CPP2 — formally the "second additional CPP contribution" — is a new tier of CPP contributions that began January 2024 as part of the 2016 federal-provincial CPP enhancement agreement. It applies at 4% on earnings between the existing first earnings ceiling (YMPE) and a new second earnings ceiling (YAMPE), set at roughly 14% above YMPE. Both employee and employer contribute. Self-employed pay both halves (8% combined).

What does CPP2 actually cost in 2024, 2025, and 2026?

In 2024, the first year, the band was narrow ($68,500-$73,200), capping employee CPP2 at $188. In 2025 the band widened to $71,300-$81,200, raising the employee max to $396. In 2026 the band is $74,600-$85,000, with employee max $416. Employers match each employee contribution; self-employed contribute both halves. The 2025 jump was the largest because the YAMPE multiplier was raised to 14% of YMPE.

Why did CPP2 contributions feel so much bigger in 2025 vs 2024?

Two reasons stack: the YMPE rose from $68,500 to $71,300 (the first ceiling indexed to wage growth), and the YAMPE multiplier on top of YMPE was bumped from 7% above YMPE to 14% above. The combined effect more than doubled the contribution band — from $4,700 wide in 2024 to $9,900 wide in 2025. From 2026 onward the YAMPE multiplier stays at 14%, so further increases reflect annual YMPE indexation only.

Do I get more CPP retirement benefit from CPP2?

Yes. CPP2 contributions translate into a larger CPP retirement pension because the benefit formula now includes both the original 25% replacement-rate base (capped at YMPE) and an enhanced second-tier benefit (33.33% replacement on the YMPE-YAMPE band). The enhancement phases in fully over 40+ years of contributions — anyone retiring before 2065 gets a partial benefit weighted by years of CPP2 contributions made.

Is CPP2 deductible / a tax credit?

For employees, the CPP2 contribution is a deduction (line 22215) — reduces taxable income at marginal rate. For self-employed, half is a deduction and half is a non-refundable credit. After-tax cost at a 30% marginal rate: the $416 employee CPP2 max in 2026 costs about $291 net of the deduction. Self-employed paying $832 nets to about $582 (rough — depends on whether the credit half is fully usable).

No. CPP / CPP2 contributions are mandatory for all employees and self-employed individuals between 18 and 70 (sole exception: those receiving CPP retirement benefits aged 65+ can elect out via Form CPT30). For owner-managers paying themselves dividends instead of salary, dividends do not generate CPP / CPP2 — but neither do they create RRSP room or CPP retirement entitlement. See Salary vs Dividend CCPC for the trade-off.

What's the all-in CPP cost for someone at $100k in 2026?

CPP1 employee: 5.95% × ($74,600 − $3,500) = $4,230. CPP2 employee: 4% × ($85,000 − $74,600) = $416. Total CPP employee 2026 = $4,646. For self-employed at $100k, both halves: roughly $9,292. Compare to 2019 (pre-enhancement, no CPP2): max was $2,749 — total CPP load on a high earner has nearly doubled in 7 years.

CPP2 Second-Tier Real Cost by Income (2024–2026)

Original analysis of what the new CPP2 second-tier additional contribution costs Canadian workers and the self-employed by income band during the 2024 → 2025 → 2026 phase-in. Includes after-tax effective cost and employer-side cost for owner-managers.

CPP2 phase-in 2024–2026

Year	YMPE (1st ceiling)	YAMPE (2nd ceiling)	CPP2 band width	Employee CPP2 max	Self-employed CPP2 max
2024	$68,500	$73,200	$4,700	$188	$376
2025	$71,300	$81,200	$9,900	$396	$792
2026	$74,600	$85,000	$10,400	$416	$832

CPP2 cost by income (2026)

Annual income	CPP2 (employee)	CPP2 (self-employed, both halves)	Employer-side cost
$60,000	$0	$0	$0
$75,000	$16	$32	$16
$80,000	$216	$432	$216
$85,000	$416	$832	$416
$100,000	$416	$832	$416
$150,000	$416	$832	$416

Below YMPE ($74,600 in 2026) there is no CPP2. Between YMPE and YAMPE the contribution scales linearly at 4% (employee) or 8% (self-employed). At and above YAMPE ($85,000) CPP2 caps. Owner-managers paying themselves salary from a CCPC pay both employee and employer contributions out of corporate cash, so $832 of total CPP2 cost per executive at YAMPE.

Why this matters

CPP2 is part of the largest expansion of CPP since the program's founding. The 2016 enhancement agreement raised the income-replacement target from 25% of YMPE to 33.33% of the (higher) YAMPE — a roughly 50% increase in lifetime CPP entitlement for high-earning workers. The cost is paid in over a 40-year phase-in (1st-tier enhancement: 2019-2023; 2nd-tier CPP2: 2024-onward). Anyone retiring before approximately 2065 gets a pro-rated benefit.

For owner-managers paying themselves dividends from a CCPC, this is a key consideration in the salary-vs-dividend choice: avoiding $832 of annual CPP2 cost looks like a win, but it also means foregoing 4% × 40-year CPP2 retirement benefit. The break-even depends heavily on actuarial assumptions and how much of the enhancement you'll see — see CPP/OAS Start Age Calculator and Salary vs Dividend CCPC.

For self-employed sole proprietors, both halves come directly out of net business income — at $85,000 of net business income the combined CPP1 + CPP2 self-employed contribution is approximately $9,292 in 2026, before income tax. This is the single biggest payroll-side cost change for Canadian self-employed in a generation.
