For the first time since the current structure was set in 2003, the combined employer-employee base Canada Pension Plan contribution rate is coming down. Starting January 1, 2027, it drops from 9.9% to 9.5% — a change that is now law, not a proposal, and one that applies identically to every employer and self-employed person outside Quebec, whether the business is in Calgary, Vancouver, or Toronto. The change is real, but it is also narrower than the headline number suggests, and payroll teams should understand exactly what moves and what stays exactly where it is.
The change is enacted, not proposed
The rate cut was first announced in the federal government's Spring Economic Update, tabled in Parliament on April 28, 2026. It became law when Bill C-30, the Spring Economic Update 2026 Implementation Act, received Royal Assent on June 19, 2026. Division 5 of Part 3 of the bill amends the Canada Pension Plan Act to reduce the base contribution rate from 9.9% to 9.5% (a combined employer-and-employee rate), effective for 2027 and later years. This is the standard the newsroom rule applies to: a bill at first reading is a proposal, but Bill C-30 has passed all three readings in the House, cleared the Senate, and received Royal Assent — it is now enacted federal legislation.

CPP is a federal-provincial program, so a substantive rate change also needs the agreement of two-thirds of the provinces representing two-thirds of the population. That sign-off came out of the 2025–2027 triennial review of the plan, where federal, provincial, and territorial finance ministers agreed to the reduction after the Chief Actuary's report confirmed the plan could sustain a lower rate.
Why the rate is coming down: the actuarial math, not a policy trade-off
This is not a tax cut layered on top of the CPP for political reasons — it is a response to an actuarial finding. The Office of the Chief Actuary's 32nd Actuarial Report on the Canada Pension Plan, tabled with Parliament on December 8, 2025, found that the base CPP only needs a minimum contribution rate of roughly 9.19% to remain sustainable over a 75-year projection horizon. The legislated rate of 9.9% had been running well above that minimum since 2003, building a larger cushion than the plan actuarially requires. The reduction to 9.5% still leaves a margin above the 9.19% sustainability threshold, so the fund's long-term asset-to-expenditure ratio keeps growing under the new rate — it does not put the plan on a weaker footing, according to the Chief Actuary's own numbers.
What actually changes on the pay stub
This is the part payroll administrators need to get precisely right, because "CPP" on a 2026 pay stub is really two layers stacked together, and the 2027 cut only touches one of them.
- The base rate — the original CPP contribution structure that has stood at 4.95% for the employee and 4.95% for the employer (9.9% combined) since 2003 — drops to 4.75% employee / 4.75% employer (9.5% combined) effective January 1, 2027. This is the layer Bill C-30 amends.
- The CPP enhancement — the additional layer phased in since 2019, currently 1.0% each for employer and employee on earnings up to the Year's Maximum Pensionable Earnings (YMPE) — is not affected by this change. It continues unchanged.
- CPP2, the second additional tier introduced in 2024 on earnings between the YMPE and the Year's Additional Maximum Pensionable Earnings (YAMPE), currently 4% each for employer and employee, is also not affected.
Put together: for 2026, the combined employee rate on earnings up to the YMPE is 5.95% (4.95% base + 1.0% enhancement), plus 4% CPP2 on earnings between the YMPE and YAMPE. From January 1, 2027, that first-tier employee rate becomes 5.75% (4.75% base + 1.0% enhancement) — a 0.20-percentage-point reduction, not a 0.4-point one, because only the base layer moves. The same logic applies on the employer side.

What it means in dollars, and the caveat on that figure
For an employee earning around $70,000, commentary following the announcement has put the annual savings at roughly $133 for the employee's own contribution, with a matching reduction for the employer. Treat that figure as an approximation rather than a precise 2027 number: the exact dollar saving for any given employee or employer depends on the 2027 YMPE and Year's Basic Exemption, which the CRA has not yet announced (the YMPE is normally released in November for the following year, after that year's average wage data is finalized). What is fixed by statute already is the rate itself — 9.5% combined base rate, 4.75% each side — regardless of what the 2027 earnings ceiling turns out to be.
What businesses and payroll providers should do between now and January 2027
- Do not change anything in 2026 payroll systems now. The 4.95%/4.95% base rate stays in effect for all of 2026; the 4.75%/4.75% base rate only takes effect for pay periods on or after January 1, 2027.
- Flag it for your 2027 payroll setup. Most payroll software (and the CRA's own payroll deductions tables) will be updated to reflect the new base rate before the CRA publishes its 2027 maximum pensionable earnings and contribution rate announcement, typically in November 2026. Confirm your provider's release notes reference the 9.5% base rate specifically, not just an unchanged combined figure.
- Update payroll cost forecasts and budgets for 2027, particularly for businesses budgeting statutory payroll costs alongside other 2027 changes (minimum wage indexing, WCB/WorkSafeBC/WSIB premiums, and provincial payroll tax thresholds), since the CPP reduction is a small but real offset to rising costs elsewhere.
- Don't confuse this with Quebec's QPP. The Quebec Pension Plan is a separate, provincially administered plan and is not directly bound by this federal CPP Act amendment; Quebec sets its own QPP rates through its own process. This matters only if a business has Quebec-based employees — for employers operating solely in Alberta, BC, or Ontario, CPP applies to all employees.
Key takeaways
- The CPP base contribution rate drops from 9.9% to 9.5% (combined) starting January 1, 2027 — enacted via Bill C-30, which received Royal Assent June 19, 2026, not merely proposed.
- The employee and employer base rate each fall from 4.95% to 4.75%.
- The CPP enhancement (1.0% each) and CPP2 (4% each) are unchanged — the effective first-tier employee rate moves from 5.95% to 5.75% in 2027, a 0.20-point reduction, not 0.40.
- The change follows the Chief Actuary's 32nd Actuarial Report (tabled December 8, 2025), which found the plan sustainable at a lower rate, and unanimous federal-provincial-territorial finance minister agreement.
- No 2026 payroll action is needed now — the new rate applies to pay periods starting in 2027, and the exact dollar impact depends on the 2027 YMPE, expected around November 2026.
This is a federal change that applies the same way everywhere outside Quebec, so it affects payroll budgets for businesses in Alberta, BC, and Ontario identically. RN Canada works with owner-managed businesses across all three provinces to keep payroll cost forecasting and statutory remittance planning current as changes like this one take effect.
