Instalments for income with no smooth months
Nothing is withheld from a course-of-care distribution, so the tax discipline is yours: a fixed percentage of every distribution moved to a separate account the day it lands, sized to your bracket plus both halves of CPP, which self-employed midwives pay in full. Once net tax owing passes $3,000, the CRA expects quarterly instalments, and its reminder notices are calculated from prior years. In a year when your income drops, a leave year, a reduced caseload, those notices overshoot badly; the current-year method lets you pay instalments on what you are actually earning, provided the estimate is honest.
The calendar has one trap worth naming twice: self-employed returns are due June 15, but the balance owing is due April 30. The later deadline is for paperwork, not for money.
Midwifery also hands you something most self-employed clients never get: predictable raises. Course-of-care rates step up with years of experience on a published scale, so you can see a higher-income year coming well in advance. That is the year to bump the set-aside percentage before the first distribution arrives at the new level, not after the April surprise confirms it.
Parental leave is a tax plan with a twelve-month fuse
Course-of-care fees follow the midwife who provides the care. When a locum takes your caseload, the fees go with it, while your overhead share usually keeps running under the practice agreement. So a leave has three funding sources to arrange, and the first one has a statutory clock: EI special benefits for the self-employed require you to register with the program and then wait twelve months before any claim. Registering after the positive test is registering too late.
| When | The move | Why then |
|---|---|---|
| Twelve or more months out | Register for EI special benefits; start a dedicated leave fund | Claims only open twelve months after registration |
| Six months out | Confirm the locum arrangement and your overhead share in writing | Fee income stops; the practice agreement decides what keeps costing you |
| During leave | Switch instalments to the current-year method; consider claiming no CCA | Payments should track a low-income year, and CCA is a choice, not an obligation |
| First year back | Rebuild the per-distribution set-aside; resume the CCA claims you banked | Fees return at your experience level, and so does the tax on them |
The leave year is also your lowest-bracket year in a decade, which makes it valuable. Capital cost allowance on your vehicle and Class 8 equipment is discretionary, so skipping it in a low year preserves the deduction for full-caseload years where it saves tax at a higher rate. That one timing decision often outweighs everything else on this page.
The incorporation question is arithmetic, not ambition
A Health Profession Corporation defers tax; it does not erase it. The first $500,000 of active income is taxed around 12.2% combined in Ontario against personal rates that can run four times that, but the gap only becomes money if earnings stay inside the corporation. A midwife who spends most of what she bills gains a T2 and a fee, not a saving. And because only CMO members can hold shares, the family income-splitting story that sells incorporation in other professions is simply unavailable here. We run the arithmetic both ways before anyone incorporates, and our Incorporation page for midwives covers what the College requires.
Smaller moves that fit a caseload practice
- Spousal RRSPs spread retirement income across two returns legitimately, and TOSI has nothing to say about them.
- Real wages for real work: paying a spouse a reasonable salary for clinic administration they genuinely perform is deductible; paying them for nothing is not, and the CRA knows the difference.
- Equipment timing: buy the new Doppler or the practice vehicle in a high-income year, where the first year of CCA is worth the most.
- RRSP versus corporation: for most members, filling RRSP and TFSA room beats retained earnings until both are consistently maxed.
Planning is a conversation that should not wait for April. Our Tax Planning & Advisory engagements are quoted in writing after a free 15-minute call, and for a solo midwife who mostly needs a CPA on call between decisions, CPA Quick Support at $99 a month is usually the right size.
