thinking about leaving. Priced at what those activities actually generate, four hours a fortnight is an expensive way to move money from one account to another.
There is also the single-point-of-failure problem, which no amount of software solves. A firm has coverage. One office manager does not.
Five questions worth asking before you sign
Not all payroll services are equivalent, and the differences show up at year end rather than in month one.
- Are T4 preparation and filing included in the monthly fee, or billed separately in February?
- Who handles CRA correspondence if a remittance is questioned — you, or them?
- How are commissions, bonuses and taxable benefits handled, and are they included in the base fee?
- What happens if they make an error that triggers a penalty? Get the answer in writing.
- Can they handle a second province if you expand? Adding B.C. staff means the Employer Health Tax and a different set of employment standards.
Calgary is well served here. There are national providers, cloud-first platforms, and local accounting firms including established Alberta and B.C. practices such as BMTS Corp payroll services in Calgary that combine payroll with bookkeeping and year-end work under one engagement. The combined approach tends to matter more than owners expect, because payroll data feeds the financial statements; when the two are handled by different parties, reconciliation becomes somebody’s problem, and that somebody is usually the owner.
The verdict
If you employ one or two people on straightforward salaries, in-house payroll is entirely reasonable. Keep it, and keep the remittance calendar visible.
Past five employees, or the moment commissions, a second province or real turnover enter the picture, the in-house number stops being competitive not because the software fails, but because the hours and the risk both climb while the subscription price stays flat. That is the point at which the honest calculation stops favouring doing it yourself.
Run the numbers on your own business before renewal season. Most owners are surprised by the processing-time line, and it is the one that decides the answer.
