A deduction, not a credit, and that distinction pays
Child care costs in Canada are claimed as a deduction, which is more valuable than a credit for most families. A deduction comes straight off your income before tax is calculated, so it saves you tax at your full marginal rate. A $5,000 credit at 15 percent saves $750, but a $5,000 deduction for someone in a 30 percent bracket saves $1,500. That is why this tool asks for your marginal rate: the headline deductible amount is only half the story, and the real prize is the tax it removes.
The deduction is capped three separate ways, and the smallest cap wins. There is a per-child dollar limit, currently $8,000 for each child under 7 and $5,000 for each child aged 7 to 16, with a higher $11,000 limit for a child eligible for the disability tax credit. There is the actual amount you paid. And there is a limit of two-thirds of the lower-earning spouse’s income. The calculator takes the minimum of these three, then multiplies by your marginal rate to show the tax saving.
Why the lower earner usually has to claim
This is the rule that trips up most couples. As a general rule, the spouse with the lower net income must claim the child care deduction, regardless of who actually paid the daycare bills. It feels backwards, since the higher earner would save more tax, but the legislation in CRA Form T778 is firm. There are narrow exceptions: if the lower-income spouse was in school, hospitalized, in prison, or certified disabled for part of the year, the higher earner can claim for that period at a weekly rate. Outside those situations, plan around the lower earner’s bracket.
One child under 7, $15,000 of fees
Take the default: one child under 7, $15,000 paid in child care for the year, a lower-earning spouse making $50,000, and a 30 percent marginal rate. Three caps apply. The per-child limit for a child under 7 is $8,000. The amount paid is $15,000. Two-thirds of $50,000 is $33,333. The smallest is the $8,000 per-child limit, so $8,000 is deductible, saving $2,400 in tax at the 30 percent rate.
The two-thirds-of-income cap bites hardest when the lower earner makes very little. If that spouse earned only $9,000, the cap would fall to $6,000 and the deduction would shrink accordingly, even though you paid far more and the per-child limit is higher. With two children under 7 the combined per-child ceiling rises to $16,000, so families with multiple young kids and high fees more often hit the income cap than the dollar cap.
What qualifies, and what does not
Eligible expenses are broader than people assume. Licensed daycare, nannies, before and after-school care, day camps and even overnight camps and boarding school qualify, though overnight care has its own weekly dollar ceilings. The care must let you, or both spouses, earn income, go to school, or run a business. What does not qualify: payments to the child’s own parent, to a relative under 18, fees for education such as tuition itself, and medical or clothing costs. You need receipts with the caregiver’s social insurance number if they are an individual, because the CRA can ask for them.
This calculator is for working parents budgeting daycare against the tax relief it brings, couples figuring out which partner claims and how the income cap limits them, and anyone considering a nanny versus a daycare. A practical tip for couples: because the lower earner usually claims, families sometimes find that a modest second income is partly offset by losing access to a larger deduction, so it is worth modelling the after-tax math before assuming more hours always pay. Quebec families should also note the province runs its own refundable child care credit alongside the federal deduction, so the combined relief there is calculated differently.
Can I claim summer camp as child care?
Yes, day camps and day sports schools count as eligible child care, and overnight camps qualify too, subject to a separate weekly maximum per child rather than the annual figures. The camp must be care that allows you to work or study, not an educational program billed as tuition. Keep the camp’s receipt showing the amount and dates. This is one of the most overlooked eligible expenses, and families routinely leave it off the return simply because they think of camp as recreation rather than care.
What if the lower-income spouse had no income at all?
If the lower earner has no income, the two-thirds-of-income cap is zero, so ordinarily no deduction is available, which surprises stay-at-home households that still pay for care. The exception is when that spouse was in school, hospitalized, confined, or disabled during the year, in which case the higher-income spouse can claim a limited weekly amount for those weeks. Outside those circumstances, child care paid while one parent is home without qualifying reason is generally not deductible.
