The first strong year in real estate feels like the finish line. For a lot of new agents, the tax bill says otherwise: the second good year is the one that costs the most.

It is not that the second year earns less. It is that three obligations come due together, none of them gives much warning, and each one is worked out from a year the agent has already spent.

The pattern is not fraud and it is not carelessness. It is timing, and it catches good agents. Outside Quebec, where pension and sales tax work differently, it runs like this.

 

Nothing comes off the cheque

 

An agent paid as an independent contractor receives their share of each commission in full. No income tax is withheld, and no Canada Pension Plan contributions are either.

The CPP piece surprises people. A self-employed person pays both the employee and the employer share: 11.9 per cent of net earnings between $3,500 and $74,600 in 2026. An agent who nets $60,000 this year owes $6,723.50 in CPP before a dollar of income tax.

In the first good year, all of that arrives as one balance due April 30. It hurts, but it arrives once, and nobody charges interest for not having paid it sooner.

 

The instalment trap

 

Year two is different. The Canada Revenue Agency requires quarterly instalments when your net tax owing is more than $3,000 this year and was also more than $3,000 in either of the two previous years.

A strong first year satisfies the second half of that test by itself. The CRA sends instalment reminders in February and August, based on your latest assessed return, and the due dates are March 15, June 15, Sept. 15 and Dec. 15. Once the breakout year has been assessed, the reminders start arriving.

Many new agents treat those reminders as a suggestion. Once you are required to pay instalments and have received a reminder showing an amount, the CRA charges instalment interest, compounded daily, on any payment that is missed, late or short.

Put dates on it. Say an agent’s breakout year is 2025. The balance for 2025 is due April 30, 2026. That August, if the 2025 return has been assessed, a reminder asks for instalments on Sept. 15 and Dec. 15. If the agent skips them and has another good year, then by April 30, 2027, they owe the rest of the 2026 balance plus instalment interest, and the first 2027 instalment was already due on March 15. A year of tax and the start of the next one fall due within about six weeks. That is the expensive year.

 

The GST/HST line many agents cross without noticing

 

The third obligation is GST/HST. Commissions are taxable, and an agent stops being a small supplier once taxable revenue passes $30,000, either in a single calendar quarter or over four consecutive quarters.

Cross it in a single quarter and registration takes effect no later than the day of the commission that took you over, which means that commission itself should have carried the tax. Cross it gradually and you stop being a small supplier at the end of the month after the quarter in which you passed $30,000. Either way, you then have 29 days to register.

An agent who notices a year late has not escaped the tax on the commissions since. It was still owed. It was never charged to the brokerage, so the agent has to remit it anyway and can ask the brokerage to pay it. If the brokerage will not, it comes out of the agent’s own pocket.

There is an upside. Once registered, you can claim input tax credits for the GST/HST you pay on business expenses, from marketing to your phone bill.

 

What brokers and team leads can do

 

Most of this is invisible from the agent’s side until it arrives. It is very visible from the brokerage, which sees every commission it pays.

That makes onboarding the right moment. Three habits prevent most of it.

First, a separate account for tax, funded from every cheque: the GST/HST portion goes in first, because that money was never the agent’s, then a fixed share for income tax and CPP, worked out once with an accountant and revisited each quarter.

Second, a running commission total checked against the $30,000 line every quarter, not at year-end. The brokerage already has most of this number.

Third, a standing rule that the first instalment reminder gets paid. It is the CRA saying, months ahead, what next April would otherwise cost.

This is worth 10 minutes with every new agent heading into a first good year. Many agents who struggle after their second good year could sell perfectly well. What catches them is the timing.
