Payroll Software for Alberta Accounting Firms
Remitter types, remittance schedules and slip season tracked per client.
Payroll software for Alberta accounting firms means tracking the work rather than keeping the books: Alberta clients charge 5% GST and no provincial sales tax, and every corporate file runs a T2 six months after its fiscal year-end with the balance due earlier. SpidNums puts those obligations on one colour-coded board, hosted in Canada.

How does payroll software work for firms in Alberta?
The CRA administers the GST. Alberta levies no provincial sales tax. Alberta is the only province with no provincial sales tax, so Alberta clients file GST returns only.
Source deductions are federal, so the CRA's remitter tiers apply the same way in Alberta as everywhere else. What varies is what sits on top: several provinces levy employer payroll taxes above an exemption threshold, and those are provincial filings with provincial deadlines. Confirm the current rate and threshold with the province before advising, and model the provincial levy as its own service so it carries its own date.
Managing payroll software across a client book in Alberta
Payroll compliance is a scheduling problem before it is a calculation problem: the CRA assigns each employer a remitter type, the type sets the deadline, and the type changes.
A four-person Calgary practice serving oilfield-services corporations tracks two returns per corporate client: the federal T2 and the Alberta AT1. Sales tax is the easy part — GST only, one cadence, no PST registration. The compliance weight sits in the doubled corporate filing and in year-ends that cluster around the fiscal calendars of the operators these clients contract to.
What is different about running a practice in Alberta?
Four things a firm working Alberta files should be able to state without looking them up. Each is verified against a primary source, linked at the foot of this page.
CPA Alberta is the provincial body; 137,182 of Alberta's 139,514 employer businesses were small businesses as of December 2024.
- No provincial sales tax — Alberta is the only province without a provincial sales tax. Alberta businesses charge 5% GST and file a single sales-tax return with the CRA — there is no PST, RST or QST registration to track.
- Lowest general corporate rate in Canada — Alberta's general corporate income tax rate is 8%, the lowest provincial general rate in Canada, and its small-business rate is 2% on the first $500,000 of active business income.
- A second corporate return: the AT1 — Alberta Tax and Revenue Administration administers the Alberta Corporate Tax Act. Corporations with a permanent establishment in Alberta must file an Alberta AT1 return in addition to the federal T2 — one of only two provinces (with Quebec) that require a separate corporate filing.
- Fourth-largest business base — Alberta had 139,514 employer businesses as of December 2024, of which 137,182 were small businesses.
Which CRA deadlines apply?
These rules are federal and apply in every province and territory. Where a due date falls on a weekend or public holiday, the CRA treats the next business day as on time — compute the shifted date each year rather than carrying the calendar forward.
| Filing | Applies to | Filing deadline | Payment | If it is late |
|---|---|---|---|---|
| Payroll source deduction remittances | All employers. Frequency is set by the average monthly withholding amount (AMWA) from two years prior. | Quarterly remitters (AMWA under $3,000 with a clean compliance record, and eligible new small employers) remit by the 15th of the month after each calendar quarter. Regular remitters (AMWA under $25,000) remit by the 15th of the month following the month deductions were made. Accelerated Threshold 1 remitters (AMWA $25,000 to $99,999.99) remit by the 25th for pay periods ending the 1st to 15th, and by the 10th of the following month for periods ending the 16th to month-end. Accelerated Threshold 2 remitters (AMWA $100,000 or more) remit within three working days after each of four weekly periods, through a Canadian financial institution. | Not applicable | 3% for amounts one to three days late, 5% for four to five days, 7% for six to seven days, and 10% where more than seven days late or not remitted. A second or subsequent failure in the same calendar year, made knowingly or through gross negligence, carries a 20% penalty. |
| T4, T4A and T5 information returns | Every employer (T4), payers of pensions, annuities and fees for services (T4A), and payers of investment income (T5). | File the slips and summary with the CRA and distribute copies to recipients by the last day of February following the calendar year. Where that date falls on a weekend or public holiday, the next business day applies — compute the shifted date rather than assuming it. | Not applicable | A graduated late-filing penalty based on the number of slips and days late: a minimum of $100 and a maximum of $7,500, on a per-day scale that rises by tier. It is not a flat per-slip amount. |
How SpidNums handles it
SpidNums models the firm as clients, services and work. Assigning a typed service to an Alberta client is what generates the recurring projects, the stages and the reminders — the cadence is recorded once rather than remembered each period.
Every open obligation is then ranked by how close its due date sits and coloured accordingly, so the morning question — what is late, what is close, what is fine — is answered by looking.
- Remitter type modelled as the client's payroll service cadence
- Recurring remittance projects generated on the right schedule
- Slip-season projects opening in January for the February deadline
- Assignment per payroll clerk with live workload
- Reminders that fire before, not after, the remittance date
- One-field cadence change when the CRA reassigns a client
Where this goes wrong
Payroll failures are almost always calendar failures rather than calculation failures — the number was right and the date was wrong.
- The CRA reassigns a client's remitter type and the firm keeps remitting on the old schedule.
- A remittance lands three days late — the difference between a 3% and a 10% penalty.
- Slip season starts in February instead of January, so December payroll data is chased against a deadline instead of ahead of it.
- A seasonal employer's payroll service stays active out of season, or worse, stays inactive when the season starts.
What SpidNums does not do
SpidNums does not calculate payroll or file remittances. It tracks which client owes what and when, so the work reaches your payroll system on time.
If your firm already runs a tracking system it trusts, the honest answer is that you do not need this one. The pages on this site are written to help you decide, not to pretend every firm has the same problem.

Frequently asked questions
Does Alberta have a provincial sales tax?
Alberta charges the 5% federal GST and levies no provincial sales tax. The CRA administers the GST. Alberta levies no provincial sales tax. Alberta is the only province with no provincial sales tax, so Alberta clients file GST returns only.
What corporate tax rates apply in Alberta?
Alberta's provincial small-business rate is 2% on the first $500,000 of active business income, and its general provincial rate is 8%. Those sit on top of the federal rates — 9% federally on the first $500,000 and 15% federally on general income.
What happens when the CRA changes a client's remitter type?
The remitter type is modelled as the client's payroll service cadence, so changing it is a one-field edit. Next period's remittance projects and reminders are generated from the corrected rule rather than from a list someone wrote down last year.
Is client data stored in Canada?
Yes. SpidNums hosts client data in Canada, in the ca-central-1 region, with row-level tenant isolation, an append-only audit log and staff roles that support confidential-client gating.
Does SpidNums run payroll or file the remittance?
No. SpidNums does not calculate payroll and does not file remittances or slips. It models each client's remitter type as a service cadence, generates the work on the right schedule and assigns it — the calculation and the filing happen in your payroll system.
