Medical Expenses: Organize Receipts Before Filing
Gather receipts in the eligible person’s name and choose the most advantageous twelve-month period.
Published 2026-07-21
A family's medical expenses often end up in a drawer, then in a bag at the accountant's, and that method leaves money on the table every year. Preparation changes the result in three moves. Sorting by eligible person first: receipts can be claimed for oneself, the spouse and dependants, each receipt in the right person's name. The subtraction next: insurance reimbursements get deducted, only the unreimbursed portion counting, the insurer's statements reconciled with the receipts, and eligibility verified against the official list — physiotherapy on it, vitamins not, medical mileage following its own rules. The period choice last, the ignored lever: the claim can cover any twelve-month period ending in the year, and shifting the window to capture a major expense sometimes changes the result notably, the income-based threshold crossing more easily on a loaded period. This article organizes continuous filing and the optimal-window calculation.
Group the receipts under the right person
Medical expenses are claimed for yourself, your spouse and dependants, and receipts must carry the name of the person who received the care. Grouping them on a single spouse's return is generally advantageous, since only expenses above a threshold calculated on income qualify: concentrating the expenses with the lower-income spouse lowers that threshold and increases the credit. That calculation is done each year, incomes changing, and it justifies keeping all the household's receipts in one place.
Choose the twelve-month period
The rule that most often escapes people is the period one: expenses are claimed over any twelve-month period ending in the tax year, not necessarily the calendar year. That flexibility allows grouping into one period significant expenses that straddled two years, which can push the total above the threshold where two separate claims would both fall below it. The choice is made by trying several twelve-month windows against the receipts' actual dates, an exercise taking half an hour and sometimes worth several hundred dollars. Try several windows.
Subtract what was reimbursed
Only the unreimbursed portion qualifies: the share paid by group or individual insurance is subtracted, and the insurer's settlement statements establish the net amount. A thousand-dollar dental bill reimbursed at eighty percent leaves two hundred dollars claimable. Premiums paid by an employee to a private health insurance plan are themselves eligible expenses, often forgotten though they appear on the year-end statement. The method that works files the receipts as they arrive, with the corresponding insurance statement stapled to each.
Verify eligibility against the official list
The list of eligible expenses is broader than most people assume: it includes travel costs to obtain care unavailable nearby, certain devices, various professional services, and attendant care. It excludes, by contrast, expenses that seem medical, such as many over-the-counter products, certain supplements and part of the wellness services. Some expenses require a prescription or a written certification to qualify, a document to obtain at the time of service rather than a year later at filing time. Asking the practitioner for it at the counter takes ten seconds; obtaining it retroactively from a clinic that has since changed systems can take weeks, and sometimes never succeeds at all. Clinics rarely keep those records long.
Quebec scenario: compare before confirming
The kitchen drawer of a family in Roberval contains, in bulk, the complete medical year: the eldest's orthodontics, the youngest's glasses, the father's physiotherapy, prescriptions, mileage to appointments in Chicoutimi. Every spring, the drawer empties into a bag and the bag goes to the accountant, who extracts what he can. This year the mother decides to prepare rather than hope, and the preparation changes the result. The sorting first, by eligible person: receipts can be claimed for her, her spouse and the dependent children, each receipt in the right person's name — the orthodontics billed in the teenager's name attaching to the family file without difficulty. The subtraction next, the one that prevents bad surprises: group-insurance reimbursements get deducted, only the unreimbursed portion counting, and the insurer's statements are reconciled against the receipts one by one. The eligibility check follows, against the official list rather than the rumour mill: physiotherapy is there, over-the-counter vitamins are not, and medical mileage obeys its own distance and calculation rules. The choice of period last, the lever almost nobody pulls: the claim can cover any twelve-month period ending in the year, and shifting the window to capture January's orthodontic instalment adds $1,850 to the total. The threshold based on family income being crossed, the credit lands on both sides, federal and provincial. The drawer still exists, but a divider per person has disciplined it: next year, the preparation will take an hour.

Frequently asked questions
Which medical expenses can I claim, and for whom?
The eligible expenses on the official list, for you, your spouse and dependants — each receipt in the right person's name. Physiotherapy is there, over-the-counter vitamins are not, and medical mileage follows its own rules: the official list decides, not the rumour mill.
Why subtract insurance reimbursements?
Because only the unreimbursed portion counts: the insurer's statements get reconciled against the receipts one by one, and claiming an amount already reimbursed invites a reassessment. Sorting by person and reconciling do most of the preparation work.
How do I choose the twelve-month period?
Freely, as long as it ends in the tax year: it is the lever almost nobody pulls. Shifting the window to capture a major expense — orthodontics, surgery — sometimes changes the result notably, the income-based threshold being more easily crossed by a loaded period.
