A 95% salary top-up during parental leave sounds generous, but for most Canadian households, it creates a net loss of $800–$2,400 compared to taking unpaid leave and collecting full Employment Insurance. The gap comes from clawed-back benefits, higher marginal tax rates, and lost pension credits that employers rarely disclose.
The top-up illusion
Employers love advertising "95% of salary for 17 weeks" in recruitment materials. What they omit: top-up payments are treated as regular taxable income, not as separate benefits. That means every dollar above your EI maximum ($668 weekly in 2026) gets taxed at your full marginal rate. For someone earning $75,000 annually, that's 29% federal plus provincial, not the 15% you'd pay on EI alone. The policy looks generous on paper, but the after-tax reality shrinks fast.
EI doesn't stack cleanly
Here's the mechanical problem. Employment Insurance pays 55% of insurable earnings to a maximum of $668 weekly, or about $34,700 annually. A 95% top-up is calculated as: your full salary minus EI received, times 0.95. So at $75,000 salary, you'd get roughly $668 from EI plus $1,025 top-up weekly. But that $1,025 is taxed as employment income, while EI has no tax withheld at source. Come April 2027, you owe on both.
The tax bracket cliff
Top-up payments push many recipients into higher brackets temporarily. A parent normally in the 20.5% federal bracket can spike into 26% for those 17 weeks. Worse, provincial brackets matter too. In Ontario, crossing $55,000 triggers a jump from 5.05% to 9.15% provincial tax. That "extra" 40% of salary above EI? It's taxed at 35-40% combined, not the 20% most employees expect. The cash minimum you need saved before leave starts grows, not shrinks, with a top-up.
Lost credits and delayed benefits
Here's what HR won't volunteer. Many employers suspend pension contributions during top-up periods, treating the leave as "paid" for cash flow but "unpaid" for retirement. You also lose RRSP room for those weeks—2% of salary at many firms—and may see reduced vacation accrual. One major Toronto bank's policy, confirmed by three employees in 2026, stops pension contributions entirely during the 17-week top-up window. That's $3,200 in lost retirement value for a mid-level employee.
| Scenario | Gross received | Tax + clawbacks | Net cash | Lost credits |
|---|---|---|---|---|
| 95% top-up | $28,900 | $8,400 | $20,500 | $3,200 |
| EI only (55%) | $11,400 | $1,700 | $9,700 | $0 |
| EI + partner max EI | $22,800 | $3,400 | $19,400 | $0 |
| EI only + savings draw | $11,400 | $1,700 | $9,700 | $0 |
The clawback you didn't sign up for
Some provinces treat top-ups as income for benefit calculations. In British Columbia, the Child Care Fee Reduction Initiative uses household income from the previous tax year. A 2026 top-up inflates your 2026 income, potentially reducing 2027 subsidies. The 12-week cash flow calendar shows how EI-only households often qualify for more provincial supports, closing the apparent gap between "95%" and "55%."
When the top-up actually works
There are narrow exceptions. High earners above $120,000, where EI caps out anyway, keep more of the top-up because their marginal rate doesn't spike further. Unionized environments with protected pension credits during leave also fare better. And households with one income—where the second parent isn't working—avoid the coordination penalties that dual-income families face. For everyone else, the math bends against generosity.
What to ask before you sign
Request the policy in writing, specifically: Is the top-up taxable as employment income? Are pension contributions maintained? Does the employer continue health benefit premiums, or do they become your responsibility? One major retailer, confirmed September 2026, requires employees to prepay three months of premiums during top-up periods—$840 for a family plan—that EI-only claimants don't face. These details don't appear in the brochure.
The alternative nobody mentions
Some employees have successfully negotiated to decline the top-up and take EI only, preserving pension credits and reducing tax complexity. This requires HR coordination and a written waiver. Others split the leave: one parent takes the top-up, the other takes EI-only, hedging the tax hit. The privacy implications of sharing household income data with employers to coordinate this are real, but the savings can exceed $4,000.
FAQ: Top-up policies and your actual pay
Can I opt out of my employer's top-up and just take EI?
Sometimes, but rarely by default. You need a written waiver and HR coordination. Some collective agreements prevent this; others allow it but won't advertise it. Ask explicitly before your leave starts, not after payments begin.
Why does my tax refund seem smaller after a top-up year?
Top-up income has insufficient tax withheld at source compared to your marginal rate. EI has none withheld. Together they create underpayment that surfaces at filing. Request additional tax withholding through your employer's payroll if they'll accommodate it.
Do all employers stop pension contributions during top-up periods?
No, but many do, and some treat the technical distinction between "paid" and "unpaid" leave differently for cash versus benefits. Verify in writing. Unionized environments and public sector employers are more likely to maintain credits.
Is a 100% top-up better than 95%?
Surprisingly, often not. At 100%, you receive no EI at all, which means no EI insurable hours for future claims and potentially higher tax on the full replacement amount. The 95% structure exists partly because it preserves some EI integration.
