Midwife tax services: filing on top of a T4A from your own practice group

The T4A is the start of the return, not the whole of it

The amount on the T4A your practice group issues is your gross distributed income for the year, and it flows onto a T2125 as a self-employed midwife's business income unless you bill the group through a Midwifery Professional Corporation, in which case it becomes revenue on the corporation's T2 instead. What CRA never sees on that slip is your caseload mix across the year — a heavier on-call quarter, a stretch of mentoring a new registrant, or a locum period covering another midwife — so your own records, not the T4A, are what supports the return if anything is ever questioned.

Exempt status is settled; your deduction list still needs discipline

Midwifery is listed as an exempt basic health care service under the Excise Tax Act, so there is no HST question to resolve on your course-of-care income and no GST/HST return to file on it. That leaves income tax deductions as the place where the real work happens, and the list is specific to how a midwife actually practises:

• Vehicle costs for home visits, hospital call-outs at any hour, and travel between clinic sites, logged against actual kilometres rather than estimated after the fact.
• College and association dues — CMO registration and AOM membership — plus NRP, CPR, and other required recertifications.
• On-call communication, the phone or pager you carry specifically for births, prorated if it also serves personal use.
• Liability and malpractice contributions not already carried by the practice group.
• Home-office costs for charting, on-call administration, and continuing education, calculated on the same basis as any self-employed professional's workspace.

None of these deductions reduce the group's TPA funding — they reduce your personal taxable income against the T4A you were already issued. Keeping receipts and a mileage log current through the year, rather than reconstructing them the week the T1 is due, is what makes this list worth the paperwork instead of an afterthought.

If you also earn outside the funding model, split it at the source

A midwife who teaches a paid prenatal class, sells postpartum supplies, or does private consulting outside the Ministry funding model is generating ordinary taxable revenue that sits beside her exempt course-of-care income rather than inside it. Once that side income plus any other taxable activity clears the $30,000 small-supplier threshold, HST registration applies to the taxable slice only — the exempt midwifery income never counts toward that threshold and never gets HST charged against it. Practices that blend these into one deposit stream tend to discover the split only when a return is already overdue; we set the accounts up so it never has to be reconstructed. The same logic applies if the practice group itself sells anything beyond funded care — supplies, classes, or room rentals to another practitioner — since the group's own filing carries the identical exempt-versus-taxable line that yours does personally.

Instalments and CPP catch new registrants off guard

A midwife's first full year of course-of-care income rarely has tax withheld anywhere along the way, which means the balance owing at filing time can be larger than expected — and once net tax owing exceeds the CRA's threshold in two consecutive years, quarterly instalments become mandatory going forward, not optional. Self-employed midwives also pay both the employee and employer portions of CPP on their net business income, a cost that surprises anyone comparing their T4A total to what a T4 employee would have taken home. We model instalments and the CPP2 top-up as soon as a full year of distributions is on the books, so the first large payment is expected rather than discovered.

The professional corporation changes the form, not the exemption

Billing your course-of-care share through a Midwifery Professional Corporation moves your filing from a T1 with a T2125 to a corporate T2, opens the door to the small business deduction on active income retained in the corporation, and lets you time personal salary or dividends against your own cash needs rather than pulling everything out in the year it is earned. It does not change the exemption itself, and it does not change the funding agreement, which still sits with the practice group — the corporation only changes how your own share is taxed once it reaches you. We walk through that comparison on our midwife incorporation page before you commit to either structure.
