Canada Statutory social-insurance contributions

What this value means

What a payroll engine gets wrong in Canada, in rough order of how often it is got wrong: 1. TREATING PROVINCE OF RESIDENCE AS THE DRIVER. CPP-vs-QPP and federal-vs-Quebec EI both turn on PROVINCE OF EMPLOYMENT (CPP s. 4(4)), never on where the employee lives. NT/NU payroll tax turns on where the work is physically performed. Income tax withholding, by contrast, follows province of employment too — but the NT/NU payroll tax explicitly does not follow residence and is not creditable against territorial income tax. 2. MODELLING CPP AS A SINGLE CAPPED BAND. There are two bands with two rates, two ceilings and two T4 boxes: 5.95% between CAD 3,500 and CAD 74,600, then 4.00% between CAD 74,600 and CAD 85,000. Missing CPP2 under-withholds up to CAD 416 per employee per side. 3. GETTING THE EI EMPLOYER SHARE WRONG. It is 1.4 x the employee premium (EIA s. 68), not a match — 2.282% federally, 1.82% in Quebec. And the 1.4 is not universal: an ESDC-approved short-term disability plan gives a reduced multiplier (EIA s. 69(1)) applying only to covered employees, which forces a second payroll program account. 4. REUSING ONE CEILING. Canada has four different 2026 ceilings running simultaneously and none of them match: CAD 68,900 (EI), CAD 74,600 (CPP/QPP), CAD 85,000 (CPP2/QPP2), CAD 103,000 (QPIP and the Quebec labour standards contribution). The CPP basic exemption of CAD 3,500 is a floor, and it must be pro-rated per pay period (CAD 291.66 monthly, CAD 134.61 bi-weekly) — applying the full CAD 3,500 to a single period is a classic error. EI has no floor at all and starts at the first dollar. 5. CONFUSING CEILINGS WITH THRESHOLDS. Quebec's CAD 7.8 million HSF figure is a rate-reduction eligibility threshold: above it the full 4.26% applies to the WHOLE payroll — it caps nothing. Quebec's CAD 2 million WSDRF figure is an applicability threshold for a training obligation. Ontario's CAD 1 million EHT exemption is clawed back to zero above CAD 5 million associated payroll. British Columbia's CAD 1.5 million figure switches the calculation from a marginal 5.85% to a flat 1.95% on the entire payroll. None of these are contribution ceilings. 6. THE STATUTE DOES NOT STATE THE OPERATIVE NUMBER. Employment Insurance Act s. 4(1) still reads "$39,000" on the face of the consolidated Act; that figure has been superseded every year since 1997 by the s. 4(2) average-weekly-earnings formula, and the operative 2026 MIE of CAD 68,900 exists only because the Canada Employment Insurance Commission set it in September 2025 and published it under s. 66.5. Likewise the CPP Act contains no dollar figure for the YMPE or YAMPE — ss. 18 and 18.1 give formulas and CRA publishes the results. Anyone reading the consolidated statute alone will produce wrong numbers. Both statute and authority figure are reported here; the CRA/Commission-published figure is OPERATIVE. 7. DEDUCTIBILITY IS SPLIT WITHIN A SINGLE CONTRIBUTION. The base 4.95/5.95 of a CPP contribution (5.30/6.30 for QPP) gives only a 15% non-refundable tax credit under ITA s. 118.7 and is NOT deductible; the first additional 1.00% share and the whole of CPP2/QPP2 ARE deductible from income under ITA s. 60(e.1) and are subtracted from gross before income tax is computed in the CRA withholding formula. EI and QPIP employee premiums are credit-only, never deductible. Treating the whole CPP contribution as deductible, or none of it, both produce wrong net pay. 8. STALE QUEBEC RATES. Two Quebec rates moved for 2026 after long freezes and are the most likely stale values in any engine: QPP fell from 6.40% to 6.30% each side, and QPIP fell from 0.494%/0.692% to 0.430%/0.602% after six years unchanged. 9. AGE AND ELECTION RULES DIFFER BETWEEN CPP AND QPP. CPP: ages 18–69, with a Form CPT30 opt-out available at 65–69. QPP: ages 18 up to and including the year the employee turns 72, with an opt-out at 65–72 for those already drawing a QPP/CPP retirement pension. EI has no age limit at either end. No CPP/QPP for an employee deemed disabled under either plan. 10. PER-EMPLOYER, NOT PER-EMPLOYEE, MAXIMUMS. Both the CPP and EI annual maximums apply separately to each employer (different business numbers). An employee with two jobs legitimately over-contributes across the year and recovers it on the personal return; the payroll engine must not aggregate across employers. 11. EMPLOYER-ONLY BRANCHES ARE INVISIBLE ON THE PAYSLIP BUT REAL COST: workers' compensation everywhere, plus in Quebec the Health Services Fund, the 0.06% labour standards contribution, the CNESST premium and possibly the 1% WSDRF levy, plus employer health taxes in ON/BC/MB/NL. Several of these (labour standards, WSDRF) are paid annually with the RL-1 summary in February rather than on the pay run, so they never surface in periodic remittance logic. SCOPE / EXCLUSIONS: nationality and immigration status are irrelevant to CPP/QPP/EI liability — coverage follows pensionable or insurable employment in Canada, not citizenship. Tax-exempt employment income of a First Nations (status Indian) employee is not pensionable. Non-arm's-length employment and employees controlling more than 40% of voting shares are excluded from EI (EIA s. 5(2)–(3)) while remaining subject to CPP. Self-employed persons and voluntary self-employed EI participation are out of scope. There is no mandatory private/occupational pension layer in Canada — registered pension plans and group RRSPs are contractual, not statutory, and are excluded here. SUB-NATIONAL VARIATION: QUEBEC (CA-QC) IS A COMPLETELY DIFFERENT PAYROLL REGIME, NOT A VARIANT. An employee whose PROVINCE OF EMPLOYMENT is Quebec pays QPP instead of CPP (6.30% each side, not 5.95%), a reduced EI rate (1.30% employee / 1.82% employer instead of 1.63% / 2.282%), and QPIP, which has no equivalent anywhere else in Canada (0.430% employee / 0.602% employer up to CAD 103,000). The employer additionally pays the Health Services Fund (1.25%–4.26%), the 0.06% labour standards contribution, the CNESST occupational health and safety premium, and possibly the 1% WSDRF training levy. Quebec source deductions are remitted to Revenu Québec, not the CRA, and reported on an RL-1 alongside the federal T4. Critically, the trigger is province of employment, not residence: an Ontario resident commuting to a Gatineau establishment is on QPP/QPIP, and an employee transferred mid-year between Quebec and another province needs both regimes pro-rated in the same tax year. NORTHWEST TERRITORIES (CA-NT) AND NUNAVUT (CA-NU): a 2% payroll tax levied on the EMPLOYEE and withheld by the employer, on top of CPP and EI. No other jurisdiction has an employee-side payroll levy. EMPLOYER HEALTH TAXES apply in four provinces only, each on its own scale: Ontario (CA-ON) 0.98%–1.95% with a CAD 1,000,000 exemption clawed back to nil above CAD 5,000,000 associated payroll; British Columbia (CA-BC) exempt to CAD 1,000,000, then 5.85% of the excess to CAD 1,500,000, then 1.95% of total remuneration; Manitoba (CA-MB) Health and Post Secondary Education Tax Levy; Newfoundland and Labrador (CA-NL) HAPSET. Alberta (CA-AB), Saskatchewan (CA-SK), Nova Scotia (CA-NS), New Brunswick (CA-NB), Prince Edward Island (CA-PE) and Yukon (CA-YT) have none. WORKERS' COMPENSATION differs in all 13 jurisdictions — separate boards, separate industry rate schedules, separate maximum assessable earnings. No national rate exists. CPP, CPP2 and EI rates and ceilings themselves are uniform across all 12 non-Quebec jurisdictions. WHAT WE DO NOT PUT A NUMBER ON: Deliberately returned with null rates rather than a guessed number: - QUEBEC HEALTH SERVICES FUND: no single rate exists. It is a sliding formula keyed to the employer's total payroll AND its sector. The full 2026 schedule is reproduced verbatim in the scheme notes so a caller can compute it, but rate_employer is null because no scalar is correct. - CNESST OCCUPATIONAL HEALTH AND SAFETY PREMIUM (Quebec): unit-rated by activity classification and then personalised by the employer's own claims experience. No national or even provincial scalar. Additionally, I could NOT READ the CNESST 2026 Schedule of Rates or the 2026 maximum insurable salary — cnesst.gouv.qc.ca serves a Cloudflare bot challenge to automated clients — so neither a rate nor a ceiling is asserted. The widely quoted "CAD 1.54 per CAD 100" 2026 average comes from commercial sources only and is not asserted as verified. - QUEBEC WSDRF TRAINING LEVY: not a rate at all. It is a 1%-of-payroll training obligation payable only to the extent of a shortfall in eligible training spend, so a compliant employer pays zero. Returning 1% would be wrong. - WORKERS' COMPENSATION (all 13 jurisdictions): 13 separate boards, each with its own industry rate schedule and its own maximum assessable earnings. No national rate and no national ceiling. - PROVINCIAL EMPLOYER HEALTH TAXES: four different provincial scales. Ontario and BC figures are given in the notes from the provinces' own pages; Manitoba and Newfoundland rates were NOT independently verified against their administering authorities in this pass and no numbers for them are asserted. - NUNAVUT PAYROLL TAX: the 2% rate and the employee-incidence are stated on the basis of the Northwest Territories Finance page (which is explicit that the NWT tax is levied on employees) plus the fact that Nunavut carried the NWT Payroll Tax Act, 1993 over at division. I could not open a Government of Nunavut page that states the rate and the incidence in its own words. The NT figures are primary; the NU figures inherit from the NT statute and should be re-verified before being sold as Nunavut-specific. - NWT CAD 5,000 DE-MINIMIS: reported by payroll vendors but absent from the GNWT Finance pages I read. Flagged, not asserted. - No income-tax rates, brackets or personal credits are included — out of scope, and Canada has separate federal and provincial/territorial schedules plus a distinct Quebec system. ALREADY LEGISLATED, NOT YET IN FORCE: No further legislated rate changes are pending for CPP or QPP. The CPP enhancement completed its phase-in in 2025: the base rate is fixed at 4.95%, the first additional rate at 1.00%, the second additional rate at 4.00%, and from 2025 onward the YAMPE is permanently set at 114% of the YMPE. Quebec's QPP reduction from 12.80% to 12.60% combined took effect 1 January 2026 and is the current operative rate, not a scheduled future change. What WILL change, on a predictable calendar, is every ceiling and the EI and QPIP rates: - CRA announces the 2027 YMPE and YAMPE in early NOVEMBER 2026. Re-verify the CPP and CPP2 ceilings after that date. - The Canada Employment Insurance Commission sets the 2027 EI premium rate and Maximum Insurable Earnings, and the Quebec reduction, by 14 SEPTEMBER 2026 (statutory deadline), published in the Canada Gazette under EIA s. 66.5. Re-verify EI and Quebec EI after that date. The 2026 rate of 1.63% was the third consecutive annual decrease. - Revenu Québec publishes 2027 QPP, QPIP, HSF and labour standards parameters in its "Employers: Principal Changes for 2027" page around late November 2026, based on measures announced before roughly 25 November 2026. - The QPIP employee/employer rates dropped for 2026 after six frozen years and are re-set annually by regulation; treat them as volatile. Open item with a live end-date: Quebec's TEMPORARY EXEMPTION FROM HEALTH SERVICES FUND CONTRIBUTIONS for the agriculture, forestry and fishing sectors was introduced in the 25 November 2025 economic and financial update and BROADENED on 28 January 2026. Its scope and expiry were not read in this pass and need separate verification before any HSF figure is served for those sectors. RECOMMENDED RE-VERIFY DEADLINE: 20 September 2026 for EI, and 15 November 2026 for CPP/CPP2 ceilings; full re-verification of the Quebec set on 1 December 2026. SOURCING CAVEATS: VERIFIED BY ACTUALLY FETCHING AND READING (all read in a real browser; canada.ca, revenuquebec.ca and cnesst.gouv.qc.ca all return HTTP 403 or a bot challenge to plain automated fetchers, so a headless scraper will fail on every one of these — build the ingestion accordingly): Primary — CRA (Canada Revenue Agency) own rate pages: 1. https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/payroll/payroll-deductions-contributions/canada-pension-plan-cpp/cpp-contribution-rates-maximums-exemptions.html — 2026 YMPE CAD 74,600, basic exemption CAD 3,500, maximum contributory earnings CAD 71,100, rate 5.95%, maximum CAD 4,230.45 each; per-pay-period exemption table; statutory cross-references. 2. https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/payroll/calculating-deductions/making-deductions/second-additional-cpp-contribution-rates-maximums.html — 2026 YAMPE CAD 85,000, CPP2 4%, maximum CAD 416 each. 3. https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/payroll/payroll-deductions-contributions/employment-insurance-ei/ei-premium-rates-maximums.html — 2026 MIE CAD 68,900; federal 1.63% / CAD 1,123.07 / CAD 1,572.30; Quebec 1.30% / CAD 895.70 / CAD 1,253.98. Both federal and Quebec tables are on this one page. 4. https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/payroll/payroll-deductions-contributions/canada-pension-plan-cpp.html — CPP age rules 18–69, CPT30 election, disability and First Nations exclusions, province-of-employment rule, per-employer maximums. 5. https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/payroll/payroll-deductions-contributions/employment-insurance-ei.html — EI from first dollar, no age limit, 1.4x employer, EI Premium Reduction Program, Quebec rule. Primary — Revenu Québec own rate pages: 6. .../calculating-source-deductions-and-contributions/qpp-contributions/maximum-pensionable-earnings-and-contribution-rate/ — 2026 MPE CAD 74,600, exemption CAD 3,500, rate 6.30% each, maximum CAD 4,479.30 each; AMPE CAD 85,000, second additional 4%, maximum CAD 416. 7. .../qpp-contributions/qpp-contributions-what-you-need-to-know/ — combined 12.60% / 6.30% each; age 18 to under 73; 65–72 opt-out; contributions stop at the AMPE. 8. .../qpip-premiums/maximum-insurable-earnings-and-premium-rate/ — 2026 MIE CAD 103,000, employee 0.430%, employer 0.602%, maxima CAD 442.90 / CAD 620.06. 9. .../employee-premium-under-the-quebec-parental-insurance-plan/ — independently restates the same 2026 QPIP figures and the 2025 comparatives (double-confirmed). 10. .../employer-contribution-to-the-health-services-fund/total-payroll-threshold-and-health-services-fund-contribution-rate/ — full 2026 HSF rate schedule and the CAD 7.8 million threshold. 11. .../contribution-related-to-labour-standards/ — 0.06%, 2026 maximum subject remuneration CAD 103,000, exclusion list. 12. .../contribution-to-the-workforce-skills-development-and-recognition-fund/ — CAD 2 million threshold, 1% obligation, shortfall mechanic. Primary — statute text (laws-lois.justice.gc.ca): 13. ITA s. 118.7 — confirms EI, base CPP/QPP and QPIP employee premiums give a CREDIT, and expressly names the "Act respecting parental insurance". 14. ITA s. 60(e) and 60(e.1) — confirms the ENHANCED employee contributions under CPP ss. 8(1.1)/(1.2) are DEDUCTIBLE. 15. EIA s. 4 — confirms the consolidated Act still states "$39,000" with the indexation formula in ss. (2)–(4). This is the Canadian consolidated-text trap. 16. EIA s. 68 — confirms verbatim "a premium equal to 1.4 times the employees' premiums". 17. EIA s. 69 — confirms 69(1) wage-loss-plan reduction (5/12 return to employees) and 69(2) as the legal basis for the reduced Quebec rate. Primary — territorial/provincial: 18. https://www.fin.gov.nt.ca/en/services/licences-taxes-et-droits/payroll-tax-employees — NWT payroll tax is 2%, levied on the EMPLOYEE, employer withholds, applies regardless of residence or age, exemption list, not on the T4, not creditable. 19. https://www.ontario.ca/document/employer-health-tax-eht — Ontario EHT CAD 1,000,000 exemption, CAD 5,000,000 clawback, 0.98%–1.95% graduated scale, Employer Health Tax Act. 20. https://www2.gov.bc.ca/gov/content/taxes/employer-health-tax/employer-health-tax-overview — BC EHT CAD 1,000,000 exemption, 5.85% marginal band, 1.95% flat above CAD 1,500,000. COULD NOT READ (and therefore not asserted): - CNESST 2026 Schedule of Rates and 2026 maximum insurable salary — Cloudflare bot challenge on cnesst.gouv.qc.ca. - A Government of Nunavut page stating the NU payroll tax rate and incidence in its own words. - The specific dollar figures inside CPP ss. 19–20 and Schedules 1–2, and EIA ss. 66/66.5 — laws-lois returned the table-of-contents shell rather than the section text for those. The section NUMBERS are confirmed because they are cited in CRA's own "References — Legislation" blocks on pages 1–5 above; the numeric values come from CRA/Revenu Québec, which is the administering authority. - Manitoba HE Levy and Newfoundland HAPSET rate schedules. INFERRED, NOT READ: monthly ceilings (ceiling_monthly) are arithmetic — annual ceiling divided by 12 — and are given for convenience; Canadian payroll does not actually use monthly ceilings, it uses per-pay-period pro-ration of the CAD 3,500 exemption plus a year-to-date cap. The EI employer rates 2.282% and 1.82% are computed as 1.4 x the published employee rates; CRA publishes the employer MAXIMUM (CAD 1,572.30 / CAD 1,253.98) rather than the employer percentage, and both reconcile exactly. BUYER-FACING CAVEAT: the effective_from of 2026-01-01 covers the whole set, but the components have different setting authorities and different announcement calendars (EI in September, CPP ceilings in November, Quebec parameters in late November). They will not all move together. Researched against primary instruments and independently challenged by a second verification pass before being served (2026-08-08). Employee and employer shares are stated separately: the employee figure is what leaves the payslip, the employer figure is cost of employment and is not a deduction.
