Required inputs

Before computing any CPP or EI figure, you MUST know:

1. Date of birth -- determines whether CPP contributions are required (age 18-70 range)
2. Province of residence -- Quebec residents use QPP, not CPP (this skill does NOT cover QPP)
3. Net self-employment income for the tax year -- CPP is based on current year, not prior year
4. Is the client also employed (T4 income)? -- employee CPP already paid reduces self-employed obligation
5. Has the client opted in to EI? -- EI is voluntary for self-employed
6. Is the client receiving a CPP disability or retirement pension? -- may affect contribution obligations
7. Did the client turn 18 or 70 during the tax year? -- pro-rata calculation required

If province is Quebec, STOP. This skill covers CPP only. QPP has different rates and thresholds.

Refusal catalogue

• R-CA-CPP-1 -- Quebec resident — Trigger: client resides in Quebec. Message: "Quebec Pension Plan (QPP) applies instead of CPP. QPP has different rates (6.40% employee / 12.80% self-employed for 2025). This skill does NOT cover QPP. Please escalate to a practitioner with QPP expertise."
• R-CA-CPP-2 -- Disability pension interaction — Trigger: client receives a CPP disability pension and asks about contribution obligations or benefit impacts. Message: "CPP disability pension interactions with self-employment contributions are complex and outside this skill's scope. Please escalate to a licensed Canadian CPA."
• R-CA-CPP-3 -- International social security agreement — Trigger: client asks about CPP credits under a bilateral social security agreement. Message: "International social security agreements require case-specific analysis. Please escalate to a licensed Canadian CPA familiar with treaty provisions."

Section 4 -- CPP eligibility and computation rules

4.1 CPP eligibility (Tier 1)

CPP eligibility table (Canada Pension Plan Act, s. 10)

Condition	CPP Obligation
Age 18 to 69 (inclusive) with net self-employment earnings > $3,500	MUST contribute
Age 70 or older	EXEMPT -- no CPP contributions required
Under age 18	EXEMPT -- no CPP contributions required
Receiving CPP retirement pension and age 60-64	MUST contribute (mandatory since 2012)
Receiving CPP retirement pension and age 65-69	MAY elect to stop contributing (file Form CPT30)
Receiving CPP disability pension	EXEMPT -- do not contribute
Net self-employment earnings <= $3,500 (basic exemption)	No CPP payable (earnings below floor)

4.2 CPP1 computation (Tier 1)

• CPP1 computation formula — pensionable_earnings = min(net_self_employment_income, $71,300) - $3,500 pensionable_earnings = max(pensionable_earnings, 0) cpp1 = pensionable_earnings x 11.90% cpp1 = min(cpp1, $8,068.20)

4.3 CPP2 computation (Tier 1)

• CPP2 computation formula — cpp2_earnings = min(net_self_employment_income, $81,200) - $71,300 cpp2_earnings = max(cpp2_earnings, 0) cpp2 = cpp2_earnings x 8.00% cpp2 = min(cpp2, $792.00) (Canada Pension Plan Act (as amended by Bill C-97, 2024))

4.4 Schedule 8 computation (Tier 1)

Schedule 8 computation table

Line	Description	Computation
Line 1	Total CPP pensionable employment income (from T4 slips)	Sum of Box 26 from all T4s
Line 2	CPP contributions deducted (from T4 slips)	Sum of Box 16 from all T4s
Line 3	Net self-employment earnings	From line 12200 of T1
Line 4	Total pensionable earnings	Line 1 + Line 3
Line 5	Basic exemption	$3,500 (or pro-rated if partial year)
Line 6	Maximum contributory earnings	min(Line 4, YMPE) - Line 5
Line 7	CPP contributions on self-employment	(Line 6 x 11.90%) - Line 2
Line 8	CPP2 additional contributions	Per Step 4.3 above
Line 9	Total contributions payable	Line 7 + Line 8

• Key rule — If the client also has T4 employment income with CPP already deducted, the employee CPP contributions (Line 2) are subtracted from the total obligation. If T4 CPP contributions already cover the maximum, self-employed CPP = $0.

4.5 Tax treatment of self-employed CPP (Tier 1)

• CPP1 split — Employer-equivalent half (50%) is a deduction from net income (line 22200). Employee-equivalent half (50%) is a non-refundable tax credit (line 30800, 15% federal credit). (Income Tax Act, s. 60(e), s. 118.7)
• CPP2 split — Employer-equivalent half (50%) is a deduction from net income (line 22215). Employee-equivalent half (50%) is a non-refundable tax credit (line 30800, 15% federal credit). (Income Tax Act, s. 60(e), s. 118.7)

The deduction is more valuable at higher marginal rates. The credit is worth a flat 15% regardless of income.

4.6 EI for self-employed (Tier 1)

• EI voluntary opt-in rules — EI is voluntary for self-employed. To opt in, register with Service Canada. 12-month waiting period before claiming benefits. Once benefits are claimed, cannot opt out. Self-employed EI covers SPECIAL BENEFITS ONLY (maternity, parental, sickness, compassionate care, family caregiver). It does NOT cover regular unemployment benefits. (Employment Insurance Act, Part VII.1, s. 152.07-152.21)
• EI premium formula — ei_premium = min(net_self_employment_income, $65,700) x 1.64% ei_premium = min(ei_premium, $1,077.48)
• EI premium credit — EI premiums are claimed as a non-refundable tax credit on line 31200 (15% federal credit).

Section 5 -- Age exemptions and pro-rata rules

Age exemptions and pro-rata table (Canada Pension Plan Act, s. 12, s. 13)

Age Event	CPP Treatment	EI Treatment
Turn 18 during the year	Contribute from month after 18th birthday	No age restriction
Age 18-69 all year	Full year contributions	Full year EI (if opted in)
Turn 70 during the year	Contribute up to and including month of 70th birthday	No age restriction
Age 70+ at start of year	NO CPP contributions	EI still available (if opted in)
Under 18 all year	NO CPP contributions	No age restriction

• Pro-rata basic exemption formula — pro_rata_exemption = ($3,500 / 12) x number_of_contributory_months (Canada Pension Plan Act, s. 12, s. 13)

6.1 Overpayment recovery (Tier 1)

Overpayment recovery table (Income Tax Act, s. 118.7)

Overpayment Type	How Recovered
CPP overpayment (employee contributions from T4s exceed maximum)	Claimed on line 44800 of T1 as refundable credit
CPP2 overpayment	Claimed on line 44801 of T1 as refundable credit
EI overpayment (multiple T4s)	Claimed on line 45000 of T1 as refundable credit

6.2 Payment and filing (Tier 1)

Payment and filing table

Requirement	Detail
How CPP is paid	Added to balance owing on T1 return (line 42100)
Filing deadline	June 15 (self-employed), but PAYMENT due April 30
Instalment requirements	If net tax owing exceeds $3,000 ($1,800 in Quebec) in current year AND either of the two prior years
Instalment dates	March 15, June 15, September 15, December 15
Interest on late payment	Prescribed rate set quarterly by CRA, compounded daily

CPP and EI are NOT paid separately by self-employed individuals. They are calculated on Schedule 8 and rolled into the T1 balance owing.

EC1 -- Client turns 70 mid-year (Tier 1)

Situation: Client's 70th birthday is in July 2025. Resolution: CPP contributions required January through July (7 months). Pro-rate the basic exemption: ($3,500 / 12) x 7 = $2,041.67. Schedule 8 handles the pro-rata calculation.

EC2 -- Client receiving CPP retirement pension, age 65-69 (Tier 2)

Situation: Client started CPP retirement pension at 65 and continues to be self-employed. Resolution: Contributions are optional for ages 65-69 if receiving CPP retirement. Client must file Form CPT30 to elect to stop contributing. If no CPT30 filed, contributions are required. Flag for reviewer -- confirm pension status and whether CPT30 has been filed.

EC3 -- Quebec resident (Tier 3)

Situation: Client resides in Quebec. Resolution: QPP applies instead of CPP. QPP has different rates (6.40% employee / 12.80% self-employed for 2025). This skill does NOT cover QPP. Escalate to practitioner with QPP expertise.

EC4 -- Self-employed EI opt-in within first 12 months (Tier 1)

Situation: Client opted in to EI in August 2025, wants to claim maternity benefits in January 2026. Resolution: 12-month waiting period applies. Client cannot claim benefits until August 2026. Premiums are still due for August-December 2025.

EC5 -- Net self-employment loss (Tier 1)

Situation: Client has a net self-employment loss (negative income). Resolution: No CPP contributions are payable on a loss. Pensionable earnings = $0. Unlike Malta SSC, there is NO minimum CPP contribution.

EC6 -- Religious exemption (Tier 2)

Situation: Client is a member of a religious group that has an approved exemption from CPP. Resolution: Form CPT17 must have been filed and approved. Flag for reviewer -- confirm exemption status with CRA before excluding CPP.

EC7 -- Non-resident self-employed in Canada (Tier 2)

Situation: Client is a non-resident of Canada earning self-employment income from Canadian sources. Resolution: CPP may still apply if the work is performed in Canada, regardless of residence. Flag for reviewer -- confirm whether the Canada-source self-employment triggers CPP obligations.

EC8 -- EI opt-out after opting in but before claiming (Tier 1)

Situation: Client opted in to EI for self-employed in 2024, has not claimed benefits, wants to opt out. Resolution: Client may opt out by December 31 of the current year if NO benefits have been claimed. Premiums paid for the opt-in year are refundable. Once any benefit has been claimed, the client cannot opt out.

Test 1 -- Standard self-employed, mid-range income

Input: Born 1985, Ontario resident, net self-employment income $50,000, no T4 income, no EI opt-in. Expected output: CPP1 = ($50,000 - $3,500) x 11.90% = $5,533.50. CPP2 = $0 (below YMPE). EI = $0 (not opted in). Line 22200 deduction = $2,766.75. Line 30800 credit base = $2,766.75.

Test 2 -- High-income, both ceilings hit

Input: Born 1978, Alberta resident, net self-employment income $120,000, no T4 income. Expected output: CPP1 = $8,068.20 (capped). CPP2 = $792.00 (capped). Total CPP = $8,860.20. Line 22200 deduction = $4,430.10. Line 30800 credit base = $4,430.10.

Test 3 -- Income between YMPE and YAMPE

Input: Born 1990, BC resident, net self-employment income $75,000, no T4 income. Expected output: CPP1 = $8,068.20 (capped at YMPE). CPP2 = ($75,000 - $71,300) x 8.00% = $296.00. Total CPP = $8,364.20.

Test 5 -- Self-employed with T4 employment income

Input: Born 1988, Ontario, T4 pensionable earnings $45,000, T4 CPP deducted $2,468.25, net self-employment income $40,000. Expected output: Combined pensionable earnings exceed YMPE. Self-employed CPP on Schedule 8 = $8,068.20 - $2,468.25 (employee) - $2,468.25 (deemed employer) = $3,131.70.

Test 6 -- EI opt-in calculation

Input: Opted-in self-employed, Ontario, net self-employment income $50,000. Expected output: EI premium = $50,000 x 1.64% = $820.00. Below maximum of $1,077.48.

Input: Born 1953, net self-employment income $80,000. Expected output: CPP = $0.00 (age 70+ exemption). No Schedule 8 required for CPP.

Test 8 -- Net loss

Input: Born 1985, net self-employment loss of ($5,000). Expected output: CPP = $0.00. No minimum contribution. No Schedule 8 obligation.

Prohibitions

• Prohibitions list — - NEVER compute CPP for Quebec residents -- QPP applies, not CPP - NEVER tell a self-employed client they must pay EI -- it is voluntary - NEVER forget to split CPP into deduction (line 22200) and credit (line 30800) -- both halves must be claimed - NEVER apply CPP to a client aged 70 or over at the start of the year - NEVER ignore T4 CPP already deducted when computing self-employed CPP on Schedule 8 - NEVER present CPP2 as optional -- it is mandatory for earnings above YMPE - NEVER combine CPP and EI into a single figure without showing the breakdown - NEVER advise on QPP rates using CPP figures -- they are different - NEVER state that self-employed EI covers regular (unemployment) benefits -- it covers special benefits only - NEVER compute figures without confirming the tax year -- rates change annually
