Mortgage agent taxes in Alberta: what to set aside and when to pay
No tax comes off your commissions, so April can hurt. Here's how Alberta mortgage agents set money aside, handle instalments and lower the bill legitimately.
- Your commissions arrive with no tax taken off. Income tax and both halves of CPP are on you.
- Move a set percentage of every commission into a separate tax account the day it lands.
- Once you owe more than $3,000 in net tax, CRA will expect quarterly instalments.
- File by June 15, but pay by April 30.
The first year as a mortgage agent is often the best and worst year for taxes at the same time. Deals fund, commissions arrive in full, and nothing is withheld. Then the return is filed and the bill arrives. This guide covers mortgage agent taxes in Alberta in plain English: what you owe, how much to put aside, when CRA wants instalments, and the deductions that lower the number.
1What a self-employed mortgage agent owes
Most Alberta mortgage agents are licensed through a brokerage but work as independent contractors. Your commissions are business income, reported on form T2125 with your personal return. On your net income (commissions minus expenses) you'll owe:
- Federal and Alberta income tax, at the same rates as everyone else on the same income.
- Both halves of CPP. An employee pays half and their employer pays half. Self-employed, you pay both. This surprises a lot of new agents.
What you generally won't owe is GST on your commissions, since arranging mortgages is an exempt financial service. That's covered in our mortgage broker bookkeeping guide.
2How much to set aside from each commission
There's no single right percentage, because it depends on your income, expenses, RRSP contributions and family situation. As a starting point, many self-employed people put somewhere between a quarter and a third of each commission into a separate savings account. Once you have a year's return, your accountant can give you a sharper number.
Here's what that looks like on a hypothetical month, using 30% as an example:
| Deal | Commission | Set aside (30%) | Yours to use |
|---|---|---|---|
| Purchase in Terwillegar | $3,200 | $960 | $2,240 |
| Refinance in Spruce Grove | $2,100 | $630 | $1,470 |
| Renewal switch in Leduc | $1,400 | $420 | $980 |
| Month total | $6,700 | $2,010 | $4,690 |
Notice the set-aside is on the full commission, not on profit. That builds in a cushion: your expenses will lower the actual bill, and whatever is left over after you file is a pleasant surprise rather than a scramble. If your set-aside account ends the year well over what you owed, your accountant can help you lower the percentage for next year.
Set up an automatic transfer, or do it the day each commission lands. If the money isn't in your everyday account, you won't spend it. And if a clawback comes later, adjust your set-aside the other way.
3Mortgage agent tax instalments
Once your tax bill gets big enough, CRA stops waiting until April. You have to pay quarterly instalments if your net tax owing is more than $3,000 in the current year and in either of the two previous years. Net tax owing is roughly what's left after anything withheld, so self-employed people cross it quickly.
CRA sends instalment reminders with suggested amounts based on past returns. Pay those and you won't be charged instalment interest, even if your final bill ends up higher. Tap through each date as you pay it:
Tap a date once that instalment is paid.
If your income drops, say during a slow rate environment, you can choose to base instalments on your own estimate of this year's tax instead. Just know that if you underestimate, CRA can charge instalment interest on the shortfall, so be realistic.
The instalments come out of the money you've been setting aside, which is the whole point of setting it aside. Our quarterly instalments guide explains the three ways to calculate them.
4Filing and payment deadlines
Self-employed people and their spouses have until June 15 to file their return. But any balance owing is due April 30, and interest starts on May 1. Plenty of agents file in June and get a bill with six weeks of interest on it. If you're filing late, estimate what you owe and pay it by April 30 anyway.
5Deductions that lower your mortgage agent taxes
Every legitimate expense reduces both your income tax and your CPP. The ones mortgage agents most often under-claim:
Because your income is generally GST-exempt, claim expenses at their full cost including GST. Keep the receipt or invoice and proof of payment for each one, since CRA can ask for support for up to six years.
RRSP contributions don't appear on the T2125, but they reduce your taxable income too, and are worth discussing with your accountant in a strong year. So is whether incorporating ever makes sense for you.
6Common tax mistakes for new mortgage agents
- Treating the first year as the normal year. Your first year usually has no instalments, because CRA has no history to base them on. The second year can bring last year's balance plus instalments for the current year, close together. Plan for both.
- Setting money aside "when things slow down". Things rarely slow down on schedule. A percentage of every deposit works; good intentions don't.
- Forgetting clawbacks. A clawback reduces your income, so it reduces your tax too. Record it, or you'll pay tax on money you gave back.
- Mixing business and personal accounts. It makes expenses harder to prove and your set-aside harder to track.
- Filing late and paying late. Missing April 30 means interest, and filing after June 15 adds a late-filing penalty if you owe.
None of this requires you to become a tax expert. It needs clean monthly books, a savings habit and a calendar with four instalment dates on it.
