First year self-employed? Why the CRA hasn't asked you for instalments — yet
No instalment reminder in your first year of self-employment isn't a free pass. It's a delay — and it sets up an April where you owe a full year of tax plus the start of next year's instalments at the same time.
Go out on your own and the first tax surprise isn't the paperwork — it's the silence. No employer deducting anything, no CRA letter asking for quarterly payments. It feels like a raise. It's a loan.
Why no reminder comes in year one
Instalment reminders are generated from your past returns. The CRA only asks for quarterly payments once your net tax owing — tax left over after any withholding — has crossed $3,000 ($1,800 in Quebec) on an assessed return. In your first self-employed year, your prior returns show salaried income with tax withheld. As far as the CRA's mail-merge is concerned, you're fine.
So your entire first-year tax bill — income tax plus both halves of CPP, since you now pay the employer share too — quietly accrues until you file the following April.
The April double-whammy
Here's the part almost nobody warns you about. Say you started freelancing in early 2026 and it goes well. In April 2027 you file, and owe the full year of 2026 tax in one lump. Your 2026 return now shows net tax owing over $3,000 — which flips the instalment switch. The CRA's August 2027 reminder will ask for instalments toward 2027, with the September and December amounts sized to catch up your entire 2027 liability by year-end.
Within a few months you can face: the 2026 lump sum, then two instalments that together approximate a full year of 2027 tax. That's close to two years of tax crossing your account inside eight months — the single most common cash crunch in early self-employment.
Year one's real job isn't paying the CRA. It's building the account balance that survives the first reminder.
The set-aside habit
The fix is boring and works: move a fixed percentage of every payment you receive into a separate account the day it lands.
How much? Your take-home pay at your expected profit level shows the combined federal-provincial tax bite at that income. Add self-employed CPP on top (both halves — roughly another 12% on your first ~$74k of net income until the contribution caps). For most freelancers earning $50k–$120k of profit, 25–30% of every invoice covers tax plus CPP with margin. The instalment calculator estimates net tax owing straight from your self-employment income, both halves of CPP included, so you can see the number you're setting aside for. High-income or HST-registered? Set the HST aside too — that money was never yours.
If the balance grows faster than the eventual bill — great. That's a refund you paid to yourself.
When the reminders start, don't panic
The first reminder is just the CRA switching you from annual to quarterly. Whether you must actually pay follows the two-part test, and the amounts on the reminder come with a zero-interest guarantee if you pay them as printed. With a year of set-asides banked, the instalments aren't a crisis — they're just your own account paying out on schedule.
The takeaway
The CRA's silence in year one is a deferral, not an exemption. Set aside 25–30% of every invoice from day one, and April of year two becomes a transfer between your own accounts instead of the month that nearly ends the business.
